M39012 RF connectors are part-numbered coaxial radio-frequency connectors associated with the MIL-PRF-39012 performance specification. Electronic Expediters maintains extensive M39012-related connector inventory and provides exact part-number searching for procurement, maintenance, repair, aerospace, defense, industrial and legacy-equipment sourcing requirements.
This guide provides an overview of the M39012 family, explains how specification-sheet-based part numbers are used, and gives buyers and engineers a direct path into current Electronic Expediters inventory.

What Is MIL-PRF-39012?
MIL-PRF-39012 is the United States Department of Defense performance specification covering general requirements and tests for radio-frequency connectors used with flexible RF cables and certain other coaxial transmission lines.
The general specification works together with individual specification sheets that define particular connector configurations. Those sheets can distinguish connector series, cable or uncabled construction, contact configuration, mounting method, mechanical configuration and other requirements.
The Defense Logistics Agency currently lists MIL-PRF-39012 as an active specification. Because specifications and individual specification sheets can be revised, procurement and engineering decisions should always be checked against the current official document and the applicable specification sheet.

Understanding M39012 Part Numbers
Many M39012 part or identifying numbers use a format based on the general specification, an applicable specification-sheet number and a dash-number or configuration identifier. A typical catalog reference can therefore appear in a form such as M39012/16-0102 or M39012/60-3001.
The number following the slash identifies an applicable specification sheet. The characters following that sheet designation identify a particular configuration defined by that sheet. Buyers should use the complete part number whenever possible rather than relying only on the base term M39012.
Electronic Expediters inventory currently includes numerous M39012 families, including references such as:
- M39012/16 series
- M39012/21 series
- M39012/22 series
- M39012/55 series
- M39012/56 series
- M39012/60 series
- M39012/79 series
- M39012/80 series
Those examples represent only part of the M39012 inventory available through the Expediters catalog.
Search Electronic Expediters for M39012 Connectors
Electronic Expediters maintains hundreds of active M39012-related connector listings. Many exact M39012 part numbers also appear in multiple inventory records because different lots, date codes, manufacturers or inventory sources may exist for the same underlying part number.
If you know the exact M39012 number, enter the complete part number in the Expediters search box. Exact part-number searching is the fastest way to identify matching inventory while minimizing unrelated connector results.
You can also search current M39012 inventory or browse the broader electronic and RF connector inventory.
M39012 Connector Sourcing Considerations
When sourcing an M39012 connector, the complete specification-based part number is important because superficially similar coaxial connectors can differ in electrical, mechanical, mounting, contact, cable and qualification requirements.
Before substituting or purchasing an M39012 connector, procurement and engineering teams should normally verify:
- the complete M39012 part or identifying number;
- the applicable MIL-PRF-39012 specification sheet;
- connector series and physical interface;
- plug or receptacle configuration;
- pin or socket contact configuration;
- cabled or uncabled construction;
- mounting style and mechanical configuration;
- required RF and environmental performance;
- manufacturer and qualification requirements when applicable;
- date-code, lot or documentation requirements for the specific procurement.
These checks are especially important in aerospace, defense, communications and legacy-system applications where the procurement requirement may reference a specific specification revision or qualified product.
M39012 Qualification and QPD Verification
MIL-PRF-39012 is associated with qualification requirements. DLA records indicate that the former QPL-39012 listing was transformed into the electronic Qualified Products Database, or QPD.
When a purchase order, drawing or engineering requirement calls for qualified-product status, buyers should verify the applicable manufacturer and product directly through the official government qualification resources rather than assuming that a commercially similar RF connector satisfies the requirement.

M39012 RF Connector Families in the Expediters Database
The Expediters database contains many specification-sheet families and exact M39012 part numbers. Some part numbers are represented by more than one inventory record because separate lots or date codes have been cataloged independently.
Examples of heavily represented M39012 part-number families in the current database include:
- M39012/60-3001
- M39012/16-0102
- M39012/22-0001
- M39012/21-0002
- M39012/56-3026
- M39012/55-3026
Use the site search for the full number when sourcing one of these or another M39012 configuration. The search system is designed to recognize exact part-number queries and consolidate relevant inventory around the requested component.
M39012 and Commercial RF Connector Descriptions
Some M39012 specification sheets correspond to familiar coaxial RF connector families and configurations. A commercial description such as BNC, TNC or SMA can help describe the general interface, but it should not be treated as a substitute for the complete specification-based part number.
Two connectors that appear mechanically similar may not automatically satisfy the same specification, qualification or performance requirement. Use the applicable M39012 specification sheet and procurement documentation as the controlling reference.
Frequently Asked Questions About M39012 Connectors
What does M39012 mean?
M39012 refers to the part-number family associated with MIL-PRF-39012, the DoD performance specification covering coaxial radio-frequency connectors.
Is MIL-PRF-39012 still active?
Yes. DLA ASSIST currently identifies MIL-PRF-39012 as an active specification. Because revisions can occur, always verify the current document before making a specification-controlled procurement decision.
Does Electronic Expediters carry M39012 RF connectors?
Yes. The Expediters catalog contains hundreds of active M39012-related inventory records across numerous specification-sheet and part-number families.
How should I search for an M39012 connector?
Use the complete M39012 part number whenever available. For example, searching an exact number such as M39012/60-3001 is more precise than searching only for M39012 or RF connector.
Are all connectors with the same commercial connector style interchangeable with an M39012 part?
No. A similar commercial connector description does not by itself establish compliance or interchangeability. Verify the complete part number, applicable specification sheet, required performance and any qualification requirements.
Why can the same M39012 part number appear in more than one Expediters listing?
Electronic Expediters maintains inventory records that can differ by lot, date code, manufacturer reference or acquisition source. Multiple listings can therefore represent the same underlying M39012 part number while preserving inventory-specific information.
Need a Specific M39012 Part?
Search the complete part number in the Electronic Expediters search field. If the required configuration is not immediately visible or the product is shown as RFQ, contact Electronic Expediters with the complete M39012 number and any required manufacturer, qualification, lot, date-code or documentation requirements.
