MIL-PRF-14409 / MIL-C-14409 PC Variable Capacitors

Electronic Expediters stocks variable capacitor inventory associated with MIL-PRF-14409 and the legacy MIL-C-14409 designation.

MIL-PRF-14409 is an active military performance specification covering piston-type tubular-trimmer variable capacitors intended primarily for high-frequency trimming applications.

MIL-PRF-14409 / PC Variable Trimmer Capacitors Identification

Expediters catalogs PC-style variable capacitor inventory associated with this military family. Exact part identification is important because capacitance range, adjustment range, mechanical configuration and other requirements vary by style.

Search Expediters Inventory by Exact Part Number

Use the complete military style, specification reference or manufacturer part number whenever possible. Similar-looking military components can have materially different electrical, mechanical or environmental requirements.

Legacy and Current Military Requirements

Older drawings and inventory systems may continue to use MIL-C-14409 terminology even though the current specification designation is MIL-PRF-14409.

Hard-to-Find and Legacy Inventory

Expediters maintains substantial legacy electronic-component inventory that can be useful when broad-line distributors no longer stock an exact military style or historical manufacturer number. Inventory shown on this page is generated from currently available Expediters stock records.

MIL-PRF-14409 / PC Variable Trimmer Capacitors Questions

Can I search by the exact military style number?

Yes. Search by the complete military style, specification reference, manufacturer part number or available cross-reference.

Why are legacy specification numbers still important?

Military and aerospace equipment can remain in service for decades, so older drawings, BOMs and maintenance records often continue to reference specifications or styles that are inactive or canceled for new design.

Does a shared military family number mean two parts are interchangeable?

No. Always compare the complete applicable specification, detail sheet, electrical ratings, physical configuration and procurement requirements before considering a substitute.

Can Expediters help locate difficult-to-source parts?

Expediters specializes in extensive legacy electronic-component inventory, including military part numbers and styles that may be difficult to locate through current-production distribution channels.
