MIL-PRF-39014 / MIL-C-39014 CKR Capacitors
Electronic Expediters inventories and sources capacitors associated with the MIL-PRF-39014 military capacitor family, historically referenced as MIL-C-39014. Buyers may encounter these components under the current MIL-PRF-39014 designation, legacy MIL-C-39014 terminology, M39014 part numbers, or CKR military style numbers.
MIL-PRF-39014 and CKR Capacitor Identification
MIL-PRF-39014 is the current military performance specification covering fixed, general-purpose ceramic dielectric capacitors in established reliability and non-established reliability configurations. Older procurement documents, drawings and bills of material may continue to reference the earlier MIL-C-39014 designation.

Legacy and Hard-to-Find CKR Capacitors
Military and aerospace programs frequently require electronic components long after the original production or design cycle. Expediters maintains an extensive historical component catalog and supports sourcing for legacy, obsolete and difficult-to-locate military capacitor requirements.
MIL-PRF-39014 Specification and Part-Number Relationships
A specification number identifies the broader capacitor requirements, while an individual M39014 part number identifies a more specific component configuration. CKR style designations provide another commonly used reference within the same military capacitor family.
For procurement purposes, the exact drawing or bill-of-material part number should always be used when available. A specification-family match alone should not be treated as confirmation that two individual capacitor part numbers are interchangeable.

MIL-PRF-39014 / CKR Questions
Is MIL-C-39014 the same as MIL-PRF-39014?
MIL-C-39014 is the older specification terminology. Current Department of Defense documentation uses MIL-PRF-39014, and current specification sheets may explicitly supersede earlier MIL-C-39014 sheets. Legacy records and bills of material may still use the MIL-C designation.
What does CKR mean on a military capacitor?
CKR is a military style designation used for capacitors within the MIL-PRF-39014 specification family. Individual CKR style numbers identify more specific component configurations.
What does an M39014 part number identify?
M39014 is the military part-number family associated with MIL-PRF-39014. The complete part number, including its slash-sheet and detail designation where applicable, is needed to identify the specific component requirement.
Can Expediters help locate obsolete CKR capacitors?
Yes. Expediters supports sourcing for current, legacy and difficult-to-find electronic components. Search the exact CKR or M39014 part number first, then contact Expediters when additional sourcing assistance is required.
