MIL-C-11272 CY Glass Capacitors - Legacy Military Inventory
Electronic Expediters stocks legacy fixed glass-dielectric capacitors associated with MIL-C-11272 and CY military style numbers.
MIL-C-11272 has long been inactive for new design. Government qualification documentation directs use toward MIL-PRF-23269 for applicable replacement requirements, although exact legacy CY numbers remain important for installed equipment, repair and maintenance.
MIL-C-11272 / CY Legacy Glass Capacitors Identification
MIL-C-11272 parts are commonly encountered as CY style numbers such as CY06, CY07, CY08, CY10 and related configurations. The complete style and specification-sheet requirement should be checked when evaluating a replacement.
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
MIL-C-11272 and MIL-PRF-23269 are closely related in legacy glass-capacitor procurement. Some former CY styles have corresponding CYR requirements under MIL-PRF-23269, while individual legacy detail sheets may have their own replacement instructions.
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-C-11272 / CY Legacy Glass 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.
