MIL-PRF-23269 / MIL-C-23269 CYR Glass Capacitors
Electronic Expediters stocks legacy military glass-dielectric capacitors associated with MIL-PRF-23269 and the earlier MIL-C-23269 designation. This family is identified by CYR style numbers and M23269 military part numbers. Expediters inventory includes CYR10, CYR51 and other CYR configurations used in established military and aerospace systems.
MIL-PRF-23269 is currently listed as inactive, but CYR and M23269 part numbers remain important for maintenance, replacement, legacy BOM support and sourcing of installed equipment. Examples found in Expediters inventory include CYR10C470FS, CYR10C330FS, CYR51C561JM and M23269/10-3150.
MIL-PRF-23269 and CYR Capacitor Identification
The CYR designation identifies fixed glass-dielectric capacitor styles associated with the MIL-PRF-23269 family. Depending on the specification sheet, CYR parts may use axial or radial wire-lead configurations. Buyers may encounter the same requirement as a CYR style number, an M23269 slash-sheet number or an older MIL-C-23269 reference.
Search M23269 and CYR Capacitors by Exact Part Number
For legacy military electronics, the exact part number matters. Search by the complete CYR number, M23269 number, manufacturer part number or available cross-reference. Expediters' inventory table below is generated from currently available stock records rather than a static catalog list.

CYR Glass Capacitors for Legacy and Replacement Requirements
CYR glass capacitors are commonly encountered in older military, aerospace, instrumentation and high-stability electronic assemblies. When a specification has become inactive for new design, procurement often shifts toward exact replacement, installed-base support, repair requirements and controlled substitution rather than new-design selection.
MIL-PRF-23269 Part-Number Relationships
An M23269 number identifies a military PIN under the 23269 family, while CYR identifies the associated capacitor style. Drawings and historical BOMs may use either format. When evaluating a replacement, compare the complete slash-sheet and PIN requirements rather than relying only on the family number.

MIL-PRF-23269 / CYR Questions
What is a CYR capacitor?
CYR is the military style designation used for fixed glass-dielectric capacitors associated with MIL-PRF-23269.
Is MIL-C-23269 the same family as MIL-PRF-23269?
MIL-C-23269 is the legacy designation. Later revisions use MIL-PRF-23269 terminology, while older drawings and inventories may continue to reference MIL-C-23269.
Can Expediters search M23269 slash-sheet numbers?
Yes. Search the inventory by the complete M23269 PIN, CYR style number or manufacturer number.
Does Expediters carry obsolete or difficult-to-source CYR capacitors?
Expediters maintains substantial legacy inventory, including military parts that may no longer be commonly stocked by broad-line distributors.
