Key Parameters

Substitute Part Grouping Explanation

Substitution of the M39014/011328 is based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 22 pF (exact match required)
• Voltage rating: 200V (minimum requirement)
• Temperature coefficient: BX (frequency stability specification)
• Operating temperature range: -55°C to 125°C (environmental envelope)
• Mounting configuration: Through-hole radial leads
• Lead spacing: 0.200" (5.08mm) for PCB compatibility
• Military specification compliance: MIL-PRF-39014, CKR05 series
• Failure rate classification: S (0.001%)

Allowable Variations:

• Tolerance: Substitute may have tighter tolerance (±10% acceptable for ±20% requirement)
• Product status: Active status preferred for obsolete components
• Manufacturer: Alternative qualified manufacturers within MIL-PRF-39014 specification
• Physical dimensions: Minor variations in height and length acceptable if lead spacing and mounting type remain unchanged

The M39014/01-1327 qualifies as a direct substitute based on full alignment with all mandatory parameters and improved tolerance specification.

Engineering Selection Recommendations

Primary Substitute: M39014/01-1327 (KYOCERA AVX)

The M39014/01-1327 is the qualified equivalent for the obsolete M39014/011328. Selection rationale is based on the following engineering factors:

Electrical Compatibility: Both components maintain identical capacitance (22 pF), voltage rating (200V), and temperature coefficient (BX) specifications. The substitute's ±10% tolerance is superior to the original ±20% tolerance, providing improved circuit performance without introducing incompatibility.

Environmental Suitability: Operating temperature range (-55°C to 125°C) and failure rate classification (S, 0.001%) are identical, confirming suitability for high-reliability applications.

Physical Compatibility: Lead spacing (0.200" / 5.08mm) and through-hole radial mounting configuration are exact matches, ensuring direct PCB footprint compatibility. The substitute's reduced seated height (0.200" versus 0.245") presents no compatibility issues and may provide clearance advantages in space-constrained layouts.

Specification Compliance: Both components comply with MIL-PRF-39014 and CKR05 series military specifications. The substitute maintains equivalent RoHS non-compliance status, ensuring consistency with existing system documentation.

Availability: The substitute is classified as active product status with 620 units in stock, addressing the obsolescence of the original component for both replacement and new production applications.

Frequently Asked Questions (FAQ)

Q: Can M39014/01-1327 be used as a direct replacement for M39014/011328 in existing assemblies?

A: Yes. The M39014/01-1327 is a direct substitute with identical electrical specifications (22 pF, 200V, BX temperature coefficient) and mechanical compatibility (0.200" lead spacing, through-hole radial configuration). PCB footprints are compatible without modification.

Q: What is the significance of the tolerance difference (±20% versus ±10%)?

A: The substitute's tighter ±10% tolerance represents improved capacitance accuracy. This is a beneficial change that does not create incompatibility; circuits designed for the original ±20% tolerance will function correctly with the more precise ±10% component.

Q: Are there any height clearance concerns with the lower-profile substitute?

A: No. The substitute's maximum seated height of 0.200" (5.08mm) is lower than the original 0.245" (6.22mm). This reduction provides additional clearance in space-constrained applications and does not affect electrical or mechanical compatibility.

Q: Do both components meet the same military specifications?

A: Yes. Both M39014/011328 and M39014/01-1327 comply with MIL-PRF-39014 and are part of the CKR05 series. Both maintain the S-class failure rate (0.001%) required for high-reliability applications.

Q: Why is the original part classified as obsolete?

A: The M39014/011328 is no longer manufactured by Cornell Dubilier Electronics. The M39014/01-1327 from KYOCERA AVX provides continued availability of this specification within the same military standard and series designation.

Q: Are there any RoHS compliance differences?

A: No. Both components are classified as RoHS non-compliant with identical compliance status. System documentation and regulatory filings require no modification.

Q: What is the lead style for both components?

A: Both components feature formed leads, a standard configuration for through-hole radial ceramic capacitors. Lead forming for specific PCB hole spacing is performed during assembly if required.
