Key Parameters

Substitute Part Grouping Explanation

Substitution of the M39014/011521 requires compliance with the following critical parameters:

• Capacitance Value: Exact match at 1500 pF
• Voltage Rating: Minimum 100V rated voltage
• Mounting Configuration: Through-hole radial package with 0.200" (5.08mm) lead spacing
• Physical Dimensions: 0.190" L x 0.090" W with compatible height-seated specifications
• Operating Temperature: Continuous operation across -55°C to 125°C range
• Lead Style: Formed leads consistent with original design
• Reliability Classification: High-reliability applications with R (0.01%) failure rate

The identified substitute parts maintain these core electrical and mechanical compatibility requirements while offering improvements in temperature coefficient stability and tighter capacitance tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CCR05CG152FR and CCR05CG152JR substitute parts are active production components from qualified military-specification manufacturers (KYOCERA AVX and KEMET respectively), addressing the obsolescence of the M39014/011521. The substitute parts exceed the original specification through improved capacitance tolerance (±1% and ±5% versus ±20%) and superior temperature coefficient stability (C0G/NP0 versus BX), while maintaining identical electrical ratings, physical package dimensions, and high-reliability failure rate classifications.

Selection between the two substitute parts depends on tolerance requirements: CCR05CG152FR provides the tightest tolerance (±1%) for precision-critical applications, while CCR05CG152JR offers balanced performance (±5%) with REACH compliance status. Both parts support direct drop-in replacement at the board level without modification to PCB footprints or through-hole spacing.

Frequently Asked Questions (FAQ)

Q: Can the CCR05CG152FR or CCR05CG152JR be used as direct replacements for the M39014/011521?

A: Yes. Both substitute parts maintain the identical 1500 pF capacitance, 100V voltage rating, 0.200" lead spacing, and radial through-hole package configuration required for direct mechanical and electrical compatibility.

Q: What is the difference between the CCR05CG152FR and CCR05CG152JR?

A: The primary differences are capacitance tolerance (±1% for CCR05CG152FR versus ±5% for CCR05CG152JR) and REACH compliance status. Both parts feature C0G/NP0 temperature coefficients and identical physical dimensions.

Q: Are the substitute parts suitable for the same high-reliability applications as the original M39014/011521?

A: Yes. Both substitute parts maintain the R (0.01%) failure rate classification and operate across the full -55°C to 125°C temperature range required for high-reliability applications.

Q: Why do the substitute parts have C0G/NP0 temperature coefficients instead of BX?

A: C0G/NP0 temperature coefficients provide superior stability across the operating temperature range compared to BX, offering improved performance characteristics while maintaining compliance with the same operating temperature specification.

Q: Are there PCB layout considerations for using these substitute parts?

A: No. The identical 0.190" L x 0.090" W physical dimensions and 0.200" (5.08mm) lead spacing ensure compatibility with existing PCB footprints designed for the M39014/011521 without modification.
