Substitute Part Grouping Explanation

Substitution eligibility for the CKR22CG392JS is determined by the following criteria:

• Capacitance Value: Must be 3900 pF (no deviation permitted)
• Voltage Rating: Must be 50V or higher
• Temperature Coefficient: Must be C0G/NP0 for temperature stability
• Operating Temperature Range: Must support -55°C to 125°C
• Mounting Type: Must be Through Hole
• Package: Must be 2-DIP with identical lead spacing (0.325" / 8.25mm)
• Mechanical Dimensions: Must match 0.260" L x 0.092" W (6.60mm x 2.34mm) and height 0.175" (4.45mm)
• Military Specification: Must comply with MIL-PRF-39014
• Failure Rate: Must maintain S-level (0.001%) reliability

The CKR22CG392FS qualifies as a direct substitute based on these parameters. While tolerance is improved to ±1%, all other electrical and mechanical specifications remain identical, ensuring drop-in compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both CKR22CG392JS and CKR22CG392FS are active military-grade components manufactured by KYOCERA AVX under MIL-PRF-39014 specification. The CKR22CG392FS provides improved tolerance performance (±1% versus ±5%) while maintaining identical electrical ratings, mechanical compatibility, and reliability characteristics. Both parts are RoHS non-compliant and REACH unaffected, with equivalent failure rates at S-level (0.001%). Selection between these parts depends on circuit tolerance requirements; the CKR22CG392FS is suitable for applications requiring tighter capacitance control, while the CKR22CG392JS remains appropriate for standard tolerance applications.

Frequently Asked Questions (FAQ)

Q: Can CKR22CG392FS replace CKR22CG392JS in existing designs?

A: Yes. The CKR22CG392FS is a direct substitute with identical electrical ratings (3900 pF, 50V, C0G/NP0), mechanical dimensions, lead spacing, and package configuration. The improved tolerance (±1% versus ±5%) provides enhanced performance without requiring circuit redesign.

Q: Are there differences in physical dimensions between these parts?

A: No. Both parts share identical dimensions: 0.260" L x 0.092" W (6.60mm x 2.34mm), height 0.175" (4.45mm), and lead spacing 0.325" (8.25mm). They are mechanically interchangeable in 2-DIP through-hole applications.

Q: Do both parts meet the same military specifications?

A: Yes. Both CKR22CG392JS and CKR22CG392FS comply with MIL-PRF-39014 military specification and maintain S-level failure rate (0.001%) for high-reliability applications.

Q: What is the primary difference between these substitute parts?

A: The tolerance specification differs: CKR22CG392JS is ±5%, while CKR22CG392FS is ±1%. All other parameters, including capacitance value, voltage rating, temperature coefficient, and operating temperature range, are identical.

Q: Are both parts currently available?

A: Yes. CKR22CG392JS has 695 units in stock, and CKR22CG392FS has 852 units in stock, both in new original condition with tube packaging.
