CL31C100JGFNNNE Equivalent & Substitute Parts

Part Overview

The CL31C100JGFNNNE is a 10 pF ceramic capacitor manufactured by Samsung Electro-Mechanics, rated for 500V with C0G/NP0 temperature coefficient in 1206 (3216 Metric) surface mount package. This part is Active status and ROHS3 compliant. Substitute parts are identified when design requirements allow for equivalent electrical and mechanical parameters, or when higher voltage ratings provide additional design margin within the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Voltage Rating):

KGM31BCG2H100JT from KYOCERA AVX provides direct electrical and mechanical equivalence to the CL31C100JGFNNNE. Both parts are rated 500V with identical capacitance, tolerance, and temperature coefficient. This part is suitable for one-to-one replacement in applications where the 500V rating is specified. The reduced thickness (0.037" vs 0.055") provides additional design flexibility for space-constrained layouts while maintaining full electrical compatibility.

Upgrade Options (Higher Voltage Rating):

GRM31A5C2J100JW01D (Murata, 630V) and GRM31A5C3A100JW01D (Murata, 1kV) are voltage-upgraded alternatives. Both maintain identical capacitance, tolerance, and temperature coefficient specifications. These parts are suitable for applications where higher voltage margin is required or where design consolidation across multiple voltage ratings is beneficial. All three substitute parts are Active status with ROHS3 compliance and MSL 1 rating, ensuring equivalent reliability and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can KGM31BCG2H100JT replace CL31C100JGFNNNE in all applications?

A: Yes, KGM31BCG2H100JT is a direct equivalent. Both parts share identical electrical specifications (10 pF, ±5%, 500V, C0G/NP0) and mechanical footprint (1206 package). The thickness difference (0.037" vs 0.055") is within acceptable PCB assembly tolerances and does not affect electrical performance.

Q: What is the difference between the two Murata options?

A: GRM31A5C2J100JW01D is rated 630V, while GRM31A5C3A100JW01D is rated 1kV. Both maintain the same 10 pF capacitance and ±5% tolerance. Selection depends on circuit voltage requirements. The 1kV option provides maximum design margin but may have different cost and lead time characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. CL31C100JGFNNNE and all three substitute parts (KGM31BCG2H100JT, GRM31A5C2J100JW01D, GRM31A5C3A100JW01D) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use a higher voltage-rated part in place of the 500V specification?

A: Yes. GRM31A5C2J100JW01D (630V) and GRM31A5C3A100JW01D (1kV) are electrically compatible substitutes. Higher voltage ratings do not degrade performance in 500V applications and provide additional design margin.

Q: What is the impact of thickness variation on PCB assembly?

A: Thickness variation (0.037" to 0.055") is within standard PCB assembly process tolerances. All parts fit the 1206 package specification and are compatible with standard reflow soldering profiles. No assembly process modification is required.

Q: Are all substitute parts in active production?

A: Yes. CL31C100JGFNNNE, KGM31BCG2H100JT, GRM31A5C2J100JW01D, and GRM31A5C3A100JW01D are all Active status products with confirmed inventory availability.
