Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CL31C181JGFNFNE are categorized into two groups based on electrical parameter compatibility:

Direct Equivalents (Same Voltage Rating - 500V): Parts maintaining identical voltage rating (500V) with matching capacitance (180 pF), tolerance (±5%), temperature coefficient (C0G/NP0), and package (1206). These parts are fully interchangeable without circuit redesign.

Upgrade Substitutes (Higher Voltage Rating - 630V): Parts with elevated voltage rating (630V) while maintaining all other electrical parameters (180 pF capacitance, ±5% tolerance, C0G/NP0 temperature coefficient, 1206 package). These provide enhanced voltage margin and are electrically compatible in applications rated for 500V operation.

Tolerance Upgrade Variant: Parts with tighter tolerance specification (±2% instead of ±5%) at the same voltage rating (500V), providing improved capacitance accuracy while maintaining all other parameters.

All substitute parts share identical package dimensions (1206/3216 Metric), surface mount mounting type, MSL Level 1 rating, and ROHS3 compliance, ensuring mechanical and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (500V Rating): KGM31BCG2H181JT (KYOCERA AVX) provides direct electrical equivalence with identical 500V rating and ±5% tolerance. This part is Active status with 2996 units in stock and reduced thickness (0.94mm vs. 1.40mm), offering improved PCB assembly compatibility. KGM31BCG2H181GT (KYOCERA AVX) offers the same direct replacement capability with enhanced ±2% tolerance specification for applications requiring tighter capacitance control, maintaining Active product status with 1508 units available.

For Voltage Margin Enhancement (630V Rating): C3216C0G2J181J060AA (TDK Corporation) and GRM31A5C2J181JW01D (Murata Electronics) both provide 630V rated alternatives, delivering 26% higher voltage margin while maintaining 180 pF capacitance and ±5% tolerance. GRM31A5C2J181JW01D is recommended as primary upgrade option due to Active product status and highest inventory availability (6715 units). C3216C0G2J181J060AA carries Last Time Buy status, indicating limited future availability.

All recommended substitutes maintain ROHS3 compliance, MSL Level 1 rating, and identical operating temperature range (-55°C to 125°C), ensuring full environmental and regulatory compatibility.

Frequently Asked Questions (FAQ)

Q: Can KGM31BCG2H181JT be used as a direct replacement for CL31C181JGFNFNE?

A: Yes. Both parts share identical electrical specifications: 180 pF capacitance, ±5% tolerance, 500V voltage rating, and C0G/NP0 temperature coefficient. Package dimensions (1206/3216 Metric) and mounting type (surface mount MLCC) are identical. The KGM31BCG2H181JT has reduced thickness (0.94mm vs. 1.40mm), which is mechanically compatible and may improve PCB assembly clearance.

Q: What is the difference between the 500V and 630V rated substitutes?

A: The 630V rated parts (C3216C0G2J181J060AA and GRM31A5C2J181JW01D) provide higher voltage margin for the same 180 pF capacitance and ±5% tolerance. These are suitable for applications where the circuit operates at 500V but requires additional voltage safety margin. All other electrical and mechanical parameters remain compatible.

Q: Why does KGM31BCG2H181GT have ±2% tolerance instead of ±5%?

A: KGM31BCG2H181GT is a tolerance upgrade variant offering tighter capacitance control (±2% vs. ±5%) at the same 500V rating. This part is suitable for precision applications requiring more stable capacitance values. It maintains identical voltage rating, package, and operating temperature range.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (KGM31BCG2H181JT, KGM31BCG2H181GT, C3216C0G2J181J060AA, and GRM31A5C2J181JW01D) are ROHS3 compliant with MSL Level 1 rating, matching the environmental and regulatory compliance of the original CL31C181JGFNFNE.

Q: Which substitute has the best inventory availability?

A: GRM31A5C2J181JW01D (Murata Electronics) has the highest inventory with 6715 units in stock. This 630V rated part is Active status and provides both direct electrical compatibility and voltage margin enhancement.

Q: Can I use a 630V rated part in a circuit designed for 500V?

A: Yes. A 630V rated capacitor is electrically compatible in a 500V circuit. The higher voltage rating provides additional safety margin without affecting circuit performance. All other parameters (capacitance, tolerance, temperature coefficient, package) remain identical to the original specification.
