Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1812CC103MATME are qualified based on the following criteria:

Core Matching Parameters:

• Capacitance: 10000 pF (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Allowable Variations:

• Voltage Rating: Substitutes rated at 1000V (1kV) are acceptable as they exceed the 630V requirement
• Tolerance: Substitutes with ±10% tolerance are acceptable as they provide tighter specification than the ±20% original
• Manufacturer: Alternative manufacturers (TDK Corporation, KYOCERA AVX) are acceptable provided all core parameters match
• Physical Dimensions: Minor variations in length (0.177" to 0.181") and thickness (1.80mm to 2.21mm) are within acceptable tolerance for 1812 package form factor

All substitute parts maintain ROHS3 compliance, unlimited MSL rating, and Active product status.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified replacements for the 1812CC103MATME based on matching core electrical and mechanical parameters. Selection among substitutes should be based on the following factors:

1812AC103KAT1A (KYOCERA AVX): Provides upgraded voltage rating to 1000V with improved tolerance specification of ±10%. Maintains identical manufacturer and package form factor. Suitable for applications requiring higher voltage margin or tighter capacitance tolerance.

KGM43FR73A103MV (KYOCERA AVX, KGM - HV Series): Offers 1000V voltage rating with ±20% tolerance matching the original specification. Designated as high-voltage series component. Maintains identical manufacturer and package dimensions.

C4532X7R3A103K200KA (TDK Corporation): Provides 1000V voltage rating with ±10% tolerance from alternative manufacturer. Slight dimensional variation in length (0.177" vs 0.181") remains within 1812 package specification. Highest inventory availability at 86,839 pieces.

All substitutes maintain Active product status, ROHS3 compliance, and unlimited moisture sensitivity rating. Selection may be influenced by supply chain availability, cost considerations, or specific application voltage margin requirements.

Frequently Asked Questions (FAQ)

Q: Can 1812AC103KAT1A replace 1812CC103MATME in all applications?

A: Yes. The 1812AC103KAT1A matches all core parameters: 10000 pF capacitance, X7R temperature coefficient, 1812 package, and -55°C to 125°C operating range. The higher 1000V rating and tighter ±10% tolerance provide enhanced performance margins.

Q: What is the difference between KGM43FR73A103MV and 1812AC103KAT1A?

A: Both are KYOCERA AVX 1812 packages with 10000 pF and 1000V rating. The primary difference is tolerance: 1812AC103KAT1A specifies ±10% while KGM43FR73A103MV specifies ±20%. KGM43FR73A103MV is designated as part of the KGM - HV (high-voltage) series.

Q: Is the TDK C4532X7R3A103K200KA compatible with the original 1812CC103MATME footprint?

A: Yes. The C4532X7R3A103K200KA is a 1812 (4532 Metric) package with minor dimensional variation in length (0.177" vs 0.181"). This variation remains within standard 1812 package tolerance and is compatible with standard PCB footprints designed for 1812 components.

Q: Why do substitute parts have higher voltage ratings?

A: The substitute parts are rated at 1000V (1kV) compared to the original 630V rating. Higher voltage rating does not affect circuit operation at lower voltages and provides additional design margin. All other electrical characteristics remain compatible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (1812AC103KAT1A, KGM43FR73A103MV, and C4532X7R3A103K200KA) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the original component specifications.

Q: Can I use these substitutes interchangeably in production?

A: Yes, provided your application design accommodates the allowable parameter variations. Verify that your circuit design accepts the higher voltage rating and, where applicable, the tighter tolerance specification. All substitutes maintain identical package form factor and mounting type.
