Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1812CC103MATRE 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: Substitutes from qualified manufacturers (KYOCERA AVX, TDK Corporation) are acceptable
• Packaging: Tape & Reel (TR) packaging is acceptable for the same component specifications

All substitute parts maintain RoHS3 compliance, REACH unaffected status, and MSL 1 rating consistent with the main part.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified replacements for the 1812CC103MATRE based on matching core electrical and mechanical specifications. 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 lineage and package dimensions. 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 with marginal thickness increase.

C4532X7R3A103K200KA (TDK Corporation): Provides 1000V voltage rating with ±10% tolerance specification. Cross-manufacturer substitute with slight length dimension variation (4.50mm vs 4.60mm). Highest inventory availability among substitutes. Suitable for applications where TDK component qualification is required.

All substitutes maintain Active product status, full RoHS3 compliance, and MSL 1 rating. Thickness variations (1.80mm original vs 2.20-2.21mm substitutes) must be evaluated against PCB assembly clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can 1812AC103KAT1A replace 1812CC103MATRE in any application? A: Yes, 1812AC103KAT1A is a direct substitute. The higher 1000V rating provides additional voltage margin over the 630V requirement. The improved ±10% tolerance is compatible with circuits designed for ±20% tolerance. Physical package dimensions are identical.

Q: What is the difference between KGM43FR73A103MV and 1812AC103KAT1A? A: Both are KYOCERA AVX 10000 pF X7R 1812 capacitors rated at 1000V. The primary difference is tolerance specification: 1812AC103KAT1A offers ±10% while KGM43FR73A103MV maintains ±20%. KGM43FR73A103MV is designated as part of the KGM - HV (high-voltage) series. Selection depends on tolerance requirements for the application.

Q: Is the TDK C4532X7R3A103K200KA compatible with the original part? A: Yes, C4532X7R3A103K200KA is a qualified substitute. Electrical specifications match exactly (10000 pF, X7R, 1000V, ±10%). Physical dimensions show minor variation in length (4.50mm vs 4.60mm original), which is within standard PCB layout tolerance. Verify clearance in confined spaces before substitution.

Q: Why are substitute parts rated at 1000V when the original is 630V? A: Higher voltage rating substitutes are acceptable because they exceed the circuit requirement. A 1000V-rated capacitor safely operates at 630V with additional voltage margin, improving reliability and component longevity in the application.

Q: Does the increased thickness of substitute parts affect PCB assembly? A: Substitute parts have maximum thickness of 2.20-2.21mm compared to 1.80mm for the original. Verify PCB assembly clearance, solder reflow profile compatibility, and component placement constraints before substitution. Consult PCB design documentation for height restrictions.

Q: Are all substitute parts RoHS3 compliant? A: Yes, all substitute parts listed are ROHS3 compliant with REACH unaffected status, matching the original part's environmental compliance profile.
