Substitute Part Grouping Explanation

Substitute parts for the 1812CC103MAT1Q are qualified based on the following criteria:

• Identical capacitance value: 10000 pF
• Identical package / case: 1812 (4532 Metric)
• Identical temperature coefficient: X7R
• Identical operating temperature range: -55°C ~ 125°C
• Identical mounting type: Surface Mount, MLCC
• Equal or higher voltage rating (630V minimum)
• ROHS3 compliance maintained
• MSL rating of 1 (Unlimited) maintained

The three substitute parts listed meet all these criteria while offering upgraded voltage ratings of 1000V (1kV), providing enhanced design margin in high-voltage applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance. The primary distinction among substitutes is voltage rating and tolerance specification.

1812AC103KAT1A and C4532X7R3A103K200KA offer ±10% tolerance with 1000V rating, providing tighter capacitance control suitable for precision applications. KGM43FR73A103MV maintains ±20% tolerance matching the original part while upgrading to 1000V rating.

Physical dimensions remain compatible across all substitutes within the 1812 package family. Thickness increases from 1.80mm to 2.20mm on upgraded parts due to higher voltage construction. Length variation between KYOCERA AVX (4.60mm) and TDK (4.50mm) parts remains within 1812 package specification tolerance.

Frequently Asked Questions (FAQ)

Q: Can 1812AC103KAT1A directly replace 1812CC103MAT1Q?

A: Yes. Both parts share identical capacitance (10000 pF), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), and 1812 package dimensions. The substitute offers higher voltage rating (1000V vs 630V) and tighter tolerance (±10% vs ±20%), making it functionally compatible with improved specifications.

Q: What is the thickness difference between the main part and substitutes?

A: The main part 1812CC103MAT1Q has maximum thickness of 1.80mm. All three substitute parts have maximum thickness of 2.20mm or 2.21mm. This increase accommodates higher voltage dielectric construction. Verify PCB layout clearance before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (1812AC103KAT1A, KGM43FR73A103MV, C4532X7R3A103K200KA) are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original part's environmental and regulatory status.

Q: What is the difference between KYOCERA AVX and TDK substitute options?

A: Both manufacturers provide equivalent 10000 pF, 1000V, X7R ceramic capacitors in 1812 package. KYOCERA AVX offers two options with different tolerance specifications (±10% and ±20%). TDK's C4532X7R3A103K200KA provides ±10% tolerance. Physical dimensions vary slightly (TDK: 4.50mm length vs KYOCERA AVX: 4.60mm length), both within 1812 specification.

Q: Can I use KGM43FR73A103MV if I need ±20% tolerance?

A: Yes. KGM43FR73A103MV maintains ±20% tolerance identical to the original part while providing 1000V voltage rating upgrade. This part is suitable for applications where tolerance specification matches the original design requirement.
