Substitute Part Grouping Explanation

Substitution eligibility for the 1812HC222KAT3A\SB is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 2200 pF (exact match required)
• Voltage Rating: 3000V (3kV) minimum
• Temperature Coefficient: X7R (ensures stable performance across operating temperature range)
• Package Format: 1812 (4532 Metric) surface mount configuration
• Tolerance: ±10% (acceptable variance specification)
• Compliance: ROHS3 and REACH Unaffected status

All identified substitute parts meet these criteria. Parametric equivalents from KYOCERA AVX (1812HC222KAT1A and KGM43JR73U222KV) are direct functional replacements with identical electrical characteristics. The direct manufacturer substitute from Cal-Chip Electronics (CHV1812N3K0222KXT) provides equivalent performance with a minor thickness variation (0.118" vs. 0.110" maximum) that remains within acceptable mechanical tolerances for standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified replacements for the 1812HC222KAT3A\SB based on electrical equivalence and regulatory compliance. Selection among these options should be based on packaging format availability and supply chain requirements:

1812HC222KAT1A (KYOCERA AVX) is available in Cut Tape (CT) and Digi-Reel packaging, suitable for mixed-volume procurement and manual assembly operations.

KGM43JR73U222KV (KYOCERA AVX, KGM - HV Series) is supplied in Tape & Reel format, optimized for high-volume automated assembly with 1965 units currently in stock.

CHV1812N3K0222KXT (Cal-Chip Electronics, CHV Series) is available in Tape & Reel format with the highest inventory level (5986 units). The maximum thickness specification of 0.118" (3.00mm) represents a 0.008" increase over the primary part but remains within standard PCB assembly clearance tolerances and does not affect electrical performance or thermal characteristics.

All parts maintain ROHS3 compliance, REACH Unaffected status, and Active product status, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can 1812HC222KAT1A be used as a direct replacement for 1812HC222KAT3A\SB?

A: Yes. Both parts are manufactured by KYOCERA AVX with identical electrical specifications: 2200 pF capacitance, ±10% tolerance, 3000V rating, X7R temperature coefficient, and -55°C to 125°C operating range. The difference is packaging format (Cut Tape & Digi-Reel vs. standard reel), which does not affect circuit performance.

Q: What is the difference between KGM43JR73U222KV and 1812HC222KAT3A\SB?

A: Both parts are KYOCERA AVX high-voltage ceramic capacitors with identical electrical and mechanical specifications. KGM43JR73U222KV belongs to the KGM - HV Series and is supplied in Tape & Reel format. The series designation reflects internal product line organization but does not indicate functional differences.

Q: Is CHV1812N3K0222KXT compatible with the original part despite the thickness difference?

A: Yes. CHV1812N3K0222KXT has a maximum thickness of 0.118" (3.00mm) compared to 0.110" (2.80mm) for the primary part. This 0.008" difference is within standard PCB assembly clearance tolerances and does not affect electrical performance, thermal characteristics, or circuit functionality. The part is suitable for standard surface mount assembly processes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (1812HC222KAT1A, KGM43JR73U222KV, and CHV1812N3K0222KXT) are ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement.

Q: Which substitute part should be selected for high-volume production?

A: KGM43JR73U222KV and CHV1812N3K0222KXT are both supplied in Tape & Reel format, optimized for automated assembly. CHV1812N3K0222KXT offers the highest current inventory (5986 units). Selection should be based on supply chain agreements, lead time requirements, and cost considerations.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All parts, including the primary 1812HC222KAT3A\SB, have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage, transport, or assembly.
