KGM43BCG3A331JS Equivalent & Substitute Parts

Part Overview

The KGM43BCG3A331JS is a 330 pF ±5% high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated for 1000V (1kV) operation in a 1812 (4532 Metric) surface-mount package. This part is classified as Active product status and is designed for general-purpose high-voltage applications requiring stable C0G/NP0 temperature characteristics. Substitute parts become necessary when primary manufacturer availability is limited, when geographic supply chain requirements necessitate alternative sourcing, or when design flexibility allows for equivalent components with identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The YAGEO CC1812JKNPOCBN331 qualifies as a direct substitute for the KGM43BCG3A331JS based on strict electrical and mechanical parameter matching. The following parameters determine substitution eligibility:

• Capacitance Value: Identical at 330 pF
• Tolerance: Matching ±5%
• Voltage Rating: Both rated for 1000V (1kV)
• Temperature Coefficient: C0G/NP0 match ensures temperature stability across the operating range of -55°C ~ 125°C
• Package Type: Both use 1812 (4532 Metric) surface-mount ceramic capacitor packages
• RoHS Compliance: Both ROHS3 Compliant
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)
• Mounting Technology: Both are multilayer ceramic capacitors (MLCC) with surface-mount design

The substitute part meets all critical electrical requirements and packaging specifications required for pin-for-pin and footprint-compatible replacement.

Parameter Comparison

Engineering Selection Recommendations

Both the KGM43BCG3A331JS and CC1812JKNPOCBN331 are Active-status products that meet identical electrical specifications and regulatory requirements. The YAGEO CC1812JKNPOCBN331 substitute part is suitable for applications requiring:

• High-voltage ceramic capacitor functionality in the 330 pF, 1kV classification
• ROHS3 compliance and REACH Unaffected status for regulated industries
• Surface-mount installation in 1812 (4532 Metric) package footprints
• C0G/NP0 temperature stability across -55°C to 125°C operating range
• Moisture tolerance rated at MSL 1 (Unlimited)

The negligible dimensional difference in length (0.181" vs 0.177", a 0.004" variance) remains within standard PCB footprint tolerances for 1812 packages and does not impact electrical performance or mechanical fit.

Frequently Asked Questions (FAQ)

Q: Are the KGM43BCG3A331JS and CC1812JKNPOCBN331 electrically identical?

A: Both parts share identical electrical specifications: 330 pF capacitance, ±5% tolerance, 1000V rating, and C0G/NP0 temperature coefficient. They are direct electrical equivalents suitable for the same circuit applications.

Q: Can the YAGEO part be used as a direct replacement without PCB redesign?

A: The 1812 (4532 Metric) package and mounting technology are identical between both parts. The minor length difference (4.60mm vs 4.50mm) is within standard 1812 package tolerances and does not require footprint modification.

Q: What are the regulatory compliance considerations?

A: Both parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS code 8532.24.0020. No compliance differences exist between the two manufacturers' parts.

Q: Are moisture sensitivity levels the same?

A: Both parts carry MSL rating 1 (Unlimited moisture sensitivity level), indicating no baking requirements and unlimited shelf life in standard conditions.

Q: Does the temperature coefficient notation difference (C0G vs NPO) matter?

A: C0G and NPO designate the same temperature coefficient characteristic and behavior. The notation difference reflects manufacturer convention only and indicates identical thermal stability performance.
