Equivalent & Substitute Parts for 1812HA101MATME

Part Overview

The 1812HA101MATME is a 100 pF ceramic capacitor rated for 3000V (3kV) with C0G/NP0 temperature coefficient, manufactured by KYOCERA AVX in 1812 (4532 Metric) package format. This high-voltage multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across temperature ranges from -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching electrical specifications, mechanical compatibility, and regulatory compliance to support component procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812HA101MATME is determined by the following critical parameters:

• Capacitance Value: Must be 100 pF
• Voltage Rating: Must be 3000V (3kV) or higher
• Temperature Coefficient: Must be C0G or NP0
• Package Format: Must be 1812 (4532 Metric) surface mount
• Operating Temperature Range: Must support -55°C to 125°C
• Regulatory Compliance: Must maintain ROHS3 compliance and MSL 1 rating

All identified substitute parts meet these core electrical and mechanical requirements. Variations in tolerance (±20%, ±10%, ±5%) and physical dimensions within the 1812 package envelope do not preclude substitution, as these represent performance enhancements or minor dimensional tolerances acceptable within the 1812 form factor specification.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components with ROHS3 compliance and MSL 1 rating, meeting the regulatory and environmental requirements of the original 1812HA101MATME specification.

1812HA101KAT1A (KYOCERA AVX): Direct manufacturer equivalent with improved tolerance specification (±10% versus ±20%). Identical physical dimensions and electrical ratings. Suitable for applications requiring tighter capacitance tolerance while maintaining full compatibility with the original design.

KGM43BCG3U101JV (KYOCERA AVX, KGM - HV Series): High-voltage series variant with superior tolerance specification (±5%). Identical electrical ratings and physical dimensions. Appropriate for precision applications where capacitance stability is critical.

C4532C0G3F101K160KA (TDK Corporation, C Series): Cross-manufacturer substitute from TDK with ±10% tolerance. Meets all electrical specifications. Physical dimensions show minor variations: length 4.50mm (versus 4.60mm) and thickness 1.80mm (versus 1.45mm). These dimensional differences remain within the 1812 package envelope and do not affect PCB footprint compatibility for standard 1812 land patterns.

Frequently Asked Questions (FAQ)

Q: Can 1812HA101KAT1A replace 1812HA101MATME in existing designs?

A: Yes. Both parts share identical capacitance (100 pF), voltage rating (3000V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and physical package format (1812/4532 Metric). The substitute offers improved tolerance (±10% versus ±20%), making it a direct upgrade with no design modifications required.

Q: What is the difference between the tolerance specifications?

A: Tolerance defines the allowable deviation from the nominal 100 pF capacitance value. The main part allows ±20% deviation (80–120 pF), while substitute parts offer ±10% (90–110 pF) or ±5% (95–105 pF). Tighter tolerance specifications provide greater capacitance stability and are suitable for precision circuit applications.

Q: Is the TDK C4532C0G3F101K160KA compatible with the original 1812HA101MATME footprint?

A: Yes. Although the TDK part shows minor dimensional variations (length 4.50mm versus 4.60mm, thickness 1.80mm versus 1.45mm), these differences remain within the 1812 package specification envelope. Standard 1812 PCB land patterns accommodate these variations without modification.

Q: Do all substitute parts maintain ROHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity) rating, matching the regulatory and environmental compliance profile of the original 1812HA101MATME.

Q: Can substitute parts be mixed in the same production batch?

A: Yes. All substitute parts meet identical electrical specifications for capacitance, voltage rating, temperature coefficient, and operating temperature range. Cross-manufacturer substitution (KYOCERA AVX to TDK) is permissible provided design documentation is updated to reflect the approved equivalent parts list.
