1812GA151MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1812GA151MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 150 pF, rated for 2000V operation, and featuring C0G/NP0 temperature stability. This surface-mount multilayer ceramic capacitor (MLCC) in 1812 (4532 metric) package is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching capacitance, voltage rating, temperature coefficient, package dimensions, and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812GA151MAT1A is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance value: 150 pF (exact match required)
• Temperature coefficient: C0G/NP0 (ensures stable performance across operating temperature range)
• Package / Case: 1812 (4532 Metric) (ensures mechanical and electrical compatibility)
• Mounting type: Surface Mount, MLCC (maintains assembly compatibility)

Secondary Compatibility Factors:

• Voltage rating: Equal to or greater than 2000V (higher voltage ratings provide design margin)
• Tolerance: Equal to or tighter than ±20% (tighter tolerances are acceptable upgrades)
• Operating temperature range: -55°C to 125°C (must match or exceed)
• RoHS and compliance status: ROHS3 compliant (regulatory requirement)

The substitute parts listed below meet all primary matching criteria and maintain or improve secondary compatibility factors.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity.

1812GA151JAT1A (KYOCERA AVX): This substitute offers improved tolerance specification (±5% versus ±20%), maintaining identical voltage rating (2000V) and package dimensions. Selection is appropriate when tighter capacitance tolerance is required without voltage derating.

1812GA151KAT1A (KYOCERA AVX): This substitute provides intermediate tolerance (±10%) while maintaining 2000V voltage rating and identical package specifications. Selection is appropriate for applications requiring tolerance improvement over the base part without cross-manufacturer sourcing.

C4532C0G3F151K160KA (TDK Corporation): This substitute offers elevated voltage rating (3000V versus 2000V) with ±10% tolerance and maintains C0G/NP0 temperature stability. Physical dimensions show minor variations: length 0.177" (4.50mm) versus 0.181" (4.60mm) and reduced thickness 0.071" (1.80mm) versus 0.087" (2.20mm). Selection is appropriate for applications requiring higher voltage margin or where compact form factor is beneficial. Cross-manufacturer sourcing introduces supply chain diversification.

Frequently Asked Questions (FAQ)

Q: Can 1812GA151JAT1A replace 1812GA151MAT1A directly?

A: Yes. Both parts share identical capacitance (150 pF), voltage rating (2000V), temperature coefficient (C0G/NP0), and package dimensions (1812/4532 metric). The substitute features tighter tolerance (±5% versus ±20%), which is a functional improvement. No circuit redesign is required.

Q: What is the difference between 1812GA151KAT1A and 1812GA151JAT1A?

A: Both are KYOCERA AVX parts with identical capacitance, voltage, and package specifications. The primary difference is tolerance: 1812GA151KAT1A is ±10% while 1812GA151JAT1A is ±5%. Selection depends on tolerance requirements for the specific application.

Q: Can C4532C0G3F151K160KA be used as a direct replacement?

A: Electrical substitution is valid: capacitance (150 pF), temperature coefficient (C0G/NP0), and voltage rating (3000V, which exceeds the 2000V requirement) are compatible. Physical dimensions show minor variations: the TDK part is slightly shorter (0.177" versus 0.181") and thinner (0.071" versus 0.087"). Verify PCB layout and assembly equipment compatibility before implementation, particularly for automated placement systems with strict height tolerances.

Q: Why would I select the TDK C4532C0G3F151K160KA over KYOCERA AVX alternatives?

A: The TDK part provides higher voltage rating (3000V), offering additional design margin for high-voltage applications. The reduced thickness may be advantageous in space-constrained designs. Cross-manufacturer sourcing provides supply chain redundancy. All parts maintain identical compliance certifications (ROHS3, MSL 1).

Q: Are all substitute parts available in the same packaging format?

A: The KYOCERA AVX substitutes (1812GA151JAT1A and 1812GA151KAT1A) are specified in Tape & Reel (TR) packaging. The main part 1812GA151MAT1A packaging is not specified in the provided data. Confirm packaging requirements with procurement specifications before order placement.

Q: What compliance certifications apply to all listed parts?

A: All parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All carry MSL 1 (unlimited moisture sensitivity) rating, eliminating moisture-related handling restrictions.
