1812SA151MAT1A\SB Equivalent & Substitute Parts

Part Overview

The 1812SA151MAT1A\SB is a 150 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 1500V (1.5kV) operation with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) in 1812 (4532 Metric) package is designed for general purpose high voltage applications and maintains active product status with 1113 units currently in stock.

Substitute parts are identified when design requirements permit higher voltage ratings, improved tolerance specifications, or alternative manufacturer sourcing while maintaining identical capacitance values and compatible package dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812SA151MAT1A\SB is determined by the following criteria:

Mandatory Compatibility Parameters:

• Capacitance value: 150 pF (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Temperature Coefficient: C0G, NP0 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)

Allowable Variation Parameters:

• Voltage Rating: Equal to or greater than 1500V
• Tolerance: Equal to or tighter than ±20%
• Manufacturer: Different manufacturers permitted
• RoHS / REACH Compliance: Must maintain ROHS3 Compliant and REACH Unaffected status

The three identified substitute parts meet all mandatory compatibility requirements while offering enhanced electrical performance through higher voltage ratings and improved tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full ROHS3 compliance with REACH Unaffected designation, ensuring regulatory compatibility with the original 1812SA151MAT1A\SB specification.

1812GA151JAT1A (KYOCERA AVX): Offers 2000V rating with ±5% tolerance improvement. Maintains KYOCERA AVX manufacturer continuity while providing enhanced voltage margin and tighter capacitance tolerance.

1812GA151KAT1A (KYOCERA AVX): Provides 2000V rating with ±10% tolerance. Represents a balanced upgrade path within the KYOCERA AVX product line with moderate voltage headroom.

C4532C0G3F151K160KA (TDK Corporation): Delivers maximum voltage rating at 3000V with ±10% tolerance. Suitable for applications requiring significant voltage derating margin or cross-manufacturer qualification. Highest inventory availability at 24949 units.

Frequently Asked Questions (FAQ)

Q: Can 1812GA151JAT1A replace 1812SA151MAT1A\SB in all applications?

A: Yes, provided the circuit design accommodates the 2000V rating. The substitute maintains identical capacitance, temperature coefficient, package dimensions, and operating temperature range. The ±5% tolerance is tighter than the original ±20%, ensuring improved capacitance accuracy.

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

A: All parts use the 1812 (4532 Metric) package with identical length (0.181" / 4.60mm) and width (0.126" / 3.20mm). Thickness varies: main part at 0.057" (1.45mm), KYOCERA AVX substitutes at 0.087" (2.20mm), and TDK substitute at 0.071" (1.80mm). Verify PCB layout clearance before substitution.

Q: Are there manufacturing differences between KYOCERA AVX and TDK versions?

A: Both manufacturers produce ROHS3 compliant, REACH Unaffected components with identical electrical specifications for capacitance, temperature coefficient, and operating range. Manufacturing processes and internal construction may differ, but functional performance in the specified operating envelope is equivalent.

Q: Which substitute offers the best voltage safety margin?

A: C4532C0G3F151K160KA (TDK) provides 3000V rating, offering the highest voltage derating capability. For applications with 1500V nominal requirements, this part provides 2x voltage margin.

Q: Can substitutes be mixed in the same assembly?

A: Yes. All substitutes meet identical electrical and mechanical compatibility criteria. Mixed sourcing is permissible if supply chain or cost considerations require it, provided all parts maintain ROHS3 and REACH compliance status.
