1812GC331KATME Equivalent & Substitute Parts

Part Overview

The 1812GC331KATME is a 330 pF ceramic capacitor rated for 2000V (2kV) with X7R temperature coefficient, manufactured by KYOCERA AVX in 1812 (4532 Metric) surface mount package. This component is Active status and ROHS3 compliant. Substitute parts are identified when equivalent capacitance and tolerance values are maintained across the same package footprint, with allowance for higher voltage ratings and alternative temperature coefficients that meet or exceed the original specifications.

Substitute Part Grouping Explanation

Substitution for the 1812GC331KATME is determined by the following criteria:

• Capacitance value must remain 330 pF ±10%
• Package footprint must be 1812 (4532 Metric) surface mount
• Voltage rating must be equal to or greater than 2000V
• Temperature coefficient may differ (X7R, C0G, or NP0 acceptable)
• Operating temperature range must cover -55°C ~ 125°C
• RoHS3 compliance and MSL 1 rating required

Two substitute parts meet these criteria with upgraded voltage ratings of 3000V (3kV), providing enhanced performance margin in high-voltage applications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are Active status components with ROHS3 compliance and REACH unaffected designation, meeting regulatory requirements equivalent to the main part.

The 1812HA331KAT1A (KYOCERA AVX) provides a direct manufacturer upgrade path with identical footprint dimensions (4.60mm x 3.20mm length and width) and increased voltage rating to 3000V. Temperature coefficient changes from X7R to C0G/NP0, offering improved temperature stability characteristics.

The C4532C0G3F331K250KA (TDK Corporation) offers the same 3000V voltage rating and C0G/NP0 temperature coefficient with slightly different physical dimensions (4.50mm x 3.20mm length and width, 2.80mm maximum thickness versus 2.20mm for the KYOCERA AVX upgrade). Both substitute parts maintain the same capacitance, tolerance, and operating temperature range as the original component.

Frequently Asked Questions (FAQ)

Q: Can the 1812HA331KAT1A directly replace the 1812GC331KATME?

A: Yes. Both parts share identical 1812 (4532 Metric) package footprint and land pattern dimensions (4.60mm x 3.20mm). The 1812HA331KAT1A provides higher voltage rating (3000V versus 2000V) with the same capacitance value and tolerance. Temperature coefficient differs (C0G/NP0 versus X7R), which may affect circuit performance in temperature-sensitive applications.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance change across the -55°C to 125°C operating range. C0G/NP0 provides superior temperature stability with ±30 ppm/°C drift. Selection depends on circuit requirements for capacitance stability over temperature.

Q: Can the C4532C0G3F331K250KA (TDK) be used instead of the KYOCERA AVX parts?

A: Yes. The TDK part meets all electrical specifications (330 pF, ±10%, 3000V, C0G/NP0, -55°C to 125°C). Physical dimensions differ slightly (4.50mm x 3.20mm x 2.80mm maximum thickness). Verify PCB layout accommodates the 0.10mm difference in maximum thickness before implementation.

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

A: The 1812HA331KAT1A and C4532C0G3F331K250KA are both supplied in Tape & Reel (TR) format. Confirm packaging requirements for your assembly process.

Q: Do substitute parts maintain RoHS3 and REACH compliance?

A: Yes. Both substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original 1812GC331KATME component.
