Engineering Selection Recommendations

All substitute parts listed maintain ROHS3 compliance, MSL 1 rating, and active product status. Selection between substitutes depends on application-specific requirements:

KYOCERA AVX KGM43FCG3D102JV offers the closest electrical match to the original part, maintaining C0G/NP0 temperature coefficient with improved tolerance (±5%) and elevated voltage rating (2000V). This part is recommended for applications requiring stable capacitance across temperature variations.

KYOCERA AVX 1812GC102MAT1A provides the highest inventory availability (14533 Pcs) with matching tolerance (±20%) to the original part and X7R temperature coefficient, suitable for general purpose applications where temperature stability is less critical.

KEMET C1812C102KGRAC7800 offers the lowest profile thickness (0.061") with X7R temperature coefficient and 2000V rating, providing space optimization benefits in compact designs with high inventory availability (60226 Pcs).

KEMET C1812C102KHRAC7800 delivers the highest voltage rating (3000V) for applications requiring maximum voltage margin, with X7R temperature coefficient and standard thickness profile.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than the original 1812SA102MAT1A?

A: Yes. All listed substitutes with voltage ratings of 2000V, 2500V, or 3000V are electrically compatible with applications designed for 1500V operation. Higher voltage ratings provide additional safety margin and do not degrade performance in lower voltage applications.

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

A: C0G/NP0 provides superior temperature stability with minimal capacitance variation across the -55°C to 125°C operating range. X7R offers acceptable stability for general purpose applications with slightly greater capacitance variation. Both maintain the same operating temperature range specified for the original part.

Q: Are KYOCERA AVX and KEMET parts interchangeable in the same PCB footprint?

A: Yes. All substitute parts use the identical 1812 (4532 Metric) package form factor with the same length (0.181" / 4.60mm) and width (0.126" / 3.20mm). Thickness variations exist but do not affect PCB mounting compatibility. Verify PCB clearance for parts with maximum thickness of 0.110" (1812WC102KAT1A).

Q: Which substitute offers the best tolerance specification?

A: KGM43FCG3D102JV provides ±5% tolerance, the tightest specification among all substitutes. For applications requiring tolerance matching the original ±20%, 1812GC102MAT1A is the direct equivalent.

Q: What packaging formats are available for these substitutes?

A: KYOCERA AVX parts are supplied in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats. KEMET parts are supplied in Cut Tape (CT) & Digi-Reel® format. Verify packaging requirements with procurement specifications before ordering.
