Substitute Part Grouping Explanation

Substitute parts for the 1812GC102KATME are categorized based on the following substitution criteria:

Upgrade Parts — Higher voltage rating (2.5kV or 3kV) while maintaining 1000 pF capacitance, ±10% tolerance, X7R temperature coefficient, and 1812 package. These parts provide enhanced voltage margin for the same footprint and are pin-compatible.

Parametric Equivalents — Identical electrical specifications (1000 pF, ±10%, 2000V, X7R) with different packaging formats (Cut Tape vs. Tape & Reel) or alternative KYOCERA AVX series designations. These are direct functional replacements.

Direct Substitutes from Alternative Manufacturers — Parts from YAGEO, KEMET, and Johanson Dielectrics with matching 1000 pF, ±10%, 2000V, X7R specifications in 1812 package. Minor dimensional variations exist within acceptable tolerances.

Tolerance Upgrade — KGM43FCG3D102JV offers ±5% tolerance (tighter than ±10%) at 2000V with C0G/NP0 temperature coefficient for applications requiring superior stability.

Frequently Asked Questions (FAQ)

Q: Can I use 1812HC102KAT1A or KGM43FR73U102KV as direct replacements for 1812GC102KATME?

A: Yes, both parts are pin-compatible and footprint-compatible in the 1812 package. The 3kV rating provides higher voltage margin while maintaining identical 1000 pF capacitance and ±10% tolerance. Thickness increases from 1.80mm to 2.20mm or 2.21mm respectively, which must be verified against PCB clearance constraints.

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

A: X7R provides ±15% capacitance change across -55°C to 125°C operating range. C0G/NP0 provides ±30 ppm/°C (approximately ±0.3% across the same range), offering superior stability. KGM43FCG3D102JV with C0G/NP0 is suitable for precision applications requiring tighter capacitance tolerance.

Q: Are YAGEO, KEMET, and Johanson Dielectrics parts qualified equivalents?

Electrical specifications (1000 pF, ±10%, 2000V, X7R) are identical. Minor dimensional variations exist within acceptable tolerances for 1812 package footprint.

Q: Which substitute part has the best inventory availability?

A: C1812C102KGRAC7800 (KEMET) has 60226 pieces in stock, significantly higher than other options. This part is a direct 2000V equivalent with 0.061" thickness and is ROHS3 compliant with MSL 1 rating.

Q: Can I use VPDR202W102K1GV001E in general-purpose applications?

A: Yes. Although specified for SMPS filtering, VPDR202W102K1GV001E meets all electrical and mechanical requirements for general-purpose high-voltage applications. It is ROHS3 compliant with MSL 1 rating and 1000 pF, ±10%, 2000V, X7R specifications. Note the 0.110" (2.80mm) thickness.

Q: What is the impact of thickness variation among substitute parts?

A: Thickness ranges from 0.059" (1.50mm) for CC1812KKX7RDBB102 to 0.110" (2.80mm) for 1812WC102KAT1A and VPDR202W102K1GV001E. PCB design must accommodate the selected part's maximum thickness to ensure proper component placement and clearance. Higher voltage ratings typically result in increased thickness due to dielectric material requirements.
