Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Upgrade Substitutes maintain or improve upon the main part specifications while preserving core electrical parameters (capacitance, temperature coefficient, package). These parts offer tighter tolerance (±10% vs ±20%), higher voltage ratings (2.5kV or 3kV), or alternative series designations from the same manufacturer or qualified cross-manufacturer sources.

Parametric Equivalents match the main part exactly in capacitance, voltage rating, temperature coefficient, and tolerance. These parts differ only in packaging format (Tape & Reel vs Cut Tape) or internal series designation but maintain identical electrical performance.

Key substitution parameters:

• Capacitance: 1000 pF (fixed)
• Voltage Rating: 2000V minimum (upgrades to 2.5kV or 3kV acceptable)
• Temperature Coefficient: X7R (upgrades to C0G/NP0 acceptable for improved stability)
• Tolerance: ±20% (upgrades to ±10% or ±5% acceptable)
• Package: 1812 (4532 Metric) surface mount
• Operating Temperature: -55°C to 125°C (minimum requirement)

Parameter Comparison

Engineering Selection Recommendations

Direct Upgrade Path (Recommended for New Designs): 1812GC102KAT1A or KGM43ER73D102KV provide tighter ±10% tolerance while maintaining 2000V rating and X7R stability. Both are ROHS3 compliant with MSL 1 rating.

Higher Voltage Margin Applications: 1812HC102KAT1A (3kV) or KGM43FR73U102KV (3kV) offer increased voltage headroom for designs requiring enhanced reliability. Note increased thickness (0.087" to 0.110") may affect PCB layout.

Precision Applications: KGM43FCG3D102JV provides ±5% tolerance with C0G/NP0 temperature coefficient for circuits requiring superior capacitance stability across temperature extremes.

Cross-Manufacturer Alternative: C1812C102KGRAC7800 (KEMET) is electrically equivalent with ±10% tolerance and 2000V rating. Thinner profile (0.061") may benefit space-constrained layouts. All candidates maintain ROHS3 compliance and MSL 1 rating.

Parametric Equivalents (Direct Replacement): 1812GC102MAT1A and KGM43ER73D102MV match the main part exactly in all electrical specifications and tolerance. Selection between these and the main part depends on packaging availability and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1812GC102KAT1A for 1812GC102MATME? A: Yes. Both parts share identical capacitance (1000 pF), voltage rating (2000V), temperature coefficient (X7R), and package (1812). The substitute offers improved tolerance (±10% vs ±20%), making it suitable for applications where tighter capacitance control is beneficial.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R provides ±15% capacitance variation across -55°C to 125°C. C0G/NP0 offers superior stability with ±0.3% variation. Select C0G/NP0 (KGM43FCG3D102JV) for precision timing or filtering circuits; X7R is adequate for general-purpose applications.

Q: Can I use a 3kV-rated part in place of a 2kV-rated part? A: Yes. Higher voltage ratings (1812HC102KAT1A at 3kV, KGM43FR73U102KV at 3kV) are direct upgrades and provide additional safety margin. Verify PCB layout accommodates increased thickness if applicable.

Q: Does packaging format affect electrical performance? A: No. Cut Tape (CT), Digi-Reel, and Tape & Reel (TR) formats are packaging only and do not alter electrical specifications. Selection depends on assembly equipment and inventory management requirements.

Q: Are all listed parts ROHS3 compliant? A: Yes. All parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.

Q: What is the thickness impact of upgrading to higher voltage ratings? A: 2000V parts measure 0.071" (1.80mm). 2.5kV parts measure 0.110" (2.80mm). 3kV parts measure 0.087" (2.21mm). Verify PCB stackup and component clearance before selecting higher voltage alternatives.

Q: Can I use KEMET C1812C102KGRAC7800 as a direct replacement? A: Yes. The KEMET part matches KYOCERA AVX specifications (1000 pF, ±10%, 2000V, X7R, 1812 package). Cross-manufacturer substitution is valid when electrical and mechanical parameters align. Verify supplier qualification per your procurement standards.
