Temperature Coefficient: X7R (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)

Allowed variations in substitute parts:

Voltage Rating: May be equal to or higher than 1500V
Tolerance: May be ±20%, ±10%, or ±5%

Engineering Selection Recommendations

All listed substitute parts are manufactured by KYOCERA AVX and maintain active product status. All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

For direct replacement without circuit redesign, select 1812SC102MAT1A, which provides identical electrical and mechanical specifications with different packaging format (Tape & Reel).

For applications requiring improved voltage margin, select from the 2000V rated options (1812GC102KAT1A, 1812GC102MAT1A, KGM43ER73D102KV, KGM43ER73D102MV). These maintain identical physical footprint and thickness as the original part.

For maximum voltage headroom, select from the 2500V or 3000V rated options (1812WC102KAT1A, 1812HC102KAT1A, KGM43FR73U102KV, KGM43FR73U102MV). Note that 3000V variants exhibit increased thickness (0.087" to 0.110"), which may affect PCB layout clearance.

For tighter tolerance requirements, select parts with ±10% or ±5% tolerance ratings. The KGM43FCG3D102JV offers ±5% tolerance with C0G/NP0 temperature coefficient at 2000V, suitable for precision applications requiring superior temperature stability.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute?

A: Yes. Higher voltage ratings provide additional safety margin and are electrically compatible. The 1812SC102MATME operates at 1500V; substitutes rated at 2000V, 2500V, or 3000V are acceptable. Verify PCB layout accommodates any thickness increase associated with higher voltage ratings.

Q: What is the difference between tolerance ratings ±20%, ±10%, and ±5%?

A: Tolerance defines the allowable deviation from the nominal 1000 pF capacitance value. ±20% allows 800–1200 pF; ±10% allows 900–1100 pF; ±5% allows 950–1050 pF. Select tighter tolerance for precision circuits; ±20% is acceptable for general-purpose filtering and coupling applications.

Q: Are packaging format differences (Cut Tape, Tape & Reel, Digi-Reel) electrically significant?

A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical and mechanical specifications remain identical. Select based on manufacturing equipment compatibility and inventory management requirements.

Q: Why do higher voltage capacitors have greater thickness?

A: Increased voltage rating requires additional dielectric material layers to withstand higher electric fields. This results in greater physical thickness. Verify PCB clearance before substituting with higher voltage variants.

Q: Is the X7R temperature coefficient suitable for my application?

A: X7R provides ±15% capacitance variation across the -55°C to 125°C operating range. This is suitable for general-purpose applications. For precision circuits requiring superior temperature stability, consider C0G/NP0 variants such as KGM43FCG3D102JV, which provide ±0.3% per °C stability.

Q: Are all substitute parts ROHS3 and REACH compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.
