Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. Selection between substitutes depends on application voltage requirements and tolerance specifications:

For 630V applications: The original 1808CC102MATBE is the direct specification match. If unavailable, 1808AC102KAT1A (1000V) provides voltage margin with improved tolerance (±10%).

For 1000V applications: 1808AC102KAT1A and C4520X7R3A102K130KA are direct equivalents. The TDK part offers reduced thickness (0.059" vs 0.071"), which may be beneficial for space-constrained designs.

For 1500V applications: 1808SC102KAT1A is the sole option with ±10% tolerance.

For 2000V applications: Four options exist. 1808GC102KAT1A and 1808GC102MAT1A maintain standard thickness (0.071"). KGM42CR73D102KY and KGM42CR73D102MY (KGM series) offer higher inventory availability with increased thickness (0.087").

For 2500V applications: 1808WC102KAT1A is the only option, with increased thickness (0.087").

For 3000V applications: 1808HC102KAT1A and KGM42CR73U102KY are available. The KGM series part offers higher inventory (5700 vs 4597 units).

Tolerance considerations: Parts with ±10% tolerance provide tighter capacitance control. Parts with ±20% tolerance match the original specification and are suitable for general purpose applications where tolerance is non-critical.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage rated capacitor as a substitute for the 1808CC102MATBE?

A: Yes. Higher voltage ratings are acceptable substitutes provided all other parameters match: 1000 pF capacitance, X7R temperature coefficient, 1808 package, -55°C to 125°C operating range, and ROHS3 compliance. Higher voltage ratings provide additional safety margin in the circuit.

Q: What is the difference between ±10% and ±20% tolerance parts?

A: Tolerance specifies the allowable deviation from the nominal 1000 pF capacitance value. ±10% tolerance parts range from 900 pF to 1100 pF. ±20% tolerance parts range from 800 pF to 1200 pF. Select ±10% tolerance for applications requiring tighter capacitance control; select ±20% for general purpose applications where wider tolerance is acceptable.

Q: Are KYOCERA AVX and TDK Corporation parts interchangeable?

A: Yes, provided electrical and mechanical specifications match. C4520X7R3A102K130KA (TDK) is electrically equivalent to 1808AC102KAT1A (KYOCERA AVX) at 1000V. However, the TDK part has reduced thickness (0.059" vs 0.071"), which may affect PCB layout and assembly considerations.

Q: What does the KGM series designation indicate?

A: KGM series parts are KYOCERA AVX high voltage (HV) ceramic capacitors. KGM42CR73D102KY and KGM42CR73U102KY are functionally equivalent to standard 1808 series parts at 2000V and 3000V respectively, with increased thickness (0.087") and higher inventory availability.

Q: Can I substitute a part with different thickness?

A: Thickness differences must be evaluated for PCB assembly compatibility. Standard 1808 parts are 0.071" (1.80mm) thick. KGM series and higher voltage parts are 0.087" (2.20-2.21mm) thick. TDK C4520 series is 0.059" (1.50mm) thick. Verify PCB footprint and assembly equipment clearance before substitution.

Q: What packaging formats are available?

A: Substitutes are supplied in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats. Select based on production volume and assembly equipment compatibility. Tape & Reel is standard for high-volume automated assembly.
