Engineering Selection Recommendations
Selection of substitute parts depends on circuit voltage requirements and tolerance specifications:
For 630V applications with ±20% tolerance: The original 1808CC102MAT1A remains the baseline specification. No substitution is required unless packaging format or inventory constraints necessitate alternatives.
For 1000V (1kV) applications: Use 1808AC102KAT1A (KYOCERA AVX, ±10% tolerance) or C4520X7R3A102K130KA (TDK Corporation, ±10% tolerance). Both provide voltage margin above 630V with improved tolerance. The TDK part features reduced thickness (0.059" vs 0.071"), which may affect PCB layout considerations.
For 1500V (1.5kV) applications: Use 1808SC102KAT1A (KYOCERA AVX, ±10% tolerance, Tape & Reel packaging).
For 2000V (2kV) applications: Four options are available:
- 1808GC102KAT1A (±10% tolerance, Cut Tape & Digi-Reel®, 0.071" thickness)
- 1808GC102MAT1A (±20% tolerance, Cut Tape & Digi-Reel®, 0.071" thickness, highest inventory at 6100 Pcs)
- KGM42CR73D102KY (±10% tolerance, Tape & Reel, 0.087" thickness, KGM-HV series, highest inventory at 9025 Pcs)
- KGM42CR73D102MY (±20% tolerance, Tape & Reel, 0.087" thickness, KGM-HV series)
For 2500V (2.5kV) applications: Use 1808WC102KAT1A (KYOCERA AVX, ±10% tolerance, Tape & Reel packaging, 0.087" thickness).
For 3000V (3kV) applications: Two options are available:
- 1808HC102KAT1A (KYOCERA AVX, ±10% tolerance, Cut Tape & Digi-Reel®, 0.087" thickness)
- KGM42CR73U102KY (KYOCERA AVX KGM-HV series, ±10% tolerance, Tape & Reel, 0.087" thickness, highest inventory at 5700 Pcs)
All substitute parts maintain ROHS3 compliance, MSL 1 rating, and X7R temperature coefficient across the -55°C to 125°C operating range. Thickness variations (0.071" to 0.087") must be verified against PCB assembly constraints and reflow profile compatibility.
Frequently Asked Questions (FAQ)
Q: Can I use a higher voltage-rated capacitor as a direct substitute? A: Yes. Higher voltage ratings provide increased design margin and are electrically compatible. The 1000 pF capacitance and X7R temperature coefficient remain constant. Verify PCB layout clearance, as some higher-voltage parts have increased thickness (0.087" vs 0.071").
Q: What is the difference between ±10% and ±20% tolerance? A: Tolerance specifies the allowable deviation from the nominal 1000 pF value. ±10% tolerance (900–1100 pF) is tighter than ±20% tolerance (800–1200 pF). Select ±10% for applications requiring precise capacitance values; ±20% is acceptable for general-purpose filtering and coupling applications.
Q: Are KYOCERA AVX and TDK Corporation parts interchangeable? A: Yes, provided all other parameters match (capacitance, voltage, tolerance, package, temperature coefficient). The C4520X7R3A102K130KA from TDK is electrically equivalent to KYOCERA AVX 1808AC102KAT1A. Note the TDK part has reduced thickness (0.059" vs 0.071"), which may affect PCB assembly height constraints.
Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging? A: Both are surface-mount packaging formats suitable for automated assembly. Tape & Reel is standard reel packaging for high-volume production. Cut Tape & Digi-Reel® offers flexibility for lower-volume or mixed-component orders. Electrical performance is identical; selection depends on procurement and assembly requirements.
Q: Can I substitute 1808GC102MAT1A (2kV, ±20%) for the original 1808CC102MAT1A (630V, ±20%)? A: Yes. Both parts have identical tolerance (±20%) and maintain the same 1000 pF capacitance and 1808 package. The 2kV rating provides higher voltage margin. Verify PCB layout compatibility, as the 1808GC102MAT1A is available in Cut Tape & Digi-Reel® packaging format.
Q: Which substitute offers the best inventory availability? A: KGM42CR73D102KY (2kV, ±10%, KYOCERA AVX KGM-HV series) has the highest inventory at 9025 Pcs. For 3kV applications, KGM42CR73U102KY offers 5700 Pcs. For 2kV with ±20% tolerance, 1808GC102MAT1A provides 6100 Pcs.
Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level, matching the original 1808CC102MAT1A specification.
