Substitute Part Grouping Explanation

Substitution is determined by three core criteria: capacitance value, tolerance, temperature coefficient, and package compatibility. All substitute parts maintain 1000 pF ±10% capacitance with X7R temperature coefficient in the 1808 (4520 Metric) package. Substitutes are grouped by voltage rating upgrade capability and manufacturer variation.

Parametric Equivalent: Parts with identical electrical specifications (1500V rating) but different packaging or manufacturer codes.

Upgrade Substitutes: Parts with higher voltage ratings (2000V, 2500V, 3000V) that maintain all other electrical parameters. These provide enhanced voltage margin while preserving capacitance, tolerance, and temperature stability.

Cross-Manufacturer Substitutes: Parts from KEMET, TDK Corporation, and Johanson Dielectrics Inc. that meet identical electrical and mechanical specifications within the 1808 package footprint.

Engineering Selection Recommendations

All listed parts are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between equivalent and substitute parts depends on circuit voltage margin requirements and PCB layout constraints.

For direct replacement with identical voltage rating, 1808SC102KAT1A (KYOCERA AVX) provides parametric equivalence with higher inventory availability (5443 pcs vs. 954 pcs).

For applications requiring voltage margin upgrade, KYOCERA AVX offers a complete series: 1808GC102KAT1A (2000V), 1808WC102KAT1A (2500V), and 1808HC102KAT1A (3000V). The KGM series (KGM42CR73D102KY at 2000V, KGM42CR73U102KY at 3000V) provides alternative KYOCERA AVX sourcing with higher inventory depth.

Cross-manufacturer options include TDK Corporation C4520X7R3D102K130KA (2000V, 95140 pcs available), KEMET C1808C102KGRAC7800 (2000V, 3100 pcs), and Johanson Dielectrics Inc. VPDP series (VPDP202W102K1GV001E at 2000V with 87058 pcs, VPDP302W102K1GV001E at 3000V with 115670 pcs).

Thickness variation exists across manufacturers: TDK offers the thinnest profile at 0.059" (1.50mm), while Johanson Dielectrics reaches 0.085" (2.16mm). Verify PCB assembly clearance requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can 1808SC102KAT1A replace 1808SC102KATME directly?

A: Yes. Both parts are parametric equivalents with identical 1000 pF ±10% capacitance, 1500V rating, X7R temperature coefficient, and 1808 package. The difference is packaging format (Cut Tape & Digi-Reel vs. standard) and inventory source. Electrical performance is identical.

Q: What is the difference between KYOCERA AVX standard series and KGM series?

A: Both are KYOCERA AVX products with identical electrical specifications. The KGM series (KGM42CR73D102KY, KGM42CR73U102KY) is designated as KGM - HV (High Voltage) and offers higher inventory availability. Electrical parameters, package dimensions, and compliance certifications are equivalent.

Q: Can I use a 2000V rated part in place of the 1500V original?

A: Yes, provided circuit design permits. Higher voltage-rated parts (2000V, 2500V, 3000V) maintain identical capacitance, tolerance, and temperature coefficient while providing additional voltage margin. Verify PCB layout accommodates any thickness variations. TDK C4520X7R3D102K130KA is the thinnest option at 0.059" (1.50mm).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronics manufacturing.

Q: What is the difference between VPDP202W102K1GV001E and VPDP302W102K1GV001E?

A: Both are Johanson Dielectrics Inc. HVS-PME series parts with identical 1000 pF ±10% capacitance and X7R temperature coefficient in 1808 package. VPDP202W102K1GV001E is rated 2000V, while VPDP302W102K1GV001E is rated 3000V. Both have 0.085" (2.16mm) maximum thickness and are optimized for SMPS filtering applications.

Q: Does package thickness affect PCB assembly?

A: Yes. Thickness ranges from 0.059" (1.50mm) for TDK to 0.087" (2.21mm) for KYOCERA AVX KGM series. Verify clearance with component placement equipment and adjacent board features before substitution. Thinner parts may offer better clearance in space-constrained designs.

Q: Which substitute offers the best inventory availability?

A: Johanson Dielectrics Inc. VPDP302W102K1GV001E (3000V) has the highest inventory at 115,670 pcs, followed by TDK C4520X7R3D102K130KA (2000V) at 95,140 pcs. Both provide substantial supply security for high-volume applications.
