1808HC102MAT9A Equivalent & Substitute Parts

Part Overview

The 1808HC102MAT9A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 1000 pF, rated for 3000V (3kV), and featuring X7R temperature coefficient characteristics. This Surface Mount MLCC (Multilayer Ceramic Capacitor) in 1808 (4520 Metric) package format is designed for general-purpose applications requiring high-voltage performance across the -55°C to 125°C operating temperature range. The part maintains Active product status and is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection. Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and sourcing options while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808HC102MAT9A is determined by strict equivalence across the following critical parameters: capacitance value (1000 pF), voltage rating (3000V minimum), temperature coefficient (X7R), package format (1808 / 4520 Metric), and mounting technology (Surface Mount MLCC). All identified substitute parts maintain identical capacitance, voltage rating, temperature coefficient, and package specifications. Tolerance variations (±20% for the main part versus ±10% for substitutes) represent an upgrade path, as tighter tolerance does not compromise compatibility. Physical dimensions remain within acceptable tolerances for PCB assembly. All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and full ROHS3 compliance with MSL 1 rating, confirming regulatory and environmental compatibility with the original 1808HC102MAT9A specification. The 1808HC102KAT1A and KGM42CR73U102KY are KYOCERA AVX products offering tighter ±10% tolerance compared to the original ±20% tolerance, representing a direct upgrade path within the same manufacturer ecosystem. The VPDP302W102K1GV001E from Johanson Dielectrics Inc. provides cross-manufacturer equivalence with identical electrical specifications and maintains dimensional compatibility within acceptable PCB assembly tolerances. Selection between substitute parts should be based on packaging format availability (Cut Tape, Digi-Reel, or Tape & Reel), inventory requirements, and application-specific sourcing constraints.

Frequently Asked Questions (FAQ)

Q: Can the 1808HC102KAT1A replace the 1808HC102MAT9A directly? A: Yes. Both parts share identical capacitance (1000 pF), voltage rating (3000V), temperature coefficient (X7R), and 1808 package format. The 1808HC102KAT1A features ±10% tolerance versus ±20% for the original, representing improved performance characteristics. Both are KYOCERA AVX products with Active status and ROHS3 compliance.

Q: What is the difference between KGM42CR73U102KY and 1808HC102KAT1A? A: Both are KYOCERA AVX 1000 pF, 3000V, X7R ceramic capacitors in 1808 package with ±10% tolerance and identical electrical specifications. The primary difference is packaging format: 1808HC102KAT1A is supplied in Cut Tape (CT) & Digi-Reel format, while KGM42CR73U102KY is supplied in Tape & Reel (TR) format. KGM42CR73U102KY belongs to the KGM - HV series.

Q: Is the VPDP302W102K1GV001E from a different manufacturer compatible? A: Yes. The VPDP302W102K1GV001E from Johanson Dielectrics Inc. is electrically and mechanically equivalent with identical capacitance, voltage rating, temperature coefficient, and 1808 package format. Physical dimensions are within acceptable tolerances (4.70mm x 2.03mm versus 4.60mm x 2.00mm for the original). Cross-manufacturer substitution is valid for this specification.

Q: Does tolerance difference affect circuit performance? A: Tolerance specifications define the acceptable capacitance variation from the nominal value. The original 1808HC102MAT9A allows ±20% variation, while substitute parts with ±10% tolerance provide tighter capacitance control. Tighter tolerance does not compromise compatibility and may improve circuit performance in applications sensitive to capacitance variation.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All identified substitute parts (1808HC102KAT1A, KGM42CR73U102KY, and VPDP302W102K1GV001E) maintain ROHS3 compliance and MSL 1 rating, matching the environmental and regulatory status of the original 1808HC102MAT9A.

Q: What packaging formats are available for these substitutes? A: The 1808HC102KAT1A is available in Cut Tape (CT) & Digi-Reel format. The KGM42CR73U102KY and VPDP302W102K1GV001E are supplied in Tape & Reel (TR) format. Packaging selection depends on assembly process requirements and inventory management preferences.
