1808HC102MAT1A Equivalent & Substitute Parts

Part Overview

The 1808HC102MAT1A is a 1000 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated for 3000V (3kV) operation with X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1808 (4520 Metric) package is designed for general-purpose high-voltage applications. The part is currently active and in stock. Substitute parts are identified to address packaging preferences, tolerance improvements, or alternative manufacturer sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the 1808HC102MAT1A are classified into two categories based on allowed electrical and mechanical parameters:

Upgrade Substitutes — Parts with improved tolerance (±10% vs. ±20%) while maintaining all other critical parameters: capacitance (1000 pF), voltage rating (3000V), temperature coefficient (X7R), package (1808), and operating temperature range (-55°C to 125°C). These parts are direct functional upgrades suitable for applications requiring tighter capacitance tolerance.

Parametric Equivalent — Parts matching the original tolerance (±20%) and all electrical specifications. These provide alternative sourcing from different manufacturers while preserving the exact electrical performance envelope.

Substitution eligibility is determined by:

Identical capacitance value (1000 pF)
Identical or superior voltage rating (3000V minimum)
Identical temperature coefficient (X7R)
Identical package footprint (1808 / 4520 Metric)
Compatible operating temperature range (-55°C to 125°C)
RoHS3 compliance and MSL 1 rating

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance with MSL 1 rating, ensuring regulatory and environmental compatibility with the original 1808HC102MAT1A.

For applications where capacitance tolerance is non-critical, the parametric equivalent CHV1808N3K0102MXT from Cal-Chip Electronics provides identical electrical specifications and mechanical footprint with the same ±20% tolerance as the original part.

For applications requiring improved capacitance accuracy, upgrade substitutes 1808HC102KAT1A, KGM42CR73U102KY, C1808C102KHRAC7800, CC1808KKX7REBB102, and VPDP302W102K1GV001E all offer ±10% tolerance while maintaining 3000V rating, X7R temperature coefficient, and 1808 package compatibility. Dimensional variations across these parts remain within acceptable tolerances for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with ±10% tolerance in place of the original ±20% part?

A: Yes. The ±10% tolerance substitutes represent an improvement in capacitance accuracy and are electrically compatible. They will perform within tighter specifications than the original part.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within the 1808 package specification. Length ranges from 0.177" to 0.185" (4.50mm to 4.70mm) and thickness from 0.085" to 0.087" (2.15mm to 2.21mm). These variations are within standard PCB assembly tolerances and do not affect footprint compatibility.

Q: Which substitute part should I select if packaging format matters?

A: The original 1808HC102MAT1A is supplied in Tape & Reel (TR) format. Substitute 1808HC102KAT1A is available in Cut Tape (CT) & Digi-Reel format. All other substitutes are supplied in Tape & Reel format. Verify packaging requirements with your procurement process.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental and regulatory status.

Q: Can I mix different manufacturers' parts in the same design?

A: Yes. All substitute parts meet identical electrical specifications (1000 pF, 3000V, X7R, -55°C to 125°C) and package requirements (1808 / 4520 Metric). Cross-manufacturer substitution is electrically and mechanically valid.
