1808HC102MATBE Equivalent & Substitute Parts

Part Overview

The 1808HC102MATBE 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 in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the 1808HC102MATBE is determined by strict alignment of the following critical parameters:

Capacitance: 1000 pF (exact match required)
Voltage Rating: 3000V (3kV) minimum (exact match required)
Temperature Coefficient: X7R (exact match required)
Package / Case: 1808 (4520 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)
Moisture Sensitivity Level: 1 (exact match required)

Tolerance variation (±20% vs. ±10%) is permitted as a substitution parameter when the application circuit design accommodates tighter tolerance specifications. Physical dimension tolerances within the 1808 package specification are acceptable. All identified substitutes meet or exceed the electrical and environmental specifications of the primary part.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Selection between substitute options is based on the following engineering criteria:

KYOCERA AVX 1808HC102KAT1A and KGM42CR73U102KY offer tighter capacitance tolerance (±10%) compared to the primary part (±20%), providing improved circuit performance in applications requiring stricter capacitance control. Both parts are manufactured by KYOCERA AVX, ensuring consistent quality and supply chain alignment with the primary part manufacturer.

Johanson Dielectrics Inc. VPDP302W102K1GV001E provides the highest inventory availability and is specified for SMPS filtering applications. This part exhibits the lowest thickness profile (0.085" / 2.16mm) within the 1808 package specification, offering potential advantages in space-constrained designs.

Cal-Chip Electronics, Inc. CHV1808N3K0102MXT maintains identical tolerance (±20%) and physical dimensions to the primary part, providing direct functional equivalence with alternative supply chain sourcing.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1808HC102KAT1A for 1808HC102MATBE in my design?

A: Yes. The 1808HC102KAT1A is a direct substitute with identical electrical specifications and package dimensions. The tighter tolerance (±10% vs. ±20%) represents an upgrade that improves circuit performance without requiring design modification.

Q: What is the difference between the KYOCERA AVX and Johanson Dielectrics parts?

A: Both manufacturers provide 1000 pF, 3000V, X7R ceramic capacitors in 1808 package with ±10% tolerance. The Johanson part (VPDP302W102K1GV001E) has a slightly lower thickness profile (2.16mm vs. 2.20mm) and higher inventory availability. Electrical performance is equivalent.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification and unlimited moisture sensitivity rating (MSL 1), matching the environmental and regulatory specifications of the primary part.

Q: Can I use CHV1808N3K0102MXT as a direct replacement?

A: Yes. The CHV1808N3K0102MXT from Cal-Chip Electronics maintains identical capacitance tolerance (±20%), voltage rating, temperature coefficient, and physical dimensions as the primary part, providing direct functional equivalence.

Q: Which substitute offers the best availability?

A: The Johanson Dielectrics VPDP302W102K1GV001E part number shows the highest inventory level (115,670 pcs) among all identified substitutes, supporting rapid procurement and supply chain continuity.
