1825WC472KATME Equivalent & Substitute Parts

Part Overview

The 1825WC472KATME is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 4700 pF, rated voltage of 2500V (2.5kV), and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1825 package (4564 Metric) is designed for general-purpose applications requiring stable performance across the -55°C to 125°C operating temperature range. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative equivalent and substitute parts are available to support design flexibility, inventory optimization, and voltage requirement variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1825WC472KATME is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Capacitance value: 4700 pF
• Tolerance: ±10%
• Temperature Coefficient: X7R
• Package / Case: 1825 (4564 Metric)
• Physical dimensions: 0.177" L x 0.252" W (4.50mm x 6.40mm)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C to 125°C

Voltage Rating Consideration: The rated voltage is not a limiting factor for substitution. Parts with equal or higher voltage ratings are functionally equivalent, as they maintain all other electrical and mechanical specifications while providing equal or greater voltage capability.

Identified Substitute Parts:

1. 1825HC472KAT1A (Upgrade Substitute) – Rated voltage 3000V (3kV), all other parameters identical to main part
2. 1825WC472KAT1A (Parametric Equivalent) – Rated voltage 2500V (2.5kV), all parameters identical to main part

Parameter Comparison

Engineering Selection Recommendations

All three parts—1825WC472KATME, 1825HC472KAT1A, and 1825WC472KAT1A—are active production components from KYOCERA AVX with ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts should be based on circuit voltage requirements and inventory availability.

1825WC472KATME and 1825WC472KAT1A are direct parametric equivalents, both rated at 2500V (2.5kV). These are suitable for applications with voltage requirements up to 2500V.

1825HC472KAT1A provides an upgrade path with a 3000V (3kV) voltage rating while maintaining identical electrical and mechanical specifications. This part is appropriate for applications requiring higher voltage margin or operating in circuits with voltage transients approaching 2500V.

All three parts maintain identical capacitance, tolerance, temperature coefficient, package dimensions, and thermal operating range, ensuring direct functional interchangeability within their respective voltage ratings.

Frequently Asked Questions (FAQ)

Q: Can 1825HC472KAT1A replace 1825WC472KATME in any application?

A: Yes. The 1825HC472KAT1A is a direct substitute with identical electrical and mechanical specifications except for a higher voltage rating (3000V vs. 2500V). It is functionally equivalent and can be used in any circuit designed for the 1825WC472KATME.

Q: What is the difference between 1825WC472KATME and 1825WC472KAT1A?

A: These are parametric equivalents with identical specifications. Both are rated at 2500V (2.5kV) with 4700 pF capacitance, ±10% tolerance, X7R temperature coefficient, and 1825 package. The difference lies in packaging format and inventory availability.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the same 1825 (4564 Metric) surface-mount package with identical physical dimensions (0.177" L x 0.252" W, 4.50mm x 6.40mm) and maximum thickness (0.100" / 2.54mm). They are directly interchangeable on PCB layouts.

Q: Which part should I select for a 2500V application?

A: Either 1825WC472KATME or 1825WC472KAT1A are appropriate for 2500V applications, as both are rated at exactly 2500V. Selection should be based on packaging availability and inventory status.

Q: Is the higher voltage rating of 1825HC472KAT1A beneficial for 2500V circuits?

A: The 3000V rating of 1825HC472KAT1A provides additional voltage margin above the 2500V circuit requirement. This can be beneficial in applications with voltage transients or where design margin is desired, though it is not required for standard 2500V operation.

Q: Are all parts RoHS compliant?

A: Yes. All three parts—1825WC472KATME, 1825HC472KAT1A, and 1825WC472KAT1A—are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.
