Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825WC472MAT3A is determined by the following mandatory parameters: identical capacitance value (4700 pF), identical package type (1825 / 4564 metric), identical temperature coefficient (X7R), identical mounting type (surface mount MLCC), and identical operating temperature range (-55°C to 125°C). Voltage rating and tolerance are the primary variables that define substitute categories.

The identified substitute parts maintain all mandatory parameters while offering variations in voltage rating and tolerance specifications:

• Voltage Rating Upgrades: Parts rated at 3000V (3kV) provide higher voltage margin than the original 2500V specification and are electrically compatible in applications where the original part operates.
• Tolerance Variations: Parts with ±10% tolerance provide tighter capacitance control compared to the original ±20% tolerance specification.

All substitute parts are manufactured by KYOCERA AVX, maintain active product status, and comply with ROHS3 and REACH requirements identical to the main part.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full compliance with ROHS3 and REACH requirements, ensuring regulatory continuity with the original 1825WC472MAT3A specification.

1825WC472KAT1A provides identical voltage rating (2500V) with improved tolerance specification (±10% versus ±20%), suitable for applications requiring tighter capacitance control while maintaining the original voltage margin.

1825HC472MAT1A and 1825HC472KAT1A both provide upgraded voltage rating (3000V versus 2500V), offering increased voltage margin for the same capacitance value and package footprint. The 1825HC472KAT1A combines the 3000V rating with ±10% tolerance for maximum specification upgrade. The 1825HC472MAT1A maintains ±20% tolerance with 3000V rating.

Selection between substitute parts depends on application voltage requirements and tolerance specifications. All parts are electrically and mechanically compatible within the stated parameters.

Frequently Asked Questions (FAQ)

Q: Can 1825HC472MAT1A or 1825HC472KAT1A be used as direct replacements for 1825WC472MAT3A?

A: Yes. Both parts maintain identical capacitance (4700 pF), package type (1825), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). The 3000V rating provides higher voltage margin than the original 2500V specification and is compatible in applications operating at or below 2500V.

Q: What is the difference between 1825WC472KAT1A and 1825WC472MAT3A?

A: Both parts share identical voltage rating (2500V), capacitance (4700 pF), and package specifications. The primary difference is tolerance: 1825WC472KAT1A provides ±10% tolerance compared to ±20% for the original part, enabling tighter capacitance control.

Q: Are there packaging differences between substitute parts?

A: Packaging format varies: 1825WC472MAT3A and 1825HC472MAT1A are supplied in Tape & Reel (TR) format, while 1825WC472KAT1A packaging is not specified and 1825HC472KAT1A is supplied in Cut Tape (CT) & Digi-Reel® format. All parts use identical 1825 package footprint and are surface-mount compatible.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All parts including the main part 1825WC472MAT3A are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity level), ensuring identical regulatory and environmental compliance.

Q: Which substitute part offers the best availability?

A: 1825HC472KAT1A has the highest inventory level at 2400 pieces, compared to 845 pieces for 1825WC472KAT1A and 629 pieces for 1825HC472MAT1A.
