Substitute Part Grouping Explanation

Substitution eligibility for the 1825AC473MAT3A\SB is determined by strict equivalence in the following parameters:

• Capacitance Value: Must be 0.047 µF (no deviation)
• Voltage Rating: Must be 1000V (1kV) or higher
• Temperature Coefficient: Must be X7R (ensures identical temperature stability)
• Package / Case: Must be 1825 (4564 Metric) (ensures mechanical and electrical compatibility)
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must cover -55°C ~ 125°C minimum
• Regulatory Compliance: Must maintain ROHS3 and REACH compliance status

The substitute part 1825AC473KAT1A meets all these criteria. The primary difference is the capacitance tolerance specification (±10% versus ±20%), which represents an upgrade in precision without affecting substitutability.

Parameter Comparison

Engineering Selection Recommendations

The 1825AC473KAT1A is a direct substitute for the 1825AC473MAT3A\SB. Both parts are manufactured by KYOCERA AVX and maintain identical electrical and mechanical specifications. The substitute part offers improved capacitance tolerance (±10% versus ±20%), which may provide enhanced circuit performance in applications requiring tighter capacitance control. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Selection between these parts should be based on packaging requirements (the substitute is supplied in Tape & Reel format) and inventory availability rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can 1825AC473KAT1A replace 1825AC473MAT3A\SB in existing designs?

A: Yes. Both parts have identical capacitance values, voltage ratings, temperature coefficients, package dimensions, and operating temperature ranges. The substitute part meets all electrical and mechanical compatibility requirements for direct substitution.

Q: What is the difference between these two parts?

A: The primary difference is capacitance tolerance. The 1825AC473MAT3A\SB has ±20% tolerance, while the 1825AC473KAT1A has ±10% tolerance. The substitute provides tighter tolerance control. Packaging format also differs: the main part uses standard packaging while the substitute is supplied in Tape & Reel format.

Q: Are both parts currently available?

A: Yes. The 1825AC473MAT3A\SB has 664 pieces in stock, and the 1825AC473KAT1A has 2300 pieces in stock. Both are active production parts from KYOCERA AVX.

Q: Do these parts meet RoHS and REACH requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Can I use a substitute part with different tolerance in my circuit?

A: The tighter tolerance of the substitute part (±10%) is compatible with any application designed for the main part (±20%). The substitute will perform within the original specification range and provide additional precision.
