Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. Selection between substitutes depends on application voltage requirements:

• 1825AA472JAT1A: Suitable for 1kV applications requiring tighter tolerance (±5%) and C0G/NP0 temperature stability. Thickness increases to 0.110" (2.80mm).

• 1825HC472KAT1A: Suitable for applications requiring 3kV voltage rating while maintaining X7R temperature coefficient and ±10% tolerance. Maintains original thickness of 0.100" (2.54mm).

• 1825WC472KAT1A: Suitable for applications requiring 2.5kV voltage rating while maintaining X7R temperature coefficient and ±10% tolerance. Maintains original thickness of 0.100" (2.54mm).

All substitutes are manufactured by KYOCERA AVX, maintain identical capacitance value, package dimensions, and operating temperature range as the original part.

Frequently Asked Questions (FAQ)

Q: Can 1825AA472JAT1A replace 1825AC472KAT3A\SB in a 1kV circuit?

A: Yes. Both parts are rated for 1000V (1kV) and share identical package dimensions and capacitance. The 1825AA472JAT1A offers improved tolerance (±5% versus ±10%) and C0G/NP0 temperature coefficient instead of X7R. Verify that the increased thickness of 0.110" (2.80mm) accommodates your PCB layout.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance change across the -55°C to 125°C operating range. C0G/NP0 provides ±30 ppm/°C, resulting in minimal capacitance variation. Selection depends on circuit requirements for capacitance stability.

Q: Can I use 1825HC472KAT1A (3kV) in place of 1825AC472KAT3A\SB (1kV)?

A: Yes. Higher voltage-rated components are electrically compatible in lower-voltage applications. The 1825HC472KAT1A maintains identical package dimensions, capacitance, and X7R temperature coefficient. Verify PCB layout compatibility.

Q: Are all substitute parts available in the same packaging options?

A: Packaging varies. The main part uses standard packaging, 1825AA472JAT1A is available in Tape & Reel (TR), and 1825HC472KAT1A is available in Cut Tape (CT) & Digi-Reel®. Confirm packaging requirements with your procurement process.

Q: Do all parts meet the same compliance standards?

A: Yes. All listed parts are ROHS3 Compliant, REACH Unaffected, and classified as ECCN EAR99. Moisture Sensitivity Level is 1 (Unlimited) for all parts.
