SR217A271KAR Equivalent & Substitute Parts

Part Overview

The SR217A271KAR is a 270 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 500V with C0G/NP0 temperature coefficient and ±10% tolerance. This radial through-hole component is part of the SkyCap® SR series and maintains Active product status. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, design flexibility, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

• Capacitance Match: Exact 270 pF value required
• Voltage Rating: Substitute must meet or exceed 500V minimum
• Temperature Coefficient: C0G/NP0 required for temperature stability
• Tolerance: ±5% or better acceptable (tighter than ±10% original)
• Mounting & Package: Through-hole radial configuration with kinked formed leads
• Operating Temperature: -55°C to 125°C range maintained
• Compliance: ROHS3 compliant, REACH unaffected

The FK26C0G2J271JN000 qualifies as a substitute based on these parameters, with improved voltage rating (630V) and tighter tolerance (±5%).

Engineering Selection Recommendations

SR217A271KAR is the preferred selection for new designs due to Active product status and full manufacturer support. This component is suitable for applications requiring 500V rated ceramic capacitors with stable C0G/NP0 characteristics.

FK26C0G2J271JN000 serves as a functional equivalent for existing designs or applications where higher voltage margin (630V) and tighter tolerance (±5%) provide design benefits. However, this part carries "Not For New Designs" status, limiting its use to legacy system maintenance or retrofit applications. Physical dimensions differ slightly (5.50mm × 4.60mm vs. 5.08mm × 3.18mm), requiring PCB layout verification before substitution.

Both parts maintain identical electrical performance within their respective tolerance bands and comply with ROHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can FK26C0G2J271JN000 replace SR217A271KAR in all applications?

A: Electrical substitution is valid based on matching capacitance, temperature coefficient, and exceeding voltage requirements. Physical dimensions differ slightly; PCB layout must accommodate the larger case size (5.50mm × 4.60mm vs. 5.08mm × 3.18mm) and verify lead spacing compatibility (5.00mm vs. 5.08mm).

Q: What is the significance of the "Not For New Designs" status on FK26C0G2J271JN000?

A: This designation indicates the manufacturer does not recommend this part for new product development. It remains available for existing designs and maintenance purposes but should not be selected for new applications. SR217A271KAR is the appropriate choice for new designs.

Q: Are tolerance differences between ±10% and ±5% critical for substitution?

A: The FK26C0G2J271JN000 offers tighter tolerance (±5%), which is superior to the original ±10% specification. This provides improved capacitance accuracy and is acceptable for substitution in applications where the original tolerance was adequate.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SR217A271KAR and FK26C0G2J271JN000 are ROHS3 compliant and REACH unaffected, maintaining identical regulatory compliance.

Q: What is the voltage rating advantage of the substitute part?

A: FK26C0G2J271JN000 is rated for 630V compared to SR217A271KAR at 500V. This 26% higher voltage rating provides additional safety margin in applications operating near the original 500V specification.
