Engineering Selection Recommendations

For New Designs: The RDE5C1H390J0M1H03A (Murata Electronics) is the recommended substitute for new design implementations. This part maintains active product status, ensuring long-term availability and manufacturer support. It meets all electrical and mechanical compatibility requirements with the K390J15C0GF53L2 and carries ROHS3 compliance and REACH unaffected status.

For Existing Production or Legacy Support: The FK18C0G1H390JN020 and FK28C0G1H390JN000 (both TDK Corporation) are viable substitutes for applications where the K390J15C0GF53L2 is unavailable. Both parts are marked "Not For New Designs," indicating they are suitable for replacement in existing systems but should not be selected for new product development. Lead spacing differences must be verified against PCB layout requirements: FK18C0G1H390JN020 uses 0.098" (2.50mm) spacing, while FK28C0G1H390JN000 uses 0.197" (5.00mm) spacing.

Compliance Verification: All substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99, matching the regulatory status of the original part.

Frequently Asked Questions (FAQ)

Q: Can FK18C0G1H390JN020 be used as a direct replacement for K390J15C0GF53L2?

A: FK18C0G1H390JN020 is electrically equivalent with matching capacitance (39 pF), voltage rating (50V), tolerance (±5%), and temperature coefficient (C0G/NP0). However, lead spacing differs: FK18C0G1H390JN020 has 0.098" (2.50mm) spacing matching the original part, while physical dimensions vary slightly (height 0.217" vs. 0.220"). Verify PCB layout compatibility before substitution.

Q: What is the difference between FK28C0G1H390JN000 and FK18C0G1H390JN020?

A: Both are TDK Corporation radial ceramic capacitors with identical electrical specifications. The primary difference is lead spacing: FK28C0G1H390JN000 uses 0.197" (5.00mm) spacing, while FK18C0G1H390JN020 uses 0.098" (2.50mm) spacing. Select based on PCB hole pattern requirements.

Q: Why is RDE5C1H390J0M1H03A recommended for new designs?

A: RDE5C1H390J0M1H03A maintains active product status, indicating ongoing manufacturer support and availability. The TDK alternatives (FK18C0G1H390JN020 and FK28C0G1H390JN000) are marked "Not For New Designs," limiting their suitability for long-term production applications.

Q: Are there packaging differences between substitute parts?

A: Yes. K390J15C0GF53L2 and TDK parts (FK18C0G1H390JN020, FK28C0G1H390JN000) are supplied in Bulk packaging. RDE5C1H390J0M1H03A is supplied in Cut Tape (CT) packaging. Verify procurement and assembly process compatibility with your supply chain requirements.

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

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99, matching the regulatory requirements of the K390J15C0GF53L2.

Q: What should I verify before implementing a substitute part?

A: Confirm PCB layout compatibility with lead spacing (0.098" or 0.197"), verify component height clearance (range 0.217" to 0.236"), and validate that your assembly process accommodates the lead style (straight vs. formed leads - kinked). Electrical specifications are equivalent across all parts.
