Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FD2J274JC is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.27 µF (exact match required)
• Tolerance: ±5% (exact match required)
• DC voltage rating: 630V (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Physical dimensions and lead spacing (exact match required)
• Termination type: PC Pins (exact match required)

The ECW-FD2J274J qualifies as a parametric equivalent based on matching all critical electrical and mechanical specifications. The presence of an AC voltage rating (141V) in the substitute part does not affect DC circuit compatibility and represents additional specification data not present in the main part listing.

Parameter Comparison

Engineering Selection Recommendations

Both ECW-FD2J274JC and ECW-FD2J274J are active production parts manufactured by Panasonic Electronic Components with identical compliance certifications. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Selection between these parts should be based on inventory availability and procurement lead times. The ECW-FD2J274J currently has higher inventory (1835 units) compared to the ECW-FD2J274JC (1026 units), making it suitable for applications requiring immediate availability. Both parts are functionally interchangeable in circuit applications requiring 0.27 µF capacitance at 630V DC with polypropylene dielectric construction.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2J274J be used as a direct replacement for ECW-FD2J274JC?

A: Yes. Both parts share identical electrical specifications (0.27 µF, ±5% tolerance, 630V DC), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), and mechanical configuration (radial through-hole, identical dimensions and lead spacing). They are parametric equivalents suitable for direct substitution in circuit designs.

Q: What is the significance of the AC voltage rating shown for ECW-FD2J274J?

A: The AC voltage rating (141V) is supplementary specification data provided for the substitute part. This does not affect compatibility in DC applications. Both parts are rated for 630V DC operation, which is the primary specification for this component category.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical dimensions (0.701" L x 0.236" W / 17.80mm x 6.00mm), maximum seated height (0.492" / 12.50mm), and lead spacing (0.591" / 15.00mm). They are mechanically interchangeable for PCB layout and assembly purposes.

Q: Do both parts meet current compliance requirements?

A: Yes. Both ECW-FD2J274JC and ECW-FD2J274J are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component procurement and use.

Q: What applications are these capacitors designed for?

A: Both parts are specified for EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT applications. The polypropylene metallized construction and 630V rating make them suitable for power conditioning and filtering circuits requiring high voltage performance.
