ECW-FD2J475JC Equivalent & Substitute Parts

Part Overview

The ECW-FD2J475JC is a 4.7 µF film capacitor rated for 630V DC, manufactured by Panasonic Electronic Components. This polypropylene metallized radial capacitor is designed for EMI/RFI suppression, high-frequency switching, and high pulse applications. The part is currently active in production with 1110 units in stock. Substitute parts may be required due to inventory constraints, regional availability, or specific application requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FD2J475JC is determined by strict equivalence across the following critical parameters:

• Capacitance value: 4.7 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 type: Radial (exact match required)
• Physical dimensions and lead spacing (exact match required)
• Termination type: PC Pins (exact match required)

The ECW-FD2J475J qualifies as a parametric equivalent based on matching all critical electrical and mechanical specifications. AC voltage rating presence does not affect DC-primary applications and does not disqualify substitution.

Parameter Comparison

Engineering Selection Recommendations

Both ECW-FD2J475JC and ECW-FD2J475J are active production parts manufactured by Panasonic Electronic Components and maintain full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and application-specific requirements. The ECW-FD2J475J includes an AC voltage rating specification (141V) not present in the ECW-FD2J475JC datasheet notation, but this does not affect DC-primary circuit applications. Both parts are suitable for direct substitution in through-hole PCB assemblies requiring 4.7 µF capacitance at 630V DC with polypropylene dielectric construction.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2J475J be used as a direct replacement for ECW-FD2J475JC?

A: Yes. Both parts share identical capacitance (4.7 µF), tolerance (±5%), DC voltage rating (630V), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), mounting type (through hole), package type (radial), physical dimensions (0.996" L x 0.720" W), lead spacing (0.886"), and termination type (PC pins). They are parametric equivalents.

Q: What is the significance of the AC voltage rating on the ECW-FD2J475J?

A: The ECW-FD2J475J includes an AC voltage rating specification (141V) in its datasheet. For applications operating primarily in DC mode, this parameter does not affect substitution eligibility. The DC voltage rating of 630V remains the controlling specification for both parts.

Q: Are there any physical compatibility concerns when substituting these parts?

A: No. Both parts are identical in physical dimensions (25.30mm x 18.30mm), height (25.40mm maximum seated), and lead spacing (22.50mm). They are mechanically interchangeable in through-hole PCB designs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ECW-FD2J475JC and ECW-FD2J475J are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: Which part should be selected based on availability?

A: Selection should prioritize inventory status. The ECW-FD2J475JC has 1110 units in stock, while the ECW-FD2J475J has 937 units in stock. Both are suitable for immediate procurement.
