ECW-FD2J335JC Equivalent & Substitute Parts

Part Overview

The ECW-FD2J335JC is a 3.3 µF film capacitor rated for 630V DC, manufactured by Panasonic Electronic Components. This radial through-hole component utilizes polypropylene (PP) metallized dielectric technology and is designed for applications requiring EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT performance. The part is currently active in production with ROHS3 compliance and maintains robust inventory availability. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FD2J335JC is determined by strict equivalence across the following critical parameters:

• Capacitance value: 3.3 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)
• Series family: ECW-F(D) (exact match required)
• Compliance certifications: ROHS3 Compliant (exact match required)

The ECW-FD2J335J qualifies as a parametric equivalent under these criteria. Both parts share identical electrical specifications, physical form factors, and regulatory compliance status within the ECW-F(D) series.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FD2J335JC and ECW-FD2J335J maintain active product status with ROHS3 compliance certification. Selection between these parts should be based on application-specific AC voltage requirements and inventory availability. The ECW-FD2J335J includes an AC voltage rating of 141V, whereas the ECW-FD2J335JC does not specify an AC rating. For applications requiring AC voltage operation, the ECW-FD2J335J provides explicit AC rating documentation. Both parts are suitable for DC-dominant applications at 630V. Inventory levels favor the ECW-FD2J335J with 1498 units available compared to 695 units for the ECW-FD2J335JC.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2J335J be used as a direct replacement for ECW-FD2J335JC?

A: Yes, for applications where AC voltage operation is not required. Both parts share identical DC voltage ratings (630V), capacitance (3.3 µF), tolerance (±5%), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), physical dimensions, and lead spacing. Both are ROHS3 compliant and belong to the ECW-F(D) series.

Q: What is the difference between ECW-FD2J335JC and ECW-FD2J335J?

A: The primary difference is the AC voltage rating specification. The ECW-FD2J335J includes an AC rating of 141V, while the ECW-FD2J335JC does not specify an AC rating. All other electrical and mechanical parameters are identical.

Q: Are these parts interchangeable in PCB layouts?

A: Yes. Both parts use identical radial through-hole packaging with the same physical dimensions (25.30mm x 15.30mm), height (22.20mm), and lead spacing (22.50mm). PCB footprints and mounting requirements are identical.

Q: Which part should I select for new designs?

A: Selection depends on application requirements. For DC-only applications at 630V, either part is suitable. For applications requiring AC voltage operation, the ECW-FD2J335J with its specified 141V AC rating is the appropriate choice. Consider inventory availability and lead times when making procurement decisions.

Q: Are both parts RoHS compliant?

A: Yes. Both ECW-FD2J335JC and ECW-FD2J335J are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
