ECW-FD2J155JC Equivalent & Substitute Parts

Part Overview

The ECW-FD2J155JC is a 1.5 µF film capacitor rated for 630V DC, manufactured by Panasonic Electronic Components. This radial through-hole component uses polypropylene (PP) metallized dielectric technology and is designed for EMI/RFI suppression, high-frequency switching, and high pulse applications. The part is currently active in production with 789 units in stock and maintains ROHS3 compliance and REACH unaffected status. Substitute parts are identified when equivalent electrical and mechanical parameters are available from the same manufacturer series, enabling component sourcing flexibility while maintaining circuit performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECW-FD2J155JC are identified based on strict equivalence of the following critical parameters:

• Capacitance value: 1.5 µF
• DC voltage rating: 630V
• Tolerance: ±5%
• Dielectric material: Polypropylene (PP), Metallized
• Operating temperature range: -40°C ~ 105°C
• Mounting type: Through Hole
• Package type: Radial
• Physical dimensions and lead spacing
• Termination style: PC Pins
• Manufacturer series: ECW-F(D)

The ECW-FD2J155J qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications, physical dimensions, and mechanical compatibility. The presence of an AC voltage rating (141V) in the substitute part does not alter DC circuit compatibility, as the DC rating remains the primary specification for this application category.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FD2J155JC and ECW-FD2J155J are active production parts from Panasonic Electronic Components within the ECW-F(D) series. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical differences.

The ECW-FD2J155J offers higher inventory availability (1992 units versus 789 units), making it suitable for applications where supply continuity is a priority. Both parts maintain identical ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in all markets.

For applications requiring the ECW-FD2J155JC specifically, the ECW-FD2J155J provides direct functional substitution without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2J155J be used as a direct replacement for ECW-FD2J155JC?

A: Yes. Both parts share identical DC voltage rating (630V), capacitance (1.5 µF), tolerance (±5%), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), and physical dimensions (0.996" L x 0.406" W with 0.886" lead spacing). No circuit modifications or board layout changes are required.

Q: What is the significance of the AC voltage rating on the substitute part?

A: The ECW-FD2J155J includes an AC voltage rating of 141V, while the ECW-FD2J155JC does not specify an AC rating. For DC applications, the DC voltage rating (630V for both parts) is the controlling specification. The AC rating does not affect DC circuit performance or compatibility.

Q: Are both parts suitable for the same applications?

A: Yes. Both parts are rated for EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT applications. Identical electrical and mechanical specifications ensure equivalent performance in these application categories.

Q: What are the compliance differences between these parts?

A: There are no compliance differences. Both parts are ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements for component selection.

Q: Which part should be selected based on availability?

A: The ECW-FD2J155J has higher current inventory (1992 units) compared to the ECW-FD2J155JC (789 units). For applications where supply continuity is critical, the substitute part offers better availability without sacrificing electrical or mechanical performance.
