Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FD2W155JC is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 1.5 µF
• DC voltage rating: 450V minimum
• Tolerance: ±5%
• Dielectric material: Polypropylene (PP), Metallized

Mechanical Parameters:

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.591" (15.00mm)
• Height seated maximum: 0.492" (12.50mm)
• Termination style: PC Pins

Compliance Parameters:

• RoHS3 Compliant status
• REACH Unaffected classification
• Active product status

The ECW-FD2W155J qualifies as a parametric equivalent based on matching all electrical specifications, mechanical dimensions, and compliance certifications. The presence of an AC voltage rating in the substitute part does not disqualify substitution, as the DC rating remains the controlling specification for this application category.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FD2W155JC and ECW-FD2W155J maintain Active product status with full regulatory compliance. Selection between these parts is based on inventory availability and supply chain considerations rather than electrical or mechanical differentiation.

The ECW-FD2W155JC carries 869 pieces in current stock inventory. The ECW-FD2W155J substitute carries 982 pieces in current stock inventory. Both parts satisfy RoHS3 compliance requirements and REACH unaffected classification, making either suitable for applications requiring regulatory adherence in consumer and industrial electronics.

For applications where component sourcing is constrained by lead time or allocation, the substitute part ECW-FD2W155J provides equivalent functional performance with identical electrical ratings, mechanical dimensions, and operating characteristics. No design modification or circuit re-evaluation is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2W155J be used as a direct replacement for ECW-FD2W155JC?

A: Yes. Both parts share identical capacitance (1.5 µF), DC voltage rating (450V), tolerance (±5%), dielectric material (polypropylene metallized), operating temperature range (-40°C to 110°C), and mechanical dimensions including lead spacing (15.00mm) and height (12.50mm). All compliance certifications match.

Q: What is the difference between these two part numbers?

A: The ECW-FD2W155J includes an AC voltage rating specification (84V) that is not present in the ECW-FD2W155JC datasheet. The DC voltage rating of 450V remains identical. This difference does not affect substitution eligibility for DC-biased applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.689" L x 0.366" W (17.50mm x 9.30mm) with a maximum seated height of 0.492" (12.50mm) and lead spacing of 0.591" (15.00mm). PCB layout and mechanical clearance requirements are identical.

Q: Do both parts meet RoHS3 compliance?

A: Yes. Both ECW-FD2W155JC and ECW-FD2W155J carry ROHS3 Compliant status and REACH Unaffected classification.

Q: Which part should be selected based on availability?

A: Selection should be based on current inventory levels and supply chain requirements. The ECW-FD2W155J currently carries higher stock availability (982 pieces versus 869 pieces). Both parts are Active status products from Panasonic Electronic Components.

Q: Are there any application restrictions when using the substitute part?

A: No. Both parts are rated for identical applications including EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT environments. Operating temperature range and voltage ratings are equivalent.
