Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FE2J155KA is determined by strict equivalence across the following critical parameters:

• Capacitance value: 1.5 µF (exact match required)
• Tolerance: ±10% (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 style: PC Pins (exact match required)

The ECW-FE2J155K meets all substitution criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, physical form factors, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FE2J155KA and ECW-FE2J155K are active production parts manufactured by Panasonic Electronic Components and carry identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and procurement lead times. The ECW-FE2J155K currently has higher stock levels (1211 units versus 729 units), which may support faster fulfillment for high-volume applications. Both parts meet all regulatory and compliance requirements for deployment in EMI/RFI suppression, high-frequency switching, and high-pulse applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ECW-FE2J155K be used as a direct replacement for ECW-FE2J155KA?

A: Yes. Both parts are parametric equivalents with identical capacitance (1.5 µF), tolerance (±10%), DC voltage rating (630V), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), physical dimensions (26.00mm x 12.00mm), lead spacing (22.50mm), and termination style (PC Pins radial). They are functionally interchangeable in circuit applications.

Q: Are there any differences in AC voltage rating between these parts?

A: The ECW-FE2J155KA does not specify an AC voltage rating, while the ECW-FE2J155K specifies 141V AC. For DC-only applications, this difference is not relevant. For AC or mixed AC/DC applications, the ECW-FE2J155K AC rating should be verified against circuit requirements.

Q: Do both parts have the same physical footprint?

A: Yes. Both parts share identical dimensions (26.00mm length x 12.00mm width), maximum seated height (19.00mm), and lead spacing (22.50mm). They are mechanically interchangeable on PCBs designed for radial through-hole mounting.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry ECCN classification EAR99 and HTSUS code 8532.25.0070.

Q: Which part should be selected for new designs?

A: Both parts are active in production. Selection should be based on inventory availability, procurement lead times, and supply chain strategy. The ECW-FE2J155K currently has higher stock availability.
