Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FE2J154KA is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.15 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 configuration: Radial (exact match required)
• Lead spacing: 0.591" / 15.00mm (exact match required)
• Termination style: PC Pins (exact match required)

The ECW-FE2J154K qualifies as a parametric equivalent based on full alignment with all critical electrical and mechanical specifications. Both parts share the same base product number (ECW-FE) and series designation (ECWFE), confirming design compatibility within the Panasonic ECWFE film capacitor family.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FE2J154KA and ECW-FE2J154K are active production components with full ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future manufacturing requirements. Selection between these parts should be based on inventory availability and supply chain logistics, as electrical and mechanical specifications are identical. The ECW-FE2J154K currently maintains higher inventory levels (2345 pcs vs. 1031 pcs), which may provide supply chain advantages for high-volume applications. Both parts are suitable for direct substitution in EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT circuit applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can ECW-FE2J154K be used as a direct replacement for ECW-FE2J154KA?

A: Yes. Both parts share identical electrical specifications (0.15 µF, ±10%, 630V DC), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), and mechanical configuration (radial through-hole, 15.00mm lead spacing, PC pin termination). No circuit redesign or PCB layout modification is required.

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

A: The ECW-FE2J154KA does not specify an AC voltage rating. The ECW-FE2J154K specifies 141V AC. For applications requiring AC voltage operation, the ECW-FE2J154K provides explicit AC rating documentation. For DC-only applications, both parts are equivalent.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts have identical dimensions: 0.689" L x 0.236" W (17.50mm x 6.00mm), maximum seated height of 0.453" (11.50mm), and lead spacing of 0.591" (15.00mm). PCB footprints and mounting requirements are identical.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both ECW-FE2J154KA and ECW-FE2J154K are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance restrictions for electronic components.

Q: What applications are these capacitors designed for?

A: Both parts are specified for EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT applications. The polypropylene metallized dielectric provides low ESR and stable performance across the -40°C ~ 105°C operating range.
