Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-F6334JLC is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must be 0.33 µF
• Tolerance: Must be ±5%
• DC Voltage Rating: Must be 630V
• Dielectric Type: Must be Polypropylene (PP), Metallized
• Operating Temperature Range: Must be -40°C ~ 105°C
• Mounting Configuration: Must be Through Hole, Radial
• Lead Spacing: Must be 0.689" (17.50mm)
• Product Status: Must be Active

The ECW-F6334JL qualifies as a parametric equivalent based on full alignment with these criteria. Both parts share identical capacitance, tolerance, DC voltage rating, dielectric material, temperature range, mounting type, package configuration, and lead spacing specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-F6334JLC and ECW-F6334JL maintain Active product status with identical regulatory compliance certifications. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance restrictions. Selection between these parts is based on availability and inventory levels, as electrical and mechanical specifications are fully equivalent. The ECW-F6334JL currently maintains higher inventory availability at 1793 pieces compared to 766 pieces for the ECW-F6334JLC.

Frequently Asked Questions (FAQ)

Q: Can ECW-F6334JL be used as a direct replacement for ECW-F6334JLC?

A: Yes. Both parts share identical electrical specifications (0.33 µF, ±5% tolerance, 630V DC rating), dielectric material (polypropylene metallized), operating temperature range (-40°C to 105°C), and mechanical configuration (radial through-hole, 0.689" lead spacing). They are functionally interchangeable in circuit applications.

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

A: The ECW-F6334JLC does not specify an AC voltage rating. The ECW-F6334JL specifies 223V AC. This difference does not affect DC-only applications but should be considered if AC operation is required.

Q: Do both parts fit the same PCB footprint?

A: Yes. Both parts have identical physical dimensions (0.807" L x 0.449" W, 20.50mm x 11.40mm), maximum seated height (0.756", 19.20mm), and lead spacing (0.689", 17.50mm). PCB layout compatibility is maintained.

Q: What is the difference between ECW-F6334JLC and ECW-F6334JL part numbers?

A: Both parts belong to the ECW-F(L) series from Panasonic. The designation difference reflects internal product line variations, but electrical and mechanical specifications remain equivalent for substitution purposes.

Q: Are both parts currently available?

A: Yes. ECW-F6334JLC has 766 pieces in stock, and ECW-F6334JL has 1793 pieces in stock, both listed as new original inventory.
