Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FD2J185JC is determined by strict equivalence across the following critical parameters:

• Capacitance value: 1.8 µF (exact match required)
• Tolerance: ±5% (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 type: PC Pins (exact match required)

The ECW-FD2J185J qualifies as a parametric equivalent based on matching all critical electrical and mechanical specifications. The presence of an AC voltage rating (141V) in the substitute part does not affect DC circuit compatibility and represents an additional specification parameter.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FD2J185JC and ECW-FD2J185J are active production parts manufactured by Panasonic Electronic Components. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The ECW-FD2J185J offers higher inventory availability at 1432 units compared to 746 units for the main part number. Selection between these parts should be based on availability requirements and supply chain considerations, as electrical and mechanical specifications are identical for DC circuit applications.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2J185J be used as a direct replacement for ECW-FD2J185JC?

A: Yes. The ECW-FD2J185J is a parametric equivalent with identical capacitance (1.8 µF), tolerance (±5%), DC voltage rating (630V), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), physical dimensions, lead spacing, and termination type. Both parts are through-hole radial capacitors with PC pin termination.

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

A: The ECW-FD2J185J includes an AC voltage rating specification of 141V, which the main part does not specify. This additional parameter does not affect compatibility in DC applications and represents supplementary electrical characterization of the substitute part.

Q: Are there any physical compatibility concerns when substituting these parts?

A: No. Both parts share identical physical dimensions (0.996" L x 0.441" W / 25.30mm x 11.20mm), maximum seated height (0.709" / 18.00mm), and lead spacing (0.886" / 22.50mm). PCB footprints and mounting requirements are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ECW-FD2J185JC and ECW-FD2J185J are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8532.25.0070.

Q: Which part should be selected based on availability?

A: The ECW-FD2J185J has higher inventory availability at 1432 units in stock compared to 746 units for the ECW-FD2J185JC. Selection should prioritize supply chain requirements and lead time considerations.
