Frequently Asked Questions (FAQ)

Q: Can the ECW-FD2W185J be used as a direct replacement for the ECW-FD2W185JC?

A: Yes. The ECW-FD2W185J is a parametric equivalent that matches all critical electrical specifications (1.8 µF, ±5% tolerance, 450V DC), mechanical dimensions (0.689" L x 0.398" W, 15.00mm lead spacing), and compliance certifications (ROHS3, REACH unaffected) required for direct substitution.

Q: What is the difference between the ECW-FD2W185JC and ECW-FD2W185J?

A: The primary difference is the AC voltage rating specification. The ECW-FD2W185JC does not specify an AC voltage rating, while the ECW-FD2W185J specifies 84V AC. Both parts are identical in DC voltage rating (450V), capacitance (1.8 µF), dielectric material, physical dimensions, and all other electrical and mechanical parameters.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions: 0.689" length x 0.398" width (17.50mm x 10.10mm), maximum seated height of 0.524" (13.30mm), and lead spacing of 0.591" (15.00mm). Both use radial through-hole mounting with PC pin termination.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the ECW-FD2W185JC and ECW-FD2W185J are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component procurement and use.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. The identical mechanical specifications, lead spacing, and mounting type ensure that both parts are mechanically and electrically interchangeable in through-hole PCB designs without requiring layout modifications.

Q: What applications are these capacitors suitable for?

A: Both parts are specified for EMI/RFI suppression, high-frequency switching applications, and high pulse/DV/DT environments. The 450V DC rating and polypropylene dielectric material support these application requirements.
