Substitute Part Grouping Explanation

Substitution for the ECW-FD2J155KC is determined by strict equivalence across the following critical parameters:

  • Capacitance Value: 1.5 µF (exact match required)
  • DC Voltage Rating: 630V (minimum requirement; higher ratings acceptable)
  • Tolerance: ±10% (matching tolerance band)
  • Dielectric Type: Polypropylene (PP), Metallized (same technology)
  • Mounting Configuration: Through Hole, Radial package
  • Physical Dimensions: 0.996" L x 0.406" W with 0.886" lead spacing (PCB layout compatibility)
  • Operating Temperature: -40°C ~ 105°C (functional range)
  • Termination Style: PC Pins (soldering compatibility)

The ECW-FD2J155K qualifies as a parametric equivalent based on identical electrical specifications, dielectric material, physical form factor, and thermal operating range. Both parts are manufactured by Panasonic Electronic Components within the ECW-F(D) series.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2J155K be used as a direct replacement for ECW-FD2J155KC?

A: Yes. Both parts share identical capacitance (1.5 µF), DC voltage rating (630V), tolerance (±10%), dielectric material (polypropylene metallized), physical dimensions, lead spacing, and operating temperature range. PCB layout and circuit performance remain unchanged.

Q: Are there any differences in electrical performance between these parts?

A: No. The electrical specifications for capacitance, voltage rating, and temperature operating range are identical. The ECW-FD2J155K includes an AC voltage rating (141V) not specified in the ECW-FD2J155KC datasheet, but this does not affect DC circuit operation.

Q: Do both parts fit the same PCB footprint?

A: Yes. Both parts have identical physical dimensions (0.996" L x 0.406" W) and lead spacing (0.886"), ensuring direct PCB compatibility without layout modifications.

Q: Are compliance certifications equivalent?

A: Yes. Both parts carry ROHS3 compliance and REACH unaffected status, meeting identical regulatory requirements for modern electronic assemblies.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection may be based on current inventory availability, supply chain lead times, or procurement preferences. Both maintain active production status.
