Substitute Part Grouping Explanation

Substitution for the ECW-FD2J105KC is determined by strict equivalence across the following critical parameters:

• Capacitance value: 1 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 630V (exact match or higher required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match or wider range acceptable)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Physical dimensions and lead spacing (exact match required for PCB compatibility)
• Termination: PC Pins (exact match required)

The ECW-FD2J105K qualifies as a parametric equivalent based on these criteria. Both parts share identical capacitance, tolerance, voltage rating, dielectric composition, temperature range, mounting configuration, and physical footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FD2J105KC and ECW-FD2J105K are Active status products manufactured by Panasonic Electronic Components. Both parts maintain ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and inventory levels. The ECW-FD2J105K carries higher inventory availability (1411 Pcs) compared to the ECW-FD2J105KC (670 Pcs). From an engineering standpoint, either part satisfies the electrical and mechanical requirements for applications requiring 1 µF, 630V DC film capacitors with polypropylene dielectric in radial through-hole configuration.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2J105K be used as a direct replacement for ECW-FD2J105KC?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: capacitance (1 µF), tolerance (±10%), DC voltage rating (630V), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), mounting type (through hole), package configuration (radial), physical dimensions (25.30mm x 8.40mm), and lead spacing (22.50mm). PCB layout and circuit performance remain unchanged.

Q: What is the difference between these two part numbers?

A: The ECW-FD2J105K includes an AC voltage rating specification (141V) not listed for the ECW-FD2J105KC. All other electrical and mechanical parameters are identical. Both parts belong to the same ECW-F(D) series and share the same base product number ECW-FD.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical compliance status: ROHS3 compliant, REACH unaffected, and EAR99 ECCN classification. Both are suitable for applications with equivalent regulatory requirements.

Q: Does the radial through-hole package remain the same?

A: Yes. Both parts use identical radial through-hole configuration with PC pin termination, 22.50mm lead spacing, and 25.30mm x 8.40mm physical dimensions. No PCB redesign is required for substitution.

Q: Which part should be selected based on availability?

A: The ECW-FD2J105K has higher current inventory (1411 Pcs) versus the ECW-FD2J105KC (670 Pcs). For procurement purposes, the ECW-FD2J105K offers better availability while maintaining full electrical and mechanical equivalence.
