ECW-FD2W155KC Equivalent & Substitute Parts

Part Overview

The ECW-FD2W155KC is a 1.5 µF film capacitor manufactured by Panasonic Electronic Components, rated for 450V DC operation with polypropylene (PP) metallized dielectric construction. This radial through-hole component is designed for EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT applications. The part maintains Active product status with ROHS3 compliance and REACH unaffected certification. Substitute parts are identified when electrical specifications, mechanical dimensions, and termination characteristics remain within the allowed parameters for direct circuit board replacement.

Substitute Part Grouping Explanation

Substitute parts for the ECW-FD2W155KC are identified based on strict equivalence across the following critical parameters:

• Capacitance Value: 1.5 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 450V (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -40°C ~ 110°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Physical Dimensions: 0.689" L x 0.366" W, 0.492" Height, 0.591" Lead Spacing (exact match required)
• Termination: PC Pins (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

Substitution is valid only when all parameters remain identical. Variations in manufacturer part number suffix do not affect functional equivalence when all electrical and mechanical specifications are preserved.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2W155K be used as a direct replacement for ECW-FD2W155KC?

A: Yes. Both parts are parametrically equivalent across all electrical specifications (1.5 µF, ±10% tolerance, 450V DC), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 110°C), and mechanical dimensions (0.689" L x 0.366" W, 0.492" height, 0.591" lead spacing). Both are radial through-hole components with PC pin termination and identical compliance status.

Q: Are there physical dimension differences between these parts?

A: No. Both ECW-FD2W155KC and ECW-FD2W155K share identical physical dimensions: 0.689" length x 0.366" width, 0.492" seated height maximum, and 0.591" lead spacing. Both are packaged as radial through-hole components suitable for standard PCB mounting.

Q: What is the difference between ECW-FD2W155KC and ECW-FD2W155K part numbers?

A: The part numbers differ only in the suffix designation (C versus K). All electrical parameters, mechanical specifications, dielectric material, voltage rating, capacitance value, tolerance, and compliance certifications remain identical between these variants.

Q: Are both parts suitable for EMI/RFI suppression applications?

A: Yes. Both ECW-FD2W155KC and ECW-FD2W155K are specified for EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT applications. The polypropylene metallized dielectric construction and 450V DC rating support these application requirements.

Q: Do these parts require any special handling or storage considerations?

A: Moisture Sensitivity Level (MSL) is Not Applicable for both parts, indicating standard handling and storage procedures are sufficient.
