ECW-H6274HC Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECW-H6274HC is a 0.27 µF film capacitor manufactured by Panasonic Electronic Components, designed for general-purpose applications requiring high voltage performance. This radial polypropylene (PP) metallized capacitor operates at 630V DC and maintains performance across a wide temperature range of -40°C to 105°C. The part is currently active in production with 1400 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-H6274HC is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.27 µF (exact match required)
• Tolerance: ±3% (exact match required)
• Voltage rating: 630V DC / 223V AC (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Operating temperature range: -40°C to 105°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.689" / 17.50mm (exact match required)
• Termination style: PC Pins (exact match required)

The ECW-H6274HCC meets all substitution criteria as a parametric equivalent within the ECW-H series from Panasonic Electronic Components.

Parameter Comparison

Engineering Selection Recommendations

Both ECW-H6274HC and ECW-H6274HCC are active production parts from Panasonic Electronic Components with identical electrical and mechanical specifications. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use. Selection between these parts may be based on inventory availability, supply chain logistics, or procurement lead times, as all functional and compliance parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can ECW-H6274HCC be used as a direct replacement for ECW-H6274HC?

A: Yes. The ECW-H6274HCC is a parametric equivalent with identical capacitance (0.27 µF), tolerance (±3%), voltage rating (630V DC / 223V AC), dielectric material (Polypropylene metallized), operating temperature range (-40°C to 105°C), physical dimensions, lead spacing, and termination style. Both parts are through-hole radial configurations with PC pin termination.

Q: Are there any differences in physical footprint between these parts?

A: No. Both parts share identical dimensions: 0.815" L x 0.551" W (20.70mm x 14.00mm) with a maximum seated height of 0.803" (20.40mm) and lead spacing of 0.689" (17.50mm). PCB layout and mounting hole spacing remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ECW-H6274HC and ECW-H6274HCC are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What determines substitution eligibility for this capacitor?

A: Substitution is based on exact equivalence across capacitance value, tolerance, DC and AC voltage ratings, dielectric material type, operating temperature range, mounting configuration, package style, lead spacing, and termination type. Any deviation in these parameters disqualifies a part as a direct substitute.

Q: Is there a performance difference between these parts?

A: No. Both parts are manufactured by Panasonic Electronic Components within the ECW-H series and meet identical electrical performance specifications across all rated parameters.
