ECW-H8473HV Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECW-H8473HV is a 0.047 µF film capacitor manufactured by Panasonic Electronic Components, rated for 800V DC operation with ±3% tolerance. This polypropylene metallized radial capacitor is designed for high-frequency and switching applications, featuring through-hole mounting with PC pin termination. The part is currently active in production with ROHS3 compliance and is suitable for demanding electronic circuits requiring stable capacitance performance across the -40°C to 105°C operating temperature range.

Equivalent and substitute parts are identified to provide design flexibility, support supply chain continuity, and accommodate specific application requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-H8473HV is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.047 µF (exact match required)
• Tolerance: ±3% (exact match required)
• DC voltage rating: 800V (minimum requirement; higher ratings acceptable)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Physical dimensions: 0.618" L x 0.382" W, 0.614" height, 0.492" lead spacing (exact match required)
• Termination: PC Pins (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

The ECW-H8473HA meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-H8473HV and ECW-H8473HA are active production parts manufactured by Panasonic Electronic Components with ROHS3 compliance certification. Selection between these parts should be based on application-specific AC voltage requirements and supply chain availability.

The ECW-H8473HV is suitable for applications where AC voltage specification is not a design constraint. The ECW-H8473HA provides an additional AC voltage rating of 283V, offering expanded operational flexibility for circuits requiring AC voltage specification.

Both parts maintain identical DC voltage rating (800V), capacitance value (0.047 µF), tolerance (±3%), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), and physical dimensions. Interchangeability is confirmed for through-hole PCB mounting applications with standard 12.50mm lead spacing.

Frequently Asked Questions (FAQ)

Q: Can ECW-H8473HA be used as a direct replacement for ECW-H8473HV?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 0.047 µF capacitance, ±3% tolerance, 800V DC rating, polypropylene metallized dielectric, -40°C to 105°C operating temperature, and identical physical dimensions with 12.50mm lead spacing. The ECW-H8473HA includes an additional AC voltage rating specification (283V) not present in the ECW-H8473HV.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by exact equivalence in capacitance (0.047 µF), tolerance (±3%), DC voltage rating (800V minimum), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), mounting type (through hole), package style (radial), physical dimensions (0.618" L x 0.382" W, 0.614" height, 0.492" lead spacing), termination type (PC pins), and compliance certification (ROHS3).

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

A: No. Both the ECW-H8473HV and ECW-H8473HA share identical physical dimensions: 0.618" length x 0.382" width (15.70mm x 9.70mm), maximum seated height of 0.614" (15.60mm), and lead spacing of 0.492" (12.50mm). PCB layout and mounting hole spacing remain unchanged.

Q: What is the significance of the AC voltage rating on the ECW-H8473HA?

A: The ECW-H8473HA specifies an AC voltage rating of 283V, providing additional design information for applications requiring AC voltage operation. The ECW-H8473HV does not include an AC voltage specification. Both parts maintain the same 800V DC rating and are suitable for high-frequency and switching applications.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the ECW-H8473HV and ECW-H8473HA are ROHS3 compliant and meet environmental regulatory requirements for electronic component manufacturing and use.
