ECW-H8393HV Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECW-H8393HV is a 0.039 µF film capacitor manufactured by Panasonic Electronic Components, rated for 800V DC operation with ±3% tolerance. This radial through-hole component utilizes polypropylene (PP) metallized dielectric technology and is designed for high-frequency and switching applications. The part maintains Active product status with full ROHS3 compliance and REACH unaffected certification. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained within the allowed specifications for this product category.

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-H8393HV is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.039 µF (exact match required)
• Tolerance: ±3% (exact match required)
• DC voltage rating: 800V (exact match required)
• 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 configuration: Radial (exact match required)
• Physical dimensions and lead spacing (exact match required)
• Termination type: PC Pins (exact match required)

The ECW-H8393HA qualifies as a parametric equivalent based on these criteria. Both parts share identical capacitance, tolerance, DC voltage rating, dielectric composition, temperature range, mounting configuration, and physical footprint. The AC voltage rating specification (283V) is provided for the ECW-H8393HA and represents an additional operational parameter that does not affect DC-rated substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-H8393HV and ECW-H8393HA maintain Active product status with identical regulatory compliance certifications. Both parts are ROHS3 compliant and REACH unaffected, ensuring compatibility with current environmental and regulatory requirements. The ECW-H8393HA is available with higher inventory levels (1779 Pcs vs. 1112 Pcs), which may influence procurement decisions based on supply chain requirements. Selection between these parts should be based on application-specific AC voltage requirements, as the ECW-H8393HA specifies an AC rating of 283V while the ECW-H8393HV does not include an AC specification.

Frequently Asked Questions (FAQ)

Q: Can the ECW-H8393HA replace the ECW-H8393HV in all applications?

A: The ECW-H8393HA is electrically and mechanically equivalent to the ECW-H8393HV across all specified DC parameters. Both parts share identical capacitance (0.039 µF), tolerance (±3%), DC voltage rating (800V), dielectric material, operating temperature range, and physical footprint. The ECW-H8393HA includes an AC voltage specification (283V) not provided for the ECW-H8393HV. Substitution is valid for applications where the DC parameters are the primary design criteria.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the ECW-H8393HV and ECW-H8393HA share identical physical dimensions (0.618" L x 0.350" W / 15.70mm x 8.90mm), maximum seated height (0.583" / 14.80mm), and lead spacing (0.492" / 12.50mm). Both are radial through-hole components with PC pin termination, ensuring identical PCB footprint compatibility.

Q: What is the difference between the ECW-H(V) and ECW-H(A) series designations?

A: The series designation suffix indicates variant classification within the ECW-H base product family. Both variants maintain identical electrical and mechanical specifications for the 0.039 µF, 800V DC rated capacitor. The series designation does not affect substitution eligibility when all other parameters are equivalent.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the ECW-H8393HV and ECW-H8393HA are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What applications are these capacitors designed for?

A: Both parts are specified for high-frequency and switching applications. The polypropylene metallized dielectric composition and 800V DC rating support these operational requirements.
