ECW-H8123HV Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECW-H8123HV is a 0.012 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 is currently active in production with 895 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 within the allowed parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-H8123HV is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must be 0.012 µF (no tolerance variation permitted)
• Tolerance: Must be ±3%
• DC Voltage Rating: Must be 800V or higher
• Dielectric Material: Must be Polypropylene (PP), Metallized
• Operating Temperature Range: Must support -40°C ~ 105°C
• Mounting Type: Must be Through Hole
• Package / Case: Must be Radial
• Lead Spacing: Must be 0.492" (12.50mm)
• Termination: Must be PC Pins

The ECW-H8123HA meets all substitution criteria and is classified as a parametric equivalent. Both parts share the same base product number (ECW-H) and differ only in series designation (V versus A variant) and AC voltage rating specification, which does not affect DC circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-H8123HV and ECW-H8123HA are active production components manufactured by Panasonic Electronic Components with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on inventory availability and supply chain requirements rather than electrical or mechanical performance differences.

The ECW-H8123HV is the primary specification with 895 units in stock. The ECW-H8123HA is a direct parametric equivalent with 1,089 units available, providing increased inventory flexibility. Both parts satisfy identical circuit requirements for 0.012 µF, 800V DC film capacitor applications in high-frequency and switching circuits.

Frequently Asked Questions (FAQ)

Q: Can ECW-H8123HA be used as a direct replacement for ECW-H8123HV in PCB assembly?

A: Yes. Both parts are mechanically and electrically equivalent. Lead spacing (0.492"), package dimensions (0.606" L x 0.228" W), and height (0.461" max) are identical. PCB footprints designed for either part are interchangeable.

Q: What is the difference between the V and A series designations?

A: The V and A designations indicate different product series within the ECW-H base product line. The ECW-H8123HA includes an AC voltage rating specification (283V), while the ECW-H8123HV does not specify AC rating. For DC-only applications, this difference is not relevant to circuit performance.

Q: Are both parts suitable for high-frequency and switching applications?

A: Yes. Both the ECW-H8123HV and ECW-H8123HA are specified for high-frequency and switching applications with identical operating temperature ranges (-40°C ~ 105°C) and dielectric material (polypropylene metallized).

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Electrical specifications (0.012 µF, ±3% tolerance, 800V DC), mechanical dimensions, lead spacing, and termination type are identical between both parts, allowing direct substitution in existing circuit designs without modification.
