ECW-H8103HL Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECW-H8103HL is a 10000 pF film capacitor manufactured by Panasonic Electronic Components, rated for 800V DC operation with ±3% tolerance. This component features polypropylene (PP) metallized dielectric construction in a radial through-hole package, designed for high-frequency and switching applications. The ECW-H8103HL is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECW-H8103HL is determined by the following critical parameters:

• Capacitance Value: Must be 10000 pF (exact match required)
• Voltage Rating - DC: Must be 800V or higher
• Tolerance: Must be ±3% or tighter
• Dielectric Material: Must be Polypropylene (PP), Metallized
• Mounting Type: Must be Through Hole
• Package Type: Must be Radial
• Termination: Must be PC Pins

The ECW-H8103HA meets all substitution criteria as a direct equivalent. Both components share identical capacitance, tolerance, DC voltage rating, dielectric composition, mounting configuration, and termination type. Variations in physical dimensions and operating temperature range do not preclude substitution when circuit board layout and thermal environment accommodate the differences.

Parameter Comparison

Engineering Selection Recommendations

The ECW-H8103HA is a direct functional equivalent to the obsolete ECW-H8103HL. Both components are manufactured by Panasonic Electronic Components within the ECW-H series and share identical electrical specifications for capacitance, tolerance, and DC voltage rating.

The ECW-H8103HA offers the advantage of active product status, ensuring continued availability and supply chain reliability. The substitute part is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Physical dimension differences between the two parts must be evaluated against circuit board layout constraints. The ECW-H8103HA is smaller in length, width, and height, with reduced lead spacing (12.50mm versus 15.00mm). These dimensional reductions may facilitate board redesign or accommodate space-constrained applications.

The operating temperature range of the ECW-H8103HA extends to 105°C maximum, compared to 110°C for the ECW-H8103HL. This 5°C difference is negligible for most applications but should be confirmed against system thermal specifications.

Frequently Asked Questions (FAQ)

Q: Can the ECW-H8103HA directly replace the ECW-H8103HL without circuit modification?

A: Electrical substitution is direct. The capacitance, tolerance, and DC voltage rating are identical. Physical board layout must accommodate the smaller dimensions and reduced lead spacing of the ECW-H8103HA. PCB footprint adjustment may be required.

Q: What is the significance of the AC voltage rating difference?

A: The ECW-H8103HL does not specify an AC voltage rating. The ECW-H8103HA specifies 283V AC. If the application requires AC voltage operation, the ECW-H8103HA rating must be evaluated against circuit requirements. For DC-only applications, this parameter is not relevant to substitution.

Q: Are there compliance differences between the two parts?

A: The ECW-H8103HA is ROHS3 compliant and REACH unaffected. The ECW-H8103HL compliance status is not specified. For applications requiring environmental compliance certification, the ECW-H8103HA meets current regulatory standards.

Q: Does the smaller size of the ECW-H8103HA affect performance?

A: Electrical performance is determined by capacitance, tolerance, voltage rating, and dielectric material—all identical between the two parts. Physical size reduction does not alter electrical characteristics. Board layout compatibility must be independently verified.

Q: What is the lead spacing difference, and why does it matter?

A: The ECW-H8103HL has 15.00mm lead spacing; the ECW-H8103HA has 12.50mm lead spacing. This affects PCB footprint compatibility. Existing through-hole patterns designed for 15.00mm spacing require modification to accommodate 12.50mm spacing.

Q: Is the ECW-H8103HA available in the same packaging as the ECW-H8103HL?

A: Both parts use radial through-hole packaging with PC pin termination. The ECW-H8103HA is supplied in bulk packaging, while the ECW-H8103HL packaging type is not specified. Packaging format does not affect component functionality or substitution eligibility.
