ECW-H8183HL Equivalent & Substitute Parts

Part Overview

The ECW-H8183HL is a 0.018 µF film capacitor rated for 800V DC operation, manufactured by Panasonic Electronic Components. This radial polypropylene metallized capacitor is designed for high-frequency and switching applications with a ±3% tolerance and operating temperature range of -40°C to 110°C. The ECW-H8183HL carries an obsolete product status, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-H8183HL is determined by the following critical parameters:

• Capacitance Value: Must be 0.018 µF (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 / Case: Must be Radial
• Termination: Must be PC Pins

The ECW-H8183HA meets all substitution criteria. Both parts share identical capacitance, tolerance, dielectric material, mounting type, package style, and termination configuration. The ECW-H8183HA maintains the required 800V DC voltage rating and operates within compatible temperature parameters for most applications.

Parameter Comparison

Engineering Selection Recommendations

The ECW-H8183HA is a direct functional substitute for the obsolete ECW-H8183HL. Both capacitors are manufactured by Panasonic Electronic Components within the ECW-H series and share identical electrical specifications for capacitance, voltage rating, tolerance, and dielectric material.

The ECW-H8183HA carries Active product status with ROHS3 compliance and REACH Unaffected designation, providing regulatory continuity for new designs and ongoing production. The substitute part exhibits slightly reduced physical dimensions and lead spacing compared to the main part, which may require PCB layout verification for existing designs.

The operating temperature maximum of the ECW-H8183HA is 105°C versus 110°C for the ECW-H8183HL. This 5°C difference is acceptable for applications where the ECW-H8183HL operates below 105°C.

Frequently Asked Questions (FAQ)

Q: Can the ECW-H8183HA be used as a direct replacement for the ECW-H8183HL?

A: Yes. Both parts have identical capacitance (0.018 µF), tolerance (±3%), DC voltage rating (800V), dielectric material (Polypropylene metallized), mounting type (Through Hole), package style (Radial), and termination (PC Pins). Physical dimensions and lead spacing differ; PCB layout compatibility must be confirmed.

Q: What are the physical differences between these parts?

A: The ECW-H8183HA is smaller than the ECW-H8183HL. Length is 15.70mm versus 18.00mm, width is 6.60mm versus 5.50mm, height is 12.50mm versus 14.00mm, and lead spacing is 12.50mm versus 15.00mm. Verify PCB hole spacing and component clearance before substitution.

Q: Are there compliance differences between the main part and substitute?

A: The ECW-H8183HA is ROHS3 compliant and REACH Unaffected. The ECW-H8183HL compliance status is not specified. For applications requiring regulatory compliance documentation, the ECW-H8183HA provides explicit certification.

Q: What is the temperature operating range difference?

A: The ECW-H8183HL operates from -40°C to 110°C, while the ECW-H8183HA operates from -40°C to 105°C. The 5°C difference at the upper limit is acceptable for most applications operating below 105°C.

Q: Why is the ECW-H8183HL listed as obsolete?

A: The ECW-H8183HL has reached end-of-life status. The ECW-H8183HA remains in active production and is the recommended alternative for new designs and ongoing procurement.
