ECW-H8333HL Equivalent & Substitute Parts

Part Overview

The ECW-H8333HL is a 0.033 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 part is currently listed as obsolete, making identification of suitable substitute components necessary for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-H8333HL is determined by the following critical parameters:

• Capacitance value: 0.033 µF (exact match required)
• DC voltage rating: 800V minimum
• Dielectric material: Polypropylene (PP), Metallized
• Tolerance: ±3%
• Mounting type: Through Hole, Radial configuration
• Termination style: PC Pins

The ECW-H8333HA qualifies as a substitute based on matching all core electrical specifications (capacitance, voltage rating, dielectric type, and tolerance) and maintaining compatible physical mounting characteristics (radial through-hole with PC pin termination). Both parts belong to the ECW-H base product family and share identical electrical performance parameters for the specified application requirements.

Parameter Comparison

Engineering Selection Recommendations

The ECW-H8333HA is an active product substitute for the obsolete ECW-H8333HL. Both components share identical electrical specifications for capacitance (0.033 µF), DC voltage rating (800V), tolerance (±3%), and dielectric composition (polypropylene metallized).

Physical dimensions and lead spacing differ between the two parts. The ECW-H8333HA features a more compact footprint (15.70mm x 8.40mm versus 23.00mm x 5.50mm) with reduced lead spacing (12.50mm versus 20.00mm). PCB layout verification is required to confirm mechanical compatibility with existing through-hole mounting patterns.

The ECW-H8333HA operates across -40°C to 105°C, compared to the original part's -40°C to 110°C range. This 5°C difference at the upper temperature limit should be evaluated against specific application thermal requirements.

The ECW-H8333HA carries RoHS3 compliance and REACH unaffected status, providing regulatory alignment for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the ECW-H8333HA directly replace the ECW-H8333HL without circuit modification?

A: Electrical substitution is valid based on matching capacitance, voltage rating, tolerance, and dielectric type. Physical mounting compatibility requires PCB layout verification due to differences in component dimensions and lead spacing.

Q: What are the key differences between these two parts?

A: The primary differences are physical dimensions, lead spacing, and product status. The ECW-H8333HA is more compact with 12.50mm lead spacing versus 20.00mm on the ECW-H8333HL. The ECW-H8333HA is currently active in production, while the ECW-H8333HL is obsolete.

Q: Does the 5°C difference in maximum operating temperature affect substitution suitability?

A: The ECW-H8333HA operates to 105°C maximum versus 110°C for the original part. Substitution is appropriate for applications where the operating temperature does not exceed 105°C. Applications requiring operation above 105°C require alternative component selection.

Q: Are there packaging differences between these parts?

A: The ECW-H8333HL is supplied in standard packaging, while the ECW-H8333HA is supplied in bulk packaging. Both use radial through-hole configuration with PC pin termination.

Q: What compliance certifications apply to the substitute part?

A: The ECW-H8333HA is RoHS3 compliant and REACH unaffected. Both parts carry EAR99 export classification and HTSUS code 8532.25.0030.
