Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Ohmite 25JR20 are qualified based on strict electrical and mechanical parameter matching:

• Resistance value: 200 mOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 5W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial (exact match required)
• Physical dimensions: 0.276" Dia x 1.016" L / 7.00mm x 25.80mm (exact match required)
• Features: Flame retardant coating and safety construction (exact match required)
• Terminations: 2-pin axial configuration (exact match required)

The Ohmite 25JR20E qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 25JR20 and 25JR20E are Active product status components manufactured by Ohmite with identical electrical and mechanical specifications. The primary distinction is regulatory compliance: the 25JR20E is ROHS3 compliant, while the 25JR20 is RoHS non-compliant. Both parts maintain REACH Unaffected status and share the same ECCN and HTSUS classifications.

Selection between these parts depends on application regulatory requirements. For applications requiring RoHS3 compliance, the 25JR20E is the appropriate choice. For applications without RoHS compliance mandates, either part is electrically and mechanically interchangeable. Packaging differs between bulk (25JR20E) and standard (25JR20) configurations.

Frequently Asked Questions (FAQ)

Q: Can the 25JR20E replace the 25JR20 in existing designs?

A: Yes. The 25JR20E is electrically and mechanically identical to the 25JR20. Both components share the same resistance value (200 mOhms), tolerance (±5%), power rating (5W), wirewound composition, axial package, and physical dimensions (0.276" Dia x 1.016" L). Direct substitution is valid from an electrical and mechanical standpoint.

Q: What is the difference between the 25JR20 and 25JR20E?

A: The primary difference is RoHS compliance status. The 25JR20E is ROHS3 compliant, while the 25JR20 is RoHS non-compliant. Both parts are otherwise identical in electrical performance, mechanical construction, and physical dimensions. Packaging format also differs: 25JR20E is supplied in bulk packaging.

Q: Are there any thermal or environmental performance differences between these parts?

A: No. Both parts are manufactured by Ohmite in the same Series 20 line with identical flame retardant coating and safety features. No temperature coefficient or operating temperature data is provided for either part, indicating equivalent thermal performance characteristics.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, specify the 25JR20E. For applications without RoHS compliance mandates, either part is suitable. Verify packaging requirements: the 25JR20E is supplied in bulk format.

Q: Are these parts pin-compatible?

A: Yes. Both parts feature identical 2-pin axial termination configuration and matching physical dimensions (0.276" Dia x 1.016" L / 7.00mm x 25.80mm), ensuring direct mechanical and electrical compatibility in PCB layouts and through-hole applications.
