Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 40J82R is determined by the following critical parameters:

• Resistance Value: 82 Ohms (exact match required)
• Tolerance: ±5% (defines acceptable resistance range)
• Power Rating: 10W (minimum thermal dissipation capability)
• Package Configuration: Axial (mechanical fit and lead compatibility)
• Composition: Wirewound (electrical performance characteristics)

The substitute part 40J82RE meets all these criteria, providing functional equivalence for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 40J82R and 40J82RE are active Ohmite products classified under identical ECCN (EAR99) and HTSUS codes, indicating equivalent regulatory treatment. Both components share RoHS non-compliant status. The 40J82RE is available in bulk packaging, whereas the 40J82R specification does not specify packaging format. Selection between these parts should be based on packaging requirements, inventory availability, and supply chain considerations rather than electrical or mechanical differences.

Frequently Asked Questions (FAQ)

Q: Can the 40J82RE directly replace the 40J82R in existing designs?

A: Yes. Both components are 82 ohm, ±5% tolerance, 10W axial wirewound resistors from Ohmite with identical electrical specifications and package configuration. Direct substitution is supported for applications where the specified parameters are the design requirement.

Q: Are there differences in temperature performance between these parts?

A: The 40J82R specifies a temperature coefficient of ±20ppm/°C. The 40J82RE temperature coefficient is not provided in available documentation. For applications with strict temperature stability requirements, the 40J82R specification should be verified.

Q: What is the significance of the packaging difference?

A: The 40J82R packaging format is not specified in the provided data. The 40J82RE is supplied in bulk packaging. Packaging selection depends on assembly requirements, handling procedures, and inventory management practices.

Q: Are both parts suitable for RoHS-compliant applications?

A: No. Both the 40J82R and 40J82RE are marked as RoHS non-compliant. Applications requiring RoHS compliance cannot use either component without design modification or alternative part selection.

Q: What is the physical footprint compatibility?

A: Both components share identical axial package dimensions: 0.406" diameter × 1.902" length (10.30mm × 48.30mm). PCB layout and mechanical clearance requirements are equivalent.
