Substitute Part Grouping Explanation

Substitution of the TWM3J82R is determined by strict equivalence across the following critical parameters:

• Resistance value: 82 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Metal Oxide Film
• Package configuration: Radial lead
• Temperature coefficient: ±350ppm/°C
• Operating temperature range: -55°C to 275°C
• Safety and flame-proof characteristics

The TWM3J82RE qualifies as a direct substitute, maintaining identical electrical specifications and physical form factor while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TWM3J82RE is the appropriate substitute for the obsolete TWM3J82R. Both components maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the TWM3J82RE is active and carries RoHS compliance certification, whereas the TWM3J82R is obsolete and non-compliant. For new designs and ongoing production requiring compliance with current regulatory standards, the TWM3J82RE is the specified replacement. Physical dimensions and lead configuration are equivalent, ensuring direct board-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can TWM3J82RE be used as a direct replacement for TWM3J82R?

A: Yes. Both components share identical resistance value (82 Ohms), tolerance (±5%), power rating (3W), composition (metal oxide film), package type (radial), temperature coefficient (±350ppm/°C), and operating temperature range (-55°C to 275°C). Physical dimensions and lead configuration are equivalent.

Q: What is the primary reason to substitute TWM3J82R?

A: The TWM3J82R is classified as obsolete. The TWM3J82RE provides continuity of supply as an active product from the same manufacturer and series.

Q: Are there compliance differences between these parts?

A: Yes. The TWM3J82RE is RoHS compliant with MSL rating of 1 (Unlimited), while the TWM3J82R is RoHS non-compliant. For applications requiring regulatory compliance, the TWM3J82RE is required.

Q: Will PCB layout require modification for substitution?

A: No. Both components have identical radial package configuration and maximum seated height of 1.024" (26.00mm). No layout changes are necessary.

Q: Are the electrical performance characteristics identical?

A: Yes. Temperature coefficient, operating temperature range, and all specified electrical parameters are identical between both parts.
