Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TWM5J8K2 is determined by strict equivalence across the following critical parameters:

• Resistance value: 8.2 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 5W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package configuration: Radial (exact match required)
• Operating temperature range: -55°C to 275°C (exact match required)
• Temperature coefficient: ±350ppm/°C (exact match required)
• Physical dimensions and termination count (exact match required)

The TWM5J8K2E qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The TWM5J8K2E is the direct equivalent substitute for the obsolete TWM5J8K2. Both components are manufactured by Ohmite and share identical electrical specifications, mechanical dimensions, and thermal characteristics.
