Substitute Part Grouping Explanation

The TWM5J820E qualifies as a direct substitute based on matching electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Identical resistance value: 820 Ohms
• Identical tolerance: ±5%
• Identical power rating: 5W
• Identical composition: Metal Oxide Film
• Identical package configuration: Radial
• Identical operating temperature range: -55°C ~ 275°C
• Identical temperature coefficient: ±350ppm/°C
• Identical physical dimensions and height specifications
• Identical number of terminations: 2

The TWM5J820E maintains full electrical and mechanical compatibility with the obsolete TWM5J820, with the primary distinction being product status and RoHS compliance level.
