Substitute Part Grouping Explanation

Substitution eligibility for the TWM3J2K0 is determined by strict equivalence across the following parameters:

  • Resistance value: 2 kOhms
  • Tolerance: ±5%
  • Power rating: 3W
  • Composition: Metal Oxide Film
  • Package configuration: Radial with 2 terminations
  • Operating temperature range: -55°C to 275°C minimum
  • Temperature coefficient: ±350ppm/°C
  • Physical dimensions: 0.492" L x 0.354" W, 1.024" seated height

The TWM3J2K0E meets all these criteria and is classified as a direct substitute. The primary distinction between the main part and its substitute relates to product status and compliance certifications rather than electrical or mechanical performance.
