Substitute Part Grouping Explanation

Substitution of the TWM5J470 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must match:

• Resistance value: 470 Ohms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Metal Oxide Film
• Package configuration: Radial with 2 terminations
• Operating temperature range: -55°C to 275°C
• Temperature coefficient: ±350ppm/°C
• Physical dimensions: 0.492" L x 0.354" W, height 1.024" maximum

The TWM5J470E meets all these criteria and is classified as an active product, providing continuity for applications currently using the obsolete TWM5J470.

Parameter Comparison

Engineering Selection Recommendations

The TWM5J470E is the direct equivalent for the obsolete TWM5J470. Both components are manufactured by Ohmite within the TWM series and share identical electrical specifications and physical dimensions. The primary distinction is product status and regulatory compliance: the TWM5J470E is an active product with ROHS3 compliance, whereas the TWM5J470 is obsolete and RoHS non-compliant. For new designs or component replenishment, the TWM5J470E provides full functional equivalence with improved regulatory standing.
