Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TWM5J430 is determined by strict equivalence across the following parameters:

• Resistance value: 430 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 with maximum seated height of 1.024"

The TWM5J430E meets all substitution criteria as a direct equivalent part manufactured by Ohmite in the same TWM series.

Parameter Comparison

Engineering Selection Recommendations

The TWM5J430E is the direct substitute for the obsolete TWM5J430. Both parts are manufactured by Ohmite and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and regulatory compliance: the TWM5J430E is an active product with ROHS3 compliance, whereas the TWM5J430 is obsolete and RoHS non-compliant.

For new designs or ongoing procurement, the TWM5J430E is the appropriate selection. For legacy systems requiring the original TWM5J430, the TWM5J430E provides full functional and physical compatibility while offering improved regulatory standing.
