Substitution eligibility for the TWM5J56R is determined by strict equivalence across the following parameters:

• Resistance value: 56 Ohms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Metal Oxide Film
• Package configuration: Radial
• Operating temperature range: -55°C to 275°C
• Temperature coefficient: ±350ppm/°C
• Physical dimensions and termination count

The TWM5J56RE qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction between these components is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The TWM5J56RE is the direct equivalent for the obsolete TWM5J56R. Both components share identical electrical specifications, thermal characteristics, and physical dimensions, ensuring functional interchangeability in circuit applications.

The primary advantage of selecting TWM5J56RE is its active product status, ensuring continued availability and supply chain reliability. Additionally, TWM5J56RE meets ROHS3 compliance requirements, whereas the original TWM5J56R does not. For applications subject to RoHS regulations or environmental compliance mandates, TWM5J56RE is the appropriate selection.

Both components maintain identical REACH and ECCN classifications, confirming regulatory equivalence for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can TWM5J56RE be used as a direct replacement for TWM5J56R?

A: Yes. Both components are electrically and mechanically identical, with matching resistance values, tolerance, power ratings, temperature coefficients, and physical dimensions. The radial package configuration and termination count are identical.

Q: What is the difference between TWM5J56R and TWM5J56RE?
