Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TWM5J150 is determined by strict equivalence across the following critical parameters:

• Resistance value: 150 Ohms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Metal Oxide Film
• Package configuration: Radial through-hole
• Operating temperature range: -55°C to 275°C
• Temperature coefficient: ±350ppm/°C
• Physical dimensions and height specifications

Parts meeting all these criteria are classified as direct substitutes. The TWM5J150E qualifies as a direct equivalent substitute, maintaining identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TWM5J150E is the direct substitute for the obsolete TWM5J150. Both components are manufactured by Ohmite and share identical electrical and mechanical specifications, ensuring drop-in compatibility in circuit applications.

The primary distinction between these parts is product status and regulatory compliance. The TWM5J150E carries Active product status, ensuring ongoing availability and manufacturer support. Additionally, the TWM5J150E achieves ROHS3 compliance, whereas the original TWM5J150 is RoHS non-compliant. For applications subject to RoHS regulations or requiring components with current compliance certifications, the TWM5J150E is the appropriate selection.

Both components maintain REACH Unaffected status and share identical ECCN and HTSUS classifications, confirming their regulatory equivalence for export and trade purposes.

Frequently Asked Questions (FAQ)

Q: Can the TWM5J150E be used as a direct replacement for the TWM5J150?

A: Yes. The TWM5J150E is a direct substitute. Both components share identical resistance values, tolerance, power rating, composition, package type, operating temperature range, temperature coefficient, and physical dimensions. No circuit modifications or design changes are required.

Q: What is the primary reason to transition from TWM5J150 to TWM5J150E?

A: The TWM5J150 is classified as obsolete, making long-term availability uncertain. The TWM5J150E is an active product with confirmed manufacturer support and availability. Additionally, the TWM5J150E meets ROHS3 compliance requirements, whereas the original part does not.
