Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TWM5J2K0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2 kOhms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Metal Oxide Film
• Package configuration: Radial with 2 terminations
• Operating temperature range: -55°C ~ 275°C
• Temperature coefficient: ±350ppm/°C
• Physical dimensions: 0.492" L x 0.354" W (12.50mm x 9.00mm)
• Height - Seated (Max): 1.024" (26.00mm)

The substitute part TWM5J2K0E meets all electrical and mechanical specifications required for direct replacement. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The TWM5J2K0E is the direct equivalent substitute for the obsolete TWM5J2K0. Both components are manufactured by Ohmite and share identical electrical specifications, thermal characteristics, and physical dimensions. The TWM5J2K0E maintains active product status with higher inventory availability.

For applications requiring RoHS3 compliance, the TWM5J2K0E is the appropriate selection. The TWM5J2K0 remains available for legacy systems where RoHS non-compliant components are acceptable. Both parts carry identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can TWM5J2K0E replace TWM5J2K0 in existing designs?

A: Yes. The TWM5J2K0E is electrically and mechanically equivalent. All electrical parameters, thermal characteristics, and physical dimensions are identical. The primary differences are product status and RoHS compliance level.

Q: What is the difference between the two part numbers?

A: The TWM5J2K0 is obsolete with RoHS non-compliant status. The TWM5J2K0E is the active production equivalent with ROHS3 compliance. Both are 2 kOhms ±5% 5W radial metal oxide film resistors from Ohmite's TWM series.

Q: Are there any packaging differences?

A: The TWM5J2K0E is supplied in bulk packaging, while the TWM5J2K0 packaging designation is not specified. Both components use identical radial package configuration with the same physical dimensions and termination count.

Q: What are the critical parameters for substitution?

A: Substitution requires matching resistance value (2 kOhms), tolerance (±5%), power rating (5W), composition (metal oxide film), package type (radial), operating temperature range (-55°C ~ 275°C), and physical dimensions (0.492" L x 0.354" W, 1.024" max height).

Q: Is the TWM5J2K0 still available for purchase?

A: The TWM5J2K0 is listed as obsolete but shows 843 pieces in current inventory. The TWM5J2K0E is the active production part with 3541 pieces available, providing superior long-term supply assurance.
