Key Parameters

Substitute Part Grouping Explanation

Substitution of the TWM3J3K0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 3 kOhms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Metal Oxide Film
• Package configuration: Radial with 2 terminations
• Physical dimensions: 0.492" L x 0.354" W, 1.024" seated height
• Operating temperature range: -55°C to 275°C
• Temperature coefficient: ±350ppm/°C

The TWM3J3K0E maintains complete electrical and mechanical compatibility with the original part, differing only in product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The TWM3J3K0E is the direct substitute for the obsolete TWM3J3K0. Both components are manufactured by Ohmite and share identical electrical specifications and physical dimensions. The primary distinction is product lifecycle status: the TWM3J3K0 is obsolete, while the TWM3J3K0E maintains active production status.

For new designs or production continuity, the TWM3J3K0E is the appropriate selection. The TWM3J3K0E additionally provides ROHS3 compliance, whereas the original TWM3J3K0 is RoHS non-compliant. Both components are REACH Unaffected and classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can TWM3J3K0E be used as a direct replacement for TWM3J3K0?

A: Yes. The TWM3J3K0E is electrically and mechanically identical to the TWM3J3K0. All critical parameters—resistance, tolerance, power rating, composition, package type, dimensions, and operating temperature range—are equivalent. The primary difference is product status and RoHS compliance.

Q: What is the difference between TWM3J3K0 and TWM3J3K0E?

A: The TWM3J3K0 is classified as obsolete, while the TWM3J3K0E is active. The TWM3J3K0E is ROHS3 compliant, whereas the TWM3J3K0 is RoHS non-compliant. Packaging differs: TWM3J3K0 uses standard packaging, while TWM3J3K0E is supplied in bulk. Electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.492" L x 0.354" W (12.50mm x 9.00mm) with a maximum seated height of 1.024" (26.00mm). Radial lead configuration and termination count are identical.

Q: What is the operating temperature range?

A: Both the TWM3J3K0 and TWM3J3K0E operate from -55°C to 275°C with a temperature coefficient of ±350ppm/°C.

Q: Is RoHS compliance a factor in substitution?

A: RoHS compliance status differs between the two parts. The TWM3J3K0E is ROHS3 compliant, while the TWM3J3K0 is non-compliant. For applications requiring RoHS compliance, the TWM3J3K0E is the appropriate selection.
