Parameter Comparison

Engineering Selection Recommendations

The TWM5J100E is the direct substitute for the obsolete TWM5J100. Both components are manufactured by Ohmite and share identical electrical specifications, thermal characteristics, and physical dimensions.

The primary distinction is product status and regulatory compliance. The TWM5J100E maintains active production status, ensuring long-term availability. Additionally, the TWM5J100E achieves ROHS3 compliance, whereas the original TWM5J100 is RoHS non-compliant. Both components maintain REACH Unaffected status and share identical ECCN and HTSUS classifications.

For new designs and production applications, the TWM5J100E is the appropriate selection. For legacy system maintenance requiring exact part matching, the TWM5J100E provides functional and mechanical equivalence with improved regulatory standing.
