Parameter Comparison

Engineering Selection Recommendations

The TWM3J100E is the direct substitute for the obsolete TWM3J100. Both components share identical electrical specifications and mechanical form factors, enabling pin-for-pin replacement in existing circuit designs.

The primary distinction between the two parts is product status and regulatory compliance. The TWM3J100 is obsolete and RoHS non-compliant, while the TWM3J100E maintains active production status and achieves ROHS3 compliance. For new designs or applications subject to RoHS regulations, the TWM3J100E is the appropriate selection. For legacy system maintenance where RoHS compliance is not required, either part satisfies the functional requirements.

Both components carry identical REACH and ECCN classifications, ensuring consistent export and supply chain handling.
