Parameter Comparison

Engineering Selection Recommendations

The LM5106MMX/NOPB is the direct substitute for the obsolete LM5106MMX. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product lifecycle status and compliance certification. The LM5106MMX carries obsolete status with RoHS non-compliant certification, while the LM5106MMX/NOPB maintains active product status with ROHS3 compliance. The LM5106MMX/NOPB is available in Cut Tape and Digi-Reel packaging formats, supporting both manual and automated assembly workflows.

For new designs or production continuity, the LM5106MMX/NOPB is the appropriate selection. For legacy system maintenance where the original LM5106MMX is specified, the LM5106MMX/NOPB provides full electrical and mechanical compatibility with enhanced compliance status.
