Parameter Comparison

Engineering Selection Recommendations

The OP191GSZ-REEL is the direct substitute for the obsolete OP191GS-REEL. Both components share identical electrical performance specifications, functional characteristics, and physical packaging requirements. The primary distinction is product status: the OP191GS-REEL is obsolete, while the OP191GSZ-REEL maintains active production status.

The OP191GSZ-REEL is RoHS3 compliant and REACH unaffected, providing regulatory compliance for current manufacturing standards. The substitute part is available in Tape & Reel packaging format, suitable for automated assembly processes.

Selection of the OP191GSZ-REEL for new designs or production continuity is based on complete electrical and mechanical equivalence with the original OP191GS-REEL specification, combined with active product availability and regulatory compliance status.
