No successor part number is published. For procurement, that means standard lead times apply — no urgency to stockpile, no cross-reference hunt needed yet.
The part description reads ABB 2TLA050202R1223 LINESTRONG2Z, 2 — the LINESTRONG2Z series is ABB's safety product line, typically used in guarding and hazard-zone applications. No further functional specs (voltage, current, IP rating) are listed in this record, so the fit depends on the existing safety circuit design.
