Product status and compliance
The Siemens 3VU9135-1BB00 carries an NRND (Not Recommended for New Design) lifecycle status, meaning the manufacturer has flagged it for eventual phase-out. New projects should not specify this terminal; existing BOM lines may continue to source it through independent channels while supply lasts.
Sourcing posture
Volume buyers should factor in the NRND timeline and plan a transition to a recommended replacement before the terminal becomes unavailable.
