MicroLogix lifecycle status varies by model. Several families have been discontinued, while the 1400 has been listed as Active Mature. Do not assume the whole MicroLogix range has a single end-of-sale date.

Successors and migration considerations
- Allen-Bradley MicroLogix 1000 (1761): Micro800 (Rockwell MicroLogix to Micro800 modernisation guide)
- Allen-Bradley MicroLogix 1100 (1763): Micro800
- Allen-Bradley MicroLogix 1200 (1762): Micro800
- Allen-Bradley MicroLogix 1400 (1766): Micro800 (Rockwell lists a replacement)
- Allen-Bradley MicroLogix 1500 (1764): Micro800 or CompactLogix
Migration is an engineering assessment, not an automatic drop-in substitution. Check program conversion, field wiring, communications, safety and commissioning requirements.

Inventory changes as items are sold and new consignments arrive, so we do not publish fixed quantities or condition claims on these reference guides.
Questions engineers ask
Does discontinued mean an installed controller must be replaced immediately?
No. It means the product's commercial lifecycle has changed, not that every installed unit has stopped functioning. Review spares availability, reliability, risk and your maintenance strategy.
Can Automation Outlet help source a legacy spare?
Yes. Send us the exact manufacturer part number, revision or series, quantity and required condition. Availability and testing status must be confirmed before an order.
Can a listed successor be swapped directly into my system?
Not necessarily. Replacement can require changes to software, wiring, communications, safety assessments and commissioning. Confirm compatibility with manufacturer documentation.
