Technical Dossier
The Allen-Bradley SP-142129 (Rockwell Automation part 135232-04) is a replacement power supply kit designed for the 1746 SLC 500 modular controller platform — one of the most widely deployed PLCs across discrete manufacturing, material handling, and process automation environments. Despite the SLC 500 platform entering its mature lifecycle phase, millions of installed units remain in active service globally, creating sustained and often urgent demand for genuine spare parts.
For procurement managers, the core challenge is not whether to source this part — it is how to source it without overpaying, accepting counterfeit components, or accepting unacceptable lead times that trigger unplanned downtime. This page is designed to answer those questions directly.

Procurement decisions for legacy PLC spare parts are rarely straightforward. The SP-142129 135232-04 sits in a category where the cost of not having the part vastly exceeds the cost of the part itself. A single hour of unplanned downtime on an SLC 500-controlled line can cost a mid-size manufacturer between USD $5,000 and $50,000 depending on the sector.
