Mitsubishi Q00UJCPU Programmable Controller, 10K Steps

The Q00UJCPU is the base CPU for the MELSEC-Q rack. It runs stored program cyclic operation with 10K steps of program capacity and supports 821 instructions. That program memory is sized for small to medium machine control—tight for a multi-axis motion program, but fine for a simple sequence. It's a mature product on the catalog; lead time typically runs 1–10 working days, so line-down replacement is not usually a sourcing headache. If you're consolidating tail spend, this is a standard preferred-supplier line—no maverick spend required.
