APC18T12-9L Equivalent & Substitute Parts Reference

Part Overview

The APC18T12-9L is a DC-DC converter manufactured by ARTESYN / Advanced Energy, categorized as a Non-Isolated Point-of-Load (PoL) Module supplying 0.75–5.5V at up to 18A output from a 10–14V input in a 75W surface-mount module. As this model is marked “Obsolete,” identification of substitute and equivalent DC-DC converter models is required to ensure continuity in existing designs and minimize supply risk.

Substitute Part Grouping Explanation

Substitute DC-DC converter models are selected strictly by matching the following parameters: type (Non-Isolated PoL Module), number of outputs (1), input voltage range (encompassing main part’s 10–14V), output voltage range (encompassing primary part’s 0.75–5.5V), minimum output current capability (≥18A), wattage (≥75W), similar package for mounting and dimensions, and ITE (Commercial) application suitability. The substitute must support surface-mount (6-SMD Module) format as provided.
