Equivalent & Substitute Parts for PMH8318TP

Part Overview

The Flex Power Modules PMH8318TP is an obsolete non-isolated Point-of-Load (PoL) DC-DC converter module designed for ITE (Commercial) applications. It features a single adjustable output (0.8–1.8V), a maximum output current of 18A, and operates from a 10.8V to 13.2V input. Due to its obsolete status, it is necessary to find alternative models with matching electrical and mechanical key parameters for new designs or maintenance needs.

Substitute Part Grouping Explanation

Substitutions for PMH8318TP are grouped strictly based on matching the following key parameters: type (non-isolated PoL module), number of outputs (1), input voltage range (10.8V–13.2V), output voltage range (0.8V–1.8V), maximum output current (18A), compatible package and mounting (10-DIP Module, through hole), operating temperature range (up to 85°C), and compliance with ROHS3 and REACH. Only parts matching these explicit characteristics are considered interchangeable within this product category.
