REC15-483.4S/H3 Equivalent & Substitute Parts Reference

Part Overview

The REC15-483.4S/H3 from Recom Power is an isolated DC-DC converter designed for ITE (Commercial) applications. It delivers 3.4V output at up to 3A with a power rating of 15W, accepting input voltages from 36V to 75V. The part features remote on/off, OCP (overcurrent protection), and SCP (short-circuit protection), with efficiency rated at 85%. The REC15-483.4S/H3 is classified as obsolete, necessitating the identification of alternative models meeting identical electrical, mechanical, and regulatory specifications to maintain design compatibility and supply continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection is conducted strictly on the basis of matching key technical parameters, regulatory compliance, and mechanical compatibility. The critical matching criteria include: DC-DC converter isolated module type, single output, identical input voltage range (36V – 75V), output voltage (3.4V), output current (3A), power rating (15W), voltage isolation (3 kV), package dimensions, mounting type (through hole, 6-DIP module), control features, and operating temperature range. RoHS and REACH compliance, as well as inventory status, are also included as strict selection parameters.

Parameter Comparison

Engineering Selection Recommendations

The main part, REC15-483.4S/H3, has been designated as obsolete. The substitute part, REC15-483.4S/H3/M, is currently active and maintains identical electrical, mechanical, and package parameters, while also being ROHS3 compliant and REACH unaffected. For continuity in production and inventory purposes, a transition to REC15-483.4S/H3/M provides compliance with all defined certifications and environmental standards as specified in the provided parameter list.
