REC15-243.4S/H2 Equivalent & Substitute Parts Reference

Part Overview

The Recom Power REC15-243.4S/H2 is an isolated module DC-DC converter delivering 3.4V output at up to 3A with a 15W power rating. It accepts a DC input voltage range of 18V to 36V and provides a single output. This device is designed for ITE (Commercial) applications, features remote On/Off, OCP, and SCP, and is available in a 6-DIP through-hole module package. As the REC15-243.4S/H2 series is classified as obsolete, it is necessary to identify suitable substitute models that conform to the same electrical, mechanical, and compliance parameters for maintaining legacy designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly determined by matching key electrical and mechanical parameters: type (Isolated Module), input voltage range (18V–36V), output voltage (3.4V), maximum output current (3A), total power (15W), voltage isolation (2 kV), number of outputs (1), package/case (6-DIP Module), mounting type (Through Hole), operating temperature (-40°C to 71°C), and efficiency (85%). Environmental, safety, and compliance features such as RoHS3 status and REACH compliance must also align.

Parameter Comparison

Engineering Selection Recommendations

Use of REC15-243.4S/H2/M as a substitute for REC15-243.4S/H2 is based on identical electrical, environmental, and compliance parameters as provided. Both parts are ROHS3 Compliant, have the same MSL, and are REACH Unaffected, ensuring compatibility with regulations and environmental requirements. The substitute part is currently active, ensuring continued availability.

Frequently Asked Questions (FAQ)
