Recom Power RTS-243.3 Equivalent & Substitute Parts Reference

Part Overview

The Recom Power RTS-243.3 is an isolated DC-DC converter module, providing 3.3V output at 606mA from a 21.6V–26.4V input. It delivers 2W, features 1kV isolation, single output, and is designed for ITE (Commercial) applications. The part status is obsolete, requiring the identification of substitute models for continued design-in or field maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified strictly based on matching the following key parameters: input voltage range, output voltage, output current, power rating, isolation voltage, number of outputs, package type, mounting type, features, operational temperature range, compliance status (RoHS, REACH), and form factor. Only parts meeting every specified criterion are listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The RTS-243.3 is marked obsolete; the R2S-243.3 is an active, ROHS3 compliant, REACH unaffected substitute part. Both entries share identical ECCN, HTSUS, and Moisture Sensitivity Level ratings. Substitute selection is confirmed solely by product status, compliance information, and certifications referenced.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine equivalency for DC-DC converter substitutes?
A1: Equivalency is determined by matching input voltage range, output voltage, output current, power rating, isolation voltage, number of outputs, mounting type, package type, feature set, operating temperature, and regulatory compliance.

Q2: Are package dimensions compatible between RTS-243.3 and R2S-243.3?
A2: Both parts use 8-SMD Module, 5 Leads with similar overall dimensions. Variations in width should be considered for mechanical fit.

Q3: Does the substitute R2S-243.3 meet the same environmental and compliance standards?
A3: R2S-243.3 is ROHS3 compliant, REACH unaffected, same as RTS-243.3, and shares the same ECCN and HTSUS codes.

Q4: Can thermal performance be directly compared?
A4: Both parts provide equivalent electrical output at the same power rating. R2S-243.3 features an expanded operating temperature range, covering the full range of RTS-243.3.

Q5: Does the mounting type need verification when substituting?
A5: Both parts are surface mount and specified in 8-SMD Module, 5 Leads format. Compatibility with the target PCB footprint is maintained within defined parameters.
