RTS-243.3/P Equivalent & Substitute DC DC Converter Parts Reference

Part Overview

The Recom Power RTS-243.3/P is an isolated DC DC converter module with a single 3.3V output at up to 606mA, rated for 2W output power and a 21.6V to 26.4V input voltage range. This 8-SMD Module is designed for commercial ITE applications, features short circuit protection, and operates between -40°C and 85°C. The RTS-243.3/P is now classified as obsolete, necessitating the selection of functionally equivalent and mechanically compatible substitute parts for ongoing maintenance, inventory continuity, or new designs.

Key Parameters

Substitute Part Grouping Explanation

Equivalent and substitute DC DC converter parts for RTS-243.3/P are identified solely according to directly matching or exceeding key electrical and mechanical parameters: output voltage, output current, input voltage range, power rating, isolation voltage, module footprint, mounting type, and compliance (RoHS, REACH, MSL). Substitute parts must provide identical or narrower performance range in all critical parameters without deviation. Only parts with the same 8-SMD Module, output characteristics, power handling, and protection features are considered valid replacements for RTS-243.3/P.

Parameter Comparison

Engineering Selection Recommendations

RTS-243.3/P is obsolete and no longer in production. Substitute part R2S-243.3/P is active, offers identical key electrical and mechanical parameters, and maintains equivalent RoHS, moisture sensitivity level, and REACH compliance. Substitution ensures direct compatibility in applications requiring continued regulatory adherence and supply stability.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria for selecting a substitute for RTS-243.3/P DC DC converter?
A1: Substitution requires identical output voltage, output current capacity, input voltage range, power rating, isolation voltage, package, mounting style, and compliance certifications.

Q2: Is R2S-243.3/P directly compatible in terms of footprint and mounting?
A2: Both RTS-243.3/P and R2S-243.3/P use the 8-SMD Module, 5 Leads package for surface mounting. Basic footprint compatibility is maintained with minor dimensional differences.

Q3: Does the difference in package dimension between RTS-243.3/P and R2S-243.3/P affect their substitutability?
A3: The width of R2S-243.3/P is slightly larger (10.7mm vs 9.3mm), but all other critical package details including pin configuration and height are retained within the 8-SMD Module standard.

Q4: Are compliance and certifications matched between RTS-243.3/P and R2S-243.3/P?
A4: Both products are ROHS3 Compliant, have Moisture Sensitivity Level 1 (Unlimited), and are REACH Unaffected.

Q5: Should other part candidates be considered if only these specific parameters are required?
A5: Based on the provided input, only R2S-243.3/P meets the strict substitution criteria for RTS-243.3/P. No additional part numbers are listed as permitted substitutes.
