RTS-123.3/H Equivalent & Substitute Parts Reference

Part Overview

The Recom Power RTS-123.3/H is an isolated DC-DC converter module providing a single 3.3V output at up to 606mA with a 2W power rating. It accepts an input voltage range of 10.8V to 13.2V and features a 3 kV isolation rating. Housed in an 8-SMD Module, 5 Leads surface mount package, this product is designed for ITE (Commercial) and Medical applications, offering protections such as short-circuit protection (SCP). As this model is now classified as obsolete, it is necessary to identify alternative models that match its electrical and mechanical parameters for use in both new and existing designs.

Key Parameters

Substitute Part Grouping Explanation

Eligible substitute DC-DC converter modules must match all critical electrical and mechanical parameters of the RTS-123.3/H. These key parameters include input voltage range (10.8V–13.2V), output voltage (3.3V), maximum output current (606mA), power rating (2 W), isolation voltage (3 kV), surface mount packaging (8-SMD Module, 5 Leads), dimensions, and compliance certifications (RoHS, REACH). Substitute selections consider identical or improved operational characteristics within these constraints. Only parts explicitly matching these parameters are listed as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Component engineering selection for the RTS-123.3/H must prioritize product status, compliance, and certification alignment. The RTS-123.3/H is obsolete; the R2S-123.3/H is active, maintains identical RoHS3 and REACH compliance, and holds the same ECCN and HTSUS designations. Selection for replacement is supported by the matching key parameters and compliance criteria specified in the product documentation.

Frequently Asked Questions (FAQ)

Q: What parameters must match to substitute the RTS-123.3/H DC-DC converter?
A: All critical parameters must match, including input voltage range, output voltage, output current, output power, isolation voltage, mounting type, package/case, and regulatory compliance (RoHS, REACH, ECCN, HTSUS).

Q: Is the R2S-123.3/H a form-fit-function replacement for the RTS-123.3/H?
A: The R2S-123.3/H matches all major electrical characteristics and compliance certifications. The dimensions are nearly identical, with only minor width variation.

Q: Are there any differences in the package or mounting style between the main and substitute parts?
A: Both parts use the 8-SMD Module, 5 Leads surface mount package. The R2S-123.3/H is slightly wider at 0.42" compared to 0.37" for the RTS-123.3/H.

Q: Is the R2S-123.3/H suitable for medical and ITE (commercial) applications like the original?
A: Both parts list ITE (Commercial) and Medical as eligible applications.

Q: What compliance or environmental certifications are met by both parts?
A: Both RTS-123.3/H and R2S-123.3/H are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99.
