Equivalent & Substitute Parts Reference for RSS-1205-R

Part Overview

The Recom Power RSS-1205-R is an isolated DC DC converter module designed for ITE (Commercial) applications. It delivers a single, regulated 5V output at up to 200mA with input voltage range between 10.8V and 13.2V. The device features 1kV isolation, integrated SCP (short circuit protection), and is housed in a compact 8-SMD surface-mount package. RSS-1205-R is obsolete, making it necessary to identify direct substitutes that conform to its electrical, mechanical, and compliance specifications for new designs or maintenance of existing systems.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on identical or matching electrical and mechanical parameters. Criteria include input voltage range, output voltage and current, isolation voltage, operating temperature, package type, efficiency, regulatory compliance (RoHS, REACH), and application suitability. Compatibility requires equivalence in mounting type and package dimensions to ensure direct replaceability. Only parts matching these parameters are considered valid substitutes.

Engineering Selection Recommendations

Select substitute DC DC converter modules that strictly match the obsolete RSS-1205-R in electrical specifications, mechanical compatibility, and compliance status. R1S-1205-R maintains all regulatory certifications (RoHS3 Compliant, REACH Unaffected), shares the same mounting type, and conforms to critical operational and functional requirements. Substitution is supported by the part’s active status and matching isolation, input/output, and power parameters.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for selecting a substitute for RSS-1205-R?
A1: The primary criteria include matching input and output voltages, output current, isolation voltage, mounting type, package/case, efficiency, operating temperature range, and compliance status.

Q2: Is package compatibility important in substitution?
A2: Yes. Substitute parts must match the surface mount 8-SMD package, lead count, and similar dimensions to ensure mechanical interchangeability.

Q3: Can the substitute R1S-1205-R be used in all applications supported by RSS-1205-R?
A3: R1S-1205-R meets all specified electrical and mechanical parameters and extends support to ITE (Commercial) and Medical applications.

Q4: Does compliance status affect substitution of DC DC converters?
A4: Parts must be RoHS3 compliant and REACH unaffected to meet global environmental and regulatory requirements for substitution.

Q5: Are there differences in operating temperature between RSS-1205-R and R1S-1205-R?
A5: R1S-1205-R offers a wider operating temperature range (-40°C ~ 100°C) compared to RSS-1205-R (-40°C ~ 85°C), ensuring compatibility within the original specification.

Q6: Is efficiency matched between the RSS-1205-R and R1S-1205-R?
A6: Both parts list an efficiency of 78%, supporting direct substitution in power-sensitive applications.

Q7: Is mechanical dimension a substitution constraint?
A7: Both modules share the same length and height, with minor variance in width. Verifying footprint compatibility is necessary for direct mounting.
