RSS-0509 Equivalent & Substitute Parts Reference

Part Overview

The Recom Power RSS-0509 is an obsolete DC-DC converter categorized as an isolated module, providing a single 9V output at 1W from a 4.5V to 5.5V input. With a power output of 1W, efficiency of 78%, and 1kV isolation, it was widely used for ITE (commercial) applications. As this device is obsolete, identification of an alternative model is required to ensure continuity in manufacturing and service for existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on identical electrical and mechanical parameters within the DC-DC converter category. Accepted substitutes must match the following criteria: input voltage range, output voltage, output current, output power, voltage isolation, efficiency, number of outputs, mounting type, package/case, RoHS compliance, MSL, and REACH status. No additional assumptions are made.

Parameter Comparison

Engineering Selection Recommendations

Selection is determined by the product status, RoHS/REACH compliance, and MSL. The RSS-0509 is obsolete and has been directly superseded by the R1S-0509 (active status), which maintains the same compliance certifications. Engineering selection must prioritize availability, compliance, and identical key parameters.

Frequently Asked Questions (FAQ)

Q1: What are the critical criteria for substituting the Recom Power RSS-0509?
A1: Critical criteria include input voltage range, output voltage, maximum output current, power rating, isolation voltage, efficiency, mounting type, package/case, RoHS compliance, MSL, and REACH status.

Q2: Is the Recom Power R1S-0509 compatible in terms of electrical and mechanical interface?
A2: The Recom Power R1S-0509 matches the RSS-0509 in all key electrical and mechanical parameters, including voltage inputs and outputs, isolation, package, and form factor.

Q3: How does product status affect substitute selection?
A3: The RSS-0509 is obsolete; an active equivalent is necessary to ensure continued availability for manufacturing and support.

Q4: Are there compliance concerns in switching to the R1S-0509?
A4: Both the RSS-0509 and R1S-0509 are ROHS3 compliant and REACH unaffected, ensuring compliance equivalency.

Q5: Does the mounting or package change with the substitute?
A5: Both parts utilize the 8-SMD Module, 5 Leads surface mount package, ensuring direct mechanical compatibility.
