RSS-3.309 Equivalent & Substitute Parts Reference

Part Overview

The Recom Power RSS-3.309 is an isolated DC-DC converter module, providing a single 9V output at up to 111mA from a 3V to 3.6V input. Rated at 1W output power with 1kV isolation, it features surface-mount packaging, SCP (short-circuit protection), and a compact size. The product is classified as obsolete, making it necessary for engineers to identify equivalent and substitute models that match the required functional, electrical, and mechanical parameters. Selection of an alternative is essential for maintaining design continuity in applications affected by end-of-life status.

Key Parameters

Substitute Part Grouping Explanation

Substitutes for DC-DC converter isolated modules are validated strictly by matching input voltage range, output voltage, maximum output current, power rating, isolation voltage, package type, mounting method, and compliance with specified certifications. Only parts matching these key parameters are considered electrically and mechanically compatible substitutes.

The allowed parameters for substitution are:

• Input Voltage Range: 3V to 3.6V
• Output Voltage: 9V, Single Output
• Max Output Current: 111mA
• Power Rating: 1 W
• Isolation Voltage: 1 kV
• Mounting Type: Surface Mount
• Package / Case: 8-SMD Module, 5 Leads
• Environmental and Compliance: RoHS, REACH, MSL, ECCN, HTSUS

Parameter Comparison

Engineering Selection Recommendations

When selecting a substitute for the Recom Power RSS-3.309 DC-DC converter isolated module, the R1S-3.309 is confirmed as an equivalent substitute based on identical electrical parameters, package type, and compliance attributes. The substitute part meets all RoHS, REACH, and MSL certification requirements and is presently active, which addresses product continuity concerns arising from the RSS-3.309 being obsolete.
