RSS-3.309/P Equivalent & Substitute Parts Reference

Part Overview

The Recom Power RSS-3.309/P is an isolated DC-DC converter module designed for ITE (Commercial) applications. It features a single output of 9V with a maximum output current of 111mA and input voltage range of 3V to 3.6V. With a power rating of 1W and 1kV isolation, this module supports surface mount installation and complies with ROHS3 and REACH standards. The RSS-3.309/P is classified as obsolete, making it necessary to identify alternative and substitute models that fulfill identical electrical and mechanical requirements for continued system integration or maintenance purposes.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection for DC-DC converters in the isolated module product category requires strict parameter matching to ensure electrical and mechanical compatibility. Substitution is based only on the parameters provided: input voltage range, output voltage and current, isolation, mounting type, package, dimensions, compliance, and application category. These ensure cross-compatibility in re-design or maintenance without inferential modifications. Only parts matching these parameters are considered direct substitutes.

Key parameters used for grouping:

• Voltage - Input (Min) & (Max)
• Voltage - Output 1 & Current - Output (Max)
• Power (Watts)
• Voltage - Isolation
• Operating Temperature
• Efficiency
• Mounting Type and Package / Case
• Size / Dimension
• RoHS and REACH status
• Applications
• Features
• Product Status

Parameter Comparison

Engineering Selection Recommendations

Selection between RSS-3.309/P and R1S-3.309/P is governed primarily by product status and compliance certifications. RSS-3.309/P is obsolete, while R1S-3.309/P is active with ROHS3 and REACH compliance and an identical operational profile. Given matching certifications and mechanical standards, R1S-3.309/P is an acceptable substitute strictly within the provided criteria.

Frequently Asked Questions (FAQ)

Q: What substitution criteria are used for DC-DC converter isolated module replacements?
A: Only parameters provided—input voltage range, output voltage/current, isolation rating, package specifications, size, compliance, and application classification—are used.

Q: Is R1S-3.309/P compatible with designs using RSS-3.309/P?
A: R1S-3.309/P conforms to all specified electrical, mechanical, and compliance parameters detailed for RSS-3.309/P.

Q: Are there dimensional differences requiring layout changes?
A: R1S-3.309/P and RSS-3.309/P share the same length; minor differences in width (0.32” vs. 0.42”) and height (0.29” vs. 0.28”) must be verified for mechanical fit within the application envelope.

Q: Does the mounting type and package remain consistent between RSS-3.309/P and R1S-3.309/P?
A: Both are specified as 8-SMD Module, 5 Leads for surface mount applications.

Q: Do compliance statuses (RoHS3, REACH, MSL) differ between parts?
A: Both RSS-3.309/P and R1S-3.309/P are ROHS3 compliant, REACH unaffected, and rated with MSL 1 (Unlimited).
