RSS-3.305/P Equivalent & Substitute Parts Reference

Part Overview

The Recom Power RSS-3.305/P is an isolated DC-DC converter module designed for ITE (Commercial) applications, offering 1W output power with a single output of 5V at up to 200mA current. It accepts an input voltage range of 3V to 3.6V and features short circuit protection (SCP) with 1kV isolation. The RSS-3.305/P is classified as obsolete, making it necessary to identify alternative models with matching electrical and mechanical parameters for replacement purposes.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching electrical and mechanical parameters: number of outputs, input voltage range, output voltage, output current, output power, isolation voltage, short circuit protection (SCP), efficiency, operating temperature range, mounting type, package/case format, physical dimensions, and compliance (RoHS, REACH, MSL). Only parts meeting all these required characteristics can be considered valid substitutes for the RSS-3.305/P in DC-DC converter applications.

Parameter Comparison

Engineering Selection Recommendations

The RSS-3.305/P is classified as obsolete and is no longer in active production; its compliance status remains ROHS3 Compliant and REACH Unaffected, with Moisture Sensitivity Level 1 (Unlimited). The suggested direct substitute, R1S-3.305/P, is currently active, matches all mandatory electrical, mechanical, and compliance parameters, and maintains ROHS3 and REACH status with equivalent MSL. No additional certifications are required; selection is based on matching compliance and product status.

Frequently Asked Questions (FAQ)

Q: Which parameters are mandatory for selecting a substitute for RSS-3.305/P?
A: Substitution requires matching the number of outputs, input voltage range, output voltage, maximum output current, output power, isolation voltage, short circuit protection (SCP), efficiency, operating temperature range, mounting type, package/case format, size/dimension, and compliance (RoHS, REACH, MSL).

Q: Is R1S-3.305/P a direct mechanical fit replacement for RSS-3.305/P?
A: Both are surface-mount modules using an 8-SMD, 5-lead package. Slight dimensional differences exist; confirm fit for footprint and physical clearance in the specific PCB layout.

Q: Does the substitute part maintain equivalent performance and compliance status?
A: R1S-3.305/P provides all electrical performance matches and retains ROHS3 Compliant, REACH Unaffected, and MSL 1 (Unlimited) status.

Q: Should operating temperature differences be considered?
A: The substitute offers an extended operating range (-40°C ~ 100°C vs. -40°C ~ 85°C) while all other criteria remain consistent.

Q: Are packaging differences relevant for substitution?
A: RSS-3.305/P packaging is unspecified; R1S-3.305/P is supplied in tube form. Packaging selection should match assembly line requirements.
