RSS-3.33.3/P Equivalent & Substitute Parts Reference

Part Overview

RSS-3.33.3/P is an isolated module DC-DC converter from Recom Power, classified under the ECONOLINE RSS (1W) series. It delivers a single regulated 3.3V output at a maximum current of 303mA, accepting input voltages from 3V to 3.6V and providing a power rating of 1W. The converter is designed for ITE (Commercial) applications, includes short-circuit protection (SCP), and features 1kV isolation voltage. The product is surface-mounted in an 8-SMD Module with 5 leads and supports operation from -40°C to 85°C. Currently, RSS-3.33.3/P holds "Obsolete" status, necessitating the identification of direct substitute parts to ensure ongoing production and maintenance for systems utilizing this product.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection for RSS-3.33.3/P is determined by matching the following parameters: input voltage range (3V to 3.6V), output voltage (3.3V), output current (303mA), power rating (1W), isolation voltage (1kV), mounting type (surface mount), package/case (8-SMD Module, 5 Leads), and compliance standards including RoHS3, MSL 1, and REACH. Substitute parts must fulfill all these requirements to ensure full compatibility and uninterrupted function in replacement scenarios.

Parameter Comparison

Engineering Selection Recommendations

As RSS-3.33.3/P is marked Obsolete, an active substitute part is required for ongoing applications. Substitute selection should prioritize active status, identical regulatory and environmental certifications (RoHS3, REACH, MSL 1), and consistent electrical and mechanical specifications as provided. R1S-3.33.3/P from Recom Power matches all these criteria.
