RSS-3.33.3/H Equivalent & Substitute Parts Reference

Part Overview

The RSS-3.33.3/H from Recom Power is an isolated DC-DC converter module, providing a single regulated 3.3V output at up to 303mA from an input range of 3V to 3.6V, with 3 kV isolation. It is designed for ITE (Commercial) and Medical applications, supporting a surface-mount configuration in a compact 8-SMD Module, 5 Leads package. This part has been declared obsolete, creating a need to identify direct substitute models that strictly adhere to the same electrical, mechanical, and regulatory specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly based on matching the following key electrical, mechanical, and compliance parameters: manufacturer, isolated module type, number of outputs, input and output voltage ranges, maximum output current, power rating, voltage isolation, application suitability (ITE and Medical), SCP feature, surface mount package, package dimensions, RoHS and REACH compliance, operating temperature, and moisture sensitivity level. Only parts that fully meet these parameters are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The RSS-3.33.3/H is classified as obsolete. R1S-3.33.3/H from Recom Power matches all fundamental electrical and mechanical parameters and maintains ROHS3 compliance, REACH unaffected status, ECCN EAR99, and MSL 1 (Unlimited). Both parts are suitable for ITE (Commercial) and Medical applications. The substitute R1S-3.33.3/H is currently in active product status, making it a direct replacement based on the criteria provided.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to select substitutes for RSS-3.33.3/H?
A1: Substitutes must match electrical parameters (input and output voltage, current, power rating, voltage isolation), mechanical features (mounting type, package, size), application compatibility, features, compliance (RoHS, REACH, ECCN, MSL), and thermal characteristics.

Q2: Are there any differences in the package dimensions between RSS-3.33.3/H and R1S-3.33.3/H?
A2: Yes, R1S-3.33.3/H is slightly wider (0.42" vs 0.32") and shorter in height (0.28" vs 0.29"), but uses the same 8-SMD Module, 5 Leads package type.

Q3: Do both parts support the same operating temperature range?
A3: R1S-3.33.3/H supports a wider range (-40°C to 100°C) compared to RSS-3.33.3/H (-40°C to 85°C).

Q4: Are both substitute parts compliant with ROHS3 and REACH?
A4: Both RSS-3.33.3/H and R1S-3.33.3/H are ROHS3 compliant and REACH unaffected.

Q5: Is there any difference in moisture sensitivity level (MSL)?
A5: No, both parts have MSL 1 (Unlimited).
