RSS-3.312/P Equivalent & Substitute Parts Reference

Part Overview

The Recom Power RSS-3.312/P is an isolated module DC-DC converter designed to convert DC input voltages between 3V and 3.6V to a single 12V output at a maximum current of 84mA with an output power of 1W. The unit provides 1kV isolation and features short-circuit protection (SCP). It is built for surface mounting, with a compact 8-SMD package and is intended for ITE (commercial) applications. The RSS-3.312/P is classified as obsolete, making it necessary to identify alternative, functionally equivalent models to ensure ongoing supply and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitutes for the RSS-3.312/P are determined strictly by matching the following parameters: input voltage range (3V - 3.6V), output voltage (12V), maximum output current (84mA), output power (1W), number of outputs (1), isolation voltage (1kV), features (SCP), mounting type (surface mount), and compliance (ROHS3, REACH). The substitute must be an isolated module in a compatible surface-mount package with equivalent or better operating temperature, efficiency, and other listed features.

Parameter Comparison

Engineering Selection Recommendations

The RSS-3.312/P is classified as obsolete. The R1S-3.312/P from Recom Power is an active product, meeting all critical electrical, mechanical, and compliance parameters including ROHS3 and REACH. Both parts provide the required moisture sensitivity level (MSL 1 - Unlimited). No variations in product status, compliance, or certifications are present between the parts that would restrict direct substitution.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria for selecting equivalent DC-DC converter substitutes?
A1: Essential criteria include matching input voltage range (3V - 3.6V), output voltage (12V), maximum output current (84mA), output power (1W), isolation voltage (1kV), number of outputs, mounting type, features, and RoHS/REACH compliance status.

Q2: Are there any differences in package dimensions between the RSS-3.312/P and R1S-3.312/P?
A2: Both parts share the same package type (8-SMD Module, 5 Leads) but have minor differences in width and height. Confirm fit within the intended PCB footprint and enclosure.

Q3: Is the substitute part compatible in terms of environmental and compliance certifications?
A3: Yes, both the RSS-3.312/P and the R1S-3.312/P are ROHS3 compliant and REACH unaffected.

Q4: Can the R1S-3.312/P be used in applications previously qualified for the RSS-3.312/P?
A4: All relevant parameters required for functional equivalence are matched or exceeded, including isolation, efficiency, and operating temperature range.

Q5: How does the product status affect engineering selection?
A5: RSS-3.312/P is obsolete; R1S-3.312/P is active. Selection of an active product ensures supply continuity.
