Recom Power RSS-0524 Equivalent & Substitute Parts Reference

Part Overview

The Recom Power RSS-0524 is an isolated DC-DC converter module categorized in the 1W ECONOLINE RSS series. It delivers a single output of 24V at a maximum load of 42mA from a 4.5V to 5.5V input range. With a surface-mount 8-SMD module (5 leads), it features SCP (short circuit protection), 1 kV isolation voltage, and efficiency of 84%. It is RoHS3 compliant and suited for commercial ITE applications. The RSS-0524 has reached an obsolete product status, necessitating identification of direct substitute models to ensure ongoing designs, repairs, or maintenance remain supported.

Key Parameters

Substitute Part Grouping Explanation

Substitute eligibility is determined by matching the following electrical and mechanical parameters: input voltage range (4.5V–5.5V), output voltage (24V), maximum output current (42mA), output power rating (1W), isolation voltage (1 kV), number of outputs (1), protection features, efficiency rating, mounting type (surface mount), and package/case dimensions. Compliance with ROHS and REACH status is also required. Product status is considered to ensure ongoing availability.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts for RSS-0524 must be based on full electrical and mechanical parameter alignment as detailed above. R1S-0524 matches all specified critical parameters, maintains ROHS3 compliance, and retains REACH unaffected status. R1S-0524 has an "Active" product status, which supports forward-looking design and procurement requirements. Certifications and inventory status provided further support direct substitution.

Frequently Asked Questions (FAQ)

Q1: What are the mandatory criteria for selecting a substitute for RSS-0524?
A1: Eligible substitutes must precisely match all key electrical (input/output voltage and current, isolation, efficiency, protection) and mechanical (mounting, package, size) parameters and carry equivalent compliance certifications.

Q2: How does product status affect substitute selection?
A2: Obsolete components like RSS-0524 require substitutes that are actively manufactured and stocked, ensuring continued availability and support.

Q3: Are package differences between RSS-0524 and substitutes allowable for substitution?
A3: Package/case form factor and mounting type must be identical for direct substitution unless explicitly approved by the design specification.

Q4: Is the R1S-0524 a direct substitute for RSS-0524?
A4: Yes, R1S-0524 matches all electrical, mechanical, and compliance parameters, and has an active product status.

Q5: Does ROHS3 compliance affect substitute eligibility?
A5: Only substitutes with matching ROHS3 and REACH compliance are eligible per the selection criteria.

Q6: Is the operating temperature range of R1S-0524 compatible with RSS-0524?
A6: R1S-0524 supports a wider operating temperature range, which includes the range for RSS-0524, ensuring compatibility within the original specified limits.
