RSS-0505/H Equivalent & Substitute Parts Reference

Part Overview

The RSS-0505/H is a Recom Power DC-DC converter module providing isolated output specifically designed for ITE (Commercial) and Medical applications. It delivers 1W of power at a regulated 5V output from a 4.5V–5.5V input, with a single output channel and 3kV isolation. The product status is obsolete, making identifying alternative or substitute part numbers essential for continued designs or repairs requiring these precise specifications.

Engineering Selection Recommendations

The RSS-0505/H is obsolete; the R1S-0505/H is an active alternative with equivalent electrical, compliance, and package parameters. Both part numbers are ROHS3 compliant, have MSL 1 (Unlimited), and REACH Unaffected status. Selection may be based strictly on product status and regulatory compliance as provided in the parameter list.

Frequently Asked Questions (FAQ)

Q1: What parameters must match when selecting a substitute for RSS-0505/H?
A1: Input voltage range, output voltage/current, power rating, isolation voltage, mounting type, package/case, application type, operating temperature, and compliance certifications.

Q2: Is R1S-0505/H mechanically compatible with designs using RSS-0505/H?
A2: Both devices use the 8-SMD Module, 5 Leads package. Dimensions differ in width and height, so mechanical fit must correspond to these dimensions.

Q3: Are safety and compliance attributes equivalent?
A3: Both RSS-0505/H and R1S-0505/H are ROHS3 compliant, MSL 1 (Unlimited), and REACH Unaffected.

Q4: Does the substitute have the same operating temperature range?
A4: R1S-0505/H supports an extended operating temperature of -40°C ~ 100°C, which includes and exceeds the range for RSS-0505/H (-40°C ~ 85°C).

Q5: Can the substitute be used in identical application categories?
A5: Both parts are designated for ITE (Commercial) and Medical applications as per the provided data.
