RSS-1209/HP Equivalent & Substitute Parts Reference
Part Overview
The RSS-1209/HP is an isolated DC-DC converter module manufactured by Recom Power. It delivers a single 9V output at 111mA from a 10.8V to 13.2V input, providing 1W of power with a 3kV isolation rating. The device is intended for ITE (commercial) and medical applications, featuring short circuit protection (SCP), ROHS3 compliance, and surface mount packaging with a compact 8-SMD module, 5-lead case. This model is now classified as obsolete, creating a necessity for identifying alternative models to support new designs and ongoing maintenance requirements.

Engineering Selection Recommendations
R1S-1209/HP matches all required electrical parameters and regulatory compliances of the obsolete RSS-1209/HP. Both components are ROHS3 compliant, have MSL 1 (unlimited) and are REACH unaffected. The active product status of R1S-1209/HP makes it suitable as a substitute for the discontinued RSS-1209/HP, considering all provided criteria.
Frequently Asked Questions (FAQ)
Q: What are the primary parameters that must match when selecting a substitute for RSS-1209/HP?
A: The substitute must have matching input voltage range, output voltage and current, power rating, isolation voltage, number of outputs, package type, regulatory compliance (ROHS3, REACH), mounting method, and protection features.
Q: Are R1S-1209/HP and RSS-1209/HP mechanically compatible?
A: Both parts use an 8-SMD Module with 5 leads and are surface mount types; however, there is a difference in package width and height dimensions as shown in the comparison table.
Q: Does the substitute R1S-1209/HP support the same applications as RSS-1209/HP?
A: Yes, both are suitable for ITE (Commercial) and Medical applications.
Q: Are there differences in qualification or compliance between these two parts?
A: Both parts are ROHS3 compliant, have MSL 1 (Unlimited), and are REACH unaffected.
Q: Does the substitute part have a wider operating temperature range?
A: The R1S-1209/HP supports an operating temperature range of -40°C to 100°C, compared to -40°C to 85°C for RSS-1209/HP, which meets or exceeds the original specification.
