Engineering Selection Recommendations

The R1S-2412/P is the direct functional equivalent and recommended substitute for the obsolete RSS-2412/P. Both components are manufactured by Recom Power and maintain identical electrical specifications across all critical parameters: input voltage range (21.6V to 26.4V), output voltage (12V), output current capacity (84mA), power rating (1W), isolation voltage (1 kV), and efficiency (80%).

The R1S-2412/P offers the following advantages:

Product Status: The R1S-2412/P maintains Active product status, ensuring continued availability and manufacturer support, whereas the RSS-2412/P is classified as Obsolete.

Temperature Performance: The R1S-2412/P extends the maximum operating temperature to 100°C compared to 85°C for the RSS-2412/P, providing enhanced thermal margin for applications operating at elevated ambient conditions.

Compliance: Both components maintain ROHS3 compliance, MSL 1 moisture sensitivity rating, and identical mechanical packaging (8-SMD Module, 5 Leads), ensuring direct PCB footprint compatibility.

Regulatory Classification: Both parts carry identical ECCN (EAR99) and HTSUS (8504.40.9580) classifications, with REACH Unaffected status.

Selection of the R1S-2412/P eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the R1S-2412/P be used as a direct replacement for the RSS-2412/P on existing PCBs?

A: Yes. Both components share identical package types (8-SMD Module, 5 Leads), mounting methods (Surface Mount), and physical lead configurations. The R1S-2412/P is a direct PCB footprint replacement.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Input voltage range (21.6V to 26.4V), output voltage (12V), maximum output current (84mA), power rating (1W), isolation voltage (1 kV), and efficiency (80%) are identical. The R1S-2412/P extends the maximum operating temperature to 100°C versus 85°C for the RSS-2412/P.

Q: Why is the RSS-2412/P classified as Obsolete?

A: The RSS-2412/P is part of the ECONOLINE RSS (1W) series, which has been superseded by the ECONOLINE R1S (1W) series. The R1S-2412/P represents the current active product line from Recom Power.

Q: What is the significance of the extended temperature range in the R1S-2412/P?

A: The R1S-2412/P operates to 100°C maximum versus 85°C for the RSS-2412/P. This extended range provides additional thermal margin for applications in elevated ambient temperature environments or systems with higher internal heat dissipation.

Q: Are both parts RoHS compliant?

A: Yes. Both the RSS-2412/P and R1S-2412/P are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.
