Substitute Part Grouping Explanation
The substitute part R1S-0505 is selected strictly on the basis of equivalent electrical, mechanical, and compliance parameters. The substitution logic is limited to:
- Identical input voltage range (4.5V – 5.5V)
- Identical output voltage and current (5V, 200mA)
- Equal power rating (1W)
- Same isolation voltage (1kV)
- Equivalent mounting type and package
- Matching RoHS and REACH compliance
- Commercial ITE application support
- Compatible size and dimensions These core parameters ensure direct interchangeability within the DC-DC converter product category.

Engineering Selection Recommendations
The RSS-0505 is obsolete. The substitute R1S-0505 matches all required electrical, mechanical, and compliance parameters, including RoHS3 and REACH status, ECCN classification, and Moisture Sensitivity Level. R1S-0505 is in active production with verified inventory, suitable for direct replacement in ITE (Commercial) applications.
Frequently Asked Questions (FAQ)
Q: What electrical parameters must match for a DC-DC converter substitution?
A: Voltage input range, output voltage, output current, output power, and isolation voltage must be identical.
Q: Is the package type and mounting method the same between RSS-0505 and R1S-0505?
A: Both models use an 8-SMD Module, 5 Leads package and are surface-mount compatible, with close dimensional specifications.
Q: Are both parts compliant with RoHS and REACH regulations?
A: Yes. Both RSS-0505 and R1S-0505 are ROHS3 Compliant and REACH Unaffected.
Q: Does the substitute part offer a broader operating temperature range?
A: R1S-0505 supports operating temperatures from -40°C to 100°C.
Q: Should I consider moisture sensitivity for inventory and assembly?
A: Both RSS-0505 and R1S-0505 have an MSL level of 1, indicating unlimited shelf life and ease of assembly.
Q: Are there any differences in physical size affecting PCB design?
A: RSS-0505 measures 0.50" x 0.32" x 0.29" (12.8mm x 8.2mm x 7.3mm) and R1S-0505 measures 0.50" x 0.42" x 0.28" (12.8mm x 10.7mm x 7.0mm). Consider physical width during layout validation.
