Frequently Asked Questions (FAQ)

Q: Can the R1S-3.315/H be used as a direct replacement for the RSS-3.315/H in existing designs?

A: Yes. The R1S-3.315/H provides complete electrical and mechanical equivalence to the RSS-3.315/H. All critical parameters including input/output voltage specifications, current ratings, isolation voltage, package type, and compliance certifications are identical. The component can be substituted without circuit modification or PCB redesign.

Q: What is the primary difference between the RSS-3.315/H and R1S-3.315/H?

A: The primary differences are product status and operating temperature range. The RSS-3.315/H is obsolete with a maximum operating temperature of 85°C, while the R1S-3.315/H is an active product with an extended maximum operating temperature of 100°C. All electrical specifications and package configurations remain identical.

Q: Are there any package or footprint differences between these parts?

A: No. Both the RSS-3.315/H and R1S-3.315/H use identical 8-SMD Module, 5 Leads packaging with the same surface mount configuration. PCB layouts and assembly processes require no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RSS-3.315/H and R1S-3.315/H are ROHS3 compliant and REACH unaffected. They are suitable for identical applications in ITE (Commercial) and Medical environments without additional compliance qualification.

Q: What is the significance of the extended operating temperature range in the R1S-3.315/H?

A: The R1S-3.315/H extends the maximum operating temperature from 85°C to 100°C. This provides additional thermal margin for applications exposed to elevated ambient conditions or high-density thermal environments, while maintaining all other electrical performance characteristics.

Q: Is the R1S-3.315/H available in the same packaging options as the RSS-3.315/H?

A: The R1S-3.315/H is supplied in Tube packaging, while the RSS-3.315/H was supplied in standard packaging. Both use identical component-level package types (8-SMD Module, 5 Leads). Packaging format does not affect electrical performance or PCB compatibility.

Q: Can the R1S-3.315/H handle the same input voltage range as the RSS-3.315/H?

A: Yes. Both parts accept identical input voltage specifications of 3V to 3.6V and deliver identical 15V output at 66mA maximum current. Input voltage tolerance and regulation characteristics are equivalent.

Q: Are there any thermal or efficiency differences between these parts?

A: No. Both parts maintain 82% efficiency and identical thermal characteristics under rated load conditions. The extended operating temperature range of the R1S-3.315/H refers to the maximum ambient temperature the component can withstand, not a change in thermal performance.
