Engineering Selection Recommendations

RSS-3.312 is classified as Obsolete, requiring the selection of a substitute for ongoing usage. R1S-3.312 is Active, maintaining regulatory compliance with ROHS3 and REACH certifications, and carries identical electrical performance and application categorization. Both modules meet the ECCN and HTSUS classifications and have unlimited MSL ratings. Selection should be based strictly on product status and compliance documentation.

Frequently Asked Questions (FAQ)

Q1: What parameters must match to qualify as a substitute for RSS-3.312?
A1: Substitution requires matching voltage input range (3V–3.6V), output voltage (12V), output current (84mA), power rating (1W), isolation voltage (1kV), number of outputs (1), module type, mounting, and size/dimension parameters.

Q2: Is the R1S-3.312 suitable in terms of package compatibility?
A2: R1S-3.312 uses the same 8-SMD Module, 5 Leads package as RSS-3.312, with closely comparable dimensions.

Q3: Is there a difference in compliance or certifications between RSS-3.312 and R1S-3.312?
A3: Both modules are ROHS3 Compliant and REACH Unaffected, hold the same ECCN and HTSUS classifications, and have the same MSL.

Q4: What is the impact of product status when selecting a substitute?
A4: Only Active product status ensures continued availability for new designs and procurement, making R1S-3.312 the viable substitute for the Obsolete RSS-3.312.

Q5: Are application categories identical between the two models?
A5: Both models are designated for ITE (Commercial) applications with SCP feature.
