Engineering Selection Recommendations

Due to the obsolete status of RSS-2409/HP and continued ROHS3 and REACH compliance requirements, R1S-2409/HP is a suitable alternative. Both models retain identical electrical performance and compliance criteria. The substitute part is active and meets provided safety and environmental standards.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for substituting RSS-2409/HP with R1S-2409/HP?
A1: Substitution is based on identical input voltage, output voltage, output current, power, isolation voltage, mounting type, package, and compliance status.

Q2: Does the difference in product status affect usage?
A2: RSS-2409/HP is obsolete, while R1S-2409/HP is active, ensuring continuity in supply and support.

Q3: Are there differences in size/dimension that might affect the design?
A3: R1S-2409/HP has a slightly different width and height; review mechanical compatibility in existing layouts.

Q4: Is package and pin configuration the same for both parts?
A4: Both parts use an 8-SMD Module, 5 Leads package, maintaining consistent footprint and mounting approach.

Q5: What compliance or certification parameters are matched in this substitution?
A5: Both models are ROHS3 Compliant, REACH Unaffected, and have Moisture Sensitivity Level 1, ensuring environmental and handling equivalence.
