Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined strictly by comparing the following parameters: input voltage range, output voltage, maximum output current, isolation voltage, power rating, operating temperature, efficiency, mounting type, package/case dimensions, and compliance (RoHS, REACH, ECCN, HTSUS), as well as application and feature compatibility. All substitute models in the group maintain equivalent or identical values for these listed parameters.

Parameter Comparison

Engineering Selection Recommendations

Selection of an alternative part in this scenario is determined by the obsolete status of RSS-123.3/P and the need for continued compliance with RoHS3 and REACH directives. Substitute part R1S-123.3/P is active and maintains equivalent electrical, mechanical, and compliance parameters. All certifications and regulatory statuses as listed are identical. Only base official inventory data and provided features should be used to select the correct part.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting RSS-123.3/P with another component?
A1: Substitution must be based on input voltage range, output voltage and current, power rating, isolation voltage, temperature rating, mounting type, package/case, compliance status (RoHS, REACH), application, and features.

Q2: Is the package/case the same for RSS-123.3/P and R1S-123.3/P?
A2: Both parts use an 8-SMD Module, 5 Leads form factor. R1S-123.3/P has a width of 10.7mm versus 8.2mm for RSS-123.3/P; other dimensions are comparable.

Q3: Does the substitute operate in the same temperature range?
A3: R1S-123.3/P listed operating temperature is -40°C ~ 100°C, which includes and exceeds the -40°C ~ 85°C range of RSS-123.3/P.

Q4: Are RoHS and REACH compliance identical for both parts?
A4: Both RSS-123.3/P and R1S-123.3/P are ROHS3 compliant and REACH unaffected.

Q5: Is the substitute part suitable for ITE (Commercial) applications?
A5: Yes, both components are specified for ITE (Commercial) usage.

Q6: What changes in inventory status should be considered?
A6: RSS-123.3/P is obsolete, while R1S-123.3/P is active and available in stock per provided inventory data.
