|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| SFS10481R5A | SFS (10W) | Obsolete | Isolated Module | 1 | 36V | 76V | 1.5V | 3.5A | 5.25 W | 1.5 kV | -40°C ~ 85°C (With Derating) | 82% | 1.52" L x 1.07" W x 0.20" H | ROHS3 Compliant | ITE (Commercial) |
Substitute Part Grouping Explanation
Substitution is determined by matching the following key electrical and mechanical parameters: input voltage range (36V ~ 76V), output voltage (1.5V), maximum output current, power rating, voltage isolation (1.5 kV), operating temperature range (-40°C ~ 85°C with derating), efficiency (82%), number of outputs (1), RoHS compliance, and intended application (ITE commercial). Only parts meeting these criteria are included as substitutes.

Engineering Selection Recommendations
Based on the provided information, the SFS10481R5A is discontinued. The SFLS15481R5B is an active alternative from the same manufacturer and shares all primary certification and compliance attributes, specifically ROHS3 compliance and application scope (ITE commercial). Both parts are listed with EAR99 ECCN and comply with HTSUS 8504.40.9580. Selection is permissible within the provided categories and certifications.
Frequently Asked Questions (FAQ)
Q: What are the critical substitution criteria for the SFS10481R5A DC-DC converter?
A: Substitute models must match input voltage range, output voltage, voltage isolation, operating temperature, efficiency, and compliance requirements. The SFLS15481R5B meets all these parameters.
Q: Is there any difference in mounting or package that affects compatibility?
A: The SFLS15481R5B uses a surface mount configuration (18-SMD module, 15 leads) and has different physical dimensions compared to the SFS10481R5A. Verify physical and mounting compatibility at the system level.
Q: Do substitute parts provide the same output characteristics?
A: The substitute SFLS15481R5B provides the same output voltage (1.5V) and supports a higher maximum output current (5.2A) and power (7.8W). Electrical parameters are compatible within the provided data.
Q: Is RoHS compliance maintained when substituting with SFLS15481R5B?
A: Both SFS10481R5A and SFLS15481R5B are ROHS3 compliant.
Q: Are there differences in application suitability?
A: Both parts are specified for ITE (commercial) applications according to provided parameters.
Q: Does operating temperature differ between the substitute and original part?
A: Both parts operate within -40°C ~ 85°C (with derating), ensuring compatibility in rated environments.
Q: Are there inventory considerations?
A: SFLS15481R5B is listed as active and available in stock, while SFS10481R5A is obsolete.
