Equivalent & Substitute Parts for SFS30481R2B

Part Overview

The SFS30481R2B by Cosel USA, Inc. is an obsolete isolated module DC-DC converter delivering 1 output of 1.2V at up to 10.4A from a DC input range of 36V to 76V. It provides up to 12 W of output power and features 1.5 kV isolation, is surface-mountable, and operates across -40°C to 85°C with derating. As this model is obsolete, it is necessary to identify substitute parts to maintain supply chain continuity for assemblies requiring the same electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution has been determined solely on the following parameters: electrical compatibility (input voltage range, output voltage, output current, output power, isolation voltage), mechanical compatibility (mounting type, package/case, and size/dimensions as provided), compliance standards (RoHS, Moisture Sensitivity Level, ECCN, HTSUS), and application category. Only parts meeting or exceeding the main part's specifications in all listed fields are grouped as substitutes.

The strictly considered key parameters are:

• Voltage - Input (Min), Voltage - Input (Max)
• Voltage - Output 1
• Current - Output (Max)
• Power (Watts)
• Voltage - Isolation
• Applications
• Operating Temperature
• Mounting Type
• Package / Case
• Size / Dimension
• RoHS Status
• MSL
• ECCN
• HTSUS

Parameter Comparison

Engineering Selection Recommendations

The SFS30481R2B is classified as obsolete, while SFLS30481R2B is active and complies with ROHS3, MSL 2 (1 Year), ECCN EAR99, and HTSUS 8504.40.9580 standards. Substitution can be made based on the alignment of compliance and certification parameters as well as product status.

Frequently Asked Questions (FAQ)

Q: What are the key criteria for substituting SFS30481R2B with SFLS30481R2B?
A: Substitution is based on identical input voltage range, output voltage, isolation voltage, number of outputs, mounting type, RoHS status, MSL, and ECCN/HTSUS classification. Output current, output power, and package/case dimensions must also meet or exceed the minimum requirements.

Q: Are the footprints and package dimensions identical between SFS30481R2B and SFLS30481R2B?
A: The mounting type is the same (surface mount), but package/case style and dimensions differ. Verify compatibility with existing PCB designs.

Q: Do both DC-DC converters support the same application environments?
A: Both are specified for ITE (Commercial) applications and share the same operating temperature range as provided.

Q: Is there any difference in compliance or environmental certifications between these parts?
A: Both parts are ROHS3 Compliant and have an MSL of 2 (1 Year), with identical ECCN and HTSUS codes.

Q: What is the difference in electrical performance between the two models?
A: SFLS30481R2B supports a higher maximum output current (12A vs 10.4A) and power (14W vs 12W) at slightly lower efficiency (84% vs 86%), within the same input and output voltage range.
