Equivalent & Substitute Parts Reference for BRFS50

Part Overview

The Cosel USA, Inc. BRFS50 is a Non-Isolated PoL Module DC-DC converter, designed for ITE (Commercial) applications. It provides a highly regulated output voltage of 0.7 V to 2 V at up to 50 A from a 4.5 V to 14 V input range. The BRFS50 has a product status of Obsolete, increasing the need to identify equivalent and substitute parts for ongoing designs and maintenance. Substitution is necessary to ensure supply continuity and regulatory compliance when the original part is no longer available.

Parameter Comparison

Engineering Selection Recommendations

Selection of the BRFS60 as a substitute for BRFS50 is based strictly on matching electrical and mechanical parameters, as well as identical approval agencies and RoHS/REACH compliance status. BRFS60 is an active product and meets all mandatory certification and compliance requirements identified for the original BRFS50.

Frequently Asked Questions (FAQ)

Q1: What are the key parameters when selecting a substitute for BRFS50?
A1: The key parameters are Series, Type, Number of Outputs, Input Voltage Range, Output Voltage Range, Maximum Output Current, Applications, Features, Operating Temperature Range, Efficiency, Mounting Type, Package / Case, Size / Dimension, Approval Agency, RoHS Status, and Moisture Sensitivity Level.

Q2: Does BRFS60 have the same mounting and package as BRFS50?
A2: Yes. Both BRFS50 and BRFS60 are Surface Mount modules in a 14-SMD Module package, with matching length and width. The height differs slightly (BRFS60: 8.0mm; BRFS50: 9.5mm).

Q3: Are the electrical characteristics compatible between the BRFS50 and BRFS60?
A3: Yes. Both have identical input voltage ranges (4.5V to 14V), output voltage ranges (0.7V to 2V), and feature sets. The BRFS60 supports a higher maximum output current (60A vs. 50A).

Q4: Are both parts compliant with RoHS and covered by the same safety agencies?
A4: Yes. Both BRFS50 and BRFS60 are covered by CE, cURus, and TUV approvals and are ROHS3 compliant.

Q5: What is the impact of the status difference between BRFS50 and BRFS60?
A5: BRFS50 is Obsolete, making BRFS60, which is Active, the eligible substitute with matched compliance and approved certifications.
