BRFS50L-R Equivalent & Substitute Parts Reference

Part Overview

The Cosel USA, Inc. BRFS50L-R is a Non-Isolated PoL Module DC-DC Converter delivering a single output voltage adjustable from 0.7V to 2V, with up to 50A maximum output current and a 4.5V – 14V input range. It features remote on/off, overcurrent protection (OCP), and supports ITE (Commercial) applications. The BRFS50L-R is now obsolete, making it necessary to identify alternative models for continued product support and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching the following key parameters: type (Non-Isolated PoL Module), number of outputs, input voltage range (4.5V – 14V), adjustable output voltage range (0.7V ~ 2V), minimum output current capability (50A or higher), identical features (Remote On/Off, OCP), identical efficiency (88%), mounting type (Surface Mount), and compatible package dimensions. Substitute parts must carry identical compliance characteristics (ROHS3, CE, cURus, TUV) and the same MSL rating, ensuring fit and regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

The BRFS50L-R is obsolete, while the BRFS60-R is active and in stock. Both models are ROHS3 Compliant, carry CE, cURus, and TUV approvals, and share identical Moisture Sensitivity Level ratings. These compliance and certification alignments ensure regulatory acceptance and compatibility when selecting the BRFS60-R as a replacement for the BRFS50L-R.

Frequently Asked Questions (FAQ)

Q1: What criteria determine if BRFS60-R can substitute BRFS50L-R?
A1: The substitution is determined strictly by matching electrical parameters (input/output voltage ranges, current rating, type, features), mechanical compatibility (mounting type, package/case, dimensions), and identical compliance certifications.

Q2: Does the higher maximum output current of BRFS60-R affect compatibility?
A2: Both modules support 0.7V – 2V output and at least 50A output; the additional current capability in BRFS60-R does not restrict substitutability within provided parameters.

Q3: Are the mounting and package types interchangeable for BRFS50L-R and BRFS60-R?
A3: Both parts use a 14-SMD Module package and surface mount, with size/dimension variations within the allowed category tolerances.

Q4: Are all compliance and approval certifications identical?
A4: Both BRFS50L-R and BRFS60-R are approved by CE, cURus, and TUV, and are ROHS3 Compliant.

Q5: Does the Moisture Sensitivity Level differ between the parts?
A5: Both BRFS50L-R and BRFS60-R specify MSL 2 (1 Year), ensuring equivalent storage and handling requirements.
