Equivalent & Substitute Parts for SFS13ZE-M6G

Part Overview

The SFS13ZE-M6G from Bel Power Solutions is an isolated DC DC converter module, providing a single 3.3V output at up to 13A (43W) from a 36V–72V input. With features such as remote on/off and OCP, it is designed for ITE (Commercial) applications. This module is currently listed as Obsolete, making it necessary to identify suitable alternative models to maintain compatibility in both current designs and legacy support.

Key Parameters

Substitute Part Grouping Explanation

Identification of substitute DC DC converters is based strictly on the following parameters: input voltage range, output voltage and current, output power, voltage isolation, number of outputs, mounting type, package, compliance (RoHS, REACH), intended application, and control features. Only substitute parts matching or exceeding the requirements in these categories are considered functionally compatible.

Parameter Comparison

Engineering Selection Recommendations

The SFS13ZE-M6G is classified as Obsolete, while the substitute part UWS-3.3/15-Q48PM-C maintains an Active status. Both modules are ROHS3 Compliant and REACH Unaffected, meeting current regulatory compliance requirements. The Murata UWS-3.3/15-Q48PM-C provides a higher output current and power, maintains isolated output, and includes comparable control features. Moisture Sensitivity Levels differ, and the dimensions and package style should be considered for board compatibility.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match to substitute a DC DC converter module like SFS13ZE-M6G?
A1: The substitution relies on matching or exceeding input voltage range, output voltage and current, power rating, isolation voltage, number of outputs, intended application, mounting type, package/case, control features, and regulatory compliance.

Q2: Is the output power and current of the substitute part compatible?
A2: UWS-3.3/15-Q48PM-C provides a higher maximum output current and power rating compared to SFS13ZE-M6G, meeting or exceeding the primary output requirements.

Q3: Are there differences in package or mounting type?
A3: Both modules use surface mount technology, but the package/case footprint and dimensions are different. Review mechanical constraints to ensure form factor compatibility.

Q4: What compliance considerations are relevant?
A4: Both parts are ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Levels differ; SFS13ZE-M6G is MSL 1 (Unlimited), while UWS-3.3/15-Q48PM-C is MSL 2 (1 Year).

Q5: Is there any difference in control or feature set between these modules?
A5: Both modules support Enable and Active High control features. Functional attributes such as Remote On/Off are present, with a difference in the specific protection or monitoring features listed (OCP vs UVLO).
