PMJ5918TP Equivalent & Substitute DC-DC Converter Reference

Part Overview

The Flex Power Modules PMJ5918TP is a non-isolated point-of-load (PoL) DC-DC converter designed for ITE (commercial) applications. It delivers 0.8 to 3.3V at up to 30A output from a 4.5V to 5.5V input. The product is currently designated as Obsolete, making it necessary to identify suitable equivalent or substitute models strictly based on electrical, mechanical, and regulatory parameters to facilitate continued design support and field replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitutes for the PMJ5918TP are identified strictly by matching or exceeding key operational, regulatory, and mechanical parameters. These include module type (non-isolated PoL), number of outputs, output voltage and current ranges, input voltage range, power rating, efficiency, mounting method, package/case style, operating temperature range, application suitability, supported features, safety approvals, RoHS and REACH compliance, and standard conformity. Only devices with equal or broader compliance in these parameters are included as valid substitutions.

Parameter Comparison

Engineering Selection Recommendations

The PMJ5918TP has an Obsolete product status. Valid substitutes, such as BMR4640002/001, must match or exceed the original part’s safety certifications (CB, CSA, IEC, TUV, UL) and compliance (ROHS3, REACH Unaffected). Compatible substitutes must also adhere to the same standard number (62368-1) and application suitability for ITE (Commercial). Product status and regulatory compliance are mandatory for selection.

Frequently Asked Questions (FAQ)

Q1: What key parameters are used for substituting PMJ5918TP?
A1: Substitution is based on module type, number of outputs, output voltage range, output current, input voltage range, power rating, efficiency, mounting type, package/case, size, operating temperature, supported features, safety approvals, RoHS and REACH compliance, and application suitability.

Q2: Can BMR4640002/001 be used as a substitute for PMJ5918TP?
A2: BMR4640002/001 aligns with the required operational, mechanical, and regulatory parameters including supported voltage range, output current, ITE application suitability, and necessary compliance and approvals.

Q3: Are there any differences in packaging between the PMJ5918TP and its substitute?
A3: There is a difference in package/case type (13-DIP vs. 20-DIP module) and physical dimensions. Review footprint compatibility as required for mechanical fit.

Q4: Does the substitute offer additional features compared to the PMJ5918TP?
A4: BMR4640002/001 includes PMBus™ digital interface in addition to the features supported by the PMJ5918TP. All other primary features are present.

Q5: What regulatory compliance aspects must be checked for substitution?
A5: Substitute components must meet the same safety approvals (CB, CSA, IEC, TUV, UL), RoHS3 status, REACH unaffected status, and standard number 62368-1 as the original part.
