Flex Power Modules PME5118VPF Equivalent & Substitute Parts Reference

Part Overview

The Flex Power Modules PME5118VPF is a non-isolated Point of Load (PoL) DC-DC converter rated for up to 6A output current, with an output voltage range of 0.55–1.8V, and an input voltage range of 4.5–5.5V. It is designed for ITE (Commercial) applications and provides features such as adjustable output and remote on/off control. As the product status is "Obsolete," sourcing this module for new designs or ongoing maintenance requires identification of alternative models with matching electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The PME5118VPF is listed as obsolete, requiring a substitute for new or ongoing designs. Texas Instruments PTH05050YAH is active and matches all mandatory compliance specifications, including RoHS3, REACH status, ECCN, HTSUS, operating temperature range, and certified standards. Both options utilize a 6-DIP through-hole package, supporting direct mechanical replacement based strictly on provided parameters.

Frequently Asked Questions (FAQ)

Q1: What key criteria are required for substituting PME5118VPF?
A1: Substitute models must match type, input and output voltage ranges, output current rating, operating temperature, mounting type, package dimensions, and compliance certifications.

Q2: Is the PTH05050YAH directly compatible in mechanical mounting with PME5118VPF?
A2: Both use the 6-DIP through-hole module package. Provided dimensions differ by 0.01" in width, which falls within standard PCB layout tolerances for this category.

Q3: Do both modules meet current regulatory and environmental standards?
A3: Both are ROHS3 compliant and REACH unaffected, addressing key environmental regulatory standards.

Q4: How does the efficiency rating compare between the two parts?
A4: PME5118VPF specifies 87.2% efficiency, PTH05050YAH lists 87%. The difference is minimal within documented performance specifications.

Q5: Are there differences in control and protection features between the parts?
A5: Control and protection features specified include remote on/off or enable. Other features, if required, must be verified per supplied documentation.

Q6: Is there any difference in the operating temperature range?
A6: Both are specified for -40°C to +85°C operation, ensuring full compatibility with standard ITE (Commercial) requirements.
