Equivalent & Substitute Parts for PMH8918LSR

Part Overview

The Flex Power Modules PMH8918LSR is a Non-Isolated Point-of-Load (PoL) DC-DC Converter with adjustable output, designed for ITE (Commercial) applications. This product offers a single output of 0.8–1.8V (up to 18A) from a 10.8V–13.2V input, supporting a maximum power output of 32W. It is supplied in a surface-mount 10-SMD module package. PMH8918LSR is currently classified as Obsolete, necessitating the identification of substitute parts for ongoing and future designs.

Engineering Selection Recommendations

PMH8918LSR is designated as Obsolete, making it necessary to select an active substitute to maintain continuity in designs. Substitute part PTH12020WAZ is an active product, matching all mandatory compliance requirements such as ROHS3, REACH, and MSL 3 (168 Hours). Both parts are comparable in operating temperature and package, and both are suited to ITE (Commercial) applications.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for substituting PMH8918LSR with another part?
A1: The substitute must match type (Non-Isolated PoL Module), number of outputs, input voltage range, output current, package (10-SMD Module), surface mount compatibility, similar size/dimensions, required operating temperature range, and compliance statuses (RoHS, REACH, MSL).

Q2: Are there differences in package and mounting between PMH8918LSR and PTH12020WAZ?
A2: Both parts use a 10-SMD Module package and surface mount configuration. The physical dimensions are similar, with minor differences in height.

Q3: Will compliance requirements be affected by the substitute?
A3: Both PMH8918LSR and PTH12020WAZ are ROHS3 Compliant, REACH Unaffected, and classified as MSL 3 (168 Hours).

Q4: Is the substitute compatible in terms of input and output voltages?
A4: Both support the same input voltage range (10.8V–13.2V). Output voltage ranges differ; verify the desired setpoint falls within the available range for each module.

Q5: What is the product status difference between main and substitute parts?
A5: PMH8918LSR is Obsolete, while PTH12020WAZ is Active.
