Equivalent & Substitute Parts Reference for PMH8918LP

Part Overview

The PMH8918LP, manufactured by Flex Power Modules, is a non-isolated Point of Load (PoL) DC-DC converter module intended for ITE (Commercial) applications. It features a single adjustable output of 0.8~1.8V at 18A, with an input voltage range of 10.8V to 13.2V and a maximum output power of 32 W. The device is available in a through-hole 10-DIP module package. Its product status is listed as obsolete, which necessitates the identification and evaluation of direct substitute or equivalent models to ensure continued availability and design compatibility for maintenance or new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute suitability is determined strictly by matching electrical, mechanical, and regulatory parameters relevant to non-isolated PoL DC-DC converters. These parameters include input voltage range, output current rating, power capability, output configuration (single output), mounting type, package size and footprint, application, environmental compliance, and operating temperature range. All substitute parts listed match or exceed these critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The PMH8918LP is obsolete, necessitating the use of substitute parts for ongoing or new designs. Substitute selection is confined to parts that are active, RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTS code 8504.40.9580. PTH12020WAH fulfills these regulatory and compliance criteria.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria to determine equivalence for a non-isolated PoL DC-DC converter?
A1: Key criteria include input voltage range, output current capability, mounting type, package footprint, application compatibility, and regulatory compliance.

Q2: Is mounting compatibility ensured between PMH8918LP and PTH12020WAH?
A2: Both parts use a through-hole 10-DIP module package, with closely matched physical dimensions.

Q3: Do substitute parts support the same output current rating as the PMH8918LP?
A3: The PTH12020WAH provides an identical maximum output current of 18A.

Q4: Are the environmental and regulatory compliances aligned?
A4: Both parts are RoHS3 compliant, REACH unaffected, classified as EAR99, and share the same HTSUS code.

Q5: Do the substitute models provide a suitable operating temperature range?
A5: Both the PMH8918LP and PTH12020WAH specify an operating temperature range of -40°C to 85°C.

Q6: Are there differences in output voltage adjustment?
A6: The PMH8918LP supports 0.8~1.8V output; PTH12020WAH covers a range of 1.2~5.5V. Ensure output needs are within the range provided by the substitute part.
