Equivalent & Substitute Parts for PMD4118OWP

Part Overview

The Flex Power Modules PMD4118OWP is a non-isolated PoL (Point of Load) DC-DC converter designed for ITE (commercial) applications. It supports a single adjustable output voltage (0.9–3.6V), 3A maximum output current, and a 3V–5.5V input voltage range, packaged in a 6-DIP through-hole module. With an 11 W maximum output, this module is classified as Obsolete, making it necessary to identify available alternative models with matching electrical, mechanical, and compliance parameters for form-fit-function replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitute relationships are determined strictly by matching the following parameters: non-isolated PoL module type, 3V–5.5V input voltage range, 0.9–3.6V adjustable output voltage, 3A maximum output current, through-hole 6-DIP module mounting, ITE (commercial) application, number of outputs, and compliance with ROHS3 and REACH. Only parts with equivalent or directly compatible electrical, mechanical, and compliance characteristics are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection is based on product obsolescence status and compliance. The PMD4118OWP is classified as Obsolete, while the substitute part PTH04000WAH is Active. Both parts meet ROHS3 and REACH requirements. Use of recognized approval agencies and standard number 62368-1 is present on the main part; these details are not specified for the substitute part. Only directly listed compliance and inventory parameters are relevant to substitution in this context.

Frequently Asked Questions (FAQ)

Q1: What criteria make PTH04000WAH a valid substitute for PMD4118OWP?
A1: Both parts are non-isolated PoL DC-DC converters with the same input voltage range (3V–5.5V), identical adjustable output voltage range (0.9–3.6V), the same maximum output current (3A), and are presented in through-hole 6-DIP modules. They are compliant with ROHS3 and unaffected by REACH.

Q2: Are there differences in mechanical footprints between the original and substitute parts?
A2: The substitute part PTH04000WAH has a marginally larger size (0.75" x 0.50" x 0.34") compared to PMD4118OWP (0.74" x 0.49" x 0.33"). Both are 6-DIP through-hole modules.

Q3: Is any change in application or electrical performance expected when replacing PMD4118OWP with PTH04000WAH?
A3: The substitute part matches the number of outputs, input, and output voltage ranges, as well as output current, supporting ITE (Commercial) applications. Both are through-hole modules with comparable features within the provided electrical and mechanical parameters.

Q4: What environmental or regulatory statuses should be noted for substitution?
A4: Both the original and substitute part are ROHS3 Compliant and REACH Unaffected, with an MSL designation of Not Applicable.

Q5: Why is substitution necessary?
A5: The main part PMD4118OWP is Obsolete, making substitution necessary for continuity in design, sourcing, and maintenance operations where directly compatible modules are required.
