Equivalent & Substitute Parts for PDM2-S24-D3-S

Part Overview

The CUI Inc. PDM2-S24-D3-S is an isolated DC-DC converter module designed for ITE (Commercial) applications, with dual outputs of +3.3V and -3.3V at 200mA each and a total power output of 2W. The module offers 1.5kV isolation, SCP (Short Circuit Protection), and through-hole mounting in a 6-SIP package. As the PDM2-S24-D3-S has been designated Obsolete, finding suitable replacements is essential for ongoing maintenance, repair, and production continuity where this module has been used.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on matching or exceeding the key electrical and mechanical parameters of the PDM2-S24-D3-S. These parameters include input voltage range, number of outputs, output voltage(s), maximum output current, output power, isolation voltage, package, mounting type, RoHS compliance, and operating temperature range. Only parts that meet all specified minimum requirements are considered as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The PDM2-S24-D3-S is obsolete, while the PDME2-S24-D3-S is active and available. Both parts are RoHS compliant and REACH unaffected, with matching electrical characteristics and package types. The substitute part also provides certifications (CE, cURus) according to the supplied information.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting PDM2-S24-D3-S with an equivalent part?
A1: Critical parameters include matching input voltage range (21.6V to 26.4V), number of outputs (2), output voltages (+3.3V, -3.3V), output currents, isolation voltage (1.5 kV), mounting type (through hole), package (6-SIP Module, 5 Leads), and compliance status.

Q2: Are there any compatibility concerns with footprint or dimensional differences?
A2: Both PDM2-S24-D3-S and the substitute PDME2-S24-D3-S use the 6-SIP Module, 5 Leads package type with nearly identical dimensions, supporting direct mechanical replacement.

Q3: Does the substitute part meet compliance requirements?
A3: Both parts are RoHS compliant and REACH unaffected. The substitute PDME2-S24-D3-S also lists CE and cURus certifications.

Q4: Can the output current differ between main and substitute parts?
A4: The substitute (PDME2-S24-D3-S) supports higher maximum output current (300mA vs. 200mA) while providing specified output voltages within the same input range.

Q5: Is there any change in efficiency between the parts?
A5: The PDM2-S24-D3-S has a listed efficiency of 80%, while the substitute PDME2-S24-D3-S specifies 76%. This is strictly per provided data. Efficiency must be considered for system thermal requirements within the specified application.
