Equivalent & Substitute Parts for PDM2-S5-D5-D

Part Overview

The CUI Inc. PDM2-S5-D5-D is a 2W isolated DC-DC converter module with dual outputs (+5V, -5V at 200mA each), 1.5kV isolation, through-hole mounting, and a 14-DIP 6-lead package. It supports a 4.5V to 5.5V input range and is approved to CB Scheme, EN, IEC, and UL standards. This model is classified as obsolete, making it necessary to identify equivalent and substitute parts to maintain supply continuity and ensure design compatibility.

Engineering Selection Recommendations

Selection is based on product status, compliance, and approvals. The PDM2-S5-D5-D is obsolete. Substitute parts PDME2-S5-D5-D and PDME2-S5-D5-S are active and meet relevant RoHS and REACH requirements. Substitute models have cURus approval and correspond to IEC 62368-1. Moisure Sensitivity Level (MSL) and environmental regulatory status match the original part where data is provided.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting the PDM2-S5-D5-D?
A: Key substitution parameters include input voltage range (4.5V–5.5V), output voltages (+5V, -5V), output current (200mA), output power (2W), isolation voltage (1.5 kV), number of outputs (2), module type (Isolated), mounting type (Through Hole), and package/case compatibility.

Q2: Are the package dimensions and lead configurations identical among substitutes?
A: The original uses a 14-DIP 6-lead package (0.80" x 0.40" x 0.32"). Substitute parts use a 7-SIP 5-lead package (0.77" x 0.28" x 0.40"). Mechanical footprint differs; review dimensional compatibility within your application.

Q3: Do substitute models have the same regulatory and environmental compliance as the original?
A: Substitute parts are RoHS and REACH compliant, with cURus and IEC 62368-1 approvals, matching or exceeding the environmental status of the original part.

Q4: Does operating temperature differ among the listed substitute parts?
A: All parts in this group have an operating temperature range of -40°C to 105°C with derating.

Q5: What mounting type should be considered when selecting an equivalent or substitute DC-DC converter?
A: All listed parts are through-hole mounted. Ensure mechanical and PCB layout compatibility with the alternate package.
