Equivalent & Substitute Parts Reference for PDM2-S5-D7-D

Part Overview

PDM2-S5-D7-D, manufactured by CUI Inc., is an isolated module DC-DC converter featuring two outputs of +7V and -7V at 142mA each, with 2W total output power. The device supports a 4.5V–5.5V input range, provides 1.5kV isolation, and is suitable for ITE (commercial) applications. Its mounting is through-hole in a 14-DIP module (6 leads) package. The part is now marked as Obsolete, necessitating the identification of substitute models with equivalent or compatible parameters for ongoing or new designs.

Engineering Selection Recommendations

PDM2-S5-D7-D is classified as Obsolete. PDME2-S5-D7-D, by the same manufacturer, is Active and matches key electrical, mechanical, and compliance parameters. Both parts are RoHS compliant, and PDME2-S5-D7-D holds additional cURus approval and conform to 62368-1 standards. Differences are limited to package style and output current (143mA vs. 142mA), with otherwise equivalent performance by listed parameters.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters must match when substituting PDM2-S5-D7-D?
A1: Substitute selection requires matching type (Isolated Module), number of outputs (2), output voltages (+7V, -7V), output current, input voltage range (4.5V–5.5V), total output power (2W), and isolation voltage (1.5kV).

Q2: Is the mounting type and package a critical substitution consideration?
A2: Yes. PDM2-S5-D7-D uses a 14-DIP Module with 6 leads, while PDME2-S5-D7-D uses a 7-SIP Module with 5 leads. Mechanical compatibility must be confirmed based on footprint and pinout requirements.

Q3: Are there environmental or compliance differences between the standard and substitute part?
A3: Both parts are RoHS Compliant. PDME2-S5-D7-D also indicates cURus recognition and standard 62368-1 compliance. REACH status for PDME2-S5-D7-D is not specified in the input.

Q4: Can the minor output current difference affect substitution?
A4: The substitute part (PDME2-S5-D7-D) lists output currents of 143mA per channel versus 142mA for the PDM2-S5-D7-D. This is within the category range according to provided data.

Q5: Are there approved usage standards for the substitute part?
A5: The substitute PDME2-S5-D7-D has cURus approval and conforms to standard number 62368-1. PDM2-S5-D7-D does not specify these certifications in the input parameters.
