Equivalent & Substitute Parts Reference for PDM2-S3-S5-D

Part Overview

PDM2-S3-S5-D is an obsolete isolated DC-DC converter module manufactured by CUI Inc. The module delivers 2W output at 5V with 400mA max output current and supports an input voltage range of 2.97V to 3.63V. It features a 1.5 kV isolation and is designed for commercial ITE applications, with through hole mounting in a 14-DIP module case. Due to its obsolete product status, it is necessary to identify alternative models with matching electrical and mechanical parameters for compatible substitution.

• Operating temperature range: -40°C ~ 105°C

Substitution is based only on parameters explicitly provided for compatibility; package and compliance features are considered for mechanical and regulatory fit.

Parameter Comparison

Engineering Selection Recommendations

The PDM2-S3-S5-D is obsolete, while PDME2-S3-S5-D is active. Both parts have identical core electrical specifications and are RoHS compliant. PDME2-S3-S5-D also carries cURus approval and standard number 62368-1, aligning with regulatory requirements for ITE (Commercial) applications. The mounting type and number of outputs are matched. The package differs, requiring assessment for mechanical fit based solely on provided form factor; electrical and application compatibility is maintained.

Frequently Asked Questions (FAQ)

Q1: What are the critical substitution criteria for PDM2-S3-S5-D?
A1: Substitution is determined strictly by matching output voltage (5V), output current (400mA), input voltage range (2.97V–3.63V), isolation voltage (1.5 kV), power (2W), module type (Isolated), application category (ITE Commercial), mounting type (Through Hole), operating temperature range (-40°C ~ 105°C), and package dimensions.

Q2: Is mechanical compatibility guaranteed between 14-DIP and 7-SIP modules?
A2: Package/case dimensions and pin configuration must be verified for board-level compatibility. Electrical characteristics are matched, but mechanical fit depends on the provided dimensions and package style: 14-DIP Module, 6 Leads vs. 7-SIP Module, 4 Leads.

Q3: Are both PDM2-S3-S5-D and PDME2-S3-S5-D compliant with RoHS and applicable regulations?
A3: Both models are listed as RoHS compliant, and PDME2-S3-S5-D includes cURus and standard 62368-1 approval, supporting usage in ITE (Commercial) environments.

Q4: How do operating temperature ranges compare?
A4: Both converters are specified for -40°C ~ 105°C operation; PDME2-S3-S5-D notes operation with derating across this range.

Q5: What should be considered regarding inventory availability?
A5: PDM2-S3-S5-D is obsolete but available in limited stock. PDME2-S3-S5-D is active and available for ongoing design requirements.
