Equivalent & Substitute Parts Reference Page for PDM2-S5-S5-S

Part Overview

The PDM2-S5-S5-S from CUI Inc. is an active, isolated DC-DC converter module. It provides a regulated 5V output at up to 400mA from a 4.5V to 5.5V DC input, with a total output power of 2W. This through-hole SIP module is designed for ITE (Commercial) applications and features 1.5 kV isolation. Finding alternative models is necessary for supply chain redundancy, inventory stability, or when handling end-of-life notifications.

Parameter Comparison

Engineering Selection Recommendations

Component selection between PDM2-S5-S5-S and PDME2-S5-S5-S is governed by active product status, RoHS and REACH compliance, and recognized agency approvals (CB Scheme, EN, IEC, UL for PDM2-S5-S5-S and cURus for PDME2-S5-S5-S). Both parts are listed as active and are RoHS compliant, with unlimited moisture sensitivity levels and unaffected REACH status.

Frequently Asked Questions (FAQ)

Q1: Which electrical parameters must match to ensure substitution is valid between PDM2-S5-S5-S and PDME2-S5-S5-S?
A1: Input voltage range, output voltage, output current, power rating, and isolation voltage must match. Both parts provide 4.5V–5.5V input, 5V/400mA output, 2 W power, and 1.5 kV isolation.

Q2: Are there differences in mechanical or packaging configurations between the two models?
A2: The PDM2-S5-S5-S uses a 6-SIP Module, 4 Leads, while the PDME2-S5-S5-S is specified as a 7-SIP Module, 4 Leads. Dimensional differences are minimal, but confirmation of fit with the intended PCB footprint is required.

Q3: Are there differences in agency approvals or compliance?
A3: PDM2-S5-S5-S lists CB Scheme, EN, IEC, and UL approvals. PDME2-S5-S5-S lists cURus approval. Selection may depend on the target market's required certifications.

Q4: Does efficiency impact substitution?
A4: PDM2-S5-S5-S is rated at 89% efficiency, while PDME2-S5-S5-S is 84%. There is a quantifiable difference in efficiency within the parameters provided.

Q5: Are there differences in operating temperature?
A5: Both parts support an operating range of -40°C ~ 105°C, with PDME2-S5-S5-S specifying performance with derating.

Q6: How should compliance with RoHS and REACH be assessed?
A6: Both parts are marked as RoHS compliant and REACH unaffected according to provided information.

Q7: Do part numbers differ in their inventory availability or product status?
A7: Both PDM2-S5-S5-S and PDME2-S5-S5-S are marked as active, with distinct inventory quantities in stock.
