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

Part Overview

The CUI Inc. PDM2-S5-S5-D is an isolated DC DC converter providing a single 5V output at up to 400mA from a 4.5V – 5.5V input, rated for 2W maximum output power with 1.5 kV isolation. This product is classified as obsolete. When a DC DC converter with identical electrical and mechanical specifications is required and the original part is no longer available, substitution with an approved equivalent is necessary to maintain compatibility and compliance in ITE (Commercial) applications.

Engineering Selection Recommendations

Substitute selection for the obsolete PDM2-S5-S5-D should be based on the availability of active products with matching electrical ratings, regulatory compliance, and agency approvals as provided. PDME2-S5-S5-D and PDME2-S5-S5-S are active CUI Inc. DC DC converters offering equivalent input range, output voltage and current, isolation rating, mounting type, and certifications per ITE (Commercial) application requirements. RoHS and REACH compliance, as well as regulatory approvals, are indicated per supplied documentation.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters must match when choosing a substitute for PDM2-S5-S5-D?
A1: Input voltage range (4.5V – 5.5V), single output voltage (5V), output current (400mA), output power (2W), and isolation voltage (1.5kV) must match exactly.

Q2: Are the substitute models compatible with the same application category?
A2: All listed substitutes are classified under ITE (Commercial) applications per manufacturer documentation.

Q3: Are there any compliance or regulatory differences between the original and substitute parts?
A3: Substitute parts provide RoHS and REACH compliance, with alternate agency approvals (cURus vs. CB Scheme, EN, IEC, UL) and standard numbers, as specified in the parameter comparison.

Q4: Do replacement parts use the same mounting method?
A4: Substitutes use through-hole mounting. Package type varies between 14-DIP Module, 6 Leads and 7-SIP Module, 4 Leads. Review mechanical fit based exclusively on provided dimensions.

Q5: Does efficiency vary between the original and substitutes?
A5: The original part (PDM2-S5-S5-D) has an efficiency of 85%. Substitute parts (PDME2-S5-S5-D and PDME2-S5-S5-S) specify 84% efficiency.

Q6: Are environmental and moisture sensitivity ratings maintained in substitutes?
A6: All parts specify Moisture Sensitivity Level (MSL) 1 (Unlimited) and REACH Unaffected status.
