Equivalent & Substitute Parts Reference for PDM2-S5-D12-D

Part Overview

The CUI Inc. PDM2-S5-D12-D is an isolated module DC-DC converter designed for ITE (commercial) applications, delivering two 12V outputs at a maximum of 83mA per channel, with 2W total output power. It operates from a 4.5V to 5.5V input, features short-circuit protection, and is housed in a 14-DIP module case. This product is currently marked as "Obsolete," necessitating identification of alternatives for ongoing design, replacement, or inventory purposes.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection for DC-DC converters is strictly based on matching input voltage range, output voltage(s), output current, power rating, isolation voltage, number of outputs, mounting type, operating temperature range, and application compliance. Packaging, approvals, and environmental compliance are also considered. Only products meeting these explicit criteria are listed as equivalents or substitutes.

Key substitution parameters:

• Input voltage range
• Output voltage(s) and configuration
• Maximum output current
• Power rating
• Isolation voltage
• Number of outputs
• Mounting and package/case style
• Operating temperature range
• Relevant approvals and certifications
• Environmental compliance

Engineering Selection Recommendations

Substitute selection for the PDM2-S5-D12-D is based directly on product status and explicit compliance information. Both PDME2-S5-D12-D and PDME2-S5-D12-S are designated as active products and maintain key regulatory and environmental standards such as RoHS compliance, MSL 1, and EAR99 classification. Approval agency credentials and certification numbers are provided for each part.

Package style and physical dimension differences must be considered based solely on the provided data. Output configuration differs for substitutes (12V, -12V versus dual 12V); select strictly based on system voltage requirements. Use the environmental and certification details for compliance verification.

Frequently Asked Questions (FAQ)

Q1: What are the critical electrical parameters for substituting PDM2-S5-D12-D?
A1: Allowed substitutes must match input voltage range (4.5V–5.5V), output current (83mA per channel), power (2 W), voltage isolation (1.5 kV), number of outputs (2), mounting type, and application type (ITE-commercial).

Q2: Are there differences in output voltage configuration between the main part and substitutes?
A2: Yes. The PDM2-S5-D12-D provides dual 12V outputs; PDME2-S5-D12-D and PDME2-S5-D12-S provide +12V and -12V outputs.

Q3: How do the substitute packages compare?
A3: The main part is housed in a 14-DIP module (6 leads), while substitutes use a 7-SIP module (5 leads) case. This impacts footprint and pinout considerations.

Q4: Do substitutes maintain environmental and regulatory compliance?
A4: PDME2-S5-D12-S lists ROHS3 and REACH Unaffected; MSL, ECCN, and HTSUS match the main part. Verify all required certifications per provided data.

Q5: Is the efficiency or operating temperature range different in substitutes?
A5: Both substitutes specify 85% efficiency and an operating temperature range of -40°C to 105°C (with derating), compared to 84% for the main part.

Q6: What is the approved application for the substitutes?
A6: All listed products specify ITE (Commercial) applications per the input parameters.

Q7: Can substitutes be interchanged directly regarding mechanical and electrical design?
A7: Interchange is determined strictly by matching key parameters as listed. Mechanical footprint and output voltage configuration differences must be reviewed against design requirements.
