• Voltage - Input (Max): 13.2V
• Voltage - Output 1: 5V
• Current - Output (Max): 400mA
• Power (Watts): 2 W
• Voltage - Isolation: 1.5 kV
• Mounting Type: Through Hole
• Operating Temperature: -40°C ~ 105°C (With Derating)

Parameter Comparison

Engineering Selection Recommendations

The primary selection driver is the main part’s obsolete status. PDME2-S12-S5-D and PDME2-S12-S5-S are active and meet the equivalent electrical and mechanical requirements, including mounting type, output configuration, power, and isolation voltage. Both substitutes have RoHS compliance and ITE (Commercial) application compatibility. PDME2-S12-S5-S provides full RoHS3 and REACH compliance, matching the environmental status requirements indicated for PDM2-S12-S5-D.

Frequently Asked Questions (FAQ)

Q1: What critical parameters must match when substituting DC-DC converters like PDM2-S12-S5-D?
A1: Type, number of outputs, input and output voltages, maximum output current, power rating, voltage isolation, mounting type, and operating temperature are essential for direct substitution.

Q2: Does the package difference between DIP and SIP affect electrical compatibility?
A2: While electrical parameters match, package and pinout may vary. Verify mechanical fit and pin compatibility when transitioning between DIP and SIP packages.

Q3: Are RoHS and REACH statuses important in substitution?
A3: RoHS and REACH compliance should match application, assembly, and end-product regulatory requirements. Substitutes listed provide equivalent environmental status where specified.

Q4: Are the approval agency and standard number relevant for all applications?
A4: Select substitutes with matching agency approvals and standards in regulated or certified applications to ensure product acceptance and maintain compliance.

Q5: Is there any difference in efficiency between the main and substitute parts?
A5: PDME2-S12-S5-D and PDME2-S12-S5-S have a stated efficiency of 82% compared to 84% for PDM2-S12-S5-D. Evaluate system-level heat dissipation requirements if this parameter is critical.
