Key Parameters

Substitute Part Grouping Explanation

Substitute parts are strictly selected based on match with critical electrical and mechanical parameters: input voltage range (4.5V–5.5V), output voltage (3.3V), output current (400mA), isolation (1.5kV), mounting type (through hole), package (SIP 4-lead module), and application (ITE Commercial). Substitution additionally requires that the module has similar or compatible compliance statuses (RoHS, REACH), and is currently available.

Parameter Comparison

Engineering Selection Recommendations

The original part number PDM2-S5-S3-S is listed as Obsolete, requiring selection of a substitute model. The manufacturer-recommended substitute, PDME2-S5-S3-S, matches the electrical input, output, isolation, and mounting parameters, and maintains commercial ITE application suitability. PDME2-S5-S3-S is Active, RoHS3 Compliant, and REACH Unaffected, supporting regulatory and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: What criteria define a direct substitute for PDM2-S5-S3-S?
A: Substitutes are defined by exact match of input voltage range, output voltage, output current, isolation rating, mounting type, package case, and compliance status.

Q: Will package or dimensional changes affect PCB compatibility?
A: The substitute PDME2-S5-S3-S uses a 7-SIP Module, 4 Leads package with similar dimensions (variation: 19.7mm x 7.1mm x 10.2mm). Compatibility depends on adherence to mechanical footprint.

Q: Is there any difference in performance?
A: Key electrical ratings such as input range, output voltage, output current, and isolation are consistent. Notable differences include reduced output power and efficiency.

Q: Are all regulatory and environmental statuses maintained?
A: Both parts are RoHS and REACH compliant, with MSL 1 ratings. The substitute additionally specifies ROHS3 compliance.

Q: Is PDME2-S5-S3-S approved for ITE (Commercial) applications?
A: Yes, both main and substitute parts are designated for ITE (Commercial) application.

Q: Are there further substitute options listed?
A: Only PDME2-S5-S3-S is specified as manufacturer-recommended within the provided parameters.
