Substitute Part Grouping Explanation

The substitute part PDME2-S5-D3-S has been identified based strictly on shared key electrical and mechanical parameters. These include output voltage configuration (3.3V and -3.3V), number of outputs (2), maximum power rating (2W), isolation voltage (1.5kV), mounting type (Through Hole), and compliance (RoHS and REACH statuses). Substitute selection excludes any inference and is limited to parameters explicitly available for both parts.

Engineering Selection Recommendations

Substitution is determined by product status, regulatory compliance, and availability. The PDM2-S5-D3-S is obsolete, making the active PDME2-S5-D3-S a suitable substitute. Both parts maintain alignment on RoHS and REACH compliance, supporting continued use in regulated applications. Certifications and international trade compliance (EAR99, HTSUS) remain matched. Package footprint and output characteristics require direct validation with application requirements, referencing only provided dimensional and lead information.

Frequently Asked Questions (FAQ)

Q1: What determines substitute compatibility for isolated DC-DC converters?
A1: Substitute compatibility is determined by matching output voltage, output current, power rating, isolation voltage, mounting type, and package dimensions as per the explicitly listed parameters.

Q2: Are the package and pinout for PDM2-S5-D3-S and PDME2-S5-D3-S identical?
A2: Both are SIP modules with 5 leads; however, main part is specified as 6-SIP and substitute as 7-SIP. Dimensional details are similar but may differ in minor mechanical aspects as per provided data.

Q3: Can the substitute part operate under the same temperature range?
A3: Both parts list an operating temperature range of -40°C to 105°C, with the substitute specifying operation "with derating."

Q4: How does regulatory compliance compare between PDM2-S5-D3-S and PDME2-S5-D3-S?
A4: Both parts are RoHS and REACH compliant, maintain the same ECCN classification, and share HTSUS codes.

Q5: What considerations should be made regarding part status and inventory?
A5: PDM2-S5-D3-S is obsolete. PDME2-S5-D3-S is active and available. Current inventory levels are provided for both parts.
