Frequently Asked Questions (FAQ)

Q: What are the primary criteria for substituting the PDQ2-D48-D12-S DC-DC converter?
A: Substitute models must match input voltage range (36V–75V), dual 12V/-12V output configuration, 83mA output current per rail, 2W total power, 1.5 kV isolation, package type (8-SIP Module, 7 Leads), and regulatory compliance (RoHS, REACH).

Q: Are the package size and pinout considered in these substitutions?
A: Yes, only parts with identical or extremely close physical dimensions and through-hole 8-SIP, 7-lead packages are considered substitutes to ensure mechanical and soldering compatibility.

Q: Does product status affect the suitability of substitutes?
A: Only active products are included as substitutes, ensuring ongoing supply chain reliability and long-term support.

Q: Are there differences in compliance or features that impact substitution?
A: Both models meet RoHS and REACH requirements. Variations in optional features are limited to parameters provided; for example, both include Remote On/Off, OCP, and SCP.

Q: Can these substitutes operate in the same temperature range?
A: Provided operating temperature ranges are listed for each part; ensure requirements fall within or match the specified ranges to maintain performance.

Q: Are there restrictions on mounting type when substituting?
A: Only through-hole parts of the same package type are considered, ensuring direct fit into existing PCB designs.
