Equivalent & Substitute Parts Reference: PDQ2-D24-S5-S

Part Overview

The CUI Inc. PDQ2-D24-S5-S is an isolated DC-DC converter module designed for ITE (Commercial) applications. It delivers a single regulated 5V output at up to 400mA from an 18V to 36V input range, with a maximum power output of 2W. Key features include remote On/Off control, overcurrent protection (OCP), and short circuit protection (SCP). The PDQ2-D24-S5-S is active, widely stocked, and RoHS compliant.

Alternative models are necessary for risk mitigation, supply chain continuity, and design flexibility. Substitution is strictly limited to parts matching electrical parameters, package type, mounting, compliance, and core features.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for DC-DC converter modules are grouped strictly by the following parameters:

• Input Voltage Range (18V to 36V)
• Output Voltage (5V)
• Output Current (400mA maximum)
• Output Power (2W maximum)
• Isolation Voltage (1.5 kV)
• Mounting Type (Through Hole)
• Package / Case (8-SIP Module, 7 Leads)
• Key Features (Remote On/Off, OCP, SCP)
• Compliance and Product Status (RoHS, REACH, Active)
• Physical Dimensions
• Application Category (ITE Commercial)

Only parts matching all of the above parameters are considered substitutes.

Parameter Comparison

Engineering Selection Recommendations

Only parts with an active status and compliance certifications (RoHS, REACH) are included. Both the PDQ2-D24-S5-S and SPAN02B-05 meet ECCN EAR99, HTSUS 8504.40.9580, and ITE commercial application criteria. Substitute parts are suitable if all comparison parameters strictly match.

Frequently Asked Questions (FAQ)

Which electrical parameters must match for substitution?
Input voltage range, output voltage, output current, maximum power, and isolation voltage must be identical.

Why is package and mounting type required to match?
Physical compatibility ensures correct installation, consistent mechanical performance, and integration in standardized PCB layouts.

What certifications influence substitute acceptance?
RoHS and REACH compliance are required for regulatory approval and global supply chain compatibility.

Are additional device features included in substitution logic?
Only features explicitly listed, such as Remote On/Off, OCP, and SCP, are considered. Additional features outside this set do not affect substitute selection.

How do operating temperature ranges impact selection?
Only the specified operating temperature ranges are used when comparing substitute suitability. The substitute part must conform exactly as presented.

Does inventory status impact substitution?
Product status must be 'active' per provided documentation; inventory quantity is informative but not used in equivalence determination.

Can dimensional tolerances affect substitutability?
Physical dimensions are required to match within defined input parameter tolerances for drop-in replacement compatibility.

Are ECCN and HTSUS codes required for substitution?
Equivalent ECCN and HTSUS codes enable direct cross-referencing and regulatory alignment, which is part of the substitution criteria.
