Equivalent & Substitute Parts for PDQ2-D48-S12-S

Part Overview

The PDQ2-D48-S12-S from CUI Inc. is an isolated DC-DC converter module. It provides a single 12V output at up to 167mA with a 2W maximum power rating, accepting an input voltage range from 36V to 75V. This module is housed in an 8-SIP through-hole package and includes features for protection and control. The part is currently active, but identifying substitute models is important for ensuring continuity of supply, design flexibility, and mitigating supply chain constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for DC-DC converters are grouped based on strict equivalence of electrical and mechanical parameters. The parameters determining allowable substitution include: input voltage range, output voltage and current, power rating, isolation voltage, efficiency, number of outputs, features, mounting type, package form factor, and temperature range. Compliance statuses such as RoHS, REACH, MSL, and product status must also match.

Parameter Comparison

Engineering Selection Recommendations

Both PDQ2-D48-S12-S and SPAN02C-12 are active products and comply with RoHS and REACH requirements. Each shares the same category, power ratings, voltage ranges, current output, package type, and form factor. Both specify unlimited MSL and have identical ECCN and HTSUS codes. Product selection can be based strictly on matching compliance, inventory status, and required certificates as provided.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match when substituting a DC-DC converter module?
A1: Input voltage range, output voltage and current, power rating, isolation voltage, efficiency, number of outputs, mounting type, package, and application must all match. Compliance and certification statuses must also correspond.

Q2: Are 8-SIP module, 7-lead packages between different manufacturers interchangeable?
A2: Provided the physical dimensions, lead configuration, and mounting type are identical as specified in the parameters, the packages are interchangeable.

Q3: Do variations in features such as additional protection functions affect substitution?
A3: Additional features are permissible for substitution if all required baseline features and ratings are present and matched as per the input data.

Q4: Should compliance certificates like RoHS or REACH be considered in substitution?
A4: Yes, substituting parts must match the specified compliance and certification statuses.

Q5: Can substitutions be made if the substitute product has a reduced maximum operating temperature?
A5: Substitution is allowed only when the specified operating temperature range meets the application's requirements as per the input. Only parameters explicitly provided in the input determine eligibility.
