IA4805S Equivalent & Substitute Parts Reference

Part Overview

The IA4805S, manufactured by XP Power, is an isolated module DC-DC converter delivering dual outputs of +5V and -5V at 100mA each, with an input voltage range of 43.2V to 52.8V. This module provides 1W of power, offers 1 kV isolation, and is suitable for ITE (Commercial) applications. The part is obsolete, making it necessary to identify compatible alternative DC DC converter models to ensure continuity in systems requiring equivalent electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based only on parameters explicitly provided for DC DC converter isolated modules in this category. Critical comparison parameters include: module type, number of outputs, voltage input range, output voltages, output currents, output power, isolation voltage, applications, mounting type, package/case, operating temperature, and RoHS compliance. Substitute models must match or exceed the electrical and mechanical requirements within these listed key parameters.

Parameter Comparison

Engineering Selection Recommendations

The IA4805S part is obsolete; therefore, selection of an equivalent substitute is based on matching type, outputs, input and output voltage, isolation, output current, mounting style, package/case, temperature range, and RoHS status as explicitly provided. The PDQ2-D48-D5-S from CUI Inc. is active, maintains RoHS compliance, and provides compliance to the specified applications (ITE Commercial). Selection can be done based on the above comparison and regulatory status.

Frequently Asked Questions (FAQ)

Q1: What parameters are essential when selecting a substitute for the IA4805S DC DC converter module?
A1: Key parameters include type, number of outputs, input voltage range, output voltage levels, output current, power rating, isolation voltage, application category, mounting type, package/case style, operating temperature, and RoHS compliance.

Q2: Is the PDQ2-D48-D5-S a direct plug-in replacement for the IA4805S?
A2: The PDQ2-D48-D5-S matches the functional type, outputs, input and output voltage levels, and application category. Variations are present in output current capability, power rating, voltage isolation, and module package/case. Dimensional and lead configuration should be verified against assembly requirements.

Q3: How does operating temperature range affect substitute selection?
A3: Substitute selection should use modules with an operating temperature range that meets or exceeds the IA4805S’s -40°C ~ 85°C. The PDQ2-D48-D5-S supports -40°C ~ 100°C.

Q4: What certification and compliance considerations apply?
A4: Selection is based on RoHS compliance and application type (ITE Commercial) as specified. The substitute part PDQ2-D48-D5-S is RoHS compliant and intended for equivalent application usage.

Q5: Are mechanical package differences relevant when selecting substitutes?
A5: Substitute modules should be checked against the original package/case and mounting type to ensure fit within system mechanical constraints. The IA4805S uses a 5-SIP module and the PDQ2-D48-D5-S uses an 8-SIP module with 7 leads.
