Equivalent & Substitute Parts for IA4812S

Part Overview

The IA4812S from XP Power is an isolated module DC-DC converter designed for ITE (Commercial) applications. It features dual outputs of +12V and -12V at 42mA, operates from a 43.2V to 52.8V input, and provides 1W of output power. The product is currently listed as obsolete, making it necessary to identify substitute parts to ensure continued system maintenance, design support, and availability for existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IA4812S are selected strictly on the basis of matching the following allowed parameters: number of outputs, output voltages, input voltage range, maximum output current, output power, isolation voltage, mounting type, package, application, operating temperature, and RoHS status. These ensure electrical, mechanical, and compliance compatibility within the isolated module DC-DC converter category.

Parameter Comparison

Engineering Selection Recommendations

TRI 3-4822 from Traco Power is considered a substitute for XP Power IA4812S based on matching output configuration (+12V and -12V, dual output), ITE (Commercial) application suitability, through-hole mounting, RoHS3 compliance, and operating temperature ranges. Both products are isolated module DC-DC converters in this category. The IA4812S is obsolete, while TRI 3-4822 is listed as active.

Frequently Asked Questions (FAQ)

Q1: What parameters must match when selecting a substitute for IA4812S?
A1: Substitute selection must strictly match the number of outputs, output voltages, input voltage range, maximum output current, output power, isolation voltage, mounting type, package style, application category, operating temperature range, and RoHS status.

Q2: Is the TRI 3-4822 mechanically compatible with products designed for IA4812S?
A2: The package and mounting type are both through-hole, but TRI 3-4822 uses a 24-DIP Module, 6 Leads package while IA4812S uses a 5-SIP Module package. Careful consideration of the mechanical footprint is required for direct PCB replacement.

Q3: Are both parts RoHS compliant?
A3: Both IA4812S and TRI 3-4822 are RoHS3 Compliant.

Q4: Does the TRI 3-4822 provide the same electrical outputs as IA4812S?
A4: Both parts provide two outputs at +12V and -12V.

Q5: How does the input voltage range compare between IA4812S and TRI 3-4822?
A5: IA4812S operates from 43.2V to 52.8V. TRI 3-4822 operates from 36V to 75V.

Q6: How does product status affect selection?
A6: IA4812S is obsolete, making TRI 3-4822, which is active, the available candidate in this category.
