IA4824S Equivalent & Substitute Parts Engineering Reference

Part Overview

The XP Power IA4824S is an isolated DC-DC converter module delivering dual output voltages of +24V and -24V at a maximum output current of 21mA (1W power rating). This device is designed for ITE (Commercial) applications, features through-hole mounting, adheres to ROHS3 compliance, and has an isolated input voltage range of 43.2V to 52.8V. The IA4824S is classified as obsolete, which necessitates identifying substitute models to support ongoing production, repairs, and design maintenance in applications originally specifying this part.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the XP Power IA4824S is strictly handled by matching the following key parameters: output voltage configuration (+24V and -24V), number of outputs, isolated topology, through-hole mounting, input voltage range compatibility, output current/power capability, voltage isolation rating, operating temperature range, RoHS (or similar) compliance, and package form factor. Only parts with explicitly stated parameter alignment in these categories are considered viable substitutes.

Parameter Comparison

Engineering Selection Recommendations

The XP Power IA4824S is classified as obsolete; selecting a substitute part requires that the alternative is active and maintains the necessary compliance status (RoHS or similar). URA4824YMD-10WR3 from Mornsun America, LLC is active, RoHS compliant, and meets the isolation and dual-output requirements, making it suitable to fulfill functional replacement where packaging and mounting criteria are addressed according to the listed parameters.

Frequently Asked Questions (FAQ)

Q1: What are the primary substitution criteria for the XP Power IA4824S?
A1: Substitute parts must provide dual outputs of +24V and -24V, isolated topology, through-hole mounting, compatible input voltage range, output current/power sufficient for the application, operating temperature of -40°C to 85°C, and RoHS (or similar) compliance.

Q2: Is there a difference in package size or type between IA4824S and URA4824YMD-10WR3?
A2: Yes. IA4824S is supplied in a 5-SIP Module package (0.76" x 0.24" x 0.40"), while URA4824YMD-10WR3 uses a 6-DIP Module (1.00" x 1.00" x 0.46"). Physical layout and footprint differences must be considered for board compatibility.

Q3: Are both IA4824S and URA4824YMD-10WR3 compliant with RoHS standards?
A3: Yes. IA4824S is ROHS3 Compliant; URA4824YMD-10WR3 is RoHS Compliant.

Q4: What status makes it critical to seek a substitute for IA4824S?
A4: The IA4824S is marked as obsolete. Substituting ensures continued product lifecycle support and availability.

Q5: Are there input voltage or power differences that affect substitution?
A5: URA4824YMD-10WR3 supports a wider input range (18V - 75V) and higher output current/power, but output voltage alignment (24V, -24V) remains exact, which is essential for functional compatibility.
