Equivalent & Substitute Parts Reference: ISA2409

Part Overview

The XP Power ISA2409 is an isolated module DC-DC converter designed for ITE (Commercial) applications. Its key characteristics include dual outputs of +9V and -9V, each rated at 56mA maximum, with a total output power of 1W. The module accepts input voltages between 21.6V and 26.4V, features 1.5kV isolation, and is offered in a compact surface mount 10-SMD package. The product is marked as obsolete, necessitating the identification of suitable substitute parts for continued use in designs and production.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for ISA2409 are determined strictly by matching the following parameters:

• Manufacturer: XP Power
• Type: Isolated Module
• Number of Outputs: 2
• Voltage Input Range: 21.6V to 26.4V
• Output Voltages and Current Rating
• Output Power: 1W
• Isolation Voltage: 1.5kV
• Application: ITE (Commercial)
• Mounting Type: Surface Mount
• Package / Case: 10-SMD Module, 6 Leads
• Dimensions

Parts within the IAS01 series, specifically IAS0124D09 and IAS0124D05, meet these criteria and are applicable substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts IAS0124D09 and IAS0124D05 are marked as active. IAS0124D09 matches both output voltages and current ratings, and IAS0124D05 provides lower output voltages with higher current. IAS0124D09 and IAS0124D05 possess CE, UKCA, and UL approvals under standard 62368-1, and are ROHS3 compliant. ISA2409 does not list explicit certifications or RoHS status. For compliance-sensitive applications, substitute products with known certifications and RoHS status are preferable.

Frequently Asked Questions (FAQ)

Q: What are the most critical criteria for substituting ISA2409?
A: The most critical criteria are matching the input voltage range, output voltage(s), current rating, isolation voltage, product type, mounting type, package, and intended application.

Q: Are output voltages always interchangeable between models?
A: Substitutes must match the required output voltage(s) for compatibility. IAS0124D09 provides 9V/-9V outputs, which are identical to ISA2409, while IAS0124D05 provides 5V/-5V outputs.

Q: Is the mechanical footprint identical?
A: The package style and dimensions between ISA2409, IAS0124D09, and IAS0124D05 are very similar, all being surface mount 10-SMD modules with 6 leads, allowing mechanical compatibility in most cases.

Q: How does product status affect selection?
A: Since ISA2409 is obsolete, selection should favor active substitutes like IAS0124D09 and IAS0124D05.

Q: Are additional certifications relevant in the substitution process?
A: IAS0124D09 and IAS0124D05 specify CE, UKCA, and UL certifications and ROHS3 compliance. ISA2409 does not list certifications; consideration should be given to substitute parts with explicit regulatory compliance where required.

Q: Can IAS0124D09 be considered a direct replacement?
A: IAS0124D09 matches all primary electrical and mechanical parameters of ISA2409, supporting direct replacement strictly based on provided specifications.
