ISQ2405A Equivalent & Substitute Parts Reference

Part Overview

The ISQ2405A is an isolated DC-DC converter module manufactured by XP Power, designed to deliver a single 5V output at up to 400mA from a 21.6V to 26.4V input. It features 6 kV isolation voltage and is provided in a surface mount 16-SMD module package. The ISQ2405A is now designated Obsolete, and sourcing replacements is required to maintain system functionality and design continuity. Replacement parts must match electrical and mechanical parameters critical to application compatibility.

Substitute Part Grouping Explanation

Substitutes are determined by matching critical parameters including: isolation type, output voltage, current rating, input voltage range, output power, voltage isolation, number of outputs, surface mount package, application category, operating temperature, and environmental compliance. Only parts with these parameters strictly matching or exceeding those of ISQ2405A are listed.

Key substitute parameters assessed:

  • Type: Isolated Module
  • Output: 5V, 1 Output
  • Input Range: 21.6V–26.4V or wider
  • Output Current: ≥400mA
  • Isolation Voltage: ≥6 kV
  • Surface Mount Package
  • Application: ITE (Commercial)
  • Temperature Range: -40°C to 85°C
  • RoHS Compliance

Engineering Selection Recommendations

The ISQ2405A DC-DC converter is obsolete. The substitute part REC3-2405SRW/H6/A/SMD-R by Recom Power is active and matches all specified electrical and compliance parameters, including voltage, output rating, isolation, surface mount design, RoHS3 compliance, and operating temperature range. Input range and output parameters are covered or exceeded by the substitute component as detailed in the comparative table.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for selecting a substitute for ISQ2405A?
A1: Key criteria include equivalent or superior voltage and current ratings, isolation type, input range, number of outputs, isolation voltage, package type, and RoHS3 compliance.

Q2: Does the substitute REC3-2405SRW/H6/A/SMD-R maintain the necessary compliance requirements?
A2: Yes. Both ISQ2405A and REC3-2405SRW/H6/A/SMD-R are ROHS3 Compliant.

Q3: Are there significant package differences between the two parts?
A3: Yes. The ISQ2405A uses a 16-SMD Module, 6 Leads package, whereas REC3-2405SRW/H6/A/SMD-R uses a 24-SMD Module, 18 Leads package. Dimensional and pinout considerations must be reviewed for mechanical compatibility.

Q4: Is the operating temperature range equivalent between the main and substitute parts?
A4: Yes. Both operate over -40°C to 85°C.

Q5: Is the substitute part electrically compatible for direct replacement?
A5: All specified electrical parameters necessary for substitution are met or exceeded. Physical layout compatibility must be verified with provided package data.
