ISA2405-H Equivalent & Substitute Parts Reference

Part Overview

The ISA2405-H (XP Power) is an isolated module DC DC converter providing dual outputs of +5V and -5V at 100mA each, with a 21.6V to 26.4V input voltage range and 1W power output. It is housed in a 10-SMD Module package measuring 0.60" x 0.33" x 0.29" (15.2mm x 8.3mm x 7.3mm), offers 3kV isolation, and is suited for ITE (Commercial) applications. The product status is Obsolete, creating the need to identify compliant and available alternative models with matching electrical, mechanical, and regulatory characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute DC DC converter modules for ISA2405-H are grouped strictly based on a matching set of allowed parameters: number of outputs, input voltage range, output voltages and currents, total power, isolation voltage, efficiency threshold, operating temperature range, mounting style, package/case and dimensions, application suitability, and compliance status. Only parts matching these critical electrical, mechanical, and regulatory specifications are listed as direct substitutes.

Key parameters used for grouping:

• Number of outputs (Dual: 5V, -5V)
• Input voltage range (21.6V - 26.4V)
• Output voltages and currents (5V/100mA, -5V/100mA)
• Maximum output power (1W)
• Isolation voltage (3 kV)
• Efficiency (≥80%)
• Operating temperature (-40°C to 105°C)
• Mounting type and package/case (Surface Mount, 10-SMD Module, 6 Leads)
• Physical dimensions
• Application: ITE (Commercial)
• Compliance: ROHS3 Compliant

Engineering Selection Recommendations

ISA2405-H is classified as Obsolete. E2405XT-1WR3 is Active and provides all listed parameters equivalent to or exceeding those of the ISA2405-H, including ROHS3 compliance. E2405XT-1WR3 carries listed approval agency certifications (CB, CE, cURus, UL) and meets HTSUS and ECCN codes as supplied.

Frequently Asked Questions (FAQ)

Q: What are the primary criteria for selecting a substitute for ISA2405-H?
A: Substitution is based strictly on output configuration, input voltage range, output voltages and currents, total power, isolation voltage, efficiency, operating temperature, package, mounting method, dimensions, application rating, and compliance status.

Q: Can I use E2405XT-1WR3 in the same PCB footprint as ISA2405-H?
A: E2405XT-1WR3 uses the same mounting type and 10-SMD Module, 6 Leads package, with closely matching dimensions.

Q: Does E2405XT-1WR3 meet the same isolation and compliance requirements as ISA2405-H?
A: E2405XT-1WR3 provides 3kV isolation voltage and is ROHS3 compliant, consistent with the ISA2405-H.

Q: Are there differences in efficiency or temperature range?
A: E2405XT-1WR3 has an efficiency of 82%, which is greater than ISA2405-H’s 80%. Both support -40°C to 105°C operation, though E2405XT-1WR3 specifies derating within this range.

Q: Are the application categories the same?
A: Both parts are suitable for ITE (Commercial) applications.

Q: Is the substitute part MSL equivalent?
A: E2405XT-1WR3 lists Moisture Sensitivity Level as Not Applicable, whereas ISA2405-H is specified as MSL 1 (Unlimited). Both are suitable for standard surface mount assembly.
