Equivalent & Substitute Parts for ISR2405A

Part Overview

ISR2405A is a DC-DC isolated module converter manufactured by XP Power. It provides a single 5V, 600mA output from an input range of 18V to 36V with 1.5 kV isolation and 3W output power. This component is obsolete, necessitating identification of substitute models with equivalent electrical, mechanical, and environmental characteristics to ensure compatibility in legacy designs and ongoing applications.

Substitute Part Grouping Explanation

Substitute parts for the ISR2405A are identified based on equivalence in all mandatory electrical, mechanical, and environmental attributes. Criteria for substitution are as follows:

• Output voltage: 5V
• Output current: 600mA
• Output power: 3W
• Input voltage range: 18V to 36V
• Isolation voltage: 1.5 kV
• Number of outputs: 1
• Mounting type: Surface Mount
• Package: 16-SMD Module, 6 Leads
• Dimensions: 0.94" x 0.54" x 0.31"
• Features: SCP (Short Circuit Protection)
• Compliance: RoHS status and MSL
• Application: ITE (Commercial)
• Product status for ongoing supply chain considerations

These parameters ensure full functional and form-factor equivalence without the introduction of new criteria or technical interpretation.

Parameter Comparison

Engineering Selection Recommendations

Both ISR2405A and PQM3-D24-S5-M-TR are listed as obsolete. Both parts are RoHS compliant and share the same MSL rating of 1 (Unlimited), and ECCN/HTSUS classifications remain unchanged. Selection between these parts can be based on supply availability and documented compliance equivalence in accordance with RoHS and ITE (Commercial) designations. No product-specific approvals or certifications beyond the provided fields are present in the listed data.
