ISP2403A Equivalent & Substitute Parts Reference

Part Overview

The XP Power ISP2403A is an isolated DC-DC converter module providing a single 3.3V output at up to 500mA, designed for commercial ITE applications. This product is currently classified as obsolete, which necessitates the identification and verification of equivalent or substitute models for continuity in engineering designs and maintenance. The need for substitution is dictated by product lifecycle status and ongoing RoHS compliance requirements.

Substitute Part Grouping Explanation

Substitute part grouping for the XP Power ISP2403A is determined solely by matching key electrical, mechanical, and regulatory parameters provided in the input. Parameters strictly considered for substitution include: input voltage range, output voltage and current, isolation rating, mounting type, package size and configuration, RoHS compliance, operating temperature range, and application type. The substitute, ARTESYN ATA00F18S-L, fulfills these required conditions based on the explicitly listed criteria above.

Parameter Comparison

Engineering Selection Recommendations

The ISP2403A is obsolete, making ARTESYN ATA00F18S-L the available substitute based on matching electrical specifications, compliance, certification, and mechanical format as provided. The ATA00F18S-L is currently active and RoHS compliant, supporting continuity in designs utilizing similar package dimensions, mounting method, and isolation voltage. Engineering selection is determined exclusively by the verified status and regulatory compliance in the provided data.

Frequently Asked Questions (FAQ)

Q: What criteria are used for substituting DC-DC converters in this category?
A: Substitutions are made based on matching electrical ratings (input/output voltage, current, isolation), package dimensions, mounting type, operating temperature, application type, and compliance certifications such as RoHS status.

Q: Is ATA00F18S-L compatible with designs using ISP2403A?
A: ATA00F18S-L shares equivalent output voltage, isolation rating, mounting method, package size, and application specification as ISP2403A. It operates within the same temperature range and provides comparable electrical characteristics.

Q: Do differences in input voltage range affect substitutability?
A: ATA00F18S-L supports a wider input voltage range (9V–36V) compared to ISP2403A (18V–36V). For applications where the input voltage remains within the overlapping range, the substitute is aligned with the original specification.

Q: What are the package and footprint considerations when substituting these modules?
A: Both modules utilize the same 16-SMD surface mount form factor with near-identical size/dimension attributes. The difference in lead count (6 vs 7) should be verified against board layout requirements as per the provided data.

Q: What compliance information is relevant for substitution?
A: RoHS compliance and product status (active vs obsolete) are directly reflected in selection criteria. Both ISP2403A and ATA00F18S-L meet the specified RoHS status in their category.
