Key Parameters

Substitute Part Grouping Explanation

Substitutes are grouped strictly based on electrical and mechanical compatibility parameters:

• Matching input voltage range (9V - 36V)
• Single isolated output at 5V
• Isolation voltage at 1.5kV
• Mounting type: Surface Mount; Package dimensions match
• Application: ITE (Commercial)
• Product compliance: RoHS and MSL specification

Selection is based solely on fully matching or exceeding these parameters, following the specified product category guidelines.

Parameter Comparison

Engineering Selection Recommendations

The main product ISL2405A is obsolete. The substitute ATA00A18S-L from ARTESYN / Advanced Energy offers an upgrade in output current capability while maintaining matching electrical and mechanical parameters, RoHS compliance, and surface mount packaging with identical dimensions. Moisture Sensitivity Level for the substitute is 2 (1 Year), compared to the unlimited rating of the main part. Certification status (EAR99) and HTSUS number remain compatible for regulated applications.

Frequently Asked Questions (FAQ)

Q1: Which parameters are critical for selecting substitutes for ISL2405A?
Key criteria include input voltage range, output voltage, output current rating, isolation voltage, mounting type, package dimensions, operating temperature range, and compliance specifications.

Q2: Is the ATA00A18S-L a direct replacement for ISL2405A with regard to footprint and mechanical outline?
Both components share the same 16-SMD Module format and identical dimensions (0.94" x 0.54" x 0.31"), supporting direct PCB pad compatibility; however, lead configuration differs.

Q3: What compliance and certifications are matched between ISL2405A and ATA00A18S-L?
Both parts are RoHS compliant and classified under ECCN EAR99 and HTSUS 8504.40.9580.

Q4: Does the increase in output current in the ATA00A18S-L cause compatibility issues?
ATA00A18S-L supports up to 600mA, exceeding the 300mA required by ISL2405A. Substitute selection remains within allowed parameters.

Q5: Are there notable package differences regarding the number of leads?
ISL2405A uses a 16-SMD Module, 6 Leads; ATA00A18S-L uses 16-SMD Module, 7 Leads. Mechanical sizing matches, with minor lead count variation.

Q6: Do the Moisture Sensitivity Levels affect handling or storage requirements?
ISL2405A is rated MSL 1 (Unlimited), whereas ATA00A18S-L is rated MSL 2 (1 Year); this parameter may influence storage conditions.
