Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL8702AIBZ is determined by strict equivalence across the following critical parameters:

• Number of channels monitored: 4 channels
• Voltage threshold capability: Adjustable/Selectable
• Output type: Open Drain or Open Collector
• Reset configuration: Active High/Active Low with adjustable timeout
• Operating temperature range: -40°C ~ 85°C
• Package specification: 14-SOIC form factor with identical physical dimensions
• Compliance certifications: ROHS3 and REACH status alignment

The ISL8702IBZ qualifies as a direct substitute based on identical electrical specifications and package requirements. The primary distinction is product status: ISL8702IBZ is active, whereas ISL8702AIBZ is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The ISL8702IBZ is the appropriate substitute for the obsolete ISL8702AIBZ. Both parts maintain identical electrical and mechanical specifications, ensuring functional compatibility in existing designs. The ISL8702IBZ carries active product status, providing supply chain continuity and long-term availability. Both parts satisfy ROHS3 and REACH compliance requirements, supporting regulatory obligations in manufacturing and distribution.

Selection of ISL8702IBZ over ISL8702AIBZ is justified by product lifecycle considerations: the active status ensures access to current manufacturing batches, technical support, and documented supply forecasts. Packaging differences (tube versus unspecified for the original part) do not affect electrical performance or PCB integration.

Frequently Asked Questions (FAQ)

Q: Can ISL8702IBZ directly replace ISL8702AIBZ in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including channel count, threshold adjustability, output configuration, reset functionality, temperature range, and 14-SOIC package dimensions.

Q: What is the significance of the product status difference?

A: ISL8702AIBZ is obsolete, indicating discontinued manufacturing and limited availability. ISL8702IBZ is active, ensuring ongoing production and reliable supply chain access for new orders and replacements.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance and REACH status, with matching Moisture Sensitivity Level (MSL) ratings of 2 (1 Year).

Q: Does packaging format affect substitution compatibility?

A: Packaging format (tube versus other configurations) does not affect electrical performance or PCB mounting. The 14-SOIC package dimensions and surface mount characteristics are identical, ensuring seamless integration.

Q: Are there any electrical parameter differences that would prevent substitution?

A: No. All electrical parameters—voltage monitoring channels, threshold adjustability, output type, reset configuration, and operating temperature range—are identical between ISL8702AIBZ and ISL8702IBZ.
