S-1009N17I-N4T1U Equivalent & Substitute Parts

Part Overview

The S-1009N17I-N4T1U is a voltage supervisor IC manufactured by ABLIC Inc., classified as a Power Management (PMIC) component. This single-channel voltage detector operates with a 1.7V threshold and provides open drain or open collector output with active low reset functionality. The device is housed in an SC-82A (SOT-343) surface mount package and maintains Active product status. Alternative models may be required due to inventory constraints, supply chain considerations, or specific application requirements while maintaining identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can the S-80817CNNB-B8CT2U be used as a direct replacement for the S-1009N17I-N4T1U?

A: Yes. Both parts are parametric equivalents with identical voltage threshold (1.7V), output configuration (open drain or open collector), reset polarity (active low), operating temperature range (-40°C to 85°C), and package type (SC-82A, SOT-343). No circuit modifications are required.

Q: Are there any differences in compliance or certifications?

A: No. Both parts carry identical ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification. Moisture sensitivity level is 1 (Unlimited) for both devices.

Q: What is the difference between the part numbers S-1009 and S-80817?

A: These represent different base product series within ABLIC Inc.'s voltage supervisor portfolio. The S-80817CNNB-B8CT2U belongs to the S-808xxC series, while the S-1009N17I-N4T1U belongs to the S-1009 series. Despite different series designations, both parts meet identical parametric specifications for this application.

Q: Is the SC-82A package the same as SOT-343?

A: Yes. SC-82A and SOT-343 refer to the same surface mount package configuration used for both parts.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Identical package type, pin configuration, and electrical specifications ensure direct PCB compatibility without layout or design modifications.
