A1102LLHL Overview

What changes between part numbers, and what to check before you lock the BOM — Magnetic Sensors.

Key Features

Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
2 distinct suffix patternsExamples: T-T, X-T. Decode suffix meaning in the ordering notes under the variant table.

Target Applications

Magnetic Sensors — design-in and field replacement
BOM scrub where only the base prefix is known but suffix is TBD
Second-source checks when the original MPN is constrained

Ordering Variants

Compare 2 A1102LLHL part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

Part Number	Description	Manufacturer	Lifecycle	RoHS	Availability	Action
A1102LLHLT-T	Analog Unipolar Switch, BICMOS, SOT-23, 24V, 25mA	Allegro MicroSystems	Active	Compliant	In Stock	RFQ
A1102LLHLX-T	Hall Effect Sensor 25mA Unipolar 5V/9V/12V/15V/18V Automotive 3-Pin SOT-23W T/R	Allegro MicroSystems	Active	Compliant	In Stock	RFQ

How to Choose the Right A1102LLHL Magnetic Sensors

📦

Match the footprint first

Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For A1102LLHL, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.

🌡️

Temp grade letter matters

Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.

🔢

Copy the full MPN

Do not BOM only "A1102LLHL" — include the full suffix (e.g. T-T, X-T). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the A1102LLHL product family.

Is A1102LLHL a single part I can order, or a family prefix?

A1102LLHL is a base / family code from Allegro MicroSystems. You order a full MPN such as A1102LLHLT-T, A1102LLHLX-T. The variant table lists 2 orderable lines with different suffixes.

What do the suffix letters on A1102LLHL part numbers mean?

Listed suffix fragments include: T-T, X-T. Typically they encode package (see Package column), temperature grade, and tape/reel option. Always decode on the Allegro MicroSystems datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of A1102LLHL variants?

Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.

What should I send for an RFQ on A1102LLHL?

Full manufacturer MPN (not just A1102LLHL), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.

Where is the A1102LLHL datasheet?

Use the datasheet link in the page header. Cross-check electrical curves (SOA, saturation voltage, etc.) against your operating point — the table summarizes order codes, not every graph in the PDF.
