ACS711ELCT Overview
What changes between part numbers, and what to check before you lock the BOM — Sensors.
ACS711ELCT is a Allegro MicroSystems order-code family — not a single orderable MPN. This page lists 2 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
Hall Effect Current Sensor 12.5A SOIC 100kHz Other listed variants describe: Hall Effect Current Sensor, 25A, 100kHz, SOIC.
Suffix examples in this family: R-12AB-T, R-25AB-T. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Example MPNs: ACS711ELCTR-12AB-T, ACS711ELCTR-25AB-T.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: R-12AB-T, R-25AB-T. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- 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 ACS711ELCT 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 |
|---|---|---|---|---|---|---|
| ACS711ELCTR-12AB-T | Hall Effect Current Sensor 12.5A SOIC 100kHz | Allegro MicroSystems | Active | Compliant | In Stock | |
| ACS711ELCTR-25AB-T | Hall Effect Current Sensor, 25A, 100kHz, SOIC | Allegro MicroSystems | Active | Compliant | In Stock |
Ordering Code Differences
How suffixes on ACS711ELCT map to package, grade, and reel options.
ACS711ELCT uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: R-12AB-T, R-25AB-T.
Full MPN examples: ACS711ELCTR-12AB-T, ACS711ELCTR-25AB-T.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right ACS711ELCT 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 ACS711ELCT, 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 "ACS711ELCT" — include the full suffix (e.g. R-12AB-T, R-25AB-T). RFQ with reel/tube preference and required date code.
