Texas Instruments BQ24103ARHL
BQ24103ARHL variants from Texas Instruments
BQ24103ARHL Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
BQ24103ARHL is a Texas Instruments order-code family — not a single orderable MPN. This page lists 4 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.
Switching Battery Charger Li-Ion/Li-Pol/NiCd/NiMH 2000mA 4.2V/8.4V 20-Pin VQFN EP T/R Other listed variants describe: Standalone Synchronous Switch-mode Li-ion charger with 2A FET 20-VQFN -40 to 85; 2A Synchronous Buck Battery Charger IC, 1-2 Cell, 8.4V, VQFN.
Suffix examples in this family: R, RG4, T, TG4. 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: BQ24103ARHLR, BQ24103ARHLRG4, BQ24103ARHLT, BQ24103ARHLTG4.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 4 distinct suffix patternsExamples: R, RG4, T, TG4. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — 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 Code Differences
How suffixes on BQ24103ARHL map to package, grade, and reel options.
BQ24103ARHL 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, RG4, T, TG4.
Full MPN examples: BQ24103ARHLR, BQ24103ARHLRG4, BQ24103ARHLT, BQ24103ARHLTG4.
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 BQ24103ARHL Microcontrollers
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 BQ24103ARHL, 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 "BQ24103ARHL" — include the full suffix (e.g. R, RG4, T). RFQ with reel/tube preference and required date code.
