BQ24271RGET Equivalent & Substitute Parts

Part Overview

The BQ24271RGET is an active lithium-ion battery charger IC manufactured by Texas Instruments, supplied in 24-VQFN (4x4) surface mount packaging. This single-cell charger integrates programmable charging current control with comprehensive fault protection including over-temperature, over-voltage, and short-circuit detection. The device operates across a -40°C to 85°C temperature range and communicates via I2C interface. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where the primary part becomes unavailable or inventory constraints require alternative sourcing.

Substitute Part Grouping Explanation

Substitute parts for the BQ24271RGET are classified based on alignment with the following critical parameters:

Parametric Equivalents (Direct Substitutes): BQ24270RGET and BQ24270RGER match all electrical and mechanical specifications of the BQ24271RGET. These parts share identical battery chemistry (Lithium Ion), cell count (1), maximum charging current (1.5A), battery pack voltage (3.7V), maximum supply voltage (6V), I2C interface, operating temperature range (-40°C ~ 85°C), package type (24-VFQFN Exposed Pad), and fault protection features (Over Temperature, Over Voltage, Short Circuit). The only distinction is packaging format: BQ24270RGET and BQ24270RGER are supplied in Tape & Reel format, while BQ24271RGET is also Tape & Reel. Both maintain identical electrical performance and pinout compatibility.

Manufacturer Recommended Substitute (Enhanced Capability): BQ24296RGET is designated as the manufacturer-recommended alternative. This part operates with Lithium Ion/Polymer chemistry and supports higher maximum charging current (3A) and slightly elevated maximum supply voltage (6.2V). While the BQ24296RGET shares the same package, interface, operating temperature range, and compliance certifications, its enhanced current rating and polymer chemistry support represent functional improvements rather than direct equivalence. Selection of BQ24296RGET is appropriate when application requirements permit utilization of higher charging current or polymer battery chemistry.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: BQ24270RGET and BQ24270RGER are suitable for direct substitution when the BQ24271RGET is unavailable. Both parts maintain identical electrical specifications, fault protection architecture, and compliance certifications (ROHS3, REACH Unaffected). Packaging format differences (Tape & Reel variants) do not affect electrical performance or PCB integration.

For Enhanced Performance Applications: BQ24296RGET is the manufacturer-recommended alternative when application requirements support higher charging current (3A) or polymer battery chemistry compatibility. This part is appropriate for designs where increased charging speed or extended battery chemistry support provides functional benefit. All parts maintain active product status and equivalent compliance certifications.

Compliance and Regulatory Alignment: All substitute parts carry identical RoHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory equivalence across all sourcing options.

Frequently Asked Questions (FAQ)

Q: Can BQ24270RGET and BQ24270RGER be used interchangeably with BQ24271RGET?

A: Yes. Both BQ24270 variants are parametric equivalents with identical electrical specifications, including 1.5A maximum charging current, 3.7V battery pack voltage, 6V maximum supply voltage, I2C interface, and fault protection features. Packaging format differences do not affect electrical performance or PCB compatibility.

Q: What is the primary difference between BQ24296RGET and BQ24271RGET?

A: BQ24296RGET supports higher maximum charging current (3A versus 1.5A) and operates with Lithium Ion/Polymer chemistry at 4.2V battery pack voltage. The BQ24271RGET is limited to Lithium Ion chemistry at 3.7V. Both share identical package, interface, and operating temperature specifications.

Q: Are all substitute parts available in the same packaging format?

A: All parts use 24-VFQFN Exposed Pad surface mount packaging. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® represent supply format variations that do not affect electrical or mechanical compatibility.

Q: Do substitute parts maintain the same fault protection capabilities?

A: BQ24270RGET and BQ24270RGER maintain identical fault protection (Over Temperature, Over Voltage, Short Circuit). BQ24296RGET includes Over Current protection in addition to Over Temperature and Over Voltage, providing enhanced protection architecture.

Q: Are all parts RoHS3 compliant?

A: Yes. BQ24271RGET, BQ24270RGET, BQ24270RGER, and BQ24296RGET are all ROHS3 compliant with MSL 2 (1 Year) moisture sensitivity rating.
