BQ24163RGER Equivalent & Substitute Parts

Part Overview

The BQ24163RGER is a single-cell lithium-ion/polymer battery charger IC manufactured by Texas Instruments, housed in a 24-VQFN (4x4) surface mount package with exposed pad. This active product integrates constant-current/constant-voltage charging control with I2C interface capability, fault protection against over-temperature and over-voltage conditions, and programmable charging current up to 2.5A. The BQ24163RGER is essential for portable and embedded applications requiring compact, integrated battery management. Substitute parts are identified when they maintain identical electrical specifications, thermal operating range, package geometry, and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BQ24163RGER is determined by strict equivalence across the following critical parameters:

Battery chemistry and cell count must remain Lithium Ion/Polymer, single-cell configuration. Maximum charging current must equal 2.5A. Battery pack voltage must be 3.4V. Maximum supply voltage must not exceed 10V. Interface protocol must be I2C. Operating temperature range must span -40°C to 85°C. Package geometry must be 24-VFQFN with exposed pad in surface mount configuration. Fault protection features must include over-temperature and over-voltage detection. RoHS3 compliance and MSL 2 (1 Year) rating must be maintained.

The BQ24163RGET meets all these criteria and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the BQ24163RGER and BQ24163RGET are active products from Texas Instruments with identical electrical and mechanical specifications. Both maintain ROHS3 compliance and MSL 2 (1 Year) rating, ensuring compatibility with standard manufacturing and storage protocols. Selection between these parts may be based on inventory availability, lead time, or supply chain considerations, as no technical differentiation exists between them.

Frequently Asked Questions (FAQ)

Q: Can the BQ24163RGET replace the BQ24163RGER in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, operating temperature range, package geometry, and compliance certifications. Direct substitution is supported without design modification.

Q: What determines if a part is a valid substitute for the BQ24163RGER?

A: A valid substitute must maintain identical battery chemistry (Lithium Ion/Polymer), single-cell configuration, 2.5A maximum charging current, 3.4V battery pack voltage, 10V maximum supply voltage, I2C interface, -40°C to 85°C operating temperature, 24-VFQFN exposed pad package, over-temperature and over-voltage protection, ROHS3 compliance, and MSL 2 (1 Year) rating.

Q: Are there differences in the package or pin configuration between BQ24163RGER and BQ24163RGET?

A: No. Both parts use the identical 24-VFQFN (4x4) surface mount package with exposed pad. Pin configuration and PCB footprint requirements are identical.

Q: What is the significance of the MSL 2 rating?

A: MSL 2 indicates a moisture sensitivity level requiring storage at ≤30°C and ≤60% relative humidity, with a floor life of 1 year. Both parts share this rating and require identical handling protocols.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that inventory and supply chain logistics support the substitution. Both parts meet identical technical and compliance requirements for single-cell lithium-ion/polymer battery charging applications.
