BQ25886RGET Equivalent & Substitute Parts

Part Overview

The BQ25886RGET is an active lithium-ion/polymer battery charger IC from Texas Instruments, designed for 2-cell battery pack charging applications. This Surface Mount device operates within the -40°C to 85°C temperature range and provides integrated fault protection including over-current, over-temperature, over-voltage, and short-circuit detection. The part is ROHS3 compliant and maintains unlimited moisture sensitivity level (MSL 1), making it suitable for industrial and consumer applications requiring reliable charge management.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different packaging formats from the same manufacturer.

Substitute Part Grouping Explanation

Substitution eligibility for the BQ25886RGET is determined by strict equivalence across the following criteria:

• Identical base product number (BQ25886)
• Matching battery chemistry (Lithium Ion/Polymer)
• Identical cell count (2 cells)
• Identical maximum charge current (2.2A)
• Identical maximum battery pack voltage (9.2V)
• Identical maximum supply voltage (6.2V)
• Identical package and case specification (24-VFQFN Exposed Pad)
• Identical mounting type (Surface Mount)
• Identical operating temperature range (-40°C ~ 85°C)
• Matching regulatory compliance (ROHS3, REACH Unaffected)

Packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) do not affect electrical or mechanical compatibility and represent logistics variations only.

Parameter Comparison

Engineering Selection Recommendations

The BQ25886RGER is a direct parametric equivalent to the BQ25886RGET. Both parts maintain identical electrical specifications, mechanical compatibility, and regulatory certifications. The distinction between these part numbers reflects packaging and distribution format only:

• BQ25886RGET: Supplied in Tape & Reel format
• BQ25886RGER: Supplied in Cut Tape and Digi-Reel format

Both parts are Active status products from Texas Instruments with ROHS3 compliance and REACH unaffected designation. Selection between these variants should be based on procurement requirements, inventory availability, and supply chain logistics rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can BQ25886RGER be used as a direct replacement for BQ25886RGET in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel). PCB design, schematic, and assembly processes require no modification.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts share identical maximum charge current (2.2A), battery pack voltage rating (9.2V), supply voltage rating (6.2V), and operating temperature range (-40°C to 85°C).

Q: Do both parts support the same fault protection features?

A: Yes. Both BQ25886RGET and BQ25886RGER include identical fault protection: over-current, over-temperature, over-voltage, and short-circuit detection.

Q: What is the significance of the packaging format difference?

A: Packaging format affects supply chain logistics and handling. Tape & Reel (TR) is standard for high-volume automated assembly. Cut Tape (CT) and Digi-Reel are alternative distribution formats. The actual component and its performance remain unchanged.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, classified as EAR99, and share the same HTSUS code (8542.39.0001).

Q: Can I mix BQ25886RGET and BQ25886RGER in the same production batch?

A: Yes. Since both parts are parametrically identical, they can be used interchangeably without affecting circuit performance or reliability.
