BQ25887RGET Equivalent & Substitute Parts

Part Overview

The BQ25887RGET is an active, production-grade battery balancer IC designed for lithium-ion 2-cell battery management systems. Manufactured by Texas Instruments, this component integrates over-current, over-temperature, and over-voltage protection with I2C interface control. The device is supplied in 24-VQFN (4x4) surface-mount packaging with an exposed pad for thermal management.

Finding equivalent and substitute parts is necessary to address supply chain flexibility, packaging format preferences, and inventory availability while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BQ25887RGET is determined by strict equivalence across the following critical parameters:

• Base product number (BQ25887)
• Functional classification (Battery Balancer)
• Battery chemistry support (Lithium Ion)
• Cell count (2-cell configuration)
• Fault protection features (Over Current, Over Temperature, Over Voltage)
• Communication interface (I2C)
• Operating temperature range (-40°C to 85°C)
• Package type (24-VQFN with exposed pad)
• Regulatory compliance (ROHS3, REACH Unaffected)

The substitute part BQ25887RGER shares all electrical and mechanical specifications with the main part. The only difference is the packaging format: BQ25887RGET is supplied in Tape & Reel (TR) format, while BQ25887RGER is supplied in Cut Tape (CT) & Digi-Reel® format. Both formats contain identical die and lead-frame configurations suitable for automated assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Both BQ25887RGET and BQ25887RGER are active production parts manufactured by Texas Instruments with identical electrical specifications and regulatory compliance status. Selection between these parts is determined by packaging format requirements and supply chain logistics.

The BQ25887RGET in Tape & Reel format is suitable for high-volume automated assembly operations requiring continuous reel feeding. The BQ25887RGER in Cut Tape & Digi-Reel® format provides flexibility for lower-volume production runs or mixed-component pick-and-place operations.

Both parts meet ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for consumer and industrial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can BQ25887RGER be used as a direct replacement for BQ25887RGET?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). Pin configuration, electrical performance, and thermal characteristics are identical.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) supplies components on continuous reels for high-speed automated assembly. Cut Tape (CT) & Digi-Reel® supplies components in shorter tape segments or alternative reel formats, suitable for lower-volume production or component kitting operations. Both formats contain the same component.

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

A: No. Both BQ25887RGET and BQ25887RGER use identical die and lead-frame configurations. Operating temperature range, I2C interface performance, fault protection thresholds, and thermal dissipation characteristics are identical.

Q: Do both parts support the same battery cell configurations?

A: Yes. Both parts are rated for 2-cell lithium-ion battery management with identical over-current, over-temperature, and over-voltage protection parameters.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 (Unlimited) indicates that these components have no moisture sensitivity constraints. They can be stored and handled without time-limited desiccant packaging or baking procedures prior to reflow soldering.

Q: Are both parts suitable for automated pick-and-place assembly?

A: Yes. Both parts are surface-mount components in 24-VQFN packaging with exposed pads. Tape & Reel format is optimized for continuous-feed pick-and-place systems, while Cut Tape & Digi-Reel® format accommodates component feeders designed for shorter tape segments or alternative reel configurations.
