Substitute Part Grouping Explanation
All substitute parts listed maintain identical electrical and mechanical parameters as the BQ7790500PWR. Substitution eligibility is determined by the following criteria:
- Battery Chemistry: Lithium Ion
- Cell Count: 3 ~ 5 cells
- Fault Protection: Over Current, Over Temperature, Over/Under Voltage, Short Circuit
- Operating Temperature Range: -40°C ~ 85°C
- Package Type: 20-TSSOP (0.173", 4.40mm Width)
- Mounting Type: Surface Mount
- RoHS3 Compliance
- MSL Rating: 2 (1 Year)
- Product Status: Active
The primary differentiation among substitute parts is packaging format (Cut Tape with Digi-Reel® versus Tape & Reel) and inventory availability. All parts are manufactured by Texas Instruments and carry identical functional specifications.

Frequently Asked Questions (FAQ)
Q: Can BQ7790502PWR be used as a direct replacement for BQ7790500PWR?
A: Yes. Both parts share identical electrical specifications, battery chemistry support (Lithium Ion, 3-5 cells), fault protection capabilities, operating temperature range (-40°C to 85°C), and 20-TSSOP package dimensions. The primary difference is packaging format: BQ7790502PWR is supplied in Tape & Reel format while BQ7790500PWR is supplied in Cut Tape with Digi-Reel®.
Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging?
A: Both are surface mount packaging formats for the same 20-TSSOP component. Cut Tape with Digi-Reel® is typically used for smaller volume orders and manual assembly, while Tape & Reel is standard for high-volume automated assembly. The electrical and mechanical specifications of the IC remain identical.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitute parts, including BQ7790500PWR, BQ7790502PWR, BQ7790508PWR, BQ7790509PWR, BQ7790512PWR, BQ7790518PWR, BQ7790521PWR, and BQ7790522PWR, are ROHS3 compliant with MSL rating of 2 (1 Year).
Q: Can these parts be used interchangeably in production?
A: Yes, provided the packaging format is compatible with your assembly process. All parts are functionally equivalent for Lithium Ion battery protection applications with 3 to 5 cell configurations.
Q: Which substitute part has the highest inventory availability?
A: BQ7790508PWR has the highest inventory at 25,400 pieces in stock.
