Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BQ24004PWPRG4 are qualified based on identical electrical and mechanical parameters: lithium-ion chemistry, 2-cell configuration, 1.2A maximum charge current, 8.4V battery pack voltage, 10V maximum supply voltage, -40°C to 70°C operating temperature range, constant-current charging mode, programmable current and timer functions, over-temperature protection, and 20-PowerTSSOP package format. All substitute parts maintain ROHS3 compliance and MSL 2 rating. Substitutes differ only in product status (active vs. obsolete/discontinued) and packaging format (Cut Tape, Tape & Reel, or standard packaging).

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, BQ24005PWPR and BQ24006PWPR are preferred substitutes as both maintain active product status with Texas Instruments. BQ24005PWPR is available in Cut Tape and Digi-Reel packaging with 5914 units in stock, providing the highest inventory availability. BQ24006PWPR is available in Tape & Reel format with 859 units in stock. Both parts meet identical electrical specifications and ROHS3 compliance requirements. BQ24004PWPR remains a valid substitute for legacy applications but carries obsolete status. All three substitute parts are electrically and mechanically interchangeable with BQ24004PWPRG4 within the specified parameter set.

Frequently Asked Questions (FAQ)

Q: Can BQ24005PWPR and BQ24006PWPR be used interchangeably with BQ24004PWPRG4?

A: Yes. Both parts meet identical electrical and mechanical specifications: 2-cell lithium-ion charging, 1.2A maximum charge current, 8.4V battery voltage, 10V maximum supply voltage, -40°C to 70°C operating range, and 20-PowerTSSOP package format. The difference is packaging format (Cut Tape/Digi-Reel vs. Tape & Reel) and product status (active vs. discontinued).

Q: What is the difference between BQ24004PWPR and BQ24004PWPRG4?

A: Both parts share identical electrical and mechanical parameters. The primary difference is product status: BQ24004PWPRG4 is discontinued at DiGi Electronics, while BQ24004PWPR is obsolete. Both are functionally equivalent for 2-cell lithium-ion charging applications.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Cut Tape, Digi-Reel, or Tape & Reel) affects only handling, storage, and assembly logistics. Electrical and thermal performance remain identical across all substitute parts.

Q: Are all substitutes ROHS3 compliant?

A: Yes. BQ24004PWPRG4, BQ24004PWPR, BQ24005PWPR, and BQ24006PWPR all carry ROHS3 compliance certification with MSL 2 (1 Year) moisture sensitivity rating.

Q: Which substitute has the best inventory availability?

A: BQ24005PWPR has the highest inventory with 5914 units in stock, followed by BQ24006PWPR with 859 units and BQ24004PWPR with 827 units.
