Parameter Comparison

Engineering Selection Recommendations

BQ24005PWPR is the primary recommended substitute. This part maintains Active product status with the highest inventory availability (5914 units), ensuring long-term supply continuity. It carries identical electrical specifications and ROHS3 compliance certification.

BQ24006PWPR serves as a secondary alternative with Active status and adequate inventory (859 units). This part is available in Tape & Reel packaging format, suitable for high-volume production environments.

BQ24004PWPR is not recommended for new designs due to Obsolete product status, despite matching electrical parameters and available inventory.

All substitute parts maintain ROHS3 compliance and MSL Level 2 (1 Year) moisture sensitivity ratings, meeting the same environmental and regulatory requirements as the original BQ24005PWPRG4.

Frequently Asked Questions (FAQ)

Q: Can BQ24005PWPR directly replace BQ24005PWPRG4? A: Yes. Both parts share identical electrical specifications, package dimensions (20-PowerTSSOP), and compliance certifications. The primary difference is packaging format and product status.

Q: What is the difference between BQ24005PWPR and BQ24006PWPR? A: Both parts are electrically equivalent with matching charge current (1.2A), battery voltage (8.4V), and operating temperature range (-40°C ~ 70°C). The distinction lies in packaging format: BQ24005PWPR is available in Cut Tape & Digi-Reel format, while BQ24006PWPR is supplied in Tape & Reel format.

Q: Why is BQ24004PWPR listed if it is Obsolete? A: BQ24004PWPR meets all electrical and mechanical substitution criteria. However, its Obsolete status presents supply risk for production continuity, making it unsuitable for new design implementations.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL Level 2 (1 Year) moisture sensitivity ratings, matching the original BQ24005PWPRG4 environmental specifications.

Q: Can these parts be used interchangeably in PCB assembly? A: Yes, provided the PCB footprint accommodates the 20-PowerTSSOP package dimensions (0.173" width, 4.40mm). All substitute parts use identical Surface Mount package geometry.
