BQ79606APHPRQ1 Equivalent & Substitute Parts

Part Overview

The BQ79606APHPRQ1 is an automotive-grade battery monitor IC designed for lithium-ion battery packs with 3 to 6 cells. This device provides comprehensive battery management functionality including cell voltage monitoring, temperature supervision, and fault detection with over-temperature and over/under-voltage protection. The part operates across the automotive temperature range of -40°C to 105°C and meets AEC-Q100 qualification standards. With active product status and full RoHS3 compliance, this component is suitable for production deployment in automotive battery management systems requiring functional safety (FuSa) certification.

Substitute parts are identified when packaging configuration differs while all critical electrical and mechanical parameters remain identical, enabling flexibility in procurement and supply chain management.

Substitute Part Grouping Explanation

The BQ79606APHPRQ1 and BQ79606APHPTQ1 are parametric equivalents differentiated solely by packaging configuration. Both parts share identical electrical specifications, functional capabilities, and physical package dimensions (48-HTQFP 7x7). The substitution is valid based on the following matching parameters:

• Function: Battery Monitor (identical)
• Battery Chemistry: Lithium Ion (identical)
• Cell Count: 3 ~ 6 (identical)
• Fault Protection: Over Temperature, Over/Under Voltage (identical)
• Interface: SPI, UART (identical)
• Operating Temperature: -40°C ~ 105°C (identical)
• Grade: Automotive (identical)
• Qualification: AEC-Q100 (identical)
• Package / Case: 48-PowerTQFP (identical)
• Mounting Type: Surface Mount (identical)
• RoHS Status: ROHS3 Compliant (identical)
• MSL: 3 (168 Hours) (identical)

The only difference is the packaging format: BQ79606APHPRQ1 is supplied in Cut Tape (CT) & Digi-Reel®, while BQ79606APHPTQ1 is supplied in Tape & Reel (TR). This distinction affects procurement and handling but does not impact electrical performance or mechanical compatibility on the PCB.

Parameter Comparison

Engineering Selection Recommendations

Both BQ79606APHPRQ1 and BQ79606APHPTQ1 are active, production-qualified components suitable for automotive battery management applications. Selection between these parts should be based on procurement and assembly requirements:

• BQ79606APHPRQ1 (Cut Tape & Digi-Reel®) is appropriate for lower-volume production runs or applications requiring manual component handling and placement flexibility.
• BQ79606APHPTQ1 (Tape & Reel) is optimized for high-volume automated assembly processes where continuous reel feeding into pick-and-place equipment is standard.

Both parts maintain identical electrical performance, thermal characteristics, and compliance certifications. The choice between them does not affect circuit design, PCB layout, or functional validation. AEC-Q100 qualification and RoHS3 compliance are maintained across both packaging options, ensuring regulatory and quality standards are met regardless of which variant is selected.

Frequently Asked Questions (FAQ)

Q: Can BQ79606APHPTQ1 be used as a direct replacement for BQ79606APHPRQ1 in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape vs. Tape & Reel). No circuit design changes, PCB modifications, or functional re-validation are required.

Q: Does the packaging format affect the component's performance or reliability?

A: No. Packaging format is a supply chain and assembly consideration only. Electrical specifications, operating temperature range, fault protection capabilities, and reliability characteristics are identical between both variants.

Q: Are both parts AEC-Q100 qualified?

A: Yes. Both BQ79606APHPRQ1 and BQ79606APHPTQ1 carry AEC-Q100 qualification and are suitable for automotive applications requiring functional safety compliance.

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

A: Cut Tape & Digi-Reel® packaging is supplied in shorter tape segments on plastic reels, suitable for manual or semi-automated assembly. Tape & Reel (TR) packaging is supplied in continuous reels optimized for fully automated pick-and-place equipment in high-volume manufacturing.

Q: Can I mix BQ79606APHPRQ1 and BQ79606APHPTQ1 in the same production batch?

A: Yes. Both parts are functionally identical and can be used interchangeably on the same PCB assembly without any impact on performance, reliability, or compliance.

Q: Are there any moisture sensitivity or storage differences between the two packaging formats?

A: No. Both variants have identical Moisture Sensitivity Level (MSL) rating of 3 (168 Hours). Storage and handling requirements are the same.
