Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BQ76PL102RGTR is determined by strict equivalence across the following critical parameters:

• Base Product Number: Must be BQ76PL102 to ensure identical die and firmware
• Battery Chemistry & Cell Count: Lithium Ion, 1 ~ 2 cells
• Fault Protection Capability: Under Voltage protection required
• Interface Protocol: SMBus communication standard
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Package Specification: 16-VFQFN Exposed Pad (3x3mm)
• Mounting Type: Surface Mount
• Compliance Standards: ROHS3 Compliant, REACH Unaffected

The BQ76PL102RGTT qualifies as a parametric equivalent substitute based on identical specifications across all electrical, thermal, and mechanical parameters. The difference between RGTR and RGTT designations reflects packaging reel configuration only, with no impact on component functionality or performance.

Parameter Comparison

Engineering Selection Recommendations

Both the BQ76PL102RGTR and BQ76PL102RGTT are active production components from Texas Instruments with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and lead time requirements. The BQ76PL102RGTR currently maintains higher inventory levels at 26,464 units. The BQ76PL102RGTT provides an alternative with 2,096 units in stock. Both parts are suitable for direct substitution in lithium ion battery management applications requiring 1 to 2 cell pack control with SMBus interface and under-voltage protection across the -40°C to 85°C operating range.

Frequently Asked Questions (FAQ)

Q: Can BQ76PL102RGTT be used as a direct replacement for BQ76PL102RGTR?

A: Yes. Both parts share identical electrical specifications, thermal performance, package dimensions, and compliance certifications. The suffix difference (RGTR vs. RGTT) indicates packaging reel configuration only and does not affect component functionality.

Q: What is the difference between RGTR and RGTT designations?

A: These designations reflect different tape and reel packaging configurations used during manufacturing and distribution. The electrical and mechanical specifications of the die and package remain identical.

Q: Are there any PCB layout or schematic changes required when substituting BQ76PL102RGTT for BQ76PL102RGTR?

A: No. Both parts use the 16-VFQFN (3x3mm) package with exposed pad and identical pinout. PCB layouts and schematics require no modification.

Q: Do both parts support the same battery chemistry and cell count?

A: Yes. Both the BQ76PL102RGTR and BQ76PL102RGTT are designed for Lithium Ion battery packs with 1 to 2 cell configurations and provide identical under-voltage fault protection.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 85°C (TA), suitable for industrial and automotive applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the BQ76PL102RGTR and BQ76PL102RGTT are ROHS3 compliant and REACH unaffected.
