BQ76PL455APFCR Equivalent & Substitute Parts

Part Overview

The BQ76PL455APFCR is a Battery Multi-Function Controller IC manufactured by Texas Instruments, designed for multi-cell lithium battery pack management in applications requiring 6 to 16 cell configurations. This device integrates over-temperature, over-voltage, and under-voltage protection with UART communication interface, housed in an 80-TQFP (12x12mm) surface mount package.

The BQ76PL455APFCR is classified as obsolete. Identifying equivalent and substitute parts is essential for design continuity, procurement planning, and system maintenance when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution of the BQ76PL455APFCR is determined by strict equivalence across the following critical parameters:

• Identical base product number (BQ76PL455)
• Matching package specification (80-TQFP, 12x12mm)
• Identical functional capability (Multi-Function Controller for 6-16 cell battery management)
• Equivalent fault protection features (Over Temperature, Over/Under Voltage)
• Matching communication interface (UART)
• Identical operating temperature range (-40°C ~ 85°C)
• Equivalent compliance certifications (ROHS3, REACH Unaffected)

The substitute part differs only in packaging format (Cut Tape versus standard packaging), which does not affect electrical or mechanical compatibility in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

The BQ76PL455APFCT is a direct functional equivalent to the BQ76PL455APFCR. Both components share identical electrical specifications, thermal characteristics, and compliance certifications. The sole distinction is the packaging format: Cut Tape (CT) versus standard packaging.

Selection between these parts should be based on procurement and assembly requirements:

• Use BQ76PL455APFCR when standard packaging format is specified or preferred for inventory management
• Use BQ76PL455APFCT when Cut Tape format aligns with automated assembly processes or supply chain availability

Both parts are classified as obsolete products. For new designs or long-term production planning, evaluation of current-generation battery management controller alternatives from Texas Instruments or other manufacturers may be warranted.

Frequently Asked Questions (FAQ)

Q: Can BQ76PL455APFCT be used as a direct replacement for BQ76PL455APFCR?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. The component itself, pin configuration, and functional performance are equivalent.

Q: What does "Cut Tape (CT)" packaging mean?

A: Cut Tape format means the components are supplied on a continuous carrier tape that has been cut into smaller sections for shipment. This differs from standard reel packaging but does not affect the component's electrical or mechanical properties.

Q: Are there any compatibility concerns when substituting between these parts?

A: No. Both parts use the same 80-TQFP (12x12mm) package with identical pin assignments, operating temperature range, and functional specifications. PCB layout and circuit design remain unchanged.

Q: Why is the BQ76PL455APFCR classified as obsolete?

A: Product status reflects Texas Instruments' lifecycle management. Obsolete designation indicates the part is no longer in active production. Existing inventory may still be available through authorized distributors.

Q: What are the critical parameters for substitution compatibility?

A: Critical parameters are: base product number (BQ76PL455), package type (80-TQFP), cell count range (6-16), protection features (Over Temperature, Over/Under Voltage), interface (UART), and operating temperature range (-40°C to 85°C).

Q: Does packaging format affect PCB assembly?

A: Packaging format affects supply chain logistics and automated pick-and-place equipment compatibility, but not PCB design or component performance. Verify your assembly equipment specifications for tape format compatibility.
