BQ2002GPN Equivalent & Substitute Parts

Part Overview

The BQ2002GPN is a multi-chemistry battery charger IC manufactured by Texas Instruments in a through-hole 8-DIP package. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs and production continuity. The BQ2002 series provides programmable voltage control for constant and pulsed charging modes across multiple battery chemistries, making substitute selection critical for maintaining circuit performance in replacement applications.

Substitute Part Grouping Explanation

Substitution of the BQ2002GPN is determined by equivalence across the following criteria:

• Base Product Number: Both parts share the BQ2002 base designation, ensuring identical functional architecture and pin configuration
• Battery Chemistry Support: Multi-chemistry capability is maintained across all substitutes
• Charging Modes: Constant and pulsed charging modes are preserved
• Voltage Programmability: Voltage control features remain consistent
• Electrical Specifications: Battery pack voltage (2V) and maximum supply voltage (6V) are identical
• Operating Temperature: 0°C to 70°C range is maintained
• Compliance Standards: ROHS3 compliance and MSL Level 1 are consistent across all parts
• Manufacturer: All substitutes are from Texas Instruments, ensuring design continuity

The primary distinction between the main part and its substitute is the package type: the BQ2002GPN uses through-hole 8-DIP mounting, while the BQ2002GSN uses surface-mount 8-SOIC packaging. This difference affects PCB layout and assembly methodology but does not alter electrical functionality or performance characteristics.

Engineering Selection Recommendations

The BQ2002GSN is the manufacturer-recommended substitute for the BQ2002GPN. Both components maintain identical electrical specifications, functional capabilities, and compliance certifications. The BQ2002GSN carries active product status from Texas Instruments, ensuring long-term availability and supply chain continuity compared to the obsolete BQ2002GPN.

Selection between these parts depends on PCB design requirements:

• BQ2002GPN (Through-Hole 8-DIP): Suitable for existing through-hole PCB designs or applications requiring through-hole mounting methodology
• BQ2002GSN (Surface-Mount 8-SOIC): Recommended for new designs, high-density PCB layouts, and automated surface-mount assembly processes

Both parts satisfy ROHS3 compliance and REACH requirements, making either suitable for regulated applications. The choice between through-hole and surface-mount packaging should be determined by PCB design architecture and manufacturing capabilities rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can the BQ2002GSN directly replace the BQ2002GPN in existing designs?

A: Electrical functionality is identical. However, direct replacement requires PCB redesign due to package differences. The BQ2002GPN uses through-hole 8-DIP mounting (0.300" spacing), while the BQ2002GSN uses surface-mount 8-SOIC packaging (0.154" width). Pin-to-pin electrical compatibility exists, but physical footprints are incompatible.

Q: Why is the BQ2002GPN listed as obsolete?

A: The BQ2002GPN is obsolete due to manufacturer discontinuation. The BQ2002GSN surface-mount variant remains in active production, reflecting industry trends toward surface-mount technology for improved manufacturing efficiency and PCB density.

Q: Are there any electrical performance differences between the BQ2002GPN and BQ2002GSN?

A: No. Both parts share identical electrical specifications, including battery chemistry support, charging modes, voltage programmability, supply voltage ratings, and operating temperature ranges. Differences are limited to package type and mounting methodology.

Q: What compliance certifications apply to both parts?

A: Both the BQ2002GPN and BQ2002GSN are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity). Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: Which part should be selected for new product designs?

A: The BQ2002GSN is recommended for new designs due to active product status, surface-mount compatibility with modern manufacturing processes, and assured long-term availability from Texas Instruments.
