BQ2002TPN Equivalent & Substitute Parts

Part Overview

The BQ2002TPN is a multi-chemistry battery charger IC manufactured by Texas Instruments, housed in an 8-DIP through-hole package. This component is classified as obsolete, indicating it is no longer in active production. The BQ2002TPN provides constant and pulsed charging current control with programmable voltage features, supporting battery pack voltages up to 2V and supply voltages up to 6V. Due to its obsolete status, equivalent substitute parts are necessary for new designs or when inventory becomes unavailable.

The BQ2002TPN has two identified substitutes: BQ2002GPN (parametric equivalent with identical through-hole DIP packaging) and BQ2002TSN (manufacturer-recommended equivalent with surface-mount SOIC packaging). Both maintain identical electrical specifications and compliance certifications while differing in package form factor and product status.

Parameter Comparison

Engineering Selection Recommendations

BQ2002GPN (Parametric Equivalent): This part maintains identical electrical specifications and through-hole DIP packaging as the BQ2002TPN. Both parts share obsolete product status. Selection of BQ2002GPN is appropriate for direct replacement in existing through-hole PCB designs where pin-for-pin compatibility is required. Current inventory availability is 1093 pieces.

BQ2002TSN (Manufacturer-Recommended Equivalent): This part provides identical electrical functionality with ROHS3 compliance and REACH unaffected status. The primary distinction is the surface-mount 8-SOIC package form factor and active product status. BQ2002TSN is the preferred long-term solution for new designs or redesigns incorporating surface-mount assembly processes. Current inventory availability is 2399 pieces.

Both substitute parts maintain full compliance with ROHS3 and REACH requirements, ensuring regulatory alignment with the original BQ2002TPN specification.

Frequently Asked Questions (FAQ)

Q: Can BQ2002TSN replace BQ2002TPN in an existing through-hole design? A: BQ2002TSN uses an 8-SOIC surface-mount package, while BQ2002TPN uses an 8-DIP through-hole package. Direct PCB substitution is not possible without redesign. For through-hole designs, BQ2002GPN is the appropriate substitute.

Q: What is the difference between BQ2002GPN and BQ2002TSN? A: Both parts share identical electrical specifications and compliance certifications. BQ2002GPN maintains the through-hole 8-DIP package and obsolete status. BQ2002TSN uses a surface-mount 8-SOIC package and has active product status, making it suitable for new designs.

Q: Are all three parts electrically interchangeable? A: Yes. BQ2002TPN, BQ2002GPN, and BQ2002TSN all provide identical multi-chemistry battery charging functionality with constant and pulsed current modes, programmable voltage control, 2V battery pack voltage support, and 6V maximum supply voltage operation across the 0°C to 70°C temperature range.

Q: Which substitute should be selected for new product development? A: BQ2002TSN is recommended for new designs due to its active product status and surface-mount package compatibility with modern manufacturing processes.

Q: Are moisture sensitivity and compliance certifications identical across all three parts? A: Yes. All three parts maintain MSL 1 (Unlimited), ROHS3 compliance, and REACH unaffected status.
