BQ2002CPN Equivalent & Substitute Parts

Part Overview

The BQ2002CPN is a multi-chemistry battery charger IC manufactured by Texas Instruments in 8-DIP through-hole packaging. This component functions as a battery control and charging management solution supporting constant and pulsed charging modes with programmable voltage features. The BQ2002CPN carries an obsolete product status, making identification of equivalent and substitute parts essential for ongoing design support, maintenance, and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the BQ2002CPN is determined by the following core parameters: base product number (BQ2002), battery chemistry support (multi-chemistry), charging current modes (constant and pulsed), programmable voltage features, battery pack voltage (2V), maximum supply voltage (6V), operating temperature range (0°C ~ 70°C), and regulatory compliance (ROHS3, REACH Unaffected, EAR99).

Two substitute parts meet these criteria:

BQ2002CSN (MFR Recommended): Shares identical electrical specifications and base product number. Differs in mounting technology (surface mount 8-SOIC vs. through-hole 8-DIP) and product status (active vs. obsolete). Suitable for designs where PCB layout accommodates surface-mount components.

BQ2002GPN (Parametric Equivalent): Maintains identical electrical specifications, base product number, and through-hole 8-DIP packaging. Differs only in product status (obsolete). Suitable for direct pin-compatible replacement in existing through-hole designs.

Parameter Comparison

Engineering Selection Recommendations

For Through-Hole PCB Designs: BQ2002GPN provides direct pin-compatible replacement with identical electrical performance and packaging. Both BQ2002CPN and BQ2002GPN carry obsolete status; however, BQ2002GPN maintains active inventory availability (1093 pcs) compared to BQ2002CPN (33785 pcs).

For Surface-Mount PCB Designs: BQ2002CSN is the appropriate selection, offering active product status with full ROHS3 compliance and REACH unaffected certification. The 8-SOIC package requires PCB layout modification but delivers equivalent electrical functionality with modern component lifecycle support.

Compliance Considerations: All three parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory equivalence across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: Can BQ2002CSN replace BQ2002CPN in an existing design without circuit modification?

A: BQ2002CSN is electrically equivalent but requires PCB layout changes. The 8-SOIC surface-mount package differs from the 8-DIP through-hole package of BQ2002CPN. Pin-to-pin electrical functionality is identical; however, footprint redesign is necessary.

Q: Why is BQ2002CPN listed as obsolete?

A: Product status reflects Texas Instruments' lifecycle classification. Obsolete designation indicates the part is no longer in active production. Substitute parts with active status (BQ2002CSN) or equivalent obsolete status (BQ2002GPN) remain available through inventory channels.

Q: Are all three parts functionally interchangeable for multi-chemistry battery charging applications?

A: BQ2002CPN, BQ2002CSN, and BQ2002GPN share identical electrical specifications for multi-chemistry battery control, constant and pulsed charging modes, voltage programmability, 2V battery pack voltage, and 6V maximum supply voltage. Interchangeability depends on packaging compatibility with your PCB design.

Q: What is the primary difference between BQ2002CSN and BQ2002GPN?

A: BQ2002CSN uses surface-mount 8-SOIC packaging with active product status. BQ2002GPN uses through-hole 8-DIP packaging with obsolete product status. Electrical specifications are identical. Selection depends on PCB assembly technology and design requirements.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. BQ2002CPN, BQ2002CSN, and BQ2002GPN all maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory equivalence.
