Key Parameters

Substitute Part Grouping Explanation

Substitution for the BQ2002PN is determined by the following critical parameters:

• Base Product Number: BQ2002 (all substitutes share this base designation)
• Battery Chemistry: Multi-Chemistry (all substitutes support identical chemistry)
• Charging Control: Constant and Pulsed modes (consistent across all variants)
• Programmable Features: Voltage (maintained in all substitutes)
• Battery Pack Voltage: 2V (identical across all parts)
• Supply Voltage (Max): 6V (identical across all parts)
• Operating Temperature Range: 0°C ~ 70°C (TA) (identical across all parts)
• RoHS & Compliance: ROHS3 Compliant, REACH Unaffected (consistent across all variants)

Substitutes are categorized into two groups:

Parametric Equivalent (Same Package): BQ2002GPN maintains the 8-DIP through-hole package, providing direct pin-compatible substitution with identical electrical specifications.

Manufacturer Recommended Substitute (Different Package): BQ2002SN uses an 8-SOIC surface-mount package, offering equivalent electrical functionality with different mounting technology. This substitute requires PCB redesign for surface-mount implementation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No PCB Redesign): Select BQ2002GPN. This part maintains the 8-DIP through-hole package identical to BQ2002PN, enabling direct pin-compatible substitution. Both parts are obsolete with equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected). Electrical specifications and operating parameters are identical.

For New Designs or PCB Redesign: Select BQ2002SN. This part is active in production status, ensuring long-term availability and supply chain stability. It provides identical electrical functionality and compliance certifications while using surface-mount technology (8-SOIC package). PCB layout modification is required to accommodate the different package footprint.

Compliance Considerations: All three parts maintain ROHS3 compliance and REACH unaffected status, with MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance across substitution options.

Frequently Asked Questions (FAQ)

Q: Can BQ2002GPN be used as a direct replacement for BQ2002PN?

A: Yes. BQ2002GPN is a parametric equivalent with identical 8-DIP through-hole packaging, pin configuration, and electrical specifications. No PCB modifications are required.

Q: What is the primary difference between BQ2002GPN and BQ2002SN?

A: The primary difference is packaging technology. BQ2002GPN uses through-hole 8-DIP mounting, while BQ2002SN uses surface-mount 8-SOIC technology. Electrical functionality and specifications are identical. BQ2002SN is currently active in production, whereas BQ2002GPN is obsolete.

Q: Why is BQ2002PN listed as obsolete?

A: BQ2002PN has reached end-of-life status with Texas Instruments. Equivalent parts (BQ2002GPN and BQ2002SN) are available to support existing designs and provide forward compatibility.

Q: Are there any electrical parameter differences between the three parts?

A: No. All three parts share identical electrical specifications: multi-chemistry battery support, constant and pulsed charging modes, voltage programmability, 2V battery pack voltage, 6V maximum supply voltage, and 0°C to 70°C operating temperature range.

Q: Which substitute should be selected for new production designs?

A: BQ2002SN is recommended for new designs due to its active production status, ensuring sustained availability. Surface-mount technology also provides advantages in modern PCB assembly processes.

Q: Are compliance certifications identical across all three parts?

A: Yes. All parts maintain ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited), ensuring equivalent regulatory and environmental compliance.

Q: What PCB modifications are required when switching from BQ2002PN to BQ2002SN?

A: PCB footprint redesign is necessary. BQ2002PN uses 8-DIP through-hole footprint (0.300", 7.62mm), while BQ2002SN requires 8-SOIC surface-mount footprint (0.154", 3.90mm width). Pin assignments remain functionally equivalent.
