Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BQ2003PNG4 is determined by the following critical parameters:

• Package / Case: 16-DIP (0.300", 7.62mm) — ensures mechanical and electrical compatibility with existing PCB layouts
• Mounting Type: Through Hole — maintains compatibility with through-hole assembly processes
• Battery Chemistry Support: Multi-Chemistry — preserves functional capability across multiple battery types
• Charging Method: Constant-current — maintains charging profile consistency
• Programmable Features: Timer and Voltage — ensures control and protection functionality
• Voltage - Supply (Max): 5.5V — guarantees safe operation within power supply specifications
• Operating Temperature Range: 0°C ~ 70°C — maintains thermal operating envelope
• RoHS and REACH Compliance: ROHS3 Compliant, REACH Unaffected — ensures regulatory alignment

The BQ2003PN meets all these criteria and is classified as the manufacturer-recommended substitute.

Product Status: The BQ2003PN maintains active product status with Texas Instruments, ensuring ongoing availability and support, whereas the BQ2003PNG4 is discontinued.

Electrical and Mechanical Compatibility: Both parts share identical electrical specifications, package geometry, and mounting requirements. The 16-DIP through-hole package, supply voltage rating, operating temperature range, and programmable feature set are fully aligned.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for component selection.

Packaging Availability: The BQ2003PN is supplied in standard tube packaging, providing practical handling and storage advantages for production environments.

Frequently Asked Questions (FAQ)

Q: Can the BQ2003PN be used as a direct replacement for the BQ2003PNG4?

A: Yes. Both parts share identical electrical specifications, package dimensions (16-DIP, 0.300" pitch), mounting type (through-hole), and functional capabilities. No circuit modifications are required.

Q: Are there any differences in the operating temperature range?

A: No. Both the BQ2003PNG4 and BQ2003PN operate across the same temperature range of 0°C to 70°C (TA).

Q: Do both parts support the same battery chemistry types?

A: Yes. Both parts are rated for multi-chemistry battery charging with identical constant-current charging methods and programmable timer and voltage features.

Q: What is the difference in packaging between these parts?

A: The BQ2003PNG4 packaging specification was not provided in the original documentation. The BQ2003PN is supplied in tube packaging, which is standard for through-hole DIP components and provides efficient handling for production environments.

Q: Are there any compliance differences between the two parts?

A: No. Both parts maintain ROHS3 compliance and REACH unaffected status. There are no regulatory or compliance barriers to substitution.

Q: Why is the BQ2003PNG4 no longer available?

A: The BQ2003PNG4 has been discontinued at DiGi Electronics. The BQ2003PN remains in active production and is the recommended substitute for ongoing component sourcing.
