Substitute Part Grouping Explanation

Substitution eligibility for the BQ2002PNG4 is determined by strict equivalence across the following critical parameters:

• Battery Chemistry: Multi-Chemistry
• Current - Charging Mode: Constant, Pulsed
• Programmable Features: Voltage
• Battery Pack Voltage: 2V
• Voltage - Supply (Max): 6V
• Operating Temperature Range: 0°C ~ 70°C (TA)
• Mounting Type: Through Hole
• Package / Case: 8-DIP (0.300", 7.62mm)
• Supplier Device Package: 8-PDIP
• Base Product Number: BQ2002

The BQ2002GPN qualifies as a parametric equivalent substitute, sharing identical electrical specifications and package configuration. Packaging format differs (Tube versus unspecified for the main part), but this does not affect functional compatibility or pin-level integration.

Parameter Comparison

Engineering Selection Recommendations

The BQ2002GPN is a direct parametric equivalent to the BQ2002PNG4 for applications requiring multi-chemistry battery charging with constant and pulsed current control. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing environments. The identical electrical specifications, operating temperature range, and 8-DIP package footprint ensure pin-compatible integration without circuit modification.

Packaging format represents the only non-functional difference; the BQ2002GPN is supplied in Tube format, which does not affect electrical performance or board-level compatibility. Component selection should prioritize availability and supply chain continuity, as both parts share obsolete product status.

Frequently Asked Questions (FAQ)

Q: Can BQ2002GPN be used as a direct replacement for BQ2002PNG4 in existing designs?

A: Yes. The BQ2002GPN is a parametric equivalent with identical electrical specifications, operating temperature range, and 8-DIP package configuration. No circuit modifications are required for substitution.

Q: What is the significance of the packaging format difference (Tube vs. unspecified)?

A: Packaging format affects handling, storage, and automated assembly processes but does not impact electrical performance or pin compatibility. Tube packaging is standard for component distribution and does not restrict functional integration.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both BQ2002PNG4 and BQ2002GPN are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for manufacturing and distribution in current markets.

Q: Why is product status listed as obsolete for both parts?

A: Obsolete status indicates that Texas Instruments has discontinued active production and support for the BQ2002 series. Existing inventory remains available through authorized distributors, but long-term availability is not guaranteed. Design reviews should evaluate modern multi-chemistry charger alternatives for new product development.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts share identical operating temperature specifications (0°C ~ 70°C) and functional parameters. Thermal behavior and performance characteristics are equivalent.
