BQ2002FPN Equivalent & Substitute Parts

Part Overview

The BQ2002FPN is a multi-chemistry battery charger IC manufactured by Texas Instruments, designed for charging applications requiring constant and pulsed current control with programmable voltage features. The device operates across a 2V battery pack voltage range with a maximum supply voltage of 6V and supports operating temperatures from 0°C to 70°C.

The BQ2002FPN is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance of systems utilizing this charger IC.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the BQ2002FPN is determined by strict adherence to the following electrical and mechanical parameters:

• Base product number: BQ2002
• Battery chemistry support: Multi-Chemistry
• Charging current modes: Constant, Pulsed
• Programmable features: Voltage
• Battery pack voltage: 2V
• Maximum supply voltage: 6V
• Operating temperature range: 0°C ~ 70°C (TA)
• RoHS and REACH compliance status
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts are grouped into two categories:

1. Parametric Equivalent (BQ2002GPN): Maintains identical electrical specifications and through-hole mounting, differing only in packaging format (Tube vs. standard packaging).

2. Manufacturer Recommended (BQ2002FSN): Maintains identical electrical specifications but employs surface-mount technology (8-SOIC package) instead of through-hole mounting, with active product status.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the BQ2002FPN, the following selection criteria apply:

BQ2002GPN is suitable for direct replacement in through-hole PCB designs where the original 8-DIP package footprint is maintained. Both parts share identical electrical specifications and compliance certifications. The primary distinction is packaging format (Tube).

BQ2002FSN is the manufacturer-recommended substitute and is the only part with active product status. This surface-mount variant (8-SOIC package) requires PCB redesign to accommodate the different footprint and mounting technology. The electrical specifications remain identical to the original part, and full ROHS3 and REACH compliance is maintained. Active product status ensures ongoing availability and manufacturing support.

Selection between BQ2002GPN and BQ2002FSN depends on PCB design constraints: through-hole designs should utilize BQ2002GPN, while new designs or redesigns should prioritize BQ2002FSN due to its active status and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can BQ2002GPN be used as a direct replacement for BQ2002FPN?

A: Yes. BQ2002GPN maintains identical electrical specifications, operating parameters, and compliance certifications. Both use the 8-DIP through-hole package. The parts are electrically and functionally equivalent.

Q: What is the primary difference between BQ2002FPN and BQ2002FSN?

A: The primary difference is the package type and mounting technology. BQ2002FPN uses 8-DIP through-hole mounting, while BQ2002FSN uses 8-SOIC surface-mount technology. Electrical specifications are identical. BQ2002FSN has active product status, whereas BQ2002FPN is obsolete.

Q: Does BQ2002FSN require PCB redesign?

A: Yes. The 8-SOIC surface-mount package has a different footprint than the 8-DIP through-hole package. PCB layout modifications are necessary to accommodate the new package geometry and mounting method.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. BQ2002FPN, BQ2002GPN, and BQ2002FSN are all ROHS3 Compliant and REACH Unaffected.

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

A: BQ2002FSN is recommended for new designs due to its active product status, ensuring long-term availability and manufacturing support. Surface-mount technology is standard in modern PCB design practices.

Q: What is the moisture sensitivity level for all substitute parts?

A: All three parts have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
