BQ2000PWG4 Equivalent & Substitute Parts

Part Overview

The BQ2000PWG4 is a multi-chemistry battery charger IC manufactured by Texas Instruments, designed for charging 1 to 4 cell battery packs with programmable current, timer, and voltage control. The device is packaged in an 8-TSSOP surface mount package and operates across a temperature range of -20°C to 70°C.

The BQ2000PWG4 has been discontinued at DiGi Electronics. Equivalent substitute parts are available to maintain design continuity and ensure supply chain reliability for applications requiring multi-chemistry battery charging functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BQ2000PWG4 are qualified based on identical electrical and mechanical parameters. The substitution criteria are strictly limited to the following parameters:

• Battery Chemistry: Multi-Chemistry
• Number of Cells: 1 ~ 4
• Current - Charging: Constant - Programmable
• Programmable Features: Current, Timer, Voltage
• Voltage - Supply (Max): 6V
• Operating Temperature: -20°C ~ 70°C (TA)
• Mounting Type: Surface Mount
• Package / Case: 8-TSSOP (0.173", 4.40mm Width)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 2 (1 Year)

All substitute parts listed below meet these criteria and share the same base product number (BQ2000) with identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the BQ2000PWG4, the BQ2000PW is the primary substitute. This part maintains active product status with Texas Instruments and offers the highest inventory availability (2259 units), ensuring reliable supply chain access.

The BQ2000TPW is a parametric equivalent with identical electrical and mechanical specifications. However, this part carries a Last Time Buy status, indicating limited future availability. Selection of BQ2000TPW should be considered only when BQ2000PW supply is constrained or when existing inventory reserves are required.

Both substitute parts are ROHS3 compliant and maintain the same moisture sensitivity level as the original BQ2000PWG4, ensuring compatibility with existing manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can BQ2000PW and BQ2000TPW be used interchangeably with BQ2000PWG4?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, programmable features, operating temperature range, and 8-TSSOP package configuration. They are direct functional replacements.

Q: What is the difference between BQ2000PW and BQ2000TPW?

A: The primary difference is product status. BQ2000PW is an active product with ongoing manufacturing support, while BQ2000TPW is in Last Time Buy status. Both parts meet identical electrical and mechanical specifications. Selection should prioritize BQ2000PW for new designs and long-term supply assurance.

Q: Are there packaging differences between these parts?

A: Both substitute parts are supplied in Tube packaging, while the original BQ2000PWG4 packaging specification was not provided. All three parts use the same 8-TSSOP (0.173", 4.40mm Width) case. Tube packaging is standard for surface mount components and does not affect electrical performance or PCB assembly compatibility.

Q: Do these parts require any circuit design modifications?

A: No. All substitute parts share identical electrical specifications, including multi-chemistry battery support, 1-4 cell configuration, programmable current/timer/voltage control, and 6V maximum supply voltage. No circuit modifications are required.

Q: Are compliance certifications identical across all three parts?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 2, 1 Year) and ECCN/HTSUS classifications.
