Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BQ2000TPW is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: Texas Instruments
• Battery Chemistry: Multi-Chemistry capability
• Number of Cells: 1 ~ 4 cell support
• Programmable Features: Current, Timer, Voltage control
• Voltage - Supply (Max): 6V maximum input
• Package / Case: 8-TSSOP form factor
• Mounting Type: Surface Mount

Identified Substitutes:

BQ2000PW meets all primary compatibility criteria. This part is functionally identical to the BQ2000TPW, sharing the same base product number (BQ2000), battery chemistry support, cell count range, programmable features, supply voltage specification, and 8-TSSOP package. The primary distinction is product status: BQ2000PW is Active, whereas BQ2000TPW is Last Time Buy.

BQ25172DSGR is a partial substitute with significant parameter deviations. While manufactured by Texas Instruments and supporting programmable current, timer, and voltage control, this device operates at a maximum supply voltage of 18V (three times higher than BQ2000TPW), supports 1 to 6 cells (exceeding the 1 to 4 cell specification), and is packaged in 8-WSON (2x2) rather than 8-TSSOP. Battery chemistry is limited to Nickel Metal Hydride. These differences restrict substitution to applications where the higher voltage rating and expanded cell count do not create design conflicts.

Parameter Comparison

Engineering Selection Recommendations

BQ2000PW is the primary recommended substitute for BQ2000TPW. Both parts are ROHS3 compliant, share identical electrical specifications, and maintain the same 8-TSSOP package footprint. BQ2000PW carries Active product status, ensuring continued availability and support. This substitution requires no design modifications and is suitable for direct replacement in existing applications.

BQ25172DSGR is suitable only for applications where design parameters accommodate the following deviations: maximum supply voltage of 18V, support for 1 to 6 cells, Nickel Metal Hydride chemistry limitation, and 8-WSON (2x2) package form factor. This part does not carry ROHS3 compliance designation. PCB layout modifications are required due to package geometry differences. BQ25172DSGR is recommended only when application requirements align with its expanded electrical specifications and the design can accommodate package changes.

Frequently Asked Questions (FAQ)

Q: Can BQ2000PW be used as a direct replacement for BQ2000TPW?

A: Yes. BQ2000PW is functionally and electrically identical to BQ2000TPW. Both parts support multi-chemistry battery charging for 1 to 4 cells, operate at 6V maximum supply voltage, and use the 8-TSSOP package. No design changes are required.

Q: What are the limitations of using BQ25172DSGR as a substitute?

A: BQ25172DSGR operates at 18V maximum supply voltage (compared to 6V for BQ2000TPW), supports 1 to 6 cells instead of 1 to 4, and is limited to Nickel Metal Hydride chemistry. The package is 8-WSON (2x2) rather than 8-TSSOP, requiring PCB layout modifications. RoHS3 compliance is not applicable for this part.

Q: Are there package compatibility concerns when substituting BQ25172DSGR?

A: Yes. BQ25172DSGR uses 8-WSON (2x2) packaging, which differs from the 8-TSSOP package of BQ2000TPW. PCB footprint redesign is necessary. Pin assignments and thermal characteristics may also differ, requiring circuit schematic review.

Q: What is the inventory status of these substitute parts?

A: BQ2000PW has 2259 pieces in stock. BQ25172DSGR has 39708 pieces in stock. Both are available as new original components.

Q: Does BQ25172DSGR support multi-chemistry charging like BQ2000TPW?

A: No. BQ25172DSGR is limited to Nickel Metal Hydride chemistry, whereas BQ2000TPW supports multi-chemistry applications. This represents a functional limitation for applications requiring support for multiple battery types.
