Substitute Part Grouping Explanation

Substitute parts for the BQ2000TPWR are categorized based on the following substitution criteria:

Parametric Equivalent (BQ2000PWR): Identical electrical and mechanical specifications including multi-chemistry battery support, 1 to 4 cell configuration, 6V maximum supply voltage, 8-TSSOP package, and equivalent operating temperature range. Differs only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and product status (Active versus Last Time Buy).

Manufacturer Recommended Substitute (BQ25172DSGR): Supports extended cell count (1 to 6 cells), higher supply voltage (18V maximum), enhanced fault protection (Over Current, Over Temperature, Over Voltage, Short Circuit), and wider operating temperature range (-40°C to 125°C). Differs in battery chemistry specialization (Nickel Metal Hydride), package type (8-WSON 2x2), and interface capability (USB). This substitute accommodates designs requiring higher voltage rails and expanded protection features.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: BQ2000PWR is the appropriate selection when maintaining identical electrical specifications and package footprint is required. This part is in Active product status and maintains ROHS3 compliance, providing supply continuity without design modification.

For Enhanced Capability Designs: BQ25172DSGR is suitable when designs require higher supply voltage tolerance (18V maximum), extended cell count support (up to 6 cells), or enhanced fault protection mechanisms. This part is in Active product status with improved moisture sensitivity characteristics (MSL 1). Note that battery chemistry specialization (Nickel Metal Hydride) and package geometry change (8-WSON 2x2) necessitate circuit and layout evaluation.

Both substitute options are manufactured by Texas Instruments and maintain compliance certifications appropriate to their respective product classifications.

Frequently Asked Questions (FAQ)

Q: Can BQ2000PWR be used as a direct drop-in replacement for BQ2000TPWR?

A: Yes. BQ2000PWR is electrically and mechanically equivalent, with identical specifications for battery chemistry, cell count, supply voltage, operating temperature, and package dimensions. The only differences are packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and product lifecycle status (Active versus Last Time Buy).

Q: What are the key differences between BQ2000TPWR and BQ25172DSGR?

A: BQ25172DSGR supports higher supply voltage (18V versus 6V), extended cell count (1-6 versus 1-4), specialized Nickel Metal Hydride chemistry, enhanced fault protection, and wider operating temperature range. The package type differs (8-WSON 2x2 versus 8-TSSOP), requiring PCB layout changes.

Q: Is BQ25172DSGR compatible with existing BQ2000TPWR designs?

A: Compatibility depends on design requirements. If the application operates within 6V supply and 1-4 cell specifications, BQ25172DSGR's higher ratings provide margin but do not guarantee pin-for-pin compatibility. Circuit topology and PCB layout must be evaluated due to package differences.

Q: What is the significance of Last Time Buy status for BQ2000TPWR?

A: Last Time Buy indicates the manufacturer will discontinue production. New designs should transition to BQ2000PWR (parametric equivalent) or BQ25172DSGR (enhanced capability) to ensure long-term supply availability.

Q: Are there packaging considerations when substituting these parts?

A: Yes. BQ2000TPWR and BQ2000PWR use 8-TSSOP packages with identical footprints. BQ25172DSGR uses 8-WSON (2x2) package, requiring PCB redesign and revalidation of thermal and electrical performance.
