Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BQ24007RGWR is determined by the following critical parameters:

Primary Compatibility Criteria:

• Battery chemistry (Lithium Ion or Lithium Ion/Polymer)
• Single-cell charging capability
• Maximum charge current rating (≥1.2A)
• Battery pack voltage (4.2V)
• Maximum supply voltage (≥10V)
• Operating temperature range (must encompass -40°C ~ 70°C minimum)
• Surface-mount packaging with exposed pad
• RoHS3 compliance

Substitute Parts Identified:

1. BQ24040DSQR - Manufacturer-recommended substitute. Supports Lithium Ion/Polymer chemistry with enhanced fault protection (over-voltage and short-circuit). Operates at higher maximum supply voltage (28V) and extended temperature range (-40°C ~ 85°C). Packaged in 10-WSON (2x2) with active product status.

2. BQ24002RGWR - Parametric equivalent. Maintains identical package (20-VQFN), charge current (1.2A), battery voltage (4.2V), and supply voltage (10V) specifications. Active product status with equivalent thermal and compliance ratings.

Parameter Comparison

Engineering Selection Recommendations

BQ24002RGWR is the direct parametric equivalent for applications requiring pin-compatible replacement. It maintains identical electrical specifications, package footprint, and thermal characteristics while offering active product status and current manufacturing availability (1835 Pcs in stock).

BQ24040DSQR is the manufacturer-recommended alternative for new designs or applications where design modification is acceptable. This part offers enhanced fault protection capabilities (over-voltage and short-circuit detection), extended operating temperature range, and higher maximum supply voltage tolerance. The 10-WSON package requires PCB layout redesign. Current inventory availability is significantly higher (65400 Pcs in stock).

Both substitute parts maintain ROHS3 compliance and equivalent moisture sensitivity ratings. Selection depends on design constraints: choose BQ24002RGWR for direct replacement; choose BQ24040DSQR for new designs with enhanced protection requirements.

Frequently Asked Questions (FAQ)

Q: Can BQ24040DSQR be used as a direct pin-for-pin replacement?

A: No. BQ24040DSQR uses a 10-WSON (2x2) package versus the BQ24007RGWR's 20-VQFN (5x5) package. PCB layout and schematic modifications are required. BQ24002RGWR provides pin-compatible replacement capability.

Q: What is the key difference between BQ24040DSQR and BQ24002RGWR?

A: BQ24040DSQR offers enhanced fault protection (over-voltage and short-circuit detection) and higher maximum supply voltage (28V vs 10V), but requires package redesign. BQ24002RGWR maintains identical specifications and package, requiring no design changes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. BQ24007RGWR, BQ24040DSQR, and BQ24002RGWR are all ROHS3 compliant with MSL rating 2 (1 Year).

Q: Which substitute part has better availability?

A: BQ24040DSQR has the highest current inventory (65400 Pcs). BQ24002RGWR has 1835 Pcs available. BQ24007RGWR (obsolete) has 2786 Pcs remaining stock.

Q: Can BQ24040DSQR charge at 1.2A like the original part?

A: BQ24040DSQR has a maximum charge current rating of 1A, which is 0.2A lower than the BQ24007RGWR's 1.2A rating. Applications requiring 1.2A charging current must use BQ24002RGWR.

Q: What is the operating temperature difference between substitutes?

A: BQ24007RGWR and BQ24002RGWR operate from -40°C to 70°C. BQ24040DSQR extends the upper limit to 85°C, providing 15°C additional thermal margin.
