Substitute Part Grouping Explanation

Substitution of the BQ2002SNTRG4 is determined by strict equivalence across the following critical parameters:

• Manufacturer: Texas Instruments (same manufacturer ensures design compatibility)
• Base Product Number: BQ2002 (identical functional core)
• Package / Case: 8-SOIC (0.154", 3.90mm Width) (identical pinout and footprint)
• Battery Chemistry Support: Multi-Chemistry (identical application scope)
• Charging Current Type: Constant, Pulsed (identical charging modes)
• Programmable Features: Voltage (identical control capability)
• Battery Pack Voltage: 2V (identical voltage rating)
• Supply Voltage (Max): 6V (identical supply requirements)
• Operating Temperature Range: 0°C ~ 70°C (TA) (identical thermal specification)
• RoHS Status: ROHS3 Compliant (identical environmental compliance)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (identical moisture handling)

All substitute parts maintain identical electrical and mechanical specifications, ensuring direct functional replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

BQ2002CSNTR is the primary substitute for the discontinued BQ2002SNTRG4. This part maintains active product status with Texas Instruments and carries 2,838 units in current inventory. All electrical and mechanical parameters are identical to the original part, ensuring direct replacement without circuit modification. ROHS3 compliance and MSL rating are maintained.

BQ2002TSNTR is an alternative substitute available in Tape & Reel (TR) packaging format. This variant is suitable for high-volume production environments requiring automated component handling. With 22,900 units in inventory, this part offers superior availability. Electrical specifications and compliance certifications are identical to the BQ2002SNTRG4. The only distinction is the packaging format; circuit-level performance remains unchanged.

Both substitute parts are manufactured by Texas Instruments under the same BQ2002 base product number and are fully compliant with ROHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can BQ2002CSNTR and BQ2002TSNTR be used interchangeably with BQ2002SNTRG4?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, package dimensions, and functional capabilities. The only difference is packaging format: BQ2002CSNTR uses standard packaging, while BQ2002TSNTR uses Tape & Reel format for automated assembly.

Q: What is the difference between standard packaging and Tape & Reel (TR) packaging?

A: Tape & Reel packaging is designed for high-speed automated pick-and-place assembly equipment. Standard packaging is suitable for manual or lower-volume assembly processes. The component itself and its electrical performance are identical.

Q: Are all three parts ROHS3 compliant?

A: Yes. BQ2002SNTRG4, BQ2002CSNTR, and BQ2002TSNTR are all ROHS3 compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Why is BQ2002SNTRG4 discontinued?

A: Product discontinuation at DiGi Electronics does not indicate a design flaw. BQ2002CSNTR and BQ2002TSNTR remain active products from Texas Instruments and provide identical functionality for new designs and production continuity.

Q: Which substitute should I select for new production?

A: For standard assembly processes, use BQ2002CSNTR. For automated high-volume production, use BQ2002TSNTR. Both are functionally equivalent to the original BQ2002SNTRG4.
