Key Parameters

Substitute Part Grouping Explanation

Substitution for the BQ2002CSNTRG4 is determined by strict equivalence across the following parameters:

• Base product number (BQ2002)
• Battery chemistry support (Multi-Chemistry)
• Battery pack voltage (2V)
• Maximum supply voltage (6V)
• Charging current modes (Constant, Pulsed)
• Programmable voltage features
• Operating temperature range (0°C ~ 70°C)
• Package type (8-SOIC with 0.154" width, 3.90mm)
• Surface mount mounting type
• Compliance certifications (ROHS3, REACH Unaffected)

The substitute parts BQ2002CSNTR and BQ2002TSNTR meet all these criteria and are direct functional equivalents. The primary differences are product status (Active vs. Discontinued) and packaging format (Tube vs. Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

Both BQ2002CSNTR and BQ2002TSNTR are direct substitutes for the discontinued BQ2002CSNTRG4. Selection between them depends on procurement and assembly requirements:

BQ2002CSNTR is supplied in tube packaging and maintains Active product status with higher inventory availability than the original part. This option is suitable for standard component procurement workflows.

BQ2002TSNTR is supplied in Tape & Reel format and is optimized for automated assembly processes. This variant offers the highest inventory availability (22900 Pcs) and is recommended for high-volume production environments.

Both parts carry identical ROHS3 compliance and REACH Unaffected status, ensuring regulatory compliance in all applications. The electrical and mechanical specifications are fully equivalent across all three part numbers.

Frequently Asked Questions (FAQ)

Q: Can BQ2002CSNTR and BQ2002TSNTR be used interchangeably with BQ2002CSNTRG4?

A: Yes. Both substitute parts are parametric equivalents with identical electrical specifications, operating ranges, and 8-SOIC package dimensions. The only differences are product status (Active vs. Discontinued) and packaging format (Tube vs. Tape & Reel).

Q: What is the difference between tube and Tape & Reel packaging?

A: Tube packaging is used for manual or semi-automated assembly. Tape & Reel packaging is designed for fully automated pick-and-place assembly equipment. Both formats contain the same component with identical electrical performance.

Q: Are there any compliance differences between the three part numbers?

A: No. All three parts are ROHS3 Compliant, REACH Unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory compliance is equivalent across all variants.

Q: Which substitute should I select for new designs?

A: For new designs, either BQ2002CSNTR or BQ2002TSNTR is appropriate. Choose BQ2002TSNTR if your manufacturing process uses automated assembly; choose BQ2002CSNTR for manual or semi-automated assembly workflows.

Q: Are the pin configurations identical across all three parts?

A: Yes. All three parts use the 8-SOIC package with 0.154" width and 3.90mm height. Pin configuration and PCB footprint are identical.
