Substitute Part Grouping Explanation

Substitute parts for the BQ2000SN-B5G4 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Battery Chemistry: Multi-Chemistry
• Number of Cells: 1 ~ 4
• Current - Charging: Constant - Programmable
• Programmable Features: Current, Timer, Voltage
• Voltage - Supply (Max): 6V
• Operating Temperature: -20°C ~ 70°C (TA)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

The BQ2000SN-B5G4 has two qualified substitutes: BQ2000SN-B5 and BQ2000TSN-B5. Both maintain identical electrical specifications and package requirements, with differences limited to product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

BQ2000SN-B5 is the primary substitute for the BQ2000SN-B5G4. Both parts are manufactured by Texas Instruments, maintain identical electrical and mechanical specifications, and share ROHS3 compliance and MSL 1 ratings. The BQ2000SN-B5 carries Active product status, ensuring continued availability and support. This part is supplied in Tube packaging format.

BQ2000TSN-B5 is a secondary substitute manufactured by Benchmarq. While it maintains all critical electrical parameters and the same 8-SOIC package, it carries Active product status and is supplied in Bulk packaging. Compliance certifications for this part are not fully specified in available documentation.

For new designs and production continuity, BQ2000SN-B5 is the recommended substitute due to Texas Instruments manufacturing origin and complete compliance documentation alignment with the original BQ2000SN-B5G4.

Frequently Asked Questions (FAQ)

Q: Can BQ2000SN-B5 be used as a direct replacement for BQ2000SN-B5G4?

A: Yes. Both parts share identical electrical specifications, including multi-chemistry battery support for 1 to 4 cells, programmable charging current, timer, and voltage control. Both operate at 6V maximum supply voltage and use the 8-SOIC package. The primary difference is product status: BQ2000SN-B5G4 is obsolete while BQ2000SN-B5 is active.

Q: What is the difference between BQ2000SN-B5 and BQ2000TSN-B5?

A: Both parts meet the same electrical and package requirements. The primary differences are manufacturer (Texas Instruments vs. Benchmarq) and packaging format (Tube vs. Bulk). Compliance documentation is complete for BQ2000SN-B5 but not fully specified for BQ2000TSN-B5.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. All three parts use the identical 8-SOIC (0.154", 3.90mm Width) surface mount package. PCB layout and reflow soldering parameters remain unchanged.

Q: Does the operating temperature range remain the same across all substitutes?

A: Yes. All three parts operate across the same temperature range of -20°C to 70°C (TA).

Q: What is the inventory status for substitute parts?

A: BQ2000SN-B5 has 2336 pieces in stock (Active status). BQ2000TSN-B5 has 1279 pieces in stock (Active status). The original BQ2000SN-B5G4 has 1988 pieces in stock but is classified as obsolete.
