BQ2002SNTR Equivalent & Substitute Parts

Part Overview

The BQ2002SNTR is a multi-chemistry battery charger IC manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This 8-SOIC surface mount device provides constant and pulsed charging control with programmable voltage features for battery pack applications up to 2V. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same base product family, ensuring functional interchangeability in target applications.

Substitute Part Grouping Explanation

Substitute parts for the BQ2002SNTR are identified based on strict parametric equivalence within the BQ2002 base product family. All substitute candidates maintain identical electrical specifications including multi-chemistry battery support, constant and pulsed charging modes, voltage programmability, 2V battery pack voltage rating, and 6V maximum supply voltage. All substitutes operate within the same 0°C to 70°C temperature range and utilize the identical 8-SOIC package footprint (0.154", 3.90mm width). Compliance certifications including RoHS3, REACH unaffected status, and MSL 1 rating are uniform across all variants. Substitution eligibility is determined solely by these matching parameters; no additional technical criteria are applied.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BQ2002SNTR, BQ2002CSNTR, and BQ2002TSNTR—are active production components from Texas Instruments with identical electrical and mechanical specifications. Selection between these variants is based on packaging and inventory availability rather than functional differences. The BQ2002SNTR and BQ2002TSNTR are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The BQ2002CSNTR does not specify packaging format in the provided data. All parts maintain full RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and consumer applications. MSL 1 rating indicates unlimited shelf life under standard storage conditions. Component selection should prioritize availability and packaging requirements for the target manufacturing process.

Frequently Asked Questions (FAQ)

Q: Are BQ2002CSNTR and BQ2002TSNTR direct substitutes for BQ2002SNTR?

A: Yes. All three parts share identical electrical parameters including multi-chemistry battery support, charging modes, voltage programmability, supply voltage ratings, and operating temperature range. They use the same 8-SOIC package footprint and maintain equivalent compliance certifications.

Q: What is the difference between these part variants?

A: The primary difference is packaging format. BQ2002SNTR and BQ2002TSNTR are supplied in Tape & Reel format for automated assembly. BQ2002CSNTR packaging format is not specified in available data. All variants are functionally equivalent.

Q: Can I use BQ2002CSNTR in place of BQ2002SNTR on a PCB?

A: Yes, provided the packaging format is compatible with your assembly process. The 8-SOIC footprint is identical across all variants, ensuring mechanical and electrical compatibility.

Q: Are there any temperature or voltage limitations I should consider?

A: All variants operate identically within 0°C to 70°C ambient temperature range and support up to 6V maximum supply voltage with 2V battery pack voltage rating. No additional limitations apply between substitutes.

Q: What is the MSL rating and why does it matter?

A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components can be stored indefinitely under standard conditions without special desiccant packaging or shelf-life constraints.

Q: Are these parts RoHS compliant?

A: Yes. All three variants are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory standards for industrial and consumer electronics applications.
