BQ2002FSNTR Equivalent & Substitute Parts

Part Overview

The BQ2002FSNTR is an active, production-status battery charger IC from Texas Instruments designed for multi-chemistry battery applications. This Power Management (PMIC) component operates in the 8-SOIC surface mount package and supports constant and pulsed charging modes with programmable voltage control. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard manufacturing environments.

Substitute parts become necessary when primary inventory is unavailable, when procurement lead times exceed project requirements, or when alternative packaging formats better suit assembly workflows while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BQ2002FSNTR is determined by strict parametric matching across the following criteria:

Electrical Parameters: Battery chemistry (Multi-Chemistry), charging current modes (Constant, Pulsed), programmable voltage control, battery pack voltage (2V), maximum supply voltage (6V), and operating temperature range (0°C ~ 70°C).

Mechanical Parameters: Package type (8-SOIC with 0.154" / 3.90mm width), surface mount mounting type, and supplier device package designation (8-SOIC).

Compliance & Environmental: ROHS3 compliance, MSL 1 rating, REACH unaffected status, and active product status.

Packaging Format: Tape & Reel (TR) or alternative packaging configurations that do not alter electrical or mechanical performance.

All substitute parts listed below share identical base product number (BQ2002) and meet all parametric requirements without exception.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BQ2002FSNTR, BQ2002CSNTR, and BQ2002TSNTR—are active production components from Texas Instruments with identical electrical and mechanical specifications. Selection between them is determined by packaging format availability and inventory status rather than functional differences.

BQ2002FSNTR and BQ2002TSNTR are both supplied in Tape & Reel (TR) format, suitable for automated assembly lines. BQ2002CSNTR packaging format is not specified in the provided data but maintains full parametric equivalence.

All parts carry ROHS3 compliance, REACH unaffected status, and EAR99 export classification. MSL 1 rating permits unlimited shelf life under standard storage conditions. Selection should prioritize inventory availability and lead time requirements without compromising design performance.

Frequently Asked Questions (FAQ)

Q: Are BQ2002CSNTR and BQ2002TSNTR direct drop-in replacements for BQ2002FSNTR?

A: Yes. All three parts share identical electrical specifications, package dimensions (8-SOIC, 0.154" / 3.90mm width), mounting type (surface mount), and functional capabilities. PCB layout and schematic connections require no modification.

Q: What is the difference between the three part numbers?

A: The differences are limited to packaging format and inventory status. BQ2002FSNTR and BQ2002TSNTR are supplied in Tape & Reel format. BQ2002CSNTR packaging format is not specified. All three are identical in electrical performance and mechanical fit.

Q: Can I use these parts interchangeably in production?

A: Yes, provided the packaging format suits your assembly process. Tape & Reel parts (BQ2002FSNTR, BQ2002TSNTR) are optimized for automated pick-and-place equipment. Verify packaging compatibility with your manufacturing workflow before procurement.

Q: Are there any compliance or environmental differences?

A: No. All three parts are ROHS3 compliant, REACH unaffected, carry MSL 1 rating, and hold EAR99 export classification. Compliance status is identical across all variants.

Q: What inventory levels are available?

A: BQ2002FSNTR: 55,224 pcs. BQ2002CSNTR: 2,838 pcs. BQ2002TSNTR: 22,900 pcs. Inventory status may change; verify current availability with your supplier.

Q: Do these parts support the same battery chemistries and charging modes?

A: Yes. All three support multi-chemistry battery applications with constant and pulsed charging modes. Voltage programmability is identical across all variants.
