BQ2005STRG4 Equivalent & Substitute Parts

Part Overview

The BQ2005STRG4 is a multi-chemistry battery charger IC manufactured by Texas Instruments, designed for surface mount applications in the 20-SOIC package. This component provides constant and pulsed charging control with programmable timer and voltage features. The BQ2005STRG4 is currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing design support and production continuity. Active alternatives within the BQ2005 series maintain functional compatibility while offering improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BQ2005STRG4 is determined by strict alignment of the following electrical and mechanical parameters:

• Package Compatibility: Both parts must use the 20-SOIC (0.295", 7.50mm Width) surface mount package to ensure PCB layout and assembly compatibility
• Functional Specifications: Multi-chemistry battery charging capability with constant and pulsed charging modes
• Programmable Control: Timer and voltage programmability must be present
• Supply Voltage: Maximum supply voltage of 5.5V
• Operating Temperature Range: -20°C to 70°C (TA)
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The BQ2005STR meets all these criteria and is classified as the manufacturer-recommended substitute. Both parts share the same base product number (BQ2005) and are manufactured by Texas Instruments, ensuring design continuity.

Parameter Comparison

Engineering Selection Recommendations

The BQ2005STR is the appropriate substitute for the discontinued BQ2005STRG4. Both components are manufactured by Texas Instruments and maintain identical electrical specifications, package geometry, and compliance certifications. The BQ2005STR carries active product status with higher inventory availability (2040 Pcs), ensuring supply chain continuity. Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current production environments. The packaging difference (Tape & Reel for the substitute versus unspecified for the main part) does not affect functional compatibility and may provide logistical advantages for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the BQ2005STR be used as a direct replacement for the BQ2005STRG4?

A: Yes. Both parts share identical electrical specifications, package dimensions (20-SOIC), operating temperature range, supply voltage ratings, and functional capabilities. The BQ2005STR is the manufacturer-recommended substitute.

Q: Are there any package compatibility concerns?

A: No. Both the BQ2005STRG4 and BQ2005STR use the 20-SOIC (0.295", 7.50mm Width) surface mount package. PCB layouts and assembly processes require no modification.

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

A: The primary difference is product status. The BQ2005STRG4 is discontinued, while the BQ2005STR is active. The BQ2005STR is supplied in Tape & Reel packaging, which is standard for production quantities. All functional and electrical parameters are identical.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the BQ2005STRG4 and BQ2005STR are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: Is there any difference in charging control capabilities?

A: No. Both parts provide identical multi-chemistry battery charging with constant and pulsed current modes, programmable timer and voltage features, and -20°C to 70°C operating temperature range.

Q: What should be considered when transitioning from BQ2005STRG4 to BQ2005STR?

A: No design changes are required. The transition is a direct substitution. Verify component availability through your supplier, as the BQ2005STR has higher inventory levels (2040 Pcs) compared to the discontinued BQ2005STRG4.
