BQ26220PWG4 Equivalent & Substitute Parts

Part Overview

The BQ26220PWG4 is a Battery Monitor IC for single-cell lithium-ion applications, manufactured by Texas Instruments in an 8-TSSOP surface mount package. This device communicates via the HDQ interface and operates across the temperature range of -20°C to 70°C. The BQ26220PWG4 is currently discontinued at DiGi Electronics, making identification of equivalent and substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the BQ26220PWG4 is determined by strict equivalence across the following critical parameters:

• Battery Chemistry: Lithium Ion
• Number of Cells: 1
• Interface: HDQ
• Operating Temperature Range: -20°C ~ 70°C (TA)
• Package / Case: 8-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 2 (1 Year)

Two substitute parts meet these criteria: BQ26220PW (MFR Recommended) and BQ26221PW (Parametric Equivalent). Both are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications to the discontinued BQ26220PWG4.

Parameter Comparison

Engineering Selection Recommendations

BQ26220PW is the primary substitute for the discontinued BQ26220PWG4. Both parts share identical electrical and mechanical specifications, with BQ26220PW currently in active production status and available in tube packaging. This part maintains full compatibility with existing designs and certifications.

BQ26221PW serves as a parametric equivalent, offering identical functional and environmental specifications. As an active product with confirmed inventory, BQ26221PW provides an alternative source for single-cell lithium-ion battery monitoring applications requiring HDQ interface communication.

Both substitute parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring compatibility with existing supply chain and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can BQ26220PW directly replace BQ26220PWG4 in existing designs? A: Yes. BQ26220PW is electrically and mechanically identical to BQ26220PWG4, with matching package, interface, temperature range, and compliance certifications. No design modifications are required.

Q: What is the difference between BQ26220PW and BQ26221PW? A: Both parts are parametric equivalents with identical electrical specifications, operating temperature, package, and interface. The primary difference is the base product number (BQ26220 versus BQ26221). Both are suitable substitutes for the discontinued BQ26220PWG4.

Q: Are the substitute parts available in the same packaging as the original? A: BQ26220PWG4 packaging is not specified in the available data. Both substitute parts (BQ26220PW and BQ26221PW) are supplied in tube packaging. Verify packaging requirements for your specific application.

Q: Do the substitute parts meet the same compliance standards? A: Yes. Both BQ26220PW and BQ26221PW are ROHS3 compliant with identical moisture sensitivity levels (MSL 2, 1 Year) and REACH unaffected status, matching the original BQ26220PWG4 specifications.

Q: Which substitute should be selected for new designs? A: BQ26220PW is recommended as the primary choice due to its active product status and direct part number lineage to the original BQ26220PWG4. BQ26221PW is a valid alternative if supply constraints require it.
