Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BQ2201SNG4 is determined by the following critical parameters:

• Base Product Number: Both parts must share the BQ2201 base designation, confirming functional equivalence at the core controller level
• Package / Case: Identical 8-SOIC (0.154", 3.90mm Width) package ensures mechanical and electrical pin compatibility
• Voltage Supply Range: Both parts operate within 4.5V ~ 5.5V, allowing direct circuit integration without power supply modifications
• Mounting Type: Surface mount configuration remains consistent across substitute parts
• RoHS and Compliance Status: ROHS3 compliance and REACH unaffected status ensure regulatory alignment

The BQ2201SN-N qualifies as a direct substitute based on these parameters. The primary distinction is product status: the BQ2201SNG4 is obsolete, while the BQ2201SN-N remains active in production.

Parameter Comparison

Engineering Selection Recommendations

The BQ2201SN-N is the qualified substitute for the obsolete BQ2201SNG4. Both parts maintain identical electrical specifications for supply voltage and package configuration, ensuring direct functional replacement in existing circuit designs.

The BQ2201SN-N offers an extended operating temperature range (-40°C ~ 85°C) compared to the BQ2201SNG4 (0°C ~ 70°C), providing broader environmental capability. This expanded range does not create incompatibility; applications operating within the original 0°C ~ 70°C window will function identically with the substitute part.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, confirming regulatory and manufacturing process compatibility. The active production status of the BQ2201SN-N ensures long-term component availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the BQ2201SN-N directly replace the BQ2201SNG4 in existing designs?

A: Yes. Both parts share identical package configuration (8-SOIC), voltage supply range (4.5V ~ 5.5V), and controller functionality. No circuit modifications are required for substitution.

Q: What is the significance of the extended operating temperature range in the BQ2201SN-N?

A: The BQ2201SN-N operates from -40°C ~ 85°C, while the BQ2201SNG4 operates from 0°C ~ 70°C. This expanded range in the substitute part does not affect compatibility with applications designed for the original temperature window. The substitute part will function within the original specifications and beyond.

Q: Are there packaging differences between these parts?

A: No. Both the BQ2201SNG4 and BQ2201SN-N use identical 8-SOIC (0.154", 3.90mm Width) surface mount packages. PCB footprints and assembly processes remain unchanged.

Q: Why is the BQ2201SNG4 listed as obsolete?

A: Obsolete status indicates the part has been discontinued by Texas Instruments. The BQ2201SN-N represents the active production equivalent, ensuring continued availability for new designs and production requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited), confirming equivalent regulatory and manufacturing compliance.
