Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BQ2201SNTR is determined by the following critical parameters:

• Base Product Number Match: Both parts must share the BQ2201 base product number, ensuring identical core functionality and pinout configuration.
• Package Compatibility: Both parts must utilize the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts.
• Supply Voltage Range: Both parts must operate within the 4.5V ~ 5.5V supply voltage specification to maintain circuit performance.
• Controller Type: Both parts must function as nonvolatile SRAM controllers to preserve the intended memory management application.
• Mounting Type: Both parts must be surface mount devices to align with assembly and integration requirements.

The BQ2201SN-NTR qualifies as a direct substitute based on these parameters, with the primary distinction being its active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The BQ2201SN-NTR is the direct substitute for the BQ2201SNTR. Both components share identical electrical specifications, package geometry, and functional classification as nonvolatile SRAM controllers. The substitute part maintains full ROHS3 compliance and carries active product status, ensuring long-term availability and supply chain continuity.

The primary advantage of the BQ2201SN-NTR is its extended operating temperature range of -40°C ~ 85°C compared to the original part's 0°C ~ 70°C specification. This expanded thermal envelope provides additional operational flexibility for applications requiring wider temperature tolerance. The substitute is supplied in Tape & Reel packaging, which is standard for production-volume component procurement.

Selection of the BQ2201SN-NTR eliminates obsolescence risk while maintaining complete functional and mechanical compatibility with existing designs utilizing the BQ2201SNTR.

Frequently Asked Questions (FAQ)

Q: Can the BQ2201SN-NTR be used as a direct replacement for the BQ2201SNTR in existing designs?

A: Yes. Both parts share identical supply voltage specifications (4.5V ~ 5.5V), package geometry (8-SOIC), pinout configuration, and nonvolatile SRAM controller functionality. The substitute part is electrically and mechanically compatible with applications designed for the BQ2201SNTR.

Q: What is the difference between the BQ2201SNTR and BQ2201SN-NTR?

A: The primary differences are product status and operating temperature range. The BQ2201SNTR is obsolete with a 0°C ~ 70°C operating range, while the BQ2201SN-NTR is active with an extended -40°C ~ 85°C operating range. Both parts are ROHS3 compliant and manufactured by Texas Instruments.

Q: Does the packaging difference affect compatibility?

A: No. The packaging difference (bulk versus Tape & Reel) refers only to the delivery format and does not affect the component's electrical or mechanical performance. The actual component package remains 8-SOIC in both cases.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the BQ2201SNTR and BQ2201SN-NTR maintain identical ROHS3 compliance status, REACH unaffected classification, and EAR99 ECCN designation.

Q: Why should I select the BQ2201SN-NTR over the obsolete BQ2201SNTR?

A: The BQ2201SN-NTR is the active product offering from Texas Instruments. Selecting the active part ensures supply availability, eliminates obsolescence risk, and provides an extended operating temperature range suitable for a broader range of thermal environments.
