Key Parameters

Substitute Part Grouping Explanation

Substitution of the BQ2201PN is determined by the following critical parameters:

• Functional Equivalence: Controller type must be nonvolatile SRAM
• Electrical Compatibility: Supply voltage range must support 4.5V ~ 5.5V operation
• Base Product Number: BQ2201 series maintains functional compatibility
• Compliance Requirements: RoHS3 compliance and REACH unaffected status must be maintained

The identified substitute part BQ2201SN-N shares the same base product number and functional classification, ensuring equivalent nonvolatile SRAM controller operation. Both parts are manufactured by Texas Instruments and maintain identical compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The BQ2201SN-N is the manufacturer-recommended substitute for the obsolete BQ2201PN. Both parts maintain identical electrical specifications for supply voltage and controller functionality. The BQ2201SN-N offers extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and active product status, ensuring long-term availability and supply chain continuity.

Selection of the BQ2201SN-N requires accommodation of package and mounting type differences. The transition from through-hole 8-DIP to surface-mount 8-SOIC packaging necessitates PCB layout and assembly process modifications. Both parts maintain equivalent RoHS3 compliance and moisture sensitivity classifications, ensuring regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can the BQ2201SN-N directly replace the BQ2201PN without circuit modifications?

A: Electrical functionality is equivalent; however, the package change from 8-DIP to 8-SOIC requires PCB redesign and assembly process adaptation. Pin configuration remains consistent within the BQ2201 series.

Q: What is the primary reason for substitution?

A: The BQ2201PN is classified as obsolete. The BQ2201SN-N is the active equivalent part, ensuring continued availability and supply chain support.

Q: Are there compliance differences between these parts?

A: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity levels. No compliance degradation occurs with substitution.

Q: How do the operating temperature ranges differ?

A: The BQ2201SN-N supports -40°C to 85°C, compared to the BQ2201PN range of 0°C to 70°C. The substitute provides extended low-temperature operation and higher maximum temperature capability.

Q: What mounting considerations apply to the BQ2201SN-N?

A: The BQ2201SN-N is surface-mount technology (SMT) in 8-SOIC package, whereas the BQ2201PN uses through-hole 8-DIP mounting. Assembly equipment and PCB footprint design must be updated accordingly.
