BQ2201SN Equivalent & Substitute Parts

Part Overview

The BQ2201SN is a nonvolatile SRAM controller integrated circuit manufactured by Texas Instruments, designed for memory management applications requiring surface mount installation in 8-SOIC packaging. The device operates within a 4.5V to 5.5V supply voltage range and supports operating temperatures from 0°C to 70°C. The BQ2201SN is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the BQ2201SN is determined by the following critical parameters:

• Package / Case: Both parts must use 8-SOIC (0.154", 3.90mm Width) surface mount packaging to ensure mechanical and electrical compatibility with existing PCB layouts
• Controller Type: Both parts must function as nonvolatile SRAM controllers to maintain functional equivalence
• Voltage - Supply: Both parts must operate within the 4.5V ~ 5.5V range to ensure compatibility with existing power supply designs
• Mounting Type: Both parts must use surface mount technology for assembly compatibility

The BQ2201SN-NTR qualifies as a direct substitute based on these parameters. Both devices share identical packaging, controller functionality, voltage specifications, and mounting methodology. The primary distinction lies in product status and operating temperature range, which do not affect substitution eligibility for the specified electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

The BQ2201SN-NTR serves as the direct substitute for the obsolete BQ2201SN. Both devices maintain identical electrical specifications for supply voltage (4.5V ~ 5.5V), package configuration (8-SOIC), and controller functionality (nonvolatile SRAM). The BQ2201SN-NTR carries active product status from Texas Instruments, ensuring ongoing availability and support compared to the obsolete BQ2201SN.

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, confirming regulatory and environmental compatibility. The BQ2201SN-NTR features an extended operating temperature range (-40°C ~ 85°C) compared to the original part (0°C ~ 70°C), providing additional thermal margin for applications operating outside the original specification window.

Frequently Asked Questions (FAQ)

Q: Can the BQ2201SN-NTR directly replace the BQ2201SN on existing PCBs?

A: Yes. Both devices use identical 8-SOIC surface mount packaging with matching pinout and electrical specifications. No PCB modifications are required for substitution.

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

A: The BQ2201SN-NTR is the active production variant with extended operating temperature range (-40°C ~ 85°C) versus the original 0°C ~ 70°C specification. The BQ2201SN is classified as obsolete.

Q: Are there packaging differences between these parts?

A: No. Both parts use 8-SOIC (0.154", 3.90mm Width) surface mount packaging. The BQ2201SN-NTR is supplied in Tape & Reel format, while the BQ2201SN uses standard packaging.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the BQ2201SN and BQ2201SN-NTR are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited) and REACH unaffected status.

Q: What supply voltage range do these devices support?

A: Both devices operate within 4.5V ~ 5.5V supply voltage range, ensuring compatibility with standard 5V logic systems.
