Key Parameters

Substitute Part Grouping Explanation

Substitution of the BQ2201PNG4 is determined by the following critical parameters:

• Base product number (BQ2201) ensures functional equivalence at the controller level
• Supply voltage range (4.5V ~ 5.5V) must be maintained for circuit compatibility
• Controller type (Nonvolatile SRAM) defines the functional category
• RoHS3 compliance and REACH unaffected status ensure regulatory alignment
• Packaging format determines board integration method

The BQ2201SN-N qualifies as a manufacturer-recommended substitute based on identical base product number, matching voltage specifications, equivalent controller functionality, and consistent compliance certifications. The primary difference is the transition from through-hole (DIP) to surface-mount (SOIC) packaging, which requires PCB redesign considerations.

Parameter Comparison

Engineering Selection Recommendations

The BQ2201SN-N is the manufacturer-recommended substitute for the obsolete BQ2201PNG4. Both parts maintain identical supply voltage specifications (4.5V ~ 5.5V) and equivalent nonvolatile SRAM controller functionality. The substitute part carries active product status, ensuring long-term availability and supply chain continuity.

Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The BQ2201SN-N offers an extended operating temperature range (-40°C ~ 85°C) compared to the original part (0°C ~ 70°C), providing greater thermal flexibility for diverse application environments.

The primary design consideration is the packaging transition from through-hole DIP to surface-mount SOIC format. This change requires PCB layout modification but does not affect electrical functionality or pin configuration compatibility.

Frequently Asked Questions (FAQ)

Q: Can the BQ2201SN-N directly replace the BQ2201PNG4 without circuit modifications?

A: Electrical functionality is fully compatible. Pin configuration and voltage specifications are identical. However, the packaging format differs (DIP versus SOIC), requiring PCB redesign for physical integration.

Q: What is the primary reason for substitution?

A: The BQ2201PNG4 is classified as obsolete. The BQ2201SN-N is the active equivalent from the same manufacturer, ensuring continued availability and supply chain reliability.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: Does the operating temperature range difference affect compatibility?

A: The BQ2201SN-N supports a wider operating temperature range (-40°C ~ 85°C) compared to the original part (0°C ~ 70°C). This provides enhanced thermal capability and does not restrict compatibility in applications within the original temperature specification.

Q: What packaging considerations apply to this substitution?

A: The original part uses 8-DIP through-hole packaging (0.300", 7.62mm). The substitute uses 8-SOIC surface-mount packaging (0.154", 3.90mm Width). PCB footprint and assembly process modifications are required.
