Substitute Part Grouping Explanation

Substitution of the SN75ALS172N is based on the following criteria derived from the provided parameters:

Primary Substitution Basis:

• Manufacturer alignment (Texas Instruments)
• Functional category (Interface)
• Base product number compatibility (75ALS172 series)
• RoHS3 compliance maintenance
• Active product status for long-term availability

The substitute part SN75ALS172ADWR shares the same base product number (75ALS172) and manufacturer, ensuring functional equivalence within the Interface category. The substitute maintains ROHS3 compliance and transitions from Obsolete to Active product status, providing improved procurement sustainability.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production: The SN75ALS172ADWR is the appropriate selection for new applications. This substitute part maintains identical base product number designation (75ALS172) and manufacturer source (Texas Instruments), ensuring functional compatibility. The Active product status of SN75ALS172ADWR provides superior long-term availability and supply chain reliability compared to the Obsolete SN75ALS172N.

Compliance Considerations: Both parts maintain ROHS3 compliance. The SN75ALS172ADWR additionally carries REACH Unaffected status and defined Moisture Sensitivity Level (MSL) classification (Level 1), providing enhanced environmental and handling documentation for manufacturing processes.

Inventory and Procurement: Current inventory levels support both parts. The SN75ALS172ADWR inventory (3920 Pcs) exceeds the SN75ALS172N inventory (2064 Pcs), supporting sustained procurement for production requirements.

Frequently Asked Questions (FAQ)

Q: Can SN75ALS172ADWR directly replace SN75ALS172N in existing applications?

A: Yes. Both parts share the identical base product number (75ALS172) and are manufactured by Texas Instruments within the Interface category. The substitute maintains all specified compliance requirements (ROHS3).

Q: What is the primary reason for substitution?

A: The SN75ALS172N carries Obsolete product status, which restricts future availability. The SN75ALS172ADWR maintains Active status, ensuring continued supply and manufacturing support.

Q: Are there packaging differences between these parts?

A: The SN75ALS172ADWR is specified as 20-SOIC (0.295", 7.50mm Width) Surface Mount package. Packaging information for the SN75ALS172N is not provided in the available parameters.

Q: What is the significance of the MSL rating difference?

A: The SN75ALS172N lists MSL as Not Applicable, while SN75ALS172ADWR specifies MSL Level 1 (Unlimited). MSL Level 1 indicates the component has unlimited shelf life under standard storage conditions, simplifying inventory management and reducing moisture-related handling requirements.

Q: Are both parts ROHS3 compliant?

A: Yes. Both SN75ALS172N and SN75ALS172ADWR maintain ROHS3 compliance status.
