Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMP6331DYAT is determined by electrical and mechanical parameter equivalence. The primary substitution criteria are:

Electrical Parameters:

• Resistance value at 25°C: 100 kOhms
• Resistance tolerance: ±1%
• Operating temperature range: -40°C ~ 150°C

Mechanical Parameters:

• Package type: SC-79, SOD-523
• Mounting configuration: Surface Mount
• Supplier device package: SOT-5X3
• Moisture sensitivity level: 3 (168 Hours)

Parts meeting all these criteria are classified as direct substitutes. The TMP6331DYAR satisfies all specified parameters and is therefore a valid equivalent for the TMP6331DYAT.

Parameter Comparison

Engineering Selection Recommendations

The TMP6331DYAR is the direct substitute for the TMP6331DYAT. Both components are manufactured by Texas Instruments and share identical electrical specifications and mechanical packaging. The primary distinction is product status: the TMP6331DYAT is designated Last Time Buy, while the TMP6331DYAR maintains Active status with significantly higher inventory availability (6210 pieces versus 1887 pieces).

For new designs or ongoing production requiring this thermistor specification, the TMP6331DYAR is the appropriate selection. The Active product status ensures continued manufacturing support and supply chain stability. Both parts comply with identical RoHS and MSL classifications, ensuring equivalent reliability and handling requirements in manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can the TMP6331DYAR be used as a direct replacement for the TMP6331DYAT in existing designs?

A: Yes. The TMP6331DYAR is a direct substitute. Both components have identical resistance values (100 kOhms ±1%), operating temperature ranges (-40°C ~ 150°C), and package configurations (SC-79, SOD-523). No circuit modifications are required.

Q: What is the difference between the TMP6331DYAT and TMP6331DYAR?

A: The components are electrically and mechanically identical. The primary difference is product lifecycle status: TMP6331DYAT is Last Time Buy (discontinued), while TMP6331DYAR is Active (current production). The TMP6331DYAR also has higher inventory availability.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the SC-79/SOD-523 package with SOT-5X3 supplier device package designation. PCB footprints and assembly processes are identical.

Q: What is the MSL rating, and does it differ between these parts?

A: Both parts have MSL rating 3 (168 Hours). This indicates identical moisture sensitivity and handling requirements during manufacturing and storage.

Q: Should I transition to the TMP6331DYAR for new production?

A: Yes. The TMP6331DYAR is the recommended part for new designs and ongoing production due to its Active product status and superior supply availability.
