Parameter Comparison

Engineering Selection Recommendations

The TMP6331DECR is the designated substitute for the TMP6331DECT. Both components are manufactured by Texas Instruments and share identical electrical and mechanical specifications. The primary distinction is product status: the TMP6331DECT is in Last Time Buy phase, while the TMP6331DECR maintains Active status with higher inventory availability (5195 Pcs versus 3195 Pcs). Both components meet ROHS3 compliance and REACH requirements, ensuring regulatory alignment for current and future production. Selection of the TMP6331DECR is appropriate for new designs and ongoing production to ensure long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can the TMP6331DECR be used as a direct replacement for the TMP6331DECT?

A: Yes. Both components are electrically and mechanically identical, with matching resistance values (100 kOhms ±1%), operating temperature ranges (-40°C to 125°C), and package specifications (0402 / 1006 Metric, 2-X1SON). No circuit modifications are required.

Q: What is the difference between the TMP6331DECT and TMP6331DECR?

A: The components are functionally equivalent. The primary difference is product lifecycle status: TMP6331DECT is Last Time Buy with limited inventory, while TMP6331DECR is Active with higher stock levels.

Q: Are there any packaging or mounting differences between these parts?

A: No. Both components use identical 0402 (1006 Metric) surface mount packages with 2-X1SON (1x0.6) supplier device packaging. PCB layout and reflow profiles remain unchanged.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the TMP6331DECT and TMP6331DECR are ROHS3 Compliant and REACH Unaffected, with identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: Which part should be selected for new designs?

A: The TMP6331DECR should be selected for new designs due to its Active product status and higher inventory availability, ensuring sustained component supply throughout the product lifecycle.
