TMP6331QDECTQ1 Equivalent & Substitute Parts

Part Overview

The TMP6331QDECTQ1 is a PTC thermistor rated at 100 kOhms with ±1% resistance tolerance, designed for automotive-grade applications. This surface-mount component operates across the temperature range of -40°C to 125°C and is housed in a 0402 (1006 Metric) package. The part carries AEC-Q100 automotive qualification and ROHS3 compliance.

The TMP6331QDECTQ1 is designated as Last Time Buy, indicating that Texas Instruments has discontinued or will discontinue production. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for ongoing production requirements.

Substitute Part Grouping Explanation

Substitution of the TMP6331QDECTQ1 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 100 kOhms at 25°C
• Resistance Tolerance: ±1%
• Operating Temperature Range: -40°C to 125°C
• Package Configuration: 0402 (1006 Metric), 2-X1SON (1x0.6)
• Mounting Technology: Surface Mount
• Automotive Grade: AEC-Q100 qualified
• Regulatory Compliance: ROHS3 compliant

Substitute parts must match all parameters listed above to ensure functional and mechanical compatibility within the original design. The TMP6331QDECRQ1 meets all substitution criteria and is classified as an equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The TMP6331QDECRQ1 is the direct equivalent substitute for the TMP6331QDECTQ1. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications. The primary distinction is product status: the original part is designated Last Time Buy, while the substitute part maintains Active status.

The TMP6331QDECRQ1 is suitable for direct replacement in all applications where the TMP6331QDECTQ1 was originally specified. Both parts carry AEC-Q100 automotive qualification and ROHS3 compliance, ensuring regulatory and quality standards are maintained. The substitute part is currently in active production with higher inventory availability (10,200 pieces versus 4,834 pieces for the original part).

No design modifications, circuit alterations, or additional validation are required when transitioning from the TMP6331QDECTQ1 to the TMP6331QDECRQ1, as all functional and mechanical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the TMP6331QDECRQ1 be used as a direct replacement for the TMP6331QDECTQ1?

A: Yes. The TMP6331QDECRQ1 is a direct equivalent substitute. All electrical parameters (resistance value, tolerance, operating temperature range) and mechanical specifications (package, mounting type) are identical. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The TMP6331QDECTQ1 is Last Time Buy, indicating discontinued or discontinuing production. The TMP6331QDECRQ1 is Active and currently in production. Both parts are functionally and mechanically identical.

Q: Are both parts automotive-qualified?

A: Yes. Both the TMP6331QDECTQ1 and TMP6331QDECRQ1 carry AEC-Q100 automotive qualification and are suitable for automotive-grade applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory and environmental compliance is equivalent.

Q: Is the package configuration identical?

A: Yes. Both parts use the 0402 (1006 Metric) package with 2-X1SON (1x0.6) supplier device package configuration. PCB footprints and assembly processes are identical.

Q: Why should I transition to the TMP6331QDECRQ1?

A: The TMP6331QDECRQ1 is the recommended substitute because it maintains Active production status, ensuring long-term supply chain availability. The original part's Last Time Buy status indicates limited future availability.
