TMP6131QDECRQ1 Equivalent & Substitute Parts

Part Overview

The TMP6131QDECRQ1 is a PTC thermistor temperature sensor manufactured by Texas Instruments, rated at 10 kOhms with ±1% tolerance in a 0402 (1006 Metric) surface mount package. This automotive-grade component is qualified to AEC-Q100 standards and operates across the temperature range of -40°C to 125°C. The part is currently in active production status with substantial inventory availability (10,050 pieces). Substitute parts become necessary when the active production variant is unavailable or when design requirements permit the use of equivalent specifications from the same manufacturer's product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMP6131QDECRQ1 is determined by the following critical parameters:

• Resistance value: 10 kOhms
• Resistance tolerance: ±1%
• Operating temperature range: -40°C to 125°C
• Package type: 0402 (1006 Metric)
• Supplier device package: 2-X1SON (1x0.6)
• Surface mount mounting type
• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

The TMP6131DECT meets all these electrical and mechanical specifications, making it a valid substitute despite its obsolete product status.

Parameter Comparison

Engineering Selection Recommendations

The TMP6131QDECRQ1 is the preferred selection for new designs due to its active production status and automotive-grade qualification (AEC-Q100). The TMP6131DECT is electrically and mechanically equivalent but carries an obsolete product status, indicating discontinued manufacturing. Selection of the substitute should be limited to applications where the main part is unavailable and inventory constraints require alternative sourcing. Both parts maintain identical electrical specifications, package geometry, and compliance certifications (ROHS3, REACH Unaffected).

Frequently Asked Questions (FAQ)

Q: Can TMP6131DECT be used as a direct replacement for TMP6131QDECRQ1?

A: Yes. Both parts share identical resistance values (10 kOhms ±1%), operating temperature ranges (-40°C to 125°C), package types (0402/1006 Metric), and device packages (2-X1SON 1x0.6). Electrical and mechanical compatibility is complete.

Q: What is the difference between the main part and the substitute?

A: The primary difference is product status. TMP6131QDECRQ1 is in active production, while TMP6131DECT is obsolete. Both maintain identical electrical specifications and compliance certifications.

Q: Are there any packaging differences between these parts?

A: No. Both parts use identical packaging: 0402 (1006 Metric) surface mount with 2-X1SON (1x0.6) supplier device package configuration.

Q: Does the substitute meet automotive qualification requirements?

A: TMP6131QDECRQ1 carries AEC-Q100 automotive qualification. TMP6131DECT does not list automotive qualification in the provided specifications, though it maintains identical electrical and mechanical parameters.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints for storage or handling.
