Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMP6131DYAT is determined by strict equivalence across the following parameters:

• Resistance value: 10 kOhms at 25°C
• Resistance tolerance: ±1%
• Operating temperature range: -40°C ~ 125°C
• Package type: SC-79, SOD-523 (SOT-5X3)
• Surface mount configuration
• RoHS3 compliance
• Moisture sensitivity level: 3 (168 Hours)

The TMP6131DYAR qualifies as a direct substitute based on identical electrical specifications and package requirements. The primary distinction is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is available in Cut Tape (CT) & Digi-Reel® format.

Parameter Comparison

Engineering Selection Recommendations

The TMP6131DYAR is the manufacturer-recommended substitute for the TMP6131DYAT. Both parts maintain identical electrical and thermal specifications, ensuring functional equivalence in circuit applications. The TMP6131DYAR carries Active product status, providing ongoing availability and supply chain stability compared to the Last Time Buy status of the main part. Both components meet ROHS3 compliance and REACH unaffected requirements, supporting regulatory requirements for industrial and commercial applications.

Selection between these parts should be based on packaging requirements: Tape & Reel format for automated assembly processes, or Cut Tape & Digi-Reel® format for lower-volume or mixed-component procurement scenarios.

Frequently Asked Questions (FAQ)

Q: Can TMP6131DYAR be used as a direct replacement for TMP6131DYAT?

A: Yes. Both parts are electrically and mechanically identical, with 10 kOhms resistance at ±1% tolerance, -40°C to 125°C operating range, and SC-79/SOD-523 surface mount package. The difference is packaging format only.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) is continuous reel format optimized for high-volume automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® provides flexibility for lower quantities and mixed-component orders, with components supplied in tape segments or alternative reel formats.

Q: Why is TMP6131DYAT marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued this specific packaging configuration. Existing inventory is available for final orders, but long-term supply cannot be guaranteed. The TMP6131DYAR in Active status is the recommended path for ongoing production requirements.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts operate identically across all specified parameters: resistance value, tolerance, temperature range, and compliance certifications.

Q: What are the moisture sensitivity implications for PCB assembly?

A: Both parts carry MSL 3 (168 Hours) rating, requiring standard moisture control procedures during storage and assembly. Components must be stored in dry conditions and baked according to IPC standards if moisture absorption limits are approached.
