Frequently Asked Questions (FAQ)

Q: Can the TFPT1206L1002DM be used as a direct replacement for TFPT1206L1002FZ?

A: Yes. Both components have identical resistance values (10 kOhms), operating temperature ranges (-55°C ~ 150°C), power ratings (125 mW), and 1206 (3216 Metric) package specifications. The substitute offers improved tolerance and compliance characteristics.

Q: What is the difference in resistance tolerance between these parts?

A: The TFPT1206L1002FZ has ±1% tolerance, while the TFPT1206L1002DM has ±0.5% tolerance. The tighter tolerance of the substitute provides greater accuracy in temperature sensing applications.

Q: Are there packaging differences between these parts?

A: The TFPT1206L1002FZ packaging is not specified in available data. The TFPT1206L1002DM is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly. Both use identical 1206 (3216 Metric) case dimensions.

Q: Does the TFPT1206L1002DM meet RoHS requirements?

A: Yes. The TFPT1206L1002DM is ROHS3 compliant, whereas the original TFPT1206L1002FZ is RoHS non-compliant. This makes the substitute suitable for applications requiring RoHS compliance.

Q: Is the TFPT1206L1002DM suitable for automotive applications?

A: Yes. The TFPT1206L1002DM carries AEC-Q200 qualification, making it suitable for automotive-grade applications. The original part does not specify automotive qualification.
