Frequently Asked Questions (FAQ)

Q: Can TMC05075R00FE02 be used as a direct replacement for THS5075RJ?

A: Yes. Both parts share identical resistance (75 Ohms), power rating (50W), composition (wirewound), mounting features (flanges), lead style (solder lugs), and housing type (aluminum). The substitute part meets or exceeds all critical electrical and mechanical specifications.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Tolerance: TMC05075R00FE02 offers ±1% versus THS5075RJ's ±5%; (2) Temperature Coefficient: TMC05075R00FE02 has ±20ppm/°C versus THS5075RJ's ±50ppm/°C; (3) Operating Temperature Range: TMC05075R00FE02 extends to 250°C versus THS5075RJ's 200°C; (4) Physical dimensions are slightly different but both use identical mounting and lead styles.

Q: Are there any dimensional compatibility concerns?

A: Minor dimensional differences exist. TMC05075R00FE02 is slightly smaller (1.968" L x 1.140" W versus 2.008" L x 1.181" W) and has a lower seated height (0.625" versus 0.669"). These differences are within typical PCB layout tolerances for flanged chassis mount resistors. Verify mounting hole spacing and clearance in your specific application.

Q: Do both parts meet the same compliance standards?

A: Yes. Both THS5075RJ and TMC05075R00FE02 are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8533.29.0000) classifications.

Q: Which part should be selected for high-temperature applications?

A: TMC05075R00FE02 is suitable for applications requiring operation up to 250°C, while THS5075RJ is rated to 200°C. For applications approaching or exceeding 200°C, TMC05075R00FE02 is the appropriate selection.

Q: What is the significance of the tolerance difference?

A: THS5075RJ has ±5% tolerance while TMC05075R00FE02 has ±1% tolerance. The tighter tolerance of the substitute part results in more precise resistance values, which is beneficial for applications requiring accurate impedance matching or precision signal conditioning circuits.
