Frequently Asked Questions (FAQ)

Q: Can the SXO75C3A171-10.000M be used as a direct replacement for the 7W-10.000MBB-T without PCB modifications?

A: Yes. The SXO75C3A171-10.000M is physically and electrically compatible with the 7W-10.000MBB-T. Both components share identical package dimensions (7.00mm x 5.00mm), 4-SMD No Lead configuration, and surface mount footprint. No PCB layout changes are required.

Q: What is the difference in maximum supply current between these two parts?

A: The 7W-10.000MBB-T specifies 20mA maximum supply current, while the SXO75C3A171-10.000M specifies 16mA maximum supply current. The substitute part draws less current, which is compatible with designs rated for the original specification.

Q: Are there any height differences that could affect PCB assembly?

A: The seated height differs slightly: 7W-10.000MBB-T is 1.42mm maximum, while SXO75C3A171-10.000M is 1.60mm maximum. This 0.18mm variance is within typical PCB assembly tolerances and does not affect component placement or clearance in standard applications.

Q: Does the substitute part meet current regulatory standards?

A: Yes. The SXO75C3A171-10.000M holds ROHS3 Compliant status, which represents enhanced compliance over the original part's RoHS Compliant designation. Both parts maintain REACH Unaffected status.

Q: Why is the original part classified as Obsolete?

A: The 7W-10.000MBB-T is classified as Obsolete by TXC CORPORATION. The SXO75C3A171-10.000M from Suntsu Electronics, Inc. is classified as Active, providing a viable path for continued production support and supply chain reliability.

Q: Are the frequency stability specifications identical?

A: Yes. Both the 7W-10.000MBB-T and SXO75C3A171-10.000M specify ±50ppm frequency stability, ensuring equivalent timing accuracy for applications requiring this oscillator.

Q: Can this substitute be used in new designs?

A: Yes. The SXO75C3A171-10.000M is an Active product with full availability. It is suitable for both replacement applications and new design implementations requiring a 10 MHz CMOS oscillator with enable/disable functionality at 3.3V supply voltage.
