Engineering Selection Recommendations

Both the 7C-16.000MBA-T and SXO53C3C171-16.000M are Active products with current manufacturing support. Selection between these parts is based on the following engineering considerations:

TXC 7C-16.000MBA-T: Specified maximum supply current of 30mA. Packaged in Tape & Reel format. RoHS Compliant certification. Suitable for applications where TXC supply chain continuity is prioritized.

Suntsu SXO53C3C171-16.000M: Specified maximum supply current of 16mA, representing lower power consumption during operation. Packaged in Bulk format. ROHS3 Compliant certification. Suitable for applications where power efficiency and extended compliance standards are required.

Both parts maintain identical electrical performance, frequency stability, and physical compatibility. The choice between manufacturers depends on supply availability, packaging requirements, and power budget constraints specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the SXO53C3C171-16.000M replace the 7C-16.000MBA-T without circuit modification?

A: Yes. Both parts share identical electrical specifications, frequency output, supply voltage, and 4-SMD No Lead package dimensions. Pin-for-pin replacement is supported without circuit redesign.

Q: What is the significance of the different maximum supply currents (30mA vs. 16mA)?

A: The maximum supply current specification indicates the upper limit of current draw under specified operating conditions. The Suntsu part operates at a lower maximum current, which may provide power efficiency benefits in battery-powered or power-constrained applications. Both values are within typical operating ranges for 16 MHz CMOS oscillators.

Q: Are there compliance differences between RoHS and ROHS3?

A: Both certifications indicate compliance with Restriction of Hazardous Substances directives. ROHS3 represents the current version of the standard. Both parts meet hazardous substance restrictions and are suitable for modern electronic applications.

Q: Does packaging format (Tape & Reel vs. Bulk) affect electrical performance?

A: No. Packaging format affects logistics, handling, and automated assembly processes but does not alter electrical characteristics or functional performance. Selection depends on manufacturing process requirements and inventory management practices.

Q: Are both parts suitable for the full -10°C to 70°C operating temperature range?

A: Yes. Both the 7C-16.000MBA-T and SXO53C3C171-16.000M are specified for identical operating temperature ranges of -10°C to 70°C, ensuring consistent frequency stability across this temperature band.
