LFXTAL033575

Overview

The LFXTAL033575 is a parallel fundamental quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 7.3728 MHz with a frequency tolerance of ±30 ppm and stability of ±50 ppm. The component features an 18 pF load capacitance and a maximum equivalent series resistance (ESR) of 60 Ohms. Designed for surface mount applications, it utilizes the HC49/4HSMX package with dimensions of 13.40 mm length, 4.90 mm width, and 4.30 mm maximum height. The device supports a commercial operating temperature range from -20°C to +70°C.

Feature Summary

• Surface mount construction in the HC49/4HSMX package
• Parallel fundamental resonance mode operation
• Compliance with RoHS3 and REACH regulations

Applications

• General purpose clock signal generation
• Microcontroller oscillator circuits
• Communication interface timing

Procurement Notes

Verify the specific ordering suffix required for the desired packaging format, such as tape and reel or cut tape, as availability may vary by region. Confirm that the HC49/4HSMX footprint matches the target PCB design. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number with authorized distributors to confirm current production status and compliance documentation.

Selection Notes

Select this component when a standard 7.3728 MHz reference is needed for digital logic interfacing. The HC49/4HSMX form factor allows for automated surface mount placement while maintaining compatibility with traditional through-hole layouts. Consider the 60 Ohm ESR limit to ensure proper oscillation startup within the host circuit design constraints.

Part Context

This part belongs to the IQD LFXTAL series of quartz crystals. The manufacturer provides a comprehensive portfolio of frequency control products ranging from miniature SMD packages to larger through-hole units. This specific model represents a standard commercial-grade solution suitable for mass-produced electronic equipment requiring reliable timekeeping references.

Replacement Considerations

Direct substitutes must match the 7.3728 MHz frequency, 18 pF load capacitance, and HC49/4HSMX package dimensions. Verify that alternative sources offer comparable ±30 ppm tolerance and similar ESR characteristics to maintain circuit performance.
