LFXTAL003151

Overview

The LFXTAL003151 is a parallel fundamental quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 8 MHz with a frequency tolerance of ±30 ppm and stability of ±50 ppm. The component utilizes a 16 pF load capacitance and features a series resistance of 40 Ω. Designed for surface mount applications, it is housed in an HC-49/US package. The device supports through-hole mounting configurations and is compliant with RoHS standards.

Feature Summary

• Hermetically sealed construction using resistance welding within an inert atmosphere to ensure long-term reliability.
• Glass-to-metal seals on leads provide robust environmental protection against moisture and contaminants.
• Parallel fundamental resonance mode ensures stable oscillation characteristics for precise timing control.

Applications

• Precision timing circuits requiring stable 8 MHz reference frequencies
• Microcontroller clock generation systems
• Industrial communication interface synchronization

Procurement Notes

Verify the specific packaging variant (Bulk or Reel) required for your assembly process, as availability may vary between tape-and-reel and bulk formats. Confirm that the HC-49/US footprint matches your PCB design constraints. Ensure the supplier provides traceability documentation for RoHS compliance and material declarations to meet regulatory requirements for electronic assemblies.

Selection Notes

Select this component when a standard 8 MHz frequency is required with moderate stability specifications. The HC-49/US package offers a balance between size and mechanical robustness suitable for general-purpose electronics. Consider the 40 Ω series resistance for oscillator circuit loading calculations. This part is appropriate for applications where cost-effectiveness and proven reliability are prioritized over ultra-low phase noise performance.

Part Context

This quartz crystal belongs to IQD Frequency Products' extensive portfolio of frequency control solutions. IQD is a recognized leader in the frequency market, offering a wide range of crystals and oscillators for diverse industries including automotive, industrial, and consumer electronics. The LFXTAL series represents standard leaded and surface-mount crystals designed for general-purpose timing applications.

Replacement Considerations

Direct substitutes must match the 8 MHz frequency, 16 pF load capacitance, and HC-49/US package dimensions. Verify equivalent electrical parameters such as series resistance and frequency tolerance. Cross-reference with other manufacturers' HC-49/US 8 MHz crystals ensuring identical pinout and sealing technology for mechanical interchangeability.
