9B04000166

Crystals Overview

The 9B04000166 is a fundamental mode quartz crystal resonator manufactured by TXC Corporation. It operates at a nominal frequency of 4 MHz with a load capacitance of 30 pF and a frequency tolerance of ±30 ppm. The component features an equivalent series resistance (ESR) of 150 Ohms and utilizes the HC-49/US through-hole package, measuring 11.50 mm in length and 5.00 mm in width. It supports a standard operating temperature range from -20°C to +70°C.

Crystals Feature Summary

• Fundamental resonance mode operation for stable timing signals
• Through-hole mounting configuration compatible with standard PCB layouts
• Compliance with RoHS3 environmental standards

Crystals Applications

• General-purpose clock generation circuits
• Microcontroller system oscillators
• Industrial control equipment timing references

Crystals Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer, with discontinuance notifications issued in March 2021. Procurement is restricted to remaining surplus stock or secondary market channels. Verify part authenticity and physical condition carefully, as original factory packaging may be compromised during extended storage periods.

Crystals Selection Notes

Engineers should prioritize alternative components due to the confirmed production termination status. When evaluating replacements, ensure the new candidate matches the required 4 MHz frequency, 30 pF load capacitance, and HC-49/US form factor to maintain mechanical and electrical compatibility within existing designs.

Crystals Part Context

The 9B04000166 belongs to the 9B series of discrete crystals from TXC Corporation. This series typically provides cost-effective timing solutions for consumer and industrial electronics. As a discontinued item, it represents legacy hardware that requires careful lifecycle management during product maintenance or redesign phases.

Crystals Replacement Considerations

Direct substitute part numbers are not explicitly documented in available public records. Designers must perform manual cross-referencing to identify functionally equivalent crystals from other manufacturers that meet the specific electrical and dimensional requirements.
