7B-32.000MEEQ-T

Crystals Overview

The 7B-32.000MEEQ-T is a quartz crystal resonator manufactured by TXC Corporation, designed for surface-mount applications. It operates at a fundamental frequency of 32 MHz with a frequency tolerance and stability of ±10 ppm. The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 40 Ohms. It is housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a maximum height of 1.05 mm. The device supports a commercial operating temperature range from -20°C to +70°C.

Crystals Feature Summary

• High frequency stability of ±10 ppm ensures precise timing performance.
• Compact 5.00 mm x 3.20 mm SMD footprint facilitates automated assembly.
• Low equivalent series resistance of 40 Ohms for efficient oscillation.

Crystals Applications

• General-purpose clock signal generation in consumer electronics
• Timing references for microcontroller-based systems
• Communication interface synchronization circuits

Crystals Procurement Notes

This component is officially obsolete and no longer manufactured by TXC Corporation. Procurement should focus on verified substitute part numbers rather than original stock. Buyers must confirm availability through authorized distributors or secondary market suppliers, as direct factory orders are unavailable. Verify that replacement components meet the same electrical specifications and mechanical dimensions to ensure circuit compatibility.

Crystals Selection Notes

Engineers replacing this obsolete part should prioritize components with identical frequency, load capacitance, and ESR values. The physical package dimensions (5.00mm x 3.20mm) and pin configuration must match the existing PCB layout. Temperature stability requirements within the -20°C to +70°C range should be validated against alternative options to maintain system reliability under standard commercial conditions.

Crystals Part Context

The 7B series represents a line of general-purpose quartz crystals from TXC Corporation, characterized by their robust construction and suitability for mass-produced electronic devices. This specific model utilizes a standard AT-cut quartz element optimized for 32 MHz operation. The 'EQ-T' suffix typically denotes specific packaging and termination characteristics common to TXC's surface-mount product lines, though the series itself has been superseded by newer generations like the 7M series.

Crystals Replacement Considerations

The 7M-32.000MEEQ-T is documented as a similar substitute part number for the 7B-32.000MEEQ-T. Both share the same 32 MHz frequency, ±10 ppm tolerance, 10 pF load capacitance, and 4-SMD package form factor. Verification of ESR and temperature range compatibility is recommended before finalizing the substitution.
