7B-16.000MAAE-T

Crystals Overview

The 7B-16.000MAAE-T is a discontinued quartz crystal resonator manufactured by TXC Corporation, designed for surface-mount applications. It operates at a fundamental frequency of 16 MHz with a load capacitance of 12 pF and a frequency tolerance of ±30 ppm. The component features an equivalent series resistance (ESR) of 40 Ohms and utilizes a 4-SMD, no-lead package measuring 5.00 mm in length, 3.20 mm in width, and 1.05 mm in maximum height. It supports a base harmonic operating mode within a temperature range of -20°C to +70°C.

Crystals Feature Summary

Crystals Procurement Notes

This specific part number is officially marked as obsolete and no longer in production by the manufacturer. Procurement must focus on identifying verified replacement components or alternative series from the same supplier that match the required electrical parameters and physical dimensions. Direct sourcing of new units is not possible through standard manufacturing channels.

Crystals Selection Notes

Engineers should prioritize components with identical 16 MHz frequency, 12 pF load capacitance, and ±30 ppm tolerance. Verify that the substitute supports SMD mounting in a similar form factor to ensure mechanical compatibility. Confirm that the replacement meets the necessary operating temperature range and ESR specifications for the target circuit design.

Crystals Part Context

The 7B series represents a line of small-volume SMD crystals optimized for wireless and consumer electronics. This model specifically targets applications requiring reduced PCB area compared to traditional packages like HC-49S. It is part of TXC's portfolio aimed at improving EMI performance and reliability in compact digital devices.

Crystals Replacement Considerations

Potential substitutes include the 7M-20.000MAAE-T, 7V-20.000MAAE-T, 7V-20.000MAAQ-T, AB-20.000MAGE-T, and ABM8G-20.000MHZ-B4Y-T. Note that these listed alternatives are specified for 20 MHz; verify if other 16 MHz variants exist within these series.
