QT532G-19.200MAAE-T

Overview

QT532G-19.200MAAE-T is a surface-mount quartz crystal oscillator manufactured by QST. It operates at a nominal frequency of 19.2 MHz with a fundamental working mode. The component features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 50 Ohms. Frequency stability and tolerance are specified at ±30 ppm. It utilizes a 2-SMD, no-lead package with dimensions of 5.00 mm x 3.20 mm and a maximum height of 1.35 mm. The device supports a commercial operating temperature range of -20°C to +70°C and complies with RoHS3 standards.

Feature Summary

• Fundamental mode quartz crystal operation for precise frequency generation
• Surface-mount design in a compact 2-SMD no-lead package
• Commercial grade temperature stability within specified limits

Applications

• General purpose clock signal generation in electronic circuits
• Timing reference for microcontrollers and digital logic systems
• Frequency control in communication modules requiring 19.2 MHz stability

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure exact electrical parameters match system requirements. Confirm that the 2-SMD no-lead package dimensions align with PCB footprint constraints. Check current product status as availability may vary between active and obsolete classifications depending on the supply chain source.

Selection Notes

Select this component when a 19.2 MHz fundamental frequency is required with ±30 ppm stability. Ensure the circuit design accommodates a 12 pF load capacitance and 50 Ohm ESR. Verify that the -20°C to +70°C operating range meets the environmental conditions of the target application. Compare physical dimensions against available board space for the 5.00mm x 3.20mm package.

Part Context

The QT532G series represents a line of surface-mount quartz crystals from QST. This specific model provides a standard frequency option within the series. It shares common packaging and mounting characteristics with other variants in the family, differing primarily in frequency and specific tolerance grades. The series is designed for integration into modern electronics manufacturing processes.

Replacement Considerations

The TXC CORPORATION part number 7A-19.200MAAE-T is documented as a parameter-equivalent substitute. Both components share identical electrical specifications including 19.2 MHz frequency, 12 pF load capacitance, and ±30 ppm stability. Verify pin compatibility and mechanical fit before substitution.
