7B-16.384MAAJ-T

Crystals Overview

The TXC Corporation 7B-16.384MAAJ-T is a quartz crystal resonator operating at a fundamental frequency of 16.384 MHz. It features a frequency stability and tolerance of ±30 ppm, with a load capacitance of 18 pF. The component utilizes a third overtone mode and has an equivalent series resistance (ESR) of 120 Ohms. It is housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm x 1.05 mm. The device supports surface mount installation and operates within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Third overtone operation for precise frequency control
• Compact 4-SMD no-lead surface mount footprint
• Standard 18 pF load capacitance compatibility

Crystals Applications

• General purpose clock signal generation
• Microcontroller oscillator circuits
• Communication module timing references

Crystals Procurement Notes

This component is officially classified as obsolete and has been discontinued by the manufacturer. Production has ceased, meaning new units are no longer manufactured. Procurement is restricted to remaining stock from authorized distributors or secondary market suppliers. Designers should verify the authenticity and storage history of available inventory carefully due to the end-of-life status.

Crystals Selection Notes

Engineers requiring this specific frequency should evaluate the successor model 7M-16.384MAAJ-T, which shares similar electrical characteristics but may have updated manufacturing processes. Alternative crystals from other manufacturers with matching 16.384 MHz frequency, 18 pF load capacitance, and compatible physical dimensions should be considered for new designs to ensure long-term supply chain stability.

Crystals Part Context

The 7B series represents a line of general-purpose quartz crystals from TXC Corporation designed for cost-effective applications. This specific part number belongs to the standard SMD crystal family, characterized by its reliability and widespread use in consumer electronics and industrial equipment where moderate frequency stability is sufficient.

Crystals Replacement Considerations

The direct successor part number is 7M-16.384MAAJ-T. Other compatible alternatives include ABM3-16.384MHZ-B4Y-T from Abracon LLC, provided pinout and electrical parameters match the design requirements.
