9B-19.200MEEJ-B

Crystals Overview

The 9B-19.200MEEJ-B is a through-hole quartz crystal manufactured by TXC Corporation, designed for standard clock applications. It operates at a fundamental frequency of 19.2 MHz with a frequency stability and tolerance of ±10 ppm. The component utilizes an HC-49/US package and requires an external load capacitance of 18 pF. It features a low equivalent series resistance (ESR) of 30 Ohms to support efficient circuit operation. The device is rated for a temperature range of -20°C to +70°C and complies with RoHS3 specifications. This part is currently listed as obsolete in public distributor records.

Crystals Feature Summary

• Low ESR design for stable drive levels
• Standard HC-49/US through-hole packaging

Crystals Applications

• Microcontroller clock sources
• Digital logic timing circuits
• Communication interface synchronization

Crystals Procurement Notes

This component is officially classified as obsolete by the manufacturer and distributors. Sourcing new units from authorized channels is not possible. Engineers must verify end-of-life status before finalizing designs. Procurement should focus on identifying qualified replacement parts that match electrical parameters and mechanical footprint requirements to ensure long-term supply chain stability.

Crystals Selection Notes

Designers requiring this specific frequency should evaluate alternative surface-mount or through-hole crystals from the same manufacturer. Key selection criteria include matching the 19.2 MHz frequency, 18 pF load capacitance, and ±10 ppm stability. Package compatibility is critical when transitioning from the HC-49/US form factor to modern PCB layouts. Verify thermal performance within the specified operating range during substitution.

Crystals Part Context

The 9B series represents TXC Corporation's line of general-purpose quartz crystals. These components are widely used in consumer electronics and industrial equipment where cost-effective, reliable timing solutions are required. The HC-49/US package has been a standard industry format for decades, facilitating easy integration into legacy and mixed-technology boards.

Crystals Replacement Considerations

Public records indicate no direct substitute part numbers provided by TXC Corporation for this obsolete item. Designers should consult distributor cross-reference tools for functionally equivalent crystals with compatible pinouts and electrical characteristics.
