7S-19.200MAHE-T

Crystals Overview

The 7S-19.200MAHE-T is a surface-mount quartz crystal resonator manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 19.2 MHz with a frequency tolerance and stability of ±30 ppm. The component features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 100 Ohms. Housed in a compact 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a maximum seated height of 0.85 mm, it supports operation within an extended temperature range of -40°C to +85°C.

• Embedded microcontroller timing circuits

Crystals Procurement Notes

This component is officially obsolete and no longer manufactured by TXC Corporation. Procurement should focus on verified parameter-equivalent substitutes or similar alternatives from the manufacturer's current portfolio. Verify that replacement parts match the original electrical specifications, including frequency, load capacitance, and ESR, to ensure circuit compatibility. Confirm package dimensions and pin configuration before integration.

Crystals Selection Notes

Designers must account for the discontinued status when selecting this part. Evaluate available substitutes based on strict adherence to the 19.2 MHz frequency, 12 pF load capacitance, and ±30 ppm stability requirements. Ensure the replacement component supports the required -40°C to +85°C operating range. Cross-reference datasheets to confirm mechanical fit and soldering profile compatibility for surface-mount processes.

Crystals Part Context

The 7S series represents a line of miniature quartz crystals optimized for space-constrained electronic designs. This specific model utilizes a 4-SMD no-lead package, offering reliability in high-volume manufacturing environments.
