MP-1-R 7.372800

Overview

The MtronPTI MP-1-R 7.372800 is a crystal resonator housed in an HC-49/U package. It operates at a nominal frequency of 7.3728 MHz with a frequency stability of ±30 ppm. The component features an equivalent series resistance (ESR) of 50 Ohms and supports a load capacitance of 18 pF. This device is designed for precise timing applications requiring stable oscillation within standard industrial temperature ranges.

Feature Summary

• HC-49/U through-hole package design
• ±30 ppm frequency stability
• 50 Ohm equivalent series resistance
• 18 pF load capacitance support

Applications

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

Procurement Notes

Verify the specific frequency tolerance variant, as documentation references both ±30 ppm and ±50 ppm specifications for this part number. Confirm the load capacitance requirement matches the target circuit design. Ensure the HC-49/U package dimensions align with the PCB footprint constraints. Cross-reference the manufacturer's latest datasheet to confirm RoHS compliance status and operating temperature range before finalizing procurement.

Selection Notes

Select this component when a standard HC-49/U form factor is required for through-hole mounting. The 7.3728 MHz frequency is suitable for baud rate generation in serial communications. Consider the 50 Ohm ESR value for oscillator circuit compatibility. Verify that the ±30 ppm stability meets the system's timing accuracy requirements compared to lower-cost alternatives.

Part Context

This part belongs to the MtronPTI MP-1 series of fundamental mode AT-cut crystals. The series offers various frequency options within the HC-49/U package. The MP-1-R suffix typically indicates a specific reel or tape configuration, though the base electrical characteristics remain consistent with the standard MP-1 family specifications provided by the manufacturer.

Replacement Considerations

Direct substitutes include other manufacturers' HC-49/U crystals with identical 7.3728 MHz frequency, ±30 ppm stability, 50 Ohm ESR, and 18 pF load capacitance. Ensure mechanical lead spacing matches the original component. Verify that the replacement part meets the same environmental and reliability standards.
