Crystals Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging if required by assembly equipment. Confirm the 4-SOJ footprint dimensions match the PCB layout, specifically the 9.40mm pitch. Ensure the operating temperature range of -10°C to +70°C meets the environmental requirements of the final application. Cross-reference the manufacturer datasheet for soldering profile recommendations.

Crystals Selection Notes

Select this component when a 15 MHz surface-mount crystal is required with standard commercial temperature ratings. The 18pF load capacitance must align with the oscillator circuit design. Consider the ±30ppm tolerance for applications requiring moderate frequency accuracy. The 4-SOJ package offers a compact solution compared to through-hole alternatives while maintaining mechanical stability.

Crystals Part Context

This part belongs to the ECS Inc. family of surface-mount crystals. It serves as a frequency reference component for electronic systems requiring stable oscillation. The 4-SOJ package distinguishes it from other SMD formats like HC-49 or smaller chip packages. It is engineered for general-purpose timing applications in consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes must match the 15 MHz frequency, 18pF load capacitance, and 4-SOJ package dimensions. Verify that alternative components meet the same ±30ppm tolerance and -10°C to +70°C operating range. Check ESR compatibility to ensure oscillator startup reliability. Consult manufacturer cross-reference lists for verified equivalents.
