Procurement Notes

Verify that the received components match the exact part number QT161S-26.000MDDV-T from manufacturer QST. Confirm package type is 4-SMD No Lead and physical dimensions are 1.60mm x 1.20mm. Ensure documentation specifies 26 MHz frequency and ±20 ppm stability. Check for RoHS compliance status if required by project specifications. Validate supplier authenticity through official channels.

Selection Notes

Select this component when a 26 MHz timing source is required in minimal footprint designs. The 4-SMD no-lead package supports automated surface-mount assembly processes. Consider the ±20 ppm stability requirement against system clock accuracy needs. Verify compatibility with 8 pF load capacitance requirements of the target circuit. Evaluate thermal performance within the -20°C to 70°C operating range for environmental suitability.

Part Context

This crystal belongs to the QT161S series manufactured by QST, designed for surface-mount applications. The series offers various frequency options within a standardized small outline package format. These components serve as fundamental timing elements in digital electronics requiring precise frequency references without active oscillation capabilities.

Replacement Considerations

Direct substitutes must maintain identical 26 MHz frequency, 4-SMD no-lead package, and 1.60x1.20mm dimensions. Verify equivalent electrical parameters including 8 pF load capacitance and ±20 ppm stability. Cross-reference with other manufacturers offering similar SMD crystals only if pinout and mechanical constraints align perfectly.
