Crystals Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when ordering from distributors. Confirm that the operating temperature range of -10°C to +70°C meets your application requirements, as some variants may offer wider ranges. Ensure the 18 pF load capacitance matches your circuit design specifications before procurement.

Crystals Selection Notes

Select this component when a 27 MHz fundamental mode crystal is required for SMD assembly. Consider the ±30 ppm stability limit for timing accuracy needs. Compare ESR values against oscillator driver strength capabilities. Verify package dimensions fit within PCB layout constraints compared to alternative 3225 or similar sized crystals.

Crystals Part Context

This part belongs to the TXC 7M series of surface mount crystals. The series offers various frequencies and packages, typically utilizing fundamental mode operation. The 7M-27.000MAAJ-T specifically addresses the common 27 MHz frequency point used in legacy and modern digital interfaces.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' 27 MHz crystals in 3225 SMD packages with 18 pF load capacitance. Check compatibility regarding ESR limits and frequency stability tolerances. Ensure replacement parts support the same -10°C to +70°C operating range if environmental conditions are strict.
