Crystals Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as the TR designation indicates tape and reel supply. Ensure compatibility with the target PCB footprint dimensions of 12.50mm x 4.60mm. Cross-reference the load capacitance requirement of 20pF against the host circuit design to maintain frequency accuracy within the specified tolerance limits.

Crystals Selection Notes

Select this component when a 10 MHz surface-mount crystal is required for space-constrained designs. The 4-SOJ form factor supports reflow soldering processes. Consider the ±30 ppm tolerance and 50 Ohm ESR specifications to ensure proper oscillator circuit startup and long-term stability requirements are met for the intended application environment.

Crystals Part Context

This part belongs to the ECS 7SX series of surface-mount crystals. The series offers various frequency options in a standardized small outline package. The 7SX designation typically refers to the specific case style and pin configuration used by ECS Inc. for their SMD crystal lineup, providing a reliable alternative to through-hole components in modern electronics manufacturing.

Crystals Replacement Considerations

Direct substitutes must match the 10 MHz frequency, 4-SOJ package, and 20pF load capacitance. Verify that any replacement component meets the same ±30 ppm tolerance and 50 Ohm ESR specifications to ensure circuit performance parity.
