Crystals Procurement Notes

Verify the specific suffix '5PX' against the official ECS datasheet to confirm the exact case size and terminal configuration. Ensure the required load capacitance matches the circuit design specifications. Confirm that the operating temperature range of -10°C to +70°C meets the environmental requirements of the target application before procurement.

Crystals Selection Notes

Select this component when a surface-mount solution is required for 12 MHz timing applications. The 18 pF load capacitance must align with the host circuit's capacitive loading requirements. Consider the 50 ohm ESR and 50 µW drive level limits to ensure proper oscillator circuit stability and longevity under the specified thermal conditions.

Crystals Part Context

This part belongs to the CSM-7X series of surface-mount crystals from ECS Inc. The series offers various frequency and package options designed for cost-effective mass production. The 5PX suffix denotes a specific physical dimension and lead arrangement within this product line, distinguishing it from other variants like the JEM or standard bulk packages.

Crystals Replacement Considerations

Cross-reference compatible parts such as ECS-120-20-5PX-TR if a different load capacitance is acceptable. Verify that substitute components maintain the same 12 MHz frequency, 18 pF load capacitance, and 4-SMD footprint to ensure mechanical and electrical compatibility without redesigning the PCB layout.
