Crystals Procurement Notes

Verify the specific ordering suffix against the official manufacturer datasheet to ensure exact electrical parameters match project requirements. Confirm that the HC-49/US 2-SMD footprint aligns with the PCB layout. Request the latest production data sheet directly from Suzhou Hangjing Elec&Tech Co., Ltd. to validate current manufacturing status and material specifications before finalizing component selection.

Crystals Selection Notes

Select this component when a standard 25 MHz reference is required in a surface-mount configuration. Ensure the circuit design accommodates the specified 20 pF load capacitance and 100 Ohm ESR limits. Consider the ±20 ppm stability requirement relative to the system's timing accuracy needs. Verify that the operating temperature range meets the environmental conditions of the intended application.

Crystals Part Context

This part belongs to the HC-49/US series of quartz crystals, widely used as fundamental frequency references in electronic circuits. Suzhou Hangjing Elec&Tech Co., Ltd. produces these components for computing, communication, and industrial applications. The 049SS2 variant represents a surface-mount adaptation of the traditional through-hole HC-49/U package, facilitating modern PCB assembly processes while maintaining familiar mechanical dimensions.

Crystals Replacement Considerations

Cross-reference other manufacturers offering HC-49/US 2-SMD packages with identical 25 MHz frequency, 20 pF load capacitance, and ≤100 Ohm ESR. Verify pinout compatibility and mounting pad dimensions to ensure direct replacement without PCB redesign.
