Crystals Procurement Notes

Verify the current manufacturing status before procurement as this part may be obsolete. Confirm that the 4-SOJ package dimensions and pin spacing match the target PCB footprint. Ensure the circuit design accommodates the specified 18 pF load capacitance and 150 Ohm ESR limits. Validate compliance with RoHS standards if required by the final product specifications.

Crystals Selection Notes

Select this component when a low-profile SMD crystal is required for 4 MHz applications. Consider the ±30 ppm tolerance and ±50 ppm stability against system requirements. Verify that the operating temperature range of -20°C to +70°C meets environmental conditions. Check compatibility with the intended driving level of 100 µW to prevent overdriving the crystal.

Crystals Part Context

This component belongs to the ABSM2 series of molded plastic SMD crystals from Abracon LLC. The series is characterized by its suitability for RoHS-compliant reflow processes and availability in various frequencies. The ABSM2 series provides a compact alternative to through-hole crystals, facilitating automated assembly in modern electronics manufacturing.

Crystals Replacement Considerations

Direct substitutes include the ECS-320-18-7SX-TR from ECS Inc., which offers similar electrical characteristics. Other potential replacements should match the 4 MHz frequency, 18 pF load capacitance, and 4-SOJ package form factor.
