Crystals Procurement Notes

Verify the specific suffix configuration against the official Abracon datasheet to ensure compatibility with target circuit parameters. Confirm RoHS compliance status and manufacturing origin prior to procurement. Cross-reference the part number with authorized distributors to validate authenticity and traceability. Ensure storage conditions meet moisture sensitivity requirements if applicable.

Crystals Selection Notes

Select this component when a standard HC-49/US footprint is required but board space is limited due to its low-profile profile. The 18 pF load capacitance aligns with common microcontroller oscillator inputs. Consider the 25 Ohm ESR value for driver strength matching. Verify that the ±50 ppm stability meets the system's jitter and timing budget constraints.

Crystals Part Context

This part belongs to the ABLS-LR series, representing Abracon's low-profile crystal lineup. It serves as a surface-mount alternative to traditional through-hole crystals, maintaining the familiar dimensions of the HC-49/US case while reducing overall height. This series is widely used in general-purpose timing applications where reliability and size efficiency are prioritized.

Crystals Replacement Considerations

Direct substitutes include the ABLS-4.433619MHZ-B4-T from the same manufacturer family. Other compatible options may include crystals from competitors offering identical 4.433619 MHz frequency, 18 pF load capacitance, and HC-49/US package dimensions. Always verify electrical parameters before substitution.
