Crystals Procurement Notes

Verify the specific suffix designation against manufacturer documentation to confirm package type and tolerance class. Ensure the load capacitance requirements of the target oscillator circuit align with the 20 pF specification. Confirm that the operating temperature range meets the environmental constraints of the final assembly before procurement.

Crystals Selection Notes

Select this component when a fundamental mode crystal with moderate stability is required for cost-sensitive designs. The HC-49/US package offers robust mechanical handling for through-hole manufacturing processes. Consider the ±30 ppm tolerance relative to system clock accuracy requirements and verify compatibility with the driving circuit's impedance matching needs.

Crystals Part Context

This part belongs to the YIC general-purpose crystal lineup designed for consumer electronics and industrial control applications. The HC-49/US form factor is widely adopted for its reliability and ease of automated placement. It serves as a primary timekeeping element in systems requiring basic frequency generation without high-precision oven-controlled specifications.

Crystals Replacement Considerations

Substitutes must match the 16 MHz frequency, 20 pF load capacitance, and HC-49/US package dimensions. Verify ESR compatibility and temperature range alignment. Cross-reference manufacturer datasheets for pinout and electrical parameter equivalence to ensure functional interchangeability in existing circuits.
