Crystals Procurement Notes

Verify the specific ordering suffix K5 against official Epson documentation to ensure correct packaging and variant specifications. Confirm that the requested part matches the exact electrical parameters and physical dimensions required for the target application. Cross-reference the manufacturer's latest datasheet to validate current product status and availability before finalizing procurement orders.

Crystals Selection Notes

Select this component when a small form factor is critical for board space constraints. Ensure the circuit design accommodates the specified 10 pF load capacitance and 200 Ohm motional resistance. Verify that the operating environment remains within the -40°C to +85°C range to maintain frequency stability and reliability standards.

Crystals Part Context

This part belongs to the FA-118T series of crystal units from Epson Timing. The series covers frequencies from 24 MHz to 54 MHz, offering fundamental overtone options in a standardized ultra-miniature package. This specific model provides a 27.12 MHz output optimized for timing applications requiring precise frequency control in minimal space.

Crystals Replacement Considerations

Direct substitutes must match the 27.12 MHz frequency, 4-pin SMD footprint, and 1.6x1.2x0.35mm dimensions. Verify equivalent tolerance, stability, and load capacitance specifications. Consult Epson's official cross-reference guides for approved alternative part numbers within the same family.
