Crystals Procurement Notes

Verify the specific suffix designation against official Epson documentation to confirm exact frequency tolerance and packaging specifications. Ensure compatibility with existing circuit load capacitance requirements before integration. Check current manufacturing status as certain variants may be obsolete or subject to supply constraints. Confirm RoHS compliance details if required by project regulations.

Crystals Selection Notes

Select this component when a 4 MHz fundamental frequency with ±50 ppm stability is required. The low ESR characteristic makes it suitable for circuits sensitive to noise or requiring efficient drive levels. Consider the 4-SOJ package dimensions for footprint availability on the target PCB layout. Validate that the operating temperature range meets the environmental conditions of the final application.

Crystals Part Context

This part belongs to the Epson MA-505 series of surface-mount crystals. The series offers various frequency options within the MHz range using fundamental mode operation. The 'PURE SN' designation indicates specific material or processing characteristics distinct from other variants in the lineup. It serves as a passive timing element replacing older through-hole technologies in modern compact designs.

Crystals Replacement Considerations

Direct substitutes include other Epson MA-505 variants with matching 4 MHz frequency and similar package dimensions. Cross-reference load capacitance and ESR values to ensure electrical equivalence. Verify that alternative components support the same operating temperature range and mounting style for seamless integration.
