Crystals Procurement Notes

Verify the specific suffix 'IAR' against the manufacturer's current datasheet to confirm pinout and packaging details. Ensure compatibility with the target circuit's load capacitance requirements. Check for RoHS compliance status as per the latest environmental declarations. Confirm availability through authorized distributors given potential supply chain variations.

Crystals Selection Notes

Select this component when a 50 MHz reference with tight ±10ppm stability is required. The 60 Ohm ESR must match the oscillator circuit design. The 2.00mm x 1.60mm footprint suits space-constrained PCB layouts. Verify that the -20°C to 70°C temperature range meets the operational environment constraints.

Crystals Part Context

This part belongs to the CTS 402 series of crystals, which are characterized by their small 4-SMD no-lead form factor. The series offers various frequencies and load capacitances, providing flexibility for different embedded system designs while maintaining consistent physical dimensions for automated assembly.

Crystals Replacement Considerations

Direct substitutes include other 50 MHz crystals with identical 4-SMD 2.0x1.6mm packages, 10ppm stability, and compatible ESR values. Cross-reference with CTS 402F50012IJR or similar variants from other manufacturers offering fundamental mode SMD crystals with matching electrical parameters.
