Oscillators Procurement Notes

This component is listed as obsolete and no longer manufactured by the producer. Verification of current availability through authorized distributors or alternative stock sources is required before procurement planning. Engineering teams should review the discontinuance notification and initiate design-in processes for replacement parts to ensure long-term supply chain stability and project continuity.

Oscillators Selection Notes

Select this part only if legacy compatibility is mandatory due to its obsolete status. For new designs, consider active MEMS oscillators from the same manufacturer family that offer similar electrical specifications and package dimensions. Ensure the selected replacement maintains the 1.000MHz frequency, LVCMOS output, and 1.6mm x 2.0mm form factor to preserve board layout integrity.

Oscillators Part Context

The EMRA46M2H-1.000M belongs to the EMRA series of programmable MEMS oscillators produced by Ecliptek, which was acquired by Abracon. This series focuses on providing compact, low-power clock solutions for portable and space-constrained electronics. The specific model represents a standard frequency variant within the broader portfolio of surface-mount timing devices.

Oscillators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements must be identified through official manufacturer obsolescence notices or distributor cross-reference tools.
