Crystals Procurement Notes

This component is officially designated as obsolete by the manufacturer and is no longer in production. Sourcing new units from authorized channels is not possible. Procurement efforts should focus on verifying the authenticity of existing surplus stock or identifying approved replacement parts that meet identical electrical and mechanical specifications to ensure supply chain continuity.

Crystals Selection Notes

Designers requiring this specific frequency and package must evaluate alternative components due to the discontinuation status. Selection criteria should prioritize matching the 12 MHz frequency, 18 pF load capacitance, and HC-49/S form factor. Cross-referencing datasheets for equivalent performance metrics is essential to maintain system timing integrity when substituting this end-of-life part.

Crystals Part Context

The 7B12000046 belongs to the broader category of quartz crystals manufactured by TXC Corporation. It represents a legacy surface-mount solution within their portfolio, distinct from their active oscillator lines. The HC-49/S package is a widely recognized industry standard, facilitating compatibility with various printed circuit board layouts designed for through-hole or compact surface-mount implementations.
