Crystals Procurement Notes

This component is officially classified as obsolete and is no longer manufactured by TXC Corporation. Procurement should focus on verified substitute part numbers such as the 7M-27.000MAHE-T. Buyers must confirm availability through authorized distributors or secondary market suppliers, as standard production channels are closed. Verify datasheet revisions and physical dimensions before integration.

Crystals Selection Notes

Select this component only if legacy compatibility is required. For new designs, consider the active 7M-27.000MAHE-T which shares similar electrical parameters including 27 MHz frequency, 12 pF load capacitance, and 60 Ohm ESR. Ensure the replacement matches the 4-SMD footprint and meets the -40°C to +85°C temperature specification.

Crystals Part Context

The 7S series represents a line of surface mount crystals from TXC Corporation. This specific model is part of the broader portfolio of timing components used in compact electronic devices. The 'S' designation typically indicates a specific package style within the manufacturer's catalog, now superseded by newer generations like the 7M series.

Crystals Replacement Considerations

The 7M-27.000MAHE-T is a confirmed public substitute. It maintains the same 27 MHz frequency, 12 pF load capacitance, and 60 Ohm ESR. Verify that the 7M series package dimensions are compatible with the existing PCB footprint intended for the 7S series.
