Crystals Procurement Notes

Verify the specific suffix 'MAHJ' against official datasheets to confirm the 20 pF load capacitance and 40 Ohm ESR values. Ensure the 5.0x3.2 mm footprint matches the PCB layout requirements. Confirm RoHS3 compliance status directly with the manufacturer or authorized distributors prior to final procurement decisions.

Crystals Selection Notes

Select this component when a 13.56 MHz fundamental frequency is required for RFID or NFC applications. The 20 pF load capacitance must match the circuit design specifications. Consider the 40 Ohm ERS for impedance matching calculations. Verify that the -40°C to +85°C temperature range meets the operational environment constraints.

Crystals Part Context

This part belongs to the TXC 7M series of surface-mount crystals. It shares the standard 13.56 MHz frequency common in contactless communication technologies. The 7M series typically offers various load capacitance options within the same physical footprint family, allowing for design flexibility while maintaining consistent mechanical integration parameters.

Crystals Replacement Considerations

Public confirmed substitute: 7B-13.560MAAJ-T. Note that the substitute has a different load capacitance (18 pF vs 20 pF) and operates within a narrower temperature range (-20°C to +70°C). Circuit re-verification is required before substitution.
