Crystals Procurement Notes

Verify the specific suffix 'E' against the manufacturer's official part number guide to confirm pin configuration and packaging details. Ensure the 8 pF load capacitance matches the host oscillator circuit requirements. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement specifications.

Crystals Selection Notes

Select this component when a 39 MHz reference is required with tight ±10 ppm stability constraints. The 8 pF load capacitance necessitates matching with compatible microcontroller or RF transceiver inputs. The 3.2x2.5mm package offers a balance between size reduction and mechanical robustness compared to smaller alternatives.

Crystals Part Context

This part belongs to the TXC 7M series, which specializes in ultra-thin sealed surface-mount crystals. The series targets miniaturized portable electronics, offering low EMI characteristics and high reliability. The 7M series provides various frequency options within the 10 MHz to 114 MHz range, catering to diverse wireless and digital interface standards.

Crystals Replacement Considerations

Direct substitutes include other 39 MHz crystals from the same 7M series family, such as 7M-39.000MAAE-T or 7M-39.000MAHE-T, provided they meet the identical 8 pF load capacitance and ±10 ppm stability requirements. Cross-brand replacements must match the 3.2x2.5mm form factor and electrical parameters.
