Due to the long lead times for plastic FPXLF parts?
We, at Fox, thought you might be interested in alternatives
that do not require that you change your circuit board?
Alternative is fully RoHS Compliant / Pb Free – FPXLF uses Exemption 7a
The FPXLF layout is one of the earliest conversions from Thru-Hole,
to surface mount. As such, the 2 terminations on the right are not
used for anything in the circuit. The pads are there only to provide
additional mechanical adherence to the circuit board.
The circuit only uses the 2 pads
on the left. The pads on the right
can remain empty and the circuit
will work normally.

Fox Pad Layout
Even if you are using one of the competitor recommended layouts, it
is only the 2 pads on the left. If an alternative will fit on the smaller
Fox recommendation, it will fit on the competitor’s layout.

For Frequencies above 8MHz *1* , there is an alternative, the Fox model FQ5032A.
It is available with 25°C accuracy of ±20ppm, ±25ppm, ±30ppm, ±50ppm, or ±100ppm.
And the same values for stability between -20°C & +70°C.
For -40°C to +85°C, it is available at ±30ppm, ±50ppm, or ±100ppm.
More capable than the model FPXLF – and can be purchased at a lower cost!
And it fits very well on the active 2 pads of the model FPXLF.
