My apologies. You are correct. To confirm that it really is OK now, this is the PCB footprint in EasyEDA: ![enter image description here][1] The pads have been selected so that they highlight in white to make it easy to read the pin numbers. The footprint is created so that the pads and silkscreen outline are on the top layer. When the pads in the image above are not selected like this, they are in red because they are on the top layer. The footprint is viewed from the side of the PCB on which the device is to be mounted i.e. looking down onto the top layer. This is a screenshot of Section 13.5 of the Murata Reference Specification from: http://www.murata.com/en-eu/products/productdata/8796777775134/ENFH0008.pdf?1496719828000 ![enter image description here][2] This shows the PCB footprint (lands) viewed from the side of the PCB on which the device is to be mounted i.e. looking down onto the top layer. Note that the land positions and dimensions in the EasyEDA footprint are the same as in the MuRata Sepcification. This is a screenshot of the device equivalent circuit in the same MuRata Specification: ![enter image description here][3] This is the (new) EasyEDA Schematic Symbol for the device: ![enter image description here][4] The pin 1 to 4 numbering and naming is correct to the device equivalent circuit in the same MuRata Specification. Pins 5 and 6 are also named CG so the numbering is arbitrary but conforms to that shown in Section 13.5 of the MuRata Specification.
