Replacement part number for i.MX8M EVK BOM (Crystal and RJ45 connector)

[calibronic]

Hi everyone,
I am going to design a custom board based on i.MX8M EVK.
First of all, I have checked i.MX8M EVK BOM in terms of market availability of components in Digkey, Mouser,..
I founded all the components except two components as below:
1. Y401,Y1201,Y1301,Y1401   -->   25MHZ 18pF 20ppm
2. J1201 -- >  CON 10 RJ45 SKT RA TH WITH G/Y LEDS 50MIL SP 611H -- 120L

- About the Crystal, What are the parameter are important ?
Could you please advice me about the replacement part number which are available in market ?

For the Crystal, the value is most important. Here you can use other company's Crystal, but the 25Mhz and 27Mhz the value you can not change. And the accuracy recommend to use the 20ppm.
