I have compiled a list of THT integrated magnetics pin compatible preferred parts I wish to share. Symmetrical transformer with caps & 75 Ohms. If you have any more to add – or remove from the list, please post here: This is a good site for alternate parts.

Thank you for your good information. ![:heart_eyes:](https://emoji.discourse-cdn.com/twitter/heart_eyes.png?v=12) I will review this. You will help a lot of people. Scott. ### Reply 3 by jnewcomb, 2017-10-03 I can’t work out how to edit my first post, so I’ll append info here… So, I have a working design… see link below. J0011D21BNL → Double check the footprint of the device… I think its different… Price… I have chosen the J0011D21BNL from PULSE - because we already use it on another product. Its a good brand and can be purchased from reliable sources for around 1.10 USD. (Check the footprint of the connector) So, if you have a low cost easy to find device, please share here… Thanks… [Layout / Schematic review - reference design](https://forum.wiznet.io/t/topic/3131) [W5500](https://maker.wiznet.io/c/tcp-ip-chip/w5500/18) > Please can someone review and suggest any improvements?? I will follow up this post with the final design and or confirmation of if it worked or not, it should serve as a good reference design. Comments: I have clamped the TX/RX pairs to AGND and 3V3A using IC21 IC22. Its a very noisy environment… I’m not sure if I have clamped the RXP/RXN correctly… Should C106 and C107 be on the LEFT hand side of the clamp?? Don’t copy anything here until I have has a chance to follow up… [\[image\]](https://maker.wiznet.io/forum_uploads/wiznet/original/2X/6/6ae8d93cf2456d1fc13baf2b0785d6718eb9db2a.png) NEW R… ### Reply 4 by mcpat, 2024-04-22 I know the topic is old, but would this RJ45 jack fit, I am planning to make a POE application: [Link-PP LPJ4320GENL](https://www.link-pp.com/sale-38191750-lpj4320genl-10-100-base-t-rj45-poe-magnetic-jacks-tab-down-green-yellow-led.html) You can see the circuit in the [datasheet](https://www.l-p.com/file/datasheet/lpj4320genl.pdf) I compared with the reference design [here](https://docs.wiznet.io/img/products/w5500/w5500_sch_v110_use_mag_.pdf) and I think it’s correct. ![LPJ4320GENL](https://maker.wiznet.io/forum_uploads/wiznet/original/2X/5/552f0311cb7caf50f5729b6d41c0c59dc9e84071.png) Thank you in advance! Patrick ### Reply 5 by jnewcomb, 2024-04-22 Hi mcpat, The LPJ4320GENL Looks good. Note: The connector I used does not have the 4 x 1nF parts integrated into the connector (as shown in your screenshot) --- PULSEJACK part - Clarification… J0011D21BNL can’t be used with the reference schematic (and my supplied schematic) as Pins 2-4 are shuffled. If you use it, you must change your schematic accordingly. ### Reply 6 by mcpat, 2024-04-23 (in reply to reply 5) [@jnewcomb](https://maker.wiznet.io/u/jnewcomb) Thank you very much! So I give it a try. It will take some time because it’s my hobby, but after testing I will come back and will give a feedback. --- Source: https://maker.wiznet.io/forum/12293
