Some folks have been having trouble finding part number KMS-1102NL, which is described as a “Network Transformer” in resources that I could find.
As far as drop-in replacements, we have the following options which should work:
553-1532-1-ND, 553-1536-1-ND, 553-2208-1-ND, 553-1759-1-ND.
One thing to note on the “Network Transformer” name is that this description most closely aligns with our Pulse Transformers category. Specs for the original part can be found here for comparison: KMS-1102NL
Please review the datasheets to ensure the alternative will work for your application.
