When I search for the specific part number I can't find anything - But honestly I am out of my depth and not sure 100% in what I am looking for


Can anyone help me find one.

Preface your search with "transistor"

Dual channel LNA module

The squiggly T is an identifier for Teccor Electronics. Teccor No longer exists as I believe it was bought out by Littelfuse.

This link is to the datasheet.

Give me a few minutes and I'll see what is available for a Littelfuse alternate or if there is any other alternate.

I did not find a direct replacement for the S1055M at Littelfuse. It appears they have ditched their 100v and 200v (Vdrm/Vrrm) and the lowest they go is 400v. So long as the other parametrics check out, the increase in Vdrm is gooder :)

The part is S4055M and is in-stock/available at mouser.com . Here is a link to the datasheet so you can compare parametrics (to the original datasheet):

NTE was my other thought. However their cross-reference tool appears to be a program that one needs to download and then register. I need to tend to some other things but if you want me to look at NTE just holler and I'll do so.

Thank you I will check it out

FYI, This is what pops up as a Teccor S1055M replacement from NTE: NTE5539
