Part Number: LM111


Customer is saying they have in their 15-yr old BOM a part marked LM111FK (without the "B"). However, upon checking the part marking tool and material information tool, there seems to be no LM111FK available.

(1) May I ask if you have any information regarding the differences of these two?

(2) Also, may I know what "B" stands for?

Thank you!

  • Hello Elisha,

    The "B" indicates the product is military grade and goes through the additional testing for mil grade products.   Otherwise the two products are the same.
