Part Number: LM2940-N

Dear Specialists,

My customer'd like to know the MSL level difference between LM2940T-5.0/NOPB and LM2940T-5.0/LF08.

I would be grateful if you could advise.

LM2940T-5.0/NOPB and LM2940T-5.0/LF08 are the same TO220 package.

Package drawing are almost the same. Accrding to the following thread, LM2940T-5.0/LF08 is straight lead.

On the other hand, MSL level is different.

LM2940T-5.0/NOPB is MSL1 and LM2940T-5.0/LF08 is MSL3.

Could you please let us know the reason.

I appreciate your great help in advance.

Best regards,
