The difference between LTC3309BJ and LTC3309BH

Question

Hi, 
 I'm a DFAE in Japan. Our customer doesn't understand the spec difference between LTC3309BJ and LTC3309BH. Could you help us the answer? 
 
 Regards, 
 Hiroyuki

My explanation same goes with H & J. The J part probably offer improvements on the manufacture side and/or more robust operation compared to the 'older' part which is the H part. You can still choose either part since they still have the same operating temperature and operation.

Hello, 
 LT parts which have a letter behind their number code (like A, B or C) are pin compatible. The changes mostly just offer improvements and/or more robust operation compared to the 'older' part.
