TPS2549: the difference between TPS2549RTER and TPS2549IRTERQ1

Our customer  is using TPS2549RTER for their products, but they can't get TPS2549RTER.

Is it possible to direct replace TPS2549RTER with TPS2549IRTERQ1?

Hi Kura,

Chuck will be out of office this week and will provide additional feedback once he returns next week.

Thank you,

Thank you for your reply.

Please let us know about Operating junction temperature and Description of Op Temp  of each device.

Description of Operating junction temperature

TPS2549IRTERQ1

Description of Op Temp (°C) PACKAGE OPTION ADDENDUM  (Addendum-Page 1)

TPS2549RTER (Addendum-Page 1)

TPS2549IRTERQ1

 I think Description of Op Temp (°C)  means ambient temp.

Is Op Temp (°C) of TPS2549RTER (-40 to 125) Clerical error ?

Kura,

The Operating Junction temperature specifies the range of  device junction temperature that the device will meet all specifications

The Op temperature is the ambient temperature that the device will operate at.

I do believe that the TPS2549IRTERQ1 Op temp, should be -40 to 125C and this is a clerical error in the spec, but I need to confirm this internally.
