our supplier is using the TPS62110RSA at the moment. Because of delivery problems they want to replace it with a TPS62110QRSARQ1 which is the Q1 type or TPS62110MRSAREP which is the EP type. From the datasheet I can see they are almost indentical. In most cases the Q1 and EP types have more reserve.
Are they identical and only pre-sorted or are they physically different?
Can they be replaced directly or have we to do additional testing?
