Customer has a request for replacement parts of competitors below.
manufacturer : Will semi
We searched for a replacement product, but we did not find a suitable part, so we will contact you.
1. For the WAS4729QB our closest part is the TS5A22362 - a 2 channel 2:1 switch that can swing negative signals (Can Pass VDD - 5.5V) and has a low on resistance at 3.6V (0.61 Ohms typical). It isn't P2P as we don't have this part in a QFN package - but the DSBGA package (YZP Package Code) provides a similarly sized footprint so you wouldn't have to sacrifice space savings by using this part.
2. For the WAS3157D we have two options that could be used - but they aren't pin to pin - we do not have a p2p match with these characteristics. But the two options I see are:
i) Option 1: TMUX1237/TMUX1247 these parts offer lower on resistance but a slightly higher leakage current and a slightly smaller bandwidth at 250MHz it is available in the SC-70 package.
ii) Option 2: TMUX1119 - this is a precision part and it offers lower On resistance and leakage currents than the WAS3157D but it does also have a bandwidth of 250MHz.
However I'd like to ask what the customers are looking into these parts for - what are the features they are wanting to keep because we do have a range of parts that may work better for the application if all the features of the will semi parts are not needed.
Please let me know!
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
