SIT3088EEUA
SIT
Needs validationlow risk
A strong alternative with matching package, temperature range, and bus load, plus a wider supply voltage range and higher data rate.
Best Alternatives to WS3080
The WS3080 is a robust 5V, half-duplex RS-485 transceiver in an MSOP-8 package, notable for its 1/8 unit load that supports up to 256 nodes. Several alternatives exist, with SIT3088EEUA being a strong candidate for a drop-in replacement.
AI replacement insight
Electrical riskhigh
Mismatch in bus unit load can cause network failure if the node count exceeds the substitute's limit.
Package risklow
All viable candidates use the same MSOP-8 package, but pinout must always be verified.
Sourcing riskmedium
Some alternatives may have different regional availability or lifecycle status.
Can it be replaced directly?
Direct replacement for WS3080 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
SIT3088EEUA is the strongest candidate, matching or exceeding all key specifications of the WS3080. It offers a wider supply voltage range and higher data rate while maintaining the same package, bus load, and temperature range.
Main risk
The primary risk when substituting the WS3080 is mismatch in bus loading (number of nodes supported). Several alternatives support far fewer than the target's 256 nodes.
