X2540-A0NIB matches key 2.54mm shunt ratings but needs A0/A1 review.
X2541-A1NIB is a 2.54mm, 2-pin shunt jumper rated 3A and 1000VAC. Alternatives need drawing and plating review.
Current and voltage match on best candidates, but contact resistance is often missing.
Pitch matches, but body dimensions are not checked.
Passive jumper; no firmware interface.
Lifecycle data is incomplete for some candidates.
No pin-compatible replacement is verified from the indexed fields.
Start with HY-2541-A1NIB, then check X2540-A0NIB if A0/A1 body differences are acceptable.
Unverified package drawing, pinout and plating stack.
