Physically it will probably fit into the ports on each end. And most likely will work.
One caution: from the description: "Designed to meet all HDMI standards....." "Designed to" does not necessarily mean it will actually work.
The reason for my caveat is that the pinouts (basically the internal end to end wire connections) need to match accepted standards. However, if some proprietry configuration has been used by one device or the other then the connection will not or only partially work. Google "Composite to HDMI pinouts" for examples. Do not let all that overwhelm you.
Substandard, low quality cables even if they match the standard, may not work.
Overall, such cables can generally be purchased locally so you could buy one and give the cable a try. Make sure that you can return the cable if necessary.
