OptoMOS Relay

[Rajinder]

Hi,
I am looking at an alternative Opto MOSRelay, used for electronic switching - 12V supplies. Both are SOP4 packages, with the same pinout. The comparison has shown the following:
1.
The new part has faster turn on / off times i.e. on - 1ms, off - 0.5ms compared with the older relay i.e. on and off both are 10ms.

2. Vf of LED is 1.2V (old) to 1.4V for alternative (typical values)

3. On resistance is 10 ohms compared to 16 ohms on the older part.

4. Output capacitance 5pF -older device and 20pF in the newer device.

I cant see the forward voltage being an issue. Not sure about the other specs. Isolation is 1500V rms for both.

Is there any issues associated? Or parameters that may be important.

Any help would be appreciated. Thanks.

What was your original type? (compared to your Opto MOSRelay?)
It would be better for us to know the two different part numbers, and/or application.
The primary consideration I look at when I'm comparing components, is their semiconductor-material compatibility.
Is your circuit MOS compatible?

I will send you the part numbers.
