Title: Alternative for IDT XLH536026.000000I Crystal Oscillator
Post by: MikerVee on May 10, 2017, 03:13:36 PM

Hi Daniel,

We're doing a new small production run of the Miniscope.
Seems like all usual suppliers (Farnell, Mouser, Digi-Key etc.) have run out of 26MHz oscillators in size 5.0 x 3.2 mm.
Do you happen to know any sources who have these, or suitable replacements, on stock?

Best,
Mike

Hi Mike,
Well it looks like that oscillator is being discontinued. Give me a day or two and I will find a replacement part.

Here are a couple options:

https://www.digikey.com/product-detail/en/ecs-inc/ECS-3225S33-260-FN-TR/XC2222CT-ND/6578529
This oscillator has a smaller package size but its footprint should match well enough to the current footprint on the PCB to work just fine. You can double check the specs yourself and let me know what you think.

This may also work but I haven't looked through the entire data sheet yet.

Thanks for your quick reply, Daniel.

I hadn't thought of using a smaller one as a replacement.

For now, I selected the ECS-3225S33-260-FN-TR.

Once the PCBs are tested, I'll let you know how it worked out.

Best,
Mike
