Standard ubiquitous footprint for common mode choke?

[Faringdon]

Hi,
We need a ~1.5ASMD common mode choke for a 12V power rail.
This one does the job....but if it goes obselete/nil-sock, we've had it...

https://product.tdk.com/en/system/files?file=dam/doc/product/emc/emc/cmf_cmc/catalog/cmf_commercial_power_acp3225_en.pdf

...is there a particular range of these which has a standard, common, ubiquitous ,  ~1.5A, SMD footprint so we can replace if necessary, without a board respin?

Is there a standard footprint for these type of SMD common mode chokes....or does every manufacturer have their own custom one?..it seems like it

I used a TDK ZJYS-series part which also went obsolete, replaced with Bourns SRF 0905 series

there's probably no universal footprint for cm-chokes..

There seems to be an endless number of footprints for chokes and inductors. I have seen a few clients create a footprint mashup of a few similar ones so they have the option to chop and change a bit if required, typically they have footprints that let you get away with that kind of thing.

You'll find a bunch in very similar larger footprints like the 9x6mm Bourns one linked above, but at 3.2x2.5mm (1210) and that rating there doesn't seem to be much available apart from the TDK ACP3225.

You don't mention the filtering specs you need, but Wurth have one that might suit in 4.5x3.2mm (1812).

Murata had some similar small ones but I recall they went NRND.  Yeah, the DLW44 series - 4.0x4.0mm.  Looks like some new ones are coming to replace them.

So, I think the answer is no.  If you have the space then try go for a larger part or place multiple alternative footprints.  Or buy up big in advance.

Or buy custom.  Parts of that shape aren't too uncommon, good luck getting the attention of a big OEM like TDK or Murata of course but Coilcraft might do that.

Unfortunately their closest standard part doesn't offer quite the current rating,

so you may have to see what they're capable of, or choose a different part.

Looks like choosing a somewhat bigger part may be a good idea anyway, just for availability.  The smaller size may be pushing capability, and thus costing more than a relaxed design would.
