Here's the correct link

These are Teletype Part 181384 (88-108 uF) as used in the M33 and M32.

Also suitable as a substitute for 162072 (33-103 uF) used in 0.025 HP miniature motor M28 mini-TD and mini-ROTR equipment (I just cut the wire leads short and soldered to them).

While not the correct capacitor 122245 (43-48uF) used with the 1/20 HP M28 KSR, RO, TD, and reperf motor, I have had no problem using it for that - most importantly it fits in the LMU where the original is.

I think Tom says that this capacitor did not work for the larger 1/12 HP motor used in his 28ASR. That cap is 160299 (226 uF)

Tedds.com has sku 2020000083 which physically fits in the belly of the motor assembly. It is electrically the next larger in capacitance, but works fine in the 1/20 HP and I think the correct size for the 1/12 HP.
The other thing is leads instead of solder lugs. It actually has a 181xxx Teletype part number on it .

IIRC a search on their site for the cap p/n for either the 1/20 or 1/12 HP will get an exact replacement ar 4x price.
