12290 MARS (Motors & Armatures) Run Capacitor, 50/5 uF, 440/370 V, Round, Dual Section
Comparison
3 numbers are listed with 12290 in the makers' documents. Each pair is read against the substitution rules: same duty, same section count, capacitance within the run band or the same start range, and a voltage rating equal to or above the original's. Each listing is its maker's and the reading is this site's. Neither is a guarantee that the two fit the same place.
- Industry number
- Packard names the MARS number its part stands in for.
- Same rating
- The MARS catalog lists both numbers at one rating.
