------Question for PSU1830 Please Put your question below------
Can I use PSU1830 as replacement for Aerovox z26s2820n22?
Thanks,
Jan
Hello Jan,
I was unable to find information on your part z26s2820n22, could you provide the electrical specifications for this to help me confirm if PSU1830 will work as an alternative?
Hi Rob, thats the tricky part. The pic I snapped from the cap is showing 200uF, but decomposition of the part number points to 20uF.
The part number Z26S2820N22 corresponds to a Cornell Dubilier (CDE) motor run capacitor with a capacitance of 20 µF and a voltage rating of 280 VAC. This type of capacitor is typically used in HVAC applications and other motor systems.
Key Specifications
According to product catalogs from Cornell Dubilier (CDE) and general vendor information, the key specifications for this series of capacitors are:
| Specification | Value | Source |
|---|---|---|
| Capacitance | 20 µF | |
| undefined | ---- | ---- |
| Voltage Rating (AC) | 280 VAC | |
| undefined | ---- | ---- |
| Frequency | 50/60 Hz | |
| undefined | ---- | ---- |
| Case Material | Aluminum (oil-filled) | |
| undefined | ---- | ---- |
| Terminal Type | 1/4" Male Quick-Connect | |
| undefined | ---- | ---- |
| Operating Temperature | -40°C to 70°C standard | |
| undefined | ---- | ---- |
| Life Expectancy | Rated for 60,000 hours duty | |
| undefined | ---- | ---- |
| Safety Certification | UL Recognized (E185318), UL-810 fault current protection | |
| undefined | ---- | ---- |
Looking at this datasheet it seems that the N after the 20 in this part number calls out a capacitance of 200 instead of 20 since the only options over 100uf have the N suffix while others have the M suffix. Although looking in our system further I was unable to find a 200uf 280v motor start capacitor as a possible substitute for you.

That seems right. I found in different datasheet that the N represents, N = Odd rating. So it is 200uF. Thank you for your help.

Note that the PSU1830 is an electrolytic type typically intended for intermittent use, while the device being replaced is a film type suited to continuous operation. Confusion over capacitance value aside, a substitution of that sort would not be recommended.
Normally-stocked listings for 200uF/ 280+V film caps can be found here.
