I am trying to repair sewing machine by replacing a safety capacitor that burned up. I am not at all sure how to find an equivalent capacitor. Advice or links to an appropriate product would be appreciated.

capacitor

info from capacitor body:

RIFA 40/085/56 GPC
PME 271 M 610
250V~MP fo=4,9 Mhz X2

  • \$\begingroup\$ A straight 2.7 uF X2 capacitor should be easy to find. \$\endgroup\$ – winny Aug 17 '18 at 17:45
  • \$\begingroup\$ Type the P/N on the cap into Octopart.com \$\endgroup\$ – EE_socal Aug 17 '18 at 17:48
  • \$\begingroup\$ @user: Why do you call this a "safety capacitor"? It's there to filter out noise and/or to reduce sparking and electromagnetic interference. \$\endgroup\$ – Transistor Aug 17 '18 at 17:48

    \$\begingroup\$ @Transistor Because of its X2 rating. \$\endgroup\$ – Adam Lawrence Aug 17 '18 at 17:53

The Rifa legacy and new Kemet codes are as follows: -

Here's the datasheet. Part available from Farnell most likely or the modern Kemet version.

It's a PME271M-40/085/56 0.1uF X2 safety capacitor. You can buy a direct replacement from Radwell International (scroll down to "NEVER USED Surplus Level 2") for $0.85 a pop plus shipping.

You could also order pretty much any one of these from Digi-Key.

Here's another direct replacement on Digi-Key (made by KEMET) for $1.82 plus shipping.

That RIFA part series has been a problem child for many years, so you may not want a direct replacement. However, any X2 capacitor of the same value (more or less) will do just fine. Many people make them and any distributor will sell them. You might even find them on Amazon.
