KEMET SS21V-050360 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The KEMET SS21V-050360 is a 2-line common mode choke designed for power line filtering applications. This through-hole component features 36 mH inductance at 1 kHz with a 500 mA maximum current rating and 2.4 Ohm DC resistance. The part is currently active in production and widely used in EMI/RFI suppression circuits requiring through-hole mounting.

Substitute parts are identified when component availability is limited, inventory constraints exist, or design specifications allow for alternative inductance values within the same electrical and mechanical parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the SS21V-050360 and SS21V-R050540 are active production components from KEMET's SS series. Both parts carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for industrial and commercial applications.

The primary difference between these parts is inductance value: 36 mH versus 54 mH at 1 kHz. All other electrical parameters—current rating, DC resistance, voltage rating, and operating temperature range—are identical. Physical footprint and mounting configuration are identical, ensuring direct PCB compatibility.

Selection between these parts depends on circuit design requirements for inductance value. Both parts are suitable for power line filtering applications where through-hole mounting and 2-line common mode choke functionality are specified.
