SS20H-08100 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SS20H-08100 is a 10 mH Common Mode Choke (CMC) manufactured by KEMET, designed for power line filtering applications. This through-hole component operates at 800mA maximum current with a DC resistance of 660mOhm and is rated for 250V AC operation across a temperature range of -25°C to 120°C. The part is Active in product status and ROHS3 compliant. Equivalent and substitute parts are identified when design requirements necessitate different inductance values, physical dimensions, or inventory availability while maintaining compatibility with the 2-line configuration, 800mA current rating, and through-hole mounting specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS20H-08100 are qualified based on the following critical parameters that must remain constant or within acceptable tolerance:

Fixed Parameters (Must Match):

• Number of Lines: 2
• Current Rating (Max): 800mA
• Voltage Rating - AC: 250V
• Operating Temperature Range: -25°C ~ 120°C
• Mounting Type: Through Hole
• Package / Case: Vertical, 4 PC Pin
• Series: SS
• Manufacturer: KEMET
• RoHS Status: ROHS3 Compliant

Variable Parameters (Allowed to Differ):

• Inductance @ Frequency: 10 mH, 12.5 mH, or 25 mH @ 1 kHz
• DC Resistance (DCR): 660mOhm to 750mOhm
• Physical Dimensions: Length, width, and height vary with inductance value

The two identified substitute parts maintain all fixed parameters while offering alternative inductance values and corresponding dimensional changes. Selection between the main part and substitutes depends on the specific inductance requirement of the application circuit.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SS20H-08100, SS11V-R08125-CH, and SS24V-R08250-CH—are Active products manufactured by KEMET with identical compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99 ECCN classification). Selection between these parts is determined by the required inductance value for the application:

SS20H-08100 (10 mH @ 1 kHz): Select when the circuit design specifies 10 mH inductance. This part offers the lowest DC resistance (660mOhm) and the most compact footprint (22.00mm x 22.00mm x 18.50mm height).

SS11V-R08125-CH (12.5 mH @ 1 kHz): Select when the circuit design specifies 12.5 mH inductance. This part provides a narrower width (14.50mm) compared to the main part, though with slightly increased height (22.50mm) and DC resistance (740mOhm).

SS24V-R08250-CH (25 mH @ 1 kHz): Select when the circuit design specifies 25 mH inductance. This part accommodates higher inductance filtering requirements with a larger footprint (26.00mm x 19.00mm x 31.50mm height) and DC resistance of 750mOhm.

All parts maintain the 800mA current rating, 250V AC voltage rating, -25°C to 120°C operating temperature range, and through-hole vertical 4-pin package configuration. Physical space availability on the PCB and the specific inductance filtering requirement are the primary factors in part selection.

Frequently Asked Questions (FAQ)

Q: Can SS11V-R08125-CH or SS24V-R08250-CH be used as direct replacements for SS20H-08100?

A: Direct replacement depends on the circuit design specification. If the design requires 10 mH inductance, only SS20H-08100 is appropriate. If the design allows for 12.5 mH or 25 mH inductance, the respective substitute parts are compatible. All three parts share identical electrical ratings (800mA, 250V AC, -25°C to 120°C) and mounting configuration.

Q: What are the physical space implications when substituting between these parts?

A: The three parts have different footprints. SS20H-08100 measures 22.00mm x 22.00mm with 18.50mm height. SS11V-R08125-CH is narrower at 22.00mm x 14.50mm but taller at 22.50mm. SS24V-R08250-CH is the largest at 26.00mm x 19.00mm with 31.50mm height. PCB layout must accommodate the selected part's dimensions.

Q: Are there compliance or regulatory differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 under ECCN. They share identical regulatory and environmental compliance status.

Q: How do DC resistance values differ, and does this affect part selection?

A: SS20H-08100 has 660mOhm DCR, SS11V-R08125-CH has 740mOhm, and SS24V-R08250-CH has 750mOhm. Higher inductance values correlate with slightly higher DC resistance. The difference is within 90mOhm across the range. Selection should be based on the required inductance value; DCR differences are secondary considerations unless the application has specific power dissipation constraints.

Q: Can these parts be used interchangeably in the same circuit board design?

A: No. While all parts are mechanically and electrically compatible in terms of current, voltage, and temperature ratings, they cannot be interchanged without circuit redesign because they provide different inductance values. The circuit design must specify which inductance value is required.
