SS21V-R110100 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SS21V-R110100 is a 2-line common mode choke manufactured by KEMET, designed for power line filtering applications in through-hole configurations. This component provides 10 mH inductance at 1 kHz with a maximum current rating of 1.1A and operates across a temperature range of -25°C to 120°C. The part is currently active in production status and maintains ROHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, allowing for component interchangeability in circuit designs where specific inductance and current characteristics are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS21V-R110100 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Number of Lines: 2
• Mounting Type: Through Hole
• Package / Case: Vertical, 4 PC Pin
• Voltage Rating - AC: 250V
• Operating Temperature Range: -25°C ~ 120°C
• Filter Type: Power Line
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Inductance @ Frequency: May vary based on application tolerance
• Current Rating (Max): Must equal or exceed circuit requirements
• DC Resistance (DCR) (Max): May vary within acceptable circuit loss parameters
• Physical Dimensions: May vary within board layout constraints

The SS11V-11050-CH qualifies as a parametric equivalent based on matching all mandatory criteria while presenting different inductance (5 mH vs. 10 mH) and DCR (400 mOhm vs. 450 mOhm) values. This substitution is valid for applications where the lower inductance value and reduced DC resistance are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the SS21V-R110100 and SS11V-11050-CH are active production components manufactured by KEMET within the SS series common mode choke family. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Selection between these parts is determined by circuit inductance requirements. The SS21V-R110100 provides 10 mH inductance, suitable for applications requiring higher filtering attenuation at 1 kHz. The SS11V-11050-CH provides 5 mH inductance with lower DC resistance (400 mOhm vs. 450 mOhm), suitable for applications where reduced power dissipation is prioritized or where lower inductance values satisfy filtering specifications.

Both components support identical current ratings (1.1A maximum), voltage ratings (250V AC), and operating temperature ranges (-25°C to 120°C). Physical dimensions differ slightly; board layout constraints may influence part selection based on available mounting space.

Frequently Asked Questions (FAQ)

Q: Can the SS11V-11050-CH replace the SS21V-R110100 in any application?

A: The SS11V-11050-CH qualifies as a substitute only in applications where 5 mH inductance satisfies circuit filtering requirements. The lower inductance value provides reduced attenuation compared to the 10 mH specification of the main part. Circuit analysis must confirm that the substitute inductance value meets application performance criteria.

Q: What is the difference in DC resistance between these parts?

A: The SS21V-R110100 has a maximum DC resistance of 450 mOhm, while the SS11V-11050-CH has a maximum DC resistance of 400 mOhm. The substitute part exhibits 50 mOhm lower resistance, resulting in reduced power dissipation in the component. This difference may be advantageous in thermal-constrained applications.

Q: Are the physical dimensions compatible with the same PCB footprint?

A: The parts have different dimensions. The SS21V-R110100 measures 0.807" L x 0.650" W x 0.965" H, while the SS11V-11050-CH measures 0.866" L x 0.571" W x 0.886" H. Board layout verification is required to confirm that the substitute part fits within available mounting space.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the SS21V-R110100 and SS11V-11050-CH are ROHS3 compliant and REACH unaffected. Both parts carry identical regulatory classification (ECCN: EAR99, HTSUS: 8504.31.4065).

Q: What is the current rating for both parts?

A: Both parts have an identical maximum current rating of 1.1A. Current capacity does not differentiate these components.

Q: Can these parts be used interchangeably in power line filtering applications?

A: Interchangeability is limited to applications where the inductance difference (10 mH vs. 5 mH) does not impact circuit performance. Power line filtering effectiveness depends on inductance value; applications requiring specific attenuation characteristics must use the part with matching inductance specifications.
