SS11VL-04350 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SS11VL-04350 is a 2-line common mode choke manufactured by KEMET, designed for power line filtering applications. This through-hole component operates at 35 mH inductance at 1 kHz with a maximum current rating of 400 mA and DC resistance of 2.6 Ohm. The part is ROHS3 compliant and rated for 250V AC operation across an operating temperature range of -25°C to 120°C. As an active product with established inventory availability, equivalent and substitute parts may be required for design flexibility, supply chain optimization, or specific application parameter adjustments.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS11VL-04350 are qualified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Filter Type: Power Line
• Number of Lines: 2
• Current Rating (Max): 400 mA
• Voltage Rating - AC: 250V
• Operating Temperature Range: -25°C ~ 120°C
• Mounting Type: Through Hole
• Package / Case: Vertical, 4 PC Pin
• RoHS Status: ROHS3 Compliant

Variable Parameters Allowing Substitution:

• Inductance @ Frequency: 25 mH to 52 mH @ 1 kHz
• DC Resistance (DCR) (Max): 2.6 Ohm to 2.8 Ohm

The identified substitute parts maintain all primary compatibility criteria while allowing variation in inductance and DC resistance within acceptable engineering tolerances for power line common mode choke applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SS11VL-04350, SS11VL-R04520, and SU10VFC-R04250—are active products manufactured by KEMET with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on inductance requirements specific to the application:

SS11VL-04350 (35 mH @ 1 kHz): Primary specification with 2.6 Ohm DCR. Suitable for applications requiring mid-range inductance filtering.

SS11VL-R04520 (52 mH @ 1 kHz): Higher inductance variant within the same SS11VL series, maintaining identical DCR of 2.6 Ohm and physical dimensions. Appropriate for applications requiring enhanced filtering at the expense of higher inductance.

SU10VFC-R04250 (25 mH @ 1 kHz): Lower inductance option from the SU10VF series with slightly elevated DCR of 2.8 Ohm and reduced physical dimensions (18.00mm x 15.50mm x 15.00mm height versus 22.00mm x 14.50mm x 19.50mm height). Suitable for space-constrained applications or those requiring lower inductance filtering.

All parts maintain 400 mA current rating, 250V AC voltage rating, and -25°C to 120°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can SS11VL-R04520 directly replace SS11VL-04350 in my circuit?

A: SS11VL-R04520 shares identical electrical ratings (400 mA, 250V AC, 2.6 Ohm DCR) and physical package specifications with SS11VL-04350. The primary difference is inductance: 52 mH versus 35 mH at 1 kHz. Direct replacement is possible only if the application circuit tolerates higher inductance filtering characteristics.

Q: What are the physical dimension differences between these substitute parts?

A: SS11VL-04350 and SS11VL-R04520 share identical dimensions: 22.00mm L x 14.50mm W x 19.50mm height. SU10VFC-R04250 has reduced dimensions: 18.00mm L x 15.50mm W x 15.00mm height. This makes SU10VFC-R04250 suitable for space-constrained PCB layouts.

Q: Are all three parts RoHS compliant?

A: Yes. SS11VL-04350, SS11VL-R04520, and SU10VFC-R04250 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: How does DC resistance affect substitution?

A: SS11VL-04350 and SS11VL-R04520 both specify 2.6 Ohm maximum DCR. SU10VFC-R04250 specifies 2.8 Ohm maximum DCR. This 0.2 Ohm difference may impact power dissipation in high-current applications. Verify thermal performance requirements before substitution.

Q: What is the inductance range across these substitute parts?

A: Inductance values at 1 kHz range from 25 mH (SU10VFC-R04250) to 52 mH (SS11VL-R04520), with SS11VL-04350 at 35 mH. Selection depends on the specific EMI filtering requirements of the power line application.

Q: Are all parts available in the same packaging format?

A: Yes. All three parts use Vertical, 4 PC Pin through-hole packaging, ensuring mechanical compatibility with standard PCB footprints designed for 2-line common mode chokes.
