Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS11VL-R03820 are identified based on strict alignment of electrical and mechanical parameters within the common mode choke product category. The substitution logic is governed by the following key parameters:

Electrical Compatibility Criteria:

• Number of Lines: 2 (fixed requirement)
• Current Rating (Max): 300mA (fixed requirement)
• Voltage Rating - AC: 250V (fixed requirement)
• Operating Temperature Range: -25°C ~ 120°C (fixed requirement)
• Filter Type: Power Line (fixed requirement)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (fixed requirement)
• Package / Case: Vertical, 4 PC Pin (fixed requirement)

Variable Parameters Allowing Substitution:

• Inductance @ Frequency: 82 mH, 55 mH, or 37 mH @ 1 kHz
• DC Resistance (DCR) (Max): 4.1Ohm or 4.2Ohm
• Physical Dimensions: Variations permitted within through-hole vertical mounting constraints
• Manufacturer Series: SS or SU series

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and active product status. Substitution is valid when the circuit design tolerates the specified inductance and DCR variations.

Parameter Comparison

Engineering Selection Recommendations

SS11VL-03550 Selection Criteria: The SS11VL-03550 maintains identical electrical ratings (300mA, 250V AC, -25°C ~ 120°C) and mechanical form factor (22.00mm L x 14.50mm W x 19.50mm H) as the main part SS11VL-R03820. The inductance is reduced to 55 mH @ 1 kHz with equivalent 4.1Ohm DCR. This substitute is applicable when circuit design specifications permit lower inductance filtering. Both parts share the SS series designation and identical package configuration. ROHS3 compliance and active product status are maintained.

SU10VFC-R03370 Selection Criteria: The SU10VFC-R03370 provides the lowest inductance option at 37 mH @ 1 kHz while maintaining 300mA current rating and 250V AC voltage rating. Physical dimensions differ (18.00mm L x 15.50mm W x 15.00mm H), resulting in a more compact footprint. DCR is marginally higher at 4.2Ohm. This substitute is applicable when space constraints require reduced component height and circuit design tolerates the lowest inductance specification. The SU series designation indicates a different product line within KEMET's common mode choke portfolio. ROHS3 compliance and active product status are maintained.

Compliance Assurance: All three parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for power line filtering applications. Active product status across all options supports long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: What determines whether SU10VFC-R03370 can replace SS11VL-R03820? A: Substitution is valid when the circuit design accommodates the reduced inductance (37 mH versus 82 mH), accepts the slightly higher DCR (4.2Ohm versus 4.1Ohm), and fits the smaller physical dimensions (18.00mm L x 15.50mm W x 15.00mm H). All electrical ratings (300mA, 250V AC, -25°C ~ 120°C) remain identical.

Q: Can SS11VL-03550 be used as a direct replacement for SS11VL-R03820? A: SS11VL-03550 is a direct mechanical and electrical substitute with identical form factor and current/voltage ratings. The primary difference is reduced inductance (55 mH versus 82 mH). Substitution is valid when the circuit design specification permits this inductance reduction.

Q: Are there physical mounting differences between these three parts? A: All three parts use through-hole vertical mounting with 4 PC pin configuration. SS11VL-R03820 and SS11VL-03550 share identical dimensions (22.00mm L x 14.50mm W x 19.50mm H). SU10VFC-R03370 is more compact (18.00mm L x 15.50mm W x 15.00mm H), requiring verification of PCB layout compatibility.

Q: Do all substitute parts meet the same regulatory requirements? A: Yes. SS11VL-R03820, SS11VL-03550, and SU10VFC-R03370 are all ROHS3 compliant and REACH Unaffected, maintaining identical regulatory status for power line filtering applications.

Q: What is the primary electrical difference between the three parts? A: Inductance values differ: SS11VL-R03820 provides 82 mH, SS11VL-03550 provides 55 mH, and SU10VFC-R03370 provides 37 mH, all measured @ 1 kHz. DC resistance varies minimally (4.1Ohm or 4.2Ohm). Current and voltage ratings remain constant at 300mA and 250V AC.

Q: Which substitute offers the best space efficiency? A: SU10VFC-R03370 provides the most compact footprint at 18.00mm L x 15.50mm W x 15.00mm H, compared to the 22.00mm L x 14.50mm W x 19.50mm H dimensions of the SS series parts.
