Substitute Part Grouping Explanation

Substitution eligibility for the SC-05-800 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Manufacturer: KEMET
• Series: SC
• Filter Type: Power Line
• Number of Lines: 2
• Current Rating (Max): 4A
• Voltage Rating - DC: 250V
• Voltage Rating - AC: 250V
• Mounting Type: Through Hole
• Package / Case: Vertical, No Base, 4 PC Pin
• Operating Temperature Range: -40°C to 105°C

Allowable Variation Parameters:

• Inductance @ Frequency: Different inductance values and measurement frequencies are permitted based on application requirements
• DC Resistance (Max): Variation within acceptable limits for the power line filtering function

The SC-04-500 qualifies as a parametric equivalent because it maintains all mandatory matching criteria while offering different inductance (5 mH @ 10 kHz) and lower DC resistance (70 mOhm), providing alternative performance characteristics within the same product family and mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the SC-05-800 and SC-04-500 maintain active product status with full RoHS3 compliance and REACH unaffected designation, ensuring regulatory compliance for current and future applications. Selection between these parts is based on inductance and DC resistance requirements specific to the application circuit.

The SC-05-800 provides 8 mH inductance at 100 kHz with 85 mOhm DC resistance. The SC-04-500 provides 5 mH inductance at 10 kHz with 70 mOhm DC resistance. Both components share identical current ratings, voltage ratings, operating temperature ranges, and through-hole mounting configurations. The SC-04-500 exhibits a smaller physical footprint (29.00mm diameter versus 34.00mm diameter) and lower DC resistance, which may reduce power dissipation in applications where lower inductance values are acceptable.

Frequently Asked Questions (FAQ)

Q: Can SC-04-500 be used as a direct replacement for SC-05-800?

A: The SC-04-500 is a parametric equivalent within the KEMET SC series. Both parts share identical current ratings (4A), voltage ratings (250V DC/AC), operating temperature range (-40°C to 105°C), and through-hole mounting configuration. The primary difference is inductance value (5 mH @ 10 kHz versus 8 mH @ 100 kHz) and DC resistance (70 mOhm versus 85 mOhm). Substitution is valid only when the application circuit tolerates the lower inductance value and benefits from reduced DC resistance.

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

A: The SC-05-800 measures 1.339" diameter x 0.906" width (34.00mm x 23.00mm) with a maximum height of 1.339" (34.00mm). The SC-04-500 measures 1.142" diameter (29.00mm) with a maximum height of 1.142" (29.00mm). Both use identical vertical, no-base, 4-pin through-hole package configurations. The SC-04-500 occupies less board space.

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

A: Both SC-05-800 and SC-04-500 are RoHS3 compliant and REACH unaffected. Both maintain active product status. No compliance or certification differences exist between these parts.

Q: What is the significance of the different inductance measurement frequencies?

A: The SC-05-800 inductance is specified at 100 kHz, while the SC-04-500 is specified at 10 kHz. These measurement frequencies reflect the frequency-dependent behavior of the components. Application requirements determine which frequency specification is relevant for circuit design.

Q: How does DC resistance affect component selection?

A: The SC-04-500 exhibits lower DC resistance (70 mOhm) compared to the SC-05-800 (85 mOhm). Lower DC resistance reduces power dissipation and heat generation during operation. Both components support the same 4A maximum current rating. Selection depends on thermal management requirements and acceptable power loss in the application circuit.
