Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SC-20-D010 are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine substitution eligibility:

Core Electrical Parameters (Must Match):

• Number of Lines: 2
• Current Rating (Max): 20A
• DC Resistance (Max): 8mOhm
• Voltage Rating - DC: 250V
• Voltage Rating - AC: 250V
• Operating Temperature Range: -40°C ~ 105°C
• Mounting Type: Through Hole
• Package / Case: Horizontal, No Base, 4 PC Pin

Variable Parameter (Allows Substitution):

• Inductance @ Frequency: Different inductance values (10 µH, 1 mH) are acceptable substitutes when electrical performance requirements permit

The SC-20-100 and SC-20-104 are parametric equivalents within the SC-20 series. Both maintain identical electrical ratings and thermal specifications while offering higher inductance values (1 mH @ 100 kHz) and different physical dimensions to accommodate various PCB layout requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SC-20-D010, SC-20-100, and SC-20-104—are active products with full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current and future applications.

Selection Criteria Based on Provided Parameters:

The SC-20-D010 is the smallest footprint option with 10 µH inductance, suitable for space-constrained PCB layouts. The SC-20-100 and SC-20-104 provide higher inductance (1 mH) with larger physical dimensions. Selection between SC-20-100 and SC-20-104 depends on available PCB space, as SC-20-104 offers a more compact diameter (52.00mm vs 60.00mm) while maintaining equivalent electrical specifications.

All parts maintain identical current ratings, voltage ratings, DC resistance, and operating temperature ranges, ensuring functional interchangeability within the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can SC-20-100 or SC-20-104 be used as direct replacements for SC-20-D010?

A: SC-20-100 and SC-20-104 are parametric equivalents with identical electrical ratings (20A current, 8mOhm DCR, 250V DC/AC, -40°C to 105°C operating range). The primary difference is inductance value (1 mH vs 10 µH) and physical dimensions. Substitution is valid only if the application circuit design permits the higher inductance value.

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

A: SC-20-D010 has a diameter of 34.00mm and height of 23.00mm. SC-20-100 measures 60.00mm diameter by 30.00mm height. SC-20-104 measures 52.00mm diameter by 31.00mm height. Selection depends on available PCB space and layout constraints.

Q: Are all three parts RoHS3 compliant?

A: Yes. SC-20-D010, SC-20-100, and SC-20-104 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference between SC-20-100 and SC-20-104?

A: Both parts have identical electrical specifications (1 mH inductance, 20A current, 8mOhm DCR). SC-20-104 offers a more compact diameter (52.00mm vs 60.00mm) while maintaining the same electrical performance, making it suitable for space-limited applications.

Q: Can these parts be used interchangeably in all applications?

A: Electrical interchangeability is confirmed for current rating, voltage rating, DC resistance, and operating temperature. However, the inductance difference (10 µH vs 1 mH) and physical dimensions must be evaluated against specific circuit requirements and PCB layout constraints before substitution.
