SC10F-220 Equivalent & Substitute Parts

Part Overview

The SC10F-220 is a 22 µH unshielded wirewound inductor rated for 3 A continuous current with a maximum DC resistance of 75mOhm, manufactured by Signal Transformer. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. Substitute parts must maintain the same inductance value, tolerance, and operating temperature range while accommodating variations in current rating and DC resistance within acceptable design margins.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

• Inductance Value: Must be 22 µH ±20% tolerance
• Mounting Type: Must be Surface Mount
• Shielding Configuration: Must be Unshielded
• Test Frequency: Must be 100 kHz
• Compliance: Must maintain ROHS3 and REACH compliance status
• Current Handling: Substitute current rating must be ≥2.8 A minimum to support typical circuit requirements
• DC Resistance: Acceptable range 61.7mOhm to 85mOhm, with lower values preferred for reduced power dissipation
• Operating Temperature: Minimum range -40°C to 85°C acceptable; 125°C upper limit preferred

The following parts meet these substitution criteria:

1. IDC5020ER220M (Vishay Dale) – Active status, 2.7 A rating, 85mOhm DCR
2. UP2B-220-R (Eaton - Electronics Division) – Active status, 2.8 A rating, 61.7mOhm DCR

Parameter Comparison

Engineering Selection Recommendations

IDC5020ER220M (Vishay Dale) is suitable for applications where the operating temperature range of -40°C to 125°C is required and where the slightly higher DC resistance of 85mOhm is acceptable. This part maintains full temperature range compatibility with the original SC10F-220 and is currently in active production status with established supply chain availability.

UP2B-220-R (Eaton - Electronics Division) offers superior DC resistance performance at 61.7mOhm, resulting in lower power dissipation compared to both the original part and the Vishay alternative. This part is actively manufactured and widely available. The operating temperature upper limit of 85°C is suitable for applications not requiring the full 125°C capability. The UNI-PAC™ series construction provides established reliability in high-volume applications.

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component. Selection between these alternatives should be based on specific application requirements regarding maximum operating temperature and acceptable DC resistance levels.

Frequently Asked Questions (FAQ)

Q: Can IDC5020ER220M or UP2B-220-R be used as direct replacements for SC10F-220?

A: Both parts are functionally equivalent substitutes based on inductance value, tolerance, mounting type, and shielding configuration. However, circuit design must accommodate the reduced current ratings (2.7 A and 2.8 A respectively versus 3 A) and variations in DC resistance. For applications operating above 85°C, only IDC5020ER220M maintains the full temperature range of the original part.

Q: What is the impact of DC resistance differences between these parts?

A: The original SC10F-220 specifies 75mOhm maximum DCR. IDC5020ER220M has 85mOhm maximum, while UP2B-220-R has 61.7mOhm maximum. Higher DC resistance increases power dissipation (P = I²R). For a 2.8 A circuit, UP2B-220-R dissipates approximately 0.48 W compared to 0.59 W for IDC5020ER220M. Design thermal analysis should account for these differences.

Q: Are there physical size differences between these parts?

A: Yes. SC10F-220 dimensions are 0.453" L x 0.382" W x 0.197" H. IDC5020ER220M is 0.510" L x 0.370" W x 0.205" H. UP2B-220-R is 0.550" L x 0.410" W x 0.236" H. PCB layout must accommodate these dimensional variations.

Q: Which substitute part should be selected for high-temperature applications?

A: IDC5020ER220M supports the full -40°C to 125°C operating range matching the original SC10F-220. UP2B-220-R is limited to -40°C to 85°C and is not suitable for applications requiring operation above 85°C.

Q: Are both substitute parts available in Tape & Reel packaging?

A: Yes. Both IDC5020ER220M and UP2B-220-R are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
