SWC-4.3-10 Equivalent & Substitute Parts

Part Overview

The SWC-4.3-10 is a 10.2 µH unshielded toroidal inductor manufactured by Amgis, LLC, rated for 4.3 A continuous current with 26mOhm DC resistance. This component is designed for through-hole mounting applications requiring fixed inductance in the 10 µH range with iron powder core construction. The part maintains Active product status with full RoHS3 compliance and operates across the -40°C to 130°C temperature range. Substitute parts are identified when electrical specifications, mechanical compatibility, and regulatory compliance align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

The P0845NL from Pulse Electronics qualifies as a direct substitute based on the following critical parameters:

Electrical specifications match exactly: 10.2 µH inductance, 4.3 A current rating, 26mOhm DC resistance, and ±20% tolerance. Both components operate within the identical temperature range (-40°C to 130°C) and share the same through-hole mounting configuration with radial, vertical (open) package orientation. Mechanical compatibility is maintained despite dimensional differences, as both components fit the same PCB footprint classification. Both parts carry ROHS3 compliance and REACH Unaffected status, meeting identical regulatory requirements. The primary distinction is shielding: the SWC-4.3-10 is unshielded while the P0845NL is shielded, representing a design enhancement rather than a limitation for substitution purposes.

Parameter Comparison

Engineering Selection Recommendations

Both the SWC-4.3-10 and P0845NL maintain Active product status with equivalent regulatory compliance. The P0845NL offers shielded construction, which provides electromagnetic interference mitigation compared to the unshielded SWC-4.3-10. Selection between these parts depends on application-specific EMI requirements rather than electrical performance, as all critical specifications are identical. The P0845NL is available in higher inventory quantities (4426 pcs vs. 665 pcs), which may influence procurement decisions for volume applications. Both components satisfy identical compliance certifications and temperature operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the P0845NL replace the SWC-4.3-10 in existing designs?

A: Yes. Both inductors share identical electrical specifications (10.2 µH, 4.3 A, 26mOhm DCR) and operate within the same temperature range. The through-hole radial vertical mounting configuration is identical, ensuring PCB compatibility.

Q: What is the difference between shielded and unshielded versions?

A: The P0845NL includes electromagnetic shielding, which reduces radiated and conducted EMI. The SWC-4.3-10 is unshielded. This distinction affects EMI performance but not inductance, current rating, or DC resistance specifications.

Q: Are there dimensional compatibility concerns?

A: Both components use the same package classification (Radial, Vertical Open). The P0845NL is slightly smaller (14.74mm x 8.89mm vs. 16.50mm x 11.40mm), which presents no compatibility issues for standard through-hole PCB layouts.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the SWC-4.3-10 and P0845NL are ROHS3 compliant and REACH Unaffected, meeting identical environmental and safety standards.

Q: Which part should be selected for new designs?

A: Selection is based on EMI requirements. If electromagnetic shielding is beneficial, the P0845NL is the preferred choice. If shielding is unnecessary, either part satisfies the electrical requirements identically.
