SWC-5.0-33 Equivalent & Substitute Parts

Part Overview

The SWC-5.0-33 is a 33 µH unshielded toroidal inductor manufactured by Amgis, LLC, rated for 5 A continuous current with 47 mOhm DC resistance. This component is designed for through-hole mounting applications requiring fixed inductance in the 33 µH range with moderate current handling capability. The part is Active status and ROHS3 compliant, making it suitable for modern electronic assemblies. Substitute parts may be required due to inventory constraints, packaging preferences, or application-specific shielding requirements.

Key Parameters

Substitute Part Grouping Explanation

The P0849NL from Pulse Electronics qualifies as a direct substitute based on the following critical parameters:

• Inductance Value: Both parts specify 33 µH
• Current Rating: Both rated for 5 A
• DC Resistance: Both measure 47 mOhm
• Tolerance: Both maintain ±20% tolerance
• Type: Both are toroidal inductors
• Mounting Type: Both are through-hole mounted
• Package / Case: Both use Radial, Vertical (Open) configuration
• Operating Temperature: Both operate across -40°C ~ 130°C
• Compliance: Both are ROHS3 compliant and REACH unaffected

The primary difference between these parts is shielding: the SWC-5.0-33 is unshielded, while the P0849NL is shielded. Physical dimensions vary slightly, with the P0849NL having a greater seated height (34.29 mm vs. 26.90 mm).

Parameter Comparison

Engineering Selection Recommendations

Both the SWC-5.0-33 and P0849NL meet identical electrical specifications for inductance, current rating, and DC resistance. Selection between these parts depends on application-specific requirements:

SWC-5.0-33 (Amgis, LLC) is appropriate when unshielded operation is acceptable and compact vertical height is required (26.90 mm seated height). This part is Active status with ROHS3 compliance.

P0849NL (Pulse Electronics) is appropriate when electromagnetic shielding is necessary to reduce radiated emissions or susceptibility to external magnetic fields. This part is also Active status with ROHS3 compliance. The increased seated height (34.29 mm) must be verified against PCB layout constraints. Packaging in trays may be preferred for automated assembly processes.

Both parts maintain compliance with ROHS3 and REACH regulations, ensuring suitability for regulated markets.

Frequently Asked Questions (FAQ)

Q: Can P0849NL replace SWC-5.0-33 in all applications?

A: Electrical substitution is valid based on matching inductance (33 µH), current rating (5 A), and DC resistance (47 mOhm). However, the shielded design of P0849NL introduces electromagnetic isolation not present in the unshielded SWC-5.0-33. PCB layout must accommodate the increased seated height of 34.29 mm versus 26.90 mm.

Q: What is the significance of shielding in these inductors?

A: Shielding reduces electromagnetic radiation and external field susceptibility. The unshielded SWC-5.0-33 is suitable for applications where EMI is not a concern. The shielded P0849NL is specified for noise-sensitive circuits or environments with high electromagnetic activity.

Q: Are there packaging considerations for automated assembly?

A: The SWC-5.0-33 is supplied in Bulk packaging, while P0849NL is supplied in Tray packaging. Tray packaging is typically preferred for pick-and-place assembly operations.

Q: Do both parts meet regulatory requirements?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations for electronic components.

Q: What tolerance should be expected from these inductors?

A: Both parts maintain ±20% inductance tolerance at the 10 kHz test frequency specified for the SWC-5.0-33.
