SWT-0.56-55 Equivalent & Substitute Parts

Part Overview

The SWT-0.56-55 is a 55 µH unshielded toroidal inductor manufactured by Amgis, LLC, rated for 560 mA continuous current with 500mOhm DC resistance. This through-hole component features an iron powder core and is designed for radial, horizontal mounting with open terminals. The part is currently obsolete, making identification of compatible substitutes essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SWT-0.56-55 is determined by strict equivalence across the following critical parameters:

• Inductance value: 55 µH (±20% tolerance band)
• Current rating: 560 mA minimum
• DC resistance: 500mOhm
• Core material: Iron Powder
• Shielding configuration: Unshielded
• Operating temperature range: -40°C ~ 125°C minimum
• Mounting type: Through Hole
• Test frequency: 10 kHz

The SH150T-0.56-55 meets all substitution criteria. While package geometry differs (corner terminals vs. open terminals), both parts maintain identical electrical specifications and thermal performance, permitting direct functional substitution in circuit applications where physical layout can accommodate the dimensional variance.

Parameter Comparison

Engineering Selection Recommendations

The SH150T-0.56-55 is the qualified substitute for the obsolete SWT-0.56-55. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The SH150T-0.56-55 carries active product status, ensuring long-term availability and supply chain continuity.

The primary design consideration is physical footprint. The SH150T-0.56-55 occupies a larger board space (11.00mm x 11.20mm vs. 8.60mm x 8.60mm) and features corner terminals rather than open terminals. PCB layout modification is required to accommodate the different terminal configuration and increased dimensions. Electrical performance is identical across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the SH150T-0.56-55 replace the SWT-0.56-55 in existing designs?

A: Yes, provided PCB layout can accommodate the larger footprint (11.00mm x 11.20mm) and corner terminal configuration. All electrical specifications—inductance, current rating, DC resistance, and operating temperature—are identical.

Q: What is the primary difference between these two parts?

A: Terminal configuration and physical dimensions. The SWT-0.56-55 uses open terminals in a smaller 8.60mm x 8.60mm package, while the SH150T-0.56-55 uses corner terminals in an 11.00mm x 11.20mm package. Electrical performance is equivalent.

Q: Why is the SWT-0.56-55 obsolete?

A: The part is listed as obsolete by the manufacturer. The SH150T-0.56-55 from the same manufacturer (Amgis, LLC) provides equivalent electrical functionality with active product status.

Q: Are there any compliance differences?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: What is the inductance tolerance for both parts?

A: Both the SWT-0.56-55 and SH150T-0.56-55 carry ±20% inductance tolerance, measured at 10 kHz test frequency.
