Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SWS-0.56-55 are identified based on the following critical electrical and mechanical parameters:

Primary Matching Criteria:

• Inductance value: 55 µH
• Inductance tolerance: ±20%
• Current rating: 560 mA
• DC resistance: 500mOhm
• Toroidal type with surface mount configuration
• ROHS3 compliance

Substitute Classification:

Direct Substitute (SH150S-0.56-55): Matches all electrical specifications and core material (iron powder). Differs in product status (active vs. obsolete) and packaging format (Tape & Reel vs. standard). Physical dimensions vary slightly (11.20mm x 11.00mm vs. 10.00mm x 10.00mm), with proportionally increased height (7.65mm vs. 6.75mm).

Similar Substitute (PE-53813SNL): Matches all electrical specifications and current rating. Differs in shielding configuration (shielded vs. unshielded), core material specification (not provided), and operating temperature upper limit (130°C vs. 125°C). Physical dimensions are comparable (11.18mm x 11.05mm) with increased height (9.14mm).

Parameter Comparison

Engineering Selection Recommendations

SH150S-0.56-55 Selection Criteria: This part is recommended as the primary substitute for the obsolete SWS-0.56-55. Both parts are manufactured by Amgis, LLC and share identical electrical specifications, inductance tolerance, current rating, and DC resistance. The SH150S-0.56-55 maintains active product status with confirmed inventory availability. ROHS3 compliance is maintained. The primary design consideration is the increased footprint (11.20mm x 11.00mm vs. 10.00mm x 10.00mm) and height (7.65mm vs. 6.75mm), which must be evaluated against available PCB space and assembly clearances.

PE-53813SNL Selection Criteria: This Pulse Electronics part provides an alternative substitute when the SH150S-0.56-55 is unavailable or when shielded configuration is required for EMI mitigation. Electrical specifications match the original part. The shielded design introduces electromagnetic isolation not present in the original unshielded design. Operating temperature extends to 130°C, providing additional thermal margin. Physical dimensions are comparable to the SH150S-0.56-55 (11.18mm x 11.05mm), but height is significantly increased (9.14mm), requiring PCB layout verification. Core material is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can SH150S-0.56-55 be used as a direct replacement for SWS-0.56-55? A: Yes. Both parts share identical inductance (55 µH), tolerance (±20%), current rating (560 mA), and DC resistance (500mOhm). The primary design consideration is the increased physical dimensions. Verify PCB layout accommodates the larger footprint (11.20mm x 11.00mm) and height (7.65mm).

Q: What is the key difference between SH150S-0.56-55 and PE-53813SNL? A: The primary difference is shielding configuration. SH150S-0.56-55 is unshielded (matching the original SWS-0.56-55), while PE-53813SNL is shielded. Both maintain identical electrical specifications. PE-53813SNL has increased height (9.14mm vs. 7.65mm), requiring additional PCB clearance verification.

Q: Why is the SWS-0.56-55 classified as obsolete? A: The SWS-0.56-55 is listed as obsolete by the manufacturer. The active substitute SH150S-0.56-55 from the same manufacturer (Amgis, LLC) provides equivalent electrical performance and is recommended for new designs and ongoing procurement.

Q: Are all substitute parts ROHS3 compliant? A: Yes. Both SH150S-0.56-55 and PE-53813SNL maintain ROHS3 compliance, matching the original SWS-0.56-55 specification.

Q: What packaging formats are available for these parts? A: SWS-0.56-55 is supplied in standard packaging. SH150S-0.56-55 is available in Tape & Reel (TR) format. PE-53813SNL is supplied in Bulk packaging. Packaging selection depends on procurement volume and assembly process requirements.

Q: Can PE-53813SNL be used in applications requiring unshielded inductors? A: PE-53813SNL is a shielded inductor. While electrical specifications match, the shielded design alters electromagnetic field distribution. Use only when shielding does not conflict with circuit design requirements or when EMI mitigation is beneficial.
