Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SWS-0.46-78 is determined by the following critical parameters:

• Inductance value: 78 µH (exact match required)
• Tolerance: ±20% (exact match required)
• Current rating: 460 mA (exact match required)
• DC resistance: 800mOhm (exact match required)
• Mounting type: Surface Mount (exact match required)
• RoHS compliance: ROHS3 Compliant (required for regulatory alignment)

Two substitute parts meet these electrical and mechanical criteria: SH150S-0.46-78 from Amgis, LLC and PE-53812SNL from Pulse Electronics. Both maintain identical inductance, tolerance, current rating, and DC resistance specifications. Physical dimensions vary slightly between parts, and shielding characteristics differ, requiring evaluation based on circuit layout constraints.

Parameter Comparison

Engineering Selection Recommendations

SH150S-0.46-78 is the primary substitute for the obsolete SWS-0.46-78. Both parts are manufactured by Amgis, LLC and share identical electrical specifications. The SH150S-0.46-78 is currently active in production with higher inventory availability (1010 pcs). Physical dimensions increase by approximately 1.2mm in length and width, with seated height increasing by 0.9mm. This part maintains unshielded construction matching the original design. Moisture sensitivity level increases from MSL 1 to MSL 2, requiring one-year shelf-life management.

PE-53812SNL from Pulse Electronics provides an alternative with identical electrical performance and extended operating temperature range to 130°C. This part introduces shielded construction, which may alter electromagnetic coupling characteristics in the circuit. Physical dimensions are comparable to SH150S-0.46-78 with increased seated height of 9.14mm. Moisture sensitivity level remains at MSL 1 (unlimited). Selection between these substitutes depends on circuit layout constraints, electromagnetic interference requirements, and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can SH150S-0.46-78 directly replace SWS-0.46-78 in existing designs?

A: Yes. Both parts maintain identical inductance (78 µH), tolerance (±20%), current rating (460 mA), and DC resistance (800mOhm). Physical dimensions increase slightly, requiring verification of available PCB space. The unshielded construction remains consistent with the original design.

Q: What is the impact of shielding differences between SWS-0.46-78 and PE-53812SNL?

A: SWS-0.46-78 is unshielded while PE-53812SNL is shielded. Shielding reduces electromagnetic radiation and susceptibility to external fields. Circuit layout and electromagnetic compatibility requirements determine whether shielded construction is necessary or beneficial.

Q: Are there packaging differences between substitute parts?

A: SWS-0.46-78 uses nonstandard packaging. SH150S-0.46-78 is supplied in Tape & Reel (TR) format. PE-53812SNL is supplied in Bulk format. Packaging selection depends on production volume and assembly requirements.

Q: What is the significance of MSL rating differences?

A: SWS-0.46-78 and PE-53812SNL carry MSL 1 (unlimited shelf life). SH150S-0.46-78 carries MSL 2, requiring storage within one year of manufacture. MSL 2 components require controlled humidity storage and handling procedures during assembly.

Q: Do all substitute parts meet current regulatory requirements?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and use.
