Substitute Part Grouping Explanation

Substitution eligibility for the SWS-0.34-39 is determined by the following critical parameters:

  • Inductance Value: 39 µH (exact match required)
  • Tolerance: ±20% (must match or be tighter)
  • Current Rating: 340 mA (minimum requirement)
  • DC Resistance: 800mOhm (exact match required)
  • Mounting Type: Surface Mount (required for PCB compatibility)
  • Package Type: Nonstandard toroidal form factor
  • Compliance: ROHS3 and REACH status alignment

The PE-53806SNL qualifies as a direct substitute based on matching inductance, tolerance, current rating, and DC resistance specifications. The primary distinction is the shielding configuration (shielded versus unshielded) and minor dimensional variations, which do not affect electrical performance for equivalent circuit applications.

Engineering Selection Recommendations

Both the SWS-0.34-39 and PE-53806SNL are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

The SWS-0.34-39 is recommended for applications requiring unshielded toroidal inductors with a maximum seated height of 4.95mm. The PE-53806SNL is suitable for applications where shielded construction is beneficial and where the increased height of 6.86mm is accommodated within the PCB layout. Both components maintain identical electrical specifications for inductance, current rating, and DC resistance, ensuring functional equivalence in circuit applications.

Selection between these parts should be based on shielding requirements and available board space. The PE-53806SNL offers extended operating temperature capability to 130°C, providing additional thermal margin in high-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can PE-53806SNL be used as a direct replacement for SWS-0.34-39?

A: Yes, the PE-53806SNL is electrically equivalent for applications where shielding is acceptable or beneficial. The primary difference is the shielded construction of the PE-53806SNL versus the unshielded design of the SWS-0.34-39. Both components share identical inductance (39 µH), current rating (340 mA), and DC resistance (800mOhm) specifications.

Q: What is the impact of the height difference between these two parts?

A: The SWS-0.34-39 has a maximum seated height of 4.95mm, while the PE-53806SNL measures 6.86mm. This 1.91mm difference may affect PCB layout and component placement. Verify available vertical clearance in your design before substitution.

Q: Are there any compliance differences between these parts?

A: Both components are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution from a regulatory standpoint.

Q: Does shielding affect circuit performance?

A: Shielding reduces electromagnetic interference emission and susceptibility. The PE-53806SNL's shielded design may provide improved performance in noise-sensitive applications, while the unshielded SWS-0.34-39 is suitable for general-purpose filtering and energy storage applications.

Q: What is the packaging difference?

A: The SWS-0.34-39 is supplied in Tape & Reel (TR) packaging, while the PE-53806SNL is supplied in Bulk packaging. Confirm packaging compatibility with your procurement and assembly processes.
