Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SWS-0.16-178 are qualified based on the following critical parameters that determine functional equivalence:

• Inductance value: 178 µH (exact match required)
• Tolerance: ±20% (matching specification)
• Current Rating: 160 mA (minimum threshold)
• DC Resistance: 2.8Ohm (exact match required)
• Toroidal type configuration
• Surface mount mounting type
• Nonstandard package classification
• RoHS3 compliance
• MSL Level 1 rating

The PE-53802SNL qualifies as a substitute based on matching all critical electrical parameters. Mechanical dimensions and shielding characteristics differ but remain within acceptable tolerances for component substitution in this category.

Parameter Comparison

Engineering Selection Recommendations

Both the SWS-0.16-178 and PE-53802SNL maintain Active product status and are RoHS3 compliant with MSL Level 1 ratings, ensuring long-term availability and regulatory compliance. The primary distinction between these parts is shielding configuration and physical height. The SWS-0.16-178 is unshielded with a maximum seated height of 0.195", while the PE-53802SNL is shielded with a maximum seated height of 0.270". Selection between these parts depends on circuit layout constraints and electromagnetic interference requirements specific to the application. Both parts share identical electrical specifications for inductance, current rating, and DC resistance, making them functionally equivalent for applications where shielding and height clearance are not limiting factors.

Frequently Asked Questions (FAQ)

Q: What makes PE-53802SNL a valid substitute for SWS-0.16-178?

A: The PE-53802SNL matches all critical electrical parameters: 178 µH inductance, ±20% tolerance, 160 mA current rating, and 2.8Ohm DC resistance. Both components are toroidal surface mount inductors with RoHS3 compliance and MSL Level 1 ratings.

Q: What are the key differences between these parts?

A: The SWS-0.16-178 is unshielded with a maximum height of 0.195", while the PE-53802SNL is shielded with a maximum height of 0.270". Dimensional differences are minimal (8.60mm vs 8.64mm in length and width). Operating temperature ranges differ slightly (-40°C to 125°C vs -40°C to 130°C).

Q: Does shielding affect substitution compatibility?

A: Shielding is a design feature that affects electromagnetic interference characteristics. The unshielded SWS-0.16-178 and shielded PE-53802SNL are electrically equivalent but may perform differently in noise-sensitive applications. Circuit design requirements determine whether shielding is necessary.

Q: Are there packaging differences?

A: The SWS-0.16-178 is supplied in Tape & Reel (TR) packaging, while the PE-53802SNL is supplied in Tube packaging. Both are nonstandard package classifications. Packaging choice depends on assembly process requirements and volume needs.

Q: Can I use PE-53802SNL in a space-constrained PCB layout?

A: The PE-53802SNL has a maximum seated height of 0.270" compared to 0.195" for the SWS-0.16-178. If vertical clearance is limited, the additional 0.075" height may create layout conflicts. Verify PCB clearance specifications before substitution.
