FIT106-5 Equivalent & Substitute Parts Reference

Part Overview

The FIT106-5 is a 93 µH unshielded toroidal inductor manufactured by Triad Magnetics, designed for through-hole mounting applications. This fixed inductor features an iron powder core with a current rating of 8.1 A and a maximum DC resistance of 39.1 mOhm. The component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FIT106-5 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part FIT106-5-B is classified as a direct equivalent because it maintains identical specifications in the following key areas:

• Inductance Value: 93 µH (exact match)
• Current Rating: 8.1 A (exact match)
• DC Resistance: 39.1 mOhm Max (exact match)
• Core Type: Iron Powder (exact match)
• Shielding Configuration: Unshielded (exact match)
• Mounting Configuration: Through Hole, Radial, Vertical (Open) (exact match)
• Physical Envelope: 1.300" L x 0.725" W, 1.400" Height (exact match)
• Operating Temperature: -40°C to 85°C (exact match)
• Regulatory Compliance: RoHS3 Compliant, REACH Unaffected (exact match)

No parameter deviation exists between the main part and substitute. Substitution is valid for direct replacement in all applications where FIT106-5 is specified.

Parameter Comparison

Engineering Selection Recommendations

Both FIT106-5 and FIT106-5-B are Active status components manufactured by Triad Magnetics and carry identical regulatory certifications (RoHS3 Compliant, REACH Unaffected). Selection between these parts is based on availability and procurement logistics rather than technical differentiation.

FIT106-5: 905 pieces in stock. Primary selection when immediate availability is required.

FIT106-5-B: 927 pieces in stock. Alternative selection with marginally higher inventory availability.

Both parts satisfy identical application requirements and carry equivalent compliance documentation. No technical preference exists between the two part numbers.

Frequently Asked Questions (FAQ)

Q: Can FIT106-5-B be used as a direct replacement for FIT106-5?

A: Yes. FIT106-5-B is a direct equivalent with identical inductance (93 µH), current rating (8.1 A), DC resistance (39.1 mOhm Max), core material (iron powder), shielding (unshielded), mounting type (through hole), physical dimensions, and operating temperature range (-40°C to 85°C). No circuit redesign or board layout modification is required.

Q: Are there any differences in physical footprint between FIT106-5 and FIT106-5-B?

A: No. Both parts share identical dimensions: 1.300" L x 0.725" W (33.02mm x 18.42mm) with a maximum seated height of 1.400" (35.56mm). PCB layout and mechanical clearance requirements are identical.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both FIT106-5 and FIT106-5-B are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8504.50.4000. Regulatory documentation is equivalent.

Q: What is the basis for substitution between these two part numbers?

A: Substitution is based on complete electrical and mechanical equivalence. All parameters including inductance value, current rating, DC resistance, core material, shielding configuration, mounting type, package dimensions, and operating temperature range are identical. Both parts are manufactured by Triad Magnetics within the FIT series.

Q: Can these parts be used in high-frequency applications?

A: The inductance test frequency is specified at 10 kHz. No additional frequency response data is provided in the component specifications. Application suitability at frequencies beyond the test specification requires reference to detailed manufacturer datasheets.

Q: Are there any lead time or availability advantages to selecting one part over the other?

A: FIT106-5-B currently has 927 pieces in stock compared to 905 pieces for FIT106-5. Both are classified as Active status with equivalent availability. Selection should be based on procurement lead time requirements and supplier inventory status at the time of ordering.
