FIT80-5 Equivalent & Substitute Parts Reference

Part Overview

The FIT80-5 is a 47.7 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 maximum DC resistance of 22.5 mOhm. The component operates across the temperature range of -40°C to 85°C and is classified as Active product status. Substitute parts are identified to provide alternative sourcing options when primary inventory availability is constrained or when procurement from multiple suppliers is required for supply chain resilience.

Parameter Comparison

Engineering Selection Recommendations

Both the FIT80-5 and FIT80-5-B are Active status products manufactured by Triad Magnetics within the FIT series. Both components maintain full compliance with ROHS3 requirements and REACH regulations. The electrical specifications, mechanical dimensions, and thermal operating range are identical across both part numbers.

Selection between FIT80-5 and FIT80-5-B should be based on inventory availability and procurement lead times. The FIT80-5-B currently maintains higher inventory levels (1139 pieces) compared to FIT80-5 (767 pieces), making it suitable for applications requiring immediate availability or larger volume requirements. Both parts are functionally interchangeable in circuit applications requiring 47.7 µH inductance at 8.1 A current rating with through-hole radial mounting configuration.

Frequently Asked Questions (FAQ)

Q: Are FIT80-5 and FIT80-5-B electrically identical?

A: Yes. Both components feature identical inductance (47.7 µH), current rating (8.1 A), DC resistance (22.5 mOhm maximum), core material (iron powder), and operating temperature range (-40°C to 85°C). They are tested at the same frequency (10 kHz) and share identical electrical characteristics.

Q: Can FIT80-5-B be used as a direct replacement for FIT80-5 in existing designs?

A: Yes. The FIT80-5-B is a direct substitute. Both components share identical mechanical dimensions (24.76 mm × 15.88 mm × 27.94 mm maximum height), mounting type (through-hole), and package configuration (radial, vertical open). PCB layout and mechanical assembly require no modification.

Q: What are the key parameters that define substitutability for this inductor?

A: Substitutability is determined by: inductance value (47.7 µH), current rating (8.1 A), DC resistance (22.5 mOhm maximum), core material (iron powder), shielding type (unshielded), mounting configuration (through-hole radial vertical), physical dimensions, and operating temperature range (-40°C to 85°C). All parameters must match exactly for direct substitution.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both FIT80-5 and FIT80-5-B are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the difference between FIT80-5 and FIT80-5-B?

A: The part numbers differ, but all electrical, mechanical, and compliance specifications are identical. The designation difference may reflect manufacturing batch, packaging variation, or supplier differentiation, but no functional or performance distinction exists between the two parts.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and procurement lead times. The FIT80-5-B currently maintains higher stock levels, making it preferable for designs requiring rapid prototyping or production ramp-up.
