FIT80-6 Equivalent & Substitute Parts Reference

Part Overview

The FIT80-6 is a 38.07 µH unshielded toroidal inductor manufactured by Triad Magnetics, designed for through-hole mounting applications requiring moderate current handling. This iron powder core component operates across the -40°C to 85°C temperature range and is specified for 10 kHz inductance testing. The part maintains Active product status with ROHS3 compliance and REACH unaffected classification. Substitute parts are identified to support procurement continuity, inventory management, and design flexibility when the primary part number becomes unavailable or when equivalent electrical and mechanical specifications are required.

Substitute Part Grouping Explanation

Substitute parts for the FIT80-6 are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are defined by the following parameters:

Electrical Equivalence Parameters:

• Inductance value: 38.07 µH (exact match required)
• Current rating: 9.7 A (exact match required)
• DC resistance: 17 mOhm maximum (exact match required)
• Core material: Iron Powder (exact match required)
• Shielding configuration: Unshielded (exact match required)
• Operating temperature range: -40°C to 85°C (exact match required)

Mechanical Equivalence Parameters:

• Mounting type: Through Hole (exact match required)
• Package / Case: Radial, Vertical (Open) (exact match required)
• Physical dimensions: 24.76 mm L × 15.88 mm W (exact match required)
• Height seated maximum: 27.94 mm (exact match required)

Compliance & Status Parameters:

• Product status: Active (required for current procurement)
• RoHS compliance: ROHS3 Compliant (required for regulatory alignment)
• REACH status: REACH Unaffected (required for regulatory alignment)

The FIT80-6-B is classified as a direct substitute because it meets all electrical, mechanical, and compliance criteria specified above.

Parameter Comparison

Engineering Selection Recommendations

Both FIT80-6 and FIT80-6-B are Active products with identical electrical specifications, mechanical dimensions, and regulatory compliance certifications. Selection between these parts is determined by inventory availability and procurement requirements rather than technical performance differences.

FIT80-6 is the primary part number with 1053 units in current stock inventory.

FIT80-6-B is the direct substitute with 975 units in current stock inventory and serves as an alternative when primary stock is depleted or when procurement lead times require secondary sourcing.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications subject to environmental and hazardous substance restrictions. The identical electrical and mechanical specifications ensure direct interchangeability in circuit designs and PCB layouts without modification to component footprints, thermal management, or electrical performance calculations.

Frequently Asked Questions (FAQ)

Q: Can FIT80-6-B be used as a direct replacement for FIT80-6 in existing designs?

A: Yes. FIT80-6-B is electrically and mechanically identical to FIT80-6. All electrical parameters (inductance, current rating, DC resistance), core material, shielding configuration, mounting type, package dimensions, and operating temperature range are equivalent. No circuit redesign or PCB layout modification is required.

Q: Are there any differences in compliance or regulatory status between FIT80-6 and FIT80-6-B?

A: No. Both parts carry identical ROHS3 compliance and REACH unaffected status. Both maintain Active product status with Triad Magnetics as the manufacturer.

Q: What determines whether a part qualifies as a substitute for FIT80-6?

A: Substitution is based on exact equivalence across all specified electrical parameters (38.07 µH inductance, 9.7 A current rating, 17 mOhm maximum DC resistance), core material (iron powder), shielding type (unshielded), mechanical dimensions (24.76 × 15.88 × 27.94 mm), mounting configuration (through-hole radial vertical), and operating temperature range (-40°C to 85°C).

Q: Can inductors with different inductance values or current ratings substitute for FIT80-6?

A: No. Inductance value and current rating are critical electrical parameters. Substitutes must match the specified 38.07 µH inductance and 9.7 A current rating exactly. Deviations alter circuit performance and are not permitted under substitution criteria.

Q: What is the significance of the 10 kHz inductance test frequency?

A: The 10 kHz test frequency is the standard measurement condition at which the 38.07 µH inductance value is specified and verified. Substitute parts must be tested at the same frequency to ensure measurement consistency and electrical equivalence.

Q: Are there inventory considerations when selecting between FIT80-6 and FIT80-6-B?

A: Yes. FIT80-6 has 1053 units in stock, while FIT80-6-B has 975 units. For high-volume procurement or long-term supply assurance, inventory levels should be evaluated. Both parts are Active products with ongoing availability.

Q: Do the physical dimensions affect PCB layout compatibility?

A: No. Both FIT80-6 and FIT80-6-B have identical dimensions (24.76 mm L × 15.88 mm W, 27.94 mm height seated maximum) and identical radial vertical through-hole mounting configuration. PCB footprints and component placement are fully compatible without modification.
