Key Parameters

Substitute Part Grouping Explanation

The FIT68-2-B is identified as a direct substitute for the FIT68-2 based on identical electrical and mechanical specifications. Substitution eligibility is determined by the following critical parameters:

• Inductance Value: 71.1 µH (exact match required)
• Current Rating: 3.4 A (exact match required)
• DC Resistance: 86.1 mOhm Max (exact match required)
• Core Material: Iron Powder (exact match required)
• Shielding Configuration: Unshielded (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Radial, Vertical (Open) (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Regulatory Compliance: ROHS3 Compliant (exact match required)

Both parts are manufactured by Triad Magnetics within the FIT series and maintain identical physical dimensions and electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both FIT68-2 and FIT68-2-B are Active status products manufactured by Triad Magnetics with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on inventory availability and supply chain requirements rather than technical differentiation. The FIT68-2-B currently maintains higher inventory levels (792 Pcs) compared to FIT68-2 (680 Pcs), making it suitable for applications requiring extended lead time assurance. Both parts are suitable for direct substitution in through-hole PCB applications requiring 71.1 µH inductance at 3.4 A current rating within the -40°C to 85°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can FIT68-2-B be used as a direct replacement for FIT68-2?

A: Yes. FIT68-2-B is a direct substitute with identical electrical specifications (71.1 µH inductance, 3.4 A current rating, 86.1 mOhm DC resistance), core material (iron powder), shielding configuration (unshielded), mounting type (through hole), package type (radial, vertical open), physical dimensions, and operating temperature range (-40°C to 85°C).

Q: Are there any differences in regulatory compliance between these parts?

A: No. Both FIT68-2 and FIT68-2-B are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8504.50.4000.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is determined by exact matching of inductance value (71.1 µH), current rating (3.4 A), DC resistance (86.1 mOhm max), core material (iron powder), shielding type (unshielded), mounting configuration (through hole), package type (radial, vertical open), and operating temperature range (-40°C to 85°C).

Q: Are the physical dimensions identical between FIT68-2 and FIT68-2-B?

A: Yes. Both parts have identical dimensions of 0.875" L x 0.475" W (22.22mm x 12.07mm) with a maximum seated height of 0.950" (24.13mm), ensuring identical PCB footprint compatibility.

Q: What is the inductance test frequency for these components?

A: Both parts are tested at 10 kHz for inductance value verification.
