Bourns 2104-V 18µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2104-V is an 18µH unshielded toroidal inductor rated for 7.4A continuous current with a maximum DC resistance of 13mOhm. This through-hole component operates across the temperature range of -55°C to 105°C and is part of the 2100 series inductor family. The 2104-V carries an obsolete product status, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The 2104-V-RC qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Inductance value and tolerance match (18µH ±15%)
• Current rating equivalence (7.4A minimum)
• DC resistance specification compliance (13mOhm maximum)
• Identical shielding configuration (unshielded)
• Matching mounting and package type (through-hole, radial vertical open)
• Physical dimensions compatibility (0.860" Dia × 0.450" W)
• Operating temperature range coverage (-55°C to 105°C)

The 2104-V-RC maintains all electrical performance characteristics while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 2104-V-RC is the appropriate selection for applications currently specified with the 2104-V. The substitute part maintains complete electrical and mechanical compatibility while offering active product status and RoHS3 compliance. The transition from RoHS non-compliant to RoHS3 compliant status aligns with current regulatory requirements for electronic component procurement. Both parts share identical inductance, current rating, DC resistance, and physical form factor specifications, ensuring direct functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the 2104-V-RC be used as a direct replacement for the 2104-V?

A: Yes. The 2104-V-RC provides identical electrical performance (18µH inductance, 7.4A current rating, 13mOhm DC resistance) and mechanical compatibility (through-hole mounting, radial vertical package, 0.860" Dia × 0.450" W dimensions). The substitute part operates across the same temperature range (-55°C to 105°C).

Q: What is the primary difference between these two parts?

A: The 2104-V-RC is an active product with RoHS3 compliance, while the 2104-V is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between the 2104-V and 2104-V-RC?

A: The 2104-V ships in standard packaging, while the 2104-V-RC is supplied in bulk packaging. Both maintain the same component specifications and physical dimensions.

Q: Does the inductance tolerance affect substitution?

A: Both parts share ±15% inductance tolerance at 1 kHz test frequency. Tolerance specifications are identical and do not impact substitution eligibility.

Q: What compliance certifications apply to the 2104-V-RC?

A: The 2104-V-RC is RoHS3 compliant and REACH unaffected. It carries EAR99 export classification and HTSUS code 8504.50.4000.
