Bourns 2218-V Equivalent & Substitute Parts

Part Overview

The Bourns 2218-V is a 330 µH shielded toroidal inductor rated for 3.3 A continuous current with a maximum DC resistance of 100 mOhm. This through-hole component features an iron powder core and operates across the temperature range of -55°C to 105°C. The 2218-V is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2218-V is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance value: 330 µH
• Inductance tolerance: ±15%
• Current rating: 3.3 A minimum
• DC resistance: 100 mOhm maximum
• Core material: Iron Powder
• Shielding configuration: Shielded
• Mounting type: Through Hole
• Package configuration: Radial, Vertical (Open)
• Physical dimensions: 0.950" Dia × 0.550" W
• Operating temperature range: -55°C to 105°C

The substitute part 2218-V-RC meets all these criteria and belongs to the same Bourns 2200 series family.

Parameter Comparison

Engineering Selection Recommendations

The 2218-V-RC is the direct substitute for the obsolete 2218-V. Both components are manufactured by Bourns Inc. and share identical electrical specifications and physical dimensions. The primary distinction is product status and regulatory compliance: the 2218-V-RC is an active product with ROHS3 compliance, whereas the 2218-V is obsolete and RoHS non-compliant.

For new designs or production continuity, the 2218-V-RC is the appropriate selection. The substitute maintains full electrical and mechanical compatibility with the original part, requiring no circuit modifications or PCB layout changes.

Frequently Asked Questions (FAQ)

Q: Can the 2218-V-RC be used as a direct replacement for the 2218-V?

A: Yes. The 2218-V-RC is electrically and mechanically identical to the 2218-V across all specified parameters, including inductance, current rating, DC resistance, core material, shielding, mounting type, package configuration, and physical dimensions.

Q: What is the difference between the 2218-V and 2218-V-RC?

A: The primary differences are product status and regulatory compliance. The 2218-V is obsolete and RoHS non-compliant, while the 2218-V-RC is an active product with ROHS3 compliance. Both parts are functionally equivalent.

Q: Are there any PCB layout or circuit design changes required when switching from 2218-V to 2218-V-RC?

A: No. The identical physical dimensions (0.950" Dia × 0.550" W) and through-hole radial vertical mounting configuration ensure direct PCB compatibility without layout modifications.

Q: What packaging options are available for the 2218-V-RC?

A: The 2218-V-RC is supplied in bulk packaging, whereas the original 2218-V was supplied with standard packaging.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 2218-V and 2218-V-RC operate across -55°C to 105°C, ensuring thermal compatibility in equivalent applications.
