Bourns 2218-H Equivalent & Substitute Parts

Part Overview

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

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 2218-H is determined by strict equivalence across the following parameters:

• Inductance value: 330 µH
• Inductance tolerance: ±15%
• Current rating: 3.3 A minimum
• DC resistance: 100mOhm maximum
• Core material: Iron powder
• Shielding configuration: Shielded
• Mounting technology: Through hole
• Package geometry: Radial, horizontal orientation
• Operating temperature range: -55°C to 105°C minimum

The 2218-H-RC qualifies as a direct substitute based on identical electrical specifications and mechanical dimensions within the Bourns 2200 series.

Parameter Comparison

Engineering Selection Recommendations

The 2218-H-RC is the direct equivalent for the obsolete 2218-H. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin and form-factor compatibility. The primary distinction is product status and regulatory compliance: the 2218-H-RC is currently active in production and meets ROHS3 compliance requirements, whereas the 2218-H is obsolete and RoHS non-compliant. For new designs or production continuity, the 2218-H-RC is the appropriate selection. Both components carry identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the 2218-H-RC replace the 2218-H in existing designs?

A: Yes. The 2218-H-RC is electrically and mechanically identical to the 2218-H. All electrical parameters, physical dimensions, and mounting characteristics are equivalent. Direct substitution is supported.

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

A: The primary differences are product status and packaging. The 2218-H is obsolete; the 2218-H-RC is active. The 2218-H-RC is supplied in bulk packaging and meets ROHS3 compliance, while the 2218-H is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any compliance considerations when switching from 2218-H to 2218-H-RC?

A: Yes. The 2218-H-RC meets ROHS3 compliance requirements, whereas the 2218-H does not. If your application or supply chain requires RoHS compliance, the 2218-H-RC is the appropriate choice.

Q: Will the 2218-H-RC fit the same PCB footprint as the 2218-H?

A: Yes. Both components are radial, horizontal-mount through-hole inductors with identical physical dimensions: 0.950" diameter and 0.550" height. PCB layout compatibility is maintained.

Q: What is the inductance tolerance for both parts?

A: Both the 2218-H and 2218-H-RC carry an inductance tolerance of ±15%, measured at 1 kHz.
