Bourns 2203-V Equivalent & Substitute Parts

Part Overview

The Bourns 2203-V is a 15 µH shielded toroidal inductor rated for 11.3 A continuous current with 8mOhm maximum DC resistance. This through-hole component features an iron powder core and operates across the temperature range of -55°C to 105°C. The 2203-V carries an obsolete product status, making identification of equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 2203-V is determined by strict equivalence across the following critical parameters:

• Inductance Value: 15 µH with ±15% tolerance
• Current Rating: 11.3 A minimum
• DC Resistance: 8mOhm maximum
• Core Type: Iron powder construction
• Shielding Configuration: Shielded design
• Mounting Interface: Through-hole radial vertical orientation
• Physical Envelope: 0.950" diameter x 0.550" width
• Temperature Operating Range: -55°C to 105°C

The Bourns 2203-V-RC meets all these parameters identically, establishing it as a direct functional equivalent. Both components share the same base product number (2203) and series designation (2200), confirming design compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 2203-V-RC is the direct substitute for the obsolete 2203-V. Both components are electrically and mechanically identical across all functional parameters. The primary distinction is product status and regulatory compliance:

The 2203-V-RC carries active product status, ensuring continued availability and manufacturing support. The substitute achieves ROHS3 compliance, whereas the original 2203-V is RoHS non-compliant. For new designs or procurement requiring regulatory alignment with current environmental standards, the 2203-V-RC is the appropriate selection. Both components maintain identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the 2203-V-RC be used as a direct replacement for the 2203-V in existing designs?

A: Yes. The 2203-V-RC is electrically and mechanically equivalent. All critical parameters—inductance, current rating, DC resistance, core material, shielding, mounting type, physical dimensions, and operating temperature range—are identical. PCB layout and circuit integration require no modification.

Q: What is the difference between the 2203-V and 2203-V-RC?

A: The components are functionally identical. The 2203-V-RC is the active production variant with ROHS3 compliance, while the 2203-V is obsolete and RoHS non-compliant. Packaging differs (bulk for 2203-V-RC versus standard for 2203-V), but electrical and mechanical specifications are unchanged.

Q: Are there any compliance considerations when switching from 2203-V to 2203-V-RC?

A: The 2203-V-RC achieves ROHS3 compliance, making it suitable for applications subject to RoHS directives. Both components maintain identical REACH and ECCN classifications. Regulatory requirements specific to your application should be evaluated independently.

Q: Does the through-hole radial vertical mounting orientation remain the same?

A: Yes. Both the 2203-V and 2203-V-RC use identical through-hole radial vertical (open) mounting. Physical dimensions are 0.950" diameter x 0.550" width. No PCB footprint or assembly process changes are required.

Q: What is the inductance tolerance for these components?

A: Both the 2203-V and 2203-V-RC carry ±15% inductance tolerance, measured at 1 kHz. This tolerance applies to the 15 µH nominal value across the full operating temperature range of -55°C to 105°C.
