Substitute Part Grouping Explanation

Substitution of the Bourns 9250-155-RC is determined by strict equivalence across the following critical parameters:

• Inductance Value: 1.5 mH with ±10% tolerance
• Current Rating: 55 mA minimum continuous current capability
• DC Resistance: 26.5 Ohm maximum
• Saturation Current: 33 mA minimum
• Core Type: Ferrite shielded construction
• Mounting Configuration: Through-hole axial package
• Physical Envelope: 0.162" diameter × 0.410" length

The Bourns 9250A-155-RC qualifies as a direct substitute based on matching all electrical specifications and mechanical form factor. The primary distinction is the transition from drum core to molded construction and advancement from obsolete to active product status.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 9250A-155-RC is the direct equivalent for the obsolete 9250-155-RC. Both components maintain identical electrical performance across inductance, current rating, DC resistance, and frequency characteristics. The 9250A-155-RC offers the advantage of active product status with extended operating temperature range (-55°C to 125°C versus -55°C to 105°C), ensuring long-term availability and supply chain stability. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system support. The transition from drum core to molded construction in the 9250A series provides improved mechanical robustness without altering electrical specifications or physical envelope.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-155-RC be used as a direct replacement for the 9250-155-RC in existing designs?
