Substitute Part Grouping Explanation

The Bourns 9250A-683-RC qualifies as a direct substitute based on the following critical parameters:

• Inductance value: 68 µH (identical)
• Inductance tolerance: ±10% (identical)
• Current rating: 170 mA (identical)
• DC resistance: 2.7 Ohm maximum (identical)
• Saturation current: 150 mA (identical)
• Shielding: Shielded (identical)
• Core material: Ferrite (identical)
• Mounting type: Through hole axial (identical)
• Physical dimensions: 0.162" Dia x 0.410" L (identical)
• Q factor: 50 @ 2.5 MHz (identical)
• Self resonant frequency: 21 MHz (identical)

The primary difference is the core construction type: the 9250-683-RC uses drum core wirewound construction, while the 9250A-683-RC uses molded construction. Both maintain identical electrical performance specifications and physical form factor, enabling direct substitution in circuit applications.
