Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IMS5SWDBH471K65 is determined by the following critical parameters:

• Inductance Value: 470 µH (exact match required)
• Current Rating: Minimum 180 mA
• DC Resistance: Maximum 9.5 Ohm
• Shielding: Shielded configuration
• Mounting Type: Through Hole
• Package Style: Axial

The substitute part 8250-471K-RC from Bourns Inc. meets all substitution criteria. This part maintains the same inductance specification and shielded axial through-hole configuration while offering improved current handling capability (192 mA) and lower DC resistance (6.45 Ohm maximum), making it functionally compatible for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The 8250-471K-RC qualifies as a direct substitute for the IMS5SWDBH471K65 based on matching inductance, shielding configuration, and mounting specifications. The substitute part provides enhanced electrical performance with higher current rating (192 mA vs. 180 mA) and reduced DC resistance (6.45 Ohm vs. 9.5 Ohm maximum), resulting in lower power dissipation in equivalent operating conditions.

The Bourns 8250-471K-RC carries ROHS3 compliance certification and operates across the industrial temperature range of -55°C to 105°C. The substitute part is manufactured using drum core wirewound construction, which differs from the molded construction of the original part but maintains functional equivalence for the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 8250-471K-RC replace the IMS5SWDBH471K65 in existing designs?

A: Yes. Both parts share identical inductance (470 µH), shielding configuration, and axial through-hole mounting. The substitute part meets or exceeds all critical electrical specifications of the original part.

Q: What is the difference between molded and drum core wirewound construction?

A: Molded inductors use a solid encapsulation process, while drum core wirewound inductors use a ferrite core with wire windings. Both construction methods achieve the specified inductance and shielding performance. The wirewound construction of the substitute part provides lower DC resistance.

Q: Are there any thermal considerations when substituting?

A: The substitute part operates across -55°C to 105°C. Verify that this temperature range aligns with your application requirements. The lower DC resistance of the substitute part (6.45 Ohm vs. 9.5 Ohm) results in reduced heat generation at equivalent current levels.

Q: What is the tolerance specification for the original part?

A: Tolerance for the IMS5SWDBH471K65 is not specified in the provided data. The substitute part carries ±10% inductance tolerance.

Q: Are both parts RoHS compliant?

A: RoHS compliance status for the IMS5SWDBH471K65 is not specified in the provided data. The 8250-471K-RC is ROHS3 compliant.
