Substitute Part Grouping Explanation

The substitute part 5900-681-RC from Bourns Inc. qualifies as an equivalent based on the following alignment of critical parameters:

• Inductance value: 680 µH (identical)
• Core type and material: Drum core, ferrite (identical)
• Mounting configuration: Through hole, axial package (identical)
• Shielding: Unshielded (identical)
• Test frequency: 1 kHz (identical)
• RoHS compliance: ROHS3 compliant (identical)
• Current rating: 900 mA (within acceptable range of main part's 1 A rating)
• DC resistance: 515 mOhm Max (lower than main part's 570 mOhm, acceptable for substitution)
• Operating temperature: -55°C ~ 105°C (overlaps with main part's range)

Parameter Comparison

Engineering Selection Recommendations

Both the IHD3EB681L and 5900-681-RC are active production components with ROHS3 compliance and REACH unaffected status. The 5900-681-RC offers improved DC resistance characteristics (515 mOhm versus 570 mOhm) and tighter inductance tolerance (±10% versus ±15%). Selection between these parts depends on application current requirements: the IHD3EB681L supports 1 A continuous current, while the 5900-681-RC is rated for 900 mA. Both components maintain identical inductance values, core construction, and axial through-hole mounting configuration, ensuring mechanical and electrical compatibility within their respective current ratings.

Frequently Asked Questions (FAQ)

Q: Can the 5900-681-RC directly replace the IHD3EB681L in all applications?

A: Direct substitution is valid for applications requiring 900 mA or less continuous current. Applications demanding the full 1 A rating of the IHD3EB681L require verification that the 5900-681-RC's 900 mA rating meets system requirements.

Q: What are the physical compatibility considerations?

A: Both components use identical axial through-hole mounting and package configuration. Dimensional differences are minimal (0.460" versus 0.453" diameter), presenting no practical PCB layout constraints.

Q: How do the DC resistance values affect circuit performance?

A: The 5900-681-RC exhibits lower DC resistance (515 mOhm Max) compared to the IHD3EB681L (570 mOhm Max), resulting in reduced resistive losses and lower heat dissipation in the substitute part.

Q: Are there temperature range limitations for substitution?

A: The IHD3EB681L operates to 125°C, while the 5900-681-RC operates to 105°C. Applications requiring operation above 105°C must use the IHD3EB681L.

Q: Do inductance tolerance differences impact substitution?

A: The 5900-681-RC provides tighter tolerance (±10%) compared to the IHD3EB681L (±15%), offering improved inductance accuracy. This represents an advantage for precision circuit applications.
