Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IHD3EB680L is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value of 68 µH at 1 kHz test frequency
• Unshielded drum core wirewound construction with ferrite core material
• Through-hole axial mounting configuration
• Operating temperature range that encompasses or exceeds -55°C to 125°C
• ROHS3 compliance and REACH unaffected status

Mechanical Compatibility Criteria:

• Axial package / case format
• Physical dimensions compatible with through-hole PCB mounting
• Bulk or tray packaging suitable for production assembly

Performance Tolerance Criteria:

• Current rating of 2.5 A or higher
• DC resistance (DCR) at or below 59 mOhm maximum
• Saturation current (Isat) at or above 2.1 A

The substitute part 5900-680-RC from Bourns Inc. meets all substitution criteria within these parameter boundaries.

Parameter Comparison

Engineering Selection Recommendations

The 5900-680-RC from Bourns Inc. is a qualified substitute for the IHD3EB680L based on the following factors:

Electrical Performance: Both components deliver 68 µH inductance at 1 kHz with ferrite drum core construction. The substitute part provides superior current handling (2.8 A vs. 2.5 A) and lower DC resistance (56 mOhm vs. 59 mOhm maximum), resulting in reduced power dissipation in the circuit.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting environmental and regulatory requirements for production applications.

Mechanical Compatibility: Axial through-hole mounting and physical dimensions are compatible with standard PCB layouts. The substitute part dimensions (0.453" diameter vs. 0.460" diameter) present no mechanical interference.

Temperature Consideration: The substitute part operates to 105°C maximum, compared to 125°C for the original part. Applications requiring operation above 105°C must retain the IHD3EB680L.

Packaging Availability: The substitute is available in tray packaging with 2617 pieces in stock, compared to 815 pieces of the original in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the 5900-680-RC replace the IHD3EB680L in all applications?

A: The 5900-680-RC is electrically and mechanically compatible for applications operating at or below 105°C. Applications requiring operation above 105°C must use the IHD3EB680L, which is rated to 125°C.

Q: What is the significance of the lower DC resistance in the substitute part?

A: The 5900-680-RC has a maximum DC resistance of 56 mOhm compared to 59 mOhm for the IHD3EB680L. Lower DC resistance reduces resistive losses and heat generation in the inductor during operation at rated current levels.

Q: Are the physical dimensions interchangeable?

A: Yes. The substitute part measures 0.453" diameter versus 0.460" diameter for the original, with identical 0.900" length. Both fit standard through-hole PCB layouts without modification.

Q: Does the tighter inductance tolerance of the substitute part affect compatibility?

A: The 5900-680-RC has ±10% tolerance versus ±15% for the IHD3EB680L. Tighter tolerance provides better circuit performance consistency and does not create compatibility issues.

Q: What is the difference in current rating between these parts?

A: The IHD3EB680L is rated for 2.5 A continuous current with 2.1 A saturation current. The 5900-680-RC is rated for 2.8 A continuous current with 3.2 A saturation current. The substitute part provides higher current capacity without performance degradation.

Q: Are both parts suitable for high-frequency applications?

A: Both components are tested at 1 kHz inductance frequency. Self-resonant frequency data is not provided for either part. Frequency-dependent performance must be verified through component datasheets for applications above 1 kHz.

Q: What packaging format should be selected for production?

A: The IHD3EB680L is supplied in bulk packaging; the 5900-680-RC is supplied in tray packaging. Tray packaging is standard for automated assembly processes. Bulk packaging may be preferred for manual assembly or lower-volume applications.
