Key Parameters

Substitute Part Grouping Explanation

Substitution of the IHD3EB103L is permissible with the Bourns Inc. 5900-103-RC based on the following criteria:

Matching Parameters:

• Inductance value: 10 mH (identical)
• Core material and type: Ferrite drum core, unshielded (identical)
• Mounting configuration: Through hole axial (identical)
• Package form factor: Axial (identical)
• Inductance test frequency: 1 kHz (identical)
• RoHS compliance: ROHS3 compliant (identical)
• REACH status: REACH unaffected (identical)

Allowable Variations:

• Current rating: 250 mA (main) vs. 230 mA (substitute) — substitute operates within acceptable margin for applications not requiring maximum current capacity
• DC resistance: 7.3 Ohm max (main) vs. 7.6 Ohm max (substitute) — variation within typical tolerance band for this component class
• Operating temperature: -55°C to 125°C (main) vs. -55°C to 105°C (substitute) — substitute suitable for applications not exceeding 105°C
• Inductance tolerance: ±15% (main) vs. ±10% (substitute) — substitute provides tighter tolerance
• Saturation current: 180 mA (main) vs. 260 mA (substitute) — substitute exhibits higher saturation margin

Parameter Comparison

Engineering Selection Recommendations

Both the IHD3EB103L and 5900-103-RC are active production components with ROHS3 compliance and REACH unaffected status, suitable for applications requiring regulatory adherence. Selection between these parts depends on application-specific constraints:

The IHD3EB103L is the primary choice for applications requiring the full 250 mA current rating and extended operating temperature to 125°C.

The 5900-103-RC is suitable as a substitute for applications with current requirements at or below 230 mA and maximum operating temperatures not exceeding 105°C. The substitute offers tighter inductance tolerance (±10% vs. ±15%) and higher saturation current margin (260 mA vs. 180 mA), which may provide performance advantages in specific circuit topologies.

Both components maintain identical inductance values, core materials, and axial through-hole mounting configurations, ensuring mechanical and electrical compatibility within the stated parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can the 5900-103-RC replace the IHD3EB103L in all applications?

A: The 5900-103-RC is suitable as a substitute only when the application current requirement does not exceed 230 mA and the maximum operating temperature does not exceed 105°C. Applications requiring the full 250 mA rating or operation above 105°C must use the IHD3EB103L.

Q: What is the impact of the 0.3 Ohm difference in DC resistance?

A: The DC resistance difference (7.3 Ohm vs. 7.6 Ohm) represents approximately 4% variation. This difference affects power dissipation and thermal performance. For applications sensitive to resistive losses, verify that the substitute's higher resistance remains acceptable for the circuit design.

Q: Are the physical dimensions compatible?

A: Both components are axial through-hole inductors with identical length (0.900" / 22.86mm). The diameter difference is minimal (0.460" vs. 0.453"), making them mechanically compatible for standard PCB layouts. Verify clearance in space-constrained designs.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the IHD3EB103L and 5900-103-RC are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory standards for electronic component use.

Q: What does the tighter tolerance of the 5900-103-RC mean?

A: The 5900-103-RC has ±10% inductance tolerance compared to ±15% for the IHD3EB103L. This means the substitute provides more precise inductance values within a narrower range, which may be beneficial for applications requiring tighter circuit performance specifications.
