Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IHD3EB221L is determined by the following critical parameters:

• Inductance Value: 220 µH (tolerance range ±10% to ±15% acceptable)
• Current Rating: Minimum 1.5 A (substitute must support application current requirements)
• Core Type: Drum core, wirewound, ferrite material
• Mounting Configuration: Through-hole axial package
• DC Resistance: Maximum 185 mOhm (within acceptable operating limits)
• Operating Temperature: Minimum -55°C to 105°C (covers standard industrial range)
• Compliance: ROHS3 compliant, REACH unaffected

The substitute part 5900-221-RC from Bourns Inc. meets these criteria with equivalent inductance, compatible current ratings, matching core construction, and identical mounting type.

Parameter Comparison

Engineering Selection Recommendations

Both the IHD3EB221L and 5900-221-RC are active production components with ROHS3 compliance and REACH unaffected status, suitable for current industrial applications. The IHD3EB221L provides a wider operating temperature range (-55°C to 125°C) and lower DC resistance (162 mOhm max), making it preferable for high-temperature or low-loss applications. The 5900-221-RC offers tighter inductance tolerance (±10% vs ±15%) and higher saturation current (1.8 A vs 1.2 A), advantageous for applications requiring precision inductance or higher transient current handling. Physical dimensions are nearly identical, ensuring PCB layout compatibility. Selection between these parts should be based on specific application requirements for temperature range, tolerance precision, and current handling characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 5900-221-RC directly replace the IHD3EB221L in all applications?

A: Direct substitution is possible for applications operating within -55°C to 105°C. Applications requiring operation above 105°C must use the IHD3EB221L. Both parts share identical inductance values, core construction, and axial through-hole mounting, ensuring mechanical and electrical compatibility within their respective temperature ranges.

Q: What is the impact of the 23 mOhm difference in DC resistance between these parts?

A: The IHD3EB221L has 162 mOhm maximum DCR while the 5900-221-RC has 185 mOhm maximum DCR. This 23 mOhm difference results in approximately 14% higher resistive losses in the Bourns part. For applications sensitive to power dissipation or operating at maximum rated current, the Vishay Dale part is preferred.

Q: Are the physical dimensions compatible for PCB mounting?

A: Yes. Both parts are axial through-hole components with 0.900" length. The diameter difference (0.460" vs 0.453") is negligible for standard PCB hole spacing and does not affect mounting compatibility.

Q: Which part offers better inductance accuracy?

A: The 5900-221-RC provides ±10% tolerance compared to the IHD3EB221L's ±15% tolerance. For applications requiring tighter inductance specifications, the Bourns part is the better choice.

Q: What is the significance of the saturation current difference?

A: The 5900-221-RC has higher saturation current (1.8 A vs 1.2 A). This means the Bourns part maintains inductance stability at higher transient currents. For applications with current spikes or transient events, the 5900-221-RC provides better performance margin.
