IHD1EB221L Equivalent & Substitute Parts

Part Overview

The IHD1EB221L is a 220 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, rated for 700 mA continuous current with a maximum DC resistance of 505 mOhm. This through-hole axial component operates across the temperature range of -55°C to 125°C and is ROHS3 compliant. The part is currently active in production with 833 pieces available in stock. Substitute parts are identified when equivalent inductance values, core materials, mounting types, and electrical performance parameters align within acceptable tolerances for the application.

Substitute Part Grouping Explanation

Substitution eligibility for the IHD1EB221L is determined by the following criteria:

• Inductance Value: Must be 220 µH (exact match)
• Core Type: Must be ferrite drum core wirewound construction
• Shielding: Must be unshielded
• Mounting: Must be through-hole axial configuration
• Current Rating: Substitute must support the application's required current without saturation
• DC Resistance: Must be within acceptable limits for the circuit design
• Temperature Range: Must cover or exceed the operating environment
• Compliance: Must maintain ROHS3 compliance status

The substitute part 5800-221-RC from Bourns Inc. meets these core criteria with matching inductance, core material, shielding type, and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the IHD1EB221L and 5800-221-RC are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific current requirements:

• IHD1EB221L is suitable for applications requiring the full 700 mA continuous current rating with lower DC resistance (505 mOhm max) and extended temperature operation to 125°C.
• 5800-221-RC is suitable for applications with maximum continuous current requirements of 500 mA or less, offering tighter inductance tolerance (±10% vs ±15%) and higher saturation current (800 mA vs 490 mA).

Both components share identical inductance values, ferrite core construction, unshielded configuration, and through-hole axial mounting. Physical dimensions are comparable with minimal variation (0.270" vs 0.275" diameter). The operating temperature range difference (-55°C to 105°C for the substitute vs -55°C to 125°C for the main part) must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5800-221-RC replace the IHD1EB221L in all applications?

A: Substitution is valid only when the application's continuous current requirement does not exceed 500 mA. If the circuit requires the full 700 mA rating of the IHD1EB221L, the 5800-221-RC is not suitable. Additionally, if operation above 105°C is required, the IHD1EB221L must be used.

Q: What is the significance of the different DC resistance values?

A: The IHD1EB221L has a maximum DCR of 505 mOhm, while the 5800-221-RC has 580 mOhm. Higher DC resistance increases power dissipation in the inductor. Circuit designs sensitive to resistive losses should account for this 75 mOhm difference.

Q: Are the physical dimensions compatible for PCB layout?

A: Both components are axial through-hole parts with 0.700" length. The diameter difference (0.270" vs 0.275") is minimal and typically accommodates standard PCB hole spacing. Verify specific board layout constraints before substitution.

Q: What does the inductance tolerance difference mean for circuit performance?

A: The 5800-221-RC offers ±10% tolerance compared to the IHD1EB221L's ±15%. Tighter tolerance may benefit circuits where inductance precision is critical, though both fall within standard wirewound inductor specifications.

Q: Are both parts compliant with current regulations?

A: Yes. Both the IHD1EB221L and 5800-221-RC are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
