IHD1ER331L Equivalent & Substitute Parts

Part Overview

The IHD1ER331L is a 330 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, rated for 620 mA continuous current with a maximum DC resistance of 650 mOhm. This through-hole axial component is designed for applications requiring fixed inductance in the 330 µH range with moderate current handling capability. Substitute parts are identified based on matching inductance value, core type, mounting configuration, and electrical performance within acceptable tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IHD1ER331L are identified based on the following critical parameters:

• Inductance Value: 330 µH (primary matching criterion)
• Core Configuration: Unshielded drum core wirewound construction
• Mounting Style: Through hole axial package
• Current Handling: Rated current capacity sufficient for the application
• DC Resistance: Maximum DCR within acceptable operating limits
• Temperature Range: Operating temperature compatibility

The 5800-331-RC from Bourns Inc. qualifies as a substitute based on matching inductance, core type, and mounting configuration. Differences in current rating and DCR must be evaluated against specific application requirements.

Engineering Selection Recommendations

IHD1ER331L (Primary Part)

• Preferred for applications requiring 620 mA continuous current capacity
• Lower DC resistance (650 mOhm Max) reduces power dissipation
• Suitable for designs with higher current demands

5800-331-RC (Substitute Part)

• Applicable for applications with maximum current requirements of 400 mA or lower
• Higher DC resistance (770 mOhm Max) results in increased power dissipation; thermal management must be evaluated
• ROHS3 and REACH compliance certifications are documented
• Active product status ensures ongoing availability

Substitution is valid only when application current requirements do not exceed 400 mA continuous operation. For applications requiring the full 620 mA rating of the IHD1ER331L, the 5800-331-RC is not suitable.

Frequently Asked Questions (FAQ)

Q: Can the 5800-331-RC replace the IHD1ER331L in all applications? A: No. The 5800-331-RC has a lower current rating (400 mA vs. 620 mA). Substitution is valid only for applications where continuous current does not exceed 400 mA.

Q: What is the impact of the higher DC resistance in the 5800-331-RC? A: The 5800-331-RC has 770 mOhm Max DCR compared to 650 mOhm Max in the IHD1ER331L. This 120 mOhm difference increases resistive losses and heat generation. Power dissipation calculations must be performed for the specific application current to determine acceptability.

Q: Are both parts compatible with the same PCB footprint? A: Both parts use through-hole axial mounting. Physical dimensions must be verified: IHD1ER331L dimensions are not specified in the provided data; 5800-331-RC is 0.275" Dia x 0.700" L (6.99mm x 17.78mm). Confirm mechanical fit before substitution.

Q: What compliance certifications apply to each part? A: The 5800-331-RC is ROHS3 Compliant and REACH Unaffected. Compliance status for the IHD1ER331L is not provided in the available data.

Q: Is the ±10% inductance tolerance of the 5800-331-RC acceptable? A: Inductance tolerance acceptance depends on circuit design requirements. The ±10% specification for the 5800-331-RC must be evaluated against the application's inductance tolerance budget.
