LD2-220-R Equivalent & Substitute Parts

Part Overview

The LD2-220-R is a 22 µH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division. This surface mount component is designed for applications requiring fixed inductance with a current rating of 3.13 A and maximum DC resistance of 110mOhm. The part is currently in active production status with RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when the main part becomes unavailable, when inventory constraints require alternative sourcing, or when application requirements permit operation within the electrical and mechanical parameters of qualified alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LD2-220-R is determined by the following critical parameters:

Inductance Value: The substitute part must provide 22 µH inductance within the ±20% tolerance band (17.6 µH to 26.4 µH).

DC Resistance: The substitute part must maintain DC resistance at or below 110mOhm maximum to ensure equivalent power dissipation characteristics.

Core Type and Shielding: The substitute must use ferrite drum core construction with unshielded configuration to maintain electromagnetic compatibility with the original design.

Current Rating: The substitute part must support the application's maximum current requirement. Parts with lower current ratings may be used only in applications where the actual operating current does not exceed the substitute's rating.

Temperature Range: The substitute must operate across the -40°C to 125°C range to ensure thermal compatibility.

Mounting and Package: Surface mount configuration with nonstandard package dimensions must be maintained for PCB assembly compatibility.

Compliance: RoHS compliance and MSL 1 rating are required for manufacturing and storage compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - LD2-220-R: Use the LD2-220-R when the application requires a current rating of 3.13 A or when Eaton component qualification is specified. This part is in active production with RoHS compliance and unlimited MSL rating.

Substitute Selection - SDR0805-220ML: The Bourns SDR0805-220ML qualifies as a substitute when the application's actual operating current does not exceed 1.5 A. Both parts share identical inductance (22 µH), tolerance (±20%), DC resistance (110mOhm max), core material (ferrite), shielding (unshielded), temperature range (-40°C to 125°C), and compliance status (RoHS and MSL 1). The SDR0805-220ML is in active production status. Physical dimensions are similar with minor width variation (7.00mm vs 7.80mm) and negligible height difference (5.00mm vs 5.30mm), permitting PCB layout compatibility in most applications.

Current Rating Constraint: The SDR0805-220ML current rating of 1.5 A is lower than the LD2-220-R rating of 3.13 A. Substitution is valid only when application design confirms maximum operating current remains below 1.5 A.

Compliance Verification: Both parts maintain RoHS compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the SDR0805-220ML replace the LD2-220-R in all applications?

A: No. The SDR0805-220ML has a current rating of 1.5 A compared to the LD2-220-R rating of 3.13 A. Substitution is valid only when the application's maximum operating current does not exceed 1.5 A. If the circuit requires current above 1.5 A, the LD2-220-R must be used.

Q: Are the physical dimensions compatible for PCB assembly?

A: The parts have similar but not identical dimensions. The LD2-220-R measures 7.80mm L x 7.00mm W x 5.00mm H, while the SDR0805-220ML measures 7.80mm L x 7.80mm W x 5.30mm H. The width and height differences are minor. PCB layout compatibility depends on specific board design constraints. Verify footprint clearance and height restrictions before substitution.

Q: Do both parts have the same inductance and tolerance?

A: Yes. Both the LD2-220-R and SDR0805-220ML provide 22 µH inductance with ±20% tolerance, ensuring equivalent inductance performance.

Q: Is the DC resistance the same for both parts?

A: Yes. Both parts specify 110mOhm maximum DC resistance, providing identical power dissipation characteristics.

Q: What is the temperature operating range for both parts?

A: Both parts operate across -40°C to 125°C, ensuring thermal compatibility in equivalent applications.

Q: Are both parts RoHS compliant?

A: Yes. The LD2-220-R is RoHS Compliant, and the SDR0805-220ML is ROHS3 Compliant. Both meet RoHS requirements for manufacturing and environmental compliance.

Q: What does MSL 1 rating mean for these parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life with no moisture precautions required during storage or handling. Both parts carry this rating.

Q: Can I use the SDR0805-220ML if my application requires 2.5 A?

A: No. The SDR0805-220ML current rating is 1.5 A. Operating at 2.5 A exceeds the part's specification and may cause thermal stress or failure. The LD2-220-R with its 3.13 A rating is required for this application.

Q: Are the saturation currents equivalent?

A: The saturation currents are similar but not identical. The LD2-220-R has Isat of 2.45 A, while the SDR0805-220ML has Isat of 2.3 A. Both values are close, but the LD2-220-R provides slightly higher saturation margin.
