LD2-100-R Equivalent & Substitute Parts

Part Overview

The LD2-100-R is a 10 µH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division. This surface mount component is rated for 3.83 A continuous current with a maximum DC resistance of 70 mOhm and operates across the temperature range of -40°C to 125°C. The part is RoHS Compliant and carries an Active product status. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or application-specific packaging preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LD2-100-R is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value of 10 µH with ±20% tolerance
• DC resistance of 70 mOhm maximum
• Ferrite drum core construction with wirewound configuration
• Unshielded design
• Operating temperature range of -40°C to 125°C

Mechanical Compatibility Requirements:

• Surface mount packaging
• Nonstandard package case dimensions compatible with board layout

The SDR0805-100ML from Bourns Inc. meets these core electrical and mechanical criteria. However, the substitute part exhibits a reduced current rating of 2.3 A compared to the main part's 3.83 A specification. This difference must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

LD2-100-R Selection Criteria: The LD2-100-R is appropriate for applications requiring the full 3.83 A current rating. This part maintains Active product status and RoHS Compliance certification. Selection is recommended when current capacity is a critical design parameter and the specified current rating cannot be reduced.

SDR0805-100ML Selection Criteria: The SDR0805-100ML is appropriate for applications where the 2.3 A current rating is sufficient for circuit operation. This part carries ROHS3 Compliance and REACH Unaffected status, providing enhanced regulatory documentation. The substitute part is suitable when current requirements do not exceed 2.3 A and alternative packaging formats (Cut Tape & Digi-Reel) are acceptable.

Both parts share identical inductance values, tolerance specifications, DC resistance ratings, core materials, shielding characteristics, and operating temperature ranges. Selection between these parts is determined by application current requirements and packaging preferences.

Frequently Asked Questions (FAQ)

Q: Can the SDR0805-100ML replace the LD2-100-R in all applications?

A: The SDR0805-100ML is electrically equivalent in inductance, tolerance, DC resistance, and temperature range. However, the substitute part has a maximum current rating of 2.3 A compared to the LD2-100-R's 3.83 A rating. Substitution is valid only when circuit current requirements do not exceed 2.3 A.

Q: What are the key electrical differences between these parts?

A: The primary electrical difference is the current rating: LD2-100-R is rated for 3.83 A while SDR0805-100ML is rated for 2.3 A. Both parts share identical inductance (10 µH), tolerance (±20%), DC resistance (70 mOhm max), core material (ferrite), and operating temperature range (-40°C to 125°C).

Q: Are there packaging differences between these parts?

A: Yes. The LD2-100-R is supplied in Tape & Reel (TR) packaging, while the SDR0805-100ML is supplied in Cut Tape (CT) & Digi-Reel format. Physical dimensions differ slightly: LD2-100-R measures 0.307" L x 0.276" W x 0.197" H (max), while SDR0805-100ML measures 0.307" L x 0.307" W x 0.209" H (max).

Q: Do both parts meet RoHS requirements?

A: Yes. The LD2-100-R is RoHS Compliant. The SDR0805-100ML is ROHS3 Compliant, which represents an updated compliance standard. Both parts are suitable for RoHS-regulated applications.

Q: What is the saturation current difference between these parts?

A: The LD2-100-R has a saturation current (Isat) of 3.45 A, while the SDR0805-100ML has an Isat of 3.2 A. Both values are provided for reference in high-current transient conditions.
