LD2-150-R Equivalent & Substitute Parts

Part Overview

The LD2-150-R is a 15 µH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division. This surface mount component is rated for 3.38 A continuous current with a maximum DC resistance of 90 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 needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LD2-150-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 15 µH with ±20% tolerance
• Core type: Ferrite drum core, wirewound, unshielded
• DC Resistance: 90 mOhm maximum
• Operating temperature range: -40°C to 125°C
• Mounting: Surface mount, nonstandard package
• RoHS compliance status

Secondary Consideration:

• Current rating must not exceed the application requirement; lower current ratings indicate more conservative thermal performance but may limit maximum load capacity

The SDR0805-150ML from Bourns Inc. meets the primary electrical specifications (inductance, tolerance, core material, DCR, temperature range, and RoHS compliance) and shares identical surface mount nonstandard packaging. The substitute part carries a lower continuous current rating of 1.8 A compared to the main part's 3.38 A, which restricts its use to applications requiring ≤1.8 A continuous current.

Parameter Comparison

Engineering Selection Recommendations

LD2-150-R Selection Criteria: The LD2-150-R is the primary choice for applications requiring continuous current loads up to 3.38 A. This part maintains active product status with RoHS Compliant certification and demonstrates established supply availability (744 pcs in stock).

SDR0805-150ML Selection Criteria: The SDR0805-150ML from Bourns Inc. is suitable for applications with continuous current requirements not exceeding 1.8 A. This substitute carries ROHS3 Compliant status and demonstrates higher inventory availability (5000 pcs in stock). The substitute part exhibits slightly increased physical height (5.30mm vs. 5.00mm) and width (7.80mm vs. 7.00mm), which must be verified against PCB layout constraints.

Both parts maintain identical operating temperature ranges, inductance values, tolerance specifications, and DC resistance ratings. Selection between these parts is determined by the application's maximum continuous current requirement and available PCB space for component placement.

Frequently Asked Questions (FAQ)

Q: Can SDR0805-150ML replace LD2-150-R in all applications?

A: No. The SDR0805-150ML is limited to applications with continuous current ≤1.8 A. Applications requiring the full 3.38 A rating of the LD2-150-R cannot use the substitute part.

Q: Are the physical dimensions compatible between these parts?

A: Both parts use nonstandard surface mount packages with similar footprints. However, the SDR0805-150ML is 0.3mm taller (5.30mm vs. 5.00mm) and 0.8mm wider (7.80mm vs. 7.00mm). PCB layout and clearance requirements must be evaluated before substitution.

Q: Do both parts meet RoHS requirements?

A: Yes. The LD2-150-R is RoHS Compliant, and the SDR0805-150ML is ROHS3 Compliant. Both satisfy RoHS directives.

Q: What is the inductance tolerance for both parts?

A: Both the LD2-150-R and SDR0805-150ML carry ±20% inductance tolerance at their respective test frequencies (100 kHz and 1 kHz).

Q: Are moisture sensitivity levels identical?

A: Yes. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture precautions are required during storage or handling.

Q: What determines DC resistance equivalence?

A: Both parts specify 90 mOhm maximum DC resistance, ensuring equivalent power dissipation characteristics at rated current levels within their respective current ratings.
