LD2-470-R Equivalent & Substitute Parts

Part Overview

The LD2-470-R is a 47 µH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division. This surface mount component is rated for 2.25 A continuous current with a maximum DC resistance of 180 mOhm and operates across the temperature range of -40°C to 125°C. The part is actively produced and RoHS compliant, making it suitable for modern electronic applications requiring fixed inductance in compact form factors.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances. The SDR0805-470KL from Bourns Inc. represents an alternative source for applications where the primary part is unavailable or where packaging format flexibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LD2-470-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 47 µH ±10%
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Surface Mount
• Operating temperature range: -40°C to 125°C minimum

Secondary Compatibility Factors:

• DC resistance within acceptable limits for the application
• Current rating sufficient for circuit requirements
• RoHS compliance status
• Moisture sensitivity level (MSL 1 or equivalent)

The SDR0805-470KL meets the primary matching criteria with identical inductance, core material, shielding, and temperature range. Differences in current rating and DC resistance must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

LD2-470-R Selection Criteria:

• Applications requiring 2.25 A continuous current capacity
• Circuits where DC resistance must not exceed 180 mOhm
• Tape & Reel packaging format requirement
• Eaton component qualification or supply chain preference

SDR0805-470KL Selection Criteria:

• Applications with maximum current requirements of 1 A or less
• Circuits tolerant of up to 200 mOhm DC resistance
• Cut Tape or Digi-Reel packaging format compatibility
• Bourns component qualification or supply chain preference
• Situations where the primary part is unavailable

Both parts maintain active product status and full RoHS compliance. Selection between these components must be based on the specific circuit current requirements and DC resistance tolerance of the application. The SDR0805-470KL is not suitable as a direct substitute in circuits requiring the full 2.25 A current rating of the LD2-470-R.

Frequently Asked Questions (FAQ)

Q: Can the SDR0805-470KL replace the LD2-470-R in all applications?

A: No. The SDR0805-470KL has a maximum current rating of 1 A, compared to the LD2-470-R's 2.25 A rating. Substitution is only valid for circuits operating at 1 A or below. Exceeding this current limit will cause the substitute part to saturate prematurely and degrade circuit performance.

Q: What is the difference in DC resistance between these parts?

A: The LD2-470-R has a maximum DC resistance of 180 mOhm, while the SDR0805-470KL is rated at 200 mOhm maximum. This 20 mOhm difference may affect power dissipation and circuit efficiency in applications sensitive to inductor losses.

Q: Are the physical dimensions compatible?

A: Both parts are surface mount inductors with similar footprints. The LD2-470-R measures 0.307" L x 0.276" W (7.80mm x 7.00mm) with a height of 0.197" (5.00mm). The SDR0805-470KL measures 0.307" L x 0.307" W (7.80mm x 7.80mm) with a height of 0.209" (5.30mm). While footprints are comparable, the SDR0805-470KL is slightly larger in width and height. PCB layout verification is necessary before substitution.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the LD2-470-R and SDR0805-470KL are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What packaging formats are available for each part?

A: The LD2-470-R is supplied in Tape & Reel (TR) format. The SDR0805-470KL is available in Cut Tape (CT) and Digi-Reel® formats. Packaging selection depends on assembly process requirements and volume considerations.

Q: Are both parts RoHS compliant?

A: Yes. The LD2-470-R is RoHS Compliant. The SDR0805-470KL is ROHS3 Compliant. Both meet current RoHS requirements for electronic component manufacturing.
