SD8350-150-R Equivalent & Substitute Parts Reference

Part Overview

The SD8350-150-R is a 15 µH shielded drum core wirewound inductor manufactured by Eaton - Electronics Division. This surface mount component is rated for 2.3 A continuous current with a maximum DC resistance of 53 mOhm and operates across the temperature range of -40°C to 125°C. The part maintains Active product status and is RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute components become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits selection from qualified alternatives meeting equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the SD8350-150-R are qualified based on the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value: 15 µH (±30% tolerance band)
• Current rating: minimum 2.3 A continuous
• DC resistance: maximum 53 mOhm
• Saturation current: minimum 2.9 A
• Core material: Ferrite
• Shielding: Shielded construction

Mechanical & Environmental Criteria:

• Mounting type: Surface Mount
• Package format: Tape & Reel (TR)
• Operating temperature range: minimum -40°C to 125°C
• Moisture sensitivity: MSL 1 (Unlimited)
• Compliance: RoHS Compliant or ROHS3 Compliant

Substitution Classification:

Direct Substitute (SRU8043-150Y): Meets or exceeds all electrical parameters with improved current rating (2.7 A) and lower DC resistance (46 mOhm). Identical inductance, tolerance, core material, and shielding. Smaller footprint (8.00mm x 8.00mm vs. 9.50mm x 8.30mm). Full temperature range coverage and ROHS3 compliance.

Similar Substitute (CDRH8D43NP-150NC): Matches electrical specifications identically (15 µH, 2.3 A, 53 mOhm DCR, 2.9 A Isat). Identical core material and shielding. Smaller footprint (8.00mm x 8.00mm). Operating temperature range limited to -40°C to 100°C (25°C reduction at upper limit). ROHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

SD8350-150-R (Primary Component): Use when Eaton supply chain availability is confirmed and design layout accommodates the larger footprint (9.50mm x 8.30mm). Maintains full temperature range to 125°C. RoHS Compliant status suitable for all regulated markets.

SRU8043-150Y (Direct Substitute - Preferred Alternative): Select when improved electrical performance is acceptable within design constraints. Superior current rating (2.7 A vs. 2.3 A) and lower DC resistance (46 mOhm vs. 53 mOhm) provide enhanced thermal margin. Smaller footprint (8.00mm x 8.00mm) enables PCB space optimization. Full temperature range (-40°C to 125°C) and ROHS3 compliance ensure regulatory alignment. Higher inventory availability (27,300 pcs) supports production schedules.

CDRH8D43NP-150NC (Similar Substitute - Conditional Use): Select only when application operating temperature does not exceed 100°C. Electrical specifications match SD8350-150-R identically. Smaller footprint (8.00mm x 8.00mm) provides PCB layout benefits. ROHS3 compliance and MSL 1 rating confirm environmental suitability. Verify thermal design does not require the extended 125°C upper limit before implementation.

Frequently Asked Questions (FAQ)

Q: Can SRU8043-150Y replace SD8350-150-R in all applications?

A: SRU8043-150Y meets or exceeds all electrical and mechanical parameters of SD8350-150-R. The improved current rating (2.7 A vs. 2.3 A) and lower DC resistance (46 mOhm vs. 53 mOhm) provide additional design margin. Both components operate across -40°C to 125°C and feature identical inductance (15 µH), tolerance (±30%), core material (Ferrite), and shielding. The smaller footprint (8.00mm x 8.00mm) requires PCB layout verification for clearance compatibility.

Q: What is the key limitation of CDRH8D43NP-150NC?

A: CDRH8D43NP-150NC operates only to 100°C maximum, compared to 125°C for SD8350-150-R and SRU8043-150Y. All other electrical parameters match SD8350-150-R identically. Applications requiring sustained operation above 100°C must use SD8350-150-R or SRU8043-150Y.

Q: Are all three components available in Tape & Reel packaging?

A: Yes. SD8350-150-R, SRU8043-150Y, and CDRH8D43NP-150NC are all supplied in Tape & Reel (TR) format suitable for automated assembly processes.

Q: Do all substitutes maintain RoHS compliance?

A: SD8350-150-R is RoHS Compliant. SRU8043-150Y and CDRH8D43NP-150NC are ROHS3 Compliant. Both compliance levels satisfy regulatory requirements for restricted substance elimination.

Q: What is the saturation current difference between SRU8043-150Y and the other parts?

A: SRU8043-150Y has a saturation current (Isat) of 2.0 A, while SD8350-150-R and CDRH8D43NP-150NC both specify 2.9 A. Applications operating near saturation limits must account for this 0.9 A difference when selecting SRU8043-150Y.

Q: How do the physical dimensions affect PCB layout?

A: SD8350-150-R measures 9.50mm x 8.30mm with 4.50mm seated height. SRU8043-150Y and CDRH8D43NP-150NC both measure 8.00mm x 8.00mm, reducing footprint area by approximately 21%. SRU8043-150Y seated height is 4.60mm (0.10mm taller), while CDRH8D43NP-150NC matches SD8350-150-R at 4.50mm. Verify clearance with adjacent components before layout finalization.

Q: What inventory considerations apply to these substitutes?

A: SD8350-150-R has 1,042 pcs in stock. SRU8043-150Y offers significantly higher availability at 27,300 pcs. CDRH8D43NP-150NC provides 5,072 pcs. For high-volume production, SRU8043-150Y availability supports extended lead time requirements.
