Key Parameters

Substitute Part Grouping Explanation

Substitution of the SD10-150-R is determined by alignment of the following critical parameters:

Primary Substitution Criteria:

• Inductance value: 15 µH (exact match required)
• Core type: Drum core, wirewound, ferrite material
• Shielding: Shielded configuration
• Mounting: Surface mount technology
• Current rating: Minimum 613 mA continuous current capability
• DC resistance: Comparable performance within acceptable tolerance
• Operating temperature range: Minimum coverage of -40°C to 85°C
• Regulatory compliance: RoHS status

The SRR4011-150YL from Bourns Inc. meets these substitution criteria with equivalent inductance, core construction, shielding, and mounting characteristics. The substitute part provides enhanced current rating (900 mA) and extended temperature range (-40°C to 125°C), supporting broader application flexibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SD10-150-R and SRR4011-150YL are Active products with current manufacturing status and full regulatory compliance. The SD10-150-R maintains RoHS Compliant certification, while the SRR4011-150YL carries ROHS3 Compliant status, indicating alignment with current environmental regulations.

Selection between these parts is based on application-specific requirements:

Select SD10-150-R when:

• Exact inductance tolerance of ±20% is required
• Operating temperature range does not exceed 85°C
• DC resistance specification of 442.9 mOhm is critical
• Original design specifications mandate Eaton components
• Saturation current of 605 mA is sufficient

Select SRR4011-150YL when:

• Higher current rating (900 mA) provides design margin
• Extended temperature range (-40°C to 125°C) is required
• Lower DC resistance (400 mOhm max) reduces power dissipation
• ROHS3 compliance is specified
• Slightly smaller footprint (4.80mm vs 5.20mm) supports space-constrained layouts
• Higher saturation current (700 mA) is beneficial

Both parts are surface mount, shielded, ferrite drum core inductors tested at 100 kHz with unlimited moisture sensitivity rating. Mechanical compatibility requires verification of PCB pad layout and height clearance due to dimensional differences.

Frequently Asked Questions (FAQ)

Q: Can the SRR4011-150YL directly replace the SD10-150-R in all applications?

A: The SRR4011-150YL is electrically compatible for applications where the SD10-150-R operates. The substitute part meets or exceeds the primary electrical specifications (inductance, current rating, saturation current, and DC resistance). However, PCB layout verification is required due to dimensional differences: the SRR4011-150YL is 0.189" x 0.189" (4.80mm x 4.80mm) versus the SD10-150-R at 0.205" x 0.205" (5.20mm x 5.20mm), and height differs by 0.012" (0.30mm).

Q: What is the significance of the inductance tolerance difference (±20% vs ±30%)?

A: The SD10-150-R specifies ±20% tolerance, providing tighter inductance control. The SRR4011-150YL specifies ±30% tolerance, allowing wider variation. Applications requiring precise inductance values should account for this difference in circuit design and performance analysis.

Q: Are there temperature range limitations when substituting?

A: The SD10-150-R operates from -40°C to 85°C. The SRR4011-150YL extends this range to -40°C to 125°C. If the application operates above 85°C, only the SRR4011-150YL is suitable. For applications within the -40°C to 85°C range, both parts are compatible.

Q: How does the DC resistance difference affect circuit performance?

A: The SD10-150-R specifies 442.9 mOhm DCR, while the SRR4011-150YL specifies 400 mOhm maximum. Lower DC resistance reduces power dissipation and heat generation. For high-current or thermally sensitive applications, the SRR4011-150YL provides improved efficiency.

Q: What packaging considerations apply to these parts?

A: Both parts are supplied in Tape & Reel (TR) packaging for automated assembly. Both carry MSL 1 (Unlimited) moisture sensitivity rating, eliminating bake-out requirements. Verify that your assembly equipment is compatible with the nonstandard package dimensions.

Q: Are both parts RoHS compliant?

A: Yes. The SD10-150-R is RoHS Compliant. The SRR4011-150YL is ROHS3 Compliant, representing current environmental regulation standards. Both parts meet RoHS requirements for lead-free and restricted substance compliance.

Q: What is the saturation current specification and why does it matter?

A: Saturation current (Isat) indicates the current level at which the inductor begins to lose inductance due to core saturation. The SD10-150-R has Isat of 605 mA, while the SRR4011-150YL has Isat of 700 mA. Applications with current transients or peak currents approaching these levels require careful evaluation to maintain inductance stability.
