SD10-2R2-R Equivalent & Substitute Parts

Part Overview

The SD10-2R2-R is a 2.2 µH shielded drum core wirewound inductor manufactured by Eaton - Electronics Division. This surface mount component is designed for applications requiring fixed inductance with controlled DC resistance and current handling capabilities. The part operates across the industrial temperature range of -40°C to 85°C and maintains active product status with full RoHS compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be achieved within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SD10-2R2-R are identified based on strict electrical and mechanical parameter alignment. The substitution logic requires:

Electrical Parameters (Non-negotiable):

• Inductance value of 2.2 µH at 100 kHz test frequency
• Shielded drum core wirewound construction with ferrite core material
• Current rating equal to or greater than 1.35 A
• DC resistance equal to or less than 91.2 mOhm
• Surface mount packaging for PCB assembly compatibility

Mechanical Parameters:

• Nonstandard package case dimensions compatible with SD10 footprint requirements
• Height seated maximum within acceptable PCB clearance limits

Compliance Parameters:

• Active product status from manufacturer
• RoHS compliance certification (RoHS or ROHS3 acceptable)
• Moisture sensitivity level 1 (unlimited reflow cycles)

The SRR4011-2R2YL from Bourns Inc. meets these substitution criteria with equivalent inductance, superior current handling, and lower DC resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - SD10-2R2-R: Select the SD10-2R2-R when the original design specifications require the exact physical footprint of 5.20mm x 5.20mm with 1.00mm maximum seated height. This part maintains active manufacturing status with RoHS compliance and meets all specified electrical requirements for the application.

Substitute Selection - SRR4011-2R2YL: The SRR4011-2R2YL from Bourns Inc. is electrically compatible as a substitute when:

• The PCB layout can accommodate the slightly smaller 4.80mm x 4.80mm footprint
• The increased height of 1.30mm does not conflict with PCB clearance requirements
• The application benefits from the superior current rating (2 A versus 1.35 A) and lower DC resistance (75 mOhm maximum versus 91.2 mOhm)
• Extended operating temperature range to 125°C is acceptable or beneficial

Both parts maintain active product status, full RoHS compliance, and unlimited moisture sensitivity rating. The substitute part provides enhanced electrical performance characteristics while maintaining the same inductance value and shielded ferrite drum core construction.

Frequently Asked Questions (FAQ)

Q: Can the SRR4011-2R2YL be used as a direct replacement for the SD10-2R2-R?

A: Electrical substitution is valid. The SRR4011-2R2YL provides equivalent 2.2 µH inductance with superior current handling and lower DC resistance. However, mechanical compatibility must be verified. The substitute is 0.4mm smaller in length and width but 0.3mm taller. PCB layout and clearance requirements must be evaluated before substitution.

Q: What are the critical parameters that must match for substitution?

A: Inductance value (2.2 µH), shielded ferrite drum core construction, surface mount packaging, and current rating equal to or exceeding 1.35 A are non-negotiable. DC resistance must not exceed 91.2 mOhm. All substitute parts must maintain active product status and RoHS compliance.

Q: Does the wider inductance tolerance of the SRR4011-2R2YL (±30% versus ±20%) affect substitution validity?

A: The substitute's wider tolerance does not prevent substitution when the application circuit design accommodates the specified tolerance range. Both parts are tested at 100 kHz. Circuit performance must be verified if the application requires inductance tolerance tighter than ±30%.

Q: Are there packaging differences between these parts?

A: The SD10-2R2-R is supplied in standard packaging, while the SRR4011-2R2YL is supplied in Tape & Reel (TR) format. Both maintain MSL 1 (unlimited) moisture sensitivity rating. Reel packaging may require different handling procedures in manufacturing environments.

Q: What is the impact of the extended operating temperature range of the SRR4011-2R2YL?

A: The SRR4011-2R2YL operates to 125°C versus 85°C for the SD10-2R2-R. This extended range does not create compatibility issues for applications operating within the original -40°C to 85°C specification. The substitute is suitable for applications requiring higher temperature operation.

Q: How do the saturation current ratings compare?

A: The SD10-2R2-R has Isat of 1.65 A, while the SRR4011-2R2YL has Isat of 1.8 A. Both provide adequate margin above their respective current ratings (1.35 A and 2 A). The substitute offers greater operating margin before saturation occurs.

Q: Are both parts RoHS compliant?

A: Yes. The SD10-2R2-R is RoHS Compliant, and the SRR4011-2R2YL is ROHS3 Compliant. Both meet current regulatory requirements for lead-free and restricted substance compliance.
