SRF2012-221YA Equivalent & Substitute Parts

Part Overview

The SRF2012-221YA is a 2-line common mode choke (CMC) manufactured by Bourns Inc., designed for surface mount applications. This component provides 220 ohms of impedance at 100 MHz with a maximum current rating of 300mA and operates across the temperature range of -40°C to 125°C. The part is currently in active production status with full RoHS3 compliance and REACH unaffected certification. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Substitute Part Grouping Explanation

Substitution of the SRF2012-221YA is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Impedance of 220 Ohms @ 100 MHz, current rating of 300mA, and DC resistance (DCR) maximum of 400mOhm
• Physical Compatibility: Surface mount configuration with identical footprint dimensions of 0.079" L x 0.047" W (2.00mm x 1.20mm) and 4-pad horizontal package case
• Functional Architecture: 2-line common mode choke topology
• Environmental Compliance: RoHS3 compliance and REACH unaffected status
• Operating Range: Temperature range of -40°C to 125°C

The substitute part CM0805C221R-10 meets all these criteria and is therefore electrically and mechanically interchangeable with the SRF2012-221YA.

Parameter Comparison

Engineering Selection Recommendations

Both the SRF2012-221YA and CM0805C221R-10 are active production components with full regulatory compliance. Selection between these parts should be based on:

• Availability and Lead Time: Verify current inventory levels and delivery schedules with your supplier
• Packaging Format: The SRF2012-221YA is supplied in Tape & Reel (TR) format, while the CM0805C221R-10 is available in Cut Tape (CT) & Digi-Reel® format. Confirm packaging compatibility with your assembly process
• Moisture Sensitivity: The SRF2012-221YA has MSL 1 (Unlimited), while the CM0805C221R-10 is listed as Not Applicable. Verify storage and handling requirements for your manufacturing environment
• Cost and Volume Requirements: Compare unit pricing and minimum order quantities for your procurement needs

Both parts satisfy identical electrical and mechanical requirements and are suitable for direct substitution in applications requiring 2-line common mode chokes with 220 ohms impedance at 100 MHz and 300mA current capacity.

Frequently Asked Questions (FAQ)

Q: Can CM0805C221R-10 be used as a direct replacement for SRF2012-221YA?

A: Yes. Both components share identical electrical specifications (220 Ohms @ 100 MHz, 300mA, 400mOhm DCR), physical dimensions (2.00mm x 1.20mm), and package configuration (Horizontal, 4 PC Pad). They are electrically and mechanically interchangeable.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Bourns vs. Laird), packaging format (Tape & Reel vs. Cut Tape & Digi-Reel), and moisture sensitivity level designation. Electrical performance and physical footprint are identical.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS3 compliant and REACH unaffected. No compliance differences exist between the two components.

Q: Does packaging format affect circuit performance?

A: No. Packaging format (Tape & Reel vs. Cut Tape) affects only procurement and assembly logistics, not electrical or mechanical performance. The components themselves are identical.

Q: What should I verify before switching to the substitute part?

A: Confirm that your assembly equipment is compatible with the substitute part's packaging format (Cut Tape & Digi-Reel vs. Tape & Reel) and verify any specific moisture handling requirements for your manufacturing process.
