Key Parameters

Substitute Part Grouping Explanation

Substitution of the DRQ127-8R2-R is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Number of coils: 2 coils (fixed requirement)
• Inductance values in parallel and series configurations must fall within acceptable tolerance ranges for the application
• Current rating in parallel configuration must meet or exceed 6.32 A
• DC resistance characteristics must be compatible with circuit performance requirements
• Operating temperature range must encompass -40°C to 125°C

Mechanical Compatibility Criteria:

• Mounting type: Surface Mount (fixed requirement)
• Physical footprint: 12.50mm x 12.50mm base dimension (fixed requirement)
• Shielding: Shielded construction (fixed requirement)
• Packaging format: Tape & Reel (TR)

Compliance Criteria:

• RoHS3 Compliance (mandatory)
• Moisture Sensitivity Level 1 (Unlimited)

The SRF1260-8R2Y from Bourns Inc. qualifies as a substitute based on these parameters. Both parts share identical coil count, shielding type, mounting method, footprint dimensions, operating temperature range, and compliance certifications. Inductance values and current ratings differ within acceptable engineering tolerances for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both the DRQ127-8R2-R and SRF1260-8R2Y maintain Active product status with full RoHS3 compliance and MSL Level 1 rating, ensuring long-term availability and environmental regulatory adherence. The DRQ127-8R2-R offers tighter inductance tolerance (±20% versus ±30%) and higher current ratings in both parallel (6.32 A versus 5.54 A) and series (3.16 A versus 2.77 A) configurations. The SRF1260-8R2Y provides a lower profile height (6.20mm versus 8.00mm), which may be advantageous in space-constrained applications. Both components share identical footprint dimensions (12.50mm x 12.50mm), shielding characteristics, and operating temperature specifications, supporting direct substitution in circuit designs where the specified electrical parameters are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the SRF1260-8R2Y directly replace the DRQ127-8R2-R in existing designs?

A: Direct substitution is possible when the application circuit tolerates the parameter differences. The SRF1260-8R2Y delivers 8.2 µH parallel inductance (versus 8.861 µH) and 5.54 A parallel current rating (versus 6.32 A). Circuit simulation or testing is required to confirm performance acceptability for specific applications.

Q: What are the key mechanical compatibility factors?

A: Both parts share identical footprint dimensions (12.50mm x 12.50mm), surface mount configuration, and Tape & Reel packaging. The SRF1260-8R2Y has a lower profile (6.20mm height versus 8.00mm), which may affect PCB layout clearances in height-restricted designs.

Q: How do tolerance specifications affect substitution?

A: The DRQ127-8R2-R specifies ±20% inductance tolerance, while the SRF1260-8R2Y specifies ±30%. Applications requiring tighter inductance control may require the DRQ127-8R2-R. Applications with broader tolerance margins can accommodate the SRF1260-8R2Y.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the DRQ127-8R2-R and SRF1260-8R2Y are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.

Q: What is the significance of the current saturation ratings?

A: Current saturation indicates the threshold at which inductance begins to degrade. The DRQ127-8R2-R saturates at 12.2 A (parallel), while the SRF1260-8R2Y saturates at 7.89 A (parallel). Applications operating near maximum current levels must account for this difference.

Q: How do DC resistance values impact circuit performance?

A: The DRQ127-8R2-R exhibits 15.7 mOhm parallel DCR, while the SRF1260-8R2Y exhibits 19.4 mOhm maximum. Higher DCR increases power dissipation and heat generation. Applications sensitive to resistive losses should evaluate this parameter.
