DRQ125-820-R Equivalent & Substitute Parts

Part Overview

The DRQ125-820-R is a shielded 2-coil inductor array manufactured by Eaton - Electronics Division. This surface mount component operates across a temperature range of -40°C to 125°C and is ROHS3 compliant. The part is currently in active product status with 732 pieces available in inventory. The DRQ125-820-R provides dual inductance configurations: 86.89 µH in parallel connection and 347.6 µH in series connection, making it suitable for applications requiring flexible inductance selection within a single package footprint.

Identification of equivalent and substitute parts becomes necessary when primary component availability is limited, when design requirements permit parameter tolerance variations, or when supply chain optimization is required without compromising electrical performance within specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the SRF1260-820M be used as a direct replacement for the DRQ125-820-R in all applications?

A: The SRF1260-820M meets all electrical and mechanical substitution criteria. The inductance values in both parallel (82 µH vs 86.89 µH) and series (328 µH vs 347.6 µH) configurations fall within the ±20% tolerance specification. Current ratings, saturation characteristics, and DC resistance values are identical or within acceptable limits. The package footprint is compatible with a negligible height difference of 0.20 mm.

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

A: The primary electrical differences are inductance values and DC resistance specifications. The SRF1260-820M exhibits slightly lower inductance in both configurations (82 µH parallel vs 86.89 µH, and 328 µH series vs 347.6 µH) and higher maximum DC resistance (150 mOhm parallel vs 128 mOhm, and 568 mOhm series vs 515 mOhm). These differences remain within the ±20% tolerance band and do not affect functional compatibility.

Q: Are there any mechanical compatibility concerns with the SRF1260-820M?

A: Both components share identical footprint dimensions of 12.50 mm x 12.50 mm. The height difference is 0.20 mm (6.20 mm vs 6.00 mm), which is negligible for standard PCB assembly processes and does not present mechanical interference issues in typical applications.

Q: Do both parts meet the same compliance and environmental standards?

A: Both the DRQ125-820-R and SRF1260-820M are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. Both operate across the identical temperature range of -40°C to 125°C. The SRF1260-820M additionally carries REACH unaffected status.

Q: What is the significance of the ±20% tolerance specification?

A: The ±20% tolerance indicates the acceptable variation range for inductance values from the nominal specification. For the DRQ125-820-R parallel configuration (86.89 µH), acceptable values range from 69.51 µH to 104.27 µH. The SRF1260-820M at 82 µH falls within this range. This tolerance specification is standard for inductor arrays and permits substitution between parts with inductance values within this band.

Q: How do the current ratings compare between these components?

A: Both parts have identical current ratings: 2.05 A in parallel configuration and 1.03 A in series configuration. Current saturation values are also identical at 2.39 A (parallel) and 1.2 A (series). This ensures equivalent performance under load conditions.

Q: What packaging considerations apply to these parts?

A: Both components are supplied in Tape & Reel (TR) format suitable for automated assembly processes. The identical footprint and compatible height ensure seamless integration into existing pick-and-place programming and PCB layouts.
