DRQ73-680-R Equivalent & Substitute Parts

Part Overview

The DRQ73-680-R is a shielded 2-coil inductor array manufactured by Eaton - Electronics Division, currently in active product status. This surface mount component operates across the temperature range of -40°C to 125°C and is designed for applications requiring dual-inductance configurations with selectable series and parallel connection modes. The part is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity tolerance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this inductor array category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DRQ73-680-R is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Inductance values in parallel and series configurations must fall within the ±20% tolerance band established for this product category
• Current ratings (both nominal and saturation) must equal or exceed the original part specifications in both connection modes
• DC resistance values must not exceed the original specifications to maintain thermal performance and efficiency

Mechanical Compatibility Criteria:

• Surface mount packaging with identical footprint dimensions (7.60mm x 7.60mm)
• Height tolerance within manufacturing standards for automated assembly
• Shielded construction to maintain electromagnetic isolation properties
• 2-coil array configuration with dual-inductance capability

Compliance Criteria:

• ROHS3 compliance status
• MSL 1 rating for moisture sensitivity
• Active product status from manufacturer

The SRF0703-680M from Bourns Inc. meets these substitution criteria within the established parameter windows.

Engineering Selection Recommendations

DRQ73-680-R (Eaton - Electronics Division):

• Primary selection for applications where original manufacturer specification is required
• Active product status with 2200 units in current inventory
• ROHS3 compliant with MSL 1 rating
• Lower DC resistance values in both configurations provide optimal thermal efficiency

SRF0703-680M (Bourns Inc.):

• Direct substitute when supply continuity or alternative sourcing is required
• Active product status with 15832 units in current inventory
• ROHS3 compliant with MSL 1 rating and REACH unaffected status
• Electrical parameters remain within the ±20% tolerance specification for both series and parallel configurations
• Slightly elevated DC resistance values remain within acceptable operational limits for this component category

Both parts maintain identical current ratings, saturation characteristics, and operating temperature ranges. Selection between these parts is based on supply availability, sourcing strategy, and manufacturer preference rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can the SRF0703-680M directly replace the DRQ73-680-R in existing designs?

A: Yes. Both parts share identical footprint dimensions (7.60mm x 7.60mm), surface mount packaging, and electrical specifications within the ±20% tolerance band. The inductance values in parallel (68 µH vs 68.91 µH) and series (272 µH vs 275.6 µH) configurations fall within acceptable variance. Current ratings and saturation points are identical.

Q: What is the impact of the higher DC resistance in the SRF0703-680M?

A: The SRF0703-680M exhibits maximum DC resistance of 507 mOhm (parallel) and 1.92 Ohm (series) compared to 358 mOhm and 1.43 Ohm in the DRQ73-680-R. This represents a 41% increase in parallel configuration and 34% increase in series configuration. Applications sensitive to resistive losses should evaluate thermal performance impact in their specific circuit conditions.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both the DRQ73-680-R and SRF0703-680M operate across the identical temperature range of -40°C to 125°C, meeting standard industrial and automotive thermal requirements.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. Both parts carry this rating, eliminating moisture-related handling constraints during storage and assembly.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant. The SRF0703-680M carries additional REACH unaffected status. Both are classified under ECCN EAR99 for export purposes.

Q: Can these parts be used interchangeably in parallel and series configurations?

A: Yes. Both parts support dual-configuration operation with identical current ratings in each mode (890 mA parallel, 444 mA series) and identical saturation points (960 mA parallel, 480 mA series).
