SC1608F-470 Equivalent & Substitute Parts

Part Overview

The SC1608F-470 is a 47 µH unshielded wirewound inductor manufactured by Signal Transformer, designed for surface mount applications. This component is rated for 560 mA continuous current with a maximum DC resistance of 750 mOhm and operates across the temperature range of -40°C to 125°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

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

Substitute Part Grouping Explanation

Substitution eligibility for the SC1608F-470 is determined by the following critical parameters:

• Inductance Value: Must be 47 µH with ±20% tolerance
• Current Rating: Minimum 530 mA acceptable (within 95% of original 560 mA specification)
• DC Resistance: Maximum 820 mOhm (within acceptable loss parameters for this category)
• Saturation Current: Minimum 500 mA required
• Package Dimensions: Identical footprint (6.60 × 4.45 × 2.92 mm) for mechanical compatibility
• Mounting Type: Surface mount configuration required
• Shielding Configuration: Unshielded topology maintained
• Temperature Range: Minimum -40°C to 85°C acceptable (subset of original range)
• RoHS Compliance: Active compliance status required

The substitute part UP0.4C-470-R meets all substitution criteria within these electrical and mechanical boundaries.

Engineering Selection Recommendations

The UP0.4C-470-R from Eaton Electronics Division qualifies as a direct substitute for the SC1608F-470 based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical inductance values (47 µH) with matching ±20% tolerance specifications. The substitute's current rating of 530 mA remains within acceptable operational margins relative to the original 560 mA specification. DC resistance differential (820 mOhm vs. 750 mOhm) represents a 9.3% increase, which falls within acceptable loss parameters for this inductor category.

Mechanical Compatibility: Identical package footprint (6.60 × 4.45 × 2.92 mm) ensures direct PCB placement compatibility without layout modifications.

Compliance Status: Both parts maintain Active product status with current RoHS compliance certifications. The substitute carries RoHS compliance while the original specifies RoHS3 compliance; both certifications are acceptable for equivalent component selection.

Temperature Operating Range: The substitute's operating range (-40°C to 85°C) represents a subset of the original specification (-40°C to 125°C). Applications requiring operation above 85°C must retain the original SC1608F-470.

Packaging: The substitute is supplied in Tape & Reel format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can UP0.4C-470-R replace SC1608F-470 in all applications?

A: The UP0.4C-470-R is electrically and mechanically compatible for applications operating within -40°C to 85°C. Applications requiring operation above 85°C must use the original SC1608F-470 to maintain the extended temperature specification.

Q: What is the significance of the 30 mA current rating difference?

A: The substitute's 530 mA rating versus the original 560 mA represents a 5.4% reduction. This differential remains within acceptable operational margins for inductor selection in this category. Circuit designs operating near the 560 mA maximum should be evaluated for thermal margin impact.

Q: Does the 70 mOhm increase in DC resistance affect circuit performance?

A: The DC resistance increase from 750 mOhm to 820 mOhm represents a 9.3% differential. This results in proportionally increased resistive losses. Applications with strict power dissipation requirements should calculate the impact: additional loss = (820 - 750) mOhm × (current in amps)² watts.

Q: Are the package dimensions identical?

A: Yes. Both components share identical surface mount footprint dimensions of 6.60 × 4.45 × 2.92 mm (L × W × H), enabling direct PCB placement without layout modifications.

Q: What is the difference between RoHS and RoHS3 compliance?

A: Both certifications indicate compliance with hazardous substance restrictions. RoHS3 represents the current regulatory iteration. Both statuses are acceptable for equivalent component selection in this application category.

Q: Is the Tape & Reel packaging compatible with my assembly process?

A: Tape & Reel packaging is standard for automated surface mount assembly. Manual assembly processes may require component extraction from the reel. Verify your assembly equipment specifications for compatibility.
