SC3316F-470 Equivalent & Substitute Parts

Part Overview

The SC3316F-470 is a 47 µH unshielded wirewound surface mount inductor manufactured by Signal Transformer, rated for 1.8 A continuous current with 160 mOhm maximum DC resistance. This component is designed for applications requiring fixed inductance in compact nonstandard packages and maintains Active product status with full RoHS3 compliance.

Substitute parts become necessary when the original SC3316F-470 experiences supply constraints, extended lead times, or when design requirements permit operation within the electrical and mechanical tolerances of alternative manufacturers' offerings. Equivalent inductors from Pulse Electronics, Triad Magnetics, and Eaton provide compatible electrical characteristics while maintaining the same 47 µH inductance value and ±20% tolerance specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC3316F-470 is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 47 µH (exact match required)
• Inductance tolerance: ±20% (exact match required)
• Shielding configuration: Unshielded (exact match required)
• Mounting type: Surface Mount (exact match required)
• Inductance test frequency: 100 kHz (exact match required)

Secondary Compatibility Parameters:

• Current rating: Minimum 1.8 A (equal or greater acceptable)
• DC resistance: Maximum 160 mOhm (equal or lower acceptable)
• Operating temperature range: Minimum -40°C to 125°C (equal or wider acceptable)
• RoHS3 compliance: Required
• MSL rating: MSL 1 acceptable

All substitute parts listed below meet these criteria and are qualified for direct replacement in applications designed for the SC3316F-470.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and full RoHS3 compliance, ensuring regulatory alignment with the SC3316F-470 across industrial and commercial applications.

AX97-30470 (Triad Magnetics): Offers the highest current rating at 2.0 A with matching 160 mOhm DCR specification. Drum core construction provides alternative core geometry. Operating temperature range limited to -40°C to 85°C; suitable for applications not requiring the full 125°C upper limit of the original part.

P0751.473NL and P0751.473NLT (Pulse Electronics): Both variants provide extended operating temperature to 130°C, exceeding the SC3316F-470 specification. DCR specification of 168 mOhm remains within acceptable tolerance. Current rating of 1.6 A is lower than the original 1.8 A; suitable for applications with reduced current requirements. P0751.473NLT provides Tape & Reel packaging matching the original SC3316F-470 format.

UP2-470-R (Eaton - Electronics Division): Delivers 1.9 A current rating with superior DCR of 146.1 mOhm, reducing resistive losses. UNI-PAC™ 2 series construction. Operating temperature range not specified; verify application requirements before selection.

UP2B-470-R (Eaton - Electronics Division): Provides lowest DCR at 138.8 mOhm with 1.7 A current rating. Drum core, ferrite construction. Operating temperature range limited to -40°C to 85°C. Suitable for applications prioritizing low resistance performance within the specified temperature window.

Frequently Asked Questions (FAQ)

Q: Can P0751.473NL or P0751.473NLT be used in place of SC3316F-470 if my application operates below 1.8 A?

A: Yes. Both Pulse Electronics parts are qualified substitutes when continuous current requirements do not exceed 1.6 A. The 168 mOhm DCR specification remains within acceptable tolerance, and the extended operating temperature range to 130°C provides additional margin. Verify saturation current (Isat) requirements; both parts specify 1.6 A Isat matching the original SC3316F-470.

Q: What is the difference between AX97-30470 and the original SC3316F-470 in terms of core construction?

A: The AX97-30470 uses drum core, ferrite construction, while the SC3316F-470 employs standard wirewound construction. Both are unshielded and maintain identical 47 µH inductance and ±20% tolerance. The drum core design may exhibit different frequency response characteristics; confirm compatibility with application-specific frequency requirements.

Q: Does the operating temperature limitation of AX97-30470 and UP2B-470-R affect substitution eligibility?

A: Operating temperature range is a secondary compatibility parameter. Both parts are qualified substitutes for applications operating within their specified ranges (-40°C to 85°C). Applications requiring the full -40°C to 125°C range of the SC3316F-470 must select P0751.473NL, P0751.473NLT, or UP2-470-R.

Q: Why does UP2-470-R show no specified operating temperature range?

A: The operating temperature range is not provided in the manufacturer data for UP2-470-R. Contact the supplier or manufacturer for complete thermal specifications before selection for temperature-critical applications.

Q: Is Tape & Reel packaging required for substitution?

A: Packaging format is not a substitution criterion. SC3316F-470 is supplied in Tape & Reel format. P0751.473NLT and both Eaton parts (UP2-470-R, UP2B-470-R) also provide Tape & Reel packaging. AX97-30470 and P0751.473NL are supplied in Bulk format; confirm compatibility with assembly processes before selection.

Q: Can I use UP2B-470-R if my design requires saturation current of 1.6 A or higher?

A: No. UP2B-470-R specifies Isat of 1.4 A, which is lower than the SC3316F-470 specification of 1.6 A. Select AX97-30470, P0751.473NL, P0751.473NLT, or UP2-470-R for applications requiring Isat ≥ 1.6 A.

Q: What is the significance of MSL rating "Not Applicable" for AX97-30470?

A: MSL (Moisture Sensitivity Level) classification applies to components sensitive to moisture absorption during storage and handling. AX97-30470 is classified as "Not Applicable," indicating the component does not require moisture-controlled storage. All other substitutes carry MSL 1 (Unlimited), matching the SC3316F-470 specification.
