Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria (Must Match):

• Inductance value: 47 µH ±20% tolerance
• Mounting type: Surface Mount
• Shielding configuration: Unshielded
• Inductance test frequency: 100 kHz
• RoHS compliance status: ROHS3 Compliant

Secondary Compatibility Parameters (Allowable Variation):

• Current rating: Minimum 1.6 A (substitute must support application current requirements)
• DC resistance: Maximum 168 mOhm (minor variation acceptable within thermal budget)
• Operating temperature: Minimum -40°C to 85°C (application dependent)
• Saturation current: Minimum 1.4 A (application dependent)
• Package dimensions: Nonstandard form factor with surface mount compatibility

All four substitute parts meet the primary substitution criteria. Variations in current rating, DCR, and temperature range reflect manufacturer design differences and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

AX97-30470 (Triad Magnetics): Matches current rating (2.0 A) and maintains DCR specification (160 mOhm). Drum core construction with ferrite material provides alternative core design. Operating temperature limited to 85°C; suitable for applications not requiring extended high-temperature operation. ROHS3 compliant. Bulk packaging requires reel conversion for automated assembly.

P0751.473NLT (Pulse Electronics): Highest inventory availability (2280 pcs). Extended operating temperature range (-40°C to 130°C) exceeds main part specification. Current rating reduced to 1.6 A; suitable for applications with lower current requirements. DCR specification (168 mOhm) represents maximum allowable variation. ROHS3 compliant with MSL 1 rating. Tape & Reel packaging compatible with standard assembly processes.

UP2-470-R (Eaton - Electronics Division): Current rating (1.9 A) closely approaches main part specification. DCR specification (146.1 mOhm) represents lowest resistance option, reducing thermal dissipation. Wirewound construction maintains core design consistency. Operating temperature range not specified; verify application requirements. RoHS compliant (standard designation). Tape & Reel packaging. UNI-PAC™ 2 series designation.

UP2B-470-R (Eaton - Electronics Division): Lowest DCR specification (138.8 mOhm) among substitutes. Drum core construction with ferrite material. Current rating (1.7 A) suitable for moderate current applications. Operating temperature limited to 85°C. ROHS3 compliant with MSL 1 rating. Tape & Reel packaging. UNI-PAC™ series designation.

Frequently Asked Questions (FAQ)

Q: Can I substitute SC3326F-470 with any of these parts in my application?

A: Substitution eligibility depends on your specific application current requirements and operating temperature range. All four substitute parts maintain the 47 µH inductance value and ±20% tolerance. However, current ratings vary: AX97-30470 and main part support 2.0 A; UP2-470-R supports 1.9 A; UP2B-470-R supports 1.7 A; P0751.473NLT supports 1.6 A. Select a substitute with current rating equal to or exceeding your application requirement.

Q: What is the significance of DC Resistance (DCR) variation among these parts?

A: DCR directly affects thermal dissipation and power loss in the inductor. Lower DCR reduces heat generation. SC3326F-470 specifies 150 mOhm maximum; substitutes range from 138.8 mOhm (UP2B-470-R) to 168 mOhm (P0751.473NLT). All values remain within acceptable engineering tolerance for 47 µH inductors. Select based on thermal budget requirements.

Q: Are there packaging differences I should consider?

A: SC3326F-470, P0751.473NLT, UP2-470-R, and UP2B-470-R are supplied in Tape & Reel (TR) format, compatible with standard pick-and-place assembly equipment. AX97-30470 is supplied in Bulk packaging and requires reel conversion or manual handling for automated assembly processes.

Q: What is the operating temperature limitation for each substitute?

A: SC3326F-470 operates -40°C to 125°C. P0751.473NLT extends to 130°C. AX97-30470 and UP2B-470-R are limited to 85°C. UP2-470-R does not specify operating temperature range. Verify your application's thermal environment against the selected substitute's rated range.

Q: Do all substitutes maintain RoHS compliance?

A: Yes. SC3326F-470, AX97-30470, P0751.473NLT, and UP2B-470-R are ROHS3 compliant. UP2-470-R carries standard RoHS compliance designation. All parts are REACH unaffected and classified under ECCN EAR99.

Q: What is the difference between wirewound and drum core construction?

A: SC3326F-470 and P0751.473NLT use wirewound construction. AX97-30470 and UP2B-470-R use drum core wirewound construction with ferrite material. Drum core design typically provides improved EMI characteristics and compact form factors. Both construction types maintain the specified 47 µH inductance and unshielded configuration.

Q: Which substitute offers the best inventory availability?

A: P0751.473NLT (Pulse Electronics) maintains the highest inventory level at 2280 pcs. SC3326F-470 has 840 pcs; UP2-470-R has 1373 pcs; UP2B-470-R has 1232 pcs; AX97-30470 has 852 pcs.
