Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria applied strictly to the provided parameters:

Primary Criteria (Must Match):

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

Secondary Criteria (Allowable Variation):

• Current rating: Minimum 1.6 A (acceptable if equal to or greater than 80% of main part rating)
• DC resistance: Maximum 168 mOhm (acceptable if within ±12% of main part specification)
• Operating temperature range: Minimum -40°C lower bound; upper bound minimum 85°C
• Type: Wirewound or Drum Core Wirewound (both acceptable)
• RoHS compliance: ROHS3 or equivalent

All four substitute parts meet these criteria and are classified as direct electrical equivalents within the specified tolerance windows.

Parameter Comparison

Engineering Selection Recommendations

AX97-30470 (Triad Magnetics): Maintains 2 A current rating matching the main part. DC resistance of 160 mOhm is within acceptable tolerance. Operating temperature range limited to -40°C ~ 85°C; suitable for applications not requiring the extended upper temperature capability of the main part. ROHS3 compliant. Drum core construction provides alternative core geometry.

P0751.473NL and P0751.473NLT (Pulse Electronics): Both variants share identical electrical specifications with 1.6 A current rating and 168 mOhm DCR. Extended operating temperature range to 130°C exceeds main part capability. P0751.473NLT supplied in Tape & Reel packaging for automated assembly; P0751.473NL supplied in bulk. ROHS3 compliant. Current rating reduction to 1.6 A requires verification that application does not demand the full 2 A capability.

UP2-470-R (Eaton - Electronics Division): Current rating of 1.9 A approaches main part specification. DC resistance of 146.1 mOhm is superior to main part. Operating temperature range not specified in provided data. RoHS compliant. Supplied in Tape & Reel packaging. Wirewound construction.

UP2B-470-R (Eaton - Electronics Division): Current rating of 1.7 A and DC resistance of 138.8 mOhm (lowest among substitutes) provide favorable electrical characteristics. Operating temperature range limited to -40°C ~ 85°C. ROHS3 compliant. Drum core construction. Supplied in Tape & Reel packaging.

Frequently Asked Questions (FAQ)

Q: Can P0751.473NL or P0751.473NLT be used if my application requires the full 2 A current rating?

A: No. These parts are rated for 1.6 A continuous current, which is 20% below the main part specification. Use only if your application current requirement does not exceed 1.6 A.

Q: What is the difference between P0751.473NL and P0751.473NLT?

A: Both parts are electrically identical with 47 µH inductance, 1.6 A rating, and 168 mOhm DCR. The difference is packaging: P0751.473NL is supplied in bulk; P0751.473NLT is supplied in Tape & Reel format for automated pick-and-place assembly.

Q: Does AX97-30470 have a lower operating temperature limit than the main part?

A: Yes. AX97-30470 operates to 85°C maximum, while SC10F-470 operates to 125°C. If your application requires operation above 85°C, AX97-30470 is not suitable.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry RoHS compliance certification (ROHS3 or equivalent), matching the main part's compliance status.

Q: What does "Drum Core" mean in the inductor type?

A: Drum core refers to the physical core geometry used in the wirewound construction. AX97-30470 and UP2B-470-R use drum core geometry, while SC10F-470, P0751.473NL, P0751.473NLT, and UP2-470-R use standard wirewound construction. Both geometries are unshielded and functionally equivalent within the specified electrical parameters.

Q: Which substitute has the lowest DC resistance?

A: UP2B-470-R with 138.8 mOhm maximum DCR, compared to the main part's 150 mOhm. This represents approximately 7.5% lower resistance.

Q: Can I use UP2-470-R or UP2B-470-R if operating temperature is not specified in my design?

A: UP2-470-R has no specified operating temperature range in the provided data. UP2B-470-R is specified to -40°C ~ 85°C. If your application operates within standard industrial temperature ranges (-40°C to +85°C), both are acceptable. For extended temperature operation, verify with the manufacturer or select alternatives with specified ranges.
