Equivalent & Substitute Parts for UP2-470-R

Part Overview

The UP2-470-R is a 47 µH unshielded wirewound surface mount inductor manufactured by Eaton - Electronics Division, part of the UNI-PAC™ 2 series. This component is rated for 1.9 A continuous current with a maximum DC resistance of 146.1 mOhm and operates at 100 kHz test frequency. The part is currently active and available in tape and reel packaging with RoHS compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the original UP2-470-R becomes unavailable, when alternative packaging formats are required, or when application parameters permit operation with higher current ratings or lower DC resistance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP2-470-R is determined by the following parameters:

Primary Matching Criteria:

• Inductance value: 47 µH (exact match required)
• Tolerance: ±20% (all candidates match)
• Mounting type: Surface Mount (all candidates match)
• Test frequency: 100 kHz or compatible frequency

Secondary Compatibility Parameters:

• Current rating: Substitute must equal or exceed 1.9 A
• DC resistance: Lower values are acceptable; higher values require application verification
• Shielding: Unshielded preferred; shielded substitutes acceptable if EMI isolation is not detrimental
• Type: Wirewound or drum core wirewound acceptable
• RoHS/REACH compliance: Active or compliant status required

Packaging Consideration:

• Original part supplied in tape and reel format; bulk and cut tape alternatives available

All three substitute parts meet the primary matching criteria of 47 µH inductance, ±20% tolerance, surface mount configuration, and 100 kHz test frequency compatibility.

Engineering Selection Recommendations

AX97-30470 (Triad Magnetics)

This substitute provides a current rating of 2.0 A, exceeding the UP2-470-R requirement of 1.9 A. DC resistance is 160 mOhm, slightly higher than the original 146.1 mOhm. The part features a ferrite drum core construction with unshielded configuration matching the original shielding characteristic. Operating temperature range is -40°C to 85°C. Product status is active with ROHS3 compliance. Packaging is supplied in bulk format rather than tape and reel. Physical dimensions are comparable to the original part.

P0751.473NLT (Pulse Electronics)

This substitute is supplied in tape and reel packaging, matching the original format. Current rating is 1.6 A, which is lower than the UP2-470-R specification of 1.9 A and requires verification for applications demanding the full 1.9 A rating. DC resistance is 168 mOhm, higher than the original. The part features wirewound construction with unshielded configuration. Operating temperature range extends to -40°C to 130°C, providing broader thermal coverage. Product status is active with ROHS3 compliance and unlimited MSL rating. Saturation current is specified at 1.6 A.

SLF12555T-470M1R6-PF (TDK Corporation)

This substitute offers the highest current rating at 2.5 A and the lowest DC resistance at 74.2 mOhm, providing superior electrical performance. The part features shielded construction with ferrite drum core, differing from the unshielded original. Operating temperature range is -40°C to 105°C. Product status is obsolete, indicating discontinued manufacturing and potential future unavailability. Test frequency is specified at 1 kHz rather than 100 kHz. Packaging is supplied in cut tape format. ROHS3 compliance and unlimited MSL rating are provided.

Frequently Asked Questions (FAQ)

Q: Can P0751.473NLT substitute for UP2-470-R if the application requires 1.9 A continuous current?

A: No. The P0751.473NLT is rated for 1.6 A continuous current, which is below the 1.9 A requirement of the UP2-470-R. This part is suitable only for applications operating at or below 1.6 A.

Q: What is the impact of using AX97-30470 with its 160 mOhm DC resistance instead of the original 146.1 mOhm?

A: The 13.9 mOhm increase in DC resistance results in proportionally higher power dissipation in the inductor. For a 1.9 A application, this represents approximately 9.5% additional resistive loss compared to the original part. Thermal performance and circuit efficiency must be evaluated for the specific application.

Q: Is SLF12555T-470M1R6-PF suitable as a long-term replacement given its obsolete status?

A: The SLF12555T-470M1R6-PF is not recommended for new designs or long-term production use due to its obsolete product status. While it offers superior electrical performance with 2.5 A rating and 74.2 mOhm resistance, discontinued manufacturing status creates supply chain risk. AX97-30470 or P0751.473NLT are preferred for ongoing applications.

Q: How does the shielded construction of SLF12555T-470M1R6-PF affect compatibility with UP2-470-R?

A: The shielded construction of the TDK part reduces electromagnetic field radiation compared to the unshielded original. In applications where EMI isolation is beneficial, the shielded design is advantageous. In circuits where unshielded operation is required or where the shielded design creates unintended coupling effects, compatibility must be verified through circuit analysis.

Q: What packaging format differences exist among the substitute parts?

A: UP2-470-R is supplied in tape and reel format. AX97-30470 is supplied in bulk packaging, requiring manual handling and tape application. P0751.473NLT maintains tape and reel format compatibility with the original. SLF12555T-470M1R6-PF is supplied in cut tape format, requiring individual component handling. Packaging selection depends on assembly process requirements and volume considerations.

Q: Are all substitute parts RoHS compliant?

A: Yes. UP2-470-R is RoHS Compliant. AX97-30470, P0751.473NLT, and SLF12555T-470M1R6-PF are all ROHS3 Compliant, meeting current RoHS requirements.

Q: What is the significance of the different test frequencies (100 kHz vs. 1 kHz)?

A: UP2-470-R, AX97-30470, and P0751.473NLT are characterized at 100 kHz test frequency. SLF12555T-470M1R6-PF is characterized at 1 kHz. Inductance values are frequency-dependent; characterization at different frequencies may result in slight variations in measured inductance at operating frequencies. For applications operating at 100 kHz, parts characterized at 100 kHz provide more accurate performance prediction.
