Engineering Selection Recommendations

P0752.334NLT (Pulse Electronics) - Primary Substitute

The P0752.334NLT provides direct electrical equivalence to the UP2UC-331-R with identical inductance (330 µH), current rating (600 mA), and DC resistance (1.02 Ohm Max). Both components are wirewound inductors with ±20% tolerance and MSL 1 rating. The Pulse Electronics part offers an extended operating temperature range (-40°C to 130°C) compared to the Eaton original (-25°C to 85°C). Physical dimensions are within nonstandard package classification with minimal height variation (5.46mm vs 5.21mm). Both parts maintain ROHS3 compliance and active product status. Inventory availability is significantly higher for the substitute (6300 pcs vs 888 pcs).

SDR1005-331KL (Bourns Inc.) - Secondary Substitute

The SDR1005-331KL maintains the 330 µH inductance specification with improved tolerance (±10% vs ±20%). However, this part presents the following parameter deviations: continuous current rating of 550 mA (versus 600 mA requirement), DC resistance of 1.15 Ohm Max (versus 1.02 Ohm Max), and drum core ferrite construction (versus standard wirewound). The saturation current (Isat) remains at 600 mA. Physical dimensions match the original part length and width (12.70mm x 10.00mm) with lower seated height (5.00mm). Operating temperature range extends to -40°C to 125°C. This part is suitable only when the 550 mA continuous current rating and 1.15 Ohm resistance are acceptable within circuit design margins.

Frequently Asked Questions (FAQ)

Q: Can P0752.334NLT directly replace UP2UC-331-R in all applications?

A: Yes, for applications operating within the -25°C to 85°C temperature range. The P0752.334NLT provides identical electrical specifications (330 µH, 600 mA, 1.02 Ohm) and maintains equivalent mechanical compatibility. The extended temperature capability of the Pulse Electronics part (-40°C to 130°C) provides additional operational margin without affecting performance in the original temperature window.

Q: What are the limitations of SDR1005-331KL as a substitute?

A: The SDR1005-331KL has two parameter deviations: reduced continuous current rating (550 mA vs 600 mA) and increased DC resistance (1.15 Ohm vs 1.02 Ohm). These differences must be evaluated against circuit requirements. The part is suitable only when circuit design can accommodate the lower current rating and higher resistance without exceeding thermal or voltage drop specifications.

Q: Are there physical mounting differences between these parts?

A: All three parts are surface mount components in nonstandard packages. The P0752.334NLT has slightly larger dimensions (12.95mm x 9.40mm vs 12.70mm x 10.00mm) and greater seated height (5.46mm vs 5.21mm). The SDR1005-331KL matches the original footprint (12.70mm x 10.00mm) with lower profile (5.00mm). PCB layout verification is recommended when switching between parts.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. The UP2UC-331-R is RoHS Compliant. Both substitute parts (P0752.334NLT and SDR1005-331KL) are ROHS3 Compliant, meeting current regulatory requirements. All three parts have MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference in inductance tolerance between these parts?

A: The UP2UC-331-R and P0752.334NLT both specify ±20% tolerance. The SDR1005-331KL provides tighter tolerance at ±10%, which may be beneficial for applications requiring more precise inductance values. However, all three parts meet the 330 µH specification within their respective tolerance bands.

Q: Which substitute offers better inventory availability?

A: The P0752.334NLT (Pulse Electronics) has the highest inventory level at 6300 pcs, compared to 888 pcs for the original UP2UC-331-R and 1470 pcs for the SDR1005-331KL. This availability advantage may support supply chain continuity for high-volume applications.
