• Inductance test frequency: 100 kHz
• Shielding type: Unshielded
• Mounting type: Surface Mount
• Component type: Wirewound inductor
• Saturation current (Isat): 3 A minimum

Secondary Compatibility Parameters:

• Current rating: 3 A or higher
• DC resistance: Within acceptable limits for the application
• Operating temperature range: Minimum -25°C to 85°C coverage

The substitute parts listed below meet these core electrical and mechanical requirements, allowing direct functional replacement in applications where the UP2UC-150-R is specified.

Parameter Comparison

Engineering Selection Recommendations

P0751.153NLT (Pulse Electronics): This substitute maintains the 15 µH inductance specification with ±20% tolerance and 100 kHz test frequency, matching the primary electrical characteristics of the UP2UC-150-R. The 3 A current rating meets the saturation current requirement. The extended operating temperature range (-40°C to 130°C) provides broader thermal coverage. DC resistance of 55 mOhm represents a 9 mOhm increase over the primary part. Physical dimensions are within 0.010" variance on length and 0.024" on width. ROHS3 compliance and MSL 1 rating confirm environmental qualification. This part is suitable for applications where the slightly higher DCR is acceptable and extended temperature operation is beneficial.

SDR1005-150ML (Bourns Inc.): This substitute provides the 15 µH inductance with ±20% tolerance and maintains the 3 A saturation current specification. The drum core, ferrite construction differs from the standard wirewound design of the primary part. The 2.5 A current rating is 0.6 A lower than the UP2UC-150-R, requiring verification that application current demands do not exceed this limit. DC resistance of 60 mOhm represents a 14 mOhm increase. Physical dimensions match the primary part on length and width, with height 0.008" lower. The 1 kHz inductance test frequency differs from the 100 kHz specification of the primary part. Extended operating temperature range (-40°C to 125°C) and ROHS3 compliance are confirmed. This part is suitable for applications with current requirements at or below 2.5 A where the ferrite core construction is acceptable.

Frequently Asked Questions (FAQ)

Q: Can P0751.153NLT directly replace UP2UC-150-R in all applications?

A: P0751.153NLT meets the core electrical specifications: 15 µH inductance, ±20% tolerance, 3 A saturation current, and 100 kHz test frequency. The 55 mOhm DCR is 9 mOhm higher than the 46 mOhm maximum of the primary part. Applications sensitive to DC resistance losses or thermal dissipation must evaluate this 19.6% increase. Physical dimensions are compatible with minor variance. ROHS3 compliance and MSL 1 rating confirm environmental qualification.

Q: What are the limitations of SDR1005-150ML as a substitute?

A: SDR1005-150ML has a 2.5 A current rating, which is 0.6 A lower than the UP2UC-150-R 3.1 A rating. Applications operating at continuous currents above 2.5 A cannot use this substitute. The inductance test frequency is 1 kHz rather than 100 kHz, which may affect measured inductance values in frequency-dependent applications. DC resistance of 60 mOhm is 14 mOhm higher than the primary part. The ferrite drum core construction differs from the standard wirewound design. These factors require application-specific evaluation.

Q: Are all substitute parts RoHS compliant?

A: Yes. The primary part UP2UC-150-R carries RoHS Compliant status. Both substitute parts P0751.153NLT and SDR1005-150ML carry ROHS3 Compliant status, confirming compliance with current RoHS directives. All three parts have MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the physical footprint compatibility?

A: UP2UC-150-R dimensions are 0.500" L x 0.394" W x 0.205" H (12.70 mm x 10.00 mm x 5.21 mm). P0751.153NLT is 0.510" L x 0.370" W x 0.215" H (12.95 mm x 9.40 mm x 5.46 mm), representing +0.010" length, -0.024" width, and +0.010" height variance. SDR1005-150ML is 0.500" L x 0.394" W x 0.197" H (12.70 mm x 10.00 mm x 5.00 mm), matching length and width exactly with -0.008" height variance. PCB layout and clearance requirements must be verified for each substitute.

Q: How do DC resistance differences affect circuit performance?

A: UP2UC-150-R specifies 46 mOhm maximum DCR. P0751.153NLT specifies 55 mOhm (9 mOhm higher), and SDR1005-150ML specifies 60 mOhm (14 mOhm higher). In applications with 3 A current, power dissipation increases from 0.414 W (primary part) to 0.495 W (P0751.153NLT) or 0.540 W (SDR1005-150ML). Thermal management and circuit efficiency calculations must account for these differences.

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

A: UP2UC-150-R and P0751.153NLT use standard wirewound construction. SDR1005-150ML uses drum core, ferrite construction. Drum core inductors typically offer improved high-frequency performance and lower EMI characteristics. The ferrite core material affects frequency response and saturation behavior. Applications requiring specific frequency response or EMI performance must evaluate construction type compatibility.
