UP2B-1R5-R Equivalent & Substitute Parts

Part Overview

The UP2B-1R5-R is a 1.5 µH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division. This surface mount component is rated for 8.3 A continuous current with a maximum DC resistance of 8.1 mOhm and operates across the temperature range of -40°C to 85°C. The part is classified as Active product status and is RoHS Compliant with MSL 1 (Unlimited moisture sensitivity level).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this inductor category. Substitution becomes necessary due to inventory availability, supply chain optimization, or design flexibility requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP2B-1R5-R is determined by strict adherence to the following electrical and mechanical criteria:

Primary Matching Criteria:

• Inductance value must be 1.5 µH with ±20% tolerance
• Mounting type must be Surface Mount (SMD)
• Shielding configuration must be Unshielded
• Inductance test frequency must be 100 kHz

Performance Criteria:

• Current rating must be sufficient to handle the application's maximum current demand
• DC resistance must be compatible with thermal and efficiency requirements
• Operating temperature range must encompass the application's operating environment

Compliance Criteria:

• RoHS compliance status must be maintained or upgraded
• Moisture sensitivity level must be MSL 1 or lower
• ECCN and HTSUS classifications must align with regulatory requirements

The substitute part P0751.152NL from Pulse Electronics meets these criteria through matching inductance value, tolerance, surface mount configuration, unshielded design, and test frequency. Variations in current rating, DC resistance, and operating temperature range are evaluated within acceptable engineering parameters for this component category.

Engineering Selection Recommendations

UP2B-1R5-R Selection Criteria:

Select the UP2B-1R5-R when the application requires the higher continuous current rating of 8.3 A and lower DC resistance of 8.1 mOhm maximum. This part is suitable for designs operating within the -40°C to 85°C temperature range. The part maintains Active product status with established supply chain availability (807 Pcs in stock). RoHS Compliance and MSL 1 rating support standard manufacturing and storage protocols.

P0751.152NL Selection Criteria:

Select the P0751.152NL when the application's continuous current requirement is 6.4 A or lower and thermal dissipation from higher DC resistance (12 mOhm maximum) is acceptable. This part is advantageous for applications requiring extended operating temperature coverage up to 130°C. The smaller physical footprint (0.510" L x 0.370" W, 0.215" height) accommodates space-constrained PCB layouts. ROHS3 Compliance and MSL 1 rating provide regulatory alignment with updated standards. The part maintains Active product status with higher inventory availability (3820 Pcs in stock).

Substitution Feasibility:

Direct substitution of P0751.152NL for UP2B-1R5-R is permissible when:

• Application current demand does not exceed 6.4 A continuous
• Increased DC resistance and associated power loss are within design tolerance
• PCB layout accommodates the smaller physical dimensions
• Operating temperature does not exceed 130°C

Direct substitution of UP2B-1R5-R for P0751.152NL is permissible when:

• Higher current rating and lower resistance provide design margin
• Physical dimensions fit within available PCB space
• Operating temperature remains within -40°C to 85°C range

Frequently Asked Questions (FAQ)

Q: Can P0751.152NL replace UP2B-1R5-R in all applications?

A: No. The P0751.152NL has a lower continuous current rating (6.4 A versus 8.3 A) and higher DC resistance (12 mOhm versus 8.1 mOhm). Substitution is valid only when the application's maximum continuous current does not exceed 6.4 A and the increased power dissipation is acceptable.

Q: What is the impact of the higher DC resistance in the P0751.152NL?

A: Higher DC resistance increases power dissipation according to P = I²R. At 6.4 A, the P0751.152NL dissipates approximately 0.49 W compared to 0.42 W for the UP2B-1R5-R at the same current. This difference must be evaluated within the thermal design of the application.

Q: Are the physical dimensions compatible between these parts?

A: No. The P0751.152NL (0.510" L x 0.370" W x 0.215" H) is smaller than the UP2B-1R5-R (0.550" L x 0.410" W x 0.236" H). PCB layout and component placement must be verified before substitution. The smaller Pulse part may fit in space-constrained designs where the Eaton part does not.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are RoHS Compliant and carry MSL 1 (Unlimited) ratings. The P0751.152NL additionally meets ROHS3 Compliance and includes REACH Unaffected status. Both share identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications.

Q: What is the temperature operating range difference?

A: The UP2B-1R5-R operates from -40°C to 85°C. The P0751.152NL extends the upper limit to 130°C. For applications requiring operation above 85°C, the P0751.152NL is the only suitable option between these two parts.

Q: How do the saturation current ratings compare?

A: The UP2B-1R5-R has Isat of 7.9 A while the P0751.152NL has Isat of 8.0 A. These values are comparable and indicate similar core saturation behavior at elevated currents.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For designs requiring 8.3 A continuous current and lower resistance, specify UP2B-1R5-R. For designs with 6.4 A or lower current demand, extended temperature range to 130°C, or space-constrained layouts, specify P0751.152NL. Both parts maintain Active product status and adequate inventory levels.
