UP2SC-150-R Equivalent & Substitute Parts

Part Overview

The UP2SC-150-R is a 15 µH shielded wirewound inductor manufactured by Eaton - Electronics Division, rated for 1.7 A continuous current with a maximum DC resistance of 85 mOhm. This component is part of the UNI-PAC™ 2SC series and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for design continuity, procurement planning, and system reliability in applications requiring 15 µH inductance at moderate current levels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP2SC-150-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 15 µH (exact match required)
• Mounting type: Surface Mount (SMD)
• Shielding: Shielded construction
• Core type: Wirewound (acceptable with drum core variant)

Secondary Compatibility Factors:

• Current rating must equal or exceed 1.7 A
• DC resistance must not exceed 85 mOhm
• Operating temperature range must encompass the application requirements
• Saturation current (Isat) must support the circuit's maximum current transients

The DR1040-150-R qualifies as a substitute because it maintains the 15 µH inductance specification, surface mount configuration, and shielded construction. The substitute exhibits improved electrical performance (higher current rating, lower DCR) and extended temperature range, making it suitable for direct replacement in applications previously designed for the UP2SC-150-R.

Engineering Selection Recommendations

Primary Substitute: DR1040-150-R

The DR1040-150-R is the recommended substitute for the obsolete UP2SC-150-R based on the following engineering factors:

1. Electrical Equivalence: Both components maintain 15 µH inductance at 100 kHz test frequency. The DR1040-150-R provides superior electrical performance with 50 mOhm maximum DCR compared to 85 mOhm, resulting in lower power dissipation and improved efficiency.

2. Current Capacity: The DR1040-150-R supports 3.1 A continuous current and 3.6 A saturation current, exceeding the UP2SC-150-R specifications (1.7 A / 2.9 A). This provides design margin for transient conditions and thermal stress.

3. Product Status: The DR1040-150-R is active in production with 2182 pieces in stock, ensuring long-term availability and supply chain stability compared to the obsolete UP2SC-150-R.

4. Compliance & Certifications: The DR1040-150-R is RoHS3 compliant and REACH unaffected, meeting modern regulatory requirements. Both components share identical MSL rating (1 - Unlimited) and ECCN/HTSUS classifications.

5. Temperature Range: The extended operating range (-40°C to 125°C) of the DR1040-150-R accommodates broader environmental conditions than the UP2SC-150-R (-25°C to 85°C).

6. Physical Considerations: The DR1040-150-R is slightly smaller in footprint (10.50mm x 10.30mm vs. 12.70mm x 10.00mm) and lower in height (4.00mm vs. 5.20mm), offering potential PCB layout advantages.

Tolerance Consideration: The DR1040-150-R inductance tolerance is ±30% compared to ±20% for the UP2SC-150-R. Applications requiring tighter inductance tolerance must account for this specification difference during circuit validation.

Frequently Asked Questions (FAQ)

Q1: Can the DR1040-150-R directly replace the UP2SC-150-R without circuit modification?

A: Yes, for applications operating within the UP2SC-150-R specifications. The DR1040-150-R maintains the same 15 µH inductance value, surface mount configuration, and shielded construction. However, verify that the ±30% inductance tolerance of the DR1040-150-R is acceptable for your circuit design, as it is wider than the UP2SC-150-R tolerance of ±20%.

Q2: What are the physical compatibility considerations?

A: The DR1040-150-R has a smaller footprint (10.50mm x 10.30mm) and lower height (4.00mm) compared to the UP2SC-150-R (12.70mm x 10.00mm, 5.20mm height). Verify PCB layout and clearance requirements before substitution. Both components use nonstandard packages, so mechanical fit must be confirmed with the specific PCB design.

Q3: Are there electrical performance differences between these inductors?

A: Yes. The DR1040-150-R exhibits lower DC resistance (50 mOhm max vs. 85 mOhm max), resulting in reduced power loss and heat generation. The higher current rating (3.1 A vs. 1.7 A) and saturation current (3.6 A vs. 2.9 A) provide additional design margin. These improvements make the DR1040-150-R suitable for applications with higher current demands or stricter efficiency requirements.

Q4: What is the significance of the drum core construction in the DR1040-150-R?

A: The DR1040-150-R uses drum core wirewound construction with ferrite core material, compared to the standard wirewound construction of the UP2SC-150-R. Both maintain shielded construction and equivalent inductance. The drum core design contributes to the improved electrical performance and compact dimensions of the substitute part.

Q5: Does the extended temperature range of the DR1040-150-R affect substitution decisions?

A: The DR1040-150-R operating range (-40°C to 125°C) exceeds the UP2SC-150-R range (-25°C to 85°C). This provides additional thermal margin for applications operating at temperature extremes. If your application operates within the UP2SC-150-R temperature range, the extended range of the substitute offers no disadvantage.

Q6: Are there supply chain advantages to using the DR1040-150-R?

A: Yes. The DR1040-150-R is an active product with 2182 pieces currently in stock, compared to the obsolete UP2SC-150-R with limited remaining inventory (755 pieces). For new designs or long-term production, the DR1040-150-R ensures sustained availability and reduces obsolescence risk.

Q7: How do the RoHS and REACH compliance statuses compare?

A: The DR1040-150-R is RoHS3 compliant and REACH unaffected, meeting current environmental regulations. Both components share the same ECCN (EAR99) and HTSUS (8504.50.4000) classifications. For applications requiring modern compliance documentation, the DR1040-150-R provides current certification status.
