UP2C-150-R Equivalent & Substitute Parts Reference

Part Overview

The UP2C-150-R is a 15 µH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division, part of the UNI-PAC™ 2C series. This component is rated for 3.17 A continuous current with a DC resistance of 36.9mOhm and operates across the temperature range of -40°C to 85°C. The part is currently obsolete, necessitating identification of equivalent substitute components that maintain functional compatibility in surface mount applications requiring fixed inductance values in the 15 µH range.

Substitute Part Grouping Explanation

Substitution of the UP2C-150-R is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 15 µH (fixed requirement)
• Inductance tolerance: ±20% (fixed requirement)
• Shielding configuration: Unshielded (fixed requirement)
• Core material: Ferrite (fixed requirement)
• Mounting type: Surface Mount (fixed requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (fixed requirement)

Secondary Compatibility Parameters:

• Current rating must equal or exceed 3.17 A
• DC resistance must not exceed 36.9mOhm significantly
• Operating temperature range must encompass or extend the original -40°C to 85°C specification
• Inductance test frequency alignment at 100 kHz preferred

All substitute parts listed maintain the core electrical specification of 15 µH ±20% inductance with unshielded ferrite drum core construction in surface mount packages. Variations in current rating, DC resistance, and temperature range are acceptable provided the application requirements are satisfied.

Engineering Selection Recommendations

B82476B1153M100 (EPCOS - TDK Electronics)

This component is the primary direct substitute. It maintains identical inductance (15 µH ±20%), unshielded ferrite drum core construction, and surface mount configuration. The current rating of 3.4 A exceeds the original 3.17 A specification. DC resistance of 40mOhm Max is marginally higher than the original 36.9mOhm but remains within acceptable tolerance for most applications. The extended operating temperature range (-55°C to 150°C) provides superior thermal coverage. The part is Active status with AEC-Q200 automotive qualification and ROHS3 compliance. Inductance test frequency alignment at 100 kHz matches the original specification.

SDR1005-150ML (Bourns Inc.)

This component provides equivalent inductance and core construction with Active product status and ROHS3 compliance. The current rating of 2.5 A is lower than the original 3.17 A specification and may limit application in higher current circuits. DC resistance of 60mOhm Max is significantly higher than the original 36.9mOhm, resulting in increased power dissipation. Operating temperature range of -40°C to 125°C extends above the original specification. Inductance test frequency of 1 kHz differs from the original 100 kHz specification. This substitute is suitable only for applications with current requirements below 2.5 A and where increased DC resistance is acceptable.

P0751.153NLT (Pulse Electronics)

This component maintains the 15 µH ±20% inductance specification with Active product status and ROHS3 compliance. Current rating of 3 A is slightly below the original 3.17 A but provides near-equivalent performance. DC resistance of 55mOhm Max is higher than the original 36.9mOhm. Operating temperature range of -40°C to 130°C extends above the original specification. Inductance test frequency alignment at 100 kHz matches the original. Core material is not specified in available documentation. This substitute is suitable for applications where the 3 A current rating is sufficient and increased DC resistance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the B82476B1153M100 directly replace the UP2C-150-R without circuit modification?

A: The B82476B1153M100 maintains identical inductance value (15 µH ±20%), unshielded ferrite drum core construction, and surface mount package configuration. The higher current rating (3.4 A vs. 3.17 A) and marginally higher DC resistance (40mOhm Max vs. 36.9mOhm) are compatible with the original specification. Direct substitution is supported without circuit modification for applications operating within the original current and temperature parameters.

Q: Why does the SDR1005-150ML have a lower current rating than the original part?

A: The SDR1005-150ML is rated for 2.5 A continuous current, which is lower than the UP2C-150-R specification of 3.17 A. This reflects different core geometry and wire gauge design choices by Bourns Inc. This substitute is suitable only for applications where the circuit current does not exceed 2.5 A. Applications requiring the full 3.17 A rating should use the B82476B1153M100 or P0751.153NLT instead.

Q: What is the significance of DC resistance differences between substitute parts?

A: DC resistance directly affects power dissipation in the inductor. The original UP2C-150-R has 36.9mOhm DCR. The B82476B1153M100 (40mOhm Max) represents a 3% increase, the P0751.153NLT (55mOhm Max) represents a 49% increase, and the SDR1005-150ML (60mOhm Max) represents a 63% increase. Higher DC resistance results in increased heat generation at equivalent current levels. Applications sensitive to thermal performance should prioritize the B82476B1153M100 substitute.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The B82476B1153M100, SDR1005-150ML, and P0751.153NLT are all ROHS3 compliant. The original UP2C-150-R RoHS status is not specified in available documentation. All active substitute parts meet current environmental compliance requirements.

Q: What is the difference between inductance test frequency specifications?

A: The UP2C-150-R, B82476B1153M100, and P0751.153NLT specify inductance measurement at 100 kHz. The SDR1005-150ML specifies inductance measurement at 1 kHz. Inductance values can vary slightly with frequency due to core material properties. For applications where inductance performance at 100 kHz is critical, the B82476B1153M100 or P0751.153NLT are preferred to ensure specification alignment.

Q: Can the P0751.153NLT be used in applications requiring the full 3.17 A rating?

A: The P0751.153NLT is rated for 3 A continuous current, which is 0.17 A below the original 3.17 A specification. For applications operating consistently at or above 3.17 A, the B82476B1153M100 (3.4 A rating) is the recommended substitute. The P0751.153NLT is suitable for applications where peak current does not exceed 3 A or where average current is significantly below this threshold.

Q: How do operating temperature ranges affect part selection?

A: The original UP2C-150-R operates from -40°C to 85°C. All substitute parts extend this range: B82476B1153M100 (-55°C to 150°C), SDR1005-150ML (-40°C to 125°C), and P0751.153NLT (-40°C to 130°C). For applications operating within the original -40°C to 85°C window, all substitutes are compatible. For applications requiring extended temperature operation, all substitutes provide superior thermal coverage.
