UP5S-150-R Equivalent & Substitute Parts

Part Overview

The UP5S-150-R is a 15 µH shielded wirewound surface mount inductor manufactured by Eaton - Electronics Division, part of the UNI-PAC™ 5S series. This component is rated for 3.6 A continuous current with a maximum DC resistance of 35 mOhm and operates across the temperature range of -25°C to 85°C. The part is ROHS3 compliant and carries an MSL rating of 1 (Unlimited). The UP5S-150-R is currently in active production status with 1087 units available in stock.

Substitute parts are identified when equivalent inductance values, current ratings, and electrical characteristics fall within acceptable tolerance ranges for the application, while maintaining surface mount compatibility and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UP5S-150-R are identified based on the following critical electrical and mechanical parameters:

Primary Matching Criteria:

• Inductance value of 15 µH at 100 kHz test frequency
• Surface mount nonstandard package configuration
• Wirewound construction type
• Current rating capability of 3.6 A or greater
• DC resistance within acceptable operating limits
• ROHS3 compliance and MSL 1 rating

Substitution Logic: The P0250.153NLT from Pulse Electronics meets the core electrical requirements with matching 15 µH inductance and exceeds the current rating specification at 4 A. The saturation current of 8 A provides additional margin. The DC resistance of 36 mOhm is within 1 mOhm of the maximum specification. Physical dimensions are comparable within nonstandard package tolerances. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity ratings.

The primary distinction is shielding configuration: the UP5S-150-R is shielded while the P0250.153NLT is unshielded. This difference must be evaluated against specific application electromagnetic interference requirements.

Engineering Selection Recommendations

UP5S-150-R Selection Criteria: The UP5S-150-R remains the primary choice when shielded inductor performance is required to minimize electromagnetic interference in sensitive circuit environments. The shielded design provides controlled magnetic field containment. This part is actively produced and maintains full ROHS3 compliance with unlimited moisture sensitivity rating suitable for standard manufacturing and storage conditions.

P0250.153NLT Selection Criteria: The P0250.153NLT from Pulse Electronics serves as an electrical equivalent when shielding is not a circuit requirement. This unshielded alternative provides superior current rating margin (4 A versus 3.6 A) and saturation current (8 A versus 6.4 A), making it suitable for applications with higher transient current demands. The wider operating temperature range (-40°C to 130°C) accommodates extended environmental specifications. The tighter inductance tolerance (±15% versus ±20%) may benefit precision-dependent applications. Both parts maintain identical ROHS3 compliance and MSL 1 ratings.

Substitution Feasibility: Direct substitution is electrically valid when electromagnetic shielding is not specified as a functional requirement. Physical footprint compatibility is confirmed through comparable nonstandard package dimensions. Both parts are actively produced with established supply availability.

Frequently Asked Questions (FAQ)

Q: Can the P0250.153NLT replace the UP5S-150-R in all applications?

A: Electrical substitution is valid when the circuit does not require shielded inductor performance. The unshielded P0250.153NLT will function correctly in applications where magnetic field containment is not specified. Applications sensitive to electromagnetic interference or requiring controlled magnetic coupling must retain the shielded UP5S-150-R.

Q: What is the significance of the 1 mOhm difference in DC resistance?

A: The P0250.153NLT maximum DC resistance of 36 mOhm is 1 mOhm higher than the UP5S-150-R specification of 35 mOhm maximum. This difference results in marginally increased resistive losses. For most applications, this variation is negligible. Thermal-sensitive designs should calculate power dissipation impact using actual measured DCR values from component datasheets.

Q: Are the physical dimensions compatible for PCB layout?

A: Both parts use nonstandard surface mount packages with comparable dimensions. The UP5S-150-R measures 18.40 mm × 15.00 mm × 7.50 mm (height), while the P0250.153NLT measures 18.62 mm × 15.14 mm × 7.36 mm. These variations are within typical PCB layout tolerances. Verify footprint compatibility with your specific PCB design before implementation.

Q: What is the difference between shielded and unshielded inductors?

A: Shielded inductors (UP5S-150-R) contain the magnetic field within a protective enclosure, reducing electromagnetic interference with adjacent circuit components. Unshielded inductors (P0250.153NLT) allow the magnetic field to radiate freely, which may cause coupling with nearby traces or components. Shielding adds cost and size but provides EMI containment. Selection depends on circuit layout density and interference sensitivity.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the UP5S-150-R and P0250.153NLT are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. Both carry EAR99 export classification. Compliance certifications are equivalent for standard manufacturing and assembly environments.

Q: Which part has better current handling capability?

A: The P0250.153NLT provides superior current margin with a 4 A continuous rating and 8 A saturation current, compared to the UP5S-150-R at 3.6 A continuous and 6.4 A saturation. The P0250.153NLT is suitable for applications requiring higher current capacity or greater transient current tolerance.

Q: What is the operating temperature difference between these parts?

A: The UP5S-150-R operates from -25°C to 85°C, while the P0250.153NLT operates from -40°C to 130°C. The P0250.153NLT accommodates extended low-temperature and high-temperature environments. Selection depends on application thermal requirements.
