UP5S-101-R Equivalent & Substitute Parts

Part Overview

The UP5S-101-R is a 100 µH shielded wirewound inductor manufactured by Eaton - Electronics Division, rated for 1.7 A continuous current with a maximum DC resistance of 180mOhm. This component is part of the UNI-PAC™ 5S series and is classified as Active product status. The part is packaged in Tape & Reel (TR) format for automated assembly processes.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances. Alternative sources may be required due to inventory availability, lead time considerations, or supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UP5S-101-R are identified based on the following electrical and mechanical criteria:

Electrical Equivalence Requirements:

• Inductance value of 100 µH at 100 kHz test frequency
• Current rating of 1.7 A or higher
• DC resistance not exceeding 180mOhm
• Saturation current of 2.46 A or higher
• Operating temperature range that encompasses or exceeds -25°C to 85°C

Mechanical Compatibility Requirements:

• Surface mount package type
• Physical dimensions compatible with 18.40 × 15.00 mm footprint tolerance
• Height within acceptable PCB clearance limits

Regulatory and Compliance Requirements:

• ROHS3 compliance
• Moisture Sensitivity Level 1 classification

The substitute part P0250.104NLT from Pulse Electronics meets the electrical performance criteria with equivalent inductance and superior current ratings. However, this substitute differs in shielding configuration (unshielded versus shielded), which represents a functional trade-off that must be evaluated for specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Shielding Configuration

The UP5S-101-R features shielded construction, while the substitute P0250.104NLT is unshielded. This represents the primary functional difference between the two parts. Shielded inductors contain electromagnetic fields within the component package, reducing radiated EMI and susceptibility to external magnetic field interference. Unshielded inductors have no such containment.

Selection between these parts depends on circuit-level EMI requirements:

• If the application requires EMI containment or operates in electromagnetically noisy environments, the shielded UP5S-101-R is the appropriate choice.
• If EMI shielding is not a circuit requirement, the P0250.104NLT substitute provides equivalent electrical performance with superior current and temperature ratings.

Secondary Considerations:

The P0250.104NLT demonstrates superior electrical performance in current rating (1.8 A vs. 1.7 A), saturation current (3.0 A vs. 2.46 A), inductance tolerance (±15% vs. ±20%), and operating temperature range (-40°C to 130°C vs. -25°C to 85°C). DC resistance remains within acceptable limits at 190mOhm maximum.

Both parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 classification, meeting regulatory requirements for lead-free and moisture-resistant applications.

Packaging Format Difference:

The UP5S-101-R is supplied in Tape & Reel (TR) format, while P0250.104NLT is available in Cut Tape (CT) and Digi-Reel® formats. This difference affects procurement and assembly logistics but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can P0250.104NLT be used as a direct replacement for UP5S-101-R?

A: Electrical substitution is possible if EMI shielding is not required by the circuit design. The P0250.104NLT meets or exceeds all electrical parameters. However, the unshielded construction represents a functional difference that must be evaluated against circuit EMI requirements.

Q: What is the impact of the shielding difference?

A: Shielded inductors (UP5S-101-R) contain magnetic fields within the component, reducing radiated EMI and external field susceptibility. Unshielded inductors (P0250.104NLT) allow magnetic field radiation. In circuits sensitive to EMI or operating in electromagnetically noisy environments, this difference is significant.

Q: Are the physical dimensions compatible?

A: Yes. The P0250.104NLT dimensions (18.62 × 15.14 × 7.36 mm) are compatible with the UP5S-101-R footprint (18.40 × 15.00 × 7.50 mm). Dimensional tolerances are within acceptable PCB assembly limits.

Q: Does the DC resistance difference affect performance?

A: The P0250.104NLT has a maximum DC resistance of 190mOhm compared to 180mOhm for the UP5S-101-R. This 10mOhm difference results in marginally higher power dissipation but remains within acceptable limits for most applications operating at or below 1.7 A.

Q: What are the packaging format implications?

A: UP5S-101-R is supplied in Tape & Reel (TR) format for high-volume automated assembly. P0250.104NLT is available in Cut Tape (CT) and Digi-Reel® formats. Format selection affects procurement quantity minimums and assembly line compatibility but does not impact electrical performance.

Q: Are both parts currently available?

A: Both parts maintain Active product status. UP5S-101-R has 757 pieces in stock; P0250.104NLT has 3350 pieces in stock. Availability should be confirmed with suppliers for specific lead time requirements.

Q: Which part should be selected for new designs?

A: For new designs, the selection depends on EMI requirements. If shielding is not specified, the P0250.104NLT offers superior electrical performance and wider operating temperature range. If shielding is required, the UP5S-101-R is the appropriate choice.
