UP5-100-R Fixed Inductor Equivalent & Substitute Parts

Part Overview

The UP5-100-R is a 10 µH unshielded wirewound surface mount inductor manufactured by Eaton - Electronics Division as part of the UNI-PAC™ 5 series. This component is rated for 4.3 A continuous current with a maximum DC resistance of 31 mOhm and operates across the temperature range of -25°C to 105°C. The part maintains Active product status with RoHS compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when they satisfy the critical electrical and mechanical parameters required for direct replacement in circuit applications. Substitutes must match inductance value, current rating, DC resistance specification, and physical mounting compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP5-100-R is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value: 10 µH (±20% tolerance band)
• Current rating: 4.3 A minimum continuous rating
• Saturation current (Isat): 10 A minimum
• DC resistance: 31 mOhm maximum
• Shielding configuration: Unshielded
• Self-resonant frequency: 20 MHz or higher

Mechanical Equivalence Requirements:

• Mounting type: Surface Mount
• Package classification: Nonstandard
• Physical dimensions: Compatible with 0.724" L × 0.591" W footprint (18.40 mm × 15.00 mm)
• Height seated maximum: 0.295" (7.50 mm) or less

Compliance Requirements:

• RoHS compliance status (RoHS Compliant or ROHS3 Compliant acceptable)
• Moisture sensitivity level: MSL 1 (Unlimited)
• Product status: Active

The substitute part 74458010 (Würth Elektronik WE-PD4 series) meets all electrical and mechanical equivalence criteria and maintains active product status with enhanced compliance certifications.

Engineering Selection Recommendations

Primary Selection: UP5-100-R (Eaton - Electronics Division)

The UP5-100-R remains the primary component choice when original manufacturer specification and UNI-PAC™ 5 series continuity are required. This part is Active status with full RoHS compliance and 737 units available in current inventory.

Substitute Selection: 74458010 (Würth Elektronik WE-PD4 Series)

The 74458010 is a qualified substitute meeting all electrical and mechanical equivalence criteria. This part offers the following advantages:

• Identical electrical performance across all critical parameters (inductance, current rating, DC resistance, saturation current)
• Enhanced operating temperature range (-40°C to 125°C versus -25°C to 105°C)
• ROHS3 compliance certification with REACH Unaffected status
• Larger available inventory (7190 units in stock)
• Drum core ferrite construction with slightly improved self-resonant frequency margin (20 MHz)
• Marginally reduced seated height (0.280" versus 0.295")

Both parts are Active status products with MSL 1 rating and surface mount configuration. Physical dimensions are compatible within standard PCB layout tolerances. Selection between these parts depends on supply chain availability, inventory requirements, and compliance documentation needs.

Frequently Asked Questions (FAQ)

Q: Can the 74458010 directly replace the UP5-100-R in existing circuit designs?

A: Yes. The 74458010 meets all electrical equivalence criteria: 10 µH inductance, 4.3 A current rating, 31 mOhm maximum DC resistance, 10 A saturation current, and unshielded configuration. Physical dimensions are compatible with standard PCB layouts designed for the UP5-100-R footprint.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Eaton versus Würth Elektronik), core material construction (unspecified versus ferrite drum core), operating temperature range (-25°C to 105°C versus -40°C to 125°C), and compliance certifications (RoHS Compliant versus ROHS3 Compliant with REACH status). Electrical performance is identical.

Q: Are the physical dimensions identical?

A: Dimensions are compatible but not identical. The 74458010 is slightly larger in length and width (0.730" × 0.600" versus 0.724" × 0.591") but has reduced seated height (0.280" versus 0.295"). These differences fall within standard PCB layout tolerances for nonstandard package inductors.

Q: What is the significance of the ±20% inductance tolerance?

A: The ±20% tolerance band means the actual inductance value can range from 8 µH to 12 µH. Both the UP5-100-R and 74458010 share this tolerance specification, ensuring equivalent performance variation across production batches.

Q: Does the self-resonant frequency difference (21 MHz versus 20 MHz) affect substitution?

A: No. Both frequencies exceed typical operating requirements for 10 µH inductors in standard applications. The 1 MHz difference is within normal manufacturing variation and does not impact functional equivalence.

Q: What does MSL 1 (Unlimited) mean for handling and storage?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts can be stored at standard ambient conditions without desiccant packaging or time-limited shelf life restrictions.

Q: Are there any application restrictions when using the 74458010 as a substitute?

A: No application restrictions exist based on the provided specifications. The substitute meets or exceeds all electrical and mechanical parameters. Selection should be based on supply availability, compliance documentation requirements, and inventory management priorities.
