UP5S-331-R Equivalent & Substitute Parts

Part Overview

The UP5S-331-R is a 330 µH shielded wirewound surface mount inductor manufactured by Eaton - Electronics Division. Rated for 900 mA continuous current with a maximum DC resistance of 500mOhm, this component is designed for applications requiring electromagnetic shielding and compact form factor. The part is Active status and ROHS3 compliant, suitable for industrial and commercial electronic assemblies. Substitute parts may be required due to inventory constraints, lead time considerations, or application-specific performance requirements within acceptable electrical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP5S-331-R is determined by the following critical parameters:

Mandatory Matching Criteria:

• Inductance value: 330 µH (tolerance range acceptable within ±20%)
• Mounting type: Surface Mount
• Package classification: Nonstandard form factor
• Inductance test frequency: 100 kHz

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 900 mA continuous rating
• Saturation current: Substitute must equal or exceed 1.3 A
• DC resistance: Substitute maximum DCR must not exceed 500mOhm
• Operating temperature: Substitute range must encompass or exceed -25°C to 85°C
• RoHS compliance: ROHS3 Compliant status required

Non-Critical Parameters (May Vary):

• Shielding configuration (shielded or unshielded acceptable based on EMI requirements)
• Inductance tolerance (±15% to ±20% acceptable)
• Physical dimensions (minor variations acceptable if mounting compatibility maintained)

The P0250.334NLT from Pulse Electronics qualifies as a substitute based on matching inductance, mounting type, package classification, and exceeding minimum current and saturation ratings while maintaining DCR within specification.

Engineering Selection Recommendations

UP5S-331-R (Eaton - Electronics Division):

• Primary selection for applications requiring shielded inductor configuration
• Active product status with established supply chain
• ROHS3 compliant and MSL 1 rated
• Operating temperature range -25°C to 85°C suitable for standard industrial applications
• 650 pieces available in current inventory

P0250.334NLT (Pulse Electronics):

• Acceptable substitute where shielding is not a critical requirement
• Unshielded configuration reduces EMI containment but provides cost and space optimization
• Superior current rating (1 A vs. 900 mA) and saturation current (1.9 A vs. 1.3 A) provide design margin
• Extended operating temperature range (-40°C to 130°C) supports broader environmental applications
• Tighter inductance tolerance (±15% vs. ±20%) improves circuit performance predictability
• Active product status with ROHS3 compliance and MSL 1 rating
• 4543 pieces available in current inventory

Selection between these parts depends on whether electromagnetic shielding is functionally required in the target application circuit.

Frequently Asked Questions (FAQ)

Q: Can P0250.334NLT replace UP5S-331-R in all applications?

A: P0250.334NLT is electrically compatible for inductance value, current rating, and saturation performance. The primary difference is shielding configuration. If the application requires electromagnetic shielding to prevent coupling with adjacent circuits or to meet EMI specifications, the shielded UP5S-331-R is required. If shielding is not specified, P0250.334NLT is a valid substitute.

Q: What is the significance of the DCR difference (500 mOhm vs. 560 mOhm)?

A: The P0250.334NLT DCR of 560 mOhm is 12% higher than the UP5S-331-R maximum of 500 mOhm. This increases resistive losses in the inductor. For applications where power dissipation or efficiency is critical, this difference must be evaluated against circuit requirements. For general filtering and impedance matching applications, this variance is typically acceptable.

Q: Are the physical dimensions compatible for PCB layout?

A: Both parts are classified as Nonstandard package form factor with similar dimensions. UP5S-331-R measures 18.40 × 15.00 × 7.50 mm while P0250.334NLT measures 18.62 × 15.14 × 7.36 mm. The differences are within typical PCB layout tolerances. Verify footprint compatibility with your specific PCB design before substitution.

Q: What is the temperature operating range difference impact?

A: UP5S-331-R operates from -25°C to 85°C while P0250.334NLT operates from -40°C to 130°C. If your application operates within the -25°C to 85°C range, both parts are suitable. If extended temperature operation is required, P0250.334NLT provides additional margin.

Q: How does inductance tolerance affect circuit performance?

A: UP5S-331-R has ±20% tolerance while P0250.334NLT has ±15% tolerance. Tighter tolerance improves circuit predictability and reduces performance variation across production batches. For precision filtering or resonant circuits, the ±15% tolerance of P0250.334NLT may provide superior performance consistency.

Q: Are both parts RoHS compliant?

A: Yes. Both UP5S-331-R and P0250.334NLT are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, suitable for standard manufacturing and storage conditions.
