UP5S-330-R Equivalent & Substitute Parts

Part Overview

The UP5S-330-R is a 33 µH shielded wirewound inductor manufactured by Eaton - Electronics Division, part of the UNI-PAC™ 5S series. This surface mount component is rated for 2.8 A continuous current with a maximum DC resistance of 60 mOhm and operates across the temperature range of -25°C to 85°C. The component is ROHS3 compliant and carries an unlimited moisture sensitivity level (MSL 1).

The UP5S-330-R is currently in active production status with 766 pieces available in new original inventory. Substitute parts are identified when equivalent inductance values, current ratings, and mounting specifications are required but alternative manufacturers or performance characteristics are acceptable for specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UP5S-330-R are identified based on the following core electrical and mechanical parameters:

Primary Matching Criteria:

• Inductance value: 33 µH (exact match required)
• Inductance test frequency: 100 kHz
• Mounting type: Surface Mount
• Package classification: Nonstandard
• Component type: Wirewound inductor

Acceptable Variation Parameters:

• Current rating: Substitute must meet or exceed 2.8 A minimum
• DC resistance: Substitute DCR must not exceed 60 mOhm maximum by more than 10%
• Operating temperature range: Substitute must cover or exceed the -25°C to 85°C range
• Inductance tolerance: Substitute tolerance of ±15% or tighter is acceptable
• Shielding: Both shielded and unshielded configurations are evaluated based on application electromagnetic compatibility requirements

The P0250.333NLT from Pulse Electronics qualifies as a substitute based on matching inductance, exceeding current rating capability, and maintaining compatible DC resistance and temperature operating range.

Engineering Selection Recommendations

UP5S-330-R Selection Criteria:

• Applications requiring shielded inductor configuration to minimize electromagnetic interference
• Circuits operating within -25°C to 85°C temperature range
• Systems where Eaton component qualification or supply chain continuity is specified
• Current draw up to 2.8 A continuous operation

P0250.333NLT Selection Criteria:

• Applications where unshielded inductor configuration is acceptable or preferred
• Circuits requiring extended temperature operation (-40°C to 130°C)
• Systems benefiting from higher current saturation margin (5.5 A vs 4.25 A)
• Applications where Pulse Electronics component qualification is established
• Supply chain scenarios where Pulse Electronics inventory availability is advantageous (7658 pieces vs 766 pieces)

Both components are ROHS3 compliant, carry MSL 1 rating, and maintain active product status. The primary engineering consideration is the shielding configuration difference: the UP5S-330-R provides electromagnetic shielding, while the P0250.333NLT operates unshielded. This distinction determines suitability based on circuit layout, adjacent component placement, and EMI/RFI requirements.

Frequently Asked Questions (FAQ)

Q: Can the P0250.333NLT directly replace the UP5S-330-R in all applications?

A: Direct replacement is possible for applications where unshielded inductor operation is acceptable. The primary difference is shielding configuration. If the original design requires shielding for EMI control or circuit isolation, the unshielded substitute may not be suitable without circuit redesign validation.

Q: What is the significance of the 6 mOhm difference in DC resistance?

A: The P0250.333NLT has a maximum DCR of 66 mOhm compared to the UP5S-330-R at 60 mOhm maximum. This 10% increase results in slightly higher power dissipation at rated current. For a 2.8 A load, the difference is approximately 47 mW additional dissipation. This is acceptable for most applications but should be verified in thermal-sensitive designs.

Q: Are the physical dimensions compatible for PCB layout?

A: Yes. The P0250.333NLT dimensions (18.62 mm L x 15.14 mm W x 7.36 mm H) vary less than 2% from the UP5S-330-R (18.40 mm L x 15.00 mm W x 7.50 mm H). Both components fit within standard nonstandard package footprints and are compatible with existing PCB layouts.

Q: What is the impact of the ±15% tolerance on the P0250.333NLT versus ±20% on the UP5S-330-R?

A: The tighter ±15% tolerance on the P0250.333NLT provides better inductance consistency across production batches. For circuits with tight inductance specifications, the substitute offers improved performance. For applications with wider tolerance margins, both components are equivalent.

Q: Can the extended temperature range of the P0250.333NLT (-40°C to 130°C) be used in place of the UP5S-330-R (-25°C to 85°C)?

A: Yes. The extended range is a superset of the original specification. The P0250.333NLT operates safely across the full -25°C to 85°C range required by the UP5S-330-R and extends capability to -40°C and up to 130°C for applications requiring broader temperature operation.

Q: What compliance certifications apply to both components?

A: Both the UP5S-330-R and P0250.333NLT are ROHS3 compliant, carry MSL 1 (unlimited moisture sensitivity), and are classified under HTSUS code 8504.50.4000 with ECCN designation EAR99. Both meet equivalent regulatory requirements for industrial and commercial applications.
