UP2SC-100-R Equivalent & Substitute Parts Reference

Part Overview

The UP2SC-100-R is a 10 µH shielded wirewound inductor manufactured by Eaton - Electronics Division, rated for 2 A continuous current with a maximum DC resistance of 65 mOhm. This component operates across the temperature range of -25°C to 85°C and is packaged as a surface mount nonstandard form factor measuring 12.70mm × 10.00mm × 5.20mm (max height).

The UP2SC-100-R carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this inductance value and current rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP2SC-100-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 10 µH (exact match required)
• Inductance tolerance: ±20% or tighter
• Current rating: minimum 2 A continuous
• DC resistance: 65 mOhm maximum
• Shielding: shielded construction
• Mounting type: surface mount
• Moisture sensitivity: MSL 1 or equivalent

Secondary Compatibility Factors:

• Saturation current (Isat): minimum 3.41 A
• Operating temperature range: must encompass -25°C to 85°C minimum
• Package form factor: nonstandard surface mount compatible with 12.70mm × 10.00mm footprint envelope

The substitute parts identified below meet or exceed these electrical and mechanical parameters, ensuring functional equivalence within the specified operating conditions.

Engineering Selection Recommendations

DR1040-100-R (Eaton - Electronics Division):

The DR1040-100-R is an active product from the same manufacturer as the obsolete UP2SC-100-R. This part exceeds the electrical requirements of the main part with a 3.8 A current rating and lower DC resistance of 35 mOhm maximum. The extended operating temperature range (-40°C to 125°C) provides additional thermal margin. The DR1040-100-R is ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements. Physical dimensions are slightly reduced (10.50mm × 10.30mm footprint, 4.00mm max height), which may require PCB layout verification for space-constrained applications. Inductance tolerance is ±30%, which is wider than the original ±20% specification. Inventory availability is substantial at 25,219 pieces.

SRR1005-100M (Bourns Inc.):

The SRR1005-100M provides an exact electrical match to the UP2SC-100-R with identical inductance (10 µH), tolerance (±20%), current rating (2 A), and DC resistance (65 mOhm maximum). Physical dimensions and height are identical to the main part (12.70mm × 10.00mm × 5.20mm), ensuring direct PCB compatibility without layout modifications. The extended operating temperature range (-40°C to 125°C) exceeds the original specification. This part is ROHS3 compliant and REACH unaffected. Saturation current is 3 A, which is slightly lower than the main part's 3.41 A but remains within acceptable margins for the 2 A rated application. Inventory availability is excellent at 59,890 pieces. Cross-manufacturer substitution from Eaton to Bourns introduces supply chain diversification.

Both substitute parts satisfy the core electrical and mechanical requirements for functional equivalence. Selection between them depends on design constraints: the DR1040-100-R offers enhanced current capacity and lower losses, while the SRR1005-100M provides dimensional and electrical specification parity with the original component.

Frequently Asked Questions (FAQ)

Q: Can the DR1040-100-R replace the UP2SC-100-R in all applications?

A: The DR1040-100-R meets or exceeds all electrical parameters required by the UP2SC-100-R. However, the footprint dimensions differ slightly (10.50mm × 10.30mm versus 12.70mm × 10.00mm). PCB layout verification is necessary to confirm that the reduced footprint and lower profile (4.00mm versus 5.20mm) are compatible with existing circuit board designs and component placement constraints.

Q: What is the significance of the inductance tolerance difference between the main part and substitutes?

A: The UP2SC-100-R and SRR1005-100M both specify ±20% inductance tolerance, while the DR1040-100-R specifies ±30%. Inductance tolerance affects circuit performance in frequency-dependent applications. If the design requires tighter inductance control, the SRR1005-100M maintains the original ±20% specification. The DR1040-100-R's ±30% tolerance is acceptable for applications with wider design margins.

Q: Are there any compliance or regulatory differences between the substitute parts?

A: Both substitute parts are ROHS3 compliant and REACH unaffected. The original UP2SC-100-R does not specify RoHS or REACH status. If the application requires compliance with these regulations, both the DR1040-100-R and SRR1005-100M satisfy these requirements.

Q: How do the saturation current ratings affect substitution suitability?

A: The UP2SC-100-R has an Isat of 3.41 A, the DR1040-100-R has 4.4 A, and the SRR1005-100M has 3 A. For applications operating at or near the 2 A continuous current rating, the SRR1005-100M's 3 A saturation current provides adequate margin. The DR1040-100-R's higher saturation current offers additional headroom for transient current conditions.

Q: Can the SRR1005-100M be used as a direct drop-in replacement?

A: Yes. The SRR1005-100M matches the UP2SC-100-R in inductance, tolerance, current rating, DC resistance, physical dimensions, and height. No PCB layout modifications are required for direct substitution.

Q: What is the impact of the extended operating temperature range on substitute parts?

A: Both substitute parts operate from -40°C to 125°C, compared to the original -25°C to 85°C range. This extended range provides additional design margin and is beneficial for applications in extreme thermal environments. No negative impact results from the wider temperature specification.

Q: How should packaging format be considered in the substitution decision?

A: The DR1040-100-R and SRR1005-100M are supplied in Tape & Reel (TR) packaging, which is standard for automated assembly processes. If the application requires alternative packaging formats, this should be verified with the component supplier.
