UP2SC-6R8-R Equivalent & Substitute Parts

Part Overview

The UP2SC-6R8-R is a 6.8 µH shielded wirewound inductor manufactured by Eaton - Electronics Division, designed for surface mount applications requiring 2.2 A current rating and 55mOhm maximum DC resistance. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity.

The primary reason for identifying substitute parts is the obsolete status of the UP2SC-6R8-R. Active production alternatives with matching electrical and mechanical specifications ensure design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UP2SC-6R8-R are identified based on strict alignment of the following critical parameters:

Mandatory Matching Criteria:

• Inductance value: 6.8 µH (exact match)
• Current rating: 2.2 A (minimum requirement)
• Shielding type: Shielded construction
• Mounting configuration: Surface mount
• Physical package dimensions: 12.70mm x 10.00mm x 5.20mm (nonstandard case)
• Tolerance: ±20%

Allowable Variation Parameters:

• DC Resistance (DCR): Substitute parts may exceed the 55mOhm maximum specification of the original part, provided the increase does not compromise circuit performance in the target application
• Current saturation (Isat): Substitute parts may have different saturation current ratings
• Operating temperature range: Substitute parts may have extended or different temperature ranges
• Product status: Active production parts are preferred over obsolete parts

The SRR1005-6R8M from Bourns Inc. meets all mandatory matching criteria and is therefore classified as a direct functional equivalent.

Engineering Selection Recommendations

Primary Substitute: SRR1005-6R8M (Bourns Inc.)

The SRR1005-6R8M is the recommended substitute for the obsolete UP2SC-6R8-R based on the following engineering factors:

1. Electrical Equivalence: Inductance, current rating, and tolerance specifications are identical. The component satisfies the core functional requirements of the original design.

2. Physical Compatibility: Package dimensions are identical (12.70mm x 10.00mm x 5.20mm), ensuring direct PCB footprint compatibility without layout modifications.

3. Product Status: The SRR1005-6R8M is in active production, providing long-term supply chain availability and procurement reliability.

4. Regulatory Compliance: The substitute part is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

5. DC Resistance Consideration: The SRR1005-6R8M has a maximum DCR of 75mOhm compared to the original 55mOhm specification. This 20mOhm increase results in proportionally higher power dissipation. Circuit designers must confirm that this additional power loss does not exceed thermal design margins in the target application.

6. Saturation Current: The SRR1005-6R8M has a lower saturation current (2.8 A vs. 3.9 A). Designs operating near the 2.2 A rated current must confirm that the reduced saturation margin does not compromise performance under transient or fault conditions.

7. Operating Temperature: The extended operating range (-40°C ~ 125°C) of the substitute part provides additional environmental flexibility compared to the original specification (-25°C ~ 85°C).

Frequently Asked Questions (FAQ)

Q: Can the SRR1005-6R8M be used as a direct drop-in replacement for the UP2SC-6R8-R?

A: The SRR1005-6R8M is physically and electrically compatible for most applications. However, two parameters differ: DC resistance is 20mOhm higher (75mOhm vs. 55mOhm), and saturation current is 1.1 A lower (2.8 A vs. 3.9 A). Circuit designers must confirm these differences do not exceed design margins for power dissipation and current headroom in the specific application.

Q: What is the impact of the higher DC resistance in the SRR1005-6R8M?

A: Higher DC resistance increases power dissipation according to P = I²R. At the rated 2.2 A current, the additional 20mOhm resistance results in approximately 0.097 W additional power loss compared to the original part. Thermal design analysis is required to confirm this increase is acceptable within the PCB thermal environment.

Q: Does the lower saturation current of the SRR1005-6R8M affect circuit performance?

A: The saturation current specification indicates the current level at which the inductor begins to lose inductance due to core saturation. The SRR1005-6R8M saturates at 2.8 A compared to 3.9 A for the original part. Since the rated current is 2.2 A, normal operation remains within specification. However, transient overcurrent conditions or fault scenarios must be evaluated to ensure the reduced saturation margin is acceptable.

Q: Are there any packaging or supply chain differences between these parts?

A: The UP2SC-6R8-R is obsolete with no active production. The SRR1005-6R8M is actively manufactured by Bourns Inc. and available in Tape & Reel packaging. Procurement should reference the SRR1005-6R8M for new designs and ongoing supply requirements.

Q: What compliance certifications apply to the SRR1005-6R8M?

A: The SRR1005-6R8M is ROHS3 compliant and REACH unaffected. Both certifications meet current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Can the operating temperature range difference affect my design?

A: The SRR1005-6R8M operates from -40°C to 125°C, compared to -25°C to 85°C for the original part. If your application operates within the original temperature range, the substitute part provides additional margin. If your application requires operation below -25°C or above 85°C, the substitute part extends the usable range.
