UP2C-2R2-R Equivalent & Substitute Parts Reference

Part Overview

The UP2C-2R2-R is a 2.2 µH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division, rated for 7.5 A continuous current with 6.6 mOhm DC resistance. This component operates across the temperature range of -40°C to 85°C and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP2C-2R2-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 2.2 µH (fixed)
• Inductance tolerance: ±20% (fixed)
• Core material: Ferrite (fixed)
• Shielding configuration: Unshielded (fixed)
• Mounting type: Surface Mount (fixed)
• Moisture sensitivity: MSL 1 (fixed)

Secondary Compatibility Parameters:

• Current rating: Substitute must support minimum 7.5 A continuous current
• DC resistance: Substitute DCR must not exceed 6.6 mOhm to maintain equivalent electrical performance
• Saturation current (Isat): Substitute must support minimum 8.67 A
• Operating temperature range: Substitute must cover or exceed -40°C to 85°C

All substitute parts listed meet or exceed the primary matching criteria. Secondary parameters are evaluated to determine functional equivalence and application suitability.

Parameter Comparison

Engineering Selection Recommendations

SDR1005-2R2ML (Bourns Inc.): This substitute is active and ROHS3 compliant. The current rating of 6.1 A is below the original 7.5 A specification, and the saturation current of 7.0 A is below the original 8.67 A. The DC resistance of 12 mOhm exceeds the original 6.6 mOhm. This part is suitable for applications where the original 7.5 A rating is not a hard requirement and where the increased DC resistance is acceptable. The extended operating temperature range to 125°C provides additional thermal margin.

B82476B1222M100 (EPCOS - TDK Electronics): This substitute is active, ROHS3 compliant, and carries AEC-Q200 automotive qualification. The current rating of 6.7 A approaches the original 7.5 A specification more closely than other substitutes. The saturation current of 7.0 A and DC resistance of 10.5 mOhm represent a compromise between the original specifications and other available options. The extended operating temperature range to 150°C and automotive qualification make this part suitable for demanding applications.

P0751.222NLT (Pulse Electronics): This substitute is active and ROHS3 compliant, supplied in Tape & Reel packaging. The current rating of 6.1 A and saturation current of 7.0 A are identical to the Bourns option. The DC resistance of 15 mOhm is the highest among substitutes. The operating temperature range extends to 130°C. This part is suitable where tape and reel packaging is required for automated assembly.

Frequently Asked Questions (FAQ)

Q: Can the SDR1005-2R2ML directly replace the UP2C-2R2-R in all applications?

A: The SDR1005-2R2ML matches the inductance value and tolerance but has a lower current rating (6.1 A versus 7.5 A) and higher DC resistance (12 mOhm versus 6.6 mOhm). Direct substitution is valid only for applications where the circuit operates below 6.1 A continuous current and where the increased DC resistance does not degrade circuit performance.

Q: What is the impact of increased DC resistance in substitute parts?

A: Higher DC resistance increases power dissipation in the inductor. For the UP2C-2R2-R with 6.6 mOhm, power loss at 7.5 A is approximately 371 mW. The SDR1005-2R2ML at 12 mOhm would dissipate 446 mW at the same current. This difference must be evaluated against thermal design margins in the target application.

Q: Which substitute offers the best thermal performance?

A: The B82476B1222M100 offers the widest operating temperature range (-55°C to 150°C) and includes AEC-Q200 automotive qualification, indicating validated performance across extended temperature extremes. This part is recommended for applications requiring robust thermal performance.

Q: Are all substitutes available in the same packaging format?

A: No. The SDR1005-2R2ML and B82476B1222M100 are supplied in Tape & Reel (TR) packaging. The P0751.222NLT is also available in Tape & Reel. The P0751.222NL variant is available without specified packaging. Verify packaging requirements for your assembly process.

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

A: All listed parts, including the original UP2C-2R2-R, share the same ±20% tolerance. This tolerance applies to all substitutes and does not differentiate between options. Circuit designs must account for this tolerance range regardless of which part is selected.

Q: Can I use the P0751.222NLT in high-frequency applications?

A: The P0751.222NLT specifications do not include self-resonant frequency or Q factor data. The SDR1005-2R2ML provides Q of 51 at 2.47 MHz and self-resonant frequency of 65 MHz. For high-frequency applications, the SDR1005-2R2ML offers documented frequency performance characteristics.

Q: Is RoHS compliance required for my application?

A: All active substitute parts (SDR1005-2R2ML, B82476B1222M100, P0751.222NLT) are ROHS3 compliant. The original UP2C-2R2-R RoHS status is not specified. If RoHS compliance is a requirement, all listed substitutes meet this criterion.
