UP2C-4R7-R Equivalent & Substitute Parts Reference

Part Overview

The UP2C-4R7-R is a 4.7 µH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division, rated for 5.62 A continuous current with 11.7 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 supply chain reliability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP2C-4R7-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 4.7 µH (fixed requirement)
• Inductance tolerance: ±20% (fixed requirement)
• Core type: Drum core, ferrite construction
• Shielding configuration: Unshielded
• Mounting type: Surface mount
• Package classification: Nonstandard

Secondary Compatibility Criteria:

• Current rating: Minimum 4.5 A (substitute must support the application's current demands)
• DC resistance: Maximum 33 mOhm (higher DCR acceptable within thermal budget constraints)
• Saturation current: Minimum 5.4 A
• Operating temperature: Minimum -40°C to 85°C overlap required
• Moisture sensitivity: MSL 1 (Unlimited)

All substitute parts listed meet the primary matching criteria and fall within acceptable ranges for secondary parameters. Substitutes are grouped by active product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Highest Compatibility): B82476B1472M100 from EPCOS - TDK Electronics is the preferred substitute. This part maintains drum core ferrite construction identical to the main part, offers superior current rating (5.3 A vs. 4.5 A minimum among alternatives), and features the lowest DC resistance among active alternatives at 16.5 mOhm maximum. The component holds AEC-Q200 automotive qualification and ROHS3 compliance, with extended operating temperature range (-55°C to 150°C) providing additional thermal margin. Tape & Reel packaging supports high-volume production requirements.

Secondary Substitute (Ferrite Core Alternative): SDR1005-4R7ML from Bourns Inc. provides drum core ferrite construction with active product status and ROHS3 compliance. DC resistance of 19 mOhm maximum remains within acceptable thermal parameters. Operating temperature range (-40°C to 125°C) covers the original specification. This option is suitable when B82476B1472M100 availability is constrained.

Tertiary Substitute (Wirewound Alternative): P0751.472NLT from Pulse Electronics (Tape & Reel packaging) or P0751.472NL (bulk packaging) represent wirewound construction alternatives. Both maintain 4.7 µH inductance and ±20% tolerance with active product status and ROHS3 compliance. Higher DC resistance (33 mOhm maximum) requires thermal analysis to confirm acceptability in the target application. Current rating of 4.8 A is lower than the main part; applications requiring the full 5.62 A rating should not use this substitute without design verification.

Compliance Considerations: All active substitutes comply with ROHS3 and REACH requirements. MSL 1 (Unlimited) rating across all parts ensures compatibility with standard PCB assembly processes. Selection should prioritize parts with active product status to ensure long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can B82476B1472M100 directly replace UP2C-4R7-R without circuit modification?

A: B82476B1472M100 is electrically compatible for applications operating at or below 5.3 A continuous current. The 4.7 µH inductance, ±20% tolerance, and unshielded drum core ferrite construction match the original specification. DC resistance increase from 11.7 mOhm to 16.5 mOhm maximum generates additional heat; verify thermal performance in your specific application. No circuit modification is required for standard inductor applications.

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

A: DC resistance directly affects power dissipation (P = I²R). The UP2C-4R7-R dissipates 0.370 W at 5.62 A (11.7 mOhm × 5.62² A). B82476B1472M100 at 5.3 A dissipates 0.464 W (16.5 mOhm × 5.3² A). P0751.472NLT at 4.8 A dissipates 0.762 W (33 mOhm × 4.8² A). Confirm PCB thermal design accommodates increased dissipation, particularly for P0751 series alternatives.

Q: Are P0751.472NL and P0751.472NLT interchangeable?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging: P0751.472NL is supplied in bulk, while P0751.472NLT is supplied in Tape & Reel format. Select based on your assembly process requirements. Tape & Reel packaging is standard for automated pick-and-place assembly.

Q: Does SDR1005-4R7ML meet the original operating temperature specification?

A: SDR1005-4R7ML operates from -40°C to 125°C, which covers the UP2C-4R7-R specification of -40°C to 85°C. The extended upper temperature limit (125°C vs. 85°C) provides additional margin. This part is suitable for applications within the original temperature range.

Q: What is the significance of AEC-Q200 certification on B82476B1472M100?

A: AEC-Q200 is an automotive qualification standard for passive components. This certification indicates the part has undergone rigorous reliability testing and is approved for automotive applications. If your application requires automotive-grade components, B82476B1472M100 is the appropriate choice among the listed substitutes.

Q: Can I use SDR1005-4R7ML in applications requiring the full 5.62 A rating?

A: No. SDR1005-4R7ML is rated for 4.5 A continuous current, which is 0.8 A below the original specification. Using this part at 5.62 A will cause saturation and thermal stress. Applications requiring the full 5.62 A rating should use B82476B1472M100 (5.3 A) or UP2C-4R7-R if available. For lower-current applications (≤4.5 A), SDR1005-4R7ML is acceptable.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts (B82476B1472M100, P0751.472NL, P0751.472NLT, and SDR1005-4R7ML) are ROHS3 compliant. The original UP2C-4R7-R RoHS status is not specified in the documentation. Verify RoHS compliance requirements for your end application and supply chain.
