Equivalent & Substitute Parts for UP0.4C-2R2-R

Part Overview

The UP0.4C-2R2-R is a 2.2 µH unshielded drum core wirewound inductor manufactured by Eaton Electronics Division, part of the UNI-PAC™ 0.4C series. This surface mount component is rated for 2.15 A continuous current with a maximum DC resistance of 50mOhm and operates across the temperature range of -40°C to 85°C. The component is RoHS compliant and classified as Moisture Sensitivity Level 1 (unlimited). Substitute parts are necessary when the primary component is unavailable, when extended temperature range operation is required, or when alternative sourcing is preferred for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP0.4C-2R2-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 2.2 µH (±20% tolerance band)
• Inductance test frequency: 100 kHz
• Mounting type: Surface Mount
• Package dimensions: 0.260" L x 0.175" W (6.60mm x 4.45mm)
• Height (seated): 0.115" (2.92mm) maximum
• Shielding configuration: Unshielded

Secondary Compatibility Parameters:

• Current rating: Minimum 2.15 A (substitute parts rated 2.3 A or higher are acceptable)
• DC resistance: Maximum 50mOhm (substitute parts with higher DCR values require thermal analysis verification)
• Saturation current: Minimum 2.38 A
• Operating temperature range: Minimum -40°C to 85°C coverage
• RoHS compliance status

The substitute parts listed below meet the primary matching criteria and maintain electrical compatibility within the specified parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Highest Compatibility):

The P0770.222NLT (Pulse Electronics) and SDR6603-2R2M (Bourns Inc.) are classified as direct manufacturer substitutes. Both components maintain identical physical dimensions, inductance values, and tolerance specifications. The P0770.222NLT offers extended temperature range operation to 130°C and is supplied in Tape & Reel packaging. The SDR6603-2R2M provides ferrite drum core construction matching the original design and extends temperature range to 125°C. Both substitute parts carry ROHS3 compliance and REACH unaffected status.

Similar Substitute (Alternative Sourcing):

The P0770.222NL (Pulse Electronics) is classified as a similar substitute and provides equivalent electrical performance. This part shares the same inductance, tolerance, current rating, and physical dimensions as the direct substitutes. The primary distinction is packaging configuration. ROHS3 compliance and REACH unaffected status are maintained.

Parameter Deviations:

All substitute parts exhibit increased DC resistance (70mOhm maximum) compared to the original UP0.4C-2R2-R (50mOhm maximum). This 40% increase in DCR results in proportionally higher power dissipation under rated current conditions. Applications operating at or near the 2.15 A current rating require thermal analysis to confirm acceptable operating temperatures within the specified range.

All substitute parts maintain saturation current ratings at or above 2.3 A, which is within the original specification of 2.38 A saturation current.

Compliance Status:

All listed substitute parts maintain RoHS compliance (ROHS3 standard) and Moisture Sensitivity Level 1 classification. The Pulse Electronics parts (P0770.222NLT and P0770.222NL) and Bourns part (SDR6603-2R2M) carry REACH unaffected status, confirming regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can P0770.222NLT be used as a direct replacement for UP0.4C-2R2-R in all applications?

A: P0770.222NLT matches all critical physical and electrical parameters including inductance value, tolerance, mounting type, and package dimensions. The higher DC resistance (70mOhm vs. 50mOhm) increases power dissipation. Applications operating continuously at 2.15 A require thermal verification to confirm the component remains within the -40°C to 130°C operating range under actual circuit conditions.

Q: What is the difference between the P0770.222NLT and P0770.222NL?

A: Both parts are manufactured by Pulse Electronics with identical electrical specifications and physical dimensions. The primary difference is packaging: P0770.222NLT is supplied in Tape & Reel format, while P0770.222NL packaging is not specified in the provided data. Both maintain equivalent performance characteristics and regulatory compliance.

Q: Why do the substitute parts have higher DC resistance than the original?

A: The substitute parts (P0770.222NLT, SDR6603-2R2M, P0770.222NL) all specify 70mOhm maximum DC resistance compared to the original 50mOhm specification. This difference reflects different winding designs and core material processing between manufacturers. The higher DCR results in increased resistive losses, which must be evaluated in thermal-sensitive applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original UP0.4C-2R2-R is RoHS compliant. All three substitute parts (P0770.222NLT, SDR6603-2R2M, P0770.222NL) carry ROHS3 compliance certification, confirming adherence to current RoHS standards.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All parts maintain identical physical dimensions (0.260" L x 0.175" W, 0.115" maximum height) and surface mount configuration. PCB footprints and pick-and-place programming require no modification. However, thermal design review is necessary if the application operates at continuous currents near 2.15 A due to the increased DC resistance of substitute parts.

Q: What is the saturation current specification, and why does it matter?

A: Saturation current (Isat) is the DC current level at which the inductor's inductance value begins to degrade significantly. The original part specifies 2.38 A saturation current. All substitute parts specify 2.3 A saturation current. For applications where peak or transient currents approach or exceed 2.3 A, the original UP0.4C-2R2-R provides slightly higher saturation margin.

Q: Are there any REACH or environmental compliance differences between these parts?

A: The Pulse Electronics parts (P0770.222NLT and P0770.222NL) and Bourns part (SDR6603-2R2M) all carry REACH unaffected status, indicating no REACH substance of concern restrictions. All parts maintain Moisture Sensitivity Level 1 (unlimited) classification, requiring no special moisture control during storage or handling.
