Part Overview

The UP2UC-221-R is a 220 µH unshielded wirewound inductor manufactured by Eaton - Electronics Division, rated for 800 mA continuous current with a maximum DC resistance of 610 mOhm. This surface mount component operates across the temperature range of -25°C to 85°C and is classified as Active product status with RoHS compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP2UC-221-R is determined by the following critical parameters:

Primary Electrical Criteria:

• Inductance value: 220 µH (tolerance range ±20% acceptable)
• Current rating: minimum 800 mA continuous
• DC resistance: maximum 610 mOhm for primary substitute; up to 840 mOhm for secondary substitute with design verification
• Unshielded configuration required

Mechanical Criteria:

• Surface mount package type
• Nonstandard case dimensions compatible with board layout
• Moisture sensitivity level 1 (Unlimited)

Compliance Criteria:

• RoHS compliant or ROHS3 compliant status
• ECCN EAR99 classification
• HTSUS 8504.50.4000 tariff code

The identified substitute parts P0752.224NLT and SDR1005-221KL meet the core electrical specifications of 220 µH inductance at 800 mA rating. Variations in DC resistance, operating temperature range, and core material represent design trade-offs within acceptable substitution parameters.

Parameter Comparison

Engineering Selection Recommendations

P0752.224NLT (Pulse Electronics) - Primary Substitute:

The P0752.224NLT maintains identical inductance (220 µH) and current rating (800 mA) specifications. DC resistance increases from 610 mOhm to 840 mOhm maximum, representing a 37.7% increase in resistive losses. Operating temperature range extends to -40°C to 130°C, providing broader environmental coverage than the original part. ROHS3 compliance and EAR99 classification align with regulatory requirements. Physical dimensions show minor variations (0.510" L vs 0.500" L; 0.370" W vs 0.394" W; 0.215" H vs 0.205" H), requiring PCB layout verification. This substitute is suitable for applications where the elevated DCR is acceptable and extended temperature operation is beneficial.

SDR1005-221KL (Bourns Inc.) - Secondary Substitute:

The SDR1005-221KL provides 220 µH inductance with improved tolerance (±10% vs ±20%), reducing inductance variation. Continuous current rating is 700 mA, which is 100 mA below the original specification; saturation current remains at 800 mA. DC resistance reaches 780 mOhm maximum. The ferrite drum core construction differs from the original wirewound design. Operating temperature range is -40°C to 125°C. Physical dimensions match the original part length and width (0.500" L x 0.394" W), with reduced height (0.197" vs 0.205"). ROHS3 compliance and EAR99 classification are maintained. This substitute is applicable when the 700 mA continuous rating is sufficient for the application and tighter inductance tolerance is advantageous.

Compliance Status:

All three parts maintain EAR99 ECCN classification and 8504.50.4000 HTSUS code. RoHS compliance is confirmed across all variants. Moisture sensitivity level remains at MSL 1 (Unlimited) for all parts.

Frequently Asked Questions (FAQ)

Q: Can P0752.224NLT replace UP2UC-221-R in all applications?

A: P0752.224NLT is electrically compatible for applications where the increased DC resistance (840 mOhm vs 610 mOhm) does not exceed thermal or efficiency requirements. The 230 mOhm increase in DCR will generate proportionally higher resistive losses. PCB layout must accommodate the slightly larger footprint (0.510" L x 0.370" W vs 0.500" L x 0.394" W). Extended operating temperature range (-40°C to 130°C) provides additional environmental flexibility.

Q: Is SDR1005-221KL suitable for 800 mA continuous current applications?

A: SDR1005-221KL is rated for 700 mA continuous current, which is 100 mA below the UP2UC-221-R specification. Saturation current is 800 mA for both parts. Use of SDR1005-221KL in 800 mA continuous applications exceeds the rated current and is not recommended. This substitute is appropriate only for applications requiring 700 mA or less continuous current.

Q: What are the physical compatibility considerations?

A: UP2UC-221-R and SDR1005-221KL share identical length and width (0.500" L x 0.394" W), with SDR1005-221KL being slightly shorter (0.197" vs 0.205"). P0752.224NLT has minor dimensional differences (0.510" L x 0.370" W x 0.215" H) requiring PCB clearance verification. All three parts are surface mount with nonstandard case packages.

Q: How do inductance tolerances affect circuit performance?

A: UP2UC-221-R and P0752.224NLT both specify ±20% inductance tolerance, resulting in a range of 176 µH to 264 µH. SDR1005-221KL specifies ±10% tolerance, providing a tighter range of 198 µH to 242 µH. Tighter tolerance reduces circuit parameter variation and may improve performance consistency in frequency-dependent applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. UP2UC-221-R is RoHS Compliant. P0752.224NLT and SDR1005-221KL are both ROHS3 Compliant. All parts meet RoHS regulatory requirements.

Q: What is the impact of different core materials?

A: UP2UC-221-R and P0752.224NLT use wirewound construction with unspecified core material. SDR1005-221KL uses ferrite drum core construction. Ferrite cores typically provide better high-frequency performance and lower self-resonant frequency variation. Core material differences may affect frequency response characteristics and EMI performance in specific circuit applications.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability requires verification of three factors: (1) continuous current requirement must not exceed the substitute part rating; (2) DC resistance increase must be acceptable for thermal and efficiency budgets; (3) physical dimensions must fit PCB layout constraints. SDR1005-221KL is not interchangeable for 800 mA applications due to its 700 mA rating. P0752.224NLT requires thermal analysis due to elevated DCR.
