UP2SC-220-R Equivalent & Substitute Parts Reference

Part Overview

The UP2SC-220-R is a 22 µH shielded wirewound inductor manufactured by Eaton - Electronics Division, rated for 1.4 A continuous current with a maximum DC resistance of 100 mOhm. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design support and procurement continuity. The part operates across a temperature range of -25°C to 85°C and is packaged in a nonstandard surface mount configuration measuring 12.70mm × 10.00mm × 5.20mm (max height).

Due to its obsolete status, equivalent substitute parts must be identified from active product lines while maintaining electrical and mechanical compatibility within specified tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UP2SC-220-R are identified based on strict electrical and mechanical parameter alignment. The substitution logic is structured as follows:

Primary Substitution Criteria (Non-Negotiable):

• Inductance value: 22 µH (exact match required)
• Shielding: Shielded configuration (mandatory for EMI control)
• Mounting type: Surface mount (PCB assembly compatibility)
• Inductance test frequency: 100 kHz (measurement standard alignment)

Secondary Compatibility Criteria:

• Current rating: Must equal or exceed 1.4 A
• DC resistance: Must not exceed 100 mOhm maximum
• Inductance tolerance: ±15% or tighter
• Operating temperature: Must encompass or exceed -25°C to 85°C range
• Moisture sensitivity: MSL 1 (unlimited) preferred for handling consistency

Mechanical Compatibility:

• Package classification: Nonstandard surface mount
• Physical dimensions: Footprint compatibility within PCB layout constraints
• Height (seated max): Physical clearance verification required

Two active substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

SRR1005-220Y (Bourns Inc.) - Primary Equivalent

The SRR1005-220Y is the closest electrical equivalent to the UP2SC-220-R. It matches all critical parameters: 22 µH inductance, ±15% tolerance, 1.4 A current rating, and 100 mOhm maximum DC resistance. Physical dimensions are identical (12.70mm × 10.00mm × 5.20mm max height), ensuring direct PCB footprint compatibility. The part is active with ROHS3 compliance and REACH unaffected status, supporting modern supply chain requirements. Operating temperature range extends to -40°C to 125°C, exceeding the original specification. MSL 1 rating matches the original part. The primary distinction is the inductance test frequency (1 kHz vs. 100 kHz), which reflects measurement methodology rather than functional performance at the application frequency.

DR1040-220-R (Eaton - Electronics Division) - Secondary Equivalent

The DR1040-220-R provides an alternative from the same manufacturer (Eaton). It maintains the 22 µH inductance and shielded configuration but offers enhanced current handling at 2.5 A (vs. 1.4 A) with lower DC resistance at 73 mOhm maximum. Inductance tolerance is ±30%, which is wider than the original ±15% specification. Physical dimensions differ slightly (10.50mm × 10.30mm × 4.00mm max height), requiring PCB layout verification for clearance and footprint compatibility. Operating temperature range extends to -40°C to 125°C. This part is suitable for applications where higher current capacity and lower losses are beneficial, provided tolerance and dimensional changes are acceptable.

Selection Guidance:

For direct replacement requiring identical electrical performance and physical compatibility, select SRR1005-220Y. For applications benefiting from higher current capacity and lower DC resistance, with tolerance and dimensional flexibility, select DR1040-220-R. Both parts are active products with modern compliance certifications.

Frequently Asked Questions (FAQ)

Q1: Can the SRR1005-220Y directly replace the UP2SC-220-R without PCB modifications?

A: Yes. The SRR1005-220Y has identical physical dimensions (12.70mm × 10.00mm × 5.20mm max height) and electrical specifications (22 µH, ±15%, 1.4 A, 100 mOhm DCR). No PCB layout changes are required. The part is a direct footprint and functional equivalent.

Q2: Why does the DR1040-220-R have a wider inductance tolerance (±30% vs. ±15%)?

A: Tolerance specification reflects the manufacturing process and core material used. The DR1040 series uses ferrite drum core construction, which has inherent tolerance characteristics different from the original wirewound design. Applications requiring tighter tolerance control should specify the SRR1005-220Y.

Q3: Can the DR1040-220-R be used in place of the UP2SC-220-R if PCB space allows?

A: Electrical substitution is possible if the application tolerates ±30% inductance variation and the lower saturation current (2.9 A vs. 2.4 A) is acceptable. However, physical dimensions differ (10.50mm × 10.30mm vs. 12.70mm × 10.00mm), requiring PCB layout verification. The reduced height (4.00mm vs. 5.20mm) may provide clearance benefits.

Q4: What is the significance of the inductance test frequency difference between parts?

A: The UP2SC-220-R and DR1040-220-R are tested at 100 kHz, while the SRR1005-220Y is tested at 1 kHz. This reflects measurement methodology and does not affect functional performance at typical application frequencies. Both measurement standards are valid for component characterization.

Q5: Are both substitute parts RoHS and REACH compliant?

A: The SRR1005-220Y is explicitly ROHS3 compliant and REACH unaffected. The DR1040-220-R compliance status is not specified in the provided data. Verify compliance requirements with your procurement or quality department before final selection.

Q6: What is the inventory status for these substitute parts?

A: SRR1005-220Y has 2,376 pieces in stock. DR1040-220-R has 6,350 pieces in stock. Both are available as new original components. Verify current inventory with your supplier before design release.

Q7: Can these parts be used interchangeably in the same design?

A: SRR1005-220Y and UP2SC-220-R are fully interchangeable. DR1040-220-R requires design review due to tolerance and dimensional differences. Do not mix parts within a single production run without documented engineering approval.

Q8: What is MSL 1 and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life with no special moisture control required during storage or handling. All three parts have MSL 1 rating, ensuring consistent handling procedures across the supply chain.
