Key Parameters

Substitute Part Grouping Explanation

Substitute components for the UP2SC-330-R are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Core Electrical Parameters:

• Inductance value: 33 µH (exact match required)
• Inductance tolerance: ±15% or tighter
• Current rating: minimum 1.2 A
• DC resistance: 160 mOhm maximum
• Shielding: shielded configuration

Mechanical Parameters:

• Mounting type: surface mount
• Physical dimensions: compatible with 12.70mm x 10.00mm x 5.20mm envelope
• Package type: nonstandard

Environmental Parameters:

• Operating temperature range: minimum -25°C to 85°C coverage
• Moisture sensitivity: MSL 1 (Unlimited)

Two active substitute parts meet these criteria: the DR1040-330-R (Eaton - Electronics Division) and the SRR1005-330Y (Bourns Inc.). Both components maintain the 33 µH inductance specification and surface mount configuration while offering enhanced current ratings and extended temperature ranges compared to the obsolete UP2SC-330-R.

Engineering Selection Recommendations

SRR1005-330Y (Bourns Inc.) - Primary Substitute

The SRR1005-330Y is the closest electrical equivalent to the UP2SC-330-R. It maintains identical inductance (33 µH), inductance tolerance (±15%), current rating (1.2 A), and DC resistance (160 mOhm maximum). Physical dimensions are identical (12.70mm x 10.00mm x 5.20mm), ensuring direct footprint compatibility. The component is active with ROHS3 compliance and REACH unaffected status, supporting modern regulatory requirements. Extended operating temperature range (-40°C to 125°C) provides enhanced thermal margin. Inventory availability is substantial at 4500 pieces.

DR1040-330-R (Eaton - Electronics Division) - Secondary Substitute

The DR1040-330-R offers enhanced electrical performance with higher current rating (2.2 A) and lower DC resistance (93 mOhm maximum), suitable for applications requiring increased current capacity. Inductance value remains 33 µH. Physical dimensions differ slightly (10.50mm x 10.30mm x 4.00mm), requiring PCB layout verification. Inductance tolerance is ±30%, which may impact precision-dependent circuits. The component is active with ROHS3 compliance and REACH unaffected status. Inventory availability is 2000 pieces.

Selection Criteria:

• For direct replacement with identical electrical specifications: SRR1005-330Y
• For applications requiring higher current capacity: DR1040-330-R
• Both substitutes support modern compliance standards (ROHS3, REACH)
• Both are active products with established supply chains

Frequently Asked Questions (FAQ)

Q1: Can the SRR1005-330Y directly replace the UP2SC-330-R without PCB modifications?

A: Yes. The SRR1005-330Y maintains identical physical dimensions (12.70mm x 10.00mm x 5.20mm), inductance value (33 µH), inductance tolerance (±15%), current rating (1.2 A), and DC resistance (160 mOhm maximum). Direct footprint compatibility is confirmed.

Q2: What are the key differences between the two substitute options?

A: The SRR1005-330Y provides electrical parameter matching with the original part. The DR1040-330-R offers higher current rating (2.2 A vs 1.2 A) and lower DC resistance (93 mOhm vs 160 mOhm), but has different physical dimensions (10.50mm x 10.30mm x 4.00mm) and wider inductance tolerance (±30%).

Q3: Does the DR1040-330-R require PCB layout changes?

A: Yes. The DR1040-330-R has different physical dimensions (10.50mm x 10.30mm x 4.00mm) compared to the UP2SC-330-R (12.70mm x 10.00mm x 5.20mm). PCB footprint verification is required before implementation.

Q4: Are both substitute parts compliant with current regulatory standards?

A: Yes. Both the SRR1005-330Y and DR1040-330-R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q5: What is the inductance tolerance difference between substitutes?

A: The SRR1005-330Y maintains ±15% tolerance, matching the original UP2SC-330-R. The DR1040-330-R has ±30% tolerance, which may affect circuit performance in precision applications.

Q6: Which substitute has better inventory availability?

A: The SRR1005-330Y has the highest inventory availability at 4500 pieces, followed by the DR1040-330-R at 2000 pieces.

Q7: What is the operating temperature range for each substitute?

A: Both substitutes support -40°C to 125°C, extending beyond the original UP2SC-330-R range of -25°C to 85°C, providing enhanced thermal margin for demanding applications.

Q8: Can the DR1040-330-R be used in applications designed for 1.2 A current?

A: Yes. The DR1040-330-R is rated for 2.2 A continuous current, exceeding the 1.2 A requirement. The lower DC resistance (93 mOhm) reduces power dissipation in the inductor, improving overall circuit efficiency.
