UP2SC-3R0-R Equivalent & Substitute Parts

Part Overview

The UP2SC-3R0-R is a 3 µH shielded wirewound inductor manufactured by Eaton - Electronics Division, part of the UNI-PAC™ 2SC series. This component is rated for 2.9 A continuous current with a maximum DC resistance of 30 mOhm and operates across the temperature range of -25°C to 85°C. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP2SC-3R0-R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Inductance value: 3 µH
• Inductance tolerance: ±20%
• Current rating: 2.9 A minimum
• DC resistance: 30 mOhm maximum
• Shielding: Shielded construction required
• Mounting type: Surface Mount
• Physical footprint: 12.70 mm × 10.00 mm × 5.20 mm (height max)
• Moisture sensitivity: MSL 1 or better

The SRR1005-3R0M from Bourns Inc. meets all mandatory matching criteria and is classified as an active product with current manufacturing support and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The SRR1005-3R0M from Bourns Inc. is the qualified substitute for the obsolete UP2SC-3R0-R. Selection is based on the following engineering factors:

Functional Equivalence: All critical electrical parameters match exactly: 3 µH inductance, 2.9 A current rating, and 30 mOhm maximum DC resistance. Physical footprint and mounting configuration are identical, enabling direct board-level replacement without layout modification.

Product Status: The SRR1005-3R0M is an active product with current manufacturing support and documented inventory availability (1112 pcs in stock). The UP2SC-3R0-R is obsolete with no ongoing production.

Regulatory Compliance: The SRR1005-3R0M carries ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Compliance documentation for the obsolete UP2SC-3R0-R is not specified.

Operating Envelope: The SRR1005-3R0M operates across -40°C to 125°C, which encompasses the original part's -25°C to 85°C range, providing extended thermal margin for system reliability.

Packaging: The SRR1005-3R0M is supplied in Tape & Reel format, standard for high-volume manufacturing and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the SRR1005-3R0M be used as a direct replacement for UP2SC-3R0-R in existing designs?

A: Yes. The SRR1005-3R0M meets all mandatory electrical and mechanical parameters: identical inductance (3 µH), current rating (2.9 A), DC resistance (30 mOhm max), shielding, and physical dimensions (12.70 × 10.00 × 5.20 mm). No circuit redesign or board layout modification is required.

Q: What are the key differences between these two parts?

A: The primary differences are product status and core material. The UP2SC-3R0-R is obsolete; the SRR1005-3R0M is active. The SRR1005-3R0M uses a drum core ferrite construction versus the UP2SC-3R0-R wirewound design. The SRR1005-3R0M provides extended operating temperature range (-40°C to 125°C vs. -25°C to 85°C) and carries current regulatory certifications (ROHS3, REACH).

Q: Are there any performance differences in Q factor or self-resonant frequency?

A: The parts exhibit different Q characteristics due to core material differences. The UP2SC-3R0-R specifies Q of 70 @ 100 kHz with self-resonant frequency of 65 MHz. The SRR1005-3R0M specifies Q of 25 @ 7.96 MHz with self-resonant frequency of 80 MHz. These differences do not affect substitution validity for applications requiring the specified inductance, current rating, and DC resistance parameters.

Q: What is the packaging format for the SRR1005-3R0M?

A: The SRR1005-3R0M is supplied in Tape & Reel (TR) format, standard for surface mount component assembly. The UP2SC-3R0-R packaging format is not specified in available documentation.

Q: Are both parts MSL 1 rated?

A: Yes. Both the UP2SC-3R0-R and SRR1005-3R0M carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture precautions are required during storage or handling.

Q: What is the ECCN and HTSUS classification for the substitute part?

A: The SRR1005-3R0M carries ECCN EAR99 and HTSUS 8504.50.4000, identical to the original UP2SC-3R0-R, indicating no change in export control or tariff classification.
