UP2SC-180-R Equivalent & Substitute Parts

Part Overview

The UP2SC-180-R is an 18 µH shielded wirewound inductor manufactured by Eaton - Electronics Division, designed for surface mount applications with a current rating of 1.6 A and maximum DC resistance of 90 mOhm. This component is part of the UNI-PAC™ 2SC series and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UP2SC-180-R are identified based on strict electrical and mechanical parameter matching. The substitution logic requires:

Critical Matching Parameters:

• Inductance value of 18 µH with ±15% tolerance
• Current rating of 1.6 A or greater
• Maximum DC resistance of 90 mOhm
• Shielded construction for EMI control
• Surface mount packaging
• Physical dimensions of 12.70mm x 10.00mm x 5.20mm (maximum seated height)

Secondary Compatibility Parameters:

• Self-resonant frequency at or above 19 MHz
• Operating temperature range that encompasses the original specification or extends it

The SRR1005-180Y from Bourns Inc. meets all critical matching parameters and is therefore classified as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The SRR1005-180Y from Bourns Inc. is a direct functional equivalent to the obsolete UP2SC-180-R. Selection of this substitute is based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters match exactly, including inductance, tolerance, current rating, and DC resistance. The self-resonant frequency is identical at 19 MHz.

Mechanical Compatibility: Physical dimensions and mounting characteristics are identical, ensuring direct PCB footprint compatibility without layout modifications.

Product Status: The SRR1005-180Y is an active product with current manufacturing support, addressing the obsolescence issue of the original UP2SC-180-R.

Compliance and Certifications: The SRR1005-180Y carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications.

Operating Environment: The substitute part's extended operating temperature range (-40°C ~ 125°C) provides greater thermal margin compared to the original specification (-25°C ~ 85°C), making it suitable for applications across a broader temperature envelope.

Availability: The SRR1005-180Y is available in active inventory (944 pcs) with standard tape and reel packaging, supporting both prototype and production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the SRR1005-180Y be used as a direct replacement for UP2SC-180-R without circuit modifications?

A: Yes. The SRR1005-180Y is electrically and mechanically equivalent to the UP2SC-180-R. All critical parameters including inductance, current rating, DC resistance, shielding, and physical dimensions match exactly. No circuit modifications are required.

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

A: The primary differences are product status and operating temperature range. The UP2SC-180-R is obsolete, while the SRR1005-180Y is an active product. The SRR1005-180Y operates across -40°C to 125°C compared to the original -25°C to 85°C range. The SRR1005-180Y also carries ROHS3 compliance certification.

Q: Are the package dimensions identical?

A: Yes. Both parts have identical physical dimensions of 12.70mm length x 10.00mm width x 5.20mm maximum seated height. They use identical surface mount packaging and will fit the same PCB footprint without modification.

Q: What is the saturation current difference, and does it affect substitution?

A: The UP2SC-180-R has a saturation current (Isat) of 2.5A, while the SRR1005-180Y has 2.1A. Both exceed the 1.6A rated current, providing adequate margin. The lower saturation current of the substitute does not prevent substitution for applications operating at or below the 1.6A rating.

Q: Is the SRR1005-180Y available in the same packaging format?

A: The SRR1005-180Y is supplied in tape and reel (TR) packaging, which is standard for production environments. The original UP2SC-180-R packaging format is not specified in the available data. Tape and reel packaging is compatible with automated assembly equipment.

Q: Do both parts meet the same regulatory classifications?

A: Yes. Both parts share identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications. The SRR1005-180Y additionally carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Q: What is the difference in Q factor between these inductors?

A: The UP2SC-180-R has a Q of 60 at 100 kHz, while the SRR1005-180Y has a Q of 35 at 2.52 MHz. These measurements are taken at different frequencies and reflect different core materials (wirewound vs. drum core ferrite). For applications operating at the specified frequencies, both parts perform within their respective design parameters.
