USB4055-30-A Equivalent & Substitute Parts

Part Overview

The USB4055-30-A is a USB-C receptacle connector manufactured by GCT, designed for USB 3.2 Gen 2 applications. This 24-position surface mount, right-angle connector operates at 5A current rating with a 20VDC voltage specification and supports 10,000 mating cycles. The connector features a horizontal mounting orientation with board guide and solder retention tab, suitable for applications requiring high-speed USB data transfer with robust mechanical durability. As an active product with ROHS3 compliance and UL94 V-0 flammability rating, substitute parts may be required due to inventory availability, specific voltage requirements, or alternative mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the USB4055-30-A is determined by the following core parameters: connector type (USB-C receptacle), contact count (24 positions), USB specification (USB 3.2 Gen 2), current rating (5A), mating cycles (10,000), shielding (shielded), contact finish (gold), and flammability rating (UL94 V-0). All listed substitute parts maintain these core electrical and mechanical characteristics.

Substitute parts are grouped into two categories based on voltage rating and operating temperature range:

Category 1 (20VDC, -40°C ~ 85°C): USB4065-30-A matches the voltage specification and extended low-temperature operating range of the main part. This substitute maintains identical electrical performance parameters.

Category 2 (48VDC, -25°C ~ 85°C): USB4056-03-A, USB4080-03-A, and USB4525-03-A operate at higher voltage ratings (48VDC) with a narrower low-temperature range (-25°C ~ 85°C). These parts are electrically compatible for applications not requiring the extended -40°C low-temperature specification, and support higher voltage environments.

Differences in shell/shielding material (Steel Stainless vs. SUS301 vs. SUS304), mounting feature variations (horizontal vs. horizontal mid-mount), and packaging formats (Tape & Reel vs. Cut Tape) do not affect functional substitution within the same voltage category.

Parameter Comparison

Engineering Selection Recommendations

USB4065-30-A is the primary direct substitute for USB4055-30-A. Both parts share identical voltage rating (20VDC), operating temperature range (-40°C ~ 85°C), and mounting feature (horizontal). This part maintains full electrical and thermal compatibility with the original specification.

USB4056-03-A, USB4080-03-A, and USB4525-03-A are suitable substitutes for applications where the extended -40°C low-temperature specification is not required and higher voltage tolerance (48VDC) is acceptable. These parts support the same USB 3.2 Gen 2 specification, current rating, and mating cycle count. Selection among these three depends on mounting configuration requirements: USB4056-03-A and USB4080-03-A maintain standard surface mount right-angle orientation, while USB4525-03-A provides board edge, cutout mounting with mid-mount feature for alternative PCB layout configurations.

All substitute parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and active product status, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can USB4056-03-A, USB4080-03-A, or USB4525-03-A be used in applications requiring -40°C operation?

A: No. These parts are rated for -25°C minimum operating temperature. Applications requiring -40°C operation must use USB4055-30-A or USB4065-30-A.

Q: What is the difference between USB4080-03-A and USB4056-03-A?

A: Both parts operate at 48VDC with -25°C ~ 85°C temperature range and maintain identical electrical specifications. The primary difference is packaging format: USB4080-03-A is supplied in Cut Tape (CT) & Digi-Reel format, while USB4056-03-A is supplied in Tape & Reel (TR) format. Shell material differs slightly (Steel SUS304 vs. SUS301), but this does not affect functional compatibility.

Q: Is USB4525-03-A compatible with standard surface mount assembly processes?

A: USB4525-03-A features board edge, cutout mounting with mid-mount orientation, requiring different PCB layout and assembly approach compared to standard surface mount right-angle connectors. This part is suitable only for applications with board edge connector requirements.

Q: Can I substitute a 48VDC-rated part in a 20VDC application?

A: Yes. Parts rated for 48VDC (USB4056-03-A, USB4080-03-A, USB4525-03-A) are electrically compatible in 20VDC applications. The higher voltage rating provides additional safety margin. However, verify that operating temperature requirements do not exceed -25°C minimum.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and UL94 V-0 flammability rating, ensuring regulatory equivalence with the main part.
