USB4520-03-1-A Equivalent & Substitute Parts

Part Overview

The USB4520-03-1-A is a USB-C receptacle connector manufactured by GCT, designed for board edge and cutout mounting applications. This connector supports USB 2.0 specifications with 24 positions (16 active + 8 dummy contacts), rated for 5A current at 48VDC, and is qualified for 10,000 mating cycles. The connector features a mid-mount horizontal orientation with right-angle termination, gold-plated contacts, and steel shielding (SUS304). The product maintains Active status with ROHS3 compliance and UL94 V-0 flammability rating.

Substitute parts are necessary when specific mounting depth requirements differ from the primary specification, as the USB4520-03-1-A features a 2.1mm mid-mount depth. Alternative series within the GCT USB-C connector family provide equivalent electrical and mechanical performance with different mounting depths to accommodate varying PCB design constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB4520-03-1-A is determined by equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Connector Type: USB-C (USB TYPE-C)
• Specifications: USB 2.0
• Number of Contacts: 24 (16+8 Dummy)
• Gender: Receptacle
• Current Rating: 5A
• Voltage - Rated: 48VDC
• Mating Cycles: 10,000

Mechanical Equivalence Requirements:

• Mounting Type: Board Edge, Cutout; Surface Mount; Through Hole, Right Angle
• Mounting Feature: Horizontal, Mid Mount
• Termination: Solder
• Features: Solder Retention Tab

Material & Compliance Equivalence Requirements:

• Contact Finish: Gold
• Shell/Shielding Material: Steel (SUS304)
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Operating Temperature: -25°C ~ 85°C

Variable Parameter (Substitution Basis):

• Mid Mount Depth: The USB4520-03-1-A specifies 2.1mm depth. Substitute parts vary in mid-mount depth (0.8mm, 1.0mm, 1.6mm, 2.1mm) to accommodate different PCB design requirements while maintaining all other electrical and mechanical specifications.

All substitute parts listed maintain identical electrical performance, mechanical mounting compatibility, material specifications, and compliance certifications. Selection between substitutes depends solely on PCB cutout depth requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between USB4520-03-1-A and its substitutes is determined by PCB design requirements for mid-mount connector depth.

For 2.1mm Mid-Mount Depth Requirement: USB4520-03-1-A and USB4520-03-0-A are functionally identical. Both are Active status products with equivalent electrical and mechanical specifications. Selection between these two variants depends on packaging requirements or inventory availability.

For 1.6mm Mid-Mount Depth Requirement: USB4510-03-1-A provides equivalent electrical performance and compliance certifications with reduced mounting depth suitable for compact PCB designs.

For 1.0mm Mid-Mount Depth Requirement: USB4505-03-0-A delivers equivalent electrical specifications and compliance with further reduced mounting depth for space-constrained applications.

For 0.8mm Mid-Mount Depth Requirement: USB4500-03-0-A and USB4500-03-1-A provide the minimum mounting depth option while maintaining all electrical and mechanical equivalence. Both variants are Active status with full compliance certifications.

All substitute parts maintain identical current rating (5A), voltage rating (48VDC), mating cycle specification (10,000), operating temperature range (-25°C ~ 85°C), contact finish (Gold), shielding material (Steel SUS304), and termination method (Solder with retention tab).

Frequently Asked Questions (FAQ)

Q: What is the primary difference between USB4520-03-1-A and its substitute parts?

A: The primary difference is mid-mount connector depth. USB4520-03-1-A specifies 2.1mm depth. Substitute parts provide equivalent electrical and mechanical performance with alternative depths: USB4500 series (0.8mm), USB4505 series (1.0mm), and USB4510 series (1.6mm). All other specifications remain identical.

Q: Are all substitute parts electrically equivalent to USB4520-03-1-A?

A: Yes. All substitute parts maintain identical USB 2.0 specifications, 24-position contact configuration, 5A current rating, 48VDC voltage rating, 10,000 mating cycle specification, and gold-plated contact finish. Electrical performance is equivalent across all listed substitutes.

Q: Can USB4520-03-1-A be replaced with USB4500-03-1-A in existing designs?

A: Replacement is possible only if PCB cutout depth accommodates the 0.8mm mid-mount specification of USB4500-03-1-A. The original design specifies 2.1mm depth for USB4520-03-1-A. Physical PCB modification may be required for substitution with shallower-depth variants.

Q: Do all substitute parts share the same compliance certifications?

A: All listed substitute parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and Moisture Sensitivity Level 1 (Unlimited). All are Active status products from GCT. Compliance certifications are equivalent across all variants.
