AUSB1-DFN-PTP1 USB-C Connector Equivalent & Substitute Parts

Part Overview

The AUSB1-DFN-PTP1 is a USB-C (USB TYPE-C) receptacle connector manufactured by Assumann WSW Components, designed for USB 3.2 Gen 2 applications. This 24-position surface mount, right-angle connector supports high-speed data transfer with a rated current of 3A at 5V and accommodates 10,000 mating cycles. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing design support, legacy system maintenance, and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AUSB1-DFN-PTP1 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector Type: USB-C (USB TYPE-C)
• Specification: USB 3.2 Gen 2 (USB 3.1 Gen 2, Superspeed +)
• Number of Contacts: 24
• Gender: Receptacle
• Mounting Type: Surface Mount, Right Angle; Through Hole
• Mounting Feature: Horizontal
• Termination: Solder

Secondary Compatibility Criteria:

• Operating Temperature Range: Must support minimum -25°C ~ 105°C
• Current Rating: Must support minimum 3A
• Voltage Rating: Must support minimum 5V
• Mating Cycles: Must support minimum 10,000 cycles
• Contact Finish: Gold
• RoHS Compliance: ROHS3 Compliant

The substitute part USB4056-03-A meets all primary compatibility criteria and exceeds secondary criteria in current rating (5A vs. 3A) and voltage rating (48VDC vs. 5V), while maintaining equivalent mechanical and electrical performance for USB 3.2 Gen 2 applications.

Parameter Comparison

Engineering Selection Recommendations

The USB4056-03-A is a direct functional substitute for the obsolete AUSB1-DFN-PTP1. Both connectors are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute part is manufactured by GCT and maintains active product status, ensuring long-term availability and supply chain continuity.

The USB4056-03-A exceeds the electrical specifications of the original part with a 5A current rating versus 3A, and supports 48VDC versus 5V. The operating temperature range of the substitute (-25°C ~ 85°C) is narrower than the original (-25°C ~ 105°C); applications requiring operation above 85°C must be evaluated against actual system requirements.

Both parts share identical mechanical compatibility: 24-position receptacle, surface mount right-angle configuration with horizontal mounting feature, solder termination, and 10,000 mating cycle rating. The substitute incorporates additional features including board guide and solder retention stake, with SUS301 shielding material providing enhanced corrosion resistance compared to the steel shell of the original.

Frequently Asked Questions (FAQ)

Q: Can USB4056-03-A directly replace AUSB1-DFN-PTP1 in existing designs?

A: Yes. Both connectors share identical USB-C receptacle configuration, 24-contact count, surface mount right-angle mounting, and solder termination. Mechanical and electrical compatibility is confirmed across all primary parameters.

Q: What is the difference in operating temperature range?

A: The AUSB1-DFN-PTP1 operates from -25°C to 105°C, while the USB4056-03-A operates from -25°C to 85°C. Applications requiring sustained operation above 85°C must evaluate whether the substitute meets thermal requirements.

Q: Does the USB4056-03-A support the same USB 3.2 Gen 2 specification?

A: Yes. Both connectors are specified for USB 3.2 Gen 2 (USB 3.1 Gen 2, Superspeed +) with identical 24-position contact configuration and gold contact finish.

Q: What packaging is available for the substitute part?

A: The USB4056-03-A is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both the AUSB1-DFN-PTP1 and USB4056-03-A are ROHS3 compliant and REACH unaffected.

Q: What is the difference in current rating between the two connectors?

A: The AUSB1-DFN-PTP1 is rated for 3A, while the USB4056-03-A is rated for 5A. The substitute provides higher current capacity for the same form factor.

Q: Does the substitute part include any additional features?

A: Yes. The USB4056-03-A includes board guide and solder retention stake features, and uses SUS301 shielding material for improved corrosion resistance compared to the steel shell of the original part.
