A-USB-A-E-R Equivalent & Substitute Parts

Part Overview

The A-USB-A-E-R is a USB-A (USB TYPE-A) USB 1.1 receptacle connector manufactured by Assmann WSW Components. This connector features 4 positions, through-hole right-angle mounting with vertical flag configuration, and is rated for 1.5A current at operating temperatures from -55°C to 85°C. The part is currently obsolete, making identification of compatible substitute components essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

The A-USB A-E qualifies as a direct substitute for the A-USB-A-E-R based on the following alignment of critical parameters:

Matching Parameters:

• Connector Type: USB-A (USB TYPE-A)
• Number of Contacts: 4
• Gender: Receptacle
• Mounting Type: Through Hole, Right Angle
• Mounting Feature: Vertical, Flag
• Termination: Solder
• Current Rating: 1.5A
• Operating Temperature Range: -55°C ~ 85°C
• Mating Cycles: 1500
• Contact Finish: Gold
• Shell/Shielding Material: Brass
• Material Flammability Rating: UL94 V-0
• Insulation Color: White
• Moisture Sensitivity Level: 1 (Unlimited)

The primary technical difference is the USB specification upgrade from USB 1.1 to USB 2.0 in the substitute part. This represents a backward-compatible enhancement, as USB 2.0 receptacles maintain full electrical and mechanical compatibility with USB 1.1 host interfaces while providing increased bandwidth capability for future applications.

Parameter Comparison

Engineering Selection Recommendations

The A-USB A-E is the appropriate substitute for the obsolete A-USB-A-E-R. The substitute part maintains identical mechanical and electrical characteristics across all critical parameters including mounting configuration, current rating, temperature range, and contact specifications. The upgrade from USB 1.1 to USB 2.0 specification provides enhanced capability without compromising backward compatibility or requiring design modifications.

The A-USB A-E is currently in active production status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment for new designs and legacy system support. The substitute part is available in tray packaging with significantly higher inventory levels (6970 units) compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the A-USB A-E be used as a direct replacement for the A-USB-A-E-R without PCB modifications?

A: Yes. The A-USB A-E maintains identical through-hole mounting dimensions, right-angle orientation, vertical flag configuration, and solder termination as the original part. No PCB layout changes are required.

Q: What is the significance of the USB 2.0 upgrade in the substitute part?

A: USB 2.0 is backward compatible with USB 1.1 host interfaces. The receptacle maintains the same physical connector geometry and electrical pin configuration. Systems designed for USB 1.1 operation will function without modification, while the connector supports higher bandwidth for future applications.

Q: Are there any compliance or certification differences between the two parts?

A: The A-USB A-E includes ROHS3 compliance certification, whereas the original A-USB-A-E-R does not specify RoHS status. Both parts share identical UL94 V-0 flammability ratings and REACH unaffected status. The substitute part meets current regulatory requirements for new applications.

Q: What is the packaging difference, and does it affect component selection?

A: The A-USB-A-E-R was supplied in unspecified packaging, while the A-USB A-E is supplied in tray packaging. Tray packaging is standard for automated assembly processes and does not affect the component's electrical or mechanical performance.

Q: Are the current rating and operating temperature specifications identical?

A: Yes. Both parts are rated for 1.5A current and operate across the identical temperature range of -55°C to 85°C. Mating cycle ratings of 1500 cycles are also identical, ensuring equivalent mechanical durability.
