USB-B USB 2.0 Receptacle Connector A-USB/2-B/SMT Equivalent & Substitute Parts

Part Overview

The A-USB/2-B/SMT is a USB-B USB 2.0 receptacle connector manufactured by Assmann WSW Components, designed for surface mount, right-angle applications. This 4-position connector is specified for 1.5A current rating and operates across -55°C to 85°C. The part is active in production status and ROHS3 compliant, making it suitable for modern electronic assemblies requiring USB 2.0 Type-B connectivity. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component sourcing flexibility and supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A-USB/2-B/SMT are identified based on strict alignment of the following critical parameters:

• Connector Type: USB-B (USB TYPE-B)
• Specifications: USB 2.0
• Number of Contacts: 4
• Gender: Receptacle
• Mounting Type: Surface Mount, Right Angle
• Mounting Feature: Horizontal
• Termination: Solder
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The substitute parts 1734346-1 and 1734346-4, both manufactured by TE Connectivity AMP Connectors, meet these core electrical and mechanical requirements. Both parts are active in production status and maintain equivalent connector topology and solder termination characteristics. Differences in operating temperature range, current rating, and voltage rating are noted in the parameter comparison table and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both 1734346-1 and 1734346-4 are active production parts from TE Connectivity AMP Connectors and maintain ROHS3 compliance and UL94 V-0 flammability certification consistent with the A-USB/2-B/SMT. All three parts share identical connector topology, contact count, mounting configuration, and solder termination characteristics.

Selection between the main part and substitutes depends on application-specific operating conditions. The A-USB/2-B/SMT supports extended temperature operation from -55°C to 85°C and provides 1.5A current capacity. The TE Connectivity alternatives (1734346-1 and 1734346-4) operate within 0°C to 50°C and are rated for 1A current. Applications requiring the full temperature range or higher current capacity of the A-USB/2-B/SMT cannot use the TE Connectivity substitutes. Applications operating within 0°C to 50°C and requiring 1A or less current capacity may use either substitute part.

Frequently Asked Questions (FAQ)

Q: Can 1734346-1 or 1734346-4 be used as direct replacements for A-USB/2-B/SMT?

A: Direct replacement is possible only when application operating temperature remains within 0°C to 50°C and current requirements do not exceed 1A. The A-USB/2-B/SMT supports -55°C to 85°C operation and 1.5A current rating. If your application requires extended temperature range or higher current capacity, the A-USB/2-B/SMT is the appropriate choice.

Q: What are the key differences between these USB-B connectors?

A: All three parts share identical USB 2.0 Type-B receptacle topology, 4-contact configuration, surface mount right-angle mounting, and solder termination. The primary differences are operating temperature range (A-USB/2-B/SMT: -55°C to 85°C versus TE Connectivity: 0°C to 50°C) and current rating (A-USB/2-B/SMT: 1.5A versus TE Connectivity: 1A). Shell material composition also differs: Assmann uses brass while TE Connectivity uses phosphor bronze, steel, and stainless steel.

Q: Are 1734346-1 and 1734346-4 electrically identical?

A: Yes. Both TE Connectivity parts share identical electrical specifications including USB 2.0 compliance, 4-contact configuration, 1A current rating, 30VAC voltage rating, and 1500 mating cycles. Both are ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Q: What packaging format is used for these connectors?

A: All three parts are supplied in tray packaging, suitable for automated assembly processes and component handling.

Q: Are these parts suitable for high-reliability applications?

A: All three parts meet UL94 V-0 flammability requirements and ROHS3 compliance standards. Mating cycle rating is 1500 for all parts. Selection for high-reliability applications must account for operating temperature and current requirements specific to your application.
