A-USBPB-2-R USB-B Connector Equivalent & Substitute Parts

Part Overview

The A-USBPB-2-R is a USB-B (USB TYPE-B) USB 2.0 plug connector manufactured by Assmann WSW Components. This 4-position free hanging (in-line) solder connector is designed for applications requiring standard USB 2.0 Type-B connectivity. The part is currently listed as obsolete, making identification of active equivalent and substitute parts essential for ongoing procurement and design continuity. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A-USBPB-2-R are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Connector Type: USB-B (USB TYPE-B)
• Specifications: USB 2.0
• Number of Contacts: 4
• Gender: Plug
• Mounting Type: Free Hanging (In-Line)
• Termination: Solder
• Number of Ports: 1

Secondary Electrical Criteria:

• Current Rating: Minimum 1.0A per Contact (1.5A preferred)
• Voltage Rating: Minimum 30V
• Operating Temperature Range: Must encompass or match -55°C ~ 85°C

Material & Compliance Criteria:

• Contact Finish: Gold
• Shell/Shielding Material: Steel
• Material Flammability Rating: UL94 V-0 or equivalent
• Moisture Sensitivity Level: MSL 1

Two active substitute parts meet these criteria and are available for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

A-USBPB-2 (Assmann WSW Components) is the primary substitute for A-USBPB-2-R. This part is manufactured by the same original equipment manufacturer, maintains identical electrical specifications (1.5A per Contact, 30VAC), and carries the same material flammability rating (UL94 V-0). The part is currently active with robust inventory availability. RoHS3 compliance is confirmed. This substitute provides the highest degree of compatibility and is suitable for direct replacement in all applications.

1002-029-02300 (CNC Tech) is a secondary substitute that meets core USB-B connector requirements and maintains mechanical compatibility. However, this part operates at a reduced current rating of 1.0A per Contact compared to the 1.5A specification of the main part. The material flammability rating and insulation color are not specified in available documentation. This part is suitable for applications where the 1.0A current rating is sufficient and where the unspecified material properties do not conflict with design requirements. RoHS3 compliance is confirmed.

Frequently Asked Questions (FAQ)

Q: Can A-USBPB-2 be used as a direct replacement for A-USBPB-2-R?

A: Yes. A-USBPB-2 is a direct substitute. Both parts share identical connector type (USB-B), specifications (USB 2.0), contact configuration (4-position), mounting method (free hanging in-line), termination type (solder), current rating (1.5A per Contact), voltage rating (30VAC), contact finish (gold), shell material (steel), and flammability rating (UL94 V-0). The primary difference is product status: A-USBPB-2-R is obsolete while A-USBPB-2 is active.

Q: What is the key limitation of the 1002-029-02300 substitute?

A: The 1002-029-02300 operates at a maximum current rating of 1.0A per Contact, whereas the original A-USBPB-2-R and primary substitute A-USBPB-2 are rated for 1.5A per Contact. Applications requiring current levels between 1.0A and 1.5A per Contact cannot use this substitute. Additionally, material flammability rating and insulation color specifications are not provided for this part.

Q: Are there packaging differences between the substitutes?

A: Yes. A-USBPB-2 is supplied in bulk packaging, while 1002-029-02300 is supplied in tray packaging. Packaging selection depends on procurement volume and assembly process requirements. Both parts maintain identical electrical and mechanical specifications regardless of packaging format.

Q: Do the substitute parts meet RoHS compliance?

A: Both substitute parts (A-USBPB-2 and 1002-029-02300) are ROHS3 compliant. RoHS compliance status for the original A-USBPB-2-R is not specified in available documentation.

Q: What is the operating temperature range for these connectors?

A: A-USBPB-2 maintains the same operating temperature range as the original part: -55°C ~ 85°C. The operating temperature range for 1002-029-02300 is not specified in available documentation.

Q: Are all three parts suitable for solder termination?

A: Yes. All three parts (A-USBPB-2-R, A-USBPB-2, and 1002-029-02300) use solder termination and are compatible with standard PCB assembly processes for through-hole or free-hanging in-line mounting applications.
