A-USBSB USB-B Receptacle Connector Equivalent & Substitute Parts

Part Overview

The A-USBSB is an active USB 2.0 Type-B receptacle connector manufactured by Assmann WSW Components. This through-hole, right-angle mounted connector features a 4-position design with board lock functionality, rated for 1.5A at operating temperatures from -55°C to 85°C. The connector is RoHS3 compliant and suitable for applications requiring reliable USB 2.0 device-side connectivity. Substitute parts are identified to provide design flexibility, inventory alternatives, and sourcing options while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the A-USBSB are grouped into two categories based on substitution classification:

MFR Recommended Substitutes maintain full electrical and mechanical compatibility with identical or superior specifications:

• 292304-1 (TE Connectivity AMP Connectors)
• UE27BC54130 (Amphenol ICC)

Parametric Equivalents satisfy core functional requirements with minor specification variations:

• USB-B-S-F-W-TH (Samtec Inc.)
• USB-B-S-S-B-TH (Samtec Inc.)

All substitute parts share the following critical parameters with the main part:

• USB 2.0 Type-B receptacle connector
• 4-position through-hole, right-angle mounting
• Solder termination with board lock feature
• 1500 mating cycle rating
• UL94 V-0 flammability rating
• MSL 1 (Unlimited) moisture sensitivity
• ROHS3 compliance or equivalent RoHS status
• EAR99 ECCN classification

Parameter Comparison

Engineering Selection Recommendations

292304-1 (TE Connectivity AMP Connectors) is the primary MFR recommended substitute. This part maintains identical mounting and electrical specifications with RoHS compliance and REACH unaffected status. The 1A per contact rating is suitable for standard USB 2.0 applications. Shielding is provided, enhancing EMI performance compared to the main part.

UE27BC54130 (Amphenol ICC) is the secondary MFR recommended substitute. This part matches the 1.5A current rating of the main part and provides shielding. Operating temperature range is -40°C to 85°C, which is narrower than the main part but suitable for most commercial and industrial applications. ROHS3 compliance and REACH unaffected status are confirmed.

USB-B-S-F-W-TH and USB-B-S-S-B-TH (Samtec Inc.) are parametric equivalents suitable for applications where current rating specification is not critical. Both parts maintain the core USB 2.0 Type-B receptacle functionality, through-hole right-angle mounting, and board lock feature. Operating temperature range is -50°C to 85°C. ROHS3 compliance and REACH unaffected status are confirmed. These parts are supplied in bulk packaging rather than trays.

All substitute parts maintain active product status and meet the same flammability and moisture sensitivity requirements as the main part.

Frequently Asked Questions (FAQ)

Q: Can 292304-1 be used as a direct replacement for A-USBSB?

A: Yes. Both parts are USB 2.0 Type-B receptacle connectors with 4-position through-hole right-angle mounting, solder termination, and board lock features. The 1A per contact rating of 292304-1 is suitable for standard USB 2.0 device applications. Shielding in 292304-1 provides additional EMI protection.

Q: What is the difference between MFR Recommended and Parametric Equivalent substitutes?

A: MFR Recommended substitutes (292304-1 and UE27BC54130) are manufacturer-designated alternatives with full electrical and mechanical compatibility. Parametric Equivalents (USB-B-S-F-W-TH and USB-B-S-S-B-TH) satisfy core functional requirements but may have minor specification variations, such as unspecified current ratings or different packaging formats.

Q: Does UE27BC54130 work in applications requiring -55°C operation?

A: UE27BC54130 operates from -40°C to 85°C. Applications requiring -55°C operation should use A-USBSB or USB-B-S-F-W-TH / USB-B-S-S-B-TH, which operate to -50°C or -55°C respectively.

Q: What is the difference between USB-B-S-F-W-TH and USB-B-S-S-B-TH?

A: Both are Samtec parametric equivalents with identical electrical and mechanical specifications. The primary difference is insulation color: USB-B-S-F-W-TH has white insulation, while USB-B-S-S-B-TH has black insulation. Both are supplied in bulk packaging.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are RoHS3 compliant or equivalent RoHS compliant. The main part A-USBSB is ROHS3 compliant.

Q: Can Samtec parts be used in applications where current rating is specified as 1.5A?

A: Samtec parts USB-B-S-F-W-TH and USB-B-S-S-B-TH do not specify current rating. For applications with explicit 1.5A current requirements, use A-USBSB or UE27BC54130.

Q: What packaging formats are available?

A: A-USBSB, 292304-1, and UE27BC54130 are supplied in trays. USB-B-S-F-W-TH and USB-B-S-S-B-TH are supplied in bulk packaging. Packaging selection depends on assembly process requirements and inventory management practices.
