Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped based on strict equivalence of the following critical parameters:

Primary Equivalence Criteria:

• Connector Type: USB-B (USB TYPE-B)
• Specifications: USB 2.0
• Number of Contacts: 4
• Gender: Receptacle
• Mounting Type: Through Hole
• Mounting Feature: Vertical
• Termination: Solder
• Features: Board Lock
• Shielding: Shielded
• Contact Finish: Gold
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in operating temperature range, current rating, shell/shielding material composition, and insulation color do not affect functional interchangeability in standard USB 2.0 through-hole applications where the connector footprint and electrical interface remain constant.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance certification, meeting regulatory requirements for current manufacturing and deployment. The USB-B-S-F-W-VT and its substitutes are functionally equivalent for USB 2.0 through-hole receptacle applications requiring vertical mounting with board lock features.

Selection among substitute parts should be based on:

Inventory Availability: KUSBVX-BS1N-W (Kycon, Inc.) offers the highest inventory level at 11,145 pieces, followed by USB-B-S-F-B-VT (Samtec Inc.) at 2,723 pieces.

Manufacturer Consistency: Samtec Inc. substitutes (USB-B-S-F-B-VT, USB-B-S-F-W-VT-R, USB-B-S-S-B-VT-R) maintain identical electrical specifications and certifications to the primary part.

Cross-Manufacturer Options: Würth Elektronik (61400413321, 614004141221), Kycon Inc. (KUSBVX-BS1N-B, KUSBVX-BS1N-W), CUI Devices (UJ2-BV-1-TH), Assmann WSW Components (A-USB B-TOP-C), and Stewart Connector (SS-52300-002) provide qualified alternatives with equivalent core parameters.

Compliance Status: All parts carry ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, suitable for standard PCB assembly and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can USB-B-S-F-W-VT be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts share identical connector type (USB-B), specifications (USB 2.0), contact configuration (4-position receptacle), mounting method (through-hole vertical), termination type (solder), and board lock features. The physical footprint and electrical interface are equivalent, enabling direct substitution in standard applications.

Q: What is the difference between Samtec substitutes (USB-B-S-F-B-VT, USB-B-S-F-W-VT-R, USB-B-S-S-B-VT-R) and the primary part?

A: The Samtec substitutes differ only in insulation color designation (B for black, W for white) and minor part number suffixes. All maintain identical electrical ratings (30VAC, 1500 mating cycles), shielding, contact finish (gold), and flammability rating (UL94 V-0). These variations do not affect functional performance.

Q: Are there operating temperature differences among substitute parts?

A: Operating temperature ranges vary across manufacturers. Samtec parts specify -50°C to 85°C or -20°C to 85°C. Würth Elektronik specifies -40°C to 105°C or -20°C to 85°C. Kycon specifies -55°C to 85°C. Assmann and CUI specify -20°C to 85°C. Selection should account for application temperature requirements, though all parts support standard industrial operating ranges.

Q: What is the significance of the "R" suffix in part numbers like USB-B-S-F-W-VT-R?

A: The "R" suffix indicates a revision or variant designation within the Samtec product line. This does not affect electrical or mechanical equivalence for USB 2.0 receptacle applications. The part remains functionally interchangeable with the primary USB-B-S-F-W-VT.

Q: Do all substitute parts have the same mating cycle rating?

A: Most substitute parts specify 1500 mating cycles, matching the primary part. Assmann (A-USB B-TOP-C) and Stewart Connector (SS-52300-002) do not provide mating cycle specifications in available data. For applications requiring specific cycle life documentation, Samtec, Würth Elektronik, Kycon, and CUI Devices parts provide explicit 1500-cycle ratings.

Q: Which substitute offers the best inventory availability?

A: KUSBVX-BS1N-W (Kycon, Inc.) provides the highest inventory at 11,145 pieces. This part is suitable for high-volume production requirements or immediate availability needs.

Q: Are there shell material differences among substitutes?

A: Yes. Samtec parts use Phosphor Bronze. Würth Elektronik uses Brass. Kycon and Stewart Connector use Copper Alloy. Assmann uses Copper. These material variations do not affect electrical performance or mechanical compatibility in standard USB 2.0 applications.

Q: Can I mix substitute parts from different manufacturers in the same design?

A: Yes. All substitute parts meet identical core electrical and mechanical specifications. However, for consistency in manufacturing, testing, and supply chain management, using parts from a single manufacturer is recommended where possible.
