UJ2-BV-1-TH USB-B Receptacle Connector Equivalent & Substitute Parts

Part Overview

The UJ2-BV-1-TH is a USB 2.0 Type-B receptacle connector manufactured by CUI Devices, designed for through-hole vertical mounting applications. This 4-position shielded connector operates at 1A current rating with a 30VAC voltage specification and supports 1500 mating cycles. The part is Active status and ROHS3 compliant, making it suitable for industrial and consumer electronics requiring reliable USB connectivity.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements demand extended operating temperature ranges, higher current ratings, or when alternative manufacturers offer superior lead times and inventory availability.

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the UJ2-BV-1-TH. Selection should be based on the following criteria:

For Direct Replacement (Identical Operating Conditions): 614004141221 (Würth Elektronik) provides identical temperature range and insulation color match with enhanced current rating (1.5A vs 1A), making it suitable for direct substitution without design modification.

For Extended Temperature Range Applications: 61400413321 (Würth Elektronik) extends operating temperature to -40°C ~ 105°C, supporting applications requiring broader thermal performance. KUSBVX-BS1N-B, KUSBVX-BS1N-B30, and KUSBVX-BS1N-W (Kycon, Inc.) provide -55°C ~ 85°C range for low-temperature environments.

For High-Inventory Availability: KUSBVX-BS1N-W (Kycon, Inc.) offers 11,145 units in stock, providing supply chain flexibility. USB-B-S-VT (Adam Tech) maintains 4,086 units with 1.5A current rating.

For Specific Insulation Color Requirements: Black insulation: UJ2-BV-1-TH, 614004141221, KUSBVX-BS1N-B, KUSBVX-BS1N-B30, USB-B-S-VT, USB-B-S-F-B-VT White insulation: 61400413321, A-USB B-TOP-C, KUSBVX-BS1N-W, USB-B-S-S-B-VT-R Natural insulation: SS-52300-002

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher current rating than the UJ2-BV-1-TH? A: Yes. Substitute parts with current ratings of 1.5A are fully compatible with applications designed for 1A operation. Higher current ratings indicate enhanced capability and do not create compatibility issues.

Q: Are all substitute parts suitable for the same PCB footprint? A: All listed substitutes share identical mounting specifications: through-hole vertical mounting with 4-position solder termination and board lock features. PCB footprint compatibility is maintained across all substitutes.

Q: What is the significance of shell material differences (Brass vs. Copper vs. Phosphor Bronze)? A: Shell material variations do not affect electrical performance or USB 2.0 compliance. Material selection reflects manufacturing process differences among suppliers. All materials provide equivalent shielding effectiveness and mechanical durability.

Q: Can I substitute a part with an extended operating temperature range in a standard temperature application? A: Yes. Parts rated for extended temperature ranges (-40°C ~ 105°C or -55°C ~ 85°C) are fully compatible with standard temperature applications (-20°C ~ 85°C). Extended ratings indicate superior thermal stability without introducing compatibility concerns.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the UJ2-BV-1-TH.

Q: What does "Board Lock" feature mean? A: Board lock is a mechanical retention feature that secures the connector to the PCB during mating and unmating cycles, preventing accidental disconnection and improving mechanical reliability in high-vibration environments.

Q: Can I mix different substitute parts in the same design? A: Yes. All substitute parts are electrically and mechanically interchangeable. Mixed usage across multiple connector positions on the same PCB is supported without performance degradation.
