Substitute Part Grouping Explanation

Substitution eligibility for the USB-A-S-RA-SMT-HD-T/R is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: USB-A (USB TYPE-A)
• Specifications: USB 2.0
• Number of Contacts: 4
• Gender: Receptacle
• Mounting Type: Surface Mount, Right Angle; Through Hole
• Mounting Feature: Horizontal
• Termination: Solder
• Shielding: Shielded
• Contact Finish: Gold
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute part 629104151021 (Würth Elektronik) meets all mandatory matching parameters and is classified as a parametric equivalent. Variations in electrical ratings (current, voltage, mating cycles) and operating temperature ranges do not preclude substitution when the application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the USB-A-S-RA-SMT-HD-T/R and 629104151021 are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Selection between these parts should be based on application-specific electrical and mechanical requirements:

The USB-A-S-RA-SMT-HD-T/R supports higher current capacity (2A versus 1.5A) and higher voltage rating (250VAC versus 30VAC), making it suitable for applications requiring maximum electrical headroom. The higher mating cycle rating (5000 versus 1500) indicates greater durability for high-frequency connection/disconnection scenarios.

The 629104151021 remains suitable for standard USB 2.0 applications where current draw does not exceed 1.5A and mating cycles remain below 1500. Both parts share identical mechanical and compliance characteristics, ensuring PCB layout and assembly process compatibility.

Frequently Asked Questions (FAQ)

Q: Can 629104151021 be used as a direct replacement for USB-A-S-RA-SMT-HD-T/R?

A: Yes, 629104151021 is a parametric equivalent for applications where the electrical requirements do not exceed 1.5A current draw and 1500 mating cycles. Both connectors share identical mechanical form factor, mounting type, and compliance certifications. Verify that your application's current and cycle requirements fall within the substitute part's specifications before implementation.

Q: What are the key differences between these two connectors?

A: The primary differences are electrical ratings and durability specifications. USB-A-S-RA-SMT-HD-T/R provides 2A current capacity and 5000 mating cycles, while 629104151021 provides 1.5A current capacity and 1500 mating cycles. Both connectors are mechanically and functionally identical for USB 2.0 applications.

Q: Are both parts suitable for high-temperature applications?

A: Operating temperature ranges are not specified for the USB-A-S-RA-SMT-HD-T/R. The 629104151021 operates from -40°C to 85°C. Confirm temperature requirements with your application specifications before part selection.

Q: Do these connectors require different PCB footprints?

A: No. Both connectors share identical mounting type (Surface Mount, Right Angle; Through Hole), mounting feature (Horizontal), and termination method (Solder). PCB footprints and assembly processes are compatible.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both USB-A-S-RA-SMT-HD-T/R and 629104151021 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement in regulated markets.
