Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1734081-2 be directly replaced with any of these substitute parts?

A: Direct replacement depends on application requirements. Tier 1 equivalents (Würth Elektronik 61400416021 and Kycon KUSBEX series) provide complete functional and electrical compatibility. Tier 2 and Tier 3 substitutes require verification of specific application parameters, particularly current requirements and EMI shielding necessity.

Q: What is the primary difference between the Kycon KUSBEX variants?

A: All Kycon KUSBEX variants (KUSBEX-ASFS1N-B, KUSBEX-ASFS1N-B30, KUSBEX-ASFS1N-W, KUSBEX-ASFS1N-W30) maintain identical electrical and mechanical specifications. Variants differ only in insulation color: black (B and B30 designations) or white (W and W30 designations). The "30" suffix indicates a specific packaging or configuration variant. Selection should be based on visual identification requirements or design specifications.

Q: Why is the Mercury United Electronics 690-004-221-013 listed as a substitute if it is unshielded?

A: The 690-004-221-013 is included as a functional equivalent for applications where EMI shielding is not a design requirement. The unshielded construction represents a significant deviation from the original shielded design. This part should be selected only when electromagnetic interference protection is not necessary for the application.

Q: What does "Tier 1 - Full Parametric Equivalent" mean?

A: Tier 1 classification indicates that the substitute part matches all specified electrical parameters (current rating, voltage rating, mating cycles), mechanical parameters (mounting type, termination method, connector type), and environmental specifications (operating temperature, moisture sensitivity) of the original TE Connectivity 1-1734081-2. These parts are direct functional replacements without performance compromises.

Q: Are all substitute parts ROHS compliant?

A: Yes. All listed substitute parts are either ROHS3 compliant or ROHS compliant, meeting current regulatory requirements for hazardous substance restrictions. The original TE Connectivity 1-1734081-2 has ROHS status listed as "Not applicable," indicating it predates current compliance requirements. All active substitutes meet modern regulatory standards.

Q: How do I determine if a Tier 2 or Tier 3 substitute is suitable for my application?

A: Evaluate the specific parameter deviations against your application requirements. For Tier 2 parts with reduced current ratings (1.0A vs. 1.5A), verify that your application current draw does not exceed the substitute's rating. For Tier 3 parts with unspecified parameters, contact the manufacturer to obtain complete electrical specifications before design integration.

Q: What is the significance of the 1500 mating cycle specification?

A: The 1500 mating cycle rating indicates the connector is rated for 1500 insertion and withdrawal cycles before performance degradation. This specification is relevant for applications involving frequent connection and disconnection. All Tier 1 and most Tier 2 substitutes maintain this specification, ensuring equivalent service life expectations.

Q: Can I use the Amphenol ICC UE27AC54100 if my application requires 1.5A current?

A: The UE27AC54100 is rated for 1.0A per contact, which is lower than the original 1.5A specification. Use of this part in applications requiring 1.5A operation would exceed the component's rated capacity and is not recommended. Select a Tier 1 equivalent or verify that your actual application current draw does not exceed 1.0A.

Q: What packaging options are available for these substitute parts?

A: Packaging varies by manufacturer. Würth Elektronik 61400416021 is supplied in Tray packaging. Kycon KUSBEX series parts are supplied in Tray packaging. Allied Components AUSB1-4600 is supplied in Tray packaging. Mercury United Electronics 690-004-221-013 is supplied in Bulk packaging. Stewart Connector SS-52100-001 is supplied in Tray packaging. Amphenol ICC UE27AC54100 is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Is the insulation color difference between Kycon variants functionally significant?

A: Insulation color (black vs. white) is a visual identification feature only and does not affect electrical or mechanical performance. Selection should be based on design documentation, assembly process requirements, or visual identification standards specific to your application or organization.
