Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-1734346-3 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Connector Type: USB-B (USB TYPE-B)
• Specifications: USB 2.0
• Number of Contacts: 4
• Gender: Receptacle
• Mounting Type: Surface Mount, Right Angle
• Mounting Feature: Horizontal
• Termination: Solder
• Number of Ports: 1
• Voltage - Rated: 30VAC
• Mating Cycles: 1500
• Contact Finish: Gold
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters Permitting Substitution:

• Packaging Format (Tape & Reel, Cut Tape)
• Manufacturer (TE Connectivity, Samtec)
• Operating Temperature Range (within or exceeding specified limits)
• Insulation Color (Black, White)
• Shell/Shielding Material composition (Phosphor Bronze/Steel/Stainless vs. Steel)

All identified substitute parts maintain full electrical and mechanical compatibility with the primary part number while offering alternative packaging configurations and extended environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full compliance with ROHS3 and UL94 V-0 flammability requirements. Selection between substitute options is determined by specific application requirements:

1-1734346-1 (TE Connectivity): Identical electrical and thermal specifications to the primary part. Differs only in packaging format (Cut Tape vs. Tape & Reel). Selection is appropriate for applications with lower volume requirements or where Cut Tape packaging is preferred for automated assembly processes.

USB-B-S-F-B-SM-TR (Samtec): Extends operating temperature range to -50°C ~ 85°C, providing enhanced thermal performance for applications requiring operation beyond the primary part's 0°C ~ 50°C specification. Maintains Tape & Reel packaging. REACH Unaffected status applies.

USB-B-S-S-B-SM-TR (Samtec): Extends operating temperature range to -50°C ~ 85°C with identical packaging and configuration to USB-B-S-F-B-SM-TR. Differs only in shell/shielding material composition. REACH Unaffected status applies.

USB-B-S-S-W-SM-TR (Samtec): Extends operating temperature range to -50°C ~ 85°C with white insulation color instead of black. All other specifications remain equivalent. REACH Unaffected status applies.

All substitute parts are certified to ECCN EAR99 and HTSUS 8536.69.4040 classifications, matching the primary part's regulatory designation.

Frequently Asked Questions (FAQ)

Q: Can 1-1734346-1 be used as a direct replacement for 1-1734346-3?

A: Yes. Both parts are manufactured by TE Connectivity and maintain identical electrical specifications, thermal ratings, and mechanical configurations. The only difference is packaging format: 1-1734346-1 is supplied in Cut Tape (CT) format while 1-1734346-3 is supplied in Tape & Reel (TR) format. Selection depends on assembly equipment compatibility and volume requirements.

Q: What is the primary advantage of Samtec USB-B connector substitutes?

A: Samtec USB-B-S-F-B-SM-TR, USB-B-S-S-B-SM-TR, and USB-B-S-S-W-SM-TR all extend the operating temperature range to -50°C ~ 85°C compared to the primary part's 0°C ~ 50°C specification. This extended range is suitable for applications requiring operation in extreme thermal environments.

Q: Are there differences in shell material between TE Connectivity and Samtec options?

A: Yes. The primary TE Connectivity part (1-1734346-3) uses Phosphor Bronze, Steel, and Stainless materials for shell/shielding. Samtec substitutes use Steel exclusively. Both material compositions meet UL94 V-0 flammability requirements and maintain equivalent electrical performance.

Q: Does insulation color affect electrical performance?

A: No. USB-B-S-S-W-SM-TR differs from other Samtec options only in insulation color (white vs. black). Electrical specifications, contact finish, and performance characteristics remain identical. Color selection is determined by application aesthetics or assembly identification requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance status, matching the primary part's regulatory requirement.

Q: What is the significance of Moisture Sensitivity Level 1 (Unlimited)?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. The part can be stored indefinitely without desiccant packaging or environmental controls, simplifying inventory management and supply chain logistics.

Q: Can Samtec parts be used in applications originally designed for TE Connectivity connectors?

A: Yes, provided the application's operating temperature requirements do not exceed 0°C ~ 50°C. If extended temperature operation is required, Samtec substitutes with -50°C ~ 85°C ratings are appropriate. All other electrical and mechanical parameters are equivalent.

Q: What packaging format should be selected for high-volume automated assembly?

A: Tape & Reel (TR) format is standard for automated pick-and-place assembly. Both 1-1734346-3 and all Samtec substitutes are available in TR format. Cut Tape (CT) format (1-1734346-1) is suitable for lower-volume or manual assembly processes.
