Frequently Asked Questions (FAQ)
Q: Can USB-B-S-S-W-VT-R be directly replaced with USB-B-S-S-B-VT?
A: Yes. Both parts are manufactured by Samtec Inc. with identical electrical specifications, mechanical form factors, and performance ratings. The only difference is insulation color (white versus black), which does not affect electrical or mechanical compatibility. Both are ROHS3 Compliant with MSL 1 (Unlimited).
Q: What is the significance of the operating temperature range difference between the main part (-50°C to 85°C) and most substitutes (-40°C to 85°C)?
A: The main part USB-B-S-S-W-VT-R operates 10°C lower at the minimum temperature. If your application requires operation below -40°C, only the main part, Würth Elektronik alternatives (to -40°C), or Kycon KUSBVX-AS1N-B (to -55°C) are suitable. For applications within -40°C to 85°C, all listed substitutes are acceptable.
Q: Are there differences in current handling capability among the substitutes?
A: Yes. The main part USB-B-S-S-W-VT-R does not specify a current rating. Molex 1050570001 and Würth Elektronik parts (614004135023, 6140041350231) are rated at 1.5A. TE Connectivity 1734366 series and Kycon KUSBVX-AS1N-B are rated at 1A. For applications requiring 1.5A continuous current, select Molex or Würth Elektronik alternatives.
Q: What shell material options are available among the substitutes?
A: The main part uses phosphor bronze. Substitutes employ phosphor bronze (Samtec alternatives), steel stainless (Molex 1050570001), brass (TE Connectivity 1734366 series, Würth Elektronik), or copper alloy (Kycon KUSBVX-AS1N-B). All materials provide equivalent shielding performance for USB 2.0 applications.
Q: Do all substitutes support the same number of mating cycles?
A: Most substitutes support 1500 mating cycles, matching the main part specification. Molex 1050570001 does not specify mating cycle data. For applications requiring documented 1500-cycle rating, avoid the Molex part.
Q: Which substitute offers the best inventory availability?
A: TE Connectivity 1734366-2 has the highest inventory at 58,505 units. Kycon KUSBVX-AS1N-B follows with 14,661 units. Samtec USB-B-S-S-B-VT has 4,166 units. For immediate procurement needs, these three options provide the strongest supply position.
Q: Are all substitutes RoHS and REACH compliant?
A: Most substitutes are ROHS3 Compliant with REACH Unaffected status. TE Connectivity 1734366-3 shows RoHS Compliant (not ROHS3) with Vendor Undefined REACH status. For applications requiring ROHS3 Compliance and confirmed REACH status, verify part-specific documentation or select alternatives with explicit ROHS3 and REACH Unaffected designations.
Q: Can insulation color be used as a selection criterion for substitution?
A: Insulation color is a visual identifier only and does not affect electrical or mechanical performance. Selection by color is permitted for design documentation, assembly traceability, or visual circuit board identification. All color variants (white, black, blue) within each manufacturer series are functionally equivalent.
