Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the main part USB-A-S-F-W-VU-RC.

Samtec USB-A-S-F-B-VU is the direct parametric equivalent, differing only in insulation color (black). This part is recommended for applications where color specification is not a constraint and where Samtec supply chain continuity is preferred.

Molex 0482040001 provides cross-manufacturer substitution with extended operating temperature range (-55°C vs. -50°C) and specified current rating of 1.5A. This part is suitable for applications requiring broader temperature performance.

Molex 0673298000, 0673298001, 0673298020, 0673298021 (67329 series) maintain core USB 2.0 receptacle specifications with copper alloy shielding and 1A current rating. These parts are suitable for standard USB 2.0 applications where operating temperature and voltage specifications are not critical constraints.

Molex 0894858000, 0894858001, 0894858002, 0894858003 (89485 series) feature steel shielding, 750VAC voltage rating, and 1A per contact current rating with restricted operating temperature range (0°C ~ 50°C). These parts are applicable only to applications operating within the specified temperature window.

Selection should prioritize parts with operating temperature ranges that encompass the intended application environment and voltage ratings that meet or exceed system requirements.

Frequently Asked Questions (FAQ)

Q: Can USB-A-S-F-B-VU replace USB-A-S-F-W-VU-RC directly? A: Yes. Both parts are manufactured by Samtec Inc. and share identical electrical and mechanical specifications. The only difference is insulation color (black vs. white). Direct substitution is valid for applications where color is not specified.

Q: What are the key differences between Samtec and Molex substitutes? A: Samtec USB-A-S-F-B-VU is a direct equivalent from the same manufacturer. Molex substitutes maintain USB 2.0 specification, 4-position receptacle configuration, through-hole right-angle mounting, board lock, and shielded design. Variations include shell material (steel or copper alloy), current ratings, and operating temperature ranges.

Q: Are all Molex parts suitable for the same temperature range as USB-A-S-F-W-VU-RC? A: No. The main part operates from -50°C to 85°C. Molex 0482040001 extends to -55°C. Molex 0673298000, 0673298001, 0673298020, and 0673298021 do not specify operating temperature. Molex 0894858000, 0894858001, 0894858002, and 0894858003 are limited to 0°C ~ 50°C. Application temperature requirements must be verified before selection.

Q: What is the significance of the 1500 mating cycle rating? A: The USB-A-S-F-W-VU-RC is rated for 1500 mating cycles, indicating mechanical durability for connector insertion and removal cycles. Molex substitutes do not specify mating cycle ratings in the provided data. Applications requiring high-cycle reliability should prioritize parts with documented cycle ratings.

Q: Are all parts ROHS3 compliant? A: Yes. All listed parts, including the main part and all substitutes, are ROHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1).

Q: Can I use Molex 0894858000 series in applications requiring -50°C operation? A: No. The 0894858000 series is rated for 0°C ~ 50°C operation only. For applications requiring -50°C operation, use USB-A-S-F-W-VU-RC, USB-A-S-F-B-VU, or Molex 0482040001.

Q: What is the difference between 30VAC and 750VAC rated parts? A: The main part USB-A-S-F-W-VU-RC is rated for 30VAC. Molex 0894858000 series parts are rated for 750VAC, indicating higher voltage isolation capability. For standard USB 2.0 applications operating at 30VAC or below, both ratings are acceptable. Higher voltage ratings do not restrict use in lower voltage applications.
