Engineering Selection Recommendations

A-USB A-LP-SMT (Assmann WSW Components) is the manufacturer-recommended substitute. This part maintains identical mechanical and electrical specifications to the main part while offering the advantage of active product status and higher inventory availability (840 pcs). The upgrade to USB 2.0 specification provides forward compatibility while maintaining full backward compatibility with USB 1.1 applications. Packaging is supplied in Tray format. This substitute is preferred for new production and replacement applications where Assmann WSW Components sourcing is established.

1001-011-01101 (CNC Tech) is a direct functional equivalent with active product status and superior inventory availability (4347 pcs). This part maintains USB 1.1 specification matching and identical mechanical configuration. The operating temperature range extends to -40°C to 105°C, providing broader thermal envelope coverage. Voltage rating of 30V is specified. This substitute is suitable for applications requiring extended temperature performance or where CNC Tech component sourcing is preferred. Packaging is supplied in Tray format.

Both substitutes satisfy all primary compatibility criteria and carry ROHS3 compliance and UL94 V-0 flammability certification matching the original part.

Frequently Asked Questions (FAQ)

Q: Can A-USB A-LP-SMT replace A-USB A-LP-SMT-R in existing designs?

A: Yes. Both parts share identical connector type, contact count, gender, mounting configuration, termination method, current rating, and flammability certification. The A-USB A-LP-SMT offers USB 2.0 specification, which is backward compatible with USB 1.1 applications. Physical and electrical compatibility is maintained.

Q: What is the difference between A-USB A-LP-SMT and 1001-011-01101?

A: Both are functionally equivalent USB-A plug connectors with 4 contacts, solder termination, and 1.5A current rating. Key differences are manufacturer (Assmann WSW Components vs. CNC Tech), USB specification (USB 2.0 vs. USB 1.1), operating temperature range (-55°C to 85°C vs. -40°C to 105°C), and inventory availability. Selection depends on sourcing preference and thermal requirements.

Q: Are these substitutes suitable for USB 1.1 applications?

A: Yes. The 1001-011-01101 maintains USB 1.1 specification. The A-USB A-LP-SMT operates at USB 2.0 specification but is fully backward compatible with USB 1.1 designs. Both parts meet the electrical and mechanical requirements of the original A-USB A-LP-SMT-R.

Q: What packaging formats are available for these substitutes?

A: A-USB A-LP-SMT is supplied in Tray packaging. 1001-011-01101 is supplied in Tray packaging. Both formats are standard for surface mount component distribution.

Q: Are all three parts RoHS3 compliant?

A: Yes. The main part A-USB A-LP-SMT-R and both substitutes (A-USB A-LP-SMT and 1001-011-01101) are ROHS3 compliant and carry UL94 V-0 material flammability certification.
