Substitute Part Grouping Explanation

Substitute parts for the A-USB A-LP-SMT are identified based on strict parametric equivalence across the following critical parameters:

Electrical Compatibility:

• Connector Type: USB-A (USB TYPE-A)
• Specifications: USB 2.0
• Number of Contacts: 4 positions
• Current Rating: 1.5A
• Mating Cycles: 1500

Mechanical Compatibility:

• Gender: Plug
• Mounting Type: Surface Mount, Right Angle; Through Hole
• Mounting Feature: Horizontal
• Termination: Solder

Physical & Material Specifications:

• Shielding: Shielded
• Contact Finish: Gold
• Shell/Shielding Material: Steel (SPCC)
• Material Flammability Rating: UL94 V-0

Regulatory Compliance:

Substitute parts TE Connectivity AMP Connectors 1734028-1 and Adam Tech USB-AP-S-RA-SMT meet all critical electrical and mechanical parameters. Variations in operating temperature range and voltage rating do not affect substitution eligibility, as these parameters represent design margins rather than functional requirements for the connector interface itself.

Parameter Comparison

Engineering Selection Recommendations

All three components—A-USB A-LP-SMT (Assmann WSW Components), 1734028-1 (TE Connectivity AMP Connectors), and USB-AP-S-RA-SMT (Adam Tech)—are active products with equivalent electrical and mechanical specifications for USB 2.0 Type-A plug connector applications.

Compliance & Certification: All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution. All components feature UL94 V-0 material flammability ratings, suitable for applications requiring flame-retardant properties.

Parametric Equivalence: The three parts are functionally interchangeable based on identical connector type, contact configuration, current rating, mating cycle specification, shielding design, and termination method. Gold-plated contacts and steel shielding provide consistent electrical performance and environmental protection across all three options.

Component Availability: Selection among these three parts may be based on supply chain availability, inventory levels, or procurement lead times. TE Connectivity 1734028-1 maintains 2141 pieces in stock, Adam Tech USB-AP-S-RA-SMT maintains 9545 pieces in stock, and Assmann WSW A-USB A-LP-SMT maintains 840 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1734028-1 be used as a direct replacement for the Assmann WSW A-USB A-LP-SMT?

A: Yes. Both components share identical connector type (USB-A), contact count (4), gender (plug), specifications (USB 2.0), mounting configuration (surface mount, right angle, through hole), current rating (1.5A), mating cycles (1500), shielding design (shielded), contact finish (gold), shell material (steel SPCC), and flammability rating (UL94 V-0). Both are ROHS3 compliant and REACH unaffected.

Q: What is the difference between the Adam Tech USB-AP-S-RA-SMT and the Assmann WSW A-USB A-LP-SMT?

A: The Adam Tech USB-AP-S-RA-SMT and Assmann WSW A-USB A-LP-SMT are electrically and mechanically equivalent across all critical parameters: connector type, contact configuration, current rating, shielding, contact finish, shell material, and flammability rating. The Adam Tech part does not specify mating cycle count in the provided data. Both are active products with ROHS3 compliance and REACH unaffected status.

Q: Are there any temperature range limitations when substituting these parts?

A: The Assmann WSW A-USB A-LP-SMT operates across -55°C to 85°C, the TE Connectivity 1734028-1 operates across 0°C to 50°C, and the Adam Tech USB-AP-S-RA-SMT operates across -20°C to 60°C. Operating temperature range represents the environmental specification for the connector housing and materials. Selection should be based on the application's actual operating environment. All three parts are suitable for standard commercial and industrial USB 2.0 applications within their respective temperature specifications.

Q: Do these connectors support the same voltage ratings?

A: The Assmann WSW A-USB A-LP-SMT does not specify a voltage rating. The TE Connectivity 1734028-1 is rated for 30VDC, and the Adam Tech USB-AP-S-RA-SMT is rated for 30VAC. USB 2.0 connectors operate at 5VDC per the USB specification, so all three parts are suitable for standard USB 2.0 applications. The specified voltage ratings represent the maximum dielectric withstand capability of the connector.

Q: Can these parts be used interchangeably in both surface mount and through-hole applications?

A: Yes. All three parts specify mounting type as "Surface Mount, Right Angle; Through Hole" with horizontal mounting feature and solder termination. They are designed for dual-mount capability and can be used interchangeably in applications requiring either surface mount or through-hole assembly methods.

Q: What is the significance of the gold contact finish across all three parts?

A: Gold plating on contacts provides corrosion resistance, improved electrical conductivity, and enhanced contact reliability over extended mating cycles. All three parts feature gold contact finish, ensuring consistent electrical performance and durability across 1500 mating cycles (or unspecified cycles for the Adam Tech part).

Q: Are all three parts suitable for shielded applications?

A: Yes. All three parts are specified as shielded connectors with steel (SPCC) shell/shielding material. Shielding provides electromagnetic interference (EMI) protection and is standard for USB 2.0 connectors in applications requiring signal integrity and noise immunity.
