Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A-USB/2-A-LP-SMT are qualified based on strict alignment of core electrical and mechanical parameters. The substitution criteria include:

Primary Matching Parameters:

• Connector Type: USB-A (USB TYPE-A)
• Specifications: USB 2.0
• Number of Contacts: 4 positions
• Gender: Plug configuration
• Mounting Type: Surface Mount with Right Angle orientation and Through Hole capability
• Mounting Feature: Horizontal alignment
• Termination: Solder connection method
• Current Rating: 1.5A minimum
• Shielding: Shielded construction
• Contact Finish: Gold plating
• Shell/Shielding Material: Steel (SPCC)
• Material Flammability Rating: UL94 V-0
• Regulatory Compliance: ROHS3 Compliant and REACH Unaffected

Identified Substitute Parts:

• 1734028-1 (TE Connectivity AMP Connectors)
• USB-AP-S-RA-SMT (Adam Tech)

Both substitute parts satisfy all primary matching parameters and maintain equivalent functional and physical characteristics for direct component substitution.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and satisfy ROHS3 compliance and REACH unaffected regulatory requirements. Selection between the A-USB/2-A-LP-SMT and its substitutes depends on application-specific operating temperature requirements and voltage rating specifications.

The A-USB/2-A-LP-SMT (Assmann WSW Components) supports the widest operating temperature range of -55°C to 85°C, making it suitable for applications requiring extended temperature performance. The 1734028-1 (TE Connectivity AMP Connectors) operates within 0°C to 50°C and includes a specified 30VDC voltage rating. The USB-AP-S-RA-SMT (Adam Tech) operates within -20°C to 60°C with a 30VAC voltage rating.

All parts share identical core electrical and mechanical specifications including 1.5A current rating, 4-position configuration, gold contact finish, steel shielding material, and UL94 V-0 flammability rating. Mating cycle specification of 1500 cycles is confirmed for both the main part and the TE Connectivity substitute; the Adam Tech part does not specify mating cycles.

Frequently Asked Questions (FAQ)

Q: Can the 1734028-1 directly replace the A-USB/2-A-LP-SMT in all applications?

A: The 1734028-1 shares all core electrical and mechanical parameters with the A-USB/2-A-LP-SMT. However, the operating temperature range differs: 1734028-1 operates 0°C to 50°C versus A-USB/2-A-LP-SMT at -55°C to 85°C. Applications requiring operation below 0°C or above 50°C require the original part or alternative evaluation.

Q: What are the key differences between the USB-AP-S-RA-SMT and the original A-USB/2-A-LP-SMT?

A: The USB-AP-S-RA-SMT maintains equivalent connector type, contact configuration, mounting style, and current rating. Operating temperature range is -20°C to 60°C. The mating cycle specification is not provided for the Adam Tech part, whereas the original specifies 1500 cycles. Voltage rating is specified as 30VAC for the Adam Tech part.

Q: Are all three parts suitable for high-reliability applications?

A: All three parts are ROHS3 compliant, REACH unaffected, and feature UL94 V-0 flammability rating. The A-USB/2-A-LP-SMT and 1734028-1 both specify 1500 mating cycles. Selection for high-reliability applications should account for operating temperature requirements and mating cycle specifications.

Q: Do these connectors support the same current and voltage specifications?

A: All three parts support 1.5A current rating. Voltage specifications differ: the A-USB/2-A-LP-SMT does not specify voltage rating, the 1734028-1 specifies 30VDC, and the USB-AP-S-RA-SMT specifies 30VAC. Applications with specific voltage requirements should reference the appropriate part specification.

Q: What is the significance of the insulation color differences?

A: Insulation color variations (White for A-USB/2-A-LP-SMT, Natural for 1734028-1, Black for USB-AP-S-RA-SMT) are cosmetic and do not affect electrical or mechanical function. Color selection may be driven by manufacturing process or aesthetic requirements but does not impact substitution compatibility.

Q: Are there inventory considerations for these substitute parts?

A: Current inventory levels are: A-USB/2-A-LP-SMT (937 Pcs), 1734028-1 (2141 Pcs), and USB-AP-S-RA-SMT (9545 Pcs). Inventory status is subject to change and should be confirmed at time of procurement.
