Parameter Comparison

Engineering Selection Recommendations

KUSBX-SMT2AP1S-B30TR (Kycon, Inc.): This substitute maintains identical electrical and mechanical specifications to the main part, with the primary difference being insulation color (Black vs. White). Both parts are manufactured by Kycon, Inc., share the same series designation (KUSBX-SMT), and carry equivalent RoHS3 compliance. This part is suitable for direct replacement in applications where insulation color does not affect functional requirements. Higher inventory availability (7870 pcs) supports supply chain continuity.

1-1734028-1 (TE Connectivity AMP Connectors): This substitute meets core USB-A plug connector requirements with equivalent mounting configuration and shielding. The part features higher current rating (1.5A vs. 1A) and specified mating cycle rating (1500 cycles), providing enhanced durability in high-cycle applications. Operating temperature range (0°C ~ 50°C) is narrower than the main part (-55°C ~ 85°C), limiting use in extended temperature environments. Voltage rating is specified as 30VDC rather than 30VAC. This part is suitable for applications operating within the specified temperature range where the enhanced current capacity and cycle rating provide operational advantages.

Frequently Asked Questions (FAQ)

Q: Can KUSBX-SMT2AP1S-B30TR be used as a direct replacement for KUSBX-SMT2AP1SWTR? A: Yes. Both parts are identical in electrical and mechanical specifications, including connector type, contact count, mounting configuration, current rating, voltage rating, shielding, and flammability rating. The only difference is insulation color (Black vs. White). Direct substitution is valid unless color specification is a design requirement.

Q: What are the limitations of using 1-1734028-1 as a substitute? A: The 1-1734028-1 has a narrower operating temperature range (0°C ~ 50°C) compared to the main part (-55°C ~ 85°C). This part is not suitable for applications requiring operation below 0°C or above 50°C. Additionally, voltage rating is specified as 30VDC rather than 30VAC. Use this substitute only in applications operating within the specified temperature and voltage parameters.

Q: Are all substitute parts RoHS compliant? A: Yes. The main part carries RoHS Compliance status, while both substitutes carry ROHS3 Compliance status. All three parts meet RoHS requirements for hazardous substance restrictions.

Q: What is the difference in packaging between these parts? A: KUSBX-SMT2AP1SWTR and KUSBX-SMT2AP1S-B30TR are supplied in Tape & Reel (TR) packaging. The 1-1734028-1 is supplied in Cut Tape (CT) packaging. Packaging selection depends on assembly process requirements and volume handling procedures.

Q: Does the higher current rating of 1-1734028-1 affect compatibility? A: No. The 1.5A rating of 1-1734028-1 exceeds the 1A requirement of the main part, providing additional current capacity margin. This does not create compatibility issues; the part can safely handle applications rated for 1A.

Q: Can these parts be used interchangeably in all applications? A: Substitution is valid only when all applicable parameters align with application requirements. The 1-1734028-1 substitute must not be used in applications requiring operation outside the 0°C ~ 50°C temperature range. KUSBX-SMT2AP1S-B30TR can be used interchangeably with the main part in all applications where insulation color is not a specification requirement.
