Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KUSBX-AP-KIT-SC is determined by the following critical parameters:

• Connector Type & Gender: Must be USB-A plug to maintain mechanical and electrical compatibility
• Number of Contacts: Must be 4 positions for signal and power pin alignment
• Mounting Type & Termination: Must be free hanging (in-line) with solder cup termination for identical PCB integration
• Current & Voltage Ratings: Must meet or exceed 1.5A at 30VAC minimum specifications
• Shielding & Contact Finish: Must maintain shielded construction with gold plating for signal integrity and corrosion resistance
• Compliance & Certifications: Must maintain UL94 V-0 flammability rating and RoHS compliance

The KUSBX-AP-KIT-SC-1 qualifies as a direct substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The KUSBX-AP-KIT-SC-1 is the qualified substitute for the obsolete KUSBX-AP-KIT-SC. Both components maintain identical electrical and mechanical specifications for the critical parameters governing USB-A plug connector substitution: connector type, contact count, mounting configuration, termination method, current and voltage ratings, shielding, and contact finish.

The KUSBX-AP-KIT-SC-1 offers an extended operating temperature range (-55°C ~ 105°C versus -55°C ~ 85°C) and expanded voltage rating specification (30VAC/DC versus 30VAC), providing enhanced performance margins. Both components maintain UL94 V-0 flammability certification and RoHS compliance, ensuring regulatory and safety standard continuity.

The KUSBX-AP-KIT-SC-1 is currently in active production status, ensuring long-term component availability for new designs, production builds, and field service applications.

Frequently Asked Questions (FAQ)

Q: Can the KUSBX-AP-KIT-SC-1 be used as a direct replacement for the KUSBX-AP-KIT-SC?

A: Yes. Both connectors share identical connector type (USB-A plug), contact configuration (4 positions), mounting method (free hanging in-line), termination style (solder cup), current rating (1.5A), and contact finish (gold plating). Mechanical and electrical compatibility is maintained for PCB integration and signal transmission.

Q: What are the key differences between these two parts?

A: The KUSBX-AP-KIT-SC-1 provides an extended operating temperature range (105°C maximum versus 85°C) and dual voltage rating specification (30VAC/DC versus 30VAC). The substitute part is in active production status, whereas the original part is obsolete.

Q: Are there any compliance or certification differences?

A: No. Both components maintain identical UL94 V-0 flammability rating and RoHS compliance status. Regulatory and safety certifications are equivalent.

Q: Does the extended temperature range of the KUSBX-AP-KIT-SC-1 affect compatibility?

A: No. Extended operating temperature range represents an enhancement that maintains backward compatibility. Applications operating within the original -55°C ~ 85°C range will function identically with the substitute part.

Q: What is the inventory status for these components?

A: The KUSBX-AP-KIT-SC (obsolete) has 1,243 pieces in stock. The KUSBX-AP-KIT-SC-1 (active) has 879 pieces in stock. For long-term production requirements, the active substitute part is recommended.
