Substitute Part Grouping Explanation
Substitute parts for the KUSBX-SLAS1N9-B are classified into two functional groups based on mounting configuration and electrical characteristics:
Group 1: Right-Angle Mounted Receptacles (Direct Mechanical Equivalents) These parts maintain the through-hole, right-angle mounting configuration with vertical flag orientation identical to the main part. Substitutes in this group include Molex 0484040003 and Amphenol ICC parts GSB3116342DHR, GSB3116344KHHR, GSB3116346FHR, GSB31D12021HHR, GSB31D13001HHR, and GSB31D13021HHR. All maintain 9-position USB Type-A receptacle architecture with shielded construction and gold-plated contacts.
Group 2: Vertical Mounted Receptacles (Functional Equivalents with Different Mounting) These parts provide USB 3.2 Gen 1 receptacle functionality with vertical (non-right-angle) through-hole mounting. Substitutes in this group include Amphenol ICC parts GSB3121171CHR, GSB312137CHR, and GSB31213R1C5HR. These are functionally equivalent but require different circuit board layout considerations due to vertical mounting orientation.
Substitution eligibility is determined by the following parameters:
- USB 3.2 Gen 1 (USB 3.1 Gen 1, Superspeed USB 3.0) specification compliance
- 9-position receptacle configuration
- Shielded construction with gold contact finish
- Through-hole solder termination
- Operating temperature range compatibility (-55°C to 85°C minimum)
- RoHS3 compliance or equivalent environmental certification

Engineering Selection Recommendations
For Direct Mechanical and Electrical Equivalence (Right-Angle Mounted)
The Molex 0484040003 provides full parametric equivalence with identical mounting configuration (through-hole, right-angle, vertical flag). This part maintains the same current rating (0.25A, 1.8A), voltage specification (30VAC/DC), and operating temperature range (-20°C to 85°C minimum). The Molex part features enhanced mating cycle durability (5000 cycles versus 1500 cycles) and includes board lock functionality. RoHS3 compliance is confirmed. The material flammability rating differs (UL94 HB versus UL94 V-0), which may be relevant for applications requiring higher flame resistance specifications.
The Amphenol ICC GSB3116342DHR, GSB3116344KHHR, and GSB3116346FHR maintain identical mounting configuration with extended mating cycle ratings (5000 cycles). These parts operate across the full temperature range (-55°C to 85°C) and carry UL94 V-0 flammability certification. Current rating specification is limited to 1.8A. GSB3116346FHR carries ROHS3 compliance certification, while GSB3116342DHR and GSB3116344KHHR carry RoHS compliance. All three are suitable for applications requiring right-angle mounting with enhanced durability.
The Amphenol ICC GSB31D12021HHR, GSB31D13001HHR, and GSB31D13021HHR maintain the right-angle mounting configuration with vertical flag orientation. These parts operate across the full temperature range (-55°C to 85°C) and carry UL94 V-0 flammability certification with ROHS3 compliance. Mating cycle rating is 1500 cycles, matching the main part specification. Current rating is not specified for these variants.
For Functional Equivalence with Vertical Mounting (Non-Right-Angle)
The Amphenol ICC GSB3121171CHR and GSB312137CHR provide USB 3.2 Gen 1 receptacle functionality with vertical (non-right-angle) through-hole mounting. These parts operate across the full temperature range (-55°C to 85°C) with UL94 V-0 flammability certification and ROHS3 compliance. Mating cycle rating is 1500 cycles. These parts include board lock features and are suitable for applications where vertical mounting orientation is acceptable or preferred. Current rating is not specified.
The Amphenol ICC GSB31213R1C5HR provides vertical mounting with enhanced mating cycle durability (5000 cycles) and specified current rating (1.8A). This part operates across the full temperature range (-55°C to 85°C) with UL94 V-0 flammability certification and RoHS compliance. This variant is suitable for applications requiring vertical mounting with higher durability specifications.
Compliance and Certification Considerations
All substitute parts maintain RoHS compliance (ROHS3 or equivalent). All parts are classified as active products with unlimited moisture sensitivity level (MSL 1). All parts feature shielded construction with gold-plated contacts and steel/stainless steel shell materials, consistent with the main part specification. Selection should be based on specific mounting configuration requirements (right-angle versus vertical) and durability needs (mating cycle rating).
Frequently Asked Questions (FAQ)
Q: Can the Molex 0484040003 be used as a direct replacement for the KUSBX-SLAS1N9-B?
A: The Molex 0484040003 is mechanically and electrically compatible for right-angle mounting applications. Both parts feature identical 9-position USB Type-A receptacle configuration, through-hole right-angle mounting with vertical flag orientation, and matching current/voltage ratings. The Molex part operates across a narrower temperature range (-20°C to 85°C versus -55°C to 85°C) and features UL94 HB flammability rating instead of UL94 V-0. Selection depends on specific temperature and flame resistance requirements.
Q: What is the difference between right-angle mounted and vertical mounted USB Type-A receptacles?
A: Right-angle mounted receptacles (such as KUSBX-SLAS1N9-B, Molex 0484040003, and Amphenol GSB3116 series) position the connector perpendicular to the circuit board surface with a flag-style mounting feature. Vertical mounted receptacles (such as Amphenol GSB3121 and GSB31D1 series) position the connector parallel to the circuit board surface. The choice between these configurations depends on circuit board layout, available space, and cable routing requirements. These two mounting styles are not interchangeable without circuit board redesign.
Q: Are all substitute parts RoHS compliant?
A: All substitute parts listed carry RoHS compliance certification. The main part (KUSBX-SLAS1N9-B) and most substitutes carry ROHS3 compliance. Some Amphenol ICC variants (GSB3116342DHR and GSB3116344KHHR) carry RoHS compliance without specific ROHS3 designation. All parts meet environmental compliance requirements for standard applications.
Q: What is the significance of mating cycle ratings?
A: Mating cycle rating indicates the number of times a connector can be mated and unmated before performance degradation. The KUSBX-SLAS1N9-B specifies 1500 mating cycles. Substitute parts with higher mating cycle ratings (such as Molex 0484040003 and Amphenol GSB3116 series at 5000 cycles) provide extended durability for applications requiring frequent connection/disconnection. Selection should be based on expected connector usage frequency.
Q: Can I substitute a vertical mounted connector for a right-angle mounted connector?
A: Vertical and right-angle mounted connectors are not interchangeable without circuit board redesign. The mounting orientation, hole pattern, and flag positioning differ significantly. Vertical mounted connectors (GSB3121 and GSB31213R1C5HR series) require different circuit board layout and cannot be directly substituted for right-angle mounted connectors (KUSBX-SLAS1N9-B, Molex 0484040003, GSB3116 series) without physical modification to the circuit board.
Q: What is the difference between UL94 V-0 and UL94 HB flammability ratings?
A: UL94 V-0 represents a higher flame resistance classification than UL94 HB. UL94 V-0 rated materials self-extinguish within 10 seconds after flame removal and do not produce flaming drips. UL94 HB rated materials are less stringent and may continue burning or produce drips. For applications requiring higher flame resistance (such as aerospace, medical, or safety-critical equipment), UL94 V-0 certification is preferred. The KUSBX-SLAS1N9-B carries UL94 V-0 certification; the Molex 0484040003 carries UL94 HB certification.
Q: Are there inventory considerations when selecting substitute parts?
A: Inventory availability varies among substitute parts. The KUSBX-SLAS1N9-B has 1023 pieces in stock. Molex 0484040003 has 12,294 pieces available. Amphenol ICC variants range from 925 to 7,111 pieces in stock. Inventory levels may influence selection for time-sensitive applications or high-volume production requirements.
Q: What current ratings should I consider for my application?
A: The KUSBX-SLAS1N9-B specifies dual current ratings of 0.25A and 1.8A. Most Amphenol ICC right-angle mounted substitutes (GSB3116 series) specify 1.8A current rating. Some Amphenol ICC variants do not specify current rating in available documentation. For applications requiring specific current handling capacity, verify that the selected substitute part meets or exceeds the required current specification. The Molex 0484040003 matches the dual current rating specification (0.25A, 1.8A).
