Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the USB1075-30-P-B is determined by strict adherence to the following core parameters:

Critical Matching Parameters:

• Connector Type: USB-A (USB TYPE-A)
• Specifications: USB 3.2 Gen 1 (USB 3.1 Gen 1, Superspeed USB 3.0)
• Number of Contacts: 9
• Gender: Receptacle
• Mounting Type: Through Hole, Right Angle
• Mounting Feature: Horizontal
• Termination: Solder
• Features: Board Lock
• Shielding: Shielded
• Contact Finish: Gold

All identified substitute parts match these critical parameters. Variations in secondary parameters such as operating temperature range, current rating, voltage rating, mating cycles, shell material, and flammability rating are documented in the comparison table below. These variations must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain functional equivalence to the USB1075-30-P-B across critical connector parameters: USB-A receptacle configuration, USB 3.2 Gen 1 specification, 9-position contact arrangement, through-hole right-angle mounting, solder termination, board lock feature, shielding, and gold contact finish.

Primary Recommendation: USB1135-15-9-L-B (GCT) offers the most direct substitution path. As an active GCT product from the same manufacturer family, it maintains identical core specifications while providing enhanced durability with 20,000 mating cycles versus 5,000 on the original part. Operating temperature range matches the original (-55°C ~ 85°C), and ROHS3 compliance is maintained.

Secondary Recommendations: Molex 0484050001, 0484050003, and 0484050004 provide functionally equivalent alternatives with active product status and ROHS3 compliance. These parts operate within -20°C ~ 85°C temperature range and maintain 5,000 mating cycle ratings. Material flammability rating is UL94 HB rather than V-0.

Alternative Options: SS-52000-001 (Stewart Connector) and USB-A3-S-RA (Adam Tech) maintain UL94 V-0 flammability ratings and ROHS3 compliance. GSB311131HR (Amphenol ICC) and UJ3-AH-4-TH (CUI Devices) are active alternatives with RoHS compliance, though operating temperature and mating cycle specifications differ from the original.

Selection should prioritize product status (all substitutes are active), regulatory compliance (ROHS3 or RoHS compliant), and application-specific requirements for operating temperature range, current capacity, and mating cycle endurance.

Frequently Asked Questions (FAQ)

Q: Can USB1135-15-9-L-B directly replace USB1075-30-P-B in existing designs?

A: Yes. Both connectors share identical connector type, USB 3.2 Gen 1 specification, 9-position contact configuration, through-hole right-angle mounting, horizontal orientation, solder termination, board lock feature, shielding, and gold contact finish. The USB1135-15-9-L-B is rated for 20,000 mating cycles compared to 5,000 on the original, providing enhanced reliability. Operating temperature range is identical at -55°C ~ 85°C.

Q: What are the key differences between Molex alternatives (0484050001, 0484050003, 0484050004) and the original GCT part?

A: Molex alternatives maintain functional equivalence across all critical connector parameters. Primary differences include: operating temperature range of -20°C ~ 85°C (versus -55°C ~ 85°C on original), voltage rating of 30VAC/DC (versus 100V), and material flammability rating of UL94 HB (versus UL94 V-0). Current rating and mating cycles match the original specification.

Q: Are there differences in shell material among substitute options?

A: Yes. The original USB1075-30-P-B uses copper alloy shell material. Substitutes vary: USB1135-15-9-L-B uses steel (SUS304), Molex parts use stainless steel, GSB311131HR and SS-52000-001 use copper alloy, and UJ3-AH-4-TH uses brass. All maintain shielding and gold contact finish. Shell material selection should align with application environmental and mechanical requirements.

Q: Which substitute part offers the highest mating cycle rating?

A: USB1135-15-9-L-B (GCT) is rated for 20,000 mating cycles, compared to 5,000 cycles on the original USB1075-30-P-B and most other substitutes. UJ3-AH-4-TH (CUI Devices) is rated for 1,500 mating cycles, making it suitable only for lower-cycle-count applications.

Q: Do all substitute parts maintain ROHS3 compliance?

A: Most substitutes maintain ROHS3 compliance: USB1135-15-9-L-B, Molex parts (0484050001, 0484050003, 0484050004), SS-52000-001, UJ3-AH-4-TH, and USB-A3-S-RA. GSB311131HR (Amphenol ICC) carries RoHS compliance designation without specific ROHS3 notation. Regulatory requirements should be confirmed for specific applications.

Q: What is the inventory availability of substitute parts?

A: Current inventory levels are: USB1135-15-9-L-B (3,698 pcs), 0484050001 (684 pcs), 0484050003 (28,732 pcs), 0484050004 (24,079 pcs), GSB311131HR (17,464 pcs), SS-52000-001 (25,521 pcs), UJ3-AH-4-TH (1,460 pcs), and USB-A3-S-RA (5,667 pcs). Inventory levels should be confirmed at time of procurement.
