Substitute Part Grouping Explanation

Substitute parts for the Molex 0484040001 are qualified based on strict parametric equivalence across the following critical parameters:

• Connector Type: USB-A (USB TYPE-A) receptacle
• Number of Contacts: 9 positions
• USB Specification: USB 3.2 Gen 1 (Superspeed USB 3.0)
• Mounting Type: Through Hole, Right Angle
• Mounting Feature: Vertical, Flag
• Termination: Solder
• Shielding: Shielded
• Contact Finish: Gold
• RoHS Compliance: ROHS3 Compliant

All listed substitutes meet these core electrical and mechanical parameters. Variations in operating temperature range, mating cycle ratings, shell material, and flammability ratings are noted in the comparison table below and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Molex 0484040003 is the primary substitute for the obsolete Molex 0484040001. Both parts are manufactured by Molex, share identical electrical and mechanical specifications, and maintain the same operating temperature range and mating cycle rating. The 0484040003 is currently in active production with higher inventory availability (12,294 units) compared to the original part (790 units). Both parts carry ROHS3 compliance and UL94 HB flammability rating.

Kycon KUSBX-SLAS1N9-B and KUSBX-SLAS1N9-B15 are parametrically equivalent alternatives from an active manufacturer. These parts maintain all critical USB 3.2 Gen 1 electrical specifications and mechanical mounting characteristics. Key differences include an extended operating temperature range (-55°C to 85°C versus -20°C to 85°C) and a reduced mating cycle rating (1,500 cycles versus 5,000 cycles). Both Kycon parts feature UL94 V-0 flammability rating, providing superior flame resistance compared to the original UL94 HB rating. These parts are suitable for applications requiring extended temperature performance or enhanced flammability compliance.

Stewart Connector SS-52000-002 maintains parametric equivalence for connector type, contact count, USB specification, mounting configuration, and shielding. This part features a copper alloy shell material and UL94 V-0 flammability rating. Electrical specifications (current rating, voltage rating, mating cycles) are not specified in available documentation and must be confirmed with the manufacturer before selection for applications with defined electrical performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0484040003 be used as a direct replacement for the Molex 0484040001?

A: Yes. Both parts are identical in electrical and mechanical specifications, including connector type, contact count, USB 3.2 Gen 1 rating, mounting type, current rating, voltage rating, and mating cycle performance. The primary difference is product status: 0484040001 is obsolete while 0484040003 is in active production.

Q: What are the key differences between Molex and Kycon substitute parts?

A: Molex 0484040003 maintains the original -20°C to 85°C operating temperature range and 5,000 mating cycle rating with UL94 HB flammability. Kycon KUSBX-SLAS1N9-B and KUSBX-SLAS1N9-B15 offer extended temperature operation (-55°C to 85°C) and superior flammability rating (UL94 V-0) but with reduced mating cycle rating (1,500 cycles). Select based on application temperature requirements and mechanical durability needs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts—Molex 0484040003, Kycon KUSBX-SLAS1N9-B, Kycon KUSBX-SLAS1N9-B15, and Stewart Connector SS-52000-002—are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the difference between the two Kycon part numbers?

A: KUSBX-SLAS1N9-B and KUSBX-SLAS1N9-B15 are functionally equivalent. Both share identical electrical specifications, operating temperature range, mating cycle rating, and flammability rating. The suffix "-B15" indicates a packaging or configuration variant. Confirm specific application requirements with Kycon documentation.

Q: Should I consider the Stewart Connector SS-52000-002 if electrical specifications are not fully documented?

A: The Stewart Connector SS-52000-002 is parametrically equivalent for all specified mechanical and connector characteristics. However, current rating, voltage rating, and mating cycle specifications are not provided in available data. Obtain complete electrical specifications from Stewart Connector before selecting this part for applications with defined electrical performance requirements.

Q: What packaging options are available for these substitute parts?

A: Molex 0484040003, Kycon KUSBX-SLAS1N9-B, Kycon KUSBX-SLAS1N9-B15, and Stewart Connector SS-52000-002 are all supplied in Tray packaging. The original Molex 0484040001 packaging type is not specified.
