Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0484040004 is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

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

Secondary Compatibility Parameters:

• Current Rating: 0.25A, 1.8A
• Voltage Rating: 30VAC/DC
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed meet these criteria. Variations in operating temperature range, mating cycles, shell material composition, and flammability rating are noted but do not disqualify substitution when the primary and secondary parameters align.

Parameter Comparison

Engineering Selection Recommendations

Molex 0484040003 is the primary substitute for the obsolete Molex 0484040004. Both parts share identical electrical and mechanical specifications, including current rating, voltage rating, mating cycles, and operating temperature range. The 0484040003 is active in production with higher inventory availability (12,294 units) and is packaged in trays for standard procurement workflows.

Kycon KUSBX-SLAS1N9-B and KUSBX-SLAS1N9-B15 are parametric equivalents suitable for applications where extended operating temperature range (-55°C ~ 85°C) is required. Both Kycon parts meet all primary equivalence criteria. The reduced mating cycle rating (1500 versus 5000) should be evaluated against application duty cycle requirements. Both parts carry ROHS3 compliance and UL94 V-0 flammability rating.

Stewart Connector SS-52000-002 meets all primary equivalence criteria and is available in high volume (51,368 units). This part features board lock functionality identical to the Molex 0484040004. Electrical specifications (current rating, voltage rating, mating cycles) are not specified in available documentation and should be confirmed with the manufacturer before selection for applications with specific electrical performance requirements.

All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, ensuring compatibility with standard PCB assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0484040003 be used as a direct replacement for the obsolete Molex 0484040004?

A: Yes. The 0484040003 is a parametric equivalent with identical specifications across all critical parameters: USB 3.2 Gen 1 compliance, 9-position receptacle configuration, through-hole right-angle mounting with vertical flag, solder termination, gold-plated contacts, 0.25A/1.8A current rating, 30VAC/DC voltage rating, 5000 mating cycles, and -20°C ~ 85°C operating temperature range. The primary difference is product status (active versus obsolete) and packaging format (tray).

Q: What is the difference between the Kycon KUSBX-SLAS1N9-B and KUSBX-SLAS1N9-B15?

A: Both Kycon parts are parametrically equivalent with identical electrical and mechanical specifications. The primary distinction is the suffix designation (-B versus -B15), which typically indicates internal design or manufacturing revision. Both parts meet the same USB 3.2 Gen 1 specification, support 9-position receptacle configuration, and feature vertical flag mounting. Inventory levels differ slightly (1,023 units for -B; 1,008 units for -B15).

Q: Are there differences in operating temperature range between substitute options?

A: Yes. The Molex 0484040004 and 0484040003 operate across -20°C ~ 85°C. The Kycon KUSBX-SLAS1N9-B and KUSBX-SLAS1N9-B15 extend the lower temperature limit to -55°C ~ 85°C. For applications requiring operation below -20°C, Kycon parts are the appropriate selection. For standard commercial temperature ranges, both options are suitable.

Q: What is the significance of mating cycle ratings?

A: Mating cycles indicate the number of connect/disconnect operations a connector is rated to withstand. The Molex 0484040004 and 0484040003 are rated for 5000 cycles. The Kycon KUSBX-SLAS1N9-B and KUSBX-SLAS1N9-B15 are rated for 1500 cycles. For applications with frequent mating/unmating operations, the Molex parts provide higher cycle endurance. For fixed installations with minimal connector cycling, Kycon parts are acceptable.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting EU Directive 2011/65/EU requirements for restricted hazardous substances. All parts also carry MSL 1 (Unlimited) moisture sensitivity classification, indicating no special moisture control measures are required during storage or assembly.

Q: What packaging formats are available?

A: The Molex 0484040004 (obsolete) was supplied in standard packaging. The Molex 0484040003, Kycon KUSBX-SLAS1N9-B, Kycon KUSBX-SLAS1N9-B15, and Stewart Connector SS-52000-002 are all available in tray packaging, suitable for automated pick-and-place assembly workflows.

Q: Can the Stewart Connector SS-52000-002 be used without confirming electrical specifications?

A: The SS-52000-002 meets all primary mechanical and functional equivalence criteria. However, current rating, voltage rating, and mating cycle specifications are not provided in available documentation. For applications with specific electrical performance requirements, confirmation of these parameters with Stewart Connector is recommended before final design selection.
