Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0484050001 are qualified based on the following critical parameters that determine functional interchangeability:

Primary Matching Criteria:

• 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: Horizontal
• Termination: Solder
• Features: Board Lock
• Shielding: Shielded
• Contact Finish: Gold

Secondary Compatibility Parameters:

• Operating Temperature Range: -20°C to 85°C (or wider range)
• Current Rating: 0.25A minimum, 1.8A nominal
• Voltage Rating: 30VAC/DC minimum
• Mating Cycles: 5000 minimum
• RoHS Compliance: ROHS3 Compliant

All identified substitute parts match the primary criteria. Variations in secondary parameters (operating temperature, current rating, mating cycles, shell material) are noted in the comparison table below and do not prevent functional substitution when application requirements are within the specified ranges.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes (Active Status, Full Compliance):

Molex 0484050003 and Molex 0484050004 are direct parametric equivalents within the same manufacturer series (48405). Both parts maintain identical electrical and mechanical specifications to the primary part number 0484050001, with higher inventory availability (28,732 and 24,079 units respectively). Both are ROHS3 compliant and active products.

Amphenol ICC GSB311131HR (GSB3 series) provides full functional equivalence with matching core parameters. This part is RoHS compliant and active. Operating temperature range is not specified in available documentation.

Extended Compatibility (Active Status, Verified Compliance):

Stewart Connector SS-52000-001 offers extended operating temperature range (-55°C to 85°C) and UL94 V-0 flammability rating. Current rating and voltage specifications are not provided; application requirements must be verified against standard USB 3.0 specifications.

CUI Devices UJ3-AH-4-TH maintains core USB 3.0 specifications with UL94 V-0 flammability rating. Mating cycle rating is 1500 cycles (lower than primary part). Current rating is specified as 1A.

Adam Tech USB-A3-S-RA provides extended operating temperature range (-40°C to 85°C) with UL94 V-0 flammability rating and 1.8A current rating. Voltage and mating cycle specifications are not provided.

GCT USB1135-15-9-L-B offers enhanced durability with 20,000 mating cycles and 3A current rating capability. Operating temperature range extends to -55°C. This part is active and ROHS3 compliant.

Obsolete Status (Not Recommended for New Designs):

GCT USB1075-30-P-B is classified as obsolete. While parametric equivalence is confirmed, this part should not be selected for new circuit board designs or long-term production applications.

Frequently Asked Questions (FAQ)

Q: Can Molex 0484050003 or 0484050004 be used as direct replacements for 0484050001?

A: Yes. Both parts are parametric equivalents within the Molex 48405 series with identical electrical specifications, mechanical mounting, and connector interface. All three parts are ROHS3 compliant and active products. Selection between these three Molex variants depends on inventory availability and lead time requirements.

Q: What are the key differences between Molex and Amphenol ICC substitutes?

A: Molex 0484050001, 0484050003, and 0484050004 use stainless steel shell material, while Amphenol ICC GSB311131HR uses copper alloy. Both materials provide equivalent shielding performance for USB 3.0 applications. Amphenol ICC part is RoHS compliant (not specified as ROHS3). Operating temperature range for the Amphenol part is not documented.

Q: Are there performance differences between parts with 5000 mating cycles versus 20,000 mating cycles?

A: The GCT USB1135-15-9-L-B connector is rated for 20,000 mating cycles compared to 5000 cycles for the primary part. This indicates enhanced mechanical durability for high-cycle insertion/removal applications. Selection should be based on actual application duty cycle requirements. For standard applications with infrequent connector mating, the 5000-cycle rating is sufficient.

Q: Why is the GCT USB1075-30-P-B listed as obsolete?

A: Product status is classified as obsolete in manufacturer documentation. While electrical and mechanical specifications match the primary part, obsolete components face supply discontinuation risk and should not be selected for new designs or production applications requiring long-term component availability.

Q: Can I use a substitute part with a lower current rating?

A: Current rating specifications must meet or exceed application requirements. CUI Devices UJ3-AH-4-TH is rated for 1A, which is lower than the primary part's 1.8A rating. This part is suitable only for applications requiring 1A or less. For applications requiring the full 1.8A capability, select parts rated for 1.8A or higher (Molex variants, Amphenol ICC, Adam Tech, GCT USB1075, or GCT USB1135).

Q: What is the significance of UL94 V-0 flammability rating?

A: UL94 V-0 indicates superior flame resistance compared to UL94 HB (the primary part's rating). Parts with V-0 rating (Stewart Connector, CUI Devices, Adam Tech, GCT USB1135) provide enhanced safety in applications where flammability performance is a design requirement. The primary part's UL94 HB rating is standard for most commercial USB connector applications.

Q: Are all substitute parts ROHS3 compliant?

A: Most substitute parts are ROHS3 compliant. Amphenol ICC GSB311131HR is specified as RoHS compliant without the "3" designation. For applications requiring strict ROHS3 compliance, verify compliance status with the component supplier or select from Molex, Stewart Connector, CUI Devices, Adam Tech, or GCT parts explicitly marked ROHS3 compliant.

Q: Can I substitute based on shell material alone?

A: No. Shell material (stainless steel, copper alloy, or brass) affects mechanical properties and shielding characteristics but does not determine functional interchangeability. All substitute parts provide equivalent shielding performance for USB 3.0 applications. Shell material selection should be based on mechanical durability requirements and environmental conditions, not as a primary substitution criterion.
