Substitute Part Grouping Explanation

Substitution of the Molex 0483950003 is determined by strict equivalence across the following critical parameters:

• Connector Type & Gender: USB-A receptacle configuration
• Contact Count: 9 positions
• USB Specification: USB 3.2 Gen 1 (Superspeed USB 3.0) compliance
• Mounting Configuration: Board edge cutout with through-hole, right-angle orientation and horizontal, mid-mount reverse mounting feature
• Electrical Ratings: Current (0.25A, 1.8A) and voltage (30VAC/DC minimum)
• Mechanical Durability: 5000 mating cycles minimum
• Environmental & Compliance: Operating temperature -20°C to 85°C, UL94 V-0 flammability, ROHS3 compliance

The Würth Elektronik 692121130100 meets all these criteria and qualifies as a parametric equivalent substitute.

Engineering Selection Recommendations

The Würth Elektronik 692121130100 is the qualified substitute for the obsolete Molex 0483950003. Selection is based on:

• Product Status: The Molex part is obsolete; the Würth Elektronik equivalent is active and currently in production, ensuring long-term availability and supply chain continuity.
• Compliance Alignment: Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for equivalent applications.
• Electrical & Mechanical Equivalence: Identical USB 3.2 Gen 1 specification, contact configuration, current/voltage ratings, and mating cycle durability ensure functional interchangeability in existing designs.
• Packaging Consideration: The substitute is supplied in Tape & Reel format, which may require adjustment to procurement and assembly workflows compared to bulk packaging of the original part.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 692121130100 directly replace the Molex 0483950003 in existing designs?

A: Yes. Both connectors share identical electrical specifications (USB 3.2 Gen 1, 9-position receptacle, 0.25A/1.8A current rating, 30VAC/DC voltage), mechanical mounting configuration (board edge cutout, through-hole right-angle), and environmental ratings (-20°C to 85°C operating temperature, UL94 V-0 flammability). No design modification is required.

Q: What is the primary reason for substitution?

A: The Molex 0483950003 is classified as obsolete. The Würth Elektronik 692121130100 is an active product with current manufacturing support, ensuring reliable procurement and supply chain availability.

Q: Are there differences in shell or contact materials between these parts?

A: Yes. The Molex part uses steel/stainless steel shell material, while the Würth Elektronik substitute uses brass. Both materials are compatible with the specified gold contact finish and UL94 V-0 flammability rating. Material selection does not affect electrical or mechanical performance within the specified operating parameters.

Q: What packaging format does the substitute come in?

A: The Würth Elektronik 692121130100 is supplied in Tape & Reel (TR) format. If the original design used bulk packaging, procurement and assembly processes may require adjustment to accommodate reel-based component handling.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the Molex 0483950003 and Würth Elektronik 692121130100 are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Moisture sensitivity level is 1 (Unlimited) for both parts.
