Engineering Selection Recommendations

All listed substitute parts are active products with confirmed availability. The following factors support selection of substitute parts:

Compliance and Certification: All Molex (0676430910, 0676432910, 0676432911, 0676433910, 0676433911), Würth Elektronik (61400416021), Mill-Max Manufacturing Corp. (896-43-004-90-000000), Pulse Electronics (E8144-A01321-L), and Kycon (KUSBEX-ASFS1N-B, KUSBEX-ASFS1N-B30) substitute parts are ROHS3 compliant and REACH unaffected, providing regulatory alignment for modern applications.

Inventory Availability: Substitute parts demonstrate robust stock levels. Molex 0676433910 offers the highest inventory at 23,312 pieces, followed by Molex 0676432911 at 12,662 pieces and Mill-Max 896-43-004-90-000000 at 9,858 pieces. These inventory levels support both immediate and sustained procurement requirements.

Product Status: All substitute parts maintain active product status, ensuring continued manufacturer support and supply chain stability.

Mechanical and Electrical Interface Compatibility: All substitute parts satisfy the critical interface requirements: USB-A receptacle configuration, 4-position contact arrangement, through-hole right-angle mounting with horizontal orientation, solder termination, shielded construction, gold contact finish, board lock feature, and UL94 V-0 flammability rating.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0676432910 be used as a direct replacement for the TE Connectivity 1775247-3?

A: Yes. Both connectors share identical mechanical and electrical interface specifications: USB-A receptacle, 4 positions, through-hole right-angle mounting, solder termination, shielded design, gold contacts, board lock feature, and UL94 V-0 flammability rating. The Molex part operates across -40°C to 85°C with 1.5A current rating and 30VDC voltage rating.

Q: What is the difference between Molex 0676432910 and 0676432911?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary distinction is insulation color: 0676432910 features black insulation, while 0676432911 features white insulation. Selection between these variants depends on application-specific color coding requirements.

Q: Are the Kycon KUSBEX-ASFS1N-B and KUSBEX-ASFS1N-B30 interchangeable?

A: Yes. Both Kycon parts meet all critical substitution parameters and are mechanically and electrically compatible. Both operate across -40°C to 105°C with 1.5A current rating, 30VAC voltage rating, and 1500 mating cycles. The designation difference reflects internal part numbering; both are suitable for the same applications.

Q: Does the operating temperature range affect substitution eligibility?

A: Operating temperature range does not preclude substitution. The TE Connectivity 1775247-3 does not specify an operating temperature range. Substitute parts with defined temperature ranges (such as Molex -40°C to 85°C or Würth Elektronik -40°C to 105°C) provide additional thermal performance specification. Selection should account for application thermal requirements.

Q: What is the significance of ROHS3 compliance on substitute parts?

A: ROHS3 compliance indicates conformance to Restriction of Hazardous Substances Directive 3, restricting specific hazardous materials in electrical and electronic equipment. All substitute parts listed are ROHS3 compliant, supporting regulatory requirements in markets where ROHS3 compliance is mandated. The primary part lists RoHS status as "Not applicable," which does not indicate non-compliance but rather that the part predates or falls outside ROHS3 classification scope.

Q: Can I use the Mill-Max 896-43-004-90-000000 in applications requiring higher current capacity?

A: The Mill-Max part is rated for 1A current capacity, compared to the TE Connectivity 1775247-3 which does not specify a current rating. If the application requires current capacity exceeding 1A, alternative substitutes such as Molex 0676432910 or 0676432911 (rated 1.5A) or Würth Elektronik 61400416021 (rated 1.5A) are more appropriate selections.

Q: What packaging format are these substitute parts supplied in?

A: All substitute parts are supplied in tray packaging, suitable for automated assembly processes and bulk component handling. The primary TE Connectivity part does not specify packaging format in the provided data.

Q: Are there any mating cycle differences between substitute options?

A: The TE Connectivity 1775247-3 does not specify mating cycle rating. Several substitute parts provide mating cycle specifications: Würth Elektronik 61400416021, Mill-Max 896-43-004-90-000000, Pulse Electronics E8144-A01321-L, and both Kycon variants specify 1500 mating cycles. Molex parts do not specify mating cycle ratings. For applications with defined mating cycle requirements, parts with specified ratings provide additional performance documentation.
