Substitute Part Grouping Explanation

Substitute part identification for the TE Connectivity 118438-1 is based on the following critical parameters that define functional equivalency within the rectangular connector category:

Primary Substitution Criteria:

• Contact type: Socket configuration
• Contact finish material: Gold plating
• Connector category: Rectangular connectors
• Functional application: PCB-mounted socket contacts

The identified substitute part, Molex 0002065135, shares the core functional characteristics of socket contact geometry and gold finish specification. Both parts serve the rectangular connector socket contact function and are classified within the same product category. The substitute part is actively produced and maintains full inventory availability.

Substitution logic is based strictly on matching the socket contact function, gold finish requirement, and rectangular connector classification. No additional technical assumptions beyond the provided parameters are applied to this substitution relationship.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 118438-1 (Primary Part): The primary part is available in substantial inventory quantity (643 pieces) as new original stock. Product status information is not provided in the available documentation.

Molex 0002065135 (Substitute Part): The Molex 0002065135 is classified as an active product with confirmed ongoing production status. This part carries RoHS3 compliance certification and REACH unaffected status, indicating full compliance with current environmental and regulatory standards. The part maintains an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. The substitute part is available in higher inventory quantity (4084 pieces), supporting extended supply chain availability.

Selection between the primary and substitute part should be based on application-specific requirements, connector series compatibility with existing assemblies, and procurement lead time considerations. Both parts function as socket contacts with gold finish in the rectangular connector category.

Frequently Asked Questions (FAQ)

Q: What defines the substitution relationship between TE Connectivity 118438-1 and Molex 0002065135?

A: Both parts are socket contacts with gold finish in the rectangular connector category. The substitution is based on matching the socket contact function and gold plating specification. The parts belong to different connector series (Economate II versus 1855) and may have different mechanical interfaces within their respective connector systems.

Q: Are there differences in termination methods between these parts?

A: The TE Connectivity 118438-1 is specified for solder termination on PCB. The Molex 0002065135 is specified for crimp termination. These represent different assembly methods and may not be directly interchangeable in all applications without connector system compatibility verification.

Q: What is the significance of the wire gauge specification on the Molex part?

A: The Molex 0002065135 includes a wire gauge specification of 24-30 AWG, which defines the acceptable wire diameter range for crimp termination. This parameter is specific to the crimp termination method and does not apply to the solder termination method of the primary part.

Q: How do the inventory quantities compare?

A: The TE Connectivity 118438-1 has 643 pieces in stock, while the Molex 0002065135 has 4084 pieces available. The higher inventory of the substitute part may provide extended availability for high-volume procurement requirements.

Q: What compliance certifications apply to the substitute part?

A: The Molex 0002065135 carries RoHS3 compliance certification and is REACH unaffected. The part has an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used interchangeably in existing connector assemblies?

A: Direct interchangeability depends on the specific connector housing and assembly design. The parts belong to different connector series and may have different mechanical dimensions or interface specifications. Connector system compatibility must be verified before substitution in existing designs.
