• Maximum frequency (8 GHz)
• Number of ports (1)

Mechanical Parameters:

• Connector type (Jack, Female Socket)
• Mounting configuration (Panel Mount, Through Hole, Right Angle)
• Mounting feature (Bulkhead - Front Side Nut)
• Termination method (Solder for both contact and shield)
• Fastening type (Snap-On)

Material Specifications:

• Center contact material (Beryllium Copper)
• Center contact plating (Gold)
• Dielectric material (PEEK, PTFE)

Reliability Parameters:

• Mating cycles (500)
• Moisture sensitivity level (MSL 1)

Engineering Selection Recommendations

The TE Connectivity 2-1393681-2 is the direct equivalent substitute for the obsolete 2-1393681-3. Both components share the same base product number (1393681) and maintain complete electrical and mechanical parameter equivalence across all critical specifications.

Primary Advantage of 2-1393681-2: The substitute part carries Active product status, ensuring ongoing availability and supply chain continuity. The 2-1393681-2 is RoHS Compliant, meeting current environmental and regulatory requirements for new system designs and manufacturing processes.

Dielectric Material Consideration: The main part specifies both PEEK and PTFE dielectric materials, while the substitute specifies PEEK only. PEEK is a high-performance engineering polymer that meets or exceeds the electrical and thermal performance requirements of the application. This represents a material refinement rather than a compromise in component capability.

Compliance and Certification: Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications. The substitute's RoHS Compliant status aligns with modern manufacturing standards and regulatory frameworks.

Frequently Asked Questions (FAQ)

Q: Can the 2-1393681-2 be used as a direct replacement for the 2-1393681-3 in existing designs?

A: Yes. The 2-1393681-2 maintains complete electrical and mechanical equivalence with the 2-1393681-3 across all specified parameters, including connector style, impedance, frequency rating, mounting configuration, and termination method. No design modifications are required.

Q: What is the difference between the two parts?

A: The primary differences are product status and compliance certification. The 2-1393681-3 is obsolete, while the 2-1393681-2 is active. The 2-1393681-2 carries RoHS Compliant certification. The dielectric material specification differs slightly: the main part lists both PEEK and PTFE, while the substitute specifies PEEK only. PEEK provides equivalent or superior performance for this application.

Q: Are there packaging differences between these parts?

A: The 2-1393681-3 packaging is not specified in the available data. The 2-1393681-2 is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the inventory status of the substitute part?

A: The 2-1393681-2 has 916 pieces in stock as new original inventory, compared to 729 pieces available for the obsolete 2-1393681-3.

Q: Are both parts manufactured by the same company?

A: Yes. Both the 2-1393681-3 and 2-1393681-2 are manufactured by TE Connectivity AMP Connectors and share the same base product number (1393681).

Q: What are the key electrical specifications that determine substitution compatibility?

A: The critical electrical parameters are connector style (1.6/5.6), impedance (75 Ohms), and maximum frequency (8 GHz). Both parts are identical in these specifications.

Q: What mounting configurations do these connectors support?

A: Both connectors feature panel mount, through-hole, right-angle orientation with bulkhead front-side nut mounting and snap-on fastening. They are designed for PCB integration with solder termination for both center contact and shield.
