Substitute Part Grouping Explanation

Substitution eligibility for the 031-6157 is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Connector style (TNC)
• Connector type (Plug, Male Pin)
• Impedance (50 Ohms)
• Contact termination method (Solder)
• Shield termination method (Crimp)
• Mounting configuration (Free Hanging, Right Angle)
• Fastening type (Threaded)
• Frequency rating (11 GHz maximum)
• Cable group compatibility (RG-58 series and equivalent)

The 031-5849-RFX meets all critical electrical and mechanical parameters required for direct substitution in applications where the operating temperature range and product lifecycle status are acceptable. Both parts share identical connector geometry, impedance characteristics, and cable compatibility specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (031-6157): The 031-6157 is the recommended choice for new designs. This part maintains active production status and supports the extended operating temperature range of -65°C to 165°C. The PTFE dielectric material provides superior high-temperature performance. This connector is suitable for applications requiring full temperature envelope operation and long-term component availability.

Substitute Selection (031-5849-RFX): The 031-5849-RFX is classified as "Not For New Designs" and represents a legacy component option. This part is suitable only for replacement or repair of existing systems where the operating temperature range of -40°C to 85°C is acceptable. The POM acetal dielectric material differs from the primary part. Selection of this substitute requires explicit engineering justification based on existing system requirements and documented compatibility.

Both parts maintain ROHS3 compliance and REACH compliance status, ensuring regulatory alignment for their respective application contexts.

Frequently Asked Questions (FAQ)

Q: Can the 031-5849-RFX be used as a direct replacement for the 031-6157 in new designs?

A: No. The 031-5849-RFX carries a "Not For New Designs" product status designation. New designs must specify the 031-6157. The substitute part is limited to replacement applications in existing systems where operating conditions fall within its specified temperature range.

Q: What is the primary difference between these two TNC connectors?

A: The main differences are product lifecycle status, operating temperature range, and dielectric material. The 031-6157 operates from -65°C to 165°C with PTFE dielectric, while the 031-5849-RFX operates from -40°C to 85°C with POM acetal dielectric. Both maintain identical electrical specifications and mechanical compatibility.

Q: Are both parts compatible with the same cable types?

A: Yes. Both the 031-6157 and 031-5849-RFX support identical cable group compatibility: RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907.

Q: What is the significance of the dielectric material difference?

A: The 031-6157 uses PTFE (Polytetrafluoroethylene), which provides superior thermal stability and performance at elevated temperatures. The 031-5849-RFX uses POM acetal, which has a lower maximum operating temperature. Material selection affects the connector's performance envelope and suitability for specific thermal environments.

Q: Can I use the 031-5849-RFX in an application with a maximum operating temperature of 100°C?

A: No. The 031-5849-RFX maximum operating temperature is 85°C. An application requiring 100°C operation must use the 031-6157, which supports temperatures up to 165°C.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 031-6157 and 031-5849-RFX are ROHS3 compliant and REACH affected, meeting current environmental and regulatory requirements.

Q: What is the packaging configuration for both parts?

A: Both parts are supplied in bulk packaging. Each connector includes three components: 1 connector, 1 end cap, and 1 ferrule.

Q: How many mating cycles are rated for these connectors?

A: Both parts are rated for 500 mating cycles, indicating equivalent mechanical durability for connection and disconnection operations.
