Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1757099-1 with the Cinch Connectivity Solutions Trompeter UPL220-013 is based on the following alignment of critical parameters:

Matching Parameters:

• Connector Style: Both are BNC connectors
• Connector Type: Both are plug, male pin configurations
• Mounting Type: Both are free hanging (in-line)
• Fastening Type: Both use bayonet lock
• Frequency - Max: Both support 4 GHz
• Cable Group: Both support RG-59
• Voltage Rating: Both rated at 500 V
• Body Material: Both use brass construction
• Body Finish: Both have nickel finish
• Dielectric Material: Both use PTFE

Differing Parameters:

• Impedance: Main part is 50 ohms; substitute is 75 ohms
• Contact Termination: Main part uses solder; substitute uses crimp
• Operating Temperature: Main part -55°C ~ 85°C; substitute -65°C ~ 165°C
• Product Status: Main part is obsolete; substitute is active

The impedance difference (50 ohms versus 75 ohms) represents a fundamental electrical characteristic that affects signal transmission and system performance. This difference must be evaluated within the context of the specific application and system requirements.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1757099-1 is an obsolete component. The Cinch Connectivity Solutions Trompeter UPL220-013 is an active product with current manufacturing support and availability.

Compliance and Certification Status:

• Both components are classified under ECCN EAR99 and HTSUS 8536.69.4010
• Both have MSL rating of 1 (Unlimited)
• The UPL220-013 is RoHS3 compliant and REACH affected
• The 1757099-1 is REACH unaffected

Operational Considerations: The UPL220-013 provides an extended operating temperature range (-65°C ~ 165°C) compared to the 1757099-1 (-55°C ~ 85°C), offering broader environmental capability. The substitute part uses crimp termination for the center contact, whereas the original uses solder termination. The impedance specification differs between the two components (50 ohms versus 75 ohms), which represents a critical electrical parameter that must be evaluated against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the Cinch Connectivity UPL220-013 be used as a direct replacement for the TE Connectivity 1757099-1?

A: Both connectors share the same BNC style, male pin configuration, bayonet lock fastening, and 4 GHz frequency capability. However, the impedance differs (50 ohms versus 75 ohms), and the termination method for the center contact differs (solder versus crimp). These differences must be evaluated within the specific application context.

Q: What is the significance of the impedance difference between 50 ohms and 75 ohms?

A: Impedance is a fundamental electrical characteristic that affects signal transmission, reflection, and system performance. The choice between 50 ohm and 75 ohm systems is application-dependent and typically determined by the broader system architecture and cable specifications.

Q: Why does the TE Connectivity 1757099-1 use solder termination while the substitute uses crimp termination?

A: Solder and crimp terminations represent different assembly methods. Solder termination involves heat-based joining, while crimp termination uses mechanical compression. The selection between these methods depends on assembly process capabilities, reliability requirements, and system design specifications.

Q: What is the difference in operating temperature ranges?

A: The TE Connectivity 1757099-1 operates from -55°C to 85°C, while the Cinch Connectivity UPL220-013 operates from -65°C to 165°C. The substitute part provides a wider temperature envelope, which may be beneficial for applications requiring extended thermal performance.

Q: Is the Cinch Connectivity UPL220-013 currently available?

A: The UPL220-013 is classified as an active product with current manufacturing status, unlike the obsolete TE Connectivity 1757099-1.

Q: What cable types are compatible with each connector?

A: Both connectors support RG-59 cable. The TE Connectivity 1757099-1 additionally lists Belden 9266 compatibility.

Q: Are there any compliance or regulatory differences between these parts?

A: Both components share the same ECCN (EAR99) and HTSUS (8536.69.4010) classifications. The UPL220-013 is RoHS3 compliant and REACH affected, while the 1757099-1 is REACH unaffected. Both have MSL rating of 1 (Unlimited).
