Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 031-80103 are organized into two primary categories based on electrical and mechanical compatibility:

Direct Electrical Equivalents (75 Ohm Impedance)

Parts that maintain identical impedance specification (75 Ohms) with the main part are classified as direct equivalents. These parts share the same connector style (BNC), connector type (Plug, Male Pin), contact termination (Crimp), shield termination (Crimp), mounting type (Free Hanging In-Line), fastening type (Bayonet Lock), frequency rating (4 GHz), and voltage rating (500 V). Direct equivalents differ primarily in product status, packaging format, body material composition, or dielectric material selection. The following parts meet these criteria: Amphenol RF 112952, Amphenol RF 112119, Amphenol RF 112123, and Cinch Connectivity Solutions Trompeter UPL220-013.

Parametric Equivalents (50 Ohm Impedance)

Parts that differ in impedance specification (50 Ohms instead of 75 Ohms) are classified as parametric equivalents. These parts maintain all other electrical and mechanical parameters identical to the main part, including connector style, connector type, termination methods, mounting configuration, fastening mechanism, frequency rating, and voltage rating. Parametric equivalents are suitable only for applications designed for 50 ohm impedance systems. The following parts meet these criteria: Amphenol RF 112118 and Amphenol RF 112122.

Parameter Comparison

Engineering Selection Recommendations

For Direct Electrical Equivalents (75 Ohm Applications)

When selecting a direct substitute for the 031-80103 in 75 ohm impedance applications, Amphenol RF 112123 is the primary recommendation due to its Active product status, indicating ongoing manufacturer support and availability. This part maintains all electrical and mechanical parameters identical to the main part while providing superior lifecycle assurance for new system designs and long-term procurement planning.

Amphenol RF 112952 serves as an alternative direct equivalent with Active product status and identical electrical specifications. This part is suitable for applications where packaging format (Bag) is acceptable.

Amphenol RF 112119 and the main part 031-80103 share identical specifications but both carry "Not For New Designs" status. These parts are appropriate for legacy system maintenance and repair applications where component continuity is required.

Cinch Connectivity Solutions Trompeter UPL220-013 provides a cross-manufacturer direct equivalent with Active product status. This part is suitable for applications where multi-source component qualification is required or where Cinch Connectivity Solutions Trompeter components are preferred within the system design.

For Parametric Equivalents (50 Ohm Applications)

Amphenol RF 112122 is the primary recommendation for 50 ohm impedance applications, offering Active product status with identical mechanical and electrical parameters except for impedance specification. This part is suitable for new designs requiring 50 ohm characteristic impedance.

Amphenol RF 112118 serves as an alternative 50 ohm equivalent with "Not For New Designs" status, appropriate for legacy system support where 50 ohm impedance is required.

Compliance and Certification Basis

All substitute parts listed maintain ROHS3 compliance and REACH affected status consistent with the main part. All parts carry EAR99 ECCN classification and identical HTSUS coding (8536.69.4010), confirming regulatory equivalence for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can Amphenol RF 112123 be used as a direct replacement for 031-80103?

A: Yes. Amphenol RF 112123 is a direct electrical equivalent with identical impedance (75 Ohms), connector style (BNC), connector type (Plug, Male Pin), termination methods (Crimp), mounting configuration (Free Hanging In-Line), fastening mechanism (Bayonet Lock), frequency rating (4 GHz), and voltage rating (500 V). The primary difference is product status: 112123 is Active while 031-80103 is Not For New Designs. For new system designs, 112123 is the recommended selection.

Q: What is the difference between the 75 ohm and 50 ohm substitute parts?

A: The 75 ohm parts (112952, 112119, 112123, UPL220-013) are direct electrical equivalents suitable for systems designed for 75 ohm characteristic impedance. The 50 ohm parts (112118, 112122) differ only in impedance specification and are suitable for systems designed for 50 ohm characteristic impedance. All other electrical and mechanical parameters remain identical. Selection depends on the impedance requirement of the target application.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Bulk or Bag) does not affect electrical or mechanical performance. The choice between Bulk and Bag packaging is determined by procurement requirements, inventory management practices, and handling procedures. Electrical specifications, impedance, frequency rating, and voltage rating remain identical regardless of packaging format.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (112952, 112119, 112123, 112118, 112122, UPL220-013) are ROHS3 compliant, matching the compliance status of the main part 031-80103. All parts are also REACH affected and carry EAR99 ECCN classification.

Q: Can I use Cinch Connectivity Solutions Trompeter UPL220-013 in place of an Amphenol RF part?

A: Yes. Cinch Connectivity Solutions Trompeter UPL220-013 is a direct electrical equivalent with identical impedance (75 Ohms), connector specifications, termination methods, and electrical ratings. This part is suitable for applications where cross-manufacturer qualification is acceptable or required. The part carries Active product status and ROHS3 compliance.

Q: What is the significance of "Not For New Designs" status?

A: "Not For New Designs" indicates that the manufacturer is not recommending the part for new system development. These parts remain available for legacy system support, maintenance, and repair applications. For new designs, parts with Active status (112123, 112952, 112122, UPL220-013) are recommended to ensure long-term availability and manufacturer support.

Q: Are there operating temperature differences between substitute parts?

A: The main part 031-80103 specifies operating temperature range of -65°C to 165°C. Amphenol RF substitute parts (112952, 112119, 112123, 112118, 112122) do not specify operating temperature in the provided data. Cinch Connectivity Solutions Trompeter UPL220-013 specifies identical operating temperature range (-65°C to 165°C). For applications with specific temperature requirements, confirmation of operating temperature specifications is necessary for parts where this parameter is not provided.
