Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 112952 are grouped into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Amphenol RF Series): Parts 112119 and 112123 are direct parametric equivalents sharing identical electrical specifications with the main part: 75 ohm impedance, BNC connector style, male pin configuration, crimp termination, bayonet lock fastening, 4 GHz maximum frequency, and 500 V voltage rating. These parts differ in product status and dielectric material composition but maintain full functional compatibility within the 75 ohm cable group applications.

Similar Alternatives (Cinch Connectivity Solutions Trompeter UPL220 Series): Parts UPL220-009, UPL220-025, and UPL220-026 are similar alternatives from a different manufacturer. These connectors match the core electrical parameters (75 ohm impedance, BNC style, male pin, crimp termination, bayonet lock, 4 GHz frequency, 500 V rating) and mounting configuration. Differences exist in cable group compatibility, packaging format, and included component count.

Non-Equivalent Alternative: Part 112118 is a 50 ohm BNC connector plug and is not electrically compatible with the 75 ohm main part due to impedance mismatch. This part is listed for reference only and is not suitable for direct substitution in 75 ohm applications.

Engineering Selection Recommendations

Primary Substitutes (Amphenol RF 112119 and 112123): Both parts are recommended as primary substitutes for the 112952. Part 112123 is preferred for new designs due to its active product status. Part 112119 carries a "Not For New Designs" designation and should be used only when existing inventory or legacy system compatibility is required. Both maintain full electrical and mechanical compatibility with the main part.

Secondary Alternatives (Cinch Connectivity Solutions Trompeter UPL220 Series): The UPL220-009, UPL220-025, and UPL220-026 connectors are suitable alternatives when cross-manufacturer sourcing is acceptable. All three maintain active product status and ROHS3 compliance. Selection among these three variants depends on cable group compatibility: UPL220-009 for Belden 8218 and Essex 21-597 cables, UPL220-025 for 734A cable group, and UPL220-026 for 735A cable group. These parts are supplied in bulk packaging rather than bagged format.

Non-Recommended: Part 112118 (50 ohm impedance) is not suitable for substitution in 75 ohm applications and should not be selected.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 112952 be directly replaced with part 112123?

A: Yes. Part 112123 is a parametric equivalent with identical electrical specifications (75 ohm impedance, BNC connector style, male pin, crimp termination, bayonet lock fastening, 4 GHz frequency, 500 V rating) and mounting configuration. Part 112123 is in active product status, making it the preferred choice for new designs.

Q: What is the difference between the Amphenol RF 112952 and the Cinch Connectivity Solutions Trompeter UPL220 series?

A: Both product lines share identical core electrical and mechanical parameters: 75 ohm impedance, BNC connector style, male pin configuration, crimp termination, bayonet lock fastening, 4 GHz maximum frequency, and 500 V voltage rating. The primary differences are manufacturer, packaging format (Amphenol RF supplied in bags; Cinch in bulk), cable group compatibility, and included component count. Selection depends on cable type and packaging requirements.

Q: Why is part 112118 listed but not recommended?

A: Part 112118 is a 50 ohm BNC connector plug, which differs from the 75 ohm impedance of the main part 112952. Impedance mismatch prevents direct substitution. This part is included for reference only to clarify that 50 ohm and 75 ohm connectors are not interchangeable.

Q: Are the Cinch UPL220-009, UPL220-025, and UPL220-026 connectors interchangeable with each other?

A: All three Cinch UPL220 variants share identical electrical and mechanical specifications. The differences are in cable group compatibility: UPL220-009 is specified for Belden 8218, YR23023, and Essex 21-597 cables; UPL220-025 for 734A cable; and UPL220-026 for 735A cable. Selection should be based on the specific cable type in the application.

Q: What is the significance of the "Not For New Designs" status on part 112119?

A: This designation indicates that while part 112119 remains functionally equivalent and available in inventory, Amphenol RF recommends using alternative parts for new product development. Part 112123, which carries active status, is the recommended choice for new designs requiring a 75 ohm Amphenol RF BNC connector plug.

Q: Do all substitute parts meet the same compliance standards as the main part?

A: Yes. All listed substitute parts (112119, 112123, UPL220-009, UPL220-025, and UPL220-026) are ROHS3 compliant and REACH affected, matching the compliance profile of the main part 112952.

Q: What is the difference in packaging between Amphenol RF and Cinch Connectivity Solutions Trompeter parts?

A: Amphenol RF 112952, 112119, and 112123 are supplied in bag packaging. Cinch Connectivity Solutions Trompeter UPL220 series parts (UPL220-009, UPL220-025, UPL220-026) are supplied in bulk packaging. Additionally, Amphenol RF parts include three components (connector, contact, ferrule), while Cinch parts include two components (connector, contact).
