Substitute Part Grouping Explanation
Substitute parts for the TE Connectivity 1-1337446-0 are identified based on strict alignment of core electrical and mechanical parameters. The primary substitution criteria include connector style (BNC), connector type (jack, female socket), impedance rating (50 ohms), contact and shield termination method (solder cup and solder), mounting configuration (panel mount with flange), and fastening mechanism (bayonet lock). All substitute parts maintain the same dielectric material (PTFE), body material (brass), voltage rating (500 V), mating cycle rating (500), and moisture sensitivity level (1 - Unlimited). Substitutes are classified into two categories: direct style equivalents that maintain identical BNC connector geometry and fastening, and parametric equivalents that satisfy all core electrical requirements while maintaining mechanical compatibility. Frequency rating, body finish, and center contact plating may vary among substitutes while preserving functional equivalence within the specified parameter set.

Engineering Selection Recommendations
The Amphenol RF 31-203-RFX represents a direct BNC connector substitute for the TE Connectivity 1-1337446-0, maintaining identical connector style, fastening mechanism (bayonet lock), and all core electrical parameters. Both parts are ROHS3 compliant and REACH affected, with equivalent moisture sensitivity classification. The 31-203-RFX operates across an extended temperature range (-65°C to 165°C) compared to the original part (-40°C to 85°C) and supports higher frequency operation (4 GHz versus 2 GHz), providing enhanced performance margins in applications within the original specification envelope.
The Radiall USA R316603000 provides parametric equivalence with identical BNC connector style, bayonet fastening, and electrical ratings. This part matches the original 2 GHz frequency maximum and maintains ROHS3 compliance and REACH affected status. The R316603000 operates across -55°C to 155°C and features beryllium copper center contact material in place of phosphor bronze, with nickel body finish and silver center contact plating.
The Amphenol RF 122248 represents a connector style variant, utilizing TNC receptacle configuration with threaded fastening instead of BNC bayonet lock. While maintaining 50 ohm impedance, solder cup termination, and panel mount flange configuration, the TNC connector style and threaded fastening mechanism create mechanical incompatibility with BNC mating interfaces. This part is suitable only for applications where TNC connector interfaces are specified and bayonet lock fastening is not required.
All substitute parts maintain active product status and equivalent compliance certifications. Selection between direct BNC equivalents (31-203-RFX and R316603000) depends on application-specific requirements for operating temperature range and frequency performance. The TNC variant (122248) requires mechanical interface redesign and is not interchangeable with the original BNC connector specification.
Frequently Asked Questions (FAQ)
Q: Can the Amphenol RF 31-203-RFX directly replace the TE Connectivity 1-1337446-0 in existing assemblies?
A: Yes. Both parts share identical BNC connector style, bayonet lock fastening, 50 ohm impedance, solder cup termination, panel mount flange configuration, and core electrical ratings. The 31-203-RFX operates within the original part's frequency and voltage specifications while providing extended temperature range capability.
Q: What is the primary difference between the Radiall USA R316603000 and the TE Connectivity 1-1337446-0?
A: The R316603000 maintains identical connector style, fastening, impedance, and frequency ratings. Differences include center contact material (beryllium copper versus phosphor bronze), body finish (nickel versus silver), and operating temperature range (-55°C to 155°C versus -40°C to 85°C). Both parts are ROHS3 compliant and REACH affected.
Q: Why is the Amphenol RF 122248 listed as a substitute if it uses TNC connector style?
A: The 122248 is listed as a parametric equivalent based on electrical characteristics (50 ohm impedance, solder cup termination, 500 V rating, PTFE dielectric). However, the TNC connector style and threaded fastening mechanism create mechanical incompatibility with BNC mating interfaces. This part is suitable only for applications where TNC connectors are specified.
Q: Are all substitute parts RoHS compliant?
A: Yes. The TE Connectivity 1-1337446-0, Amphenol RF 31-203-RFX, and Amphenol RF 122248 are ROHS3 compliant. The Radiall USA R316603000 is also ROHS3 compliant. All parts are REACH affected except the R316603000, which carries REACH affected status.
Q: What packaging formats are available for these coaxial RF connectors?
A: The TE Connectivity 1-1337446-0 is supplied in bulk packaging. The Amphenol RF 31-203-RFX is supplied in bulk packaging. The Radiall USA R316603000 is supplied in box packaging. The Amphenol RF 122248 is supplied in bag packaging. Packaging format does not affect electrical or mechanical compatibility.
Q: Can frequency rating differences affect substitution decisions?
A: Frequency ratings indicate maximum operational capability. The TE Connectivity 1-1337446-0 is rated to 2 GHz. The Amphenol RF 31-203-RFX supports 4 GHz, and the Amphenol RF 122248 supports 11 GHz. Substitutes with higher frequency ratings operate within the original specification and provide performance margin. Substitutes must not be used in applications exceeding their rated frequency maximum.
Q: What is the significance of moisture sensitivity level classification?
A: All parts except the Radiall USA R316603000 carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling. The R316603000 carries Not Applicable classification. This parameter does not affect electrical or mechanical compatibility.
