• Number of Ports: 1 (all substitutes match)

Secondary Variation Parameters:

• Impedance: 75 Ohms (main part) vs. 50 Ohms (most substitutes) or 75 Ohms (Rosenberger 71K201-400N5)
• Operating Temperature Range: Varies by manufacturer
• Body Material: Zinc Die Cast (main) vs. Zinc, Brass, or Brass alternatives
• Center Contact Material: Phosphor Bronze (main) vs. Beryllium Copper alternatives
• Dielectric Material: POM Acetal/PTFE (main) vs. PTFE, PMP, or PFA/PTFE alternatives
• RoHS Compliance: ROHS3 Compliant (main) vs. Not Applicable or Non-compliant options

Substitutes are grouped into two categories: 75 Ohm Impedance Match (direct electrical equivalent) and 50 Ohm Impedance Alternatives (functional substitutes for 50 ohm system applications).

Parameter Comparison

Engineering Selection Recommendations

Direct 75 Ohm Impedance Equivalent:

The Rosenberger 71K201-400N5 is the only substitute that maintains the 75 ohm impedance specification of the Amphenol RF 112762. This part is ROHS3 compliant, operates across an extended temperature range (-65°C to 165°C), and supports the same 4 GHz frequency maximum and 500 mating cycles. The voltage rating is 400 V, which is 100 V lower than the main part. Selection of this part is appropriate for applications where 75 ohm impedance is a system requirement and the 400 V rating is sufficient.

50 Ohm Impedance Alternatives:

Five substitute parts operate at 50 ohm impedance and are suitable for applications designed around 50 ohm RF systems. These parts maintain compatibility across connector style, mounting type, termination method, frequency range, and mating cycles.

TE Connectivity 5413631-1 is recommended as the primary 50 ohm alternative. This part is ROHS3 compliant, REACH affected (matching the main part's regulatory status), operates at -55°C to 85°C, and has the highest inventory availability (2230 units). The beryllium copper center contact and polymethylpentene dielectric provide stable electrical performance.

TE Connectivity 413631-2 is a secondary 50 ohm option with ROHS status not applicable and REACH status vendor undefined. Operating temperature range is -55°C to 85°C with 727 units in stock.

TE Connectivity 414373-1 is a 50 ohm alternative with RoHS non-compliant status, making it unsuitable for applications requiring RoHS compliance. This part is not recommended for new designs.

Pomona Electronics 4788 is a 50 ohm option with ROHS3 compliance and REACH unaffected status. This part operates across an extended temperature range (-65°C to 165°C) and has the highest inventory among 50 ohm alternatives (1047 units). Mating cycles are not specified.

Huber+Suhner 85_BNC-50-0-1/133_NE is a 50 ohm alternative with ROHS3 compliance and REACH unaffected status. Operating temperature range is -65°C to 165°C with 870 units in stock. Moisture sensitivity level is not applicable.

Regulatory and Compliance Considerations:

For applications requiring ROHS3 compliance, the following parts are suitable: Amphenol RF 112762 (main), Pomona Electronics 4788, TE Connectivity 5413631-1, Rosenberger 71K201-400N5, and Huber+Suhner 85_BNC-50-0-1/133_NE.

For applications where REACH affected status must match the main part, only TE Connectivity 5413631-1 and Rosenberger 71K201-400N5 are appropriate.

Frequently Asked Questions (FAQ)

Q: Can I use a 50 ohm BNC connector in place of the 75 ohm Amphenol RF 112762?

A: Substitution depends on system design. If your RF system is designed for 75 ohm impedance, using a 50 ohm connector introduces impedance mismatch, which causes signal reflections and degrades performance. If your system is designed for 50 ohm impedance, then 50 ohm substitutes are appropriate. The Rosenberger 71K201-400N5 maintains 75 ohm impedance and is the direct electrical equivalent.

Q: What is the difference between the TE Connectivity 5413631-1 and 413631-2?

A: Both are 50 ohm BNC jack connectors with identical mechanical and electrical specifications. The primary differences are center contact material (beryllium copper vs. beryllium copper), body finish (nickel vs. tin-lead), dielectric material (polymethylpentene vs. polytetrafluoroethylene), and regulatory status. The 5413631-1 is ROHS3 compliant and REACH affected, while the 413631-2 has not applicable RoHS status and vendor undefined REACH status. For new designs, 5413631-1 is preferred.

Q: Why does the Rosenberger 71K201-400N5 have a lower voltage rating (400 V vs. 500 V)?

A: The voltage rating difference reflects design and manufacturing specifications from different manufacturers. The 400 V rating is still suitable for most PCB-mounted RF applications. Verify that your application voltage requirements do not exceed 400 V before selecting this part.

Q: Are all substitute parts suitable for high-temperature applications?

A: No. The Amphenol RF 112762 does not specify an operating temperature range. TE Connectivity parts (413631-2, 414373-1, 5413631-1) operate at -55°C to 85°C. Pomona Electronics 4788, Rosenberger 71K201-400N5, and Huber+Suhner 85_BNC-50-0-1/133_NE operate at -65°C to 165°C. Select parts based on your application's temperature requirements.

Q: Which substitute has the best inventory availability?

A: TE Connectivity 5413631-1 has the highest inventory with 2230 units in stock, followed by Rosenberger 71K201-400N5 with 1086 units and Pomona Electronics 4788 with 1047 units.

Q: Is the Amphenol RF 112762 RoHS compliant?

A: Yes, the Amphenol RF 112762 is ROHS3 compliant. If RoHS compliance is required for your application, select from the following substitutes: Pomona Electronics 4788, TE Connectivity 5413631-1, Rosenberger 71K201-400N5, or Huber+Suhner 85_BNC-50-0-1/133_NE. Avoid TE Connectivity 414373-1, which is RoHS non-compliant.

Q: What does "Moisture Sensitivity Level 1 (Unlimited)" mean?

A: MSL 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. Parts with MSL 1 can be stored in standard conditions without desiccant packaging.

Q: Can I mix different substitute parts in the same PCB assembly?

A: Yes, all substitute parts are mechanically and electrically compatible for through-hole PCB mounting. However, ensure that your RF system design accommodates the impedance of the selected connector. Do not mix 75 ohm and 50 ohm connectors in the same signal path.

Q: What is the difference between phosphor bronze and beryllium copper center contacts?

A: Both materials provide reliable electrical contact and mechanical durability. Phosphor bronze (used in the main part and TE Connectivity 414373-1) offers good spring properties and corrosion resistance. Beryllium copper (used in TE Connectivity 413631-2, Pomona Electronics 4788, TE Connectivity 5413631-1, Rosenberger 71K201-400N5, and Huber+Suhner 85_BNC-50-0-1/133_NE) provides superior electrical conductivity and fatigue resistance. Both are suitable for RF applications.
