Substitute Part Grouping Explanation
Substitute parts for the Amphenol RF 112659-75 are categorized based on the following substitution criteria:
Direct Mechanical & Electrical Equivalents (75 Ohm, Through Hole, Right Angle): Parts that match the primary impedance specification of 75 ohms with identical through-hole right-angle mounting configuration. These substitutes maintain full electrical and mechanical compatibility with the original part.
Panel Mount Variants (75 Ohm, Right Angle with Bulkhead Feature): Parts that retain 75 ohm impedance and right-angle configuration but include panel mount capability with bulkhead front-side nut fastening. These are suitable for applications requiring panel integration in addition to PCB mounting.
Parametric Equivalents (50 Ohm, Through Hole, Right Angle): Parts that differ in impedance specification (50 ohms instead of 75 ohms) but maintain identical mounting type, contact termination, and connector style. These are applicable only in systems designed for 50 ohm characteristic impedance.
The key parameters determining substitution eligibility are: connector style (BNC), connector type (jack/female socket), contact termination (solder), mounting type (through hole and/or panel mount), fastening type (bayonet lock), and impedance specification (75 ohms for direct equivalents; 50 ohms for parametric equivalents).

Engineering Selection Recommendations
For Direct 75 Ohm Equivalent Replacement:
The Rosenberger 71K201-400N5 is the primary direct equivalent for the Amphenol RF 112659-75. Both parts share identical impedance (75 ohms), mounting configuration (through-hole right-angle), connector type (BNC jack/female socket), and maximum frequency rating (4 GHz). Both are ROHS3 compliant and operate across the extended temperature range of -65°C to 165°C. The primary difference is the voltage rating: the Rosenberger part is rated at 400 V compared to the Amphenol part's 500 V rating. This substitution is suitable for applications where the 400 V rating is sufficient.
For 75 Ohm Panel Mount Applications:
The Winchester Interconnect parts 364A795, 364A795BL, and 364M2795 provide 75 ohm impedance with panel mount capability via bulkhead front-side nut fastening. These parts are suitable when panel integration is required in addition to PCB mounting. All three Winchester parts are RoHS compliant and operate to 165°C maximum. The frequency rating is limited to 1 GHz compared to the 4 GHz rating of the original part. The 364M2795 provides dual ports (2 ports) versus single port on the other variants. These substitutes are applicable only in applications with frequency requirements not exceeding 1 GHz.
For 50 Ohm System Applications:
The TE Connectivity 413631-2, 414373-1, and 5413631-1, along with Pomona Electronics 4788, Huber+Suhner 85_BNC-50-0-1/133_NE, and Hirose BNC-LR-PC-3(40) are parametric equivalents designed for 50 ohm systems. These parts maintain the through-hole right-angle solder termination and bayonet lock fastening but operate at 50 ohm impedance. Selection among these 50 ohm options depends on compliance requirements and operating temperature specifications:
- TE Connectivity 413631-2 and 5413631-1 are ROHS3 compliant with 4 GHz frequency rating. The 5413631-1 offers higher inventory availability (2230 pcs).
- Pomona Electronics 4788 is ROHS3 compliant, REACH unaffected, and operates across the extended temperature range (-65°C to 165°C).
- Huber+Suhner 85_BNC-50-0-1/133_NE is ROHS3 compliant and REACH unaffected with extended temperature range (-65°C to 165°C).
- Hirose BNC-LR-PC-3(40) offers the highest mating cycle rating (5000 cycles) and is RoHS compliant, suitable for high-cycle applications.
Compliance Considerations:
For applications requiring ROHS3 compliance, the Amphenol RF 112659-75, Rosenberger 71K201-400N5, Pomona Electronics 4788, TE Connectivity 5413631-1, and Huber+Suhner 85_BNC-50-0-1/133_NE are compliant options. The TE Connectivity 414373-1 is RoHS non-compliant and should not be selected for regulated applications. For REACH compliance, the Amphenol RF 112659-75 is REACH affected; Pomona Electronics 4788 and Huber+Suhner 85_BNC-50-0-1/133_NE are REACH unaffected.
Frequently Asked Questions (FAQ)
Q: Can I substitute a 50 ohm BNC connector for the 75 ohm Amphenol RF 112659-75?
A: Substitution is possible only if your system is designed for 50 ohm characteristic impedance. The 50 ohm variants (TE Connectivity 413631-2, 414373-1, 5413631-1, Pomona 4788, Huber+Suhner 85_BNC-50-0-1/133_NE, and Hirose BNC-LR-PC-3(40)) maintain identical mounting and termination characteristics but operate at different impedance. Using a 50 ohm connector in a 75 ohm system or vice versa will result in impedance mismatch and signal reflection.
Q: What is the difference between the Winchester 364A795 and 364M2795?
A: Both parts are 75 ohm BNC jacks with panel mount capability. The primary difference is the number of ports: 364A795 has 1 port, while 364M2795 has 2 ports. Both operate to 1 GHz maximum frequency and are RoHS compliant. The 364M2795 is part of the Dual 364 series and has higher inventory availability (3480 pcs).
Q: Why does the Rosenberger 71K201-400N5 have a lower voltage rating than the Amphenol part?
A: The Rosenberger 71K201-400N5 is rated at 400 V while the Amphenol RF 112659-75 is rated at 500 V. This difference reflects the design specifications of each manufacturer. The 400 V rating is sufficient for most standard applications. Selection should be based on your specific voltage requirements.
Q: Are the Winchester panel mount connectors compatible with PCB-only mounting?
A: The Winchester 364A795, 364A795BL, and 364M2795 feature both panel mount and through-hole capabilities. They can be used in PCB-only applications where the bulkhead feature is not utilized. However, the presence of the bulkhead nut and front-side mounting feature may affect PCB layout compared to the standard through-hole-only Amphenol part.
Q: What is the frequency limitation of the Winchester substitutes?
A: The Winchester 364A795, 364A795BL, and 364M2795 are rated to 1 GHz maximum frequency, compared to 4 GHz for the Amphenol RF 112659-75. These Winchester parts are suitable only for applications with frequency requirements not exceeding 1 GHz. For applications requiring 4 GHz operation, use the Rosenberger 71K201-400N5 (75 ohm) or the 50 ohm equivalents (TE Connectivity, Pomona, Huber+Suhner, or Hirose).
Q: Which substitute offers the best durability for high-cycle applications?
A: The Hirose BNC-LR-PC-3(40) offers 5000 mating cycles, significantly higher than the standard 500 mating cycles of most other substitutes. This makes the Hirose part suitable for applications requiring frequent connector mating and unmating. However, the Hirose part operates at 50 ohm impedance and is limited to -55°C to 85°C temperature range.
Q: What are the RoHS compliance differences among the substitutes?
A: The Amphenol RF 112659-75, Rosenberger 71K201-400N5, Pomona 4788, TE Connectivity 5413631-1, and Huber+Suhner 85_BNC-50-0-1/133_NE are ROHS3 compliant. The Winchester parts (364A795, 364A795BL, 364M2795) and Hirose BNC-LR-PC-3(40) are RoHS compliant. The TE Connectivity 414373-1 is RoHS non-compliant and should not be used in regulated applications.
Q: Can I use a substitute with a lower operating temperature range?
A: The TE Connectivity parts (413631-2, 414373-1, 5413631-1), Winchester parts (364A795, 364A795BL, 364M2795), and Hirose BNC-LR-PC-3(40) are limited to -55°C or -40°C minimum operating temperature, compared to the Amphenol part's -65°C minimum. These substitutes are suitable only if your application does not require operation below -40°C or -55°C respectively.
Q: What is the inventory status of the available substitutes?
A: Current inventory levels vary: Pomona 4788 (1047 pcs), Rosenberger 71K201-400N5 (1086 pcs), Hirose BNC-LR-PC-3(40) (1165 pcs), Winchester 364A795 (1557 pcs), TE Connectivity 5413631-1 (2230 pcs), and Winchester 364M2795 (3480 pcs). The Winchester 364M2795 offers the highest availability.
