RP-1106-C Equivalent & Substitute Parts

Part Overview

The RP-1106-C is an RP-BNC connector plug with female socket configuration manufactured by RF Industries. This coaxial connector is designed for 50-ohm RF applications with crimp termination on both center contact and shield. The component is currently in active product status with 625 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, including impedance, frequency rating, connector style, termination method, and cable compatibility. Alternative sources become necessary for supply chain continuity, inventory management, or when the primary part reaches end-of-life status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP-1106-C is determined by strict equivalence across the following critical parameters:

Electrical Equivalence:

• Impedance: 50 Ohms (mandatory match)
• Frequency rating: 4 GHz maximum (substitute must meet or exceed)
• Voltage rating: 500 V (substitute must meet or exceed)

Mechanical Equivalence:

• Connector style: RP-BNC (exact match required)
• Connector type: Plug, Female Socket (exact match required)
• Fastening type: Bayonet Lock (exact match required)
• Mounting configuration: Free Hanging (In-Line) (exact match required)

Termination Compatibility:

• Contact termination: Crimp (substitute must support crimp method)
• Shield termination: Crimp (substitute must support crimp method)
• Cable group compatibility: RG-58, 58A, 58C, 141, 141A (substitute must support primary cable types)

Environmental & Compliance:

• Operating temperature: -65°C ~ 165°C (substitute must meet or exceed range)
• RoHS3 compliance (mandatory for equivalent status)
• MSL rating: 1 (Unlimited) (substitute must match or exceed)

The substitute part 031-5705 from Amphenol RF meets all mandatory electrical, mechanical, and termination criteria for direct substitution with the RP-1106-C.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RP-1106-C): The RP-1106-C from RF Industries is the recommended selection for new designs. This component maintains active product status with full manufacturer support and 625 units currently in inventory. The part is ROHS3 compliant and carries unlimited moisture sensitivity level rating, suitable for standard storage and handling conditions.

Substitute Selection (031-5705): The Amphenol RF 031-5705 serves as a direct electrical and mechanical equivalent for the RP-1106-C. All critical parameters including impedance, frequency rating, connector geometry, and termination methods are equivalent. The substitute part is also ROHS3 compliant with identical operating temperature and voltage specifications.

The 031-5705 carries a "Not For New Designs" product status designation. This classification indicates the part remains available for existing applications and legacy system support but should not be selected for new product development initiatives. The substitute part includes additional specifications not provided for the primary part: 500 mating cycles and 0.2 dB insertion loss, which may be relevant for specific application requirements.

Selection Criteria:

• Use RP-1106-C for new designs and applications requiring active manufacturer support
• Use 031-5705 for replacement, repair, or legacy system applications where the primary part is unavailable
• Both parts support identical cable groups (RG-58, 58A, 58C, 141, 141A) with the substitute offering extended compatibility to RG-58B, RG-303, LMR-195, Belden B7806A, and 9907 cables
• Both parts meet identical environmental and compliance requirements

Frequently Asked Questions (FAQ)

Q: Can the 031-5705 be used as a direct replacement for the RP-1106-C in existing assemblies?

A: Yes. The 031-5705 is electrically and mechanically equivalent to the RP-1106-C. Both connectors maintain 50-ohm impedance, identical frequency rating of 4 GHz, matching operating temperature range of -65°C to 165°C, and equivalent 500 V voltage rating. The bayonet lock fastening, free-hanging in-line mounting, and crimp termination methods are identical. Both parts are ROHS3 compliant with unlimited moisture sensitivity level rating.

Q: What does "Not For New Designs" mean for the 031-5705?

A: This product status indicates the 031-5705 remains available for purchase and use in existing applications, repair operations, and legacy system support. However, Amphenol RF does not recommend this part for incorporation into newly developed products or systems. For new design initiatives, the RP-1106-C from RF Industries is the appropriate selection.

Q: Are there cable compatibility differences between these two parts?

A: Both parts support RG-58, 58A, 58C, 141, and 141A cable groups. The 031-5705 offers extended cable compatibility including RG-58B, RG-303, LMR-195, Belden B7806A, and 9907. If your application uses only the standard cable group, both parts are fully compatible. If extended cable types are required, the 031-5705 provides broader compatibility options.

Q: What is the difference between crimp and crimp-or-solder termination?

A: The RP-1106-C specifies crimp termination for both center contact and shield. The 031-5705 specifies crimp or solder termination for the center contact while maintaining crimp termination for the shield. Both parts support the crimp method, ensuring compatibility. The 031-5705 offers additional flexibility through solder termination option if required by specific assembly processes.

Q: Are both parts suitable for the same frequency and impedance applications?

A: Yes. Both the RP-1106-C and 031-5705 are rated for 4 GHz maximum frequency and 50-ohm impedance. They are electrically equivalent for RF applications within this frequency range and impedance specification.

Q: What is the significance of the mating cycles specification on the 031-5705?

A: The 031-5705 specifies 500 mating cycles, indicating the connector can withstand 500 connect-disconnect cycles while maintaining electrical and mechanical integrity. The RP-1106-C does not provide this specification in the available documentation. For applications requiring frequent mating cycles, the 031-5705 provides documented cycle rating.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the RP-1106-C and 031-5705 are ROHS3 compliant, operate across the identical temperature range of -65°C to 165°C, carry 500 V voltage rating, and maintain MSL rating of 1 (Unlimited). Both parts use identical materials: brass body with nickel finish, gold-plated center contact, and PTFE dielectric.

Q: What inventory considerations should be evaluated?

A: The RP-1106-C currently has 625 units in stock. The 031-5705 has 856 units available. For immediate procurement needs, the 031-5705 offers higher inventory availability. For long-term supply chain planning, the RP-1106-C's active product status provides greater assurance of continued availability.
