Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 112494 are identified based on matching mechanical and electrical parameters that define functional equivalence in coaxial connector applications. The primary substitution criterion is the BNC connector style with female jack configuration, right-angle panel mount through-hole solder termination, and identical physical mounting characteristics.

The key parameters that determine substitution eligibility include:

• Connector Style: BNC
• Connector Type: Jack, Female Socket
• Mounting Type: Panel Mount, Through Hole, Right Angle
• Contact Termination: Solder
• Shield Termination: Solder
• Fastening Type: Bayonet Lock
• Features: Board Lock
• Body Material: Zinc Die Cast
• Body Finish: Nickel
• Center Contact Material: Phosphor Bronze
• Center Contact Plating: Gold
• Dielectric Material: Polypropylene (PP)
• Frequency - Max: 4 GHz
• Voltage Rating: 500 V
• Mating Cycles: 500

The impedance specification differs between the main part and substitute part, representing a distinct electrical characteristic that must be evaluated for application compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 112494 and 112487 are active products with ROHS3 compliance and REACH affected status, meeting current regulatory requirements for electronic component manufacturing and distribution. Both components maintain identical mechanical mounting characteristics, termination methods, and physical construction specifications.

The primary distinction between these parts is the impedance specification: 75 ohms for the 112494 and 50 ohms for the 112487. This electrical parameter must align with the system impedance requirements of the application. Selection between these parts is determined by the impedance specification required by the circuit design and signal transmission requirements.

Both parts are manufactured to identical quality standards with equivalent reliability characteristics, including 500 mating cycles and 500 volt voltage rating. The inventory status indicates both components are available in production quantities.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between Amphenol RF 112494 and 112487?

A: The primary difference is impedance specification. The 112494 is rated at 75 ohms, while the 112487 is rated at 50 ohms. All other mechanical and electrical parameters are identical.
