APH-SMAJ-NJ Equivalent & Substitute Parts

Part Overview

The APH-SMAJ-NJ is a coaxial adapter connector manufactured by Amphenol RF, designed to convert between SMA Jack (Female Socket) and N Jack (Female Socket) interfaces. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 11 GHz and supports operating temperatures from -65°C to 165°C.

The APH-SMAJ-NJ is classified as an obsolete product. Identifying equivalent substitute parts is necessary to ensure continued availability for maintenance, repair, and system integration where this adapter is specified in existing designs or installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APH-SMAJ-NJ is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Adapter Type: Jack to Jack
• Adapter Series: SMA to N
• Center Gender: Female to Female
• Convert From: SMA Jack, Female Socket
• Convert To: N Jack, Female Socket
• Impedance: 50 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded, Threaded
• Frequency - Max: 11 GHz
• Operating Temperature Range: -65°C ~ 165°C
• Body Material: Brass
• Body Finish: Nickel
• Center Contact Material: Phosphor Bronze
• Center Contact Plating: Gold
• Dielectric Material: Polytetrafluoroethylene (PTFE)

The substitute part 242115 meets all mandatory matching parameters and is therefore classified as a direct equivalent substitute for the obsolete APH-SMAJ-NJ.
