Key Parameters

Substitute Part Grouping Explanation

The substitute part 1-1337548-0 (TE Connectivity AMP Connectors) qualifies as an equivalent based on the following matching parameters:

• Connector style: BNC
• Connector type: Jack, Female Socket
• Impedance: 50 Ohms
• Mounting type: Panel Mount with Bulkhead - Front Side Nut configuration
• Fastening type: Bayonet Lock
• Maximum frequency: 4 GHz
• Voltage rating: 500 V
• Operating temperature range: -65°C ~ 165°C
• Insertion loss: 0.2 dB
• Mating cycles: 500
• Body material: Brass with Nickel finish
• Center contact plating: Gold
• Dielectric material: PTFE

The primary difference between these parts is the contact termination method: VB40-2071 uses crimp termination while 1-1337548-0 uses solder termination. Both termination methods are standard for BNC connectors and do not affect electrical performance when properly executed. The substitute part supports an expanded cable group range (RG-174A, 188A, 316 versus RG-174) and includes additional components in its package.
