Molex 0731000166 BNC Connector Jack Equivalent & Substitute Parts

Part Overview

The Molex 0731000166 is a BNC connector jack (female socket) rated for 50 ohms impedance, designed for panel mount through-hole applications with right-angle solder termination. This connector features bayonet lock fastening and is classified as Active product status with ROHS3 compliance. Substitute parts are identified when equivalent electrical specifications (50 ohm impedance, jack/female socket configuration, solder termination, right-angle mounting, through-hole installation) and mechanical compatibility parameters are met across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0731000166 are grouped based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Core Electrical Parameters (Non-Negotiable):

• Impedance: 50 Ohms
• Connector Type: Jack, Female Socket
• Contact Termination: Solder
• Shield Termination: Solder

Core Mechanical Parameters (Non-Negotiable):

• Connector Style: BNC
• Mounting Type: Panel Mount, Through Hole, Right Angle
• Fastening Type: Bayonet Lock
• Number of Ports: 1

Compliance Parameters:

• RoHS Status: ROHS3 or RoHS Compliant
• Product Status: Active

All substitute parts listed meet these criteria. Parts are sourced from Winchester Interconnect (364A595, 364A595BL, 364M595, 364M595L, 364M2595) and Cinch Connectivity Solutions Johnson (146-0701-301). The Winchester Interconnect variants (364 series) maintain identical BNC connector specifications with operational temperature range of -40°C to 165°C and 500V voltage rating. The Cinch part (146-0701-301) represents a different connector style (QMA) and is listed as a manufacturer-recommended alternative despite differing fastening mechanism (snap-on versus bayonet lock).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (BNC Connector Family):

Winchester Interconnect parts 364A595, 364A595BL, 364M595, and 364M595L are direct functional equivalents to the Molex 0731000166. All maintain BNC connector style, 50 ohm impedance, bayonet lock fastening, and identical mating cycle ratings. These parts carry RoHS compliance certification and Active product status. The 364A595 and 364A595BL variants are functionally identical with different packaging (tray format). The 364M595 and 364M595L variants differ only in body material composition (zinc versus zinc alloy) and are available in tray packaging. All Winchester variants support 4 GHz maximum frequency and 500V voltage rating with 0.2dB insertion loss specification.

Special Consideration (Multi-Port Configuration):

Winchester 364M2595 is a dual-port (2-port) variant of the BNC connector family. While it maintains all core electrical parameters (50 ohm impedance, BNC style, solder termination, bayonet lock), the dual-port configuration and reduced frequency rating (1 GHz maximum) distinguish it from single-port applications. This part is suitable only for applications requiring multiple BNC connections on a single connector body.

Alternative Connector Style (QMA):

Cinch Connectivity Solutions Johnson 146-0701-301 is listed as a manufacturer-recommended substitute despite representing a different connector style (QMA versus BNC). This part maintains 50 ohm impedance, jack/female socket configuration, solder termination, and through-hole right-angle mounting. However, the snap-on fastening mechanism differs from the bayonet lock specification of the Molex part. The Cinch part supports higher frequency operation (12.4 GHz maximum) and extended operating temperature range (-65°C to 165°C). Selection of this alternative requires confirmation that QMA connector compatibility is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can Winchester 364A595 directly replace Molex 0731000166 in my application?

A: Yes, for applications requiring BNC connector jack configuration with 50 ohm impedance, solder termination, panel mount through-hole right-angle installation, and bayonet lock fastening. Both parts meet identical electrical and mechanical specifications and carry active product status with RoHS compliance.

Q: What is the difference between Winchester 364M595 and 364M595L?

A: Both parts are functionally equivalent BNC connector jacks with identical electrical specifications. The primary difference is body material composition: 364M595 uses zinc body material while 364M595L uses zinc body material as well. Both are available in tray packaging and support 4 GHz frequency operation with 500V voltage rating.

Q: Why is the Cinch 146-0701-301 listed as a substitute if it uses QMA connector style instead of BNC?

A: The Cinch part is listed as a manufacturer-recommended alternative based on the input data provided. While it maintains core electrical parameters (50 ohm impedance, jack/female socket, solder termination), the QMA connector style and snap-on fastening mechanism represent a different physical interface. This part is suitable only if your application can accommodate QMA connector compatibility.

Q: Does Winchester 364M2595 work as a substitute for single-port applications?

A: Winchester 364M2595 is a dual-port connector variant. While it maintains BNC connector style and 50 ohm impedance specifications, the two-port configuration and 1 GHz frequency limitation make it unsuitable for applications designed for single-port BNC connectors. Use this part only for applications requiring multiple BNC connections on a single connector body.

Q: Are all substitute parts available in the same packaging format as the Molex original?

A: No. The Molex 0731000166 is supplied in bag packaging. Winchester Interconnect substitutes (364 series) are supplied in tray packaging. Cinch 146-0701-301 is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the inventory status of these substitute parts?

A: Based on provided data: Winchester 364A595 (1104 pcs), Winchester 364A595BL (6553 pcs), Winchester 364M595 (1434 pcs), Winchester 364M595L (1160 pcs), Winchester 364M2595 (4560 pcs), and Cinch 146-0701-301 (3815 pcs) are listed as new original in stock.
