Amphenol RF 031-6843 BNC Connector Equivalent & Substitute Parts

Part Overview

The Amphenol RF 031-6843 is an active BNC straight crimp jack connector designed for RF coaxial applications. This female socket connector operates at 50 ohms impedance and supports frequencies up to 4 GHz. The connector features panel mount installation with bulkhead front side nut fastening and bayonet lock mating. The 031-6843 is supplied in bulk packaging and includes five component pieces per connector unit. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when packaging requirements differ.

Parameter Comparison

Engineering Selection Recommendations

Both the 031-6843 and 112522 are active products from Amphenol RF with identical compliance certifications. Selection between these parts should be based on the following criteria:

Packaging Requirements: The 031-6843 is supplied in bulk packaging, while the 112522 is supplied in bag packaging. Choose based on inventory management and procurement workflow requirements.

Component Kit Composition: The 031-6843 includes five components per unit, while the 112522 includes six components per unit with an additional gasket. Verify that the included gasket in the 112522 is compatible with your assembly process if substituting.

Center Contact Material: The 031-6843 uses beryllium copper for the center contact, while the 112522 uses phosphor bronze. Both materials provide equivalent electrical performance at the specified 50-ohm impedance and 4 GHz frequency range.

Regulatory Compliance: Both parts are ROHS3 compliant and REACH affected, meeting current environmental and regulatory standards for electronic components.

Product Status: Both parts maintain active product status with current manufacturing support from Amphenol RF.

Frequently Asked Questions (FAQ)

Q: Can the 112522 be used as a direct replacement for the 031-6843 in existing designs?

A: Yes. Both connectors share identical electrical specifications (50 ohms, 4 GHz maximum frequency), mechanical mounting characteristics (panel mount, bulkhead front side nut), and cable compatibility (RG-178 series). The primary differences are packaging format and minor component kit variations.

Q: What is the difference between the center contact materials used in these connectors?

A: The 031-6843 uses beryllium copper while the 112522 uses phosphor bronze. Both materials provide equivalent electrical conductivity and performance at the specified operating parameters. Material selection does not affect RF performance or impedance characteristics.

Q: Does the additional gasket included in the 112522 affect compatibility?

A: The gasket is an additional component included in the 112522 kit. It does not affect electrical or mechanical compatibility. Verify that your assembly process can accommodate this additional component or exclude it if not required for your application.

Q: Are both parts suitable for the same cable types?

A: Yes. Both the 031-6843 and 112522 support crimp termination with the same cable group: RG-178, 178A, 178B, 196, 196A, and M17/93-RG178.

Q: What is the operating temperature range for these connectors?

A: The 031-6843 specifies an operating temperature range of -40°C to 85°C. Operating temperature data for the 112522 is not provided in the available specifications.

Q: Are both connectors RoHS and REACH compliant?
