Amphenol RF 112122 BNC Connector Plug Equivalent & Substitute Parts

Part Overview

The Amphenol RF 112122 is a BNC connector plug designed for 50-ohm coaxial cable applications. This male pin connector features crimp termination for both center contact and shield, with a bayonet lock fastening mechanism. The connector is rated for operation up to 4 GHz and supports standard RG-series cable groups including RG-59, RG-62, and Belden variants. The 112122 maintains Active product status and is ROHS3 compliant, making it suitable for new design implementations. Equivalent substitute parts are identified for applications requiring alternative packaging configurations or where inventory constraints necessitate component alternatives.

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol RF 112122 is determined by strict equivalence across the following critical parameters:

Connector Style, Connector Type, Impedance, Contact Termination, Shield Termination, Mounting Type, Fastening Type, Frequency Maximum, Cable Group Compatibility, Voltage Rating, Mating Cycles, and Insertion Loss must remain identical across all substitute parts.

The identified substitute part 112118 maintains complete electrical and mechanical equivalence to the 112122 across all specified parameters. Both connectors are BNC male plug configurations with 50-ohm impedance, crimp termination for center contact and shield, bayonet lock fastening, and identical frequency, voltage, and performance ratings. The primary distinction between these parts is packaging configuration and product lifecycle status.

Engineering Selection Recommendations

The Amphenol RF 112122 is the primary selection for new design implementations due to its Active product status. This designation indicates full manufacturer support, ongoing production, and suitability for current and future applications.

The substitute part 112118 is electrically and mechanically equivalent across all specified parameters but carries a "Not For New Designs" product status. This classification indicates the part remains available for existing applications and legacy system support but is not recommended for incorporation into new product designs. The 112118 is appropriate for replacement, repair, and maintenance of existing installations where the original 112122 specification was previously established.

Both parts maintain identical ROHS3 compliance and REACH affected status, ensuring regulatory equivalence for applications subject to environmental and hazardous substance restrictions.

Frequently Asked Questions (FAQ)

Q: Can the 112118 substitute for the 112122 in new product designs?

A: No. The 112122 is designated Active and is the appropriate selection for new designs. The 112118 carries a "Not For New Designs" status and should be reserved for replacement and maintenance of existing systems.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Both connectors maintain identical impedance (50 ohms), frequency rating (4 GHz), voltage rating (500 V), mating cycles (500), and insertion loss (0.2 dB). They are electrically equivalent.

Q: Are the mechanical specifications identical between these two parts?

A: Yes. Both connectors feature identical BNC male plug configuration, crimp termination for center contact and shield, bayonet lock fastening, and free-hanging in-line mounting. They are mechanically equivalent.

Q: What is the difference between the 112122 and 112118?

A: The primary differences are packaging configuration and product lifecycle status. The 112122 is supplied without specified packaging and maintains Active status. The 112118 is supplied in bag packaging and carries "Not For New Designs" status.

Q: Are both parts compatible with the same cable types?

A: Yes. Both the 112122 and 112118 support identical cable group compatibility including RG-59, RG-59B, RG-62, RG-140, RG-210, and Belden variants 8241, 8263, 8279, and 9209.

Q: Do both parts meet the same compliance standards?

A: Yes. Both connectors are ROHS3 compliant and REACH affected, meeting identical environmental and regulatory requirements.

Q: Can I use the 112118 as a replacement for a failed 112122 in an existing installation?

A: Yes. The 112118 is electrically and mechanically equivalent and is appropriate for replacement and maintenance applications.
