Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 112740 are qualified based on strict electrical and mechanical parameter alignment. All substitute parts maintain identical specifications for the following critical parameters: BNC connector style, female socket jack type, 75 ohm impedance, board edge end launch mounting with panel mount configuration, solder contact and shield termination, bayonet lock fastening, 4 GHz maximum frequency, 500 volt rating, single port configuration, brass body with gold finish, gold-plated center contacts, and PTFE dielectric material. All substitutes include the same accessory package of connector, lockwasher, and nut.

The substitution logic is based on these key parameters:

• Electrical compatibility: 75 ohm impedance, 4 GHz frequency rating, 500 V voltage rating
• Mechanical compatibility: BNC jack female socket, board edge end launch, panel mount solder termination, bayonet lock fastening
• Material compatibility: Brass body, gold finish, PTFE dielectric, gold-plated center contacts
• Regulatory compliance: RoHS3 compliant, REACH affected, MSL 1

Amphenol RF 112740-12 is a parametric equivalent from the same manufacturer with identical electrical and mechanical specifications. Cinch Connectivity Solutions Trompeter UCBBJE20-1 and UCBBJE20-3 are parametric equivalents from an alternative manufacturer, maintaining all critical electrical and mechanical parameters while offering different packaging and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can Amphenol RF 112740-12 be used as a direct replacement for Amphenol RF 112740?

A: Yes. The 112740-12 maintains identical electrical and mechanical specifications including 75 ohm impedance, 4 GHz frequency rating, 500 volt rating, BNC jack female socket configuration, board edge end launch mounting, solder termination, and all material specifications. The parts are interchangeable.

Q: What is the difference between Amphenol RF 112740 and the Cinch Connectivity Solutions Trompeter UCBBJE20 series?

A: The primary difference is manufacturer. Both Amphenol RF 112740 and Cinch UCBBJE20-1 and UCBBJE20-3 maintain identical electrical specifications (75 ohm impedance, 4 GHz frequency, 500 volt rating) and mechanical configurations (BNC jack, board edge end launch, solder termination, bayonet lock fastening). All are RoHS3 compliant and REACH affected. The Cinch parts are suitable for direct substitution.

Q: Are there differences in operating temperature between the main part and substitutes?

A: The Amphenol RF 112740 does not specify an operating temperature range in the provided data. Amphenol RF 112740-12, Cinch UCBBJE20-1, and Cinch UCBBJE20-3 all specify an operating temperature range of -65°C to 165°C. This extended specification does not restrict substitution and indicates broader environmental capability.

Q: What packaging options are available?

A: Amphenol RF 112740 is supplied in standard packaging. Amphenol RF 112740-12, Cinch UCBBJE20-1, and Cinch UCBBJE20-3 are all supplied in bulk packaging. All parts include the same accessory package of one connector, one lockwasher, and one nut.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Amphenol RF 112740, Amphenol RF 112740-12, Cinch UCBBJE20-1, and Cinch UCBBJE20-3 are all RoHS3 compliant and REACH affected. All parts meet current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the maximum frequency rating for these connectors?

A: All parts in this equivalency group are rated for a maximum frequency of 4 GHz. This specification is consistent across Amphenol RF 112740, Amphenol RF 112740-12, Cinch UCBBJE20-1, and Cinch UCBBJE20-3.

Q: Can these connectors be used in 50 ohm applications?

A: No. All parts in this equivalency group are specified for 75 ohm impedance. They are not suitable for 50 ohm applications.
