Amphenol RF 112721 BNC Connector Plug 75 Ohm Equivalent & Substitute Parts

Part Overview

The Amphenol RF 112721 is an active BNC connector plug designed for 75 ohm coaxial cable applications. This male pin connector features crimp or solder termination with a bayonet lock fastening mechanism, suitable for free hanging (in-line) installations. The connector operates at frequencies up to 4 GHz and is rated for 500 volts with 500 mating cycles. As an active product with ROHS3 compliance and REACH affected status, equivalent substitute parts from alternative manufacturers are available to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 112721 are qualified based on electrical and mechanical parameter equivalence within the BNC connector plug category. The substitution criteria are:

Electrical Parameters:

• Impedance: 75 Ohms (exact match required)
• Frequency - Max: 4 GHz (minimum requirement)
• Voltage Rating: 500 V (minimum requirement)

Mechanical Parameters:

• Connector Style: BNC (exact match required)
• Connector Type: Plug, Male Pin (exact match required)
• Contact Termination: Crimp (primary termination method)
• Shield Termination: Crimp (exact match required)
• Mounting Type: Free Hanging (In-Line) (exact match required)
• Fastening Type: Bayonet Lock (exact match required)

Material & Construction Parameters:

• Body Material: Brass (exact match required)
• Body Finish: Nickel (exact match required)
• Center Contact Material: Brass (exact match required)
• Center Contact Plating: Gold (exact match required)
• Dielectric Material: PTFE (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (required)
• REACH Status: REACH Affected (required)

All three substitute parts (UPL220-009, UPL220-025, UPL220-026) from Cinch Connectivity Solutions Trompeter meet these criteria and are functionally equivalent to the Amphenol RF 112721.

Parameter Comparison

Engineering Selection Recommendations

All three Cinch Connectivity Solutions Trompeter substitute parts (UPL220-009, UPL220-025, UPL220-026) are functionally equivalent to the Amphenol RF 112721 for applications requiring 75 ohm BNC connector plugs with crimp termination.

Compliance & Regulatory Status: All substitute parts maintain ROHS3 compliance and REACH affected status, consistent with the original part. All parts carry EAR99 export classification and 8536.69.4010 HTSUS code. Moisture sensitivity level remains at MSL 1 (Unlimited) across all options.

Product Status: The Amphenol RF 112721 and all three substitute parts are active products with current inventory availability. The Amphenol RF 112721 has 1074 pieces in stock, while substitute inventory levels are: UPL220-009 (1162 pieces), UPL220-025 (914 pieces), and UPL220-026 (1153 pieces).

Electrical & Mechanical Equivalence: All substitute parts match the primary electrical specifications (75 ohms, 4 GHz maximum frequency, 500 V rating) and mechanical configuration (BNC plug, male pin, bayonet lock, free hanging in-line mounting). Material composition and plating specifications are identical across all options.

Cable Group Compatibility: Substitute parts are qualified for specific cable groups: UPL220-009 supports Belden 8218, YR23023, and Essex 21-597; UPL220-025 supports 734A; UPL220-026 supports 735A. Cable group compatibility should be verified against application requirements.

Frequently Asked Questions (FAQ)

Q: Are the Cinch UPL220 series connectors direct replacements for the Amphenol RF 112721?

A: The Cinch UPL220-009, UPL220-025, and UPL220-026 are functionally equivalent substitutes. All three parts match the electrical specifications (75 ohms, 4 GHz, 500 V), mechanical configuration (BNC plug, male pin, bayonet lock, free hanging mounting), and material composition (brass body with nickel finish, gold-plated brass center contact, PTFE dielectric). Compliance certifications (ROHS3, REACH) are identical.

Q: What is the difference between the three Cinch substitute parts?

A: The three Cinch substitute parts (UPL220-009, UPL220-025, UPL220-026) are electrically and mechanically identical. The primary difference is cable group compatibility: UPL220-009 is qualified for Belden 8218, YR23023, and Essex 21-597 cables; UPL220-025 is qualified for 734A cable; UPL220-026 is qualified for 735A cable. Selection should be based on the specific cable type used in the application.

Q: Does the Amphenol RF 112721 support solder termination while the Cinch substitutes only support crimp?

A: The Amphenol RF 112721 specification lists "Crimp or Solder" contact termination, while the Cinch UPL220 series specifies crimp termination only. For applications requiring solder termination, the Amphenol RF 112721 is the appropriate choice. For crimp termination applications, all four parts are equivalent.

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

A: The Amphenol RF 112721 does not specify an operating temperature range in the provided data. The Cinch UPL220 series specifies -65°C to 165°C operating temperature. For applications with specific temperature requirements, the Cinch parts provide documented thermal performance.

Q: Are there any differences in packaging between the main part and substitutes?

A: The Amphenol RF 112721 packaging is not specified in the provided data. The Cinch UPL220 series parts are supplied in bulk packaging. The Amphenol RF 112721 includes 5 pieces per package (1 connector, 1 contact, 1 ferrule, 1 insulator, 1 sleeve), while Cinch UPL220 parts include 2 pieces per package (1 connector, 1 contact). Packaging quantity differences should be considered for procurement planning.

Q: Are all parts RoHS and REACH compliant?

A: All four parts (Amphenol RF 112721 and the three Cinch UPL220 variants) are ROHS3 compliant and REACH affected. All carry EAR99 export classification and 8536.69.4010 HTSUS code. Moisture sensitivity level is MSL 1 (Unlimited) for all parts.

Q: What mating cycle ratings apply to these connectors?

A: The Amphenol RF 112721 specifies 500 mating cycles. The Cinch UPL220 series does not provide mating cycle data in the available specifications. For applications with high mating cycle requirements, the Amphenol RF 112721 documented rating should be referenced.
