Amphenol RF 000-2900 BNC to UHF Coaxial Adapter Connector

Part Overview

The Amphenol RF 000-2900 is an active coaxial adapter connector that converts between BNC Plug (Male Pin) and UHF Jack (Female Socket) configurations. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 4 GHz and is designed for free-hanging, in-line mounting applications. The connector utilizes bayonet lock and threaded fastening mechanisms to ensure secure mating. Identification of equivalent substitute parts becomes necessary when primary inventory is unavailable, when specific material compositions are required for application compatibility, or when alternative sourcing is needed to maintain supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 000-2900 and Pomona Electronics 3287 are active products with ROHS3 compliance and identical operating temperature specifications. Selection between these parts is based on the following engineering considerations:

Amphenol RF 000-2900 Selection Criteria:

• Applications requiring constant 50 Ohm impedance specification
• Systems where silver-plated center contacts are specified
• Installations where brass center contact material is required

Pomona Electronics 3287 Selection Criteria:

• Applications where non-constant impedance is acceptable
• Systems benefiting from gold-plated center contacts for enhanced corrosion resistance
• Installations where phosphor bronze center contact material provides improved durability
• Applications utilizing PTFE dielectric material for enhanced electrical performance

Both parts maintain identical mechanical compatibility, fastening mechanisms, and thermal operating ranges. The choice between these substitutes depends on the specific electrical and material requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the Pomona Electronics 3287 be used as a direct replacement for the Amphenol RF 000-2900?

A: The Pomona Electronics 3287 is mechanically and functionally compatible as a substitute. Both adapters feature identical BNC Plug to UHF Jack conversion, straight orientation, free-hanging mounting, and bayonet lock/threaded fastening. The primary difference is impedance specification: the 000-2900 is rated at 50 Ohms, while the 3287 is rated as Non-Constant impedance. Substitution is valid when non-constant impedance is acceptable for the application.

Q: What are the key differences between these two coaxial adapters?

A: The Amphenol RF 000-2900 and Pomona Electronics 3287 differ in four parameters: impedance rating (50 Ohms versus Non-Constant), center contact plating (Silver versus Gold), center contact material (Brass versus Phosphor Bronze), and dielectric material specification (not specified versus PTFE). All other parameters, including adapter type, conversion series, mounting configuration, and operating temperature range, are identical.

Q: Are both parts RoHS compliant?

A: Yes, both the Amphenol RF 000-2900 and Pomona Electronics 3287 are ROHS3 compliant and suitable for applications requiring RoHS certification.

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

A: Both adapters operate across an identical temperature range of -55°C to 85°C, ensuring compatibility in thermal environments.

Q: Does impedance difference affect mechanical compatibility?

A: No. Impedance specification does not affect mechanical compatibility. Both adapters feature identical physical dimensions, fastening mechanisms, and mating configurations. Impedance differences are electrical characteristics that affect signal transmission properties, not mechanical fit.

Q: What packaging is available for these parts?

A: Both the Amphenol RF 000-2900 and Pomona Electronics 3287 are supplied in bulk packaging.

Q: Which part should be selected for 50 Ohm impedance-critical applications?

A: The Amphenol RF 000-2900 is specified for 50 Ohm impedance and is the appropriate selection for applications requiring constant impedance matching at this specification.
