Amphenol RF 000-4525 BNC Jack-to-Jack Coaxial Adapter Equivalent & Substitute Parts

Part Overview

The Amphenol RF 000-4525 is an active, in-stock coaxial connector adapter designed for RF applications requiring female-to-female BNC jack connections at 50 ohms impedance. This straight-mount, panel-mount adapter with bayonet locking mechanism serves applications where two BNC female connectors must be joined in a single assembly. The part is RoHS3 compliant and operates across the temperature range of -65°C to 165°C. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the adapter interface, connector gender configuration, and impedance specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol RF 000-4525 is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Adapter configuration: Jack-to-Jack (female-to-female center contact)
• Connector series: BNC to BNC
• Impedance: 50 Ohms
• Fastening mechanism: Bayonet Lock

Critical Mechanical Parameters:

• Mounting style: Straight, panel-mount (bulkhead)
• Packaging configuration: Bulk with lockwasher and nut included
• Gender configuration: Female socket on both ends

Acceptable Variations:

• Dielectric material (PTFE or PE) provided impedance remains 50 Ohms
• Center contact plating (Silver or Gold)
• Body material and finish (Brass/Nickel or Zinc/Nickel)
• Center contact material (Beryllium Copper or Phosphor Bronze)
• Mating cycle rating (500 or higher)

Non-Substitutable Differences:

• Adapter type (must remain Jack-to-Jack)
• Impedance (must remain 50 Ohms)
• Connector series (must remain BNC)
• Mounting configuration (must remain panel-mount, straight)

Engineering Selection Recommendations

Primary Selection: Amphenol RF 000-4525

Select the Amphenol RF 000-4525 when RoHS3 compliance is a mandatory requirement. This part meets ROHS3 Compliant status and is suitable for applications subject to EU environmental regulations or customer specifications requiring RoHS certification. The part carries a specified operating temperature range of -65°C to 165°C and 500 mating cycles, providing defined performance boundaries for design validation.

Alternative Selection: TE Connectivity 228226-1

The TE Connectivity 228226-1 serves as a functional equivalent when RoHS compliance is not required and the application does not mandate the specified temperature or mating cycle ratings of the Amphenol part. Both parts maintain identical electrical and mechanical interface specifications: 50-ohm impedance, BNC jack-to-jack female-to-female configuration, straight panel-mount with bayonet locking. The TE Connectivity part includes gold-plated center contacts and phosphor bronze contact material, which may provide enhanced corrosion resistance in certain environments compared to the silver-plated beryllium copper contacts of the Amphenol part.

Compliance Consideration:

The Amphenol RF 000-4525 is RoHS3 compliant; the TE Connectivity 228226-1 is RoHS non-compliant. This distinction is critical for applications in regulated industries or where customer specifications mandate RoHS certification. Both parts are REACH Affected and carry EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 228226-1 be used as a direct replacement for the Amphenol RF 000-4525?

A: The TE Connectivity 228226-1 is electrically and mechanically equivalent in terms of adapter function, impedance, connector type, and mounting configuration. However, the Amphenol part is RoHS3 compliant while the TE Connectivity part is RoHS non-compliant. Selection depends on whether RoHS compliance is required by your application or customer specification.

Q: What are the critical parameters that must match for substitution?

A: The following parameters must remain identical: adapter type (Jack-to-Jack), connector series (BNC-to-BNC), center gender configuration (Female-to-Female), impedance (50 Ohms), mounting style (straight panel-mount with bulkhead), and fastening mechanism (bayonet lock). Variations in dielectric material, contact plating, body material, and contact material are acceptable provided impedance and electrical performance are maintained.

Q: Does the difference in dielectric material (PTFE vs. PE) affect substitution eligibility?

A: Both PTFE and PE dielectric materials are acceptable for 50-ohm BNC adapters. The material difference does not prevent substitution provided impedance specification is maintained at 50 Ohms. Material selection may be driven by specific environmental or frequency requirements not specified in the provided parameters.

Q: Are the mating cycle ratings interchangeable?

A: The Amphenol RF 000-4525 specifies 500 mating cycles. The TE Connectivity 228226-1 does not provide a mating cycle specification. If your application requires a defined mating cycle rating, the Amphenol part provides explicit specification. If mating cycle rating is not a design constraint, the TE Connectivity part may be used.

Q: What is the significance of the gold-plated vs. silver-plated center contacts?

A: Both gold and silver plating are acceptable for RF coaxial connectors. Gold plating typically provides enhanced corrosion resistance and is often preferred in high-reliability or harsh-environment applications. Silver plating is standard for general RF applications. The choice between these finishes depends on environmental exposure and reliability requirements not specified in the provided parameters.

Q: Can these adapters be used interchangeably in the same assembly?

A: Yes, provided the assembly does not have RoHS compliance requirements. Both adapters maintain identical BNC jack-to-jack female-to-female configuration, 50-ohm impedance, straight panel-mount style, and bayonet locking mechanism. The packaging includes identical components: connector, lockwasher, and nut.

Q: What is the difference in body material between the two parts?

A: The Amphenol RF 000-4525 uses brass body material with nickel finish. The TE Connectivity 228226-1 uses zinc body material with nickel finish. Both materials with nickel finish provide adequate shielding and environmental protection for RF coaxial adapters. Material selection does not affect electrical performance or substitution eligibility.
