N Plug to BNC Plug Coaxial Adapter Connector 1303505

Part Overview

The Winchester Interconnect 1303505 is an active coaxial adapter connector designed to convert N Plug male pin connections to BNC Plug male pin connections. This adapter operates at 50 Ohms impedance and is configured for straight, free-hanging in-line mounting. The part is actively manufactured and maintained in inventory (1043 pieces in stock), making it suitable for RF applications requiring series conversion between N and BNC connector types.

Substitute parts become necessary when primary inventory is unavailable, when alternative packaging formats are required, or when application-specific performance parameters necessitate components with extended frequency or temperature operating ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1303505 is determined by strict adherence to the following core parameters:

Mandatory Matching Parameters:

• Adapter Type: Plug to Plug
• Adapter Series: BNC to N
• Center Gender: Male to Male
• Convert From: N Plug, Male Pin
• Convert To: BNC Plug, Male Pin
• Impedance: 50 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock, Threaded
• Body Material: Brass
• Body Finish: Nickel

Allowable Variation Parameters:

• Frequency - Max: May exceed 1 GHz
• Operating Temperature: May extend beyond -55°C ~ 100°C
• Center Contact Plating: May be specified (e.g., Gold)
• Center Contact Material: May be specified (e.g., Brass)
• Dielectric Material: May be specified (e.g., Polyoxymethylene)
• Packaging Format: May differ from original
• RoHS Compliance Level: May be ROHS3 Compliant (higher standard than RoHS Compliant)

The Amphenol RF 242122 qualifies as a substitute part because it maintains all mandatory matching parameters while offering enhanced frequency capability (4 GHz vs. 1 GHz) and gold-plated center contacts.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Winchester 1303505): Select the Winchester Interconnect 1303505 when the application operates within the specified frequency range of 1 GHz maximum and the operating temperature range of -55°C to 100°C is required. This part maintains active product status and RoHS Compliance certification. Current inventory availability is 1043 pieces.

Substitute Selection (Amphenol RF 242122): Select the Amphenol RF 242122 when the application requires extended frequency capability up to 4 GHz. This substitute maintains identical mechanical and electrical core specifications (50 Ohm impedance, plug-to-plug configuration, male-to-male center gender, straight style, free-hanging mounting, bayonet lock fastening). The 242122 provides gold-plated center contacts and specified dielectric material (Polyoxymethylene Acetal), which may improve contact reliability in certain RF environments. The 242122 carries ROHS3 Compliance certification, which represents a higher environmental standard than RoHS Compliance. Note that the operating temperature range is -40°C to 85°C, which is narrower than the 1303505. Current inventory availability is 849 pieces.

Both parts are active products with unlimited moisture sensitivity ratings (MSL 1) and are classified under ECCN EAR99 and HTSUS 8536.69.4010.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 242122 be used as a direct replacement for the Winchester 1303505?

A: Yes, the 242122 qualifies as a substitute for the 1303505 based on matching core adapter specifications. Both parts convert N Plug male connections to BNC Plug male connections at 50 Ohms impedance with identical mechanical configurations (straight, free-hanging, bayonet lock fastening). Verify that your application does not require the extended low-temperature capability of the 1303505 (-55°C minimum vs. -40°C minimum for the 242122).

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Frequency capability: 242122 supports 4 GHz versus 1303505 at 1 GHz; (2) Operating temperature range: 1303505 operates from -55°C to 100°C while 242122 operates from -40°C to 85°C; (3) Center contact specification: 242122 includes gold plating and brass material specification, while 1303505 does not specify these details; (4) Dielectric material: 242122 specifies Polyoxymethylene Acetal; (5) RoHS certification level: 242122 is ROHS3 Compliant versus RoHS Compliant for 1303505; (6) Packaging: 242122 is supplied in Bag format.

Q: Are both parts RoHS compliant?

A: Yes. The Winchester 1303505 is RoHS Compliant. The Amphenol RF 242122 is ROHS3 Compliant, which represents compliance with a more recent and stringent environmental standard. Both parts meet RoHS requirements.

Q: What is the impedance specification for both adapters?

A: Both the 1303505 and 242122 operate at 50 Ohms impedance, which is the standard impedance for RF coaxial connectors in these series.

Q: Can these adapters be used in high-frequency applications?

A: The Winchester 1303505 is rated to 1 GHz maximum frequency. The Amphenol RF 242122 is rated to 4 GHz maximum frequency. Select the 242122 for applications requiring frequencies above 1 GHz.

Q: What is the fastening mechanism for these adapters?

A: Both adapters use Bayonet Lock and Threaded fastening types, providing secure mechanical connection between the N Plug and BNC Plug interfaces.

Q: Are there any temperature limitations I should consider?

A: The Winchester 1303505 operates from -55°C to 100°C. The Amphenol RF 242122 operates from -40°C to 85°C. If your application requires operation below -40°C or above 85°C, the 1303505 is the appropriate selection.

Q: What materials are used in the construction of these adapters?

A: Both adapters feature brass bodies with nickel finish. The Amphenol RF 242122 additionally specifies brass center contact material with gold plating and Polyoxymethylene Acetal dielectric material.

Q: What is the moisture sensitivity level for these parts?

A: Both the 1303505 and 242122 carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
