BNC Jack-to-Jack Coaxial Adapter 335R744 Equivalent & Substitute Parts

Part Overview

The Winchester Interconnect 335R744 is a coaxial connector adapter designed for RF applications requiring female BNC jack-to-female BNC jack conversion at 75 ohms impedance. This adapter facilitates connection between two BNC female socket connectors in a straight configuration with panel mount bulkhead installation.

The 335R744 is discontinued at DiGi Electronics. Identifying equivalent substitute parts ensures continued availability for maintenance, repair, and new system integration where this adapter specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 335R744 BNC coaxial adapter are identified based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Adapter Type: Jack to Jack
• Adapter Series: BNC to BNC
• Center Gender: Female to Female
• Impedance: 75 Ohms
• Style: Straight
• Mounting Type: Panel Mount with Bulkhead feature
• Fastening Type: Bayonet Lock
• Frequency - Max: 2 GHz or greater
• Center Contact Plating: Gold
• Body Material: Brass
• Body Finish: Nickel
• Center Contact Material: Phosphor Bronze

The substitute part Amphenol RF 112444 meets all mandatory matching parameters and is therefore classified as a direct functional equivalent for the discontinued 335R744.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol RF 112444 is the direct equivalent substitute for the discontinued Winchester Interconnect 335R744 BNC coaxial adapter.

Selection Basis:

All critical electrical and mechanical parameters match exactly between the two parts. Both adapters provide identical functional performance for BNC female-to-female jack conversion at 75 ohms impedance with 2 GHz maximum frequency operation.

The 112444 maintains active product status, ensuring continued availability and supply chain reliability. The part carries ROHS3 compliance, exceeding the RoHS compliance of the original 335R744. REACH compliance status is documented for the 112444, providing regulatory transparency for applications subject to REACH requirements.

Operating temperature range (-40°C ~ 85°C) is specified for the 112444, providing defined thermal performance boundaries for system integration.

Packaging format differs: the 335R744 packaging is unspecified, while the 112444 is supplied in bag packaging. This does not affect functional equivalence or installation compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 112444 directly replace the Winchester Interconnect 335R744 in existing installations?

A: Yes. The 112444 matches all critical parameters of the 335R744, including adapter type, impedance, connector gender configuration, mounting method, and frequency rating. Direct substitution is supported without modification to mechanical or electrical interfaces.

Q: What is the significance of the dielectric material specification in the 112444?

A: The 112444 specifies Polyoxymethylene (POM) Acetal as the dielectric material. This material provides defined electrical and mechanical properties for the adapter's internal structure. The original 335R744 does not specify dielectric material in available documentation. The POM Acetal specification in the 112444 represents standard material selection for this adapter class and does not affect compatibility.

Q: Are there differences in packaging between these two parts?

A: The 335R744 packaging type is not specified in available data. The 112444 is supplied in bag packaging. Both parts include identical component sets: 1 connector, 1 lockwasher, and 1 nut. Packaging format does not affect functional performance or installation compatibility.

Q: What compliance certifications apply to the 112444?

A: The 112444 carries ROHS3 compliance and is REACH Affected. Both certifications exceed or match the regulatory requirements of the original 335R744. These certifications confirm suitability for regulated markets and applications with environmental compliance requirements.

Q: Is the operating temperature range of the 112444 suitable for my application?

A: The 112444 operates across -40°C to 85°C. This range covers standard industrial and commercial RF applications. Verify that your specific application requirements fall within this temperature envelope. The original 335R744 does not specify operating temperature limits in available documentation.

Q: What is the inventory status of the substitute part?

A: The Amphenol RF 112444 is in active production with 1,338 pieces available in new original stock. The discontinued 335R744 has 798 pieces remaining in inventory. The 112444's active status ensures long-term availability for ongoing procurement needs.
