BNC Jack-to-Jack Coaxial Adapter 75 Ohm (335A744)

Part Overview

The Winchester Interconnect 335A744 is an active coaxial connector adapter designed for RF applications requiring female-to-female BNC jack connections at 75 ohm impedance. This adapter facilitates connection between two BNC jack connectors in a straight configuration with panel mount bulkhead installation. The part is actively manufactured and stocked, with 1163 units available in inventory. Alternative equivalent parts may be required due to supply chain considerations, manufacturing lead times, or specific procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 335A744 is determined by 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 Maximum: 2 GHz or greater
• Center Contact Plating: Gold
• Body Material: Brass
• Body Finish: Nickel
• Center Contact Material: Phosphor Bronze

The substitute part Amphenol RF 112438 meets all mandatory matching parameters and qualifies as a direct equivalent. Both parts are active products with current manufacturing status and identical electrical and mechanical specifications within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the Winchester Interconnect 335A744 and Amphenol RF 112438 are qualified equivalents for BNC jack-to-jack 75 ohm coaxial adapter applications. Selection between these parts should be based on the following engineering and compliance factors:

Winchester Interconnect 335A744:

• Active product status with 1163 units in current inventory
• RoHS Compliant certification
• Established supply availability

Amphenol RF 112438:

• Active product status with 2474 units in current inventory
• ROHS3 Compliant certification (enhanced compliance standard)
• REACH Affected designation
• Operating temperature range specified: -40°C to 85°C
• Dielectric material specified: Polyoxymethylene (POM) Acetal
• Packaged in Bag format

Both parts satisfy identical electrical and mechanical requirements. The Amphenol RF 112438 provides additional technical documentation including operating temperature range and dielectric material specification. Selection may be influenced by inventory availability, packaging requirements, or specific compliance documentation needs for end-use applications.

Frequently Asked Questions (FAQ)

Q: Can Amphenol RF 112438 directly replace Winchester Interconnect 335A744 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters: BNC jack-to-jack configuration, 75 ohm impedance, female-to-female center gender, straight style, panel mount bulkhead installation, bayonet lock fastening, 2 GHz frequency rating, gold-plated center contacts, brass body with nickel finish, and phosphor bronze center contacts.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution requires equivalence in adapter type (jack-to-jack), adapter series (BNC-to-BNC), center gender (female-to-female), impedance (75 ohms), style (straight), mounting type (panel mount bulkhead), fastening type (bayonet lock), frequency rating (2 GHz minimum), contact plating (gold), body material (brass), body finish (nickel), and center contact material (phosphor bronze).

Q: Are there differences in compliance certifications between these parts?

A: The Winchester 335A744 carries RoHS Compliant certification. The Amphenol RF 112438 carries ROHS3 Compliant certification, which represents an enhanced compliance standard. Both parts meet RoHS requirements. The Amphenol part is additionally designated as REACH Affected.
