Winchester Interconnect 5319505 Coaxial Adapter Connector

Part Overview

The Winchester Interconnect 5319505 is an RF coaxial adapter connector designed to convert between TNC and SMA connector series. This adapter features a TNC plug (male pin) on one end and an SMA jack (female socket) on the opposite end, maintaining 50-ohm impedance throughout the signal path. The connector operates across a frequency range up to 1 GHz and is rated for operating temperatures between -55°C and 100°C. The part is currently in active production status with 1,098 units available in inventory. Equivalent and substitute parts are identified when they maintain identical electrical specifications, mechanical compatibility, and functional performance characteristics within the same coaxial connector category.

Substitute Part Grouping Explanation

Substitute parts for the Winchester Interconnect 5319505 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Critical Matching Parameters:

Adapter type: Plug to Jack configuration
Conversion type: Between Series (SMA to TNC)
Connector gender configuration: TNC Plug (Male Pin) to SMA Jack (Female Socket)
Impedance: 50 Ohms
Style: Straight orientation
Mounting type: Free Hanging (In-Line)
Fastening type: Threaded connections on both ends

Identified Substitutes:

The Amphenol RF 242105 maintains all critical electrical and mechanical parameters identical to the main part. This adapter provides equivalent functionality with TNC plug to SMA jack conversion at 50-ohm impedance in a straight, free-hanging configuration.

The Pomona Electronics 4293 provides functional equivalence with reversed connector orientation (SMA jack to TNC plug conversion). While the connector ends are reversed relative to the main part, the electrical characteristics and mechanical mounting remain compatible for applications requiring this specific orientation.

Engineering Selection Recommendations

Amphenol RF 242105 Selection Criteria:

The Amphenol RF 242105 is a direct functional equivalent to the Winchester Interconnect 5319505. Both parts maintain identical connector configurations (TNC plug to SMA jack), impedance (50 ohms), and mechanical mounting specifications. The Amphenol part carries ROHS3 compliance certification, which exceeds the RoHS compliance of the main part. The maximum frequency rating of 11 GHz on the Amphenol part exceeds the 1 GHz specification of the Winchester part, providing additional operational headroom. The extended operating temperature range (-65°C to 165°C) of the Amphenol part encompasses the Winchester operating range (-55°C to 100°C). This part is suitable for direct substitution in applications where the Winchester 5319505 is specified.

Pomona Electronics 4293 Selection Criteria:

The Pomona Electronics 4293 provides equivalent electrical performance with reversed connector orientation. This part converts from SMA jack to TNC plug, opposite to the main part's TNC plug to SMA jack configuration. The Pomona part is suitable for applications requiring the reversed connector orientation while maintaining 50-ohm impedance and identical mechanical mounting characteristics. The maximum frequency rating of 12.4 GHz and extended operating temperature range (-65°C to 165°C) provide performance margins beyond the main part specifications. The Pomona part carries REACH Unaffected status and is not subject to RoHS requirements.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 242105 be used as a direct replacement for the Winchester Interconnect 5319505?

A: Yes. Both parts maintain identical connector configurations (TNC plug to SMA jack), 50-ohm impedance, straight orientation, and free-hanging in-line mounting. The Amphenol part meets or exceeds all electrical and mechanical specifications of the Winchester part.

Q: What is the functional difference between the Amphenol RF 242105 and the Pomona Electronics 4293?

A: The Amphenol RF 242105 converts TNC plug to SMA jack, matching the Winchester 5319505 configuration. The Pomona Electronics 4293 converts SMA jack to TNC plug, providing reversed connector orientation. Both maintain 50-ohm impedance and identical mechanical mounting.
