Frequently Asked Questions (FAQ)

Q: Can the Winchester Interconnect 364A795BL directly replace the Amphenol RF 031-71052 in existing PCB designs?

A: Yes. Both connectors share identical electrical specifications (75-ohm impedance, 1 GHz maximum frequency, 0.2 dB insertion loss), mechanical mounting configuration (panel mount, through-hole, right-angle), and termination method (solder). PCB footprints and mounting hole patterns are compatible.

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

A: The primary differences are packaging format (Bulk versus Tray), operating temperature range (-55°C to 85°C versus -40°C to 165°C), body material (Zinc Die Cast versus Brass), and additional features (Winchester part includes Isolated feature and Weatherproof ingress protection). Electrical and mechanical performance are identical.

Q: Which part should be selected for high-temperature applications?

A: The Winchester Interconnect 364A795BL is rated for operation up to 165°C, compared to 85°C for the Amphenol RF part. For applications requiring extended high-temperature performance, the Winchester part is the appropriate selection.

Q: Are both parts RoHS compliant?

A: Yes. The Amphenol RF 031-71052 is ROHS3 Compliant. The Winchester Interconnect 364A795BL is RoHS Compliant. Both meet regulatory requirements for lead-free manufacturing.

Q: What is the significance of the Isolated feature on the Winchester part?

A: The Isolated feature on the Winchester Interconnect 364A795BL provides electrical isolation of the connector body from the PCB ground plane, which can be beneficial in applications requiring galvanic isolation or reduced ground loop coupling.

Q: Can these connectors be used interchangeably in production?

A: Yes, provided that the application requirements fall within the operating parameters of both parts. The Winchester Interconnect 364A795BL is suitable for all applications where the Amphenol RF 031-71052 is specified, with the additional capability for higher temperature environments.

Q: What packaging considerations apply when switching between these parts?

A: The Amphenol RF 031-71052 is supplied in Bulk packaging, while the Winchester Interconnect 364A795BL is supplied in Tray packaging. Bulk packaging typically requires manual handling and counting, while Tray packaging facilitates automated assembly processes. Procurement and inventory management procedures may require adjustment based on packaging format selection.
