Engineering Selection Recommendations
Amphenol RF 242104
The Amphenol RF 242104 serves as a direct functional equivalent to the Winchester Interconnect 3309505. Both components maintain identical adapter series conversion (BNC to SMA), center gender configuration (Male to Male), and impedance specification (50 Ohms). The Amphenol RF 242104 provides enhanced frequency capability at 4 GHz compared to the Winchester 1 GHz specification, and extends the operating temperature range to -65°C ~ 165°C. The component carries ROHS3 compliance certification and maintains active product status. This substitute is suitable for applications requiring equivalent or superior performance within the specified parameter envelope.
Pomona Electronics 4288
The Pomona Electronics 4288 maintains the same adapter series (BNC to SMA), center gender (Male to Male), and impedance (50 Ohms) as the Winchester Interconnect 3309505. However, the conversion direction is reversed: this component converts from SMA Plug to BNC Plug, whereas the Winchester converts from BNC Plug to SMA Plug. The Pomona Electronics 4288 offers significantly enhanced frequency capability at 12.4 GHz and extended operating temperature range to -65°C ~ 165°C. The component carries ROHS3 compliance and maintains active product status. This substitute is applicable only in applications where the reversed conversion direction is functionally acceptable.
Frequently Asked Questions (FAQ)
Q: Can the Amphenol RF 242104 be used as a direct replacement for the Winchester Interconnect 3309505?
A: Yes. Both components maintain identical adapter series conversion (BNC to SMA), center gender configuration (Male to Male), impedance (50 Ohms), style (Straight), mounting type (Free Hanging In-Line), and fastening type (Bayonet Lock, Threaded). The Amphenol RF 242104 provides enhanced frequency capability and extended operating temperature range.
Q: What is the key difference between the Amphenol RF 242104 and Pomona Electronics 4288?
A: The Amphenol RF 242104 converts from BNC Plug to SMA Plug, matching the Winchester Interconnect 3309505 conversion direction. The Pomona Electronics 4288 converts from SMA Plug to BNC Plug, which is the reverse direction. Both maintain 50 ohms impedance and identical mechanical interfaces.
Q: Can the Pomona Electronics 4288 be used in place of the Winchester Interconnect 3309505?
A: The Pomona Electronics 4288 is functionally compatible only if the application can accommodate the reversed conversion direction (SMA Plug to BNC Plug instead of BNC Plug to SMA Plug). All other electrical and mechanical parameters are compatible.
Q: What packaging formats are available for these adapters?
A: The Winchester Interconnect 3309505 is supplied without specified packaging. The Amphenol RF 242104 is packaged in Bag format. The Pomona Electronics 4288 is packaged in Bulk format.
Q: Are all three components RoHS compliant?
A: The Winchester Interconnect 3309505 carries RoHS Compliant status. Both the Amphenol RF 242104 and Pomona Electronics 4288 carry ROHS3 Compliant status, which represents a more recent compliance standard.
Q: What is the maximum frequency specification for each component?
A: The Winchester Interconnect 3309505 operates to 1 GHz maximum frequency. The Amphenol RF 242104 operates to 4 GHz maximum frequency. The Pomona Electronics 4288 operates to 12.4 GHz maximum frequency.
Q: What is the operating temperature range for each component?
A: The Winchester Interconnect 3309505 operates from -55°C to 100°C. Both the Amphenol RF 242104 and Pomona Electronics 4288 operate from -65°C to 165°C, providing extended temperature capability.
