Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 310A205F are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters for Substitution:

• Connector Style: BNC
• Connector Type: Plug, Male Pin
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Number of Ports: 1
• Shield Termination: Crimp

Impedance Classification:

The 310A205F operates at 50 ohms impedance. Substitute parts must maintain this impedance specification to ensure proper signal transmission and return loss characteristics in RF applications.

Pomona Electronics 5285 qualifies as a direct electrical substitute, maintaining 50-ohm impedance, BNC plug configuration, and crimp or solder termination capability. This part supports an extended cable group range (RG-58, RG-58A, RG-58C, RG-141, RG-141A) and operates at the same maximum frequency of 4 GHz.

Cinch Connectivity Solutions VB10-2061 is listed as a substitute but operates at 75-ohm impedance with reduced maximum frequency (1 GHz) and supports different cable groups (RG-179, RG-187). This part is not electrically equivalent for 50-ohm applications and represents a non-interchangeable alternative for distinct application requirements.

Parameter Comparison

Engineering Selection Recommendations

Pomona Electronics 5285 for 50-Ohm Applications:

The Pomona Electronics 5285 is the direct electrical equivalent for the Winchester Interconnect 310A205F in 50-ohm RF coaxial systems. Both components maintain identical impedance, maximum frequency rating (4 GHz), voltage rating (500 V), and mounting configuration. The 5285 supports an expanded cable group compatibility range including RG-58, RG-58A, RG-58C, RG-141, and RG-141A. Both parts are active products with current manufacturing status and comply with RoHS regulations. The 5285 carries ROHS3 compliance certification, representing the latest regulatory standard. Selection of the 5285 is appropriate when Winchester Interconnect 310A205F inventory is unavailable and 50-ohm impedance is required.

Cinch Connectivity Solutions VB10-2061 for 75-Ohm Applications:

The Cinch Connectivity Solutions VB10-2061 is not electrically equivalent to the 310A205F due to its 75-ohm impedance specification. This part operates at reduced maximum frequency (1 GHz versus 4 GHz) and supports different cable groups (RG-179, RG-187). The VB10-2061 is suitable only for applications specifically requiring 75-ohm impedance characteristics and operating frequencies below 1 GHz. This part is not a substitute for 50-ohm system applications.

Compliance and Regulatory Status:

All three components are active products with current manufacturing support. The Winchester Interconnect 310A205F and Cinch Connectivity Solutions VB10-2061 are RoHS Compliant. The Pomona Electronics 5285 carries ROHS3 Compliant certification. All parts are classified under ECCN EAR99 and HTSUS 8536.69.4010.

Frequently Asked Questions (FAQ)

Q: Can the Pomona Electronics 5285 replace the Winchester Interconnect 310A205F in existing designs?

A: Yes, the Pomona Electronics 5285 is electrically and mechanically equivalent for 50-ohm RF applications. Both components maintain identical impedance (50 ohms), maximum frequency (4 GHz), voltage rating (500 V), and mounting configuration (free-hanging in-line with bayonet lock fastening). The 5285 supports the same cable groups as the 310A205F plus additional compatibility with RG-58 and RG-141A.

Q: What is the primary difference between the 310A205F and the VB10-2061?

A: The primary difference is impedance specification. The 310A205F operates at 50 ohms, while the VB10-2061 operates at 75 ohms. Additionally, the VB10-2061 has a maximum frequency rating of 1 GHz compared to 4 GHz for the 310A205F. These differences make the VB10-2061 unsuitable for 50-ohm system applications.

Q: Are there cable group compatibility differences between the 310A205F and the 5285?

A: The Winchester Interconnect 310A205F supports RG-58A, RG-58C, and RG-141 cable groups. The Pomona Electronics 5285 supports RG-58, RG-58A, RG-58C, RG-141, and RG-141A. The 5285 provides expanded cable group compatibility while maintaining full compatibility with all cables supported by the 310A205F.

Q: What is the difference in center contact plating between the 310A205F and the 5285?

A: The Winchester Interconnect 310A205F features nickel center contact plating. The Pomona Electronics 5285 features gold center contact plating. Both plating materials are suitable for RF connector applications and do not affect electrical equivalence for impedance-matched systems.

Q: Can the VB10-2061 be used in applications designed for the 310A205F?

A: No. The VB10-2061 operates at 75-ohm impedance and is designed for different cable groups (RG-179, RG-187). Using the VB10-2061 in a 50-ohm system would result in impedance mismatch, signal reflections, and degraded system performance. The VB10-2061 is suitable only for applications specifically designed for 75-ohm impedance.

Q: What is the inventory status for these components?

A: The Winchester Interconnect 310A205F has 798 pieces in stock. The Pomona Electronics 5285 has 647 pieces in stock. The Cinch Connectivity Solutions VB10-2061 has 1266 pieces in stock. All components are listed as active products with current manufacturing support.

Q: Are all three components RoHS compliant?

A: Yes. The Winchester Interconnect 310A205F is RoHS Compliant. The Pomona Electronics 5285 is ROHS3 Compliant. The Cinch Connectivity Solutions VB10-2061 is RoHS Compliant. All components meet current environmental and regulatory requirements.
