Key Parameters

Substitute Part Grouping Explanation

The Amphenol RF 112235 qualifies as a direct substitute for the 456-218G based on the following critical parameters:

• Connector Style & Type: Both are BNC jack (female socket) connectors
• Impedance Rating: Both maintain 75-ohm impedance specification
• Termination Method: Both use crimp termination for contact and shield
• Mounting Configuration: Both feature panel mount with bulkhead front-side nut
• Fastening Mechanism: Both employ bayonet lock fastening
• Cable Compatibility: The 112235 supports RG-179 and extended cable variants (179A, 179B, 187, 187A, Belden 9221, M17/94-RG179), providing broader compatibility

The 112235 represents an active product with enhanced specifications and superior availability compared to the obsolete 456-218G.

Engineering Selection Recommendations

The Amphenol RF 112235 is the appropriate substitute for the obsolete 456-218G. Selection rationale:

• Product Status: The 112235 maintains active production status, ensuring long-term availability and supply chain continuity
• Functional Equivalence: All critical electrical and mechanical parameters align with the original specification
• Compliance Enhancement: The 112235 carries ROHS3 compliance and REACH affected status, meeting current regulatory requirements
• Performance Margin: The 112235 provides higher voltage rating (500 V vs. 200 V) and documented mating cycle capability (500 cycles), offering improved reliability margins
• Inventory Availability: 2417 units in stock versus 691 units for the obsolete part

Frequently Asked Questions (FAQ)

Q: Can the 112235 directly replace the 456-218G in existing designs?

A: Yes. Both connectors share identical BNC jack configuration, 75-ohm impedance, crimp termination, panel mount bulkhead installation, and bayonet fastening. Physical and electrical compatibility is confirmed.

Q: What cable types are compatible with the 112235?

A: The 112235 supports RG-179, RG-179A, RG-179B, RG-187, RG-187A, Belden 9221, and M17/94-RG179 cables. The original 456-218G specification lists RG-179 compatibility; the 112235 extends this range.

Q: Are there compliance differences between the two parts?

A: The 456-218G is RoHS Compliant. The 112235 is ROHS3 Compliant and REACH Affected, reflecting current environmental and chemical safety standards.

Q: What is the voltage rating difference, and does it matter for my application?

A: The 456-218G is rated 200 V; the 112235 is rated 500 V. If your application operates below 200 V, both are suitable. If operation approaches or exceeds 200 V, the 112235 provides additional safety margin.

Q: Does the 112235 include termination components?

A: Yes. The 112235 includes 7 pieces: 1 connector, 1 contact, 1 ferrule, 1 gasket, 1 lockwasher, 1 nut, and 1 sleeve. Verify that your assembly process accommodates these included components.

Q: What is the packaging difference?

A: The 456-218G packaging is not specified. The 112235 is supplied in bag packaging. Confirm packaging requirements for your procurement and assembly workflow.
