Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2-227079-0 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: BNC
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Crimp
• Shield Termination: Crimp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Frequency - Max: 4 GHz
• Cable Group: RG-179, 187
• Operating Temperature: -55°C ~ 85°C
• Voltage Rating: 500 V
• Mating Cycles: 500

All identified substitute parts meet these mandatory parameters. Variations in body material, dielectric material, body finish, and RoHS compliance status do not prevent functional substitution when these core electrical and mechanical specifications are maintained.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 2-227079-2

The 2-227079-2 is the direct functional equivalent of the 2-227079-0. Both parts share identical electrical specifications, mechanical configuration, and material composition (brass body with nickel finish and polyethylene dielectric). The 2-227079-2 is currently in active product status with higher inventory availability (1064 units), making it the preferred choice for direct replacement in applications where the original part is no longer available.

Secondary Recommendation: 5225395-8

The 5225395-8 provides full electrical and mechanical compatibility with identical impedance, frequency response, and termination specifications. This part features a polytetrafluoroethylene (PTFE) dielectric instead of polyethylene, which offers improved high-frequency performance and temperature stability. The 5225395-8 is active in production with RoHS compliance and represents a suitable upgrade path for new designs or applications requiring enhanced dielectric properties.

Alternative Recommendation: CPM8820

The CPM8820 from Cinch Connectivity Solutions is an active, RoHS-compliant alternative manufactured by a different supplier. This part maintains all critical electrical and mechanical parameters and offers the highest inventory availability (2200 units). The CPM8820 is suitable for applications where multi-source qualification is required or where supply chain diversification is beneficial.

Consideration: 9-331350-3

The 9-331350-3 from TE Connectivity Aerospace, Defense and Marine division is discontinued at DiGi Electronics but remains functionally equivalent. This part features a silver body finish and PTFE dielectric. Selection of this part should be limited to legacy system maintenance where existing documentation specifies this variant.

Not Recommended for New Designs: 2-5221128-3 and 2-5227079-2

Both parts are classified as obsolete. While they maintain functional equivalence through identical electrical specifications, their obsolete status and zinc body material (versus brass in the original) make them unsuitable for new design implementations. These parts may be considered only for direct replacement in existing systems where supply is critical and no active alternatives are available.

Frequently Asked Questions (FAQ)

Q: Can the 2-227079-2 be used as a direct replacement for the 2-227079-0?

A: Yes. The 2-227079-2 is electrically and mechanically identical to the 2-227079-0. Both parts share the same impedance (50 ohms), frequency rating (4 GHz), termination method (crimp), and cable compatibility (RG-179, 187). The primary difference is product status: 2-227079-2 is active while 2-227079-0 is obsolete.

Q: What is the difference between the polyethylene and PTFE dielectric options?

A: Both dielectric materials meet the electrical specifications of this connector. Polyethylene (PE) is used in 2-227079-0, 2-227079-2, 2-5221128-3, and 2-5227079-2. Polytetrafluoroethylene (PTFE) is used in 5225395-8, 9-331350-3, and CPM8820. PTFE offers superior temperature stability and lower dielectric loss at higher frequencies, making it suitable for demanding applications. Both materials are compatible with the 50 ohm impedance and 4 GHz frequency specification.

Q: Are all substitute parts RoHS compliant?

A: No. The original 2-227079-0 is RoHS non-compliant. Among the substitutes, 2-5221128-3, 2-5227079-2, 5225395-8, 9-331350-3, and CPM8820 are RoHS compliant. The 2-227079-2 remains non-compliant, matching the original part's compliance status. Selection should be based on your application's regulatory requirements.

Q: What is the difference between the TE Connectivity AMP Connectors and TE Connectivity Aerospace, Defense and Marine variants?

A: The 9-331350-3 from the Aerospace, Defense and Marine division features a silver body finish and PTFE dielectric, whereas the standard AMP Connectors variants use nickel finish and polyethylene dielectric. Both maintain identical electrical performance and 50 ohm impedance. The aerospace variant is suitable for applications requiring enhanced corrosion resistance or specific military/aerospace specifications.

Q: Can I substitute the CPM8820 from Cinch for the TE Connectivity original?

A: Yes. The CPM8820 meets all mandatory electrical and mechanical parameters: 50 ohm impedance, BNC plug configuration, crimp termination, 4 GHz frequency rating, and compatibility with RG-179 and RG-187 cables. The CPM8820 is manufactured by a different supplier but provides full functional equivalence. This substitution is appropriate for applications requiring multi-source qualification or supply chain flexibility.

Q: Why are some substitute parts listed as obsolete?

A: Parts 2-5221128-3 and 2-5227079-2 are classified as obsolete by their manufacturers. While they remain functionally equivalent to the original 2-227079-0, their obsolete status indicates they are no longer in active production. These parts should be selected only when active alternatives are unavailable and legacy system support is required.

Q: What is the significance of the different body materials (brass versus zinc)?

A: The original 2-227079-0 uses a brass body with nickel finish. Substitutes 2-5221128-3 and 2-5227079-2 use zinc bodies with nickel finish. Both materials provide adequate shielding and mechanical strength for the 50 ohm BNC connector application. Material selection does not affect electrical performance or impedance matching. Brass bodies are generally preferred for corrosion resistance in long-term applications.

Q: Are the mating cycles and voltage ratings identical across all substitutes?

A: Yes. All substitute parts maintain 500 mating cycles and 500 V voltage rating, matching the original 2-227079-0 specification. These parameters are consistent across all identified equivalents and do not differentiate the substitution options.
