TE Connectivity AMP Connectors 227079-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 227079-6 is a BNC connector plug with straight male pin configuration, designed for 50 ohm coaxial cable applications. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing system support and new procurement requirements. The connector features crimp termination for both center contact and shield, operates across -55°C to 85°C, and supports frequencies up to 4 GHz with a maximum voltage rating of 500 V.

Substitute Part Grouping Explanation

Substitution of the 227079-6 is determined by strict equivalence across the following critical parameters: BNC connector style, male pin plug type, 50 ohm impedance, crimp termination for both center contact and shield, free hanging in-line mounting, bayonet lock fastening, 4 GHz maximum frequency, 500 V voltage rating, and 0.2 dB insertion loss. Cable group compatibility is a secondary consideration, as the connector must accommodate the same or broader cable specifications. Dielectric material differences (polyethylene versus polytetrafluoroethylene) do not preclude substitution when all primary electrical and mechanical parameters align. Parts are classified as parametric equivalents when all core specifications match; direct manufacturer alternatives when produced by different manufacturers with identical performance; and similar parts when cable group compatibility differs but core RF characteristics remain equivalent.

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity AMP Connectors 5227079-6

The 5227079-6 is the preferred direct replacement for the obsolete 227079-6. Both parts are manufactured by TE Connectivity AMP Connectors and share identical electrical and mechanical specifications across all critical parameters. The 5227079-6 maintains active product status and carries RoHS compliance certification, addressing regulatory requirements for new designs. Inventory availability is substantial at 64,520 pieces. This part is functionally interchangeable with the original 227079-6 and requires no design modification.

Secondary Recommendation: TE Connectivity AMP Connectors 225395-3

The 225395-3 is a parametric equivalent offering active product status and broader regulatory applicability. The primary distinction is dielectric material composition (polytetrafluoroethylene versus polyethylene), which does not affect the core RF performance specifications. This part is suitable for applications where RoHS compliance status requires clarification, as it carries "Not applicable" designation. Cable group compatibility remains identical to the main part.

Alternative Recommendation: Amphenol RF 031-326

The 031-326 provides an active alternative from a different manufacturer with extended operating temperature range (-65°C to 165°C versus -55°C to 85°C). This part supports both crimp and solder termination options, offering greater assembly flexibility. RoHS3 compliance and REACH affected status are documented. Cable group compatibility includes RG-55, 142, 223, and 400. This option is suitable for applications requiring extended thermal performance.

Consideration: Winchester Interconnect 310A205P

The 310A205P is an active alternative with weatherproof ingress protection and extended operating temperature range (-40°C to 165°C). This part is limited to RG-223 cable group compatibility and features nickel center contact plating rather than gold. Selection of this part is appropriate only when weatherproof characteristics are required and cable group limitation is acceptable.

Not Recommended for New Designs: Amphenol RF 112562

The 112562 carries "Not For New Designs" product status and is incompatible with the primary cable groups specified for the 227079-6 (RG-55, 55A, 55B, 223). This part is designed for larger diameter cables (RG-8, 8A, 9 series) and represents a different connector class. Selection of this part requires design modification and is not appropriate as a direct substitute.

Frequently Asked Questions (FAQ)

Q: Can the 5227079-6 be used as a direct replacement for the 227079-6 in existing assemblies?

A: Yes. The 5227079-6 is electrically and mechanically identical to the 227079-6 across all specified parameters. Both parts feature 50 ohm impedance, crimp termination, 4 GHz maximum frequency, 500 V voltage rating, and identical operating temperature range. No design modification is required.

Q: What is the difference between the 227079-6 and 225395-3?

A: The primary difference is dielectric material. The 227079-6 uses polyethylene (PE) dielectric, while the 225395-3 uses polytetrafluoroethylene (PTFE) dielectric. Both parts maintain identical electrical performance at 50 ohms impedance and 4 GHz maximum frequency. The 225395-3 offers active product status, whereas the 227079-6 is obsolete.

Q: Are there cable group compatibility restrictions when substituting parts?

A: Cable group compatibility must be verified during substitution. The 227079-6, 225395-3, 5225395-3, and 031-326 all support RG-223 cable. The 031-326 additionally supports RG-142 and RG-400. The 310A205P is limited to RG-223. The 112562 is designed for larger diameter cables (RG-8, 8A, 9 series) and is not compatible with the original cable group specification.

Q: What is the significance of RoHS compliance status in part selection?

A: RoHS compliance status indicates regulatory conformance for lead-free manufacturing and restricted substance limitations. The 5227079-6, 5225395-3, 031-326, and 310A205P all carry RoHS compliance certifications. The original 227079-6 is RoHS non-compliant. For applications subject to RoHS regulations, selection of a compliant alternative is mandatory.

Q: Can the 031-326 be used in applications requiring the original operating temperature range?

A: The 031-326 exceeds the original operating temperature specification, supporting -65°C to 165°C versus the 227079-6 specification of -55°C to 85°C. This part is suitable for applications within the original temperature range and additionally supports extended thermal environments. No performance degradation occurs within the original specification limits.

Q: Why is the 112562 not recommended as a substitute?

A: The 112562 is designed for larger diameter coaxial cables (RG-8, 8A, 9 series) and is incompatible with the cable groups specified for the 227079-6 (RG-55, 55A, 55B, 223). Additionally, the 112562 carries "Not For New Designs" product status. Mechanical and electrical incompatibility with the original cable specification makes this part unsuitable as a direct substitute.

Q: What packaging options are available for substitute parts?

A: The 225395-3 and 5225395-3 are supplied without specified packaging designation. The 031-326 is supplied in bulk packaging. The 310A205P packaging is not specified. The 112562 is supplied in bag packaging. Packaging selection should be coordinated with procurement requirements and assembly processes.

Q: Is the 310A205P weatherproof characteristic beneficial for all applications?

A: Weatherproof ingress protection is beneficial only for applications exposed to moisture or environmental contamination. For indoor or controlled environment applications, weatherproof characteristics provide no functional advantage. The 310A205P is appropriate only when weatherproof performance is a design requirement.
