Substitute Part Grouping Explanation

Substitute parts for the 2-225395-0 are categorized into two distinct groups based on electrical and mechanical compatibility parameters:

Group 1: Parametric Equivalent (50 Ohm, 4 GHz)

The parametric equivalent maintains the critical electrical specifications of the original part: 50 Ohm impedance, 4 GHz maximum frequency, and identical mechanical form factor (BNC plug, male pin, free hanging crimp configuration). This group includes parts that provide direct functional replacement without impedance or frequency derating.

Group 2: Impedance-Rated Substitutes (75 Ohm, 1 GHz)

These Winchester Interconnect BNC plug connectors operate at 75 Ohm impedance with a maximum frequency of 1 GHz. While maintaining identical connector style, type, termination method, and mounting configuration, these parts operate at reduced frequency bandwidth and different impedance specification. Substitution in this group is applicable only when system design permits 75 Ohm impedance operation and frequency requirements do not exceed 1 GHz.

Key Parameters Determining Substitution Eligibility:

Connector Style: BNC (fixed)
Connector Type: Plug, Male Pin (fixed)
Contact Termination: Crimp (fixed)

Engineering Selection Recommendations

Primary Selection: TE Connectivity Aerospace, Defense and Marine 9-331350-5

The 9-331350-5 is the recommended parametric equivalent for direct replacement of the obsolete 2-225395-0. This part maintains identical electrical specifications (50 Ohm impedance, 4 GHz maximum frequency) and mechanical configuration (BNC plug, male pin, free hanging crimp). Both parts are manufactured by TE Connectivity, ensuring design continuity and compatibility with existing cable assemblies specified for Belden 8212 cable. The 9-331350-5 carries active product status, ensuring long-term availability and supply chain stability. While RoHS compliance status differs between the original and substitute, the 9-331350-5 provides the most direct functional replacement without electrical or frequency derating.

Secondary Selection: Winchester Interconnect BNC Plug Connectors (SBC Series)

The Winchester Interconnect SBC1426A, SBC8241F, SBC9165, SBC9171, SBC9259, SBC9265, and SBC9659 connectors are applicable as substitutes only when system design specifications permit 75 Ohm impedance operation and maximum frequency requirements do not exceed 1 GHz. All Winchester Interconnect parts carry active product status and RoHS compliance certification, providing regulatory advantage over the obsolete original part. These connectors maintain identical mechanical form factor and termination method, enabling physical compatibility with existing crimp tooling and assembly processes. Selection among the Winchester Interconnect options is determined by cable group compatibility: SBC1426A for Belden 1426A, SBC8241F for Belden 8241F, SBC9165 for Belden 9165, SBC9171 for Belden 9171, SBC9259 for RG-59 and Belden 9259, SBC9265 for Belden 9265, and SBC9659 for Belden 9659.

Frequently Asked Questions (FAQ)

Q: Can the 9-331350-5 be used as a direct replacement for the 2-225395-0?

A: Yes. The 9-331350-5 maintains identical impedance (50 Ohms), maximum frequency (4 GHz), connector style (BNC plug, male pin), termination method (crimp), and mounting configuration (free hanging in-line). Both parts are compatible with Belden 8212 cable and operate at 500 V with 0.2 dB insertion loss.

Q: What is the primary difference between Group 1 and Group 2 substitutes?

A: Group 1 (9-331350-5) maintains the original 50 Ohm impedance and 4 GHz frequency specification. Group 2 (Winchester Interconnect SBC series) operates at 75 Ohm impedance with 1 GHz maximum frequency. Group 2 substitution is applicable only when system design permits these electrical parameter changes.

Q: Are all Winchester Interconnect SBC series connectors interchangeable?

A: All Winchester Interconnect SBC series connectors share identical electrical and mechanical specifications (75 Ohm impedance, 1 GHz frequency, BNC plug configuration, crimp termination). The primary difference is cable group compatibility. Selection should be based on the specific cable type used in the application.

Q: What is the significance of the cable group designation?

A: Cable group designation indicates the specific coaxial cable type for which each connector is optimized. SBC1426A is designed for Belden 1426A cable, SBC8241F for Belden 8241F, SBC9165 for Belden 9165, SBC9171 for Belden 9171, SBC9259 for RG-59 and Belden 9259, SBC9265 for Belden 9265, and SBC9659 for Belden 9659. Using the connector matched to the cable type ensures proper impedance matching and signal integrity.

Q: Does the 9-331350-5 include the same components as the 2-225395-0?

A: The 2-225395-0 includes 3 pieces (1 connector, 1 contact, 1 ferrule). The 9-331350-5 includes 4 pieces (1 connector, 1 contact, 1 ferrule, 1 gasket). The additional gasket in the 9-331350-5 does not affect compatibility but provides enhanced sealing capability.

Q: What is the impact of the frequency difference between 4 GHz and 1 GHz?

A: The 4 GHz specification of the original 2-225395-0 and the 9-331350-5 supports higher frequency applications including microwave and satellite communications. The 1 GHz specification of Winchester Interconnect SBC series connectors is suitable for video, RF, and lower frequency data transmission applications. Substitution with 1 GHz-rated connectors is valid only when system frequency requirements do not exceed 1 GHz.

Q: Are the Winchester Interconnect connectors RoHS compliant?

A: Yes. All Winchester Interconnect SBC series connectors (SBC1426A, SBC8241F, SBC9165, SBC9171, SBC9259, SBC9265, SBC9659) carry RoHS compliance certification. The original 2-225395-0 is RoHS non-compliant, and the 9-331350-5 carries "Not applicable" status. For applications requiring RoHS compliance, Winchester Interconnect options provide regulatory advantage.

Q: What is the mating cycle rating and its importance?

A: Both the original 2-225395-0 and all substitute parts are rated for 500 mating cycles, indicating the connector can withstand 500 connect-disconnect operations before performance degradation. This specification is consistent across all options, ensuring equivalent mechanical durability.

Q: Can the 9-331350-5 be used with cables specified for the original 2-225395-0?

A: Yes. Both the 2-225395-0 and 9-331350-5 are compatible with Belden 8212 cable. The 9-331350-5 maintains the same 50 Ohm impedance and crimp termination method, ensuring compatibility with existing cable assemblies and system designs.
