Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2-329445-1 is determined by strict equivalence across the following critical parameters: connector style (BNC), connector type (plug, male pin), impedance (50 ohms), mounting type (free hanging in-line), fastening type (bayonet lock), voltage rating (500 V), and mating cycles (500). All substitute parts must maintain these core electrical and mechanical characteristics to ensure functional compatibility within the original application.

The substitute parts are grouped into three categories based on their relationship to the main part:

Parametric Equivalent: Parts that match all critical parameters with minor variations in non-functional specifications such as dielectric material composition or packaging quantity.

Direct Manufacturer Alternative: Parts that provide functional equivalence with enhanced performance specifications (higher frequency rating, extended temperature range) while maintaining core compatibility parameters.

Similar Manufacturer Alternative: Parts that satisfy core electrical and mechanical requirements but may have restricted cable group compatibility or different body finish specifications.

Parameter Comparison

Engineering Selection Recommendations

2-5329083-1 (TE Connectivity AMP Connectors - Parametric Equivalent): This part maintains identical electrical and mechanical specifications to the 2-329445-1 across all critical parameters including impedance, frequency rating, voltage rating, operating temperature range, and mating cycles. The primary distinction is the dielectric material composition (polypropylene versus PTFE) and RoHS compliance status. This part is classified as obsolete, matching the status of the main part. Selection of this substitute is appropriate for direct replacement in applications where RoHS compliance is not mandated and dielectric material substitution is acceptable within system design parameters.

031-4321 (Amphenol RF - Direct Manufacturer Alternative): This connector provides enhanced performance specifications with a maximum frequency rating of 4 GHz (versus 2.5 GHz) and extended operating temperature range of -65°C to 165°C (versus -55°C to 85°C). The contact termination differs from the main part, utilizing crimp or solder termination instead of push-on termination. This part is classified as active product status with ROHS3 compliance and REACH affected designation. Selection of this substitute is appropriate for applications requiring higher frequency performance or extended temperature operation, provided that the crimp or solder termination method is compatible with the cable assembly process.

0731740093 (Molex - Similar Manufacturer Alternative): This connector maintains core electrical and mechanical compatibility with 50 ohms impedance, 500 V voltage rating, and bayonet lock fastening. The body finish differs (nickel versus silver), and cable group compatibility is restricted to RG-58 and 141 cable types. This part is classified as active product status with ROHS3 compliance and REACH unaffected designation. Selection of this substitute is appropriate for applications utilizing RG-58 or 141 cable groups where nickel body finish is acceptable and frequency specifications are not critical.

Frequently Asked Questions (FAQ)

Q: Can the 2-5329083-1 be used as a direct replacement for the 2-329445-1?

A: The 2-5329083-1 is functionally equivalent across all critical electrical and mechanical parameters including impedance, frequency rating, voltage rating, operating temperature, and mating cycles. The dielectric material differs (polypropylene versus PTFE), which does not affect core connector functionality. This part is suitable for direct replacement in applications where RoHS compliance is not required.

Q: What is the primary difference between the 031-4321 and the main part 2-329445-1?

A: The 031-4321 features enhanced performance specifications with a maximum frequency rating of 4 GHz (compared to 2.5 GHz) and extended operating temperature range of -65°C to 165°C (compared to -55°C to 85°C). The contact termination method differs: the 031-4321 uses crimp or solder termination, while the 2-329445-1 uses push-on termination. The 031-4321 is an active product with ROHS3 compliance.

Q: Is the 0731740093 compatible with all cable groups supported by the 2-329445-1?

A: No. The 0731740093 supports only RG-58 and 141 cable groups, whereas the 2-329445-1 supports RG-59, 59A, 59B, 62, 62A, 62B, 124, 140, and 210 cable groups. The 0731740093 is suitable only for applications utilizing RG-58 or 141 cables.

Q: What compliance certifications should be considered when selecting a substitute?

A: The main part 2-329445-1 is RoHS non-compliant. The 2-5329083-1 is RoHS compliant. Both the 031-4321 and 0731740093 are ROHS3 compliant. If RoHS compliance is required for the application, the 2-5329083-1, 031-4321, or 0731740093 are appropriate selections. The 031-4321 carries REACH affected status, while the 0731740093 is REACH unaffected.

Q: Can the 031-4321 be used in applications requiring push-on contact termination?

A: No. The 031-4321 utilizes crimp or solder contact termination, whereas the 2-329445-1 uses push-on termination. If the application requires push-on termination, the 2-5329083-1 is the appropriate substitute. If the application can accommodate crimp or solder termination, the 031-4321 is suitable.

Q: What is the significance of the body finish difference between the 0731740093 and the main part?

A: The 2-329445-1 features a silver body finish, while the 0731740093 features a nickel body finish. Both finishes provide corrosion resistance and electrical conductivity. The selection between silver and nickel finish depends on application-specific requirements regarding environmental exposure, contact resistance characteristics, and system design specifications.

Q: Are all substitute parts rated for the same voltage and mating cycles as the main part?

A: Yes. All substitute parts (2-5329083-1, 031-4321, and 0731740093) are rated for 500 V voltage and 500 mating cycles, matching the specifications of the main part 2-329445-1.
