Key Parameters

Substitute Part Grouping Explanation

Substitution of coaxial RF connectors is determined by strict equivalence across electrical and mechanical parameters. The primary criteria for substitution of the 448103-2 are:

Electrical Parameters:

• Connector style must be SMA
• Connector type must be Jack, Female Socket
• Impedance must be 50 Ohms
• Maximum frequency rating must be 12.4 GHz or greater
• Mating cycles must be 500 or greater

Mechanical Parameters:

• Contact termination must be Crimp
• Shield termination must be Crimp
• Mounting type must be Panel Mount
• Mounting feature must be Bulkhead - Front Side Nut
• Cable group compatibility must include RG-174, RG-188, and RG-316
• Fastening type must be Threaded
• Number of ports must be 1

The substitute part 5448103-2 meets all electrical and mechanical equivalence criteria. However, product status differences and compliance certifications differ between the main part and substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (448103-2): The 448103-2 is the recommended selection for new designs and applications. This part maintains Active product status, ensuring long-term availability and manufacturer support. The part is currently in stock with 1147 pieces available. For applications where RoHS compliance is not a design requirement, this part is suitable for immediate deployment.

Substitute Selection (5448103-2): The 5448103-2 is electrically and mechanically equivalent to the 448103-2 across all critical RF and mechanical parameters. This substitute part is designated as Obsolete, indicating that it is no longer in active production. The 5448103-2 carries RoHS Compliant certification and REACH Affected status, making it suitable for applications with environmental compliance requirements. Selection of the 5448103-2 should be limited to applications where RoHS compliance is mandatory and where the Obsolete status does not conflict with supply chain or lifecycle requirements. Current inventory of 1092 pieces is available.

Compliance Considerations: Applications requiring RoHS compliance should specify the 5448103-2. Applications without RoHS requirements should specify the 448103-2 to ensure continued product availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the 5448103-2 be used as a direct replacement for the 448103-2?

A: The 5448103-2 is electrically and mechanically equivalent to the 448103-2. Both parts share identical SMA connector style, 50 Ohm impedance, crimp termination, panel mount configuration, and 12.4 GHz maximum frequency rating. Direct substitution is possible from a functional standpoint. However, the 5448103-2 is designated as Obsolete, while the 448103-2 is Active. For new designs, the 448103-2 is the preferred selection.

Q: What are the key electrical parameters that must match for substitution?

A: The critical electrical parameters for SMA coaxial connector substitution are connector style (SMA), connector type (Jack, Female Socket), impedance (50 Ohms), and maximum frequency rating (12.4 GHz). Both the 448103-2 and 5448103-2 meet these requirements.

Q: What are the key mechanical parameters that must match for substitution?

A: The critical mechanical parameters are contact termination (Crimp), shield termination (Crimp), mounting type (Panel Mount), mounting feature (Bulkhead - Front Side Nut), cable group compatibility (RG-174, RG-188, RG-316), fastening type (Threaded), and number of ports (1). Both parts are mechanically equivalent across these parameters.

Q: What is the difference in RoHS compliance between these parts?

A: The 448103-2 has RoHS Status listed as Not applicable, while the 5448103-2 is RoHS Compliant. Applications requiring RoHS certification should specify the 5448103-2.

Q: What does Obsolete product status mean for the 5448103-2?

A: Obsolete status indicates that the 5448103-2 is no longer in active production by the manufacturer. While current inventory is available (1092 pieces), future availability cannot be guaranteed. The 448103-2, with Active status, is the recommended selection for applications requiring long-term supply assurance.

Q: Are there differences in insertion loss between these parts?

A: The 448103-2 specifies insertion loss of 0.3 dB. The 5448103-2 does not provide insertion loss specification in the available data. For applications where insertion loss is a critical parameter, the 448103-2 is the specified selection.

Q: What cable types are compatible with both parts?

A: Both the 448103-2 and 5448103-2 are compatible with RG-174, RG-188, and RG-316 cable groups. Cable selection should be based on application impedance and frequency requirements.

Q: What is the mating cycle rating for these connectors?

A: Both the 448103-2 and 5448103-2 are rated for 500 mating cycles, indicating the number of times the connector can be mated and unmated while maintaining electrical and mechanical specifications.
