The substitute part maintains mechanical and environmental compatibility but introduces variations in electrical characteristics and termination methodology that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (Amphenol RF 182324): The Amphenol RF 182324 is the specified component for applications requiring 50 Ohm impedance with solder termination. This part maintains active product status and full ROHS3 compliance. The solder termination method provides permanent connection suitable for fixed installations. The 2.5 GHz maximum frequency rating and 50 Ohm impedance specification establish this as the baseline reference for RF performance in this connector category.

Substitute Part Selection (TE Connectivity 5228664-2): The TE Connectivity AMP Connectors 5228664-2 serves as a substitute when crimp termination is preferred over solder termination. This part maintains active product status and ROHS3 compliance. The crimp termination method enables field assembly without soldering equipment. However, the non-constant impedance specification and 2 GHz maximum frequency rating represent reduced electrical performance compared to the primary part. The cable group compatibility excludes RG-55, limiting application scope. This substitute is suitable for applications where termination methodology takes precedence over impedance specification and frequency margin.

Both parts maintain identical operating temperature ranges, voltage ratings, and mating cycle specifications, ensuring mechanical and environmental compatibility within their respective termination methodologies.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5228664-2 directly replace the Amphenol RF 182324 in all applications?

A: No. While both connectors share the same UHF Mini form factor, threaded fastening, and environmental ratings, the TE Connectivity part introduces three critical differences: non-constant impedance versus 50 Ohm specification, 2 GHz versus 2.5 GHz frequency rating, and crimp versus solder termination. Applications requiring 50 Ohm impedance or frequencies above 2 GHz must use the Amphenol RF 182324.

Q: What is the significance of the impedance difference between these parts?

A: The Amphenol RF 182324 maintains constant 50 Ohm impedance throughout its operating range, a critical specification for RF signal integrity. The TE Connectivity 5228664-2 specifies non-constant impedance, meaning impedance varies across the frequency spectrum. This difference affects signal reflection, insertion loss, and overall RF performance. Applications with strict impedance requirements must use the 50 Ohm part.

Q: How does the frequency rating difference impact part selection?

A: The Amphenol RF 182324 operates to 2.5 GHz while the TE Connectivity 5228664-2 operates to 2 GHz. Applications operating above 2 GHz require the Amphenol RF part. Applications operating at or below 2 GHz may use either part, subject to impedance and termination requirements.

Q: What are the cable compatibility implications?

A: The Amphenol RF 182324 supports RG-55, RG-142, RG-223, and RG-400 cable groups. The TE Connectivity 5228664-2 supports RG-142, RG-223, and RG-400. Applications using RG-55 cable must use the Amphenol RF part. Both parts support RG-142, RG-223, and RG-400 cables.

Q: What is the difference between solder and crimp termination?

A: Solder termination (Amphenol RF 182324) creates a permanent connection through heat-based bonding, suitable for fixed installations and requiring soldering equipment. Crimp termination (TE Connectivity 5228664-2) creates a mechanical connection through compression, enabling field assembly without soldering equipment. Termination method selection depends on installation methodology and equipment availability.

Q: Are both parts RoHS compliant?

A: Yes. Both the Amphenol RF 182324 and TE Connectivity 5228664-2 are ROHS3 compliant, meeting environmental and hazardous substance restrictions for electronic components.

Q: What packaging differences exist between these parts?

A: The Amphenol RF 182324 is supplied in Bag packaging with 761 pieces in stock. The TE Connectivity 5228664-2 is supplied in Bulk packaging with 1731 pieces in stock. Packaging format may affect procurement, handling, and inventory management procedures.

Q: Do both parts support the same mating cycle rating?

A: Yes. Both parts are rated for 500 mating cycles, indicating equivalent mechanical durability and connector life expectancy under normal use conditions.
