Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 917B524FT is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: SMA
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Solder
• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Fastening Type: Threaded
• Number of Ports: 1
• Dielectric Material: PTFE

Allowable Variation Parameters:

• Frequency - Max: Substitute must meet or exceed 12.4 GHz minimum
• Operating Temperature: Substitute must support the required operating range or be verified for specific application requirements
• Mating Cycles: Substitute specifications may differ based on application duty cycle
• Body Material and Finish: Variations permitted provided core RF performance is maintained
• Center Contact Material and Plating: Variations permitted provided electrical performance is maintained

The substitute part PCB.SMAFST.2H.A.HT manufactured by Taoglas Limited satisfies all mandatory matching parameters and meets the allowable variation criteria for frequency performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 917B524FT and PCB.SMAFST.2H.A.HT are classified as Active products with full regulatory compliance. The 917B524FT maintains RoHS compliance, while the substitute part PCB.SMAFST.2H.A.HT carries ROHS3 compliance and REACH Unaffected status, indicating enhanced environmental regulatory alignment.

The frequency specification difference of 0.1 GHz (12.5 GHz versus 12.4 GHz) falls within acceptable tolerance for most RF applications operating below the maximum rated frequency of either component. Both connectors maintain identical impedance, dielectric material, and termination specifications critical to RF performance.

The center contact material variation from Brass to Phosphor Bronze in the substitute part does not compromise electrical performance, as both materials are standard in RF connector applications and both components feature gold plating on the contact surface.

Selection between these parts should be based on availability, packaging requirements (Winchester Interconnect packaging not specified; Taoglas supplied in Tray), and supplier lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can PCB.SMAFST.2H.A.HT replace 917B524FT in all applications?

A: Yes, provided the application operates at frequencies not exceeding 12.4 GHz. Both connectors meet the 50-ohm impedance requirement, feature identical mounting configurations, and maintain PTFE dielectric material specifications. The 0.1 GHz frequency difference is not significant for applications operating below this threshold.

Q: What is the significance of the center contact material difference?

A: The 917B524FT uses Brass while PCB.SMAFST.2H.A.HT uses Phosphor Bronze. Both materials are standard in RF connector manufacturing. Both components feature gold plating on the contact surface, which provides the primary electrical interface. The material difference does not affect RF performance or electrical characteristics.

Q: Are there packaging differences between these parts?

A: Yes. The 917B524FT packaging specification is not provided in the available data. The PCB.SMAFST.2H.A.HT is supplied in Tray packaging. Verify packaging compatibility with your assembly and handling requirements before selection.

Q: Do both parts meet current environmental regulations?

A: Yes. The 917B524FT is RoHS Compliant. The PCB.SMAFST.2H.A.HT is ROHS3 Compliant and REACH Unaffected, indicating compliance with the most current environmental standards.

Q: What is the mating cycle difference between these connectors?

A: The 917B524FT specifies 500 mating cycles. The PCB.SMAFST.2H.A.HT mating cycle specification is not provided. For applications requiring high-cycle mating operations, verify the actual mating cycle rating of the substitute part with the manufacturer.

Q: Are the operating temperature ranges compatible?

A: The 917B524FT operates from -65°C to 165°C. The PCB.SMAFST.2H.A.HT operating temperature specification is not provided in the available data. For applications requiring operation outside standard temperature ranges, verify the actual operating temperature specification of the substitute part.
