917AS524 SMA Connector Jack Equivalent & Substitute Parts

Part Overview

The 917AS524 is an SMA connector jack (female socket) manufactured by Winchester Interconnect, designed for 50-ohm RF applications. This panel-mount solder-terminated connector operates across a frequency range up to 12.5 GHz and is rated for operating temperatures between -65°C and 165°C. The part is currently active in production with 839 pieces available in inventory. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component selection from multiple qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 917AS524 are qualified based on strict electrical and mechanical parameter alignment. The following parameters must match or remain compatible for substitution:

Critical 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
• Body Material: Brass
• Body Finish: Nickel
• Center Contact Plating: Gold
• Dielectric Material: PTFE
• RoHS Compliance Status: Active

Allowable Parameter Variations:

• Frequency - Max: Substitute must support minimum 12.4 GHz (917AS524 operates at 12.5 GHz)
• Center Contact Material: Phosphor Bronze is acceptable as an alternative to Brass
• Operating Temperature: Substitute may have unspecified operating temperature range if primary specifications are met
• Mating Cycles: Substitute may have unspecified mating cycle rating if primary specifications are met
• Packaging: Tray packaging is acceptable as an alternative to unspecified packaging

Parameter Comparison

Engineering Selection Recommendations

Both the 917AS524 and PCB.SMAFST.2H.B.HT are active production parts with equivalent electrical and mechanical specifications for SMA jack connector applications. Selection between these parts is based on the following engineering criteria:

917AS524 (Winchester Interconnect):

• RoHS Compliant certification
• Frequency rating of 12.5 GHz
• Operating temperature range specified: -65°C to 165°C
• Mating cycle rating: 500 cycles
• Current inventory: 839 pieces

PCB.SMAFST.2H.B.HT (Taoglas Limited):

• ROHS3 Compliant certification (higher environmental standard)
• Frequency rating of 12.4 GHz
• Voltage rating specified: 335 V
• REACH Unaffected status documented
• Current inventory: 1462 pieces
• Packaging: Tray

Both parts meet the core 50-ohm SMA jack solder-terminated panel-mount requirements. The 917AS524 provides a marginally higher frequency specification (12.5 GHz versus 12.4 GHz). The PCB.SMAFST.2H.B.HT offers ROHS3 compliance and higher inventory availability. Center contact material differs (Brass versus Phosphor Bronze), both acceptable for this application class. Selection should be based on specific application frequency requirements, compliance certifications needed, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the PCB.SMAFST.2H.B.HT substitute for the 917AS524 in all applications?

A: The PCB.SMAFST.2H.B.HT is electrically and mechanically compatible with the 917AS524 for standard SMA jack 50-ohm solder-terminated panel-mount applications. The frequency specification difference (12.4 GHz versus 12.5 GHz) is negligible for most RF applications. Applications requiring operation specifically at or above 12.5 GHz should use the 917AS524.

Q: What is the difference between the center contact materials?

A: The 917AS524 uses Brass center contacts, while the PCB.SMAFST.2H.B.HT uses Phosphor Bronze. Both materials are standard for SMA connectors in this impedance class and provide equivalent electrical performance when gold-plated.

Q: Are there packaging differences between these parts?

A: The 917AS524 packaging is unspecified in the provided data. The PCB.SMAFST.2H.B.HT is supplied in Tray packaging. Packaging differences do not affect electrical or mechanical compatibility.

Q: What is the significance of ROHS3 compliance versus RoHS compliance?

A: Both parts meet RoHS environmental standards. The PCB.SMAFST.2H.B.HT carries ROHS3 certification, which represents the current RoHS Directive 2011/65/EU standard. The 917AS524 is RoHS Compliant. Both are acceptable for applications requiring RoHS compliance.

Q: Do these connectors have different operating temperature ranges?

A: The 917AS524 specifies an operating temperature range of -65°C to 165°C. The PCB.SMAFST.2H.B.HT operating temperature range is not provided in the available data. For applications requiring operation outside standard temperature ranges, the 917AS524 with specified temperature ratings should be selected.

Q: What is the mating cycle rating for the PCB.SMAFST.2H.B.HT?

A: The mating cycle rating for the PCB.SMAFST.2H.B.HT is not provided in the available data. The 917AS524 is rated for 500 mating cycles. For applications with high connector mating frequency requirements, the 917AS524 with specified mating cycle rating should be selected.

Q: Are both parts suitable for solder termination?

A: Yes. Both the 917AS524 and PCB.SMAFST.2H.B.HT feature solder termination for both contact and shield, making them suitable for direct PCB soldering applications.
