Parameter Comparison

Engineering Selection Recommendations

917B524 (Winchester Interconnect):

• Primary selection for applications requiring maximum frequency performance at 12.5 GHz
• RoHS Compliant certification
• Established inventory availability (832 units)
• Brass center contact with gold plating provides standard RF performance characteristics
• Specified mating cycle rating of 500 cycles

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

• Suitable substitute where frequency requirement is 12.4 GHz or lower
• ROHS3 Compliant certification (enhanced compliance standard)
• Higher inventory availability (2022 units)
• Phosphor bronze center contact material offers alternative mechanical properties
• Tray packaging format
• REACH Unaffected status provides additional regulatory clarity

Both parts maintain identical impedance, mounting configuration, termination method, and dielectric material specifications. Selection between these parts should be based on frequency requirement, packaging format preference, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can PCB.SMAFST.2H.A.HT replace 917B524 in all applications?

A: PCB.SMAFST.2H.A.HT is functionally equivalent for applications operating at frequencies up to 12.4 GHz. Applications requiring the full 12.5 GHz specification of the 917B524 should use the original part number. Both parts share identical impedance, mounting type, termination method, and dielectric material.

Q: What is the difference between Solder Cup and Solder termination?

A: Both termination types use solder for electrical and mechanical connection. Solder Cup typically refers to a cup-shaped terminal designed for solder attachment, while Solder indicates solder-based termination. Both are compatible for panel mount SMA jack applications with identical electrical performance.

Q: Are the center contact materials interchangeable?

A: Brass (917B524) and Phosphor Bronze (PCB.SMAFST.2H.A.HT) are both acceptable center contact materials for 50 ohm RF connectors. Both materials, when gold-plated, provide equivalent electrical performance and contact reliability for SMA jack applications.

Q: What does ROHS3 Compliant mean compared to RoHS Compliant?

A: ROHS3 represents the third iteration of the Restriction of Hazardous Substances directive, incorporating updated substance restrictions. ROHS3 Compliant indicates enhanced regulatory compliance. Both certifications confirm the absence of restricted hazardous substances; ROHS3 represents a more current standard.

Q: Does packaging format affect electrical performance?

A: No. The 917B524 packaging format is not specified in the provided data. PCB.SMAFST.2H.A.HT is supplied in Tray packaging. Packaging format affects logistics, storage, and handling but does not alter electrical or mechanical connector performance.

Q: Are both parts suitable for the full operating temperature range?

A: The 917B524 specifies -65°C ~ 165°C operating temperature. PCB.SMAFST.2H.A.HT operating temperature is not provided in the available data. For applications requiring the full -65°C ~ 165°C range, confirm PCB.SMAFST.2H.A.HT temperature specifications with the manufacturer or use 917B524.

Q: What is the significance of MSL 1 (Unlimited)?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has minimal moisture sensitivity and does not require special moisture control during storage or handling. Both parts carry this rating, confirming equivalent moisture performance.
