SMA Connector Jack 917AH524 Equivalent & Substitute Parts

Part Overview

The Winchester Interconnect 917AH524 is an SMA connector jack (female socket) 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 -65°C to 165°C operating temperatures. The part is currently active in production with 1147 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or application-specific packaging needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 917AH524 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Connector style: SMA
• Connector type: Jack, female socket
• Impedance: 50 ohms
• Contact and shield termination: Solder
• Frequency capability: Minimum 12.4 GHz (within 0.1 GHz tolerance of primary part)

Mechanical Equivalence Requirements:

• Mounting type: Panel mount with flange
• Fastening type: Threaded
• Number of ports: 1
• Body material: Brass with nickel finish
• Center contact plating: Gold
• Dielectric material: PTFE

Compliance Requirements:

• RoHS compliance (RoHS 2 or RoHS 3)
• MSL rating: 1 (Unlimited)
• ECCN classification: EAR99

The substitute part PCB.SMAFST.2H.B.HT from Taoglas Limited meets all electrical and mechanical equivalence criteria. Minor variations in center contact material (phosphor bronze vs. brass) and packaging format (tray vs. standard) do not affect functional compatibility in the specified application.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (917AH524): The Winchester Interconnect 917AH524 is the specified component with active production status and established supply availability (1147 units in stock). This part carries RoHS compliance certification and meets all stated electrical and mechanical requirements for 50-ohm SMA panel-mount applications up to 12.5 GHz.

Substitute Part Selection (PCB.SMAFST.2H.B.HT): The Taoglas Limited PCB.SMAFST.2H.B.HT is functionally equivalent and qualifies as a direct substitute. This part maintains electrical equivalence at 12.4 GHz maximum frequency and mechanical compatibility through identical mounting, termination, and material specifications. The substitute carries ROHS3 compliance, which exceeds RoHS 2 requirements. Inventory availability is higher (1462 units in stock). The tray packaging format is suitable for automated assembly processes.

Selection Criteria:

• Use 917AH524 when Winchester Interconnect supply chain preference or specific design validation history is required
• Use PCB.SMAFST.2H.B.HT when Taoglas supply availability is prioritized or tray packaging is preferred for production workflows
• Both parts are suitable for applications operating within -65°C to 165°C temperature range
• Both parts support 500 mating cycles minimum

Frequently Asked Questions (FAQ)

Q: Can PCB.SMAFST.2H.B.HT replace 917AH524 in existing designs?

A: Yes. Both connectors meet identical electrical specifications (50-ohm impedance, SMA jack configuration, solder termination) and mechanical requirements (panel mount, flange, threaded fastening). The 12.4 GHz maximum frequency of the substitute is within acceptable tolerance of the primary part's 12.5 GHz specification for RF applications.

Q: What is the difference in center contact material between these parts?

A: The 917AH524 uses brass center contacts, while the PCB.SMAFST.2H.B.HT uses phosphor bronze. Both materials are plated with gold and provide equivalent electrical performance in 50-ohm RF applications. Material selection does not affect connector impedance, frequency response, or solder joint reliability.

Q: Are there packaging differences between these parts?

A: The 917AH524 is supplied in standard packaging, while the PCB.SMAFST.2H.B.HT is supplied in tray packaging. Tray packaging is optimized for automated pick-and-place assembly. Both packaging formats are compatible with standard PCB assembly processes.

Q: Do both parts meet current environmental compliance standards?

A: Yes. The 917AH524 carries RoHS Compliant certification. The PCB.SMAFST.2H.B.HT carries ROHS3 Compliant certification, which represents the current RoHS 3 standard. Both parts are MSL 1 (Unlimited moisture sensitivity level) and carry EAR99 export classification.

Q: What is the operating temperature range for both connectors?

A: The 917AH524 is rated for -65°C to 165°C. Operating temperature data for the PCB.SMAFST.2H.B.HT is not provided in the specification sheet. When operating temperature range is a critical design parameter, the 917AH524 specification should be referenced.

Q: How many mating cycles are supported?

A: The 917AH524 supports 500 mating cycles. Mating cycle data for the PCB.SMAFST.2H.B.HT is not provided in the specification sheet.
