Key Parameters

Substitute Part Grouping Explanation

Substitution of coaxial RF connectors is determined by strict equivalence across electrical and mechanical parameters. The 917AF524 and identified substitute parts share the following critical substitution criteria:

Electrical Parameters: Impedance matching at 50 ohms is mandatory for RF signal integrity. Both the main part and substitute maintain this specification. Maximum frequency ratings must support the intended application bandwidth; the main part operates to 12.5 GHz while the substitute operates to 12.4 GHz, representing functional equivalence within standard RF connector performance bands.

Mechanical Parameters: Connector style (SMA), connector type (Jack, Female Socket), mounting configuration (Panel Mount with Flange), and fastening method (Threaded) must be identical. Contact and shield termination methods (Solder) must match to ensure compatibility with PCB assembly processes.

Material and Environmental Specifications: Center contact plating (Gold), body finish (Nickel), and dielectric material (PTFE) are consistent across parts. Operating temperature ranges and MSL ratings ensure reliability in specified environmental conditions.

Compliance and Certification: Both parts maintain RoHS compliance status and carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for procurement and export purposes.

Engineering Selection Recommendations

Both the 917AF524 and PCB.SMAFST.2H.B.HT are active products with confirmed inventory availability and equivalent electrical performance for 50-ohm RF applications up to 12.4-12.5 GHz. Selection between these parts is based on the following engineering considerations:

Compliance Status: The 917AF524 carries RoHS Compliant certification. The PCB.SMAFST.2H.B.HT carries ROHS3 Compliant certification and includes REACH Unaffected status, providing additional regulatory documentation for applications requiring enhanced compliance verification.

Product Availability: The 917AF524 has 833 pieces in stock. The PCB.SMAFST.2H.B.HT has 1462 pieces in stock, offering greater supply availability for high-volume production requirements.

Packaging: The 917AF524 packaging specification is not provided. The PCB.SMAFST.2H.B.HT is supplied in Tray packaging, which may influence handling and assembly processes.

Material Composition: The 917AF524 features a brass center contact. The PCB.SMAFST.2H.B.HT features a phosphor bronze center contact. Both materials provide equivalent electrical performance in 50-ohm RF applications with gold plating.

Environmental Specifications: The 917AF524 specifies operating temperature range of -65°C to 165°C. The PCB.SMAFST.2H.B.HT does not provide operating temperature specification in available documentation. For applications requiring confirmed temperature performance across the full -65°C to 165°C range, the 917AF524 is the specified selection.

Frequently Asked Questions (FAQ)

Q: Can the PCB.SMAFST.2H.B.HT substitute for the 917AF524 in all applications?

A: The PCB.SMAFST.2H.B.HT is electrically and mechanically equivalent for RF applications up to 12.4 GHz. The maximum frequency difference of 0.1 GHz is within standard RF connector performance tolerance. However, if your application requires confirmed operation across the full -65°C to 165°C temperature range, verify that the PCB.SMAFST.2H.B.HT meets your specific environmental requirements, as operating temperature specification is not provided for this part.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) Impedance matching at 50 ohms, (2) Maximum frequency rating sufficient for application bandwidth, (3) Connector style and type (SMA Jack, Female Socket), (4) Contact and shield termination method (Solder), and (5) Number of ports (1). Both parts meet these criteria.

Q: Are there differences in center contact material between these parts?

A: Yes. The 917AF524 uses brass center contact material, while the PCB.SMAFST.2H.B.HT uses phosphor bronze. Both materials are gold-plated and provide equivalent electrical performance in 50-ohm RF applications. Material selection does not affect RF signal integrity or impedance matching.

Q: What is the significance of the packaging difference?

A: The 917AF524 packaging specification is not provided in available documentation. The PCB.SMAFST.2H.B.HT is supplied in Tray packaging. Packaging affects component handling, storage, and assembly line integration. Confirm packaging compatibility with your assembly process requirements.

Q: Do both parts meet RoHS requirements?

A: Yes. The 917AF524 is RoHS Compliant. The PCB.SMAFST.2H.B.HT is ROHS3 Compliant and REACH Unaffected. Both parts satisfy RoHS regulatory requirements. The PCB.SMAFST.2H.B.HT provides additional REACH documentation for applications requiring enhanced regulatory verification.

Q: What is the mating cycle rating difference?

A: The 917AF524 specifies 500 mating cycles. The PCB.SMAFST.2H.B.HT does not provide mating cycle specification in available documentation. For applications requiring confirmed mechanical durability across multiple connection cycles, the 917AF524 provides documented performance data.

Q: Are both parts suitable for solder termination assembly?

A: Yes. Both the 917AF524 and PCB.SMAFST.2H.B.HT feature solder termination for center contact and shield. Both are compatible with standard PCB solder assembly processes and reflow soldering procedures.

Q: What inventory considerations should influence part selection?

A: The 917AF524 has 833 pieces in stock. The PCB.SMAFST.2H.B.HT has 1462 pieces in stock. For applications requiring immediate delivery or high-volume production, the PCB.SMAFST.2H.B.HT offers greater inventory availability.
