Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 901-9909 are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Matching Criteria:

• Connector Style: SMA
• Connector Type: Receptacle, Female Socket
• Impedance: 50 Ohms
• Shield Termination: Solder
• Mounting Type: Panel Mount
• Fastening Type: Threaded
• Center Contact Material: Beryllium Copper
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Mating Cycles: 500

Secondary Compatibility Factors:

• Contact Termination method (Solder or Solder Cup)
• Mounting Feature configuration (Bulkhead orientation)
• Center Contact Plating: Gold
• Body Material: Stainless Steel

The TE Connectivity AMP Connectors part 1053111-1 qualifies as a substitute based on matching SMA receptacle female socket configuration, 50 ohm impedance, solder shield termination, panel mount design, threaded fastening, and identical dielectric and center contact materials. Variations in mounting feature orientation and contact termination method (solder cup versus solder) represent acceptable design alternatives within the SMA connector family.

Engineering Selection Recommendations

Amphenol RF 901-9909 (Primary Selection)

The Amphenol RF 901-9909 is the recommended primary selection. This part maintains Active product status, ensuring continued availability and manufacturer support. It carries ROHS3 compliance certification and operates across an extended temperature range of -65°C to 165°C, providing superior thermal performance for demanding applications. The part is currently in stock with 1135 units available.

TE Connectivity AMP Connectors 1053111-1 (Substitute Selection)

The TE Connectivity 1053111-1 qualifies as a functional substitute when the Amphenol RF 901-9909 is unavailable. This part maintains RoHS compliance and identical moisture sensitivity rating. However, the following factors require consideration:

• Product Status: Obsolete. Future availability cannot be guaranteed.
• Operating Temperature Range: Limited to -65°C to 125°C, reducing the upper thermal operating window by 40°C compared to the primary part.
• Mounting Feature: Front side nut configuration differs from rear side nut on the primary part, requiring mechanical design verification for panel integration.
• Contact Termination: Solder cup termination differs from direct solder termination, affecting PCB assembly compatibility.

Both parts maintain identical 50 ohm impedance, SMA connector interface, beryllium copper center contact material, PTFE dielectric, and 500 mating cycle rating. Selection between these parts depends on application temperature requirements, panel mounting geometry constraints, and PCB assembly process compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1053111-1 directly replace the Amphenol RF 901-9909 in all applications?

A: Direct replacement is not universal. Both parts share identical SMA receptacle female socket configuration, 50 ohm impedance, and core electrical characteristics. However, the TE Connectivity part operates only to 125°C maximum, compared to 165°C for the Amphenol part. Applications requiring operation above 125°C require the Amphenol RF 901-9909. Additionally, the mounting feature orientation differs (front side nut versus rear side nut), requiring mechanical design verification for panel integration compatibility.

Q: What is the difference between solder and solder cup termination?

A: Solder termination involves direct solder connection of the center contact and shield to PCB pads or cable conductors. Solder cup termination features a cup-shaped contact receptacle designed to accept wire insertion followed by solder filling. The Amphenol RF 901-9909 uses direct solder termination, while the TE Connectivity 1053111-1 uses solder cup termination. PCB assembly processes and cable attachment methods must accommodate the specific termination style selected.

Q: Are both parts RoHS compliant?

A: Yes. The Amphenol RF 901-9909 carries ROHS3 compliance certification. The TE Connectivity 1053111-1 carries RoHS compliance certification. Both parts meet regulatory requirements for hazardous substance restrictions. ROHS3 represents a more recent compliance standard than RoHS.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. Parts with MSL 1 have unlimited shelf life and do not require special moisture control handling during storage or assembly. Both the Amphenol RF 901-9909 and TE Connectivity 1053111-1 carry this classification.

Q: How do the mating cycle ratings affect component selection?

A: Both parts are rated for 500 mating cycles, indicating the number of times the connector can be mated and unmated before performance degradation. This rating is identical between the primary and substitute parts, ensuring equivalent mechanical durability for connector interface cycling applications.

Q: What is the significance of the bulkhead mounting feature difference?

A: The Amphenol RF 901-9909 features bulkhead rear side nut mounting, while the TE Connectivity 1053111-1 features bulkhead front side nut mounting. This difference affects the physical orientation and installation method on the panel. Rear side nut mounting secures the connector from behind the panel, while front side nut mounting secures from the front. Panel geometry and assembly access requirements determine which configuration is suitable for a specific application.

Q: Can these connectors be used interchangeably in RF applications?

A: Both connectors maintain 50 ohm impedance and SMA interface specifications required for RF applications. Electrical performance characteristics are equivalent for impedance matching and signal integrity. However, operating temperature range differences and mounting feature variations require application-specific evaluation before interchangeable use.
