Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 2081203-9 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: SMA
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Solder
• Mounting Type: Free Hanging (In-Line), Right Angle
• Cable Group: RG-405 (.085" Semi Rigid)
• Fastening Type: Threaded
• Number of Ports: 1

Allowable Variation Parameters:

• Frequency - Max: Substitute must meet or exceed 18 GHz requirement
• Operating Temperature: Substitute must cover or exceed -65°C ~ 85°C range
• Voltage Rating: Substitute must meet or exceed 335 V rating
• Mating Cycles: Substitute must meet or exceed 500 cycles
• Shield Termination: May differ from crimp to solder
• Center Contact Material: May vary (Copper Alloy or Brass acceptable)
• Body Material: May vary (Zinc or Brass acceptable)
• Body Finish: May vary (Nickel or Gold acceptable)
• Center Contact Plating: Gold plating acceptable
• Dielectric Material: May vary (PMP or PTFE acceptable)
• Product Status: Active status preferred for obsolete parts

The substitute part TE Connectivity 3-1478906-0 meets all mandatory matching parameters and operates within allowable variation ranges, establishing functional equivalence for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 3-1478906-0 serves as a functional equivalent for the obsolete 2081203-9 based on the following engineering criteria:

Mechanical and Electrical Compatibility: All mandatory parameters align between the main part and substitute, including connector style, type, impedance, termination method, mounting configuration, and cable compatibility. Both components feature threaded fastening and single-port architecture suitable for identical mechanical integration.

Product Status Advantage: The substitute part maintains active product status with current manufacturing support, eliminating supply chain discontinuity associated with the obsolete main part. This status ensures availability for production quantities and field service requirements.

Compliance Enhancement: The substitute part carries RoHS Compliant certification, providing regulatory advantage for applications subject to environmental compliance mandates. The main part does not specify RoHS status.

Frequency Limitation: The substitute part specifies a maximum frequency of 6 GHz, compared to the main part's 18 GHz rating. Applications requiring operation above 6 GHz require verification that the substitute meets specific frequency performance requirements.

Material and Finish Variations: The substitute employs brass body construction with gold finish and PTFE dielectric material, compared to the main part's zinc body with nickel finish and PMP dielectric. These material variations remain within acceptable ranges for 50-ohm SMA connector applications and do not preclude functional substitution.

Shield Termination Difference: The substitute features solder shield termination, whereas the main part specifies crimp termination. Both termination methods are standard for SMA connectors and do not prevent direct replacement in solder-based assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-1478906-0 directly replace the 2081203-9 in existing designs?

A: The substitute part matches all mandatory mechanical and electrical parameters required for SMA connector plug applications. Direct replacement is supported for applications operating at frequencies up to 6 GHz. Applications requiring operation above 6 GHz require frequency performance verification against specific design requirements.

Q: What is the significance of the frequency difference between the main part and substitute?

A: The main part is rated to 18 GHz maximum frequency, while the substitute is rated to 6 GHz. This difference reflects the frequency bandwidth each connector supports. For applications operating within the 6 GHz limit, the substitute provides equivalent performance. Applications requiring higher frequency operation must confirm that 6 GHz operation meets system specifications.

Q: Are there differences in assembly compatibility between the main part and substitute?

A: Both parts feature solder contact termination and threaded fastening suitable for identical assembly processes. The substitute's solder shield termination (versus the main part's crimp termination) is compatible with standard solder-based assembly workflows. No assembly process modifications are required for substitution.

Q: What is the impact of material composition differences?

A: The substitute employs brass body construction with PTFE dielectric material, compared to the main part's zinc body with PMP dielectric. Both material combinations are standard for 50-ohm SMA connectors and maintain equivalent electrical performance and environmental stability across the specified operating temperature range.

Q: Does the substitute part include any additional components?

A: The substitute part includes two components: one connector and one end cap. The main part does not specify included components. The end cap provides protective coverage for the connector when not in use.

Q: What is the RoHS compliance advantage of the substitute part?

A: The substitute part carries RoHS Compliant certification, confirming compliance with Restriction of Hazardous Substances regulations. This certification is required for applications subject to environmental compliance mandates in regulated markets. The main part does not specify RoHS status.

Q: Are the mating cycle ratings equivalent between the main part and substitute?

A: Both parts specify 500 mating cycles, indicating equivalent mechanical durability and connector lifespan under repeated connection and disconnection operations.

Q: What inventory status should be considered for procurement decisions?

A: The main part (2081203-9) shows 771 pieces in stock as new original inventory. The substitute part (3-1478906-0) shows 740 pieces in stock as new original inventory. Both parts maintain adequate stock levels for immediate procurement. The substitute's active product status ensures continued availability beyond current inventory.
