Engineering Selection Recommendations

The Amphenol SV Microwave 2950-6081 serves as the direct substitute for the obsolete TE Connectivity AMP Connectors 1052421-1 based on complete parameter equivalence across all critical electrical and mechanical specifications. The substitute part maintains identical impedance, frequency rating, contact materials, and termination methods, ensuring functional interchangeability in 50 Ohm RF applications.

The 2950-6081 offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The part carries ROHS3 compliance, representing an updated regulatory standard compared to the original RoHS Compliant designation of the 1052421-1. The REACH Unaffected status of the substitute part indicates improved regulatory positioning for new designs and long-term system support.

Both parts are rated for identical operating temperature ranges and mating cycle specifications, confirming mechanical and thermal compatibility. The gold plating on both body finish and center contacts ensures consistent electrical performance and corrosion resistance across the substitution.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol SV Microwave 2950-6081 be used as a direct replacement for the TE Connectivity 1052421-1 in existing assemblies?

A: Yes. The 2950-6081 meets all mandatory electrical and mechanical parameters of the 1052421-1, including SMA connector style, 50 Ohm impedance, female socket configuration, solder cup termination, panel mount flange, and 18 GHz frequency rating. The parts are functionally equivalent for RF applications.

Q: What is the difference between "Receptacle" and "Jack" terminology in the connector type field?

A: Both designations refer to the female socket configuration of the SMA connector. The terminology difference reflects manufacturer naming conventions but does not indicate functional or mechanical differences. Both parts accept the same male SMA plug connectors.

Q: Are there any compliance differences between the two parts?

A: The 2950-6081 carries ROHS3 compliance, which represents a more current regulatory standard than the RoHS Compliant designation of the 1052421-1. The 2950-6081 is REACH Unaffected, indicating it does not contain substances of very high concern listed under REACH regulations, whereas the 1052421-1 is REACH Affected. These differences favor the substitute part for new designs and long-term procurement.

Q: Do both parts support the same operating temperature range?

A: The 1052421-1 is rated for -65°C to 125°C operation. The 2950-6081 does not specify an operating temperature range in the provided data. Verify temperature requirements against application specifications before selection.

Q: What is the inventory status of these parts?

A: The TE Connectivity 1052421-1 has 676 pieces in stock as new original inventory. The Amphenol SV Microwave 2950-6081 has 912 pieces in stock as new original inventory in bulk packaging. The substitute part offers higher availability.

Q: Are the solder cup terminations compatible with the same PCB assembly processes?

A: Both parts feature solder cup termination with solder shield termination, indicating compatibility with standard wave soldering and reflow processes used for RF connector assembly. No process modifications are required when substituting between these parts.

Q: What is the mating cycle rating for both connectors?

A: Both the 1052421-1 and 2950-6081 are rated for 500 mating cycles, indicating identical mechanical durability and connector life expectancy in applications involving repeated connection and disconnection.
