Substitute Part Grouping Explanation

Substitution of the 1052643-1 is determined by strict equivalence across the following critical parameters: SMA connector style, receptacle female socket configuration, 50 Ohm impedance, compression contact termination, screw shield termination, panel mount flange mounting, threaded fastening, and operating temperature range. All substitute parts must maintain these core electrical and mechanical specifications to ensure direct compatibility in RF coaxial connector applications.

The substitute parts are grouped into two categories:

Parametric Equivalent (Same Manufacturer - TE Connectivity): Parts 1052652-1 and 1052962-1 maintain identical electrical specifications and mechanical form factors as the 1052643-1. These parts differ in product status and manufacturing division but preserve all critical substitution parameters.

Cross-Manufacturer Equivalent (Cinch Connectivity Solutions): Part 142-1701-546 provides functional equivalence with identical core parameters. This part operates at a higher maximum frequency (26.5 GHz versus 18 GHz) and features a brass body with nickel finish, representing an enhanced specification alternative.

Engineering Selection Recommendations

Primary Substitute: 1052962-1

The TE Connectivity 1052962-1 is the recommended primary substitute for the obsolete 1052643-1. This part maintains identical electrical and mechanical specifications across all critical parameters including SMA receptacle configuration, 50 Ohm impedance, compression termination, and panel mount flange mounting. The 1052962-1 carries Active product status with ROHS3 compliance and is currently in stock with 1047 units available. The part is qualified to MIL-DTL-83517 military standards. The operating temperature range extends to 105°C maximum, which is lower than the original part's 165°C specification; applications requiring the full -65°C to 165°C range should evaluate alternative options.

Secondary Substitute: 1052652-1

The TE Connectivity 1052652-1 provides parametric equivalence with identical specifications to the 1052643-1 across all core electrical and mechanical parameters. This part is classified as Discontinued at DiGi Electronics and carries ROHS3 compliance. The 1052652-1 maintains the full -65°C to 165°C operating temperature range. Availability is limited to 637 units in stock.

Cross-Manufacturer Alternative: 142-1701-546

The Cinch Connectivity Solutions 142-1701-546 offers functional equivalence with enhanced frequency capability (26.5 GHz versus 18 GHz). This part maintains all core substitution parameters including SMA configuration, 50 Ohm impedance, compression termination, and panel mount mounting. The 142-1701-546 features a brass body with nickel finish and is classified as Active with 1183 units in stock. The connector type designation differs (Jack versus Receptacle) but maintains female socket functionality. This part is suitable for applications where higher frequency performance is beneficial or required.

Frequently Asked Questions (FAQ)

Q: Can the 1052962-1 directly replace the 1052643-1 in all applications?

A: The 1052962-1 provides direct substitution for the 1052643-1 across all core electrical and mechanical parameters. However, the 1052962-1 operating temperature maximum is limited to 105°C compared to the original part's 165°C specification. Applications requiring operation above 105°C must use the 1052652-1 or 142-1701-546 alternatives.

Q: What is the difference between "Receptacle" and "Jack" connector types in the SMA family?

A: Both receptacle and jack designations refer to female socket configurations in SMA connectors. The 142-1701-546 uses the "Jack" terminology while the 1052643-1 uses "Receptacle," but both parts provide identical female socket functionality for mating with male SMA plugs.

Q: Is the 142-1701-546 suitable for applications designed for the 1052643-1?

A: The 142-1701-546 maintains all critical substitution parameters including SMA style, 50 Ohm impedance, compression termination, screw shield termination, panel mount flange mounting, and operating temperature range (-65°C to 165°C). The higher maximum frequency rating (26.5 GHz) represents an enhanced specification. The brass body with nickel finish differs from the stainless steel body of the original part but does not affect electrical compatibility.

Q: What is the significance of the MIL-DTL-83517 qualification on the 1052962-1?

A: The MIL-DTL-83517 qualification indicates that the 1052962-1 meets military standards for SMA connectors. This qualification provides assurance of manufacturing consistency and performance reliability for defense and aerospace applications.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts carry RoHS compliance certifications. The 1052643-1, 1052652-1, and 1052962-1 are RoHS Compliant or ROHS3 Compliant. The 142-1701-546 is RoHS Compliant. All parts maintain MSL Rating 1 (Unlimited) moisture sensitivity.

Q: What packaging options are available for these substitute parts?

A: The 1052643-1 and 1052652-1 packaging is not specified in available documentation. The 1052962-1 is supplied in Bulk packaging. The 142-1701-546 is supplied in Bulk packaging with 1183 units currently in stock.

Q: Can the 1052652-1 be used as a long-term substitute despite its discontinued status?

A: The 1052652-1 is classified as Discontinued at DiGi Electronics but maintains 637 units in current inventory. This part provides identical specifications to the 1052643-1 including the full -65°C to 165°C operating temperature range. For applications requiring the extended temperature range, the 1052652-1 is a viable option while inventory is available. The 1052962-1 is recommended as the primary long-term substitute due to its Active product status.
