Engineering Selection Recommendations

Primary Selection: 1052962-1

The 1052962-1 is the recommended primary selection for new designs and procurement. This part maintains Active product status with established supply chain availability of 1047 pieces in current inventory. The part is fully compliant with ROHS3 and REACH regulations, suitable for aerospace, defense, and marine applications per the Military MIL-DTL-83517 series classification.

Alternative Selection: 1052652-1

The 1052652-1 serves as a parametric equivalent substitute when the primary part becomes unavailable. This part is electrically and mechanically identical to the 1052962-1 across all RF performance parameters, contact materials, and mechanical interfaces. The substitute part features an extended operating temperature range of -65°C to 165°C compared to the primary part's -65°C to 105°C range, providing additional thermal capability for high-temperature applications.

The 1052652-1 carries Discontinued at DiGi Electronics status, indicating limited future availability. Current inventory of 637 pieces supports near-term substitution requirements. Both parts maintain identical compliance certifications and material specifications.

Selection Criteria:

Use 1052962-1 for standard applications within the -65°C to 105°C operating range with priority on supply continuity.

Use 1052652-1 for applications requiring extended high-temperature operation to 165°C or when 1052962-1 becomes unavailable, provided application thermal requirements do not exceed 165°C.

Frequently Asked Questions (FAQ)

Q: Are the 1052962-1 and 1052652-1 electrically interchangeable?

A: Yes. Both parts are SMA receptacle connectors with identical 50 ohm impedance, 18 GHz frequency capability, compression contact termination, and gold-plated beryllium copper center contacts. Electrical performance is equivalent across the specified frequency range.

Q: What is the primary difference between these two parts?

A: The operating temperature range differs. The 1052962-1 operates from -65°C to 105°C, while the 1052652-1 operates from -65°C to 165°C. All other electrical, mechanical, and material specifications are identical.

Q: Can I use the 1052652-1 in place of the 1052962-1 in existing designs?

A: Yes. The 1052652-1 is mechanically and electrically compatible with the 1052962-1. Panel mount flange configuration, threaded fastening, and compression contact termination are identical. The extended temperature range of the substitute part does not create compatibility issues in standard temperature applications.

Q: What does "Discontinued at DiGi Electronics" mean for the 1052652-1?

A: This status indicates that the 1052652-1 is no longer actively distributed through DiGi Electronics channels. However, 637 pieces remain in current inventory. This part should be considered for immediate procurement if required, as future availability through standard distribution channels is limited.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 1052962-1 and 1052652-1 are ROHS3 Compliant and REACH Affected. Both parts meet current environmental and hazardous substance regulations for aerospace, defense, and marine applications.

Q: What mounting configurations do these connectors support?

A: Both parts feature panel mount configuration with flange mounting feature and threaded fastening. The flange provides mechanical stability for panel-mounted RF applications. No alternative mounting configurations are available for these part numbers.

Q: How many mating cycles are rated for these connectors?

A: Both parts are rated for 500 mating cycles. This specification applies to the compression contact interface and represents the expected operational life under normal connection and disconnection cycles.

Q: Can these connectors be used in hermetically sealed applications?

A: Yes. Both parts include the feature designation "For Hermetically Sealed Pin," indicating compatibility with hermetically sealed connector pin configurations used in sealed RF assemblies.
