Substitute Part Grouping Explanation

The substitute part 1052982-1 is classified as a parametric equivalent to the main part 1045390-1. Both components share identical electrical and mechanical specifications across all critical parameters that determine RF coaxial connector compatibility and performance. The substitution is valid based on the following matching parameters:

Electrical Compatibility Parameters:

• SMA connector style with 50-ohm impedance
• Maximum frequency rating of 18 GHz
• Voltage rating of 335 V
• Operating temperature range of -65°C to 125°C
• Mating cycle rating of 500 cycles

Mechanical Compatibility Parameters:

• Receptacle, female socket connector type
• Right-angle panel mount configuration with flange mounting feature
• Solder termination for both center contact and shield
• Threaded fastening type
• Extended insulation feature

Material and Construction Parameters:

• Beryllium copper center contact with gold plating
• Stainless steel body construction
• PTFE dielectric material

Compliance Parameters:

• ROHS3 compliant status
• Moisture sensitivity level 1 (unlimited)
• EAR99 export classification
• HTSUS code 8536.69.4010

The primary difference between the parts is packaging configuration, with 1052982-1 supplied in bulk packaging versus the standard packaging of 1045390-1.
