Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitutes (Highest Compatibility):

The parts 1052982-1 and 1045390-1, both manufactured by TE Connectivity Aerospace, Defense and Marine, are parametric equivalents to the original 1052986-1. These components maintain identical electrical specifications including 18 GHz maximum frequency, 335 V voltage rating, and -65°C to 125°C operating temperature range. Both parts are currently in active product status with ROHS3 compliance certification. The 1052982-1 is available in bulk packaging with 909 units in stock, while 1045390-1 offers insertion loss specification of 0.35 dB. These substitutes provide the most direct replacement path for the obsolete original part.

Compatible Substitutes with Frequency Derating:

The Amphenol SV Microwave SF2960-6025 and Amphenol RF 132275 are functionally compatible substitutes with the constraint that maximum frequency is reduced to 12.4 GHz compared to the original 18 GHz specification. Both parts maintain all other critical parameters including 50 Ohm impedance, solder termination, panel mount right angle configuration, and 500 mating cycles. The SF2960-6025 is available in bulk packaging with 1178 units in stock. The 132275 features an extended operating temperature range of -65°C to 165°C and is available in bag packaging with 1002 units in stock. These substitutes are suitable for applications operating below 12.4 GHz.

Alternative Substitute with Connector Type Variation:

The Cinch Connectivity Solutions 142-1711-016 is classified as a jack-type female socket rather than a receptacle, though it maintains all other critical electrical and mechanical parameters. This part operates at the full 18 GHz frequency specification with 335 V voltage rating and -65°C to 165°C operating temperature range. The part is RoHS Compliant and available in bulk packaging with 699 units in stock. Connector type variation requires mechanical interface verification before deployment.

Compliance and Availability Considerations:

All substitute parts maintain RoHS compliance certification (either RoHS Compliant or ROHS3 Compliant). The TE Connectivity Aerospace, Defense and Marine variants (1052982-1 and 1045390-1) are preferred for applications requiring REACH Affected status consistency with the original part. All substitutes are currently in active product status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can SF2960-6025 or 132275 be used as direct replacements for 1052986-1 in all applications?

A: These parts are compatible substitutes for applications operating at frequencies up to 12.4 GHz. The original 1052986-1 is rated to 18 GHz. If your application requires operation above 12.4 GHz, use 1052982-1, 1045390-1, or 142-1711-016 instead.

Q: What is the difference between 1052982-1 and 1045390-1?

A: Both parts are parametric equivalents manufactured by TE Connectivity Aerospace, Defense and Marine with identical electrical specifications. The 1045390-1 provides insertion loss specification of 0.35 dB. The 1052982-1 is available in bulk packaging. Both are suitable direct replacements for the obsolete 1052986-1.

Q: Why is 142-1711-016 listed as a substitute if it is a jack type rather than a receptacle?

A: The 142-1711-016 maintains all critical electrical parameters and mechanical mounting characteristics. The connector type designation (jack versus receptacle) refers to internal contact geometry. Compatibility depends on the mating connector type in your application. Verify that your mating connector is compatible with a jack-type female socket before selection.

Q: Does the difference in body material between stainless steel and brass affect RF performance?

A: Both stainless steel and brass are acceptable materials for 50 Ohm SMA connectors. The electrical performance is determined by impedance matching and dielectric material (PTFE in all cases). Body material selection affects mechanical durability and environmental resistance. Stainless steel offers superior corrosion resistance; brass with gold plating provides excellent contact reliability.

Q: Are there temperature range limitations when substituting with 132275 or 142-1711-016?

A: The 132275 and 142-1711-016 both support extended operating temperature range of -65°C to 165°C, which exceeds the original 1052986-1 specification of -65°C to 125°C. These parts are suitable for applications across the full original temperature range and beyond.

Q: What is the significance of MSL (Moisture Sensitivity Level) differences?

A: The original 1052986-1 and most substitutes are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling. The SF2960-6025 is rated Not Applicable, indicating no moisture sensitivity concern. This parameter does not affect substitution compatibility.

Q: Can I use these substitutes interchangeably in production?

A: The TE Connectivity parts (1052982-1 and 1045390-1) are direct equivalents and fully interchangeable. The Amphenol and Cinch parts are compatible substitutes with the noted frequency and connector type considerations. Verify packaging requirements and inventory availability for your production volume before committing to a specific substitute.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both certifications indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current version of the directive. Both are acceptable for applications requiring RoHS compliance. The original 1052986-1 is RoHS Compliant; most substitutes are ROHS3 Compliant, representing current manufacturing standards.

Q: Are all substitute parts available in the same packaging as the original?

A: Packaging varies by substitute. The original 1052986-1 packaging is not specified. Substitutes are available in bulk, bag, or unspecified packaging. Packaging does not affect electrical or mechanical function. Verify packaging requirements for your procurement and assembly processes.
