Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1051852-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: SMA
• Impedance: 50 Ohms
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded
• Frequency - Max: 12.4 GHz
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Operating Temperature Range: -65°C ~ 165°C
• Voltage Rating: 500 V
• Mating Cycles: 500

Connector Type Consideration: The 1051852-1 is a Jack (Female Socket). Direct substitutes must maintain the same connector gender and socket configuration to ensure mating compatibility with existing SMA Plug (Male Pin) connectors in the system.

Termination Method: The original part features solder termination for both contact and shield. Substitute parts with alternative termination methods (crimp) represent functional alternatives for new designs but require circuit board redesign and assembly process modification.

Parameter Comparison

Engineering Selection Recommendations

CONSMA011-R58 (TE Connectivity Linx): This part is the primary equivalent for direct replacement of the 1051852-1. Both components are manufactured by TE Connectivity, maintain identical SMA connector style, 50 Ohm impedance, 12.4 GHz frequency rating, and operating temperature range of -65°C to 165°C. Both feature solder contact termination and 500 mating cycles. The CONSMA011-R58 is classified as Active product status, ensuring ongoing availability and supply chain continuity. RoHS compliance is maintained. The primary difference is shield termination method (crimp versus solder) and body material composition (brass versus stainless steel), which do not affect electrical performance in standard RF applications. This part is suitable for direct board-level substitution in existing designs.

2900-6001 (Amphenol SV Microwave): This part represents a functional alternative for new design implementations only. The connector type is Plug (Male Pin) rather than Jack (Female Socket), making it incompatible with existing mating interfaces designed for the 1051852-1. The 2900-6001 employs crimp termination for both contact and shield, requiring circuit board redesign and assembly process modification. The part is Active status and ROHS3 compliant. Operating temperature and voltage rating specifications are not provided for this component. This part is not suitable for direct replacement but may be considered for new system designs where connector gender and termination method can be accommodated.

Frequently Asked Questions (FAQ)

Q: Can the CONSMA011-R58 be used as a direct replacement for the 1051852-1 on existing circuit boards?

A: The CONSMA011-R58 is electrically and mechanically compatible for direct board-level substitution. Both parts maintain SMA Jack (Female Socket) configuration, 50 Ohm impedance, 12.4 GHz frequency rating, and identical operating temperature range. The solder contact termination is compatible with existing assembly processes. The shield termination difference (crimp versus solder) does not prevent installation; however, assembly procedures may require adjustment based on your manufacturing process specifications.

Q: Why is the 2900-6001 listed as an alternative if it has a different connector type?

A: The 2900-6001 is included as a functional alternative for new design applications where system architecture can accommodate a Plug (Male Pin) connector instead of a Jack (Female Socket). This part maintains the same SMA style, 50 Ohm impedance, and 12.4 GHz frequency rating. It is not suitable for direct replacement in existing systems but represents a viable option for new RF coaxial connector implementations.

Q: What are the cable compatibility differences between these parts?

A: The 1051852-1 supports cable groups RG-55, 58, 141, 142, 223, 303, and 400. The CONSMA011-R58 is specified for RG-58 cable. The 2900-6001 supports RG-55, 142, 223, and 400 cables. Cable selection must align with the specific connector part number used in your application.

Q: Are there compliance or regulatory differences between these parts?

A: All three parts are RoHS compliant. The 1051852-1 and CONSMA011-R58 are RoHS Compliant. The 2900-6001 is ROHS3 Compliant, representing a more recent compliance standard. The 1051852-1 is REACH Affected, while the CONSMA011-R58 is REACH Unaffected. All parts carry EAR99 ECCN classification and 8536.69.4010 HTSUS code.

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

A: Both the 1051852-1 and CONSMA011-R58 carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. The 2900-6001 carries Not Applicable MSL rating. This parameter does not affect substitution compatibility but indicates storage and handling requirements are equivalent between the primary part and its direct equivalent.

Q: Can termination method differences affect RF performance?

A: Both solder and crimp termination methods, when properly executed, deliver equivalent RF performance at the specified 12.4 GHz frequency and 50 Ohm impedance. The termination method difference between the 1051852-1 (solder) and CONSMA011-R58 (crimp shield) does not degrade electrical characteristics. Assembly process and quality control procedures must align with the selected termination method.
