Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R125222000W are classified as parametric equivalents based on the following critical parameters that determine functional interchangeability:

Core Electrical Parameters:

• Connector style (SMA)
• Connector type (Jack, Female Socket)
• Impedance (50 Ohms)
• Frequency maximum rating (18 GHz)
• Operating temperature range (-65°C ~ 105°C)

Core Mechanical Parameters:

• Contact termination method (Solder)
• Shield termination method (Solder)
• Mounting type (Free Hanging/In-Line)
• Cable group compatibility (RG-405 .085" Semi Rigid)
• Fastening type (Threaded)
• Number of ports (1)

Material and Construction Parameters:

• Center contact material (Beryllium Copper)
• Body material (Stainless Steel)
• Dielectric material (Polytetrafluoroethylene/PTFE)
• Body finish (Gold)
• Center contact plating (Gold)
• Housing color (Gold)

All identified substitute parts maintain these core parameters. Variations in voltage rating, packaging format, insertion loss specification, and regulatory compliance status are noted but do not preclude functional substitution when application requirements are met.

Parameter Comparison

Engineering Selection Recommendations

R125222000W (Primary Part): The Radiall USA R125222000W is the specified part number and maintains full ROHS3 compliance with a voltage rating of 335 V. This part is supplied in bulk packaging and is currently in active production with 764 units in stock.

R125222000 (Radiall Equivalent): This part is functionally equivalent to R125222000W with identical electrical and mechanical specifications. The primary difference is packaging format (box versus bulk) and a reduced voltage rating of 250 V. This part is ROHS3 compliant and maintains active production status with 1119 units in stock. Selection of this part is appropriate when box packaging is required and the 250 V voltage rating meets application requirements.

1046286-1 (TE Connectivity Aerospace, Defense and Marine): This TE Connectivity part maintains all core electrical and mechanical parameters with a 335 V voltage rating matching the primary part. The part is active in production with 995 units in stock. RoHS status is listed as not applicable. Insertion loss is specified at 0.3 dB. This part is suitable for applications where TE Connectivity sourcing is preferred or required.

1050859-1 (TE Connectivity AMP Connectors): This TE Connectivity part is supplied in bulk packaging and maintains all core electrical and mechanical parameters with a 335 V voltage rating. The part includes 2 pieces per unit (1 connector and 1 contact) and is ROHS3 compliant with REACH affected status. Insertion loss is specified at 0.3 dB. This part is active in production with 1202 units in stock and is suitable for applications requiring bulk packaging and TE Connectivity sourcing.

Frequently Asked Questions (FAQ)

Q: Can R125222000 be used as a direct substitute for R125222000W?

A: R125222000 is functionally equivalent for applications where the 250 V voltage rating is sufficient. Both parts share identical connector style, impedance, termination method, mounting type, frequency rating, and operating temperature range. The primary difference is packaging format (box versus bulk). Verify that your application voltage requirements do not exceed 250 V before substitution.

Q: What is the difference between the Radiall and TE Connectivity substitute parts?

A: All substitute parts maintain identical core electrical and mechanical specifications including SMA jack configuration, 50 ohm impedance, solder termination, 18 GHz frequency rating, and -65°C to 105°C operating temperature. The differences are manufacturer source, packaging format, and regulatory compliance documentation. TE Connectivity parts 1046286-1 and 1050859-1 both specify 0.3 dB insertion loss, while this parameter is not specified for Radiall parts.

Q: Are all substitute parts ROHS3 compliant?

A: R125222000W, R125222000, and 1050859-1 are all ROHS3 compliant. Part 1046286-1 lists RoHS status as not applicable. Verify compliance requirements for your specific application before selection.

Q: What does the packaging difference between bulk and box mean for component selection?

A: Bulk packaging typically indicates loose components supplied in larger quantities without individual packaging. Box packaging indicates components are packaged in smaller quantities with protective boxing. Selection between R125222000W (bulk) and R125222000 (box) depends on your procurement and inventory management requirements. Both parts are electrically and mechanically identical except for voltage rating.

Q: Can I use 1050859-1 which includes 2 pieces per unit?

A: Part 1050859-1 is supplied as a kit containing 1 connector and 1 contact. This part is functionally equivalent to the main part and can be used as a substitute. Verify that the inclusion of the additional contact component meets your assembly requirements.

Q: What is the significance of the 335 V versus 250 V voltage rating difference?

A: The voltage rating indicates the maximum voltage the connector can safely handle. R125222000W, 1046286-1, and 1050859-1 are rated for 335 V, while R125222000 is rated for 250 V. Selection of the 250 V rated part is appropriate only when your application voltage does not exceed this limit. For applications requiring higher voltage capability, select parts with 335 V rating.

Q: Are all substitute parts suitable for RG-405 semi-rigid cable?

A: All substitute parts are specified for RG-405 (.085" semi-rigid) cable group compatibility. This parameter is consistent across all parts and does not differentiate substitution options.

Q: What is the mating cycle rating and why is it important?

A: All parts are rated for 500 mating cycles, indicating the connector can withstand 500 connect/disconnect operations before performance degradation. This specification is identical across all parts and does not affect substitution decisions.
