Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1050740-1 is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Connector Style: SMA
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded
• Number of Ports: 1

Secondary Compatibility Criteria:

• Frequency - Max: Must support minimum 18 GHz
• Voltage Rating: Must support minimum 500 V
• Mating Cycles: Must support minimum 500 cycles
• Operating Temperature Range: Must encompass -65°C to 105°C minimum

Termination Considerations: Contact termination methods (Push On, Solder) and shield termination methods (Crimp, Solder) determine application-specific suitability. Parts with different termination methods may serve equivalent functional roles depending on cable assembly requirements.

Cable Compatibility: RG-402 cable group compatibility is maintained across substitute parts, with variations between semi-rigid and flexible configurations based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

SF2902-6005 (Amphenol SV Microwave): This substitute part is active in production and carries ROHS3 compliance certification. It maintains electrical equivalence across impedance, frequency, and port specifications. The primary distinction is contact termination method (Solder versus Push On) and cable configuration (flexible versus semi-rigid RG-402). This part is suitable for applications where solder termination is compatible with cable assembly processes. Operating temperature and voltage rating specifications are not provided for this part.

142-0694-066 (Cinch Connectivity Solutions): This substitute part is active in production and carries ROHS3 compliance certification with REACH Affected status. It maintains push-on contact termination matching the original 1050740-1 specification. The connector supports extended frequency operation to 26.5 GHz and extended operating temperature range to 165°C, both exceeding original specifications. Shield termination is solder-based rather than crimp. This part includes three components (connector, contact, coupling nut) and is compatible with semi-rigid RG-402 cable configuration. Body material is brass with nickel finish and gold-plated center contact.

Both substitute parts satisfy the core electrical and mechanical requirements for SMA 50 Ohm plug connectors in free-hanging configurations. Selection between substitutes depends on termination method compatibility with intended cable assembly and application temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can SF2902-6005 directly replace 1050740-1 in existing assemblies?

A: SF2902-6005 maintains electrical equivalence in impedance, frequency, and connector geometry. However, the contact termination method differs (Solder versus Push On). Direct replacement is possible only if the cable assembly process and connector interface support solder termination. Shield termination is also solder-based rather than crimp.

Q: What is the primary difference between 142-0694-066 and 1050740-1?

A: Both connectors use push-on contact termination and semi-rigid RG-402 cable configuration. The 142-0694-066 provides extended frequency capability (26.5 GHz versus 18 GHz) and extended operating temperature range (-65°C to 165°C versus -65°C to 105°C). Shield termination is solder-based in the substitute. The 142-0694-066 includes additional components (contact and coupling nut) and carries ROHS3 compliance.

Q: Are there voltage rating differences between the substitute parts?

A: The 1050740-1 and 142-0694-066 both specify 500 V voltage rating. The SF2902-6005 does not provide a voltage rating specification in available documentation.

Q: Which substitute part maintains the closest mechanical compatibility?

A: The 142-0694-066 maintains the closest mechanical compatibility, including push-on contact termination, semi-rigid RG-402 cable group, and identical voltage rating. Both parts are housed in silver-colored connectors with threaded fastening and support 500 mating cycles.

Q: What is the significance of the cable group designation (Semi Rigid versus Flexible)?

A: RG-402 semi-rigid cable provides structural rigidity and is used in fixed routing applications. RG-402 flexible cable accommodates dynamic routing and repeated flexing. The 1050740-1 and 142-0694-066 specify semi-rigid configuration, while SF2902-6005 specifies flexible configuration. Cable type selection depends on application mechanical requirements.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. The 1050740-1 is RoHS Compliant. Both SF2902-6005 and 142-0694-066 are ROHS3 Compliant, representing current RoHS standards. All parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications.

Q: What does the MSL rating indicate for these connectors?

A: Moisture Sensitivity Level (MSL) 1 (Unlimited) indicates the connector has unlimited shelf life under normal storage conditions without special moisture control measures. SF2902-6005 lists MSL as Not Applicable, indicating this specification does not apply to that part configuration.
