Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1058664-1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Adapter Type: Plug to Jack
• Adapter Series: SMA to N (conversion between SMA and N connector families)
• Convert From: SMA Plug, Male Pin
• Convert To: N Jack, Female Socket
• Center Gender: Female to Male
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded, Threaded
• Dielectric Material: Polytetrafluoroethylene (PTFE)

Compatibility Considerations:

• Frequency maximum rating must support the intended application bandwidth
• Center contact plating (Gold) ensures consistent electrical performance
• Body material and center contact material affect mechanical durability and signal integrity
• RoHS and REACH compliance status determines regulatory acceptability in target markets

The substitute part Amphenol RF 242112 satisfies all mandatory matching parameters while maintaining functional equivalence for SMA-to-N adapter applications.

Engineering Selection Recommendations

Primary Substitute: Amphenol RF 242112

The Amphenol RF 242112 serves as the functional equivalent for the obsolete TE Connectivity 1058664-1. Selection of this substitute is based on the following engineering criteria:

Functional Equivalence: All mandatory adapter parameters align between the two parts, including adapter type, series conversion (SMA to N), connector gender configuration, style, mounting type, and fastening mechanism. Both parts utilize PTFE dielectric material and gold-plated center contacts.

Product Status: The Amphenol RF 242112 maintains active product status, ensuring ongoing availability and supply chain continuity. The TE Connectivity 1058664-1 is classified as obsolete, making continued procurement impractical for new designs and system maintenance.

Regulatory Compliance: Both parts satisfy REACH and RoHS compliance requirements. The Amphenol RF 242112 carries ROHS3 certification, representing the current regulatory standard. Both parts are classified under ECCN EAR99 and HTSUS 8536.69.4010.

Frequency Specification Consideration: The TE Connectivity 1058664-1 specifies a maximum frequency of 18 GHz, while the Amphenol RF 242112 specifies 11 GHz. Applications operating below 11 GHz experience full compatibility. Applications requiring operation between 11 GHz and 18 GHz require frequency-specific evaluation against the Amphenol RF 242112 specifications.

Material Composition Differences: The TE Connectivity 1058664-1 uses stainless steel body with beryllium copper center contact. The Amphenol RF 242112 uses brass body with nickel finish and phosphor bronze center contact. Both material sets provide suitable electrical and mechanical performance for coaxial RF adapter applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 242112 directly replace the TE Connectivity 1058664-1 in all applications?

A: The Amphenol RF 242112 provides functional equivalence for SMA-to-N adapter applications. The primary consideration is frequency range: applications operating at or below 11 GHz experience full compatibility. Applications requiring operation above 11 GHz must evaluate the Amphenol RF 242112 against specific system frequency requirements.

Q: What are the key differences between these two adapter parts?

A: The primary differences are product status (obsolete versus active), maximum frequency rating (18 GHz versus 11 GHz), body material (stainless steel versus brass with nickel finish), and center contact material (beryllium copper versus phosphor bronze). Both parts maintain identical adapter type, connector series conversion, gender configuration, and dielectric material.

Q: Are there packaging differences between the TE Connectivity 1058664-1 and Amphenol RF 242112?

A: The TE Connectivity 1058664-1 packaging is not specified in available documentation. The Amphenol RF 242112 is supplied in bag packaging. Confirm packaging requirements with procurement specifications for your application.

Q: Do both parts meet current regulatory standards?

A: Both parts satisfy REACH and RoHS compliance requirements. The Amphenol RF 242112 carries ROHS3 certification, representing the current regulatory standard. Both parts are classified under ECCN EAR99 for export control purposes.

Q: What is the impedance specification for these adapters?

A: The TE Connectivity 1058664-1 impedance is not specified in available documentation. The Amphenol RF 242112 is rated at 50 Ohms, the standard impedance for RF coaxial connectors and adapters.

Q: Are there operating temperature specifications for these parts?

A: The TE Connectivity 1058664-1 operating temperature range is not specified in available documentation. The Amphenol RF 242112 operates across the temperature range of -65°C to 165°C, suitable for industrial and military RF applications.

Q: What connector types are involved in this adapter conversion?

A: This adapter converts between SMA (SubMiniature version A) and N connector families. The SMA end functions as a plug with male pin, while the N end functions as a jack with female socket. This configuration allows SMA male connectors to mate with N female connectors.
