APH-SMAP-TNCJ Equivalent & Substitute Parts

Part Overview

The APH-SMAP-TNCJ is a coaxial adapter connector manufactured by Amphenol RF that converts between SMA Plug (male pin) and TNC Jack (female socket) configurations. This adapter operates at 50 Ohms impedance and supports frequencies up to 11 GHz, making it suitable for RF and microwave applications requiring series conversion between SMA and TNC connector types.

The APH-SMAP-TNCJ is classified as Obsolete. Identifying equivalent substitute parts is necessary to ensure continued availability for system maintenance, repair, and new production builds where this adapter specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APH-SMAP-TNCJ is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Adapter Series: SMA to TNC
• Adapter Type: Plug to Jack
• Center Gender: Female to Male
• Impedance: 50 Ohms
• Frequency - Max: 11 GHz
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded, Threaded
• Body Material: Brass
• Body Finish: Nickel
• Center Contact Material: Phosphor Bronze
• Center Contact Plating: Gold
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Operating Temperature: -65°C ~ 165°C

The substitute part 242124 meets all mandatory matching parameters and is therefore a direct functional equivalent to the APH-SMAP-TNCJ.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 242124 is a direct functional equivalent to the APH-SMAP-TNCJ across all critical electrical and mechanical parameters. Selection between these parts is determined by product status and regulatory compliance considerations:

APH-SMAP-TNCJ (Obsolete): This part number is classified as Obsolete and carries RoHS Compliant certification. It is suitable for applications where legacy part number traceability is required or where existing inventory must be utilized.

242124 (Active): This part number is classified as Active and carries ROHS3 Compliant certification with REACH Affected status. This part is the current production equivalent and is recommended for new designs, production builds, and system maintenance where component availability is a priority. The Active status ensures continued supply chain access and manufacturer support.

Both parts are manufactured by Amphenol RF and maintain identical electrical performance, mechanical form factor, and environmental specifications. Selection should be based on supply chain requirements, regulatory documentation needs, and production timeline considerations.

Frequently Asked Questions (FAQ)

Q: Can 242124 be used as a direct replacement for APH-SMAP-TNCJ?

A: Yes. The 242124 is a direct functional equivalent. All electrical parameters (impedance, frequency range, center gender configuration), mechanical parameters (adapter type, mounting style, fastening type), and material specifications (body material, plating, dielectric) are identical between the two parts.

Q: What is the difference between APH-SMAP-TNCJ and 242124?

A: The primary differences are product status and regulatory compliance. APH-SMAP-TNCJ is Obsolete with RoHS Compliant certification. The 242124 is Active with ROHS3 Compliant certification and REACH Affected status. Functionally and mechanically, the parts are equivalent.

Q: Why is APH-SMAP-TNCJ listed as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this part number. The 242124 serves as the current production equivalent and should be used for new applications and ongoing supply requirements.

Q: Are there packaging differences between these parts?

A: Yes. The APH-SMAP-TNCJ packaging is not specified in the available data. The 242124 is packaged in Bag format. Packaging differences do not affect electrical or mechanical performance.

Q: What does ROHS3 Compliant mean compared to RoHS Compliant?

A: ROHS3 represents the current version of the Restriction of Hazardous Substances directive and includes updated substance restrictions. Both certifications indicate compliance with hazardous substance limitations, with ROHS3 representing the more current regulatory standard.

Q: Can these adapters be used in applications requiring frequencies above 11 GHz?

A: No. Both APH-SMAP-TNCJ and 242124 are specified for maximum frequency of 11 GHz. Applications requiring higher frequency operation require different adapter specifications.

Q: What is the impedance specification for these adapters?

A: Both adapters are specified at 50 Ohms impedance, which is the standard impedance for RF and microwave coaxial systems.

Q: Are these adapters suitable for outdoor or high-temperature applications?

A: Both adapters support operating temperatures from -65°C to 165°C, making them suitable for a wide range of environmental conditions including outdoor installations and elevated temperature environments within this range.
