APH-SMAJ-MCXP Coaxial Connector Adapter - Equivalent & Substitute Parts

Part Overview

The APH-SMAJ-MCXP is a coaxial connector adapter manufactured by Amphenol RF that converts between SMA Jack (Female Socket) and MCX Plug (Male Pin) configurations. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 6 GHz and supports operating temperatures from -65°C to 165°C.

The APH-SMAJ-MCXP is classified as Obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring SMA to MCX conversion functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for coaxial connector adapters is determined by strict alignment of electrical and mechanical parameters. The following criteria establish whether a part qualifies as a functional equivalent:

Critical Substitution Parameters:

• Impedance rating (50 Ohms)
• Adapter series (SMA to MCX conversion capability)
• Center gender configuration (Female to Male)
• Maximum frequency rating (6 GHz minimum)
• Operating temperature range (-65°C ~ 165°C minimum)
• Connector style (Straight, Free Hanging In-Line mounting)
• Fastening mechanism (Snap-On, Threaded)

The substitute part 242127 meets all critical electrical and mechanical parameters required for functional equivalence to the APH-SMAJ-MCXP. Both parts provide identical SMA to MCX conversion functionality with matching impedance, frequency, temperature, and physical specifications.

Engineering Selection Recommendations

APH-SMAJ-MCXP (Obsolete Status): This part is no longer in active production. While 1114 pieces remain in current inventory, long-term availability cannot be assured. The obsolete status necessitates transition planning to alternative sources.

242127 (Active Status): This part is actively manufactured and maintained by Amphenol RF. With 1930 pieces in inventory and active product status, 242127 provides assured long-term availability and supply chain continuity. The part carries ROHS3 Compliant certification and REACH Affected status, meeting current regulatory requirements.

Functional Equivalence: Both parts provide identical electrical performance across all specified parameters: 50 Ohms impedance, 6 GHz maximum frequency, -65°C to 165°C operating temperature range, and matching mechanical specifications for SMA to MCX conversion.

Compliance Consideration: 242127 carries ROHS3 Compliant status compared to RoHS Compliant for the APH-SMAJ-MCXP, indicating alignment with current environmental regulations.

For new designs and ongoing applications, 242127 is the appropriate selection due to active product status and regulatory compliance. For existing inventory management of APH-SMAJ-MCXP, 242127 provides direct functional substitution.

Frequently Asked Questions (FAQ)

Q: Can 242127 directly replace APH-SMAJ-MCXP in existing applications?

A: Yes. Both parts meet identical electrical specifications (50 Ohms, 6 GHz maximum frequency, -65°C to 165°C operating temperature) and mechanical requirements (Straight style, Free Hanging In-Line mounting, Snap-On Threaded fastening). The parts are functionally equivalent for SMA to MCX conversion applications.

Q: What is the key difference between APH-SMAJ-MCXP and 242127?

A: The primary difference is product status. APH-SMAJ-MCXP is Obsolete, while 242127 is Active. Additionally, 242127 carries ROHS3 Compliant and REACH Affected certifications, reflecting current regulatory standards. The connector end orientation is reversed between the two parts: APH-SMAJ-MCXP converts from SMA Jack to MCX Plug, while 242127 converts from MCX Plug to SMA Jack. Both configurations provide equivalent SMA-to-MCX conversion functionality.

Q: Are there packaging differences between these parts?

A: APH-SMAJ-MCXP packaging is not specified in available documentation. 242127 is supplied in Bag packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts support the same frequency range?

A: Yes. Both parts are rated for maximum frequency of 6 GHz and operate across identical temperature ranges (-65°C to 165°C).

Q: Which part should be selected for new designs?

A: 242127 is the appropriate selection for new designs due to Active product status, ensuring long-term availability and supply chain reliability. The part meets current RoHS3 and REACH compliance requirements.

Q: Are the connector materials identical?

A: Yes. Both parts use Brass body with Gold finish, Beryllium Copper center contacts with Gold plating, and PTFE dielectric material. Material specifications are identical across all components.
