APH-SMAP-MMCXP Equivalent & Substitute Parts

Part Overview

The APH-SMAP-MMCXP is a coaxial adapter connector manufactured by Amphenol RF that converts between SMA Plug (Male Pin) and MMCX Plug (Male Pin) interfaces. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 6 GHz and is designed for free-hanging, in-line mounting applications.

The APH-SMAP-MMCXP carries an Obsolete product status. Identifying equivalent substitute parts is necessary to ensure continued availability for system integration, maintenance, and new production builds where this adapter specification is required.

Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Adapter Series: SMA to MMCX
• Adapter Type: Plug to Plug
• Center Gender: Male to Male
• Impedance: 50 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Snap-On, Threaded
• Frequency - Max: 6 GHz
• Operating Temperature Range: -65°C ~ 165°C
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Body Material: Brass
• Body Finish: Gold
• Center Contact Plating: Gold

The substitute part 242142 meets all mandatory matching parameters and is therefore classified as a direct equivalent for the APH-SMAP-MMCXP.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 242142 is a direct functional equivalent to the APH-SMAP-MMCXP. Both parts are manufactured by Amphenol RF and share identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The APH-SMAP-MMCXP is classified as Obsolete, while 242142 is Active. Selection of 242142 ensures access to current production inventory and ongoing manufacturer support.

Compliance Status: The APH-SMAP-MMCXP carries RoHS Compliant certification. The substitute part 242142 carries ROHS3 Compliant certification, which represents a higher compliance standard. Additionally, 242142 is REACH Affected, indicating compliance with European chemical safety regulations.

Material Specification Variance: The center contact material differs between the two parts. The APH-SMAP-MMCXP uses Brass, while 242142 uses Beryllium Copper. Both materials are acceptable for 50 Ohm coaxial adapter applications and do not affect electrical performance or mechanical compatibility within the specified operating parameters.

Packaging: The APH-SMAP-MMCXP packaging is not specified in available documentation. The substitute part 242142 is supplied in Bag packaging, suitable for standard component handling and storage.

Frequently Asked Questions (FAQ)

Q: Can 242142 be used as a direct replacement for APH-SMAP-MMCXP?

A: Yes. Both parts are SMA Plug to MMCX Plug adapters with identical electrical specifications (50 Ohms, 6 GHz maximum frequency), mechanical configuration (straight, free-hanging, snap-on threaded fastening), and operating temperature range (-65°C ~ 165°C). The parts are functionally interchangeable.

Q: What is the difference in center contact material between these parts?

A: The APH-SMAP-MMCXP uses Brass center contacts, while 242142 uses Beryllium Copper. Both materials are suitable for RF coaxial adapter applications and maintain equivalent electrical performance within the specified frequency and impedance parameters.

Q: Why is the APH-SMAP-MMCXP marked as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this part number. The substitute part 242142 is currently in Active production status, ensuring availability for new applications and ongoing supply.

Q: Does the RoHS3 compliance of 242142 affect compatibility?

A: No. ROHS3 compliance is a regulatory certification indicating adherence to European Restriction of Hazardous Substances standards. It does not alter the electrical or mechanical performance of the adapter. ROHS3 represents a higher compliance standard than RoHS Compliant.

Q: Are there any frequency or impedance differences between these adapters?

A: No. Both the APH-SMAP-MMCXP and 242142 operate at 50 Ohms impedance with a maximum frequency rating of 6 GHz. They are electrically equivalent across the full specified operating range.

Q: What is the packaging difference?

A: The APH-SMAP-MMCXP packaging is not specified in available documentation. The substitute part 242142 is supplied in Bag packaging, which is standard for RF coaxial connectors and adapters.

Q: Can these adapters be used in high-temperature applications?

A: Yes. Both adapters are rated for operating temperatures from -65°C to 165°C, making them suitable for industrial and aerospace applications requiring extended temperature ranges.

Q: Is the REACH compliance of 242142 important for my application?

A: REACH compliance is required for products sold or used within the European Union. If your application involves EU distribution or operation, the REACH Affected status of 242142 ensures regulatory compliance. If your application is outside the EU, this certification does not affect functionality.
