APH-SMAP-MCXP Equivalent & Substitute Parts

Part Overview

The APH-SMAP-MCXP is a coaxial adapter connector manufactured by Amphenol RF that converts between SMA Plug (Male Pin) and MCX Plug (Male Pin) configurations. This straight-style, free-hanging 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-SMAP-MCXP 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.

Engineering Selection Recommendations

Part 242128 (Amphenol RF)

Part 242128 is a direct electrical and mechanical equivalent to the APH-SMAP-MCXP. Both parts are manufactured by Amphenol RF and satisfy identical functional requirements for SMA-to-MCX plug adapter applications at 50 Ohms impedance and 6 GHz maximum frequency.

The primary distinction between these parts is product status and regulatory compliance:

APH-SMAP-MCXP: Obsolete status, RoHS Compliant
242128: Active status, ROHS3 Compliant

Part 242128 carries Active product status, indicating current manufacturing availability and ongoing supplier support. The ROHS3 compliance designation reflects updated regulatory alignment compared to the RoHS Compliant status of the obsolete part.

Both parts maintain identical electrical performance specifications, material composition, and operating temperature ranges. Selection of part 242128 is appropriate for applications requiring the APH-SMAP-MCXP specification where component availability and regulatory currency are considerations.

Frequently Asked Questions (FAQ)

Q: Can part 242128 be used as a direct replacement for APH-SMAP-MCXP?

A: Yes. Part 242128 meets all electrical and mechanical parameters of the APH-SMAP-MCXP. Both parts provide identical SMA Plug (Male) to MCX Plug (Male) conversion at 50 Ohms impedance with 6 GHz maximum frequency rating and -65°C to 165°C operating temperature range.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?

A: RoHS Compliant indicates conformance to the original Restriction of Hazardous Substances directive. ROHS3 Compliant indicates conformance to the updated RoHS 3 directive (2011/65/EU as amended by 2015/863/EU), which includes additional restricted substances. Part 242128 carries the more current ROHS3 designation.

Q: Are there packaging differences between these parts?

A: APH-SMAP-MCXP packaging is not specified in available documentation. Part 242128 is supplied in Bag packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts support the same frequency range?

A: Yes. Both APH-SMAP-MCXP and 242128 are rated for maximum frequency of 6 GHz and operate across identical temperature ranges from -65°C to 165°C.

Q: Why is APH-SMAP-MCXP marked as Obsolete?

A: Obsolete status indicates the part is no longer in active production. Part 242128 is the active equivalent and is currently manufactured and stocked by Amphenol RF.

Q: Are the connector materials identical between both parts?

A: Yes. Both parts use brass bodies with gold finish, beryllium copper center contacts with gold plating, and polytetrafluoroethylene (PTFE) dielectric material.
