MMCXV-J-C-HF-ST-CA2 Equivalent & Substitute Parts

Part Overview

The MMCXV-J-C-HF-ST-CA2 is an MMCX (V) Connector Jack, Female Socket manufactured by Samtec Inc. This coaxial RF connector is designed for free hanging (in-line) applications with solder termination on the center contact and crimp termination on the shield. The connector operates at 50 Ohms impedance with a maximum frequency rating of 6 GHz and supports RG-178 cable group compatibility.

The MMCXV-J-C-HF-ST-CA2 carries a "Not For New Designs" product status, indicating that Samtec Inc. has designated this part as obsolete or superseded. For new design implementations and ongoing production requirements, identifying equivalent substitute parts with active product status is necessary to ensure long-term supply chain reliability and design continuity.
