RFSMAA4JAADQ Equivalent & Substitute Parts
Part Overview
The RFSMAA4JAADQ is an SMA Connector Jack, Female Socket rated for 50 Ohms impedance, designed for panel mount through-hole solder applications. This coaxial RF connector operates across frequencies up to 26.5 GHz and is manufactured by Bulgin in active product status. The connector features a four-hole flange mounting configuration with stainless steel construction and beryllium copper center contacts.
Substitute parts are identified to address application requirements such as alternative mounting hole configurations while maintaining electrical and mechanical compatibility within the SMA connector family.

Engineering Selection Recommendations
All three parts—RFSMAA4JAADQ, RFSMAA4JCCDQ, and RFSMAA2JEGDQ—are active products manufactured by Bulgin with ROHS3 compliance and identical electrical specifications. Selection between these parts is determined by panel mounting hole requirements:
RFSMAA4JAADQ and RFSMAA4JCCDQ are functionally equivalent four-hole flange mount connectors suitable for applications requiring four-point mechanical fastening on the panel.
RFSMAA2JEGDQ provides a two-hole flange mount configuration for applications with different panel layout constraints or spacing requirements.
All parts maintain 50 Ohm impedance, support frequencies to 26.5 GHz, and operate across the -65°C to 165°C temperature range. Component selection should be based on panel hole spacing and mounting geometry requirements specific to the application.
Frequently Asked Questions (FAQ)
Q: Can RFSMAA2JEGDQ be used as a direct replacement for RFSMAA4JAADQ?
A: RFSMAA2JEGDQ is electrically and thermally equivalent to RFSMAA4JAADQ. The primary difference is the mounting hole configuration: two holes versus four holes. Substitution is valid only if the panel layout accommodates the two-hole flange design.
Q: Are there electrical performance differences between the four-hole and two-hole variants?
A: No. Both mounting configurations deliver identical electrical performance across all specified parameters including impedance, frequency response, voltage rating, and operating temperature range.
Q: What is the significance of the mounting hole configuration?
A: The mounting hole configuration determines how the connector is mechanically secured to the panel. Four-hole designs provide additional mechanical stability through increased fastening points, while two-hole designs accommodate panels with different hole spacing or layout requirements.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. RFSMAA4JAADQ, RFSMAA4JCCDQ, and RFSMAA2JEGDQ are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
Q: What is the maximum operating frequency for these connectors?
A: All three parts support operation up to 26.5 GHz, making them suitable for high-frequency RF applications within this bandwidth.
Q: Can these connectors be used interchangeably in existing designs?
A: Electrical interchangeability is confirmed. Mechanical interchangeability depends on panel hole spacing and mounting geometry. Verify that the selected mounting hole configuration matches the application's panel design before implementation.
