RFSMAA2JCEFFGE SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA2JCEFFGE is an SMA connector jack (female socket) manufactured by Bulgin, designed for 50 Ohm RF applications with panel mount, through-hole solder termination. This connector operates across frequencies up to 26.5 GHz and is rated for operating temperatures from -65°C to 165°C. The part is currently active in production with 695 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained, allowing for component interchangeability in circuit designs where specific mounting hole configurations or inventory availability require alternative part selection.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA2JCEFFGE are identified based on strict equivalence of the following critical parameters:

• Connector Style & Type: SMA Jack, Female Socket configuration
• Electrical Specifications: 50 Ohm impedance, 26.5 GHz maximum frequency, 335 V voltage rating
• Termination Method: Solder contact and shield termination
• Mounting Configuration: Panel mount with through-hole solder attachment and flange mounting feature
• Material Composition: Beryllium copper center contact, stainless steel body, polyetherimide dielectric
• Environmental Ratings: -65°C to 165°C operating temperature, 500 mating cycles, RoHS3 compliance

The primary distinction among substitute parts is the mounting hole configuration (2-hole versus 4-hole flange design), which affects panel layout requirements but does not alter electrical performance or RF characteristics. All substitute parts maintain identical electrical and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSMAA2JCEFFGE, RFSMAA2JEGACDD, and RFSMAA4JCCACDD—are active production components with ROHS3 compliance and identical electrical specifications. Selection between these parts is determined by panel mounting hole requirements:

RFSMAA2JCEFFGE and RFSMAA2JEGACDD are direct electrical and mechanical equivalents, both featuring 2-hole flange mounting. These parts are interchangeable for applications requiring 2-hole panel mount configurations.

RFSMAA4JCCACDD provides the same electrical performance and RF characteristics but incorporates a 4-hole flange mounting design. This variant is selected when panel layout or mechanical fastening requirements specify 4-hole mounting geometry.

All parts maintain identical impedance, frequency response, temperature rating, voltage rating, and material specifications. Component selection should be based on panel hole pattern compatibility and current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2JCEFFGE be replaced with RFSMAA2JEGACDD?

A: Yes. Both parts are electrically and mechanically equivalent SMA female jack connectors with 2-hole flange mounting. They share identical impedance (50 Ohms), frequency rating (26.5 GHz), temperature range (-65°C to 165°C), and all material specifications. Substitution is direct for applications using 2-hole panel mount configurations.

Q: What is the difference between the 2-hole and 4-hole variants?

A: The primary difference is the flange mounting hole pattern. RFSMAA2JCEFFGE and RFSMAA2JEGACDD feature 2-hole flanges, while RFSMAA4JCCACDD features 4-hole flanges. All other electrical and RF specifications are identical. Selection depends on panel layout and mechanical fastening requirements.

Q: Are all three parts RoHS compliant?

A: Yes. RFSMAA2JCEFFGE, RFSMAA2JEGACDD, and RFSMAA4JCCACDD are all ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited).

Q: Can RFSMAA4JCCACDD be used in place of RFSMAA2JCEFFGE?

A: Electrical substitution is valid; however, mechanical compatibility depends on panel hole pattern. If the application requires 2-hole mounting, RFSMAA4JCCACDD will not fit without panel modification. If the application can accommodate 4-hole mounting, RFSMAA4JCCACDD provides equivalent RF performance.

Q: What determines whether these parts are substitutable?

A: Substitutability is based on matching connector style (SMA), type (Jack, Female Socket), impedance (50 Ohms), frequency rating (26.5 GHz), termination method (Solder), operating temperature range (-65°C to 165°C), and material composition. Mounting hole configuration is a mechanical consideration that may require panel design verification.

Q: Are there inventory differences between these parts?

A: Yes. RFSMAA2JCEFFGE has 695 units in stock, RFSMAA2JEGACDD has 1172 units, and RFSMAA4JCCACDD has 1066 units. Inventory availability may influence part selection when lead time is a consideration.
