FK1FLG Equivalent & Substitute Parts

Part Overview

The FK1FLG is an SMB Fakra Connector Jack, Female Socket manufactured by Taoglas Limited, designed for 50 Ohm coaxial RF applications. This connector operates at frequencies up to 6 GHz and is configured for free hanging (in-line) crimp termination with RG-174 and RG-316 cable groups. The part is classified as Active product status with ROHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component procurement, inventory management, or design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FK1FLG are identified based on strict electrical and mechanical parameter equivalence. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Connector Style: SMB, Fakra
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency - Max: 6 GHz
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Shield Termination: Crimp
• Cable Group: RG-174, RG-316
• Fastening Type: Latch Lock
• Operating Temperature Range: -40°C ~ 105°C
• Mating Cycles: 25
• Features: Code L
• RoHS Status: ROHS3 Compliant

The substitute part FK1FLDK matches all critical parameters and maintains identical electrical performance characteristics and mechanical compatibility with the FK1FLG.

Parameter Comparison

Engineering Selection Recommendations

Both FK1FLG and FK1FLDK are Active product status components manufactured by Taoglas Limited. Selection between these parts is based on inventory availability and procurement requirements rather than technical performance differences.
