FKDFZG Equivalent & Substitute Parts

Part Overview

The FKDFZG is a dual-port SMB Fakra Code Z coaxial connector manufactured by Taoglas Limited, designed for RF applications requiring 50-ohm impedance. This female socket connector features crimp termination for both contact and shield, free-hanging in-line mounting, and operates across the -40°C to 105°C temperature range. The part is Active in product status and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where port configuration or specific connector variants are interchangeable.

Substitute Part Grouping Explanation

Substitution of FKDFZG is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

Impedance: 50 Ohms
Frequency - Max: 6 GHz
Contact Termination: Crimp
Shield Termination: Crimp

Mechanical Parameters:

Connector Style: SMB, Fakra
Connector Type: Jack, Female Socket
Mounting Type: Free Hanging (In-Line)
Fastening Type: Latch Lock
Cable Group: RG-174, 316
Features: Code Z

Environmental & Compliance Parameters:

Operating Temperature: -40°C ~ 105°C

Substitute parts FK1FZDK, FK1FZG, and FKDFZDK maintain all critical electrical and mechanical parameters. The primary distinction is the number of ports: FKDFZG and FKDFZDK feature dual ports (2), while FK1FZDK and FK1FZG feature single ports (1). Single-port variants are substitutable in applications requiring only one connection point.

Engineering Selection Recommendations

All substitute parts—FKDFZDK, FK1FZDK, and FK1FZG—are Active products manufactured by Taoglas Limited with identical ROHS3 compliance and REACH Unaffected status. Selection between dual-port (FKDFZG, FKDFZDK) and single-port (FK1FZDK, FK1FZG) variants depends on application requirements for the number of connection points.

FKDFZDK is the direct dual-port equivalent to FKDFZG, maintaining identical electrical, mechanical, and environmental specifications. FK1FZDK and FK1FZG are single-port alternatives suitable for applications requiring only one SMB Fakra Code Z connection. All parts share identical impedance, frequency rating, termination methods, and temperature operating range.

Frequently Asked Questions (FAQ)

Q: Can FK1FZDK or FK1FZG replace FKDFZG in all applications?

A: FK1FZDK and FK1FZG are electrically and mechanically equivalent to FKDFZG but feature single ports instead of dual ports. Substitution is valid only in applications requiring a single connection point. Applications requiring dual simultaneous connections must use FKDFZG or FKDFZDK.

Q: What is the primary difference between FKDFZG and FKDFZDK?

A: FKDFZG and FKDFZDK are functionally equivalent dual-port SMB Fakra Code Z connectors. Both maintain identical electrical specifications (50 ohms, 6 GHz maximum frequency), mechanical configuration (crimp termination, latch lock fastening), and environmental ratings (-40°C to 105°C, 25 mating cycles).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. FKDFZDK, FK1FZDK, and FK1FZG are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status, matching FKDFZG compliance requirements.

Q: What cable types are compatible with these connectors?

A: All parts in this substitution group support RG-174 and RG-316 cable groups with crimp termination for both contact and shield.

Q: Can single-port variants be used in dual-port applications?

A: No. Applications requiring simultaneous dual connections must use dual-port variants (FKDFZG or FKDFZDK). Single-port variants (FK1FZDK, FK1FZG) provide only one connection point and cannot fulfill dual-connection requirements.
