FKDFZDK Equivalent & Substitute Parts

Part Overview

The FKDFZDK 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 functional replacement in applications where port count and connector generation compatibility are maintained.

Substitute Part Grouping Explanation

Substitute parts for the FKDFZDK are identified based on strict parameter equivalence across electrical and mechanical specifications. The primary substitution criteria are:

Electrical Parameters: Impedance (50 Ohms), connector type (Jack, Female Socket), contact and shield termination method (Crimp), frequency capability (6 GHz maximum), and Fakra Code Z designation.

Mechanical Parameters: Mounting type (Free Hanging In-Line), fastening mechanism (Latch Lock), cable group compatibility (RG-174, 316), and housing color (Blue, Water).

Environmental & Compliance Parameters: Operating temperature range (-40°C to 105°C), mating cycle rating (25), RoHS3 compliance, and MSL rating (1 - Unlimited).

Port Configuration: The FKDFZDK features 2 ports. Substitute parts maintaining dual-port configuration (FKDFZG) are direct functional equivalents. Single-port variants (FK1FZDK, FK1FZG) represent alternative connector generations within the Fakra Code Z family and are listed as available substitutes where application architecture permits single-port implementation.

All substitute parts are manufactured by Taoglas Limited, maintain Active product status, and share identical compliance certifications (ROHS3, REACH Unaffected, EAR99).

Engineering Selection Recommendations

Direct Dual-Port Equivalent: FKDFZG is the primary substitute for FKDFZDK. Both parts maintain identical port count (2), connector generation, and all electrical and mechanical specifications. Selection between FKDFZDK and FKDFZG is based on inventory availability and application-specific requirements, as both are Active products with ROHS3 compliance and equivalent performance characteristics.

Single-Port Alternatives: FK1FZDK and FK1FZG represent single-port Fakra Code Z connectors from the first-generation Fakra family. These parts are substitutes where application architecture has been modified to accommodate single-port connector configurations. All electrical parameters (50-ohm impedance, 6 GHz frequency capability, crimp termination) and environmental ratings remain equivalent to the dual-port main part.

Compliance Basis: All parts listed maintain ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification. MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling. All parts are manufactured by Taoglas Limited and carry Active product status, ensuring continued availability and support.

Port Configuration Consideration: Selection of single-port variants (FK1FZDK, FK1FZG) requires confirmation that application design supports single-port implementation. Dual-port variants (FKDFZDK, FKDFZG) are required for applications specifying dual-port connector architecture.

Frequently Asked Questions (FAQ)

Q: Can FK1FZDK or FK1FZG be used as direct replacements for FKDFZDK?

A: FK1FZDK and FK1FZG are single-port connectors, while FKDFZDK is a dual-port connector. These parts are substitutes only when application design permits single-port implementation. Electrical parameters are equivalent; port count differs.

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

A: FKDFZDK and FKDFZG are functionally equivalent dual-port SMB Fakra Code Z connectors with identical electrical and mechanical specifications. Both maintain 50-ohm impedance, 6 GHz frequency capability, crimp termination, and -40°C to 105°C operating range. Selection is based on inventory availability and application requirements.

Q: Are FK1FZDK and FK1FZG interchangeable with each other?

A: FK1FZDK and FK1FZG are both single-port Fakra Code Z connectors with equivalent electrical and mechanical parameters. Both maintain 50-ohm impedance, 6 GHz frequency capability, and identical termination methods. Selection between these parts is based on inventory availability.

Q: Do all substitute parts support the same cable groups?

A: Yes. All listed parts (FKDFZDK, FKDFZG, FK1FZDK, FK1FZG) support RG-174 and RG-316 cable groups with crimp termination for both contact and shield.

Q: What is the operating temperature range for all substitute parts?

A: All parts operate across -40°C to 105°C. This range is consistent across FKDFZDK, FKDFZG, FK1FZDK, and FK1FZG.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. FKDFZDK, FKDFZG, FK1FZDK, and FK1FZG are all ROHS3 compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints.

Q: What is the mating cycle rating for these connectors?

A: All listed parts maintain a mating cycle rating of 25, indicating the connector is rated for 25 mating and unmating cycles.

Q: Can these connectors be used in applications requiring frequencies above 6 GHz?

A: No. All listed parts are rated to a maximum frequency of 6 GHz. Applications requiring higher frequency capability require alternative connector families.

Q: What fastening mechanism do these connectors use?

A: All listed parts use Latch Lock fastening, providing secure mating and unmating with mechanical locking engagement.

Q: Are there any differences in housing color between substitute parts?

A: No. All listed parts feature Blue and Water housing color designation, maintaining visual consistency across the substitution group.
