FKDFDG Equivalent & Substitute Parts

Part Overview

The FKDFDG is a dual-port SMB Fakra Code D coaxial connector manufactured by Taoglas Limited, designed for RF applications requiring 50-ohm impedance. This connector features a female socket jack configuration with crimp termination for both contact and shield, suitable for free-hanging in-line cable applications. The part is classified as Active with full ROHS3 compliance and REACH unaffected status. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory management, or component availability across manufacturing batches.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FKDFDG are determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Connector Style: SMB, Fakra
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency - Max: 6 GHz
• Contact Termination: Crimp
• Shield Termination: Crimp
• Cable Group: RG-174, 316

Mechanical Equivalence Criteria:

• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Latch Lock
• Operating Temperature: -40°C ~ 105°C
• Mating Cycles: 25
• Housing Color: Violet, Bordeaux

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The primary distinction among substitute parts is the Number of Ports: the FKDFDG features 2 ports (dual configuration), while FK1FDG and FK1FDDK feature 1 port each. FKDFDDK maintains the 2-port configuration identical to the main part. All substitute parts share identical electrical performance, environmental ratings, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical equivalence to the FKDFDG within the specified parameter set. Selection between substitute options is determined by application-specific port requirements:

FKDFDDK is the direct functional equivalent to FKDFDG, maintaining the dual-port (2-port) configuration. This part is selected when the application requires two independent RF connections within a single connector assembly.

FK1FDG and FK1FDDK are single-port (1-port) variants that provide identical electrical performance and environmental ratings. These parts are selected for applications requiring only one RF connection, or when dual single-port connectors are preferred over a dual-port assembly.

All parts carry Active product status, ROHS3 compliance, and REACH unaffected designation, confirming regulatory alignment for current manufacturing and deployment. Moisture Sensitivity Level 1 (Unlimited) indicates no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can FK1FDG or FK1FDDK be used as direct replacements for FKDFDG?

A: FK1FDG and FK1FDDK are electrically and mechanically equivalent to FKDFDG across all RF performance parameters, impedance, frequency response, and environmental ratings. The primary difference is port count: FK1FDG and FK1FDDK feature 1 port, while FKDFDG features 2 ports. Selection depends on whether your application requires dual connections within a single connector or single connections.

Q: What is the difference between FKDFDDK and FKDFDG?

A: FKDFDDK and FKDFDG are functionally identical dual-port connectors with matching electrical specifications, impedance, frequency range, and environmental performance. Both maintain 2-port configuration and are suitable for applications requiring dual RF connections. Differences exist only in manufacturing batch designation and current inventory levels.

Q: Are FK1FDG and FK1FDDK interchangeable with each other?

A: FK1FDG and FK1FDDK are electrically and mechanically equivalent single-port variants. Both provide identical RF performance, impedance, frequency response, and environmental ratings. Selection between these parts is based on inventory availability and manufacturing batch requirements.

Q: What cable types are compatible with these connectors?

A: All substitute parts support RG-174 and RG-316 cable groups with crimp termination for both contact and shield connections.

Q: Do these connectors require special handling during storage or assembly?

A: No. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage, handling, or assembly processes.

Q: What is the maximum operating frequency for these connectors?

A: All parts are rated to 6 GHz maximum frequency, suitable for automotive antenna, telematics, and general RF applications within this frequency band.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. FKDFDG, FK1FDDK, FK1FDG, and FKDFDDK all carry ROHS3 compliance certification and REACH unaffected status, confirming regulatory alignment for current manufacturing standards.

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

A: All parts are rated for 25 mating cycles, defining the expected number of connection and disconnection operations over the connector lifetime.
