FK1FDG FAKRA GEN 1 CODE D Coaxial Connector Equivalent & Substitute Parts

Part Overview

The FK1FDG is an SMB Fakra connector jack with female socket configuration manufactured by Taoglas Limited. This 50 Ohm coaxial connector is designed for free hanging in-line applications with crimp termination for both contact and shield. The part operates across a temperature range of -40°C to 105°C and supports frequencies up to 6 GHz, making it suitable for automotive and RF applications requiring Code D Fakra connectivity. The FK1FDG maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when inventory constraints, supply chain disruptions, or procurement requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FK1FDG are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

Electrical Parameters:

• Impedance: 50 Ohms
• Frequency - Max: 6 GHz
• Number of Ports: 1

Mechanical Parameters:

• Connector Style: SMB, Fakra
• Connector Type: Jack, Female Socket
• Contact Termination: Crimp
• Shield Termination: Crimp
• Mounting Type: Free Hanging (In-Line)
• Cable Group: RG-174, 316
• Fastening Type: Latch Lock
• Housing Color: Violet, Bordeaux
• Features: Code D

Environmental & Compliance Parameters:

• Operating Temperature: -40°C ~ 105°C
• Mating Cycles: 25
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The FK1FDDK meets all these criteria and is classified as a parametric equivalent substitute for the FK1FDG.

Parameter Comparison

Engineering Selection Recommendations

Both the FK1FDG and FK1FDDK are active products manufactured by Taoglas Limited with identical electrical, mechanical, and environmental specifications. Selection between these parts should be based on availability and procurement requirements.

FK1FDG is the primary part number with 975 units in current inventory stock.

FK1FDDK is the parametric equivalent substitute with 881 units in current inventory stock.

Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Both support unlimited moisture sensitivity rating and identical operating temperature ranges. The parts are interchangeable for all applications requiring SMB Fakra Code D female socket connectors with 50 Ohm impedance, crimp termination, and free hanging in-line mounting.

Frequently Asked Questions (FAQ)

Q: Can FK1FDDK be used as a direct replacement for FK1FDG?

A: Yes. The FK1FDDK is a parametric equivalent substitute with identical electrical specifications (50 Ohms, 6 GHz maximum frequency), mechanical configuration (SMB Fakra jack, female socket, crimp termination), mounting type (free hanging in-line), cable compatibility (RG-174, 316), and environmental ratings (-40°C to 105°C operating temperature, 25 mating cycles). Both parts are ROHS3 compliant with unlimited moisture sensitivity rating.

Q: Are there any differences in connector compatibility between FK1FDG and FK1FDDK?

A: No. Both parts feature identical Fakra Code D configuration with latch lock fastening, violet bordeaux housing color, and single port design. They are compatible with the same mating connectors and cable assemblies.

Q: What is the significance of the Code D designation?

A: Code D is a Fakra connector standard specification that defines the physical and electrical interface characteristics. Both FK1FDG and FK1FDDK implement Code D, ensuring compatibility with Code D mating connectors and maintaining the 50 Ohm impedance specification.

Q: Do both parts support the same cable types?

A: Yes. Both FK1FDG and FK1FDDK are specified for RG-174 and RG-316 cable groups with crimp termination for both contact and shield.

Q: What is the difference between these part numbers?

A: The FK1FDG and FK1FDDK are distinct manufacturer part numbers from Taoglas Limited that share identical specifications. The difference exists at the part number level only; both parts are functionally and mechanically equivalent for all application requirements.

Q: Are compliance certifications identical for both parts?

A: Yes. Both FK1FDG and FK1FDDK carry ROHS3 compliance, REACH unaffected status, EAR99 export classification, and HTSUS code 8536.69.4010. Both maintain MSL 1 (unlimited) moisture sensitivity rating.
