FKDFIDK Equivalent & Substitute Parts

Part Overview

The FKDFIDK is a dual-port SMB Fakra Code I 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 ROHS3 compliant and currently active in production with 1021 units in stock. Substitute parts are identified for applications requiring single-port configurations or alternative connector variants while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FKDFIDK are identified based on strict electrical and mechanical parameter matching within the Taoglas Limited Fakra connector family. The substitution logic is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Impedance: 50 Ohms (all substitutes match)
• Frequency - Max: 6 GHz (all substitutes match)
• Connector Style: SMB, Fakra (all substitutes match)
• Features: Code I (all substitutes match)

Mechanical Compatibility Parameters:

• Connector Type: Jack, Female Socket (all substitutes match)
• Contact Termination: Crimp (all substitutes match)
• Shield Termination: Crimp (all substitutes match)
• Mounting Type: Free Hanging (In-Line) (all substitutes match)
• Cable Group: RG-174, 316 (all substitutes match)
• Fastening Type: Latch Lock (all substitutes match)

Environmental & Compliance Parameters:

• Operating Temperature: -40°C ~ 105°C (all substitutes match)
• Mating Cycles: 25 (all substitutes match)
• RoHS Status: ROHS3 Compliant (all substitutes match)
• REACH Status: REACH Unaffected (all substitutes match)

Port Configuration Variation: The FKDFIDK features 2 ports, while FK1FIDK and FK1FIG feature 1 port each. FKDFIG maintains the 2-port configuration. Port count variation does not affect electrical or mechanical substitution eligibility when application requirements permit single-port or dual-port configurations.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—FK1FIDK, FK1FIG, and FKDFIG—are manufactured by Taoglas Limited and maintain full electrical and mechanical compatibility with the FKDFIDK across all specified parameters. All parts are ROHS3 compliant, REACH unaffected, and carry active product status.

For dual-port applications: FKDFIG provides direct functional equivalence to FKDFIDK with identical port configuration and all electrical/mechanical specifications. FKDFIG currently has the highest inventory availability at 1136 units.

For single-port applications: FK1FIDK and FK1FIG are functionally equivalent single-port variants. Both maintain identical electrical performance, impedance, frequency response, and environmental ratings. FK1FIDK inventory is 977 units; FK1FIG inventory is 938 units.

Compliance and Environmental Considerations: All parts operate within the -40°C to 105°C temperature range with 25 mating cycles and MSL rating of 1 (unlimited moisture sensitivity). All parts support RG-174 and RG-316 cable groups with crimp termination for both contact and shield.

Frequently Asked Questions (FAQ)

Q: Can FK1FIDK or FK1FIG be used as direct replacements for FKDFIDK?

A: FK1FIDK and FK1FIG are single-port connectors, while FKDFIDK is a dual-port connector. Electrical and mechanical compatibility is maintained; however, application requirements must accommodate the single-port configuration. These parts are suitable for applications requiring only one RF connection point.

Q: What is the difference between FK1FIDK and FK1FIG?

A: Both FK1FIDK and FK1FIG are single-port SMB Fakra Code I female socket connectors with identical electrical and mechanical specifications. The primary difference is inventory availability: FK1FIDK has 977 units in stock, while FK1FIG has 938 units in stock.

Q: Is FKDFIG a complete equivalent to FKDFIDK?

A: FKDFIG is a parametric equivalent to FKDFIDK. Both are dual-port connectors with identical electrical specifications (50 ohms, 6 GHz maximum frequency), mechanical configuration (SMB Fakra Code I, crimp termination, free-hanging in-line mounting), and environmental ratings (-40°C to 105°C, 25 mating cycles). FKDFIG has higher inventory availability at 1136 units.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. FKDFIDK, FK1FIDK, FK1FIG, and FKDFIG are all ROHS3 compliant and REACH unaffected.

Q: What cable types are compatible with these connectors?

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

Q: Do all substitute parts have the same operating temperature range?

A: Yes. All parts operate across -40°C to 105°C with identical mating cycle ratings of 25 cycles and MSL rating of 1 (unlimited).

Q: What is the significance of the Fakra Code I designation?

A: Fakra Code I is a standardized connector code designation that ensures mechanical and electrical compatibility within the Fakra connector family. All listed parts share this Code I specification, confirming interchangeability within this connector class.
