FK1FKG Equivalent & Substitute Parts

Part Overview

The FK1FKG is an SMB Fakra Connector Jack, Female Socket manufactured by Taoglas Limited, designed for 50 Ohm coaxial RF applications. This connector operates at frequencies up to 6 GHz and is configured for free hanging (in-line) crimp termination with RG-174 and RG-316 cable groups. The part is classified as Active product status with full ROHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component procurement, inventory management, or design flexibility.

Frequently Asked Questions (FAQ)

Q: Are FK1FKG and FK1FKDK electrically interchangeable?

A: Yes. Both parts are rated for 50 Ohm impedance, 6 GHz maximum frequency, and identical crimp termination specifications. They perform identically in RF signal transmission applications.

Q: Can these connectors be used with different cable types?

A: Both connectors are specified for RG-174 and RG-316 cable groups only. Use only these cable types for proper impedance matching and connector performance.

Q: What is the difference between FK1FKG and FK1FKDK?

A: The parts are parametrically equivalent. Both share the same base product number FK1FK and identical electrical and mechanical characteristics. Differences exist only in part number designation and current inventory levels.

Q: Are these connectors suitable for high-frequency applications?

A: These connectors operate up to 6 GHz maximum frequency. Applications requiring higher frequency performance require alternative connector designs.

Q: What is the mating cycle rating?

A: Both connectors are rated for 25 mating cycles. This specification defines the expected number of connection and disconnection operations before performance degradation.

Q: Are these parts RoHS compliant?

A: Yes. Both FK1FKG and FK1FKDK are ROHS3 compliant and REACH unaffected, meeting all current environmental and regulatory standards.

Q: What is the operating temperature range?

A: Both connectors operate from -40°C to 105°C. This range covers automotive, industrial, and consumer application environments.

Q: What does "Code K" feature indicate?

A: Code K is a Fakra connector designation indicating a specific connector configuration within the Fakra standard. Both parts share this identical feature specification.

Q: Can these connectors be used in free hanging or panel-mounted configurations?

A: These connectors are specified for free hanging (in-line) mounting only. They are not designed for panel-mount applications.

Q: What is the moisture sensitivity level?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or deployment.
