FK1FCG Equivalent & Substitute Parts

Part Overview

The FK1FCG 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 rated for -40°C to 105°C operating temperature with 25 mating cycles. The part is actively produced, ROHS3 compliant, and suitable for free hanging in-line crimp termination applications using RG-174 or RG-316 cable groups. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory requirements necessitate additional suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of coaxial RF connectors is determined by strict equivalence across electrical and mechanical parameters. The FK1FCG and its substitute FK1FCDK are grouped as parametric equivalents based on identical specifications across all critical selection criteria:

Electrical Parameters: Both parts maintain 50 Ohm impedance, 6 GHz maximum frequency, and identical contact/shield termination methods (crimp).

Mechanical Parameters: Both connectors feature identical SMB Fakra jack female socket configuration, free hanging in-line mounting, latch lock fastening, and compatibility with RG-174 and RG-316 cable groups.

Environmental & Compliance: Both parts operate across -40°C to 105°C, support 25 mating cycles, maintain ROHS3 compliance, and carry identical MSL rating of 1 (Unlimited).

Connector Identification: Both parts share Code C designation and blue housing color, ensuring proper mating interface compatibility.

Substitution is valid when the primary part becomes unavailable or when secondary sourcing is required for supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

Both FK1FCG and FK1FCDK are active production parts manufactured by Taoglas Limited with identical electrical, mechanical, and environmental specifications. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation.

Compliance Status: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for EU and international markets.

Production Status: Both connectors are actively produced, ensuring long-term availability and consistent quality standards.

Inventory Considerations: FK1FCG maintains 1192 pieces in stock, while FK1FCDK maintains 1061 pieces in stock. Selection may be influenced by required delivery timelines and quantity requirements.

Application Compatibility: Both parts are functionally interchangeable in all 50 Ohm RF coaxial applications operating at frequencies up to 6 GHz with RG-174 or RG-316 cable terminations.
