K-LC6 Equivalent & Substitute Parts Reference

Part Overview

The K-LC6 is a radar transceiver module manufactured by RFbeam Microwave GmbH, operating in the 24.05GHz to 24.25GHz frequency band. This module integrates a ceramic patch antenna and is designed for through-hole mounting in 8-DIP package configuration. The K-LC6 is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. Substitute parts must maintain compatibility across RF performance, electrical specifications, and mechanical form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the K-LC6 is determined by the following critical parameters:

Frequency compatibility within the 24.05GHz to 24.25GHz band is mandatory. The antenna type (integrated ceramic patch) and mounting configuration (through-hole, 8-DIP module) must remain unchanged to ensure mechanical and electrical integration with existing PCB layouts. Supply voltage ranges must overlap with the original specification to maintain compatibility with existing power distribution circuits. Operating temperature range must encompass or exceed the original specification to ensure reliable operation across the intended thermal environment. RoHS3 compliance and MSL rating must be maintained for regulatory and manufacturing process compatibility.

The K-LC6-RFB-00D qualifies as a direct substitute based on these parameters: identical frequency range, antenna type, mounting method, and package configuration; overlapping voltage supply range; extended operating temperature range; and equivalent RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The K-LC6-RFB-00D is the direct substitute for the obsolete K-LC6. Both parts maintain identical RF family classification (RADAR), frequency band operation, antenna integration, and mechanical form factor. The substitute part carries active product status with confirmed ROHS3 compliance and REACH unaffected designation, ensuring regulatory compliance and supply chain continuity.

Electrical parameter variations between the two parts require circuit-level evaluation. The K-LC6-RFB-00D exhibits a 2dBm reduction in output power and increased current consumption (35mA additional draw in both receive and transmit modes). Power supply circuits must accommodate the increased current demand. Systems with output power margin requirements should verify that the 2dBm reduction does not impact link budget or system performance specifications. The extended operating temperature range of the substitute part (to 85°C) provides enhanced thermal margin.

Both parts are classified as MSL 1 (unlimited moisture sensitivity), eliminating moisture-related handling constraints during assembly and storage.

Frequently Asked Questions (FAQ)

Q: Can the K-LC6-RFB-00D be used as a direct replacement in existing K-LC6 designs?

A: Yes, from a mechanical and RF frequency perspective. The 8-DIP through-hole package and ceramic patch antenna configuration are identical. However, the increased current consumption (35mA additional in both modes) requires verification that existing power supply circuits can deliver the higher current without exceeding voltage regulation limits. The 2dBm output power reduction must be evaluated against system link budget requirements.

Q: What are the key differences between K-LC6 and K-LC6-RFB-00D?

A: The primary differences are output power (18dBm vs. 16dBm), current consumption (50mA vs. 85mA in both modes), voltage supply range (4.75V-5.25V vs. 4.8V-5.2V), and operating temperature upper limit (80°C vs. 85°C). RF sensitivity, frequency band, antenna type, and package configuration remain identical.

Q: Why does the substitute part consume more current?

A: The K-LC6-RFB-00D represents an active product with updated internal design. Increased current consumption is a characteristic of this revision. Power supply design must account for this specification change.

Q: Are both parts RoHS compliant?

A: Yes. Both the K-LC6 and K-LC6-RFB-00D are ROHS3 compliant. The substitute part additionally carries REACH unaffected designation.

Q: What is the voltage supply overlap between these parts?

A: The K-LC6 operates from 4.75V to 5.25V, while the K-LC6-RFB-00D operates from 4.8V to 5.2V. The overlapping range is 4.8V to 5.2V. Designs operating at the extremes of the original specification (below 4.8V or above 5.2V) require circuit modification.

Q: Is the packaging different between these parts?

A: No. Both parts use 8-DIP module packaging with through-hole mounting. The K-LC6 is supplied in bulk packaging, while the K-LC6-RFB-00D is supplied in trays. PCB footprint and mounting method are identical.
