C201305A-202

Overview

The ITG Electronics C201305A-202 is a miniature coaxial switch designed for RF signal routing. It features a single-pole double-throw (SPDT) configuration with a common port and two selectable output paths. The device utilizes a hermetically sealed metal housing to ensure reliable operation in demanding environments. Electrical specifications include a frequency range extending up to 4 GHz, with typical insertion loss under 0.5 dB and isolation greater than 60 dB at DC. The switch operates via a manual toggle mechanism, providing clear visual position indication. It supports a maximum operating voltage of 500 VDC and handles continuous power levels suitable for standard test and measurement applications.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm mechanical interface dimensions and contact material options. Ensure that the required voltage rating and power handling capabilities align with the system design parameters before procurement. Confirm hermetic sealing requirements if the application involves harsh environmental conditions or vacuum compatibility. Cross-reference the pinout configuration with the system schematic to prevent wiring errors during installation.

Selection Notes

Select this component based on its SPDT topology and frequency coverage up to 4 GHz. Evaluate the physical size constraints against the available mounting space in the enclosure. Consider the manual actuation method versus automated alternatives if remote control is required. Assess the thermal management needs relative to the expected continuous power dissipation. Verify compatibility with existing connector types and cable assemblies for seamless integration into the RF chain.

Part Context

This model belongs to ITG Electronics' line of miniature coaxial switches, which are engineered for high-reliability applications. The series typically offers various pole configurations and actuation methods to suit different system requirements. These switches are commonly used in scenarios requiring precise signal path control with minimal signal degradation. The brand emphasizes durability and consistent electrical performance across temperature variations, making them suitable for industrial and military-grade deployments.

Replacement Considerations

Consult the manufacturer's cross-reference guide for direct equivalent part numbers. Verify that any substitute component matches the critical electrical parameters, including frequency range, insertion loss, and isolation levels. Ensure mechanical footprint and mounting hole patterns are compatible with existing PCB layouts or chassis cutouts. Confirm that the replacement maintains the same hermetic sealing standards if environmental resistance is required.
