Robot part compatibility checklist

A replacement part must fit the complete system—not only the mounting space.

Mechanical

Compare dimensions, mounting pattern, shaft or flange, travel, load, torque, speed, backlash, weight and enclosure rating.

Electrical

Verify supply voltage, current, peak load, polarity, connector, pinout, grounding and protection requirements. Similar connectors can have different pin assignments.

Communication and software

Confirm protocol, network settings, controller support, firmware, drivers, licensing and calibration procedure.

Environment and safety

Check temperature, dust and water exposure, vibration, chemical resistance, duty cycle and certifications required by the final application.

Document the decision

Keep the datasheet, exact Part #, revision, seller statements and test results with the maintenance record. When uncertain, obtain confirmation from the manufacturer.
