Substitute Part Grouping Explanation

The substitute part 01002-7811 qualifies as a direct equivalent based on the following critical parameters that determine functional interchangeability:

• Encoder Type: Both parts utilize optical encoding technology
• Output Type: Both provide quadrature output with index signal (incremental)
• Pulses per Revolution: Both deliver 2500 PPR resolution
• Voltage Supply Range: Both operate across 5V to 28V
• Actuator Type: Both feature shaft-type actuators
• Mounting Configuration: Both use chassis mount orientation with user-selectable mounting
• Termination: Both employ connector-based termination
• Rotational Life: Both specify 200M cycle minimum rating
• Regulatory Classification: Both carry EAR99 ECCN and 8543.70.4500 HTSUS codes

The primary distinction is product status: 01002-3910 is obsolete while 01002-7811 is active, with the latter belonging to the XH25 series versus the H25 series of the original part.

Parameter Comparison
