Substitute parts for the 513360-8 are identified based on strict electrical and mechanical parameter matching within the Grayhill Series 51 rotary encoder family. The substitution criteria are:

Critical Matching Parameters:

• Encoder Type: Mechanical
• Output Type: BCD (Absolute)
• Pulses per Revolution: 8
• Actuator Type: 1/8" Dia Flatted End
• Detent: Yes
• Mounting Type: Panel, PCB Through Hole
• Orientation: Vertical
• Termination Style: PC Pin
• Rotational Life: 25K cycles minimum
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these parameters are classified as direct substitutes and can be used interchangeably in applications designed for the 513360-8.

Parameter Comparison

Engineering Selection Recommendations

The 513374-8 is a direct functional equivalent to the 513360-8 based on complete parameter alignment across all electrical and mechanical specifications. Both parts are active products from Grayhill Inc. Series 51, maintaining identical performance characteristics including 8 PPR BCD absolute output, mechanical encoding, vertical orientation, and PC pin termination.

Both components satisfy ROHS3 compliance requirements and REACH unaffected status, ensuring regulatory compatibility in applications subject to environmental and hazardous substance restrictions. The MSL 1 rating for both parts indicates unlimited moisture sensitivity, suitable for standard storage and handling conditions without special precautions.

Selection between these parts should be based on inventory availability, lead time requirements, and supply chain considerations, as all functional and compliance parameters are equivalent.

Frequently Asked Questions (FAQ)
