Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS33-M50M-K54 is determined by strict alignment of the following critical parameters:

• Encoder type: Magnetic
• Output interface: RS-485
• Supply voltage range: 4.5V ~ 5.5V
• Mounting configuration: Chassis Mount, Motors
• Orientation: Vertical
• Termination method: Connector
• Actuator type: External Magnet, Not Included
• RoHS compliance: ROHS3 Compliant

The AS33-M42M-K54 satisfies all substitution criteria. Both components share identical electrical specifications, mechanical mounting requirements, and regulatory compliance status. The primary distinction lies in the pulses per revolution specification, where the AS33-M42M-K54 offers programmable pulse configuration compared to the fixed specification of the original part.

Parameter Comparison

Engineering Selection Recommendations

The AS33-M42M-K54 is the qualified substitute for the obsolete AS33-M50M-K54. Selection of this alternative component is supported by:

• Active product status ensuring ongoing availability and supply chain continuity
• Full compliance with ROHS3 regulatory requirements
• Identical electrical and mechanical interface specifications
• Equivalent RS-485 communication protocol implementation
• Matching supply voltage operating range and connector termination architecture

The transition from the fixed-specification AS33-M50M-K54 to the programmable AS33-M42M-K54 provides enhanced configuration flexibility without compromising system compatibility.
