Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS33-M50M-K73 is determined by the following critical parameters:

• Encoder Type: Magnetic (required match)
• Output Type: RS-485 (required match)
• Voltage Supply Range: 7V ~ 12.5V (required match)
• Mounting Type: Chassis Mount, Motors (required match)
• Orientation: Vertical (required match)
• Termination Style: Connector (required match)
• Actuator Type: External Magnet, Not Included (required match)
• Form Factor: 33mm module diameter (required match)

The AS33-M42M-K73 meets all substitution criteria. While it operates with programmable pulses per revolution compared to the fixed 50B specification of the original part, this parameter does not restrict substitution eligibility as it represents a functional enhancement rather than a compatibility constraint.

Parameter Comparison

Engineering Selection Recommendations

The AS33-M42M-K73 is the designated substitute for the obsolete AS33-M50M-K73. Both components maintain identical electrical and mechanical specifications across all critical parameters: magnetic encoder type, RS-485 output protocol, 7V to 12.5V supply voltage, vertical orientation, connector termination, and external magnet actuation.

The AS33-M42M-K73 offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance, satisfying regulatory requirements. The programmable pulses per revolution feature of the substitute provides operational flexibility compared to the fixed 50B configuration of the original part.

Frequently Asked Questions (FAQ)

Q: Can the AS33-M42M-K73 directly replace the AS33-M50M-K73 in existing applications?

A: Yes. Both components share identical electrical and mechanical interfaces: RS-485 output, 7V to 12.5V supply voltage, vertical orientation, connector termination, and chassis mount configuration. The substitute maintains full compatibility with existing system designs.

Q: What is the difference between the fixed 50B pulses per revolution and the programmable configuration?

A: The AS33-M50M-K73 operates with a fixed 50B pulse count per revolution. The AS33-M42M-K73 provides programmable pulse configuration, allowing adjustment to system requirements without component substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both the AS33-M50M-K73 and AS33-M42M-K73 are ROHS3 compliant, meeting environmental and regulatory standards.

Q: What is the packaging difference between these components?

A: The AS33-M50M-K73 packaging specification is not provided in the technical data. The AS33-M42M-K73 is supplied in tray packaging.

Q: Why is the AS33-M50M-K73 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The AS33-M42M-K73 remains in active production and serves as the current equivalent for new designs and replacement applications.
