Key Parameters

Substitute Part Grouping Explanation

Substitution of the AS33-M50M-B74 is determined by strict equivalence across the following critical parameters:

• Encoder Technology: Magnetic encoding maintains sensor principle compatibility
• Output Protocol: BiSS-C digital interface ensures communication protocol compatibility
• Supply Voltage Range: 7V ~ 12.5V operational window must be maintained
• Mechanical Interface: Chassis mount orientation and vertical mounting configuration
• Connector Termination: Connector-based termination style for circuit integration
• External Magnet Actuation: Requirement for external magnet, not included with unit
• Environmental Compliance: ROHS3 compliance for regulatory alignment

The AS33-M42M-B74 satisfies all substitution criteria as an active product within the same AS33 magnetic encoder family, maintaining identical electrical specifications and mechanical mounting characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AS33-M42M-B74 is the direct substitute for the obsolete AS33-M50M-B74. Both components maintain identical electrical operating parameters, mechanical mounting specifications, and regulatory compliance certifications. The AS33-M42M-B74 is currently in active production status with confirmed inventory availability, ensuring supply chain continuity for replacement and new design applications.

The transition from AS33-M50M-B74 to AS33-M42M-B74 requires no circuit redesign, as the BiSS-C protocol, supply voltage range, connector termination, and mounting interface remain unchanged. The programmable pulses per revolution feature in the AS33-M42M-B74 provides additional configuration flexibility compared to the obsolete variant.

Frequently Asked Questions (FAQ)

Q: Can the AS33-M42M-B74 directly replace the AS33-M50M-B74 in existing designs?

A: Yes. Both components share identical electrical specifications (7V ~ 12.5V supply, BiSS-C output), mechanical mounting (vertical chassis mount), and connector termination. No circuit modifications are required.

Q: What is the primary difference between these two models?

A: The AS33-M42M-B74 features programmable pulses per revolution, whereas the AS33-M50M-B74 specification does not indicate this parameter. Both maintain the same physical form factor and electrical interface.

Q: Are there packaging differences between the obsolete and active parts?

A: The AS33-M42M-B74 is supplied in tray packaging. Packaging specifications for the AS33-M50M-B74 are not provided in the technical data.

Q: Does the AS33-M42M-B74 require external magnet actuation like the original part?

A: Yes. Both the AS33-M50M-B74 and AS33-M42M-B74 require external magnet actuation and do not include the magnet as part of the component package.

Q: What is the regulatory compliance status of the substitute part?

A: The AS33-M42M-B74 is ROHS3 compliant and classified under ECCN EAR99, meeting the same environmental standards as the obsolete AS33-M50M-B74.
