Key Parameters

Substitute Part Grouping Explanation

The AS33-M50M-S74 can be substituted with the AS33-M42M-S74 based on the following critical parameters that remain consistent across both components:

Matching Parameters:

• Encoder Type: Magnetic
• Output Type: SSI
• Voltage Supply Range: 7V ~ 12.5V
• Actuator Type: External Magnet, Not Included
• Mounting Type: Chassis Mount, Motors
• Orientation: Vertical
• Termination Style: Connector
• Detent: No
• Built in Switch: No
• RoHS Status: ROHS3 Compliant
• Manufacturer: Broadcom Limited

The primary difference between these components is the pulses per revolution specification, where the AS33-M42M-S74 offers programmable pulses per revolution capability, providing enhanced flexibility for system integration compared to the fixed specification of the obsolete AS33-M50M-S74.

Parameter Comparison

Engineering Selection Recommendations

The AS33-M42M-S74 is the appropriate substitute for the obsolete AS33-M50M-S74. This recommendation is based on the following engineering criteria:

Product Status: The AS33-M42M-S74 maintains active product status with Broadcom Limited, ensuring ongoing availability, technical support, and supply chain continuity. The AS33-M50M-S74 is classified as obsolete and no longer supported.

Regulatory Compliance: Both components maintain ROHS3 compliance, satisfying environmental and regulatory requirements for electronic component manufacturing and deployment.

Functional Equivalence: The substitute part preserves all critical electrical and mechanical parameters including magnetic encoder type, SSI output interface, identical supply voltage range, external magnet actuator configuration, chassis mount capability, vertical orientation, and connector termination.

Enhanced Capability: The AS33-M42M-S74 provides programmable pulses per revolution functionality, offering system designers greater flexibility in configuration compared to the fixed specification of the original part.

Frequently Asked Questions (FAQ)

Q: Can the AS33-M42M-S74 directly replace the AS33-M50M-S74 in existing applications?

A: Yes. Both components share identical electrical specifications (7V ~ 12.5V supply, SSI output), mechanical mounting characteristics (chassis mount, vertical orientation), and connector termination. The substitute part is functionally compatible with systems designed for the original component.

Q: What is the primary difference between these two encoder modules?

A: The AS33-M42M-S74 features programmable pulses per revolution, whereas the AS33-M50M-S74 operates with a fixed pulses per revolution specification. This enhancement provides greater configuration flexibility for system integration.

Q: Why is the AS33-M50M-S74 classified as obsolete?

A: Broadcom Limited has discontinued this product line. The AS33-M42M-S74 represents the active equivalent within the AS33 magnetic encoder family and is the recommended replacement for new designs and field replacements.

Q: Are there packaging differences between these components?

A: The AS33-M42M-S74 is supplied in tray packaging. Packaging specifications for the AS33-M50M-S74 are not documented. Verify packaging requirements for your procurement and assembly processes.

Q: Do both components require external magnets?

A: Yes. Both the AS33-M50M-S74 and AS33-M42M-S74 utilize external magnet actuators that are not included with the component. External magnets must be sourced separately and integrated into the application assembly.

Q: Are there any compliance certifications that differ between these parts?

A: Both components maintain ROHS3 compliance. The AS33-M42M-S74 carries EAR99 ECCN classification and HTSUS code 8543.70.4500 for export and tariff purposes.
