Substitute Part Grouping Explanation

The SMSAP20AF03DCP is substituted by MC88CH2ORT1, also manufactured by Carlo Gavazzi Inc. The substitution is based on the following critical parameters that define functional equivalence in magnetic sensing applications:

• Magnetic Actuation Principle: Both devices utilize magnetic sensing technology with non-contact operation
• Output Configuration: Both provide normally open (NO) switching output for safety interlock circuits
• Supply Voltage Compatibility: The substitute operates at 12V ~ 24V, which encompasses the 50VDC supply voltage of the original part
• Operating Temperature Range: The substitute extends the upper temperature limit to 80°C, maintaining the lower limit of -25°C
• Ingress Protection: Both devices maintain sealed construction suitable for industrial environments
• Manufacturer Continuity: Both parts are from Carlo Gavazzi Inc., ensuring design philosophy and quality standards alignment
• Regulatory Compliance: Both components meet international safety standards

Parameter Comparison

Engineering Selection Recommendations

The MC88CH2ORT1 is the manufacturer-recommended substitute for the obsolete SMSAP20AF03DCP. Selection of this alternative is justified on the following engineering grounds:

• Product Lifecycle: The original SMSAP20AF03DCP is obsolete. The MC88CH2ORT1 is an active product with current manufacturing support and availability
• Functional Equivalence: Both devices employ magnetic sensing principles with non-contact actuation, suitable for safety interlock applications
• Voltage Compatibility: The substitute's 12V ~ 24V supply range accommodates the 50VDC requirement of the original specification
• Temperature Performance: The extended upper operating temperature of 80°C provides improved thermal margin compared to the original 70°C limit
• Manufacturer Support: Both components originate from Carlo Gavazzi Inc., ensuring consistent design standards and technical support continuity
• Regulatory Alignment: Both devices carry international safety certifications appropriate for industrial control applications

Frequently Asked Questions (FAQ)

Q: Can MC88CH2ORT1 directly replace SMSAP20AF03DCP in existing installations?

A: The MC88CH2ORT1 provides functional equivalence as a magnetic non-contact switch. However, physical mounting and connector compatibility must be verified. The original part uses M12 cable connector termination, while the substitute uses a flange mount connector configuration. Mechanical integration assessment is required before installation.

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

A: The SMSAP20AF03DCP is a DPST-NO interlock switch with dual pole configuration, while the MC88CH2ORT1 is a 2NO (dual normally open) magnetic sensor. Both provide non-contact magnetic switching but differ in circuit topology and mounting approach.

Q: Are the supply voltage specifications compatible?

A: The original part operates at 120VAC and 50VDC. The substitute operates at 12V ~ 24V DC. If the system uses 50VDC supply, the substitute is compatible. If the system uses 120VAC, a voltage conversion or alternative solution may be required.

Q: What is the operating distance specification for the substitute?

A: The must-operate and must-release distances for MC88CH2ORT1 are not specified in the available technical data. These parameters should be obtained from the manufacturer's detailed datasheet before final integration.

Q: Are both parts certified for the same regulatory standards?

A: The SMSAP20AF03DCP carries CE and UL certifications. The MC88CH2ORT1 certification status is not specified in the provided data. Verification of applicable certifications for your specific application is recommended through the manufacturer's documentation.

Q: What is the frequency rating of the substitute?

A: The MC88CH2ORT1 is rated for 100 Hz operation, indicating suitability for moderate-speed switching applications typical of safety interlock systems.
