Key Parameters

Substitute Part Grouping Explanation

Substitution of the Crouzet 84145020 is based on the following critical parameters that define functional equivalence:

• Output Configuration: AC output capability at 24~250VAC range
• Output Current Rating: Minimum 500mA capacity
• Input Supply: 5VDC or compatible low-voltage DC input (3~12VDC range acceptable)
• Mounting Interface: DIN Rail mount form factor
• Switching Characteristics: Comparable turn-on and turn-off response times
• Environmental Compliance: RoHS and REACH compliance status
• Reliability Classification: MSL 1 rating for unlimited moisture exposure

The Sensata-Crydom DRA-CN240A05 solid-state relay module meets these substitution criteria through its AC output switching capability, compatible input voltage range, DIN Rail mounting, and equivalent environmental compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Sensata-Crydom DRA-CN240A05 serves as the primary substitute for the obsolete Crouzet 84145020 based on the following engineering criteria:

Compliance & Regulatory: Both components maintain equivalent environmental compliance with RoHS and REACH standards. The DRA-CN240A05 achieves ROHS3 compliance, representing current regulatory alignment superior to the legacy RoHS Compliant designation of the original module.

Functional Compatibility: The DRA-CN240A05 provides AC output switching across the identical 24~250V load voltage range. The input voltage specification of 3~12VDC encompasses the 5VDC requirement of the original design, ensuring direct compatibility with existing control circuits.

Current Rating Consideration: The DRA-CN240A05 provides 2A output capacity, exceeding the 500mA specification of the Crouzet 84145020. This increased current rating provides design margin and supports applications requiring higher switching capacity within the same form factor.

Reliability & Availability: The DRA-CN240A05 maintains active product status with documented inventory availability, addressing the obsolescence constraint of the original component. Both components share MSL 1 classification, confirming equivalent moisture tolerance for industrial environments.

Frequently Asked Questions (FAQ)

Q: Can the Sensata-Crydom DRA-CN240A05 directly replace the Crouzet 84145020 in existing installations?

A: Yes, the DRA-CN240A05 provides functional equivalence for AC output switching applications. Both components support identical load voltage ranges (24~250VAC), DIN Rail mounting, and environmental compliance requirements. The substitute's 5VDC input falls within the specified 3~12VDC input range, ensuring compatibility with existing control signal sources.

Q: What is the significance of the higher 2A current rating on the DRA-CN240A05 compared to the 500mA specification of the original module?

A: The increased current capacity of the DRA-CN240A05 provides design margin and supports applications requiring higher AC load switching capacity. This enhancement does not compromise compatibility; it expands the operational envelope for load switching applications within the same physical form factor.

Q: Are there packaging or termination differences between these components?

A: The Crouzet 84145020 specifies DIN Rail Mount style without detailed termination information. The Sensata-Crydom DRA-CN240A05 utilizes Screw Terminal termination within a Module package format, both compatible with standard DIN Rail mounting infrastructure. Verify terminal compatibility with existing wiring harnesses during integration.

Q: How do the switching response times compare between these modules?

A: The Crouzet 84145020 specifies 10ms turn-on and turn-off times. The Sensata-Crydom DRA-CN240A05 includes zero-cross switching capability, which optimizes AC load switching by synchronizing with AC waveform zero-crossing points. Detailed switching time specifications for the DRA-CN240A05 should be verified against application timing requirements.

Q: What compliance advantages does the DRA-CN240A05 provide over the original Crouzet module?

A: The DRA-CN240A05 achieves ROHS3 compliance, representing current regulatory alignment with the latest RoHS directive requirements. Both components maintain REACH Unaffected status and MSL 1 moisture sensitivity classification, confirming equivalent environmental reliability for industrial control applications.
