DR06D12 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The DR06D12 is a Solid State SPST-NO (1 Form A) relay module manufactured by Sensata-Crydom, designed for DC switching applications. This active product operates with input voltage ranging from 4 to 32VDC and supports load voltages from 1V to 60V at 12A capacity. The module features DIN Rail mounting with screw terminal connections and maintains an on-state resistance of 100 mOhms maximum. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application compatibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DR06D12 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching functionality
• Output Type: Must be DC to ensure compatibility with the load circuit
• Mounting Interface: DIN Rail mounting is required for mechanical compatibility
• Termination Method: Screw terminal connections must be present for installation compatibility
• Load Current Capacity: The substitute must support the required 12A load current or higher
• Load Voltage Range: The substitute must accommodate the operating voltage window of 1V to 60V
• Input Voltage Compatibility: The substitute input voltage range must overlap with or encompass the 4 ~ 32VDC requirement
• Compliance Standards: RoHS3 compliance and REACH unaffected status ensure regulatory alignment

The ASR-SMD48D3P-K does not meet the substitution criteria for the DR06D12 due to insufficient load current capacity (3A versus 12A required) and reduced load voltage range (3V ~ 58V versus 1V ~ 60V).

Parameter Comparison

Engineering Selection Recommendations

Based on the provided specifications and compliance data, the ASR-SMD48D3P-K cannot serve as a direct substitute for the DR06D12 in applications requiring 12A load current capacity. The ASR-SMD48D3P-K is rated for 3A maximum load current, which represents a 75% reduction in switching capacity compared to the DR06D12.

Both components maintain active product status and ROHS3 compliance, ensuring regulatory alignment. However, the load current limitation of the ASR-SMD48D3P-K makes it unsuitable for circuits designed around the DR06D12's 12A specification.

For applications with reduced current requirements (3A or less), the ASR-SMD48D3P-K offers superior on-state resistance performance (37 mOhms versus 100 mOhms), resulting in lower power dissipation. The fixed 12VDC input voltage of the ASR-SMD48D3P-K may also present constraints in systems requiring the broader 4 ~ 32VDC input range of the DR06D12.

Frequently Asked Questions (FAQ)

Q: Can the ASR-SMD48D3P-K replace the DR06D12 in my application?

A: No. The ASR-SMD48D3P-K has a maximum load current rating of 3A, while the DR06D12 is rated for 12A. Direct substitution is not possible for applications requiring the full 12A capacity of the DR06D12.

Q: What are the critical differences between these two relay modules?

A: The primary differences are load current capacity (12A versus 3A), load voltage range (1V ~ 60V versus 3V ~ 58V), and input voltage flexibility (4 ~ 32VDC versus fixed 12VDC). Both share identical circuit configuration, mounting type, and termination style.

Q: Are both components RoHS compliant?

A: Yes. Both the DR06D12 and ASR-SMD48D3P-K are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Does the ASR-SMD48D3P-K have any performance advantages?

A: The ASR-SMD48D3P-K exhibits lower on-state resistance (37 mOhms versus 100 mOhms), resulting in reduced power dissipation during switching. This advantage applies only to applications within its 3A current rating.

Q: What mounting and termination options are available?

A: Both components feature DIN Rail mounting and screw terminal connections, ensuring mechanical and electrical compatibility with standard industrial control panel installations.

Q: Can I use the ASR-SMD48D3P-K in a lower-current version of my circuit?

A: The ASR-SMD48D3P-K is suitable only for applications requiring 3A or less load current. If your circuit can be redesigned to operate within this current limit, the component may be considered for that specific application variant.
