D2D07 Solid State Relay SPST-NO Equivalent & Substitute Parts

Part Overview

The D2D07 is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a single-pole single-throw normally open (SPST-NO) device in a hockey puck form factor. This relay is designed for DC load switching applications with a rated load current of 7 A and load voltage range of 1 V to 200 V. The device is actively produced and maintains ROHS3 compliance. Substitute parts are identified when inventory constraints, performance requirements, or application-specific needs necessitate alternative component selection while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D2D07 are qualified based on the following critical parameters that determine functional interchangeability:

• Circuit configuration: SPST-NO (1 Form A) topology
• Output type: DC switching
• Input voltage range: Minimum 4.6 VDC control signal capability
• Load voltage range: Minimum 1 V to maximum 200 V load support
• Load current rating: Equal to or greater than 7 A
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Package form factor: Hockey Puck

The identified substitutes (84134850 and 84137650N) meet or exceed these core parameters. Both alternatives support the required load voltage range and provide equal or higher current ratings, ensuring functional compatibility in applications originally specified for the D2D07.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain active product status and comply with applicable environmental regulations. The 84134850 (Sensata-Crydom, GN DC series) is manufactured by the same supplier as the D2D07 and provides identical input voltage range with improved on-state resistance (210 mOhms versus 290 mOhms). This part supports the full load voltage range of 1 V to 200 V and carries ROHS3 compliance.

The 84137650N (Crouzet, GNAD series) offers equivalent current capacity (10 A) and maintains the hockey puck form factor with screw terminal connectivity. This part specifies a minimum load voltage of 5 V and minimum input voltage of 4 VDC. RoHS compliance is confirmed, though the specific revision level differs from the D2D07.

Selection between substitutes depends on application-specific load voltage requirements. Applications requiring load voltages below 5 V must use the D2D07 or 84134850. Applications with load voltages at or above 5 V may utilize any of the three parts.

Frequently Asked Questions (FAQ)

Q: Can the 84134850 directly replace the D2D07 in all applications?

A: Yes. The 84134850 maintains identical input voltage range (4.6 ~ 32 VDC), identical load voltage range (1 V ~ 200 V), and identical circuit configuration (SPST-NO). The higher current rating (10 A versus 7 A) and lower on-state resistance provide equivalent or improved performance. Screw terminal connectivity and hockey puck form factor are identical.

Q: What is the key difference between the 84137650N and the other two parts?

A: The 84137650N specifies a minimum load voltage of 5 V, whereas both the D2D07 and 84134850 support load voltages as low as 1 V. The 84137650N is manufactured by Crouzet rather than Sensata-Crydom. All three parts share identical circuit topology, mounting type, termination style, and package form factor.

Q: Are there input voltage compatibility concerns when substituting?

A: No. All three parts accept control input signals in the 4.6 ~ 32 VDC range (84137650N minimum 4 VDC). Standard control circuits designed for the D2D07 will operate the substitute parts without modification.

Q: Does the hockey puck form factor remain consistent across all three parts?

A: Yes. All three parts use the hockey puck package with screw terminal connections, ensuring mechanical and electrical compatibility in existing mounting configurations.

Q: Which substitute should be selected for applications with load voltages below 5 V?

A: The 84134850 is the appropriate selection for applications requiring load voltages below 5 V. The 84137650N specifies a 5 V minimum load voltage and is not suitable for such applications.
