DC60SA7-B Equivalent & Substitute Parts

Part Overview

The DC60SA7-B is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NC (1 Form B) device in a hockey puck package. This component is designed for DC load switching applications with a rated load current of 7A and load voltage range of 3V to 60V. The part is currently obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DC60SA7-B is based on the following critical parameters that must remain consistent:

• Circuit Configuration: SPST-NC (1 Form B) topology
• Load Current Rating: 7 A minimum
• Load Voltage Range: 3 V – 60 V compatibility
• Output Type: DC switching capability
• Package Type: Hockey Puck form factor
• Mounting Type: Chassis Mount
• Termination Style: Screw Terminal

The DC60S7-B qualifies as a direct substitute because it maintains identical electrical specifications for load switching (7A, 3V–60V DC), circuit configuration (SPST-NC), package form factor (hockey puck), and termination method (screw terminal). The primary difference is the input voltage specification, which reflects a design variant within the same product series.

Parameter Comparison

Engineering Selection Recommendations

The DC60S7-B is the manufacturer-recommended substitute for the obsolete DC60SA7-B. Both components are manufactured by Sensata-Crydom within the same DC60 series and maintain identical load switching specifications (7A, 3V–60V DC output).

The DC60S7-B is currently in active production status, ensuring availability for new procurement and system maintenance. The component carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. Both parts share identical mechanical packaging (hockey puck chassis mount with screw terminals), enabling direct physical replacement in existing designs.

The input voltage specification differs between the two variants: the DC60SA7-B accepts 90–280 VAC input, while the DC60S7-B accepts 4.6–32 VDC input. Selection between these variants depends on the control signal voltage available in the target application.

Frequently Asked Questions (FAQ)

Q: Can the DC60S7-B directly replace the DC60SA7-B in all applications?

A: The DC60S7-B is mechanically and electrically compatible for load switching functions. However, the input voltage specification differs: DC60SA7-B requires 90–280 VAC control input, while DC60S7-B requires 4.6–32 VDC control input. Substitution is valid only when the available control signal matches the DC60S7-B input voltage range.

Q: What are the critical parameters for substitution?

A: Load current (7A), load voltage range (3V–60V DC), circuit configuration (SPST-NC), and package type (hockey puck) must remain constant. The input voltage specification is application-dependent and must be verified against the control signal available in the target circuit.

Q: Is the DC60S7-B available in the same packaging as the DC60SA7-B?

A: Yes. Both components use the hockey puck package form factor with chassis mount configuration and screw terminal termination, enabling direct physical replacement.

Q: What compliance certifications apply to the substitute part?

A: The DC60S7-B carries ROHS3 compliance certification and maintains REACH Unaffected status, consistent with current regulatory requirements for electronic components.

Q: Why is the DC60SA7-B obsolete?

A: The DC60SA7-B has been discontinued by the manufacturer. The DC60S7-B represents the active production alternative within the same product series.
