SSC800-25-24 Equivalent & Substitute Parts

Part Overview

The SSC800-25-24 is a solid-state relay (SSR) manufactured by Sensata-Crydom, designed for high-voltage DC switching applications. This chassis-mounted relay operates with a 24VDC control input and handles loads up to 800VDC at 25A continuous current. The part features a hockey puck package with screw terminal connections and SPST-NO (1 Form A) circuit configuration.

The SSC800-25-24 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and new designs.

Key Parameters

Substitute Part Grouping Explanation

The SSC1000-25-24 qualifies as a direct substitute for the SSC800-25-24 based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Manufacturer: Sensata-Crydom (same manufacturer, same product series SSC)
• Circuit Configuration: SPST-NO (1 Form A) — identical switching topology
• Output Type: DC — same load type
• Load Current: 25 A — identical current rating
• Voltage - Input: 20 ~ 28VDC — identical control voltage range
• Mounting Type: Chassis Mount — same mechanical installation method
• Termination Style: Screw Terminal — compatible connection interface
• Package / Case: Hockey Puck — identical form factor

Distinguishing Parameter:

• Voltage - Load: SSC1000-25-24 rated for 0 ~ 1000V (versus 0 ~ 800V for SSC800-25-24)

The SSC1000-25-24 provides enhanced voltage capability while maintaining full compatibility across all other functional and mechanical specifications. This substitution is valid for applications operating at or below 800VDC.

Parameter Comparison

Engineering Selection Recommendations

The SSC1000-25-24 is the appropriate substitute for the obsolete SSC800-25-24. Selection is based on the following factors:

Product Status: The SSC1000-25-24 carries Active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity. The SSC800-25-24 is obsolete and subject to discontinuation.

Compliance & Certifications: The SSC1000-25-24 is ROHS3 Compliant, meeting current environmental and regulatory requirements. Both parts maintain REACH Unaffected status and EAR99 export classification.

Electrical Compatibility: The SSC1000-25-24 maintains identical input voltage range (20 ~ 28VDC), load current (25A), and circuit configuration (SPST-NO). The increased load voltage rating (1000V versus 800V) provides additional design margin without compromising compatibility in applications operating at 800VDC or below.

Mechanical Compatibility: Identical mounting type (Chassis Mount), termination style (Screw Terminal), and package form factor (Hockey Puck) ensure direct physical and electrical integration without modification to existing installations or PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the SSC1000-25-24 directly replace the SSC800-25-24 in existing applications?

A: Yes. The SSC1000-25-24 maintains identical electrical specifications for input voltage, load current, and circuit configuration. The mechanical interface (screw terminals, hockey puck package, chassis mount) is identical. Direct substitution is valid for all applications operating at 800VDC or below.

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

A: The SSC1000-25-24 is rated for load voltages up to 1000VDC, compared to 800VDC for the SSC800-25-24. All other parameters are identical. This higher voltage rating provides additional design margin.

Q: Why is the SSC800-25-24 listed as obsolete?

A: The SSC800-25-24 has been discontinued by the manufacturer. The SSC1000-25-24 serves as the active replacement within the SSC series, offering equivalent functionality with enhanced voltage capability and current compliance certifications.

Q: Are there any package or termination differences?

A: No. Both parts use the hockey puck package form factor with screw terminal connections. Physical dimensions and mounting interfaces are identical, allowing direct board-level substitution.

Q: What compliance certifications apply to the substitute part?

A: The SSC1000-25-24 is ROHS3 Compliant and maintains REACH Unaffected status. Both parts are classified as EAR99 for export purposes.
