SSC800-25-36 Equivalent & Substitute Parts

Part Overview

The SSC800-25-36 is a solid-state relay (SSR) designed for high-voltage DC switching applications. This chassis-mounted relay operates with a 36V control input and handles loads up to 800VDC at 25A continuous current. The device features a hockey puck package with screw terminal connections, making it suitable for industrial control systems requiring reliable DC switching.

The SSC800-25-36 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

Substitution of the SSC800-25-36 is determined by the following critical parameters:

• Circuit Configuration: Must remain SPST-NO (1 Form A) to maintain switching logic compatibility
• Output Type: Must be DC to match load switching requirements
• Load Current Rating: Must be rated for 25 A minimum
• Input Voltage Range: Must accept 32 ~ 40VDC control signal
• Load Voltage Capability: Must support the maximum voltage requirement of the application
• Mounting Type: Must be Chassis Mount for mechanical compatibility
• Termination Style: Must use Screw Terminal for connection compatibility
• Package / Case: Must be Hockey Puck for form factor compatibility

The SSC1000-25-36 qualifies as a direct substitute because it maintains all critical parameters while offering enhanced load voltage capability (1000V versus 800V).

Parameter Comparison

Engineering Selection Recommendations

The SSC1000-25-36 is the manufacturer-recommended substitute for the obsolete SSC800-25-36. Both devices are manufactured by Sensata Technologies (the current entity encompassing Crydom operations) and belong to the same SSC series.

The SSC1000-25-36 is classified as Active product status, ensuring ongoing availability and support. The SSC1000-25-36 is RoHS Compliant, meeting current environmental and regulatory requirements. Both parts share identical control input specifications (32 ~ 40VDC), load current rating (25 A), circuit configuration (SPST-NO), and mechanical form factor (Hockey Puck, Screw Terminal, Chassis Mount).

The primary difference is the enhanced load voltage rating: the SSC1000-25-36 supports 0 ~ 1000VDC compared to the SSC800-25-36's 0 ~ 800VDC. This increased voltage capability provides additional design margin and application flexibility without compromising compatibility with existing 800V or lower-voltage systems.

Frequently Asked Questions (FAQ)

Q: Can the SSC1000-25-36 directly replace the SSC800-25-36 in existing applications?

A: Yes. The SSC1000-25-36 maintains all critical electrical and mechanical parameters required for direct substitution. The enhanced 1000V load voltage rating is backward-compatible with applications designed for 800V operation.

Q: Are the control input voltage requirements identical?

A: Yes. Both the SSC800-25-36 and SSC1000-25-36 require 32 ~ 40VDC input voltage. No control circuit modifications are necessary.

Q: Do the mounting and termination specifications match?

A: Yes. Both devices use Chassis Mount configuration with Screw Terminal connections and Hockey Puck package form factor. Mechanical installation remains unchanged.

Q: What is the significance of the increased load voltage rating?

A: The SSC1000-25-36's 1000V capability versus the SSC800-25-36's 800V capability provides additional voltage margin. Applications operating at or below 800V remain fully compatible; applications requiring higher voltage capability benefit from the enhanced rating.

Q: Is the SSC1000-25-36 RoHS compliant?

A: Yes. The SSC1000-25-36 is RoHS Compliant, meeting current environmental regulations. The SSC800-25-36 status is not specified in available documentation.

Q: What is the current availability status?

A: The SSC800-25-36 is obsolete with limited inventory. The SSC1000-25-36 is Active product status with current manufacturing support and availability.
