Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSC800-25-12 is determined by the following critical parameters:

• Circuit Configuration: Must remain SPST-NO (1 Form A) for direct functional replacement
• Output Type: Must be DC to maintain load switching characteristics
• Load Current Rating: Must be rated for minimum 25 A continuous operation
• Input Voltage Range: Must accommodate 8 ~ 16VDC control signal
• Mounting Type: Must be Chassis Mount for mechanical compatibility
• Termination Style: Must use Screw Terminal for connection compatibility
• Package / Case: Must be Hockey Puck form factor for physical fit

The SSC1000-25-12 qualifies as a direct substitute because it maintains all critical parameters while offering an enhanced load voltage rating (1000V vs. 800V), providing superior capability for the same application envelope.

Engineering Selection Recommendations

The SSC1000-25-12 is the qualified substitute for the obsolete SSC800-25-12. Selection is based on the following engineering criteria:

• Product Status Alignment: The SSC1000-25-12 maintains Active status, ensuring continued availability and manufacturing support, whereas the SSC800-25-12 is obsolete.
• Regulatory Compliance: Both parts maintain identical REACH and ECCN classifications, confirming equivalent regulatory standing.
• Functional Compatibility: All critical electrical and mechanical parameters remain unchanged, enabling direct substitution without circuit redesign.
• Enhanced Capability: The SSC1000-25-12 provides 200V additional load voltage headroom (1000V vs. 800V), offering improved margin for applications operating near the original 800V specification limit.

Frequently Asked Questions (FAQ)

Q: Can the SSC1000-25-12 be used as a direct replacement for the SSC800-25-12?

A: Yes. The SSC1000-25-12 maintains identical circuit configuration, input voltage range, load current rating, mounting type, termination style, and package form factor. The enhanced load voltage rating (1000V vs. 800V) provides additional capability without compromising compatibility.

Q: What are the key differences between these two parts?

A: The primary difference is the maximum load voltage specification: SSC800-25-12 supports 0 ~ 800V, while SSC1000-25-12 supports 0 ~ 1000V. Additionally, the SSC1000-25-12 is Active status with RoHS3 compliance, whereas the SSC800-25-12 is Obsolete.

Q: Are there any mechanical compatibility concerns when substituting?

A: No. Both parts use identical Hockey Puck packaging and Chassis Mount configuration, ensuring mechanical fit and mounting compatibility without modification.

Q: Does the input voltage requirement change with substitution?

A: No. Both parts require 8 ~ 16VDC input voltage, maintaining identical control signal requirements.

Q: What is the significance of the Active vs. Obsolete status?

A: The SSC1000-25-12 Active status ensures ongoing manufacturing, quality assurance, and supply chain availability. The SSC800-25-12 Obsolete status indicates discontinued production, making the SSC1000-25-12 the recommended long-term solution for new designs and system replacements.
