Substitute Part Grouping Explanation

The SVT867394 can be substituted with the SGT8670500 based on the following critical parameters that determine functional equivalence:

Load Current Capacity: Both parts maintain 75A load current rating, ensuring identical current-handling capability.

Load Voltage Range: Both parts support 24V to 520V AC load voltage, providing equivalent operational voltage compatibility.

Output Type: Both parts feature AC output with zero-cross switching, maintaining identical switching characteristics and load protection mechanisms.

Mounting Type: Both parts are chassis-mounted modules, ensuring mechanical compatibility with existing installations.

RoHS Compliance: Both parts meet RoHS requirements, satisfying regulatory and environmental standards.

Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) rating, indicating equivalent environmental robustness.

The primary difference is circuit configuration: the SVT867394 is SPST-NO (single pole), while the SGT8670500 is 3PST-NO (three pole). This substitution is valid when the application requires or can accommodate the additional switching poles without functional conflict.

Parameter Comparison

Engineering Selection Recommendations

The SGT8670500 is the manufacturer-recommended substitute for the obsolete SVT867394. Selection of this alternative is based on the following engineering criteria:

Product Status Alignment: The SGT8670500 carries Active product status, ensuring ongoing manufacturer support, availability, and compliance with current industry standards. The SVT867394 is obsolete and no longer supported.

Regulatory Compliance: Both parts maintain RoHS Compliant status, satisfying environmental and regulatory requirements for new designs and field replacements.

Electrical Equivalence: The SGT8670500 maintains identical load current (75A), load voltage range (24V–520V), and output switching characteristics (AC, zero-cross). The input voltage range of the SGT8670500 (4–30VDC) encompasses the SVT867394 specification (24VDC), providing broader operational flexibility.

Mechanical Compatibility: Chassis mount configuration and module package type remain consistent, supporting direct integration into existing mechanical designs.

Circuit Configuration Consideration: The SGT8670500 provides three switching poles (3PST-NO) compared to the single pole (SPST-NO) of the SVT867394. Applications requiring single-pole switching can utilize one of the three available poles, with remaining poles left unused or configured for additional switching functions as needed.

Frequently Asked Questions (FAQ)

Q: Can the SGT8670500 directly replace the SVT867394 in all applications?

A: The SGT8670500 maintains electrical equivalence in load current, load voltage range, and switching characteristics. The primary difference is circuit configuration: SGT8670500 provides three switching poles versus one in the SVT867394. Applications requiring single-pole switching can utilize one pole of the SGT8670500. Verify that the additional poles do not create functional conflicts in your specific circuit design.

Q: What is the significance of the input voltage difference between these parts?

A: The SVT867394 specifies 24VDC input, while the SGT8670500 accepts 4–30VDC input. The SGT8670500 provides broader input voltage tolerance, allowing operation across a wider range of control voltage sources. If your control circuit supplies exactly 24VDC, both parts operate identically. If control voltage varies between 4–30VDC, the SGT8670500 offers enhanced flexibility.

Q: Are there mechanical compatibility concerns when substituting these parts?

A: Both parts are chassis-mounted modules with identical package type. No mechanical redesign is required for substitution. Verify that terminal configurations and mounting hole patterns align with your existing installation before final integration.

Q: Why is the SVT867394 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support for this part. The SGT8670500 represents the active alternative within Celduc Inc.'s product portfolio, ensuring access to current manufacturing, technical support, and compliance with evolving industry standards.

Q: Does the on-state resistance specification affect substitution suitability?

A: The SGT8670500 specifies maximum on-state resistance of 4.5 mOhms. This parameter defines voltage drop and heat dissipation during operation. If your application has thermal or voltage drop constraints, the specified on-state resistance of the SGT8670500 should be evaluated against your system requirements. The SVT867394 on-state resistance is not provided in available documentation.

Q: What is the cel3pac® series designation?

A: cel3pac® is the Celduc Inc. product series identifier for the SGT8670500. This designation indicates the part belongs to a specific product family with defined electrical and mechanical characteristics. The SVT867394 series designation is not specified in available documentation.
