SVT764394 Equivalent & Substitute Parts

Part Overview

The SVT764394 is a solid-state relay (SSR) module manufactured by Celduc Inc., configured as a 3PST-NO (3 Form A) relay with 50A load current capacity and AC output. This component is classified as Obsolete and is no longer in active production. The part operates with 24VDC input control voltage and supports load voltages ranging from 24V to 520V AC.

Due to its obsolete status, sourcing new units from original manufacturing channels is limited. Identifying active equivalent parts ensures design continuity and supply chain reliability for applications requiring this relay configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SVT764394 is based on electrical and mechanical parameter alignment within the Celduc Inc. product family. The following parameters define substitution eligibility:

Critical Matching Parameters:

• Circuit configuration: 3PST-NO (3 Form A)
• Load current rating: 50 A
• Load voltage range: 24 V ~ 520 V
• Mounting type: Chassis Mount
• Package type: Module
• Manufacturer: Celduc Inc.

Acceptable Parameter Variations:

• Input voltage range: The substitute part accepts 4 ~ 30VDC input, which encompasses the original 24VDC specification
• Output type: The substitute adds Zero Cross functionality while maintaining AC output compatibility
• Termination style: Specification differences do not preclude functional substitution when mechanical integration is verified

The SGT7650500 meets all critical matching parameters and represents the active production equivalent within the Celduc Inc. portfolio.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SGT7650500

The SGT7650500 is the manufacturer-recommended equivalent for the obsolete SVT764394. This part maintains functional parity across all critical electrical parameters: 3PST-NO circuit configuration, 50A load current, 24 V ~ 520 V load voltage range, and chassis-mount module packaging.

Compliance Advantages:

The SGT7650500 carries ROHS3 Compliant certification and EAR99 ECCN classification, meeting current regulatory requirements for electronic component procurement. The original SVT764394 does not specify these compliance certifications.

Functional Enhancement:

The SGT7650500 incorporates Zero Cross switching capability in addition to standard AC output functionality. This feature provides improved electromagnetic compatibility and reduced switching noise compared to non-zero-cross designs, with no negative impact on applications designed for the original part.

Input Voltage Flexibility:

The substitute part accepts input voltage from 4 ~ 30VDC, providing a wider operating range than the original 24VDC specification. This expanded range accommodates supply voltage variations and supports broader system integration scenarios.

Active Production Status:

The SGT7650500 is in active production with confirmed inventory availability (860 units), ensuring reliable long-term sourcing compared to the obsolete SVT764394.

Frequently Asked Questions (FAQ)

Q: Can the SGT7650500 directly replace the SVT764394 in existing applications?

A: Yes. Both parts share identical circuit configuration (3PST-NO), load current rating (50A), load voltage range (24 V ~ 520 V), mounting type (Chassis Mount), and module packaging. The SGT7650500 input voltage range (4 ~ 30VDC) encompasses the original 24VDC specification, ensuring compatibility with existing control circuits.

Q: What is the difference between AC and AC with Zero Cross output?

A: The SGT7650500 provides both AC and Zero Cross switching modes. Zero Cross functionality synchronizes relay switching to the AC load voltage zero-crossing point, reducing electromagnetic interference and switching transients. Applications designed for standard AC output operate without modification when using the Zero Cross-capable substitute.

Q: Are there mechanical or dimensional differences between these parts?

A: Both parts are specified as Chassis Mount modules with identical package classification. Mechanical compatibility should be verified through dimensional drawings and mounting interface specifications during integration planning.

Q: What compliance certifications apply to the substitute part?

A: The SGT7650500 is ROHS3 Compliant and carries EAR99 ECCN classification. These certifications meet current regulatory requirements for electronic component procurement in most jurisdictions.

Q: Is the wider input voltage range of the SGT7650500 a concern for existing designs?

A: No. The 4 ~ 30VDC input range of the SGT7650500 is a superset of the original 24VDC specification. Existing control circuits designed for 24VDC input operate within the substitute part's specified range without modification.

Q: What is the on-state resistance specification for the substitute part?

A: The SGT7650500 specifies a maximum on-state resistance of 7.5 mOhms. This parameter was not provided for the original SVT764394.
