SVT864994 Equivalent & Substitute Parts

Part Overview

The SVT864994 is a solid-state relay (SSR) module manufactured by Celduc Inc., configured as a 3PST-NO (3 Form A) relay with 50A load capacity and operating voltage range of 24V to 520V. This component is classified as obsolete and is no longer in active production. Due to its obsolete status, identification of equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SVT864994 is based on electrical and mechanical parameter equivalence within the Celduc Inc. product family. The substitute part must satisfy the following critical parameters:

• Circuit Configuration: 3PST-NO (3 Form A) topology
• Load Current Rating: 50 A minimum
• Load Voltage Range: 24 V ~ 520 V compatibility
• Output Type: AC with Zero Cross switching
• Mounting Type: Chassis Mount
• Package Type: Module form factor

The identified substitute part SGT8658500 maintains functional equivalence across all load-side electrical parameters and mechanical mounting requirements. Input voltage specifications differ between the two parts; however, this difference does not preclude substitution when the control circuit voltage is within the substitute part's input range of 24 ~ 255VAC/DC.

Parameter Comparison

Engineering Selection Recommendations

The SGT8658500 is the manufacturer-recommended substitute for the obsolete SVT864994. Both components are manufactured by Celduc Inc. and share identical load-side electrical specifications and mechanical mounting characteristics. The substitute part is currently in active production status with confirmed inventory availability.

The SGT8658500 offers additional compliance benefits, including RoHS compliance certification, which may be required for new system designs or regulatory compliance applications. The input voltage range of the substitute part (24 ~ 255VAC/DC) encompasses the original part's input specification (90 ~ 240VAC) when the control circuit operates within the overlapping range of 90 ~ 240VAC.

Selection of SGT8658500 as a replacement for SVT864994 is appropriate for applications requiring equivalent load switching capacity, circuit topology, and mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can SGT8658500 directly replace SVT864994 in existing installations?

A: Yes. Both parts share identical circuit configuration (3PST-NO), load current rating (50A), load voltage range (24V–520V), output type (AC, Zero Cross), and mounting type (Chassis Mount). The substitute part is mechanically and electrically compatible for load-side operation.

Q: What is the difference in input voltage specifications between these parts?

A: SVT864994 accepts 90–240VAC input, while SGT8658500 accepts 24–255VAC/DC input. The substitute part's range is broader and includes DC input capability. For applications operating within the 90–240VAC range, both parts are functionally equivalent.

Q: Is the SGT8658500 available in the same package type?

A: Yes. Both parts are supplied in Module form factor with Chassis Mount configuration. The SGT8658500 is packaged in a Box, while the original part packaging is not specified.

Q: Does the SGT8658500 have any additional certifications?

A: The SGT8658500 is RoHS Compliant and carries ECCN classification EAR99 with HTSUS code 8536.49.0080. The original SVT864994 does not list these certifications.

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

A: The SGT8658500 has a maximum on-state resistance of 7.5 mOhms. This specification is not provided for the original SVT864994.

Q: Are there any termination differences between the two parts?

A: The SVT864994 specifies Screw Terminal termination. The SGT8658500 termination style is not specified in the provided data.
