Substitute Part Grouping Explanation

Substitution of the obsolete SVT868994 is based on electrical and mechanical compatibility within the following criteria:

Circuit Configuration: Both the main part and substitute maintain identical 3PST-NO (3 Form A) circuit topology, ensuring pin-compatible relay switching functionality.

Output Characteristics: Both devices support AC output with zero-cross switching and operate across the same load voltage range of 24–520 V, maintaining compatibility with existing load circuits.

Mounting and Termination: Both parts are chassis-mount modules with module-type packaging, preserving mechanical fit within existing enclosures.

Load Current Capacity: The substitute part (SGT8698500) provides 125 A load current capacity, which exceeds the original 50 A specification. This higher rating ensures the substitute can handle all applications designed for the original part without current-related limitations.

Input Control Voltage: The substitute accepts 24–255 VAC/DC input, which encompasses the original 90–240 VAC range, ensuring compatibility with existing control circuits.

Compliance and Availability: The substitute is active, RoHS compliant, and maintains unlimited moisture sensitivity rating, supporting modern procurement and environmental standards.

Parameter Comparison

Engineering Selection Recommendations

The SGT8698500 is the manufacturer-recommended substitute for the obsolete SVT868994. Selection of this part is based on the following engineering criteria:

Product Status Alignment: The substitute is active and currently manufactured, ensuring long-term availability and supply chain continuity for new designs and field service applications.

Electrical Compatibility: The substitute maintains identical circuit configuration (3PST-NO), output switching characteristics (AC, zero-cross), and load voltage range (24–520 V). The enhanced load current rating of 125 A provides margin above the original 50 A specification, eliminating current-related constraints in all applications designed for the original part.

Input Voltage Coverage: The substitute input range of 24–255 VAC/DC fully encompasses the original 90–240 VAC specification, ensuring compatibility with existing control voltage sources.

Mechanical Compatibility: Both parts are chassis-mount modules with identical package types, supporting direct mechanical substitution in existing enclosures without redesign.

Compliance Status: The substitute is RoHS compliant, meeting modern environmental and procurement standards. Both parts maintain unlimited moisture sensitivity rating, indicating robust performance in standard industrial environments.

Series Designation: The substitute belongs to the cel3pac® series, representing current-generation Celduc solid-state relay technology.

Frequently Asked Questions (FAQ)

Q: Can the SGT8698500 directly replace the SVT868994 in existing applications?

A: Yes. Both parts share identical circuit configuration (3PST-NO), output type (AC, zero-cross), load voltage range (24–520 V), mounting type (chassis mount), and package type (module). The substitute's 125 A load current rating exceeds the original 50 A specification, ensuring compatibility with all applications designed for the SVT868994.

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

A: The SVT868994 accepts 90–240 VAC input, while the SGT8698500 accepts 24–255 VAC/DC input. The substitute range fully encompasses the original specification and extends to lower and higher voltage limits, providing greater flexibility in control circuit design.

Q: Why is the load current rating higher on the substitute part?

A: The SGT8698500 provides 125 A load current capacity compared to the original 50 A. This higher rating represents an enhancement in the current-generation cel3pac® series design and does not affect compatibility. Applications requiring 50 A or less operate within the substitute's rated capacity.

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

A: The SVT868994 specifies screw terminal termination. The SGT8698500 termination style is not specified in the provided data. Mechanical fit and electrical connection compatibility are maintained through identical module package type and chassis-mount configuration.

Q: Is the substitute RoHS compliant?

A: Yes. The SGT8698500 is RoHS compliant, meeting environmental and regulatory requirements for modern industrial applications. The original SVT868994 RoHS status is not specified.

Q: What is the moisture sensitivity rating for the substitute?

A: The SGT8698500 maintains MSL 1 (Unlimited) moisture sensitivity rating, identical to the original part. This rating indicates the component requires no special moisture control during storage, handling, or installation.

Q: Are both parts manufactured by the same company?

A: Yes. Both the SVT868994 and SGT8698500 are manufactured by Celduc Inc., ensuring consistent design philosophy, quality standards, and technical support.
