SVT965760 Equivalent & Substitute Parts

Part Overview

The SVT965760 is a Solid State Relay (SSR) manufactured by Celduc Inc., configured as a SPST-NO (1 Form A) module with a 50A load capacity and operating voltage range of 24V to 600V. This component is classified as obsolete and is no longer in active production. Due to its obsolete status, identification of equivalent substitute components is necessary for system maintenance, repair, and new design implementations where this functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SVT965760 is based on the following critical electrical and mechanical parameters:

Load Current Capacity: Both the main part and substitute maintain a 50A load current rating, ensuring equivalent power handling capability.

Voltage Operating Range: The main part operates with load voltages from 24V to 600V. The substitute part (SGT8858200) operates from 24V to 640V, providing an extended upper voltage limit while maintaining the minimum 24V threshold.

Input Voltage Compatibility: The SVT965760 accepts 10~30VAC/DC input control voltage. The substitute part accepts 24~255VAC/DC input voltage, representing a different control voltage specification.

Mounting and Package: Both components are chassis-mounted modules, maintaining identical form factor and installation methodology.

Output Type and Circuit Configuration: The main part is SPST-NO (single pole, single throw, normally open). The substitute part is 3PST-NO (three pole, single throw, normally open), providing three independent switching channels instead of one.

Compliance and Status: The SVT965760 is obsolete; the substitute SGT8858200 is active production with current RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The SGT8858200 is the manufacturer-recommended substitute for the obsolete SVT965760. Both components are manufactured by Celduc Inc. and maintain RoHS compliance certification.

Electrical Compatibility: The substitute maintains the 50A load current capacity and 24V minimum load voltage threshold. The extended maximum load voltage (640V versus 600V) provides additional operational margin. The substitute includes zero-cross detection in its AC output type, which is an enhancement over the base SVT965760 specification.

Control Voltage Consideration: The input voltage range differs between the two parts. The SVT965760 accepts 10~30VAC/DC control input, while the SGT8858200 requires 24~255VAC/DC control input. System control voltage must be verified to fall within the substitute's specified range.

Circuit Configuration Difference: The SVT965760 provides one switching channel (SPST-NO), while the SGT8858200 provides three independent switching channels (3PST-NO). Applications requiring single-channel switching must account for the additional channels present in the substitute, which do not require activation if unused.

Product Status: The substitute is in active production with current manufacturer support and availability, addressing the obsolescence of the original part.

Frequently Asked Questions (FAQ)

Q: Can the SGT8858200 directly replace the SVT965760 in all applications?

A: Direct replacement requires verification of two critical parameters: (1) the system control voltage must fall within the SGT8858200's input range of 24~255VAC/DC, and (2) the application must accommodate the three-channel configuration of the substitute, even if only one channel is utilized.

Q: What is the significance of the zero-cross detection feature in the SGT8858200?

A: Zero-cross detection is an output characteristic that synchronizes relay switching with the AC voltage waveform zero-crossing point. This feature reduces electromagnetic interference and switching transients compared to non-zero-cross designs.

Q: Are both parts RoHS compliant?

A: Yes, both the SVT965760 and SGT8858200 are RoHS compliant. The substitute maintains this compliance standard.

Q: What is the difference between SPST-NO and 3PST-NO circuit configurations?

A: SPST-NO (Single Pole, Single Throw, Normally Open) provides one independent switching channel. 3PST-NO (Three Pole, Single Throw, Normally Open) provides three independent switching channels. Each channel operates independently and can switch separate loads.

Q: Does the extended load voltage range of the SGT8858200 (640V versus 600V) affect compatibility?

A: The extended range is backward compatible with applications operating at or below 600V. Applications operating between 600V and 640V can utilize the additional voltage capability of the substitute.

Q: What is the moisture sensitivity level (MSL) for both parts?

A: Both the SVT965760 and SGT8858200 have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Is the on-state resistance specification critical for substitution?

A: The SVT965760 does not provide an on-state resistance specification. The SGT8858200 specifies a maximum on-state resistance of 7.5 mOhms. For applications where on-state resistance is a design parameter, the SGT8858200 specification should be verified against system requirements.
