• Input voltage compatibility: 90–240VAC or broader range
• Mounting configuration: Chassis mount module
• Output switching type: AC or AC with zero-cross capability
• RoHS compliance and MSL rating

The substitute part SGT967960 maintains functional equivalence across all specified parameters while offering enhanced input voltage range and load voltage capability.

Parameter Comparison

Engineering Selection Recommendations

The SGT8879200 serves as the direct substitute for the obsolete SVT967960. Both parts are manufactured by Celduc Inc. and maintain identical SPST-NO circuit topology and 75A load current rating. The SGT8879200 is currently in active production status with 642 units in stock, ensuring supply chain continuity.

The substitute part provides enhanced specifications:

• Extended input voltage range (90–280VAC/DC versus 90–240VAC)
• Increased load voltage capability (24–640V versus 24–600V)
• Zero-cross switching capability for improved EMI performance
• Specified on-state resistance of 4.5 mOhms for thermal design calculations
• Active product status with ongoing manufacturer support

Both parts maintain RoHS compliance and MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing and storage environments. The SGT8879200 is suitable for direct replacement in applications currently using the SVT967960.

Frequently Asked Questions (FAQ)

Q: Can the SGT8879200 directly replace the SVT967960 in existing designs?

A: Yes. Both parts share identical circuit configuration (SPST-NO), load current rating (75A), mounting type (chassis mount), and package format (module). The SGT8879200 offers equal or superior electrical performance across all specified parameters.

Q: What is the significance of the zero-cross switching feature in the SGT8879200?

A: Zero-cross switching reduces electromagnetic interference (EMI) by synchronizing relay switching with AC voltage zero-crossing points. This feature is not specified for the SVT967960 but does not prevent substitution; it represents an enhancement in the active replacement part.

Q: Are there input voltage compatibility differences between these parts?

A: The SVT967960 accepts 90–240VAC input, while the SGT8879200 accepts 90–280VAC/DC input. The SGT8879200 provides a broader input range, making it suitable for applications with higher AC input voltages or DC input requirements. Applications within the 90–240VAC range operate identically on both parts.

Q: What does the on-state resistance specification mean for the SGT8879200?

A: On-state resistance (4.5 mOhms maximum) quantifies the electrical resistance when the relay is conducting. This parameter enables precise thermal and power dissipation calculations. The SVT967960 does not specify this value, but the SGT8879200 provides this data for detailed system design.

Q: Are both parts RoHS compliant?

A: Yes. Both the SVT967960 and SGT8879200 are RoHS compliant and carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the load voltage difference between these parts?

A: The SVT967960 supports 24–600V load voltage, while the SGT8879200 supports 24–640V. The SGT8879200 provides an additional 40V maximum capability, suitable for higher-voltage applications while remaining compatible with all applications within the 24–600V range.
