Key Parameters

Substitute Part Grouping Explanation

Substitution of the SWT862090 is based on the following critical parameters that must be evaluated for functional compatibility:

Load Voltage Range Compatibility: The substitute part must support the load voltage range of 24 V to 520 V to maintain operational compatibility with existing load circuits.

Output Type Compatibility: The substitute part must feature AC output with zero-cross switching to ensure proper operation in AC load applications and maintain electrical safety characteristics.

Mounting and Package Compatibility: The substitute part must be configured as a chassis-mount module to fit existing mechanical installations.

Manufacturer Continuity: Celduc Inc. is the original manufacturer, and substitute parts from this manufacturer ensure design consistency and technical support alignment.

Compliance and Certification: The substitute part must maintain RoHS compliance and MSL rating to meet regulatory and environmental requirements.

The identified substitute part, SGT8698503, meets these critical parameters while offering enhanced current-handling capability and active product status.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SWT862090 is obsolete and no longer manufactured. The SGT8698503 is an active product from the same manufacturer, ensuring ongoing availability, technical support, and supply chain continuity.

Compliance and Certification: Both parts maintain RoHS compliance and identical MSL ratings, meeting regulatory requirements for environmental and moisture sensitivity standards.

Electrical Compatibility: Both parts operate with AC output and zero-cross switching, supporting the same load voltage range of 24 V to 520 V. This ensures compatibility with existing load circuits and control systems.

Current Capacity: The SGT8698503 provides a rated load current of 125 A compared to the SWT862090's 32 A. This enhanced capacity allows the substitute to handle higher current loads while remaining compatible with applications requiring 32 A or less.

Circuit Configuration Difference: The SGT8698503 is configured as a 3PST-NO (3 Form A) module, providing three independent switching channels compared to the single channel of the SWT862090. Applications requiring only single-channel switching can utilize one of the three available channels.

Frequently Asked Questions (FAQ)

Q: Can the SGT8698503 directly replace the SWT862090 in existing installations?

A: The SGT8698503 is electrically compatible with the SWT862090 for applications requiring single-channel SPST-NO switching. Both parts support the same load voltage range (24 V to 520 V), AC output with zero-cross switching, and chassis-mount configuration. Mechanical mounting verification is required to confirm physical fit in the existing installation.

Q: What is the significance of the circuit configuration difference between SPST-NO and 3PST-NO?

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. For applications requiring only single-channel operation, the SGT8698503 can be used with two channels remaining unused or available for future expansion.

Q: Are the input voltage specifications compatible between these parts?

A: The SWT862090 accepts input voltage from 90 V to 240 VAC. The SGT8698503 accepts input voltage from 24 V to 255 VAC/DC. The SGT8698503 supports a broader input voltage range and includes DC input capability, providing greater flexibility in control circuit design.

Q: Do both parts meet the same regulatory and environmental standards?

A: Yes. Both the SWT862090 and SGT8698503 are RoHS compliant and carry an MSL rating of 1 (Unlimited), indicating identical compliance with environmental regulations and moisture sensitivity requirements.

Q: What is the on-state resistance specification for the SGT8698503?

A: The SGT8698503 has a maximum on-state resistance of 2 mOhms. This specification is not provided for the SWT862090 in the available documentation.

Q: How does the enhanced current capacity of the SGT8698503 affect substitution suitability?

A: The SGT8698503's rated load current of 125 A exceeds the SWT862090's 32 A rating. This higher capacity allows the substitute to safely handle applications at or below 32 A with additional margin, while also supporting higher-current applications if required in future designs.

Q: Is the cel3pac® series designation relevant to substitution decisions?

A: The cel3pac® series designation indicates the product family classification for the SGT8698503. This designation reflects Celduc Inc.'s current product line and does not affect electrical compatibility or substitution suitability for the specified parameters.
