Key Parameters

Substitute Part Grouping Explanation

The substitute part SGT8698504 is identified as a manufacturer-recommended alternative to the obsolete SWT865080. Substitution eligibility is determined by the following critical parameters:

Common Substitution Criteria:

• Manufacturer: Both parts are manufactured by Celduc Inc.
• Output Type: Both devices feature AC output with zero-cross switching
• Voltage - Load: Both support the identical load voltage range of 24 V to 520 V
• Mounting Type: Both are configured for chassis mount installation
• Package / Case: Both are module-type packages
• RoHS Compliance: Both meet environmental compliance standards
• Moisture Sensitivity Level: Both are rated MSL 1 (Unlimited)

Differences in Specification:

• Circuit Configuration: SWT865080 is SPST-NO (1 Form A); SGT8698504 is 3PST-NO (3 Form A)
• Load Current: SWT865080 is rated 50 A; SGT8698504 is rated 125 A
• Input Voltage: SWT865080 accepts 24 VAC/DC; SGT8698504 accepts 24 ~ 255 VAC/DC
• Product Status: SWT865080 is obsolete; SGT8698504 is active
• Series: SGT8698504 belongs to the cel3pac® series

The SGT8698504 provides enhanced current capacity and expanded input voltage range while maintaining compatibility with the load voltage specifications and switching characteristics of the original part.

Parameter Comparison

Engineering Selection Recommendations

The SGT8698504 is the manufacturer-designated substitute for the obsolete SWT865080. Selection of this alternative is supported by the following factors:

Product Status and Availability: The SWT865080 is classified as obsolete and is no longer in active production. The SGT8698504 maintains active product status with confirmed inventory availability (1011 units in stock), ensuring reliable procurement for current and future applications.

Compliance and Certification: Both parts meet RoHS environmental compliance requirements. The SGT8698504 carries ROHS3 certification, representing the current compliance standard. Both devices are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Electrical Compatibility: The SGT8698504 maintains the identical load voltage range (24 V to 520 V) and zero-cross AC switching characteristics as the original part. The expanded input voltage range (24 ~ 255 VAC/DC versus 24 VAC/DC) and increased load current rating (125 A versus 50 A) provide enhanced operational flexibility without compromising compatibility with existing load specifications.

Physical Integration: Both parts are chassis-mount module packages, ensuring mechanical compatibility with existing mounting infrastructure and panel layouts.

Frequently Asked Questions (FAQ)

Q: Can the SGT8698504 directly replace the SWT865080 in existing applications?

A: The SGT8698504 is electrically compatible with the SWT865080 for applications requiring the original 50 A load current and 24 VAC/DC input voltage. The substitute part maintains identical load voltage range (24 V to 520 V) and zero-cross AC switching output. Both parts are chassis-mount modules. Physical mounting verification is required to confirm panel compatibility.

Q: What is the primary difference between these two parts?

A: The SWT865080 is a single-pole single-throw (SPST-NO) relay rated for 50 A, while the SGT8698504 is a three-pole single-throw (3PST-NO) relay rated for 125 A. The substitute provides three independent switching channels and higher current capacity. The SGT8698504 also accepts a wider input voltage range (24 ~ 255 VAC/DC).

Q: Why is the SWT865080 no longer available?

A: The SWT865080 is classified as obsolete and has been discontinued by the manufacturer. The SGT8698504 represents the current-generation equivalent from Celduc Inc. and is actively produced and stocked.

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

A: Both parts are RoHS compliant. The SGT8698504 carries ROHS3 certification, which is the current environmental compliance standard. Both devices are rated MSL 1 (Unlimited), indicating identical moisture sensitivity characteristics.

Q: Does the higher current rating of the SGT8698504 affect compatibility?

A: The 125 A rating of the SGT8698504 is a maximum specification. The part operates safely at the 50 A load current of the original application. Higher current capacity does not create compatibility issues in lower-current applications.

Q: What is the cel3pac® series designation?

A: The cel3pac® series is a product line designation from Celduc Inc. indicating the SGT8698504 belongs to a specific family of solid-state relay modules. This designation does not affect electrical or mechanical compatibility with the SWT865080 application requirements.
