Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SWT862030 is based on the following critical parameters that must be evaluated for functional compatibility:

Input Voltage Compatibility: The substitute part must accept the same control signal voltage range (24VAC/DC) to interface with existing control circuits without modification.

Load Voltage Range: The substitute must support the full load voltage range of 24V to 520V to maintain operational compatibility across all intended applications.

Output Switching Type: The substitute must provide AC output with zero-cross switching capability to preserve the electrical characteristics required by the load circuit.

Mounting Configuration: The substitute must utilize Chassis Mount configuration to ensure physical compatibility with existing enclosure designs.

Regulatory Compliance: The substitute must maintain RoHS Compliance status to satisfy current environmental and regulatory requirements.

The identified substitute part SGT8698503 shares the core input voltage, load voltage range, output type, mounting type, and compliance certifications with the SWT862030. However, the substitute differs in circuit configuration (3PST-NO versus SPST-NO) and load current capacity (125A versus 32A), representing a higher-capability alternative within the Celduc Inc. product family.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SWT862030 is classified as Obsolete, making SGT8698503 the active alternative from Celduc Inc. The substitute part maintains Active product status, ensuring ongoing manufacturer support, availability, and compliance with current standards.

Compliance and Certification: Both parts maintain RoHS Compliance and MSL Level 1 (Unlimited) ratings. The SGT8698503 carries ECCN EAR99 and HTSUS 8536.49.0080 classifications, indicating current regulatory alignment.

Electrical Compatibility: The SGT8698503 accepts input voltage from 24V to 255VAC/DC, which encompasses the 24VAC/DC requirement of the SWT862030. The load voltage range (24V to 520V) and output switching type (AC, Zero Cross) are identical, ensuring compatibility with existing load circuits.

Circuit Configuration Difference: The SGT8698503 provides 3PST-NO (3 Form A) configuration compared to the SPST-NO (1 Form A) of the SWT862030. This represents an increase in switching poles and provides additional switching capability. Applications requiring only single-pole switching can utilize one of the three available poles, with remaining poles left unused or available for future expansion.

Current Capacity: The SGT8698503 provides 125A load current capacity versus 32A in the SWT862030. This higher rating provides design margin and supports applications with increased current requirements without requiring additional parallel switching stages.

Frequently Asked Questions (FAQ)

Q: Can the SGT8698503 directly replace the SWT862030 in existing applications?

A: The SGT8698503 shares identical load voltage range (24V to 520V), output switching type (AC, Zero Cross), and mounting configuration (Chassis Mount). The input voltage range of SGT8698503 (24V to 255VAC/DC) encompasses the SWT862030 requirement (24VAC/DC). Physical and electrical integration is compatible. The 3PST-NO configuration provides three switching poles; applications requiring single-pole switching utilize one pole with remaining poles available or unused.

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 switching contact. 3PST-NO (Three Pole Single Throw Normally Open) provides three independent switching contacts. The SGT8698503 can perform all functions of the SWT862030 using a single pole, with two additional poles available for simultaneous control of additional loads or future system expansion.

Q: Are there input voltage compatibility concerns?

A: The SWT862030 operates with 24VAC/DC input. The SGT8698503 accepts 24V to 255VAC/DC input, which includes the 24VAC/DC specification. No input voltage compatibility issues exist for this substitution.

Q: Does the higher load current rating of SGT8698503 affect applications designed for 32A?

A: No. The SGT8698503 is rated for 125A maximum load current. Applications operating at 32A load current operate well within the SGT8698503 specification and benefit from additional design margin and thermal headroom.

Q: Are packaging and mounting considerations identical?

A: Both parts are Module package type with Chassis Mount configuration. Physical mounting compatibility is maintained. Verify connector and terminal specifications for your specific application to confirm complete mechanical compatibility.

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

A: The SGT8698503 specifies a maximum on-state resistance of 2 mOhms. This parameter was not provided for the SWT862030 in the available documentation.
