Key Parameters

Substitute Part Grouping Explanation

Substitution of the UE10-4XT2D2 is determined by the following critical parameters:

• Coil Voltage Compatibility: The substitute must operate at 24VDC or 24VAC/DC to maintain circuit compatibility
• Contact Configuration: The substitute must provide equivalent switching capability through Form A (NO) and Form B (NC) contact arrangements
• Current Rating: Minimum 6A contact rating required for load switching
• Mounting Standard: DIN Rail mounting ensures mechanical compatibility with existing enclosure infrastructure
• Switching Voltage Capability: Maximum switching voltage of 230VAC and 300VDC establishes the upper operational envelope
• Termination Interface: Connection method must be compatible with existing wiring infrastructure

The RLY3-OSSD400 meets these substitution criteria as an active product from the same manufacturer, providing equivalent electrical performance within the specified parameter ranges.

Engineering Selection Recommendations

The RLY3-OSSD400 is the designated substitute for the obsolete UE10-4XT2D2. Selection is based on the following engineering criteria:

• Product Status: The RLY3-OSSD400 maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both components share identical ECCN (EAR99) and HTSUS (8536.41.0020) classifications, maintaining export and tariff compliance
• Electrical Equivalence: The substitute operates at 24VDC within the 24VAC/DC envelope of the original part, with matching 6A contact rating and compatible switching voltage specifications
• Mechanical Compatibility: DIN Rail mounting on both components ensures direct installation compatibility within existing enclosure designs
• Contact Material Consistency: Identical silver and gold contact materials preserve electrical performance characteristics

Frequently Asked Questions (FAQ)

Q: Can the RLY3-OSSD400 directly replace the UE10-4XT2D2 in existing installations?

A: Direct mechanical replacement is possible due to identical DIN Rail mounting. However, the contact configuration differs: the UE10-4XT2D2 provides 7PST (4 Form A, 3 Form B) contacts, while the RLY3-OSSD400 provides 4 Form A contacts only. Circuit redesign may be required if Form B (NC) contacts are essential to system operation.

Q: What is the difference in operate time between these components?

A: The UE10-4XT2D2 operates in 70 ms, while the RLY3-OSSD400 operates in 12 ms. The faster response time of the substitute may affect timing-sensitive circuits and should be evaluated against system requirements.

Q: Are there termination compatibility considerations?

A: The UE10-4XT2D2 uses screw terminals, while the RLY3-OSSD400 uses spring terminals. Existing wiring connections must be adapted to the spring terminal interface of the substitute.

Q: Does the RLY3-OSSD400 support 24VAC operation?

A: The RLY3-OSSD400 is specified for 24VDC operation only. If the original circuit requires 24VAC capability, alternative substitutes must be evaluated.

Q: What is the inventory status of these components?

A: The UE10-4XT2D2 has 900 pieces in stock as new original inventory. The RLY3-OSSD400 has 749 pieces in stock as new original inventory.
