UE10-3OS2D0 Equivalent & Substitute Parts

Part Overview

The UE10-3OS2D0 is a safety relay manufactured by SICK, Inc., configured as a 5PST (5-pole single-throw) unit with 6A contact rating and 24VDC coil voltage. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component procurement. The relay features screw terminal connections and operates at 20ms response time with silver and gold contact materials suitable for industrial safety applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete UE10-3OS2D0 requires matching the following critical electrical and mechanical parameters:

Primary Matching Criteria:

• Coil voltage: 24VDC
• Mounting type: DIN Rail
• Contact material composition: Silver and Gold
• Manufacturer: SICK, Inc.
• Switching voltage capability: minimum 230VAC/300VDC
• Contact rating: 6A minimum

Secondary Considerations:

• Contact form configuration (pole and throw arrangement)
• Termination style compatibility
• Operate time performance
• Product status (active vs. obsolete)

The substitute parts RLY3-OSSD1 and RLY3-OSSD400 share the core electrical specifications (24VDC coil, 6A contact rating, DIN Rail mounting, silver/gold contacts) but differ in contact configuration and operational characteristics. Both are active products from SICK, Inc., providing long-term availability advantages over the obsolete UE10-3OS2D0.

Parameter Comparison

Engineering Selection Recommendations

RLY3-OSSD1 Selection Criteria:

• Suitable when circuit design requires 3PST configuration (2 Form A, 1 Form B contacts)
• Active product status ensures ongoing availability and supply chain continuity
• RoHS3 compliant and REACH unaffected, meeting modern regulatory requirements
• Faster operate time (10ms vs. 20ms) may improve system response characteristics
• Lower coil current (50mA vs. 500mA) reduces power consumption
• Spring terminal termination requires circuit board layout verification

RLY3-OSSD400 Selection Criteria:

• Suitable when circuit design requires four independent Form A (SPST-NO) contacts
• Active product status with established supply chain
• RoHS3 compliant and REACH unaffected
• Operating temperature range specified (-25°C ~ 55°C) provides environmental performance data
• Coil power and resistance parameters documented (1.4W, 400 Ohms)
• Spring terminal termination requires circuit board layout verification

Compatibility Constraints: Both substitute parts employ spring terminal connections versus the screw terminal design of UE10-3OS2D0. Circuit board modifications may be required. Contact form differences necessitate circuit schematic review to confirm pole and throw requirements align with application needs.

Frequently Asked Questions (FAQ)

Q: Can RLY3-OSSD1 or RLY3-OSSD400 directly replace UE10-3OS2D0 without circuit modification?

A: Direct mechanical and electrical replacement depends on contact form requirements. The UE10-3OS2D0 provides 5PST configuration (3 Form A, 2 Form B). RLY3-OSSD1 provides 3PST (2 Form A, 1 Form B), and RLY3-OSSD400 provides four independent Form A contacts. Circuit schematic verification is required to confirm the substitute contact arrangement matches application requirements. Termination style change from screw to spring terminal requires board layout assessment.

Q: What are the key electrical parameters that determine substitutability?

A: Core electrical parameters are coil voltage (24VDC), contact rating (6A), switching voltage capability (minimum 230VAC/300VDC), and contact material composition (silver/gold). All three relays meet these criteria. Secondary parameters including operate time, coil current, and contact form configuration must be evaluated against specific circuit requirements.

Q: Why do the substitute parts have lower coil current than the original?

A: RLY3-OSSD1 (50mA) and RLY3-OSSD400 (60mA) represent different relay designs within the SICK product family. Lower coil current indicates improved power efficiency in the substitute designs. Circuit power supply capability must be verified to ensure adequate current delivery at 24VDC.

Q: Are there packaging or inventory considerations?

A: UE10-3OS2D0 is obsolete with 991 pieces in stock. RLY3-OSSD1 is active with 743 pieces available in bulk packaging. RLY3-OSSD400 is active with 749 pieces available in bulk packaging. Active product status ensures long-term procurement viability.

Q: What compliance certifications apply to these relays?

A: All three relays carry EAR99 export classification and 8536.41.0020 HTSUS code. RLY3-OSSD1 and RLY3-OSSD400 are RoHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.
