U211SD9AV2QE Toggle Switch SP3T Equivalent & Substitute Parts

Part Overview

The U211SD9AV2QE is an active production toggle switch manufactured by C&K, classified as a single-pole triple-throw (SP3T) switch rated for 5A at 120V AC and 28V DC. This through-hole, right-angle vertical mount component features a standard round actuator with PC pin termination and is designed for applications requiring three distinct switch positions with On-On-On functionality. The part is ROHS3 compliant and REACH affected, with an electrical life rating of 40,000 cycles and operating temperature range of -30°C to 85°C.

Substitute parts are identified when equivalent circuit configurations, mounting styles, termination methods, and environmental ratings align with the main part specifications, enabling direct replacement in compatible applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U211SD9AV2QE is determined by the following critical parameters:

• Circuit configuration must be SP3T with On-On-On switching function
• Mounting method must be through-hole with right-angle vertical orientation
• Termination style must be PC pin
• Actuator type must be standard round
• Operating temperature range must encompass or match -30°C to 85°C
• Product status must be active production
• RoHS and REACH compliance status must be documented

The substitute part 100DP6T1B4M7RE manufactured by E-Switch meets these structural and functional criteria. However, electrical ratings differ: the substitute is rated at 0.4VA (20V AC/DC) compared to the main part's 5A (120V AC/28V DC). This lower power rating restricts the substitute to applications with reduced current and voltage requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the U211SD9AV2QE and 100DP6T1B4M7RE are active production components with ROHS3 compliance and identical operating temperature ranges. The primary selection criterion is electrical rating compatibility with the application circuit.

The U211SD9AV2QE is suitable for applications requiring 5A switching capacity at 120V AC or 28V DC. The 100DP6T1B4M7RE is suitable for low-power applications with maximum ratings of 0.4VA at 20V AC/DC. Direct substitution of the E-Switch part for the C&K part is valid only when application voltage and current requirements do not exceed 20V and 0.4VA respectively.

Both parts share identical circuit topology, mounting configuration, termination method, and environmental specifications, ensuring mechanical and functional compatibility within their respective electrical rating boundaries.

Frequently Asked Questions (FAQ)

Q: Can the 100DP6T1B4M7RE replace the U211SD9AV2QE in all applications?

A: No. The 100DP6T1B4M7RE has lower electrical ratings (0.4VA at 20V AC/DC versus 5A at 120V AC/28V DC). Substitution is valid only for applications operating within the E-Switch part's electrical limits.

Q: What are the key compatibility factors between these parts?

A: Both parts share SP3T circuit configuration, On-On-On switching function, through-hole right-angle vertical mounting, PC pin termination, standard round actuator, -30°C to 85°C operating temperature range, 40,000 cycle electrical life, and ROHS3 compliance.

Q: How do the actuator lengths differ?

A: The U211SD9AV2QE has a 12.45mm actuator length, while the 100DP6T1B4M7RE has a 10.41mm actuator length. This 2.04mm difference may affect panel cutout alignment and actuator engagement in space-constrained designs.

Q: Are there packaging differences between these parts?

A: Yes. The U211SD9AV2QE is supplied in trays, while the 100DP6T1B4M7RE is supplied in bulk packaging. This affects inventory management and component handling procedures.

Q: What is the significance of REACH compliance status differences?

A: The U211SD9AV2QE is REACH affected, while the 100DP6T1B4M7RE is REACH unaffected. Applications subject to REACH regulations must verify compliance requirements with the specific supply chain and end-use jurisdiction.
