U11MD9CLE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The U11MD9CLE is a through-hole mounted toggle switch manufactured by C&K, configured as a single-pole double-throw (SPDT) switch with on-on functionality. This component is rated for 5A at 120V AC and 28V DC, featuring epoxy sealed terminals and a brass chrome-plated actuator. The part is currently obsolete, making identification of equivalent and substitute components essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U11MD9CLE is determined by strict equivalence across the following critical parameters: circuit configuration (SPDT), switch function (On-On), current rating (5A AC/DC), voltage ratings (120V AC / 28V DC), mounting type (through hole), termination style (PC pin), and operating temperature range (-30°C to 85°C).

Two substitute parts meet these criteria:

Direct Substitute (U11MD9CRE): Identical electrical and mechanical specifications with active product status, differing only in RoHS and REACH compliance documentation.

Similar Substitute (100SP1T2B4M2QE): Meets all critical electrical parameters and mechanical mounting requirements. Variations exist in actuator length (5.08mm versus 6.86mm) and electrical life rating (40,000 cycles versus 100,000 cycles), which do not affect functional substitution within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

U11MD9CRE is the primary substitute for U11MD9CLE. Both components are from the C&K 7000 series with identical electrical and mechanical specifications. U11MD9CRE holds active product status, ensuring ongoing availability and supply chain continuity. The component maintains ROHS3 compliance and carries MSL rating 1. REACH status differs (affected versus unaffected), which may require evaluation based on end-use application and regional regulatory requirements.

100SP1T2B4M2QE from E-Switch serves as a secondary substitute when U11MD9CRE availability is constrained. This component satisfies all critical electrical parameters and mechanical mounting requirements. The actuator length differential (5.08mm versus 6.86mm) and reduced electrical life rating (40,000 cycles versus 100,000 cycles) do not affect functional equivalence within the specified parameter constraints. ROHS3 compliance and REACH unaffected status align with the original component.

Frequently Asked Questions (FAQ)

Q: Can U11MD9CRE directly replace U11MD9CLE without circuit modification?

A: Yes. U11MD9CRE is electrically and mechanically identical to U11MD9CLE across all specified parameters: SPDT configuration, 5A rating at 120V AC and 28V DC, through-hole mounting with PC pin termination, and operating temperature range of -30°C to 85°C.

Q: What is the significance of the actuator length difference in 100SP1T2B4M2QE?

A: The 100SP1T2B4M2QE features a 5.08mm actuator length compared to 6.86mm in the original component. This dimensional variation may affect panel mounting depth and operator feel. Mechanical fit verification is necessary for applications with tight panel cutout tolerances.

Q: Does the lower electrical life rating of 100SP1T2B4M2QE affect substitution suitability?

A: The 100SP1T2B4M2QE is rated for 40,000 electrical cycles versus 100,000 cycles for U11MD9CLE. Substitution suitability depends on application duty cycle requirements. Applications requiring extended cycle life should prioritize U11MD9CRE or the original component specification.

Q: Are there compliance differences between the substitute parts?

A: U11MD9CRE carries REACH affected status, while U11MD9CLE and 100SP1T2B4M2QE are REACH unaffected. Both substitute parts maintain ROHS3 compliance and MSL rating 1. Regulatory requirements for the end application determine whether REACH status is a selection factor.

Q: What packaging considerations apply to these substitutes?

A: U11MD9CLE and U11MD9CRE are supplied in standard packaging. 100SP1T2B4M2QE is supplied in bulk packaging. Procurement quantity and handling requirements may differ based on packaging format.
