TE Connectivity ALCOSWITCH 3-1825142-1 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The TE Connectivity ALCOSWITCH 3-1825142-1 is an active-status toggle switch featuring Single Pole Double Throw (SPDT) circuit configuration with On-Off-On switching function. This through-hole mounted component is rated for 5A at 120V AC and 28V DC operation, designed for applications requiring sealed, waterproof switching in industrial and commercial environments. The Gemini AE series component operates across -30°C to 85°C with IP67 ingress protection and process-sealed construction.

Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable, when inventory constraints exist, or when application-specific requirements necessitate alternative electrical or mechanical characteristics within compatible parameter ranges.

Substitute Part Grouping Explanation

Substitute part identification for the TE Connectivity ALCOSWITCH 3-1825142-1 is based on strict electrical and mechanical parameter compatibility within the toggle switch SPDT category. The following criteria establish substitution validity:

Primary Compatibility Criteria:

Circuit configuration must be SPDT with On-Off-On switching function to maintain electrical functionality equivalence. Mounting type must be through-hole to ensure PCB assembly compatibility. Actuator type and length (Standard Round, 12.70mm) must match to preserve panel cutout and mechanical interface requirements. Termination style must be PC Pin for footprint compatibility.

Electrical Parameter Constraints:

Current rating of substitute must equal or exceed 5A to handle application current demands. Voltage ratings must support both AC and DC operation at or above 120V AC and 28V DC respectively. Operating temperature range must encompass the -30°C to 85°C specification.

Environmental and Regulatory Requirements:

Ingress protection rating must maintain IP67 or equivalent sealed/waterproof characteristics. RoHS3 compliance is mandatory for regulatory alignment. Product status must be Active to ensure ongoing availability and manufacturer support.

Identified Substitute:

The C&K E103SD1CBE meets the core circuit, mounting, and mechanical requirements as an SPDT through-hole toggle switch with Standard Round actuator at 12.70mm length and PC Pin termination. However, this substitute operates at reduced electrical ratings (0.4VA at 20V AC/DC) and therefore is suitable only for applications with lower power requirements than the primary part specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection:

The TE Connectivity ALCOSWITCH 3-1825142-1 remains the specified component for applications requiring 5A current capacity at 120V AC or 28V DC operation. This part is Active status with full manufacturer support, ROHS3 compliance, and REACH compliance documentation. The IP67 ingress protection rating and process-sealed construction provide maximum environmental protection for sealed switching applications.

Substitute Part Applicability:

The C&K E103SD1CBE is suitable as a substitute only when application electrical requirements are reduced to 0.4VA maximum at 20V AC/DC operation. This substitute maintains mechanical and circuit compatibility through identical SPDT configuration, On-Off-On function, through-hole mounting, Standard Round actuator at 12.70mm, and PC Pin termination. The substitute provides equivalent operating temperature range (-30°C to 85°C) and RoHS3 compliance.

Electrical Derating Consideration:

The C&K E103SD1CBE operates at significantly reduced electrical ratings compared to the primary part. Applications must verify that actual circuit current does not exceed 0.4A and that AC/DC voltages remain below 20V. The substitute's IP57 rating provides dust protection and waterproofing but does not achieve the IP67 level of the primary part.

Compliance and Availability:

Both components maintain Active product status with ROHS3 compliance and REACH compliance status. Selection between primary and substitute parts should be based on electrical requirement alignment and environmental sealing level requirements rather than regulatory or availability factors.

Frequently Asked Questions (FAQ)

Q: Can the C&K E103SD1CBE directly replace the TE Connectivity 3-1825142-1 in all applications?

A: No. The C&K E103SD1CBE is mechanically and functionally compatible but electrically derated. Direct replacement is valid only when application current does not exceed 0.4A and AC/DC voltages remain below 20V. Applications requiring 5A at 120V AC or 28V DC must use the primary TE Connectivity part.

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

A: Both components share identical mechanical specifications: through-hole mounting, Standard Round actuator type, 12.70mm actuator length, and PC Pin termination. These parameters ensure equivalent panel cutout compatibility and PCB footprint alignment.

Q: How do the ingress protection ratings differ between these parts?

A: The TE Connectivity 3-1825142-1 provides IP67 protection (dust tight, waterproof), while the C&K E103SD1CBE provides IP57 protection (dust protected, waterproof). IP67 offers superior dust exclusion for sealed applications; IP57 is suitable for dust-protected environments with water exposure.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TE Connectivity 3-1825142-1 and C&K E103SD1CBE are ROHS3 compliant, meeting restricted substance requirements for electronic component manufacturing.

Q: What is the significance of the different electrical life ratings?

A: The TE Connectivity 3-1825142-1 is rated for 6,000 electrical cycles, while the C&K E103SD1CBE is rated for 40,000 cycles. The substitute offers extended cycle life, which may provide longer operational life in high-cycle-count applications operating within its electrical rating limits.

Q: Can packaging differences affect component selection?

A: The TE Connectivity 3-1825142-1 is supplied in Bulk packaging, while the C&K E103SD1CBE is supplied in Tray packaging. Packaging affects inventory management and handling procedures but does not impact electrical or mechanical compatibility.

Q: What is the primary limiting factor for using the C&K E103SD1CBE as a substitute?

A: The electrical rating differential is the primary limiting factor. The substitute's 0.4VA rating at 20V AC/DC is substantially lower than the primary part's 5A at 120V AC/28V DC. Applications must operate within the substitute's electrical envelope for valid substitution.

Q: Are there any temperature-related compatibility concerns?

A: No. Both components operate across the identical temperature range of -30°C to 85°C, providing thermal compatibility for applications within this envelope.
