SLE1200 Equivalent & Substitute Parts

Part Overview

The SLE1200 is a slide switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 500mA at 125V AC. It features panel mount installation with solder lug termination and is designed for on-on switching applications. The SLE1200 is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLE1200 is determined by the following critical parameters:

• Electrical Compatibility: Circuit type (SPDT), current rating (500mA AC minimum), and voltage rating (125V AC minimum)
• Mechanical Compatibility: Panel mount configuration, solder lug termination, and actuator length (4.90mm)
• Environmental Compatibility: Operating temperature range (-20°C to 85°C), contact material with silver finish, and PBT actuator material
• Regulatory Compliance: RoHS3 compliance and ECCN classification (EAR99)

The TE Connectivity ALCOSWITCH 1825074-1 meets these core substitution criteria across all electrical and mechanical parameters, enabling direct functional replacement in applications requiring SPDT slide switch operation at specified ratings.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity ALCOSWITCH 1825074-1 provides functional equivalence to the obsolete SLE1200 for SPDT slide switch applications operating at 500mA and 125V AC. Both parts share identical electrical ratings, mechanical mounting configuration, and environmental operating parameters.

The 1825074-1 is classified as active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete SLE1200. Both parts carry EAR99 ECCN classification, maintaining consistent export compliance requirements.

Differences in switch travel (3.90mm versus 2.69mm) and electrical life rating (10,000 cycles versus 6,000 cycles) should be evaluated against specific application requirements. The SLE1200 RoHS3 compliance certification is not matched by the 1825074-1, which carries "Not Applicable" RoHS status. Applications requiring documented RoHS3 compliance should confirm regulatory requirements with the system integrator or end customer.

Frequently Asked Questions (FAQ)

Q: Can the 1825074-1 directly replace the SLE1200 in existing designs?

A: The 1825074-1 meets all core electrical and mechanical specifications for SPDT switching at 500mA and 125V AC with identical panel mount and solder lug configuration. Physical dimensions and actuator characteristics are compatible. Differences in switch travel distance and electrical life cycle rating should be confirmed against application-specific requirements before implementation.

Q: What is the significance of the different switch travel specifications?

A: The SLE1200 has 3.90mm switch travel while the 1825074-1 has 2.69mm travel. This difference affects the physical distance the actuator moves between positions. Applications with mechanical constraints or specific tactile feedback requirements should verify this parameter against design specifications.

Q: How do the electrical life ratings differ between these parts?

A: The SLE1200 is rated for 10,000 electrical cycles while the 1825074-1 is rated for 6,000 cycles. For applications requiring extended cycle life, the SLE1200 specification should be confirmed as a design requirement. The 1825074-1 may be suitable for applications with lower cycle count expectations.

Q: What is the impact of RoHS compliance differences?

A: The SLE1200 carries ROHS3 Compliant certification while the 1825074-1 shows "Not Applicable" RoHS status. Applications subject to RoHS regulatory requirements must confirm compliance documentation with the component supplier or system integrator before design release.

Q: Are there any contact material differences that affect performance?

A: The SLE1200 uses brass contacts with silver finish while the 1825074-1 uses copper alloy contacts with silver finish. Both configurations provide silver-plated contact surfaces suitable for low-voltage switching applications. Material composition differences are within acceptable parameters for equivalent electrical performance at specified ratings.
