Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLE1201 is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT
• Current Rating: Must support minimum 500mA AC
• Voltage Rating: Must support minimum 125V AC
• Switch Function: Must be On-On
• Mounting Type: Must be Through Hole
• Termination Style: Must be Solder Lug
• Operating Temperature Range: Must encompass -20°C to 85°C
• Regulatory Compliance: Must maintain ROHS3 compliance

The TE Connectivity ALCOSWITCH Switches part number 1825075-1 meets all substitution criteria across these parameters.

Parameter Comparison

Engineering Selection Recommendations

The 1825075-1 from TE Connectivity ALCOSWITCH Switches is a direct functional equivalent to the SLE1201. Both components share identical electrical ratings, mechanical dimensions, and operating parameters. The substitute part maintains ROHS3 compliance and operates across the same temperature range.

The primary distinction is product status: the SLE1201 is obsolete while the 1825075-1 is active. This makes the TE Connectivity part the appropriate selection for new designs and ongoing procurement requirements. Both components are suitable for applications requiring SPDT switching at 500mA and 125V AC.

Frequently Asked Questions (FAQ)

Q: Can the 1825075-1 directly replace the SLE1201 in existing designs?

A: Yes. Both components share identical electrical ratings (500mA AC, 125V), circuit configuration (SPDT), switch function (On-On), mounting type (through hole), termination style (solder lug), and actuator dimensions (4.90mm length). No circuit modifications are required.

Q: What is the difference in switch travel between these parts?

A: The SLE1201 has a switch travel of 3.90mm, while the 1825075-1 has 2.69mm. This difference does not affect electrical performance or compatibility in standard applications but may impact tactile feedback characteristics.

Q: Are there differences in contact material?

A: The SLE1201 uses brass contacts while the 1825075-1 uses copper alloy contacts. Both are finished with silver and rated for identical current and voltage specifications. This material difference does not affect substitution suitability for the specified electrical parameters.

Q: Why is the SLE1201 classified as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The 1825075-1 remains in active production and is the recommended alternative for new applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the SLE1201 and 1825075-1 are ROHS3 compliant, meeting current environmental and regulatory requirements.
