SLS1201 Equivalent & Substitute Parts

Part Overview

The SLS1201 is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Single Pole Double Throw (SPDT) switch with a 500mA AC current rating at 125V. The switch features non-shorting contact timing, through-hole mounting, and solder lug termination. The SLS1201 is classified as an obsolete product, necessitating identification of active equivalent components for new designs and ongoing production requirements.

Identical mechanical specifications including actuator geometry, switch travel, and operating force
Equivalent contact material, finish, and terminal design
Identical operating temperature range and lifecycle ratings

The 1825075-1 is suitable for direct replacement in all applications where the SLS1201 was previously specified, with no circuit redesign or mechanical modification required.

Frequently Asked Questions (FAQ)

Q: Can the 1825075-1 be used as a direct replacement for the SLS1201 in existing designs?

A: Yes. The 1825075-1 maintains complete electrical and mechanical equivalence to the SLS1201 across all specified parameters. No circuit modifications or mechanical adjustments are required for substitution.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching circuit configuration (SPDT), current rating (500mA AC), voltage rating (125V AC), contact timing (Non-Shorting BBM), and switch function (On-On). The 1825075-1 matches all these parameters.

Q: Are there mechanical compatibility concerns with the 1825075-1?

A: No. The 1825075-1 shares identical mechanical specifications with the SLS1201, including actuator length (4.90mm), switch travel (2.69mm), mounting type (Through Hole), and termination style (Solder Lug). PCB footprints and mechanical mounting are identical.

Q: What is the difference in compliance status between these parts?

A: The SLS1201 is RoHS non-compliant, while the 1825075-1 is ROHS3 compliant. Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9050) classifications.

Q: Why is the SLS1201 listed as obsolete?

A: The SLS1201 has been discontinued by TE Connectivity ALCOSWITCH Switches. The 1825075-1 is the active replacement within the SLS series and is recommended for all new designs and ongoing production.

Q: Are the operating temperature ranges identical?

A: Yes. Both the SLS1201 and 1825075-1 operate across the identical temperature range of -20°C to 85°C.

Q: Do the mechanical and electrical life ratings differ between these parts?
