SLA2201 Equivalent & Substitute Parts

Part Overview

The SLA2201 is a slide switch with DPDT (Double Pole Double Throw) configuration manufactured by APEM Inc. It is rated for 500mA at 125V AC and features through-hole mounting with PC pin termination. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLA2201 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Current rating must support minimum 500mA AC
• Voltage rating must support minimum 125V AC

Mechanical Compatibility Requirements:

• Mounting type must be Through Hole
• Actuator type must be Standard
• Actuator length tolerance: 4.75mm to 4.80mm
• Switch travel tolerance: 2.67mm to 2.70mm
• Operating force: 350gf

Environmental & Compliance Requirements:

• Operating temperature range must encompass -20°C to 85°C
• RoHS3 compliance required
• REACH compliance status acceptable if unaffected or vendor-defined

Two substitute parts meet these criteria: the TE Connectivity ALCOSWITCH 1825087-1 and the CW Industries GS-113-0045.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity ALCOSWITCH 1825087-1 is the primary substitute for the SLA2201. This part maintains identical electrical ratings, actuator dimensions, and operating temperature range. The termination style differs (Solder Turret versus PC Pin), requiring PCB layout adjustment. The part is active in production with ROHS3 compliance and includes epoxy sealed terminals for enhanced environmental protection. Contact timing is specified as Non-Shorting (BBM), providing defined switching behavior.

CW Industries GS-113-0045 is an alternative substitute with equivalent electrical performance. The actuator length is 0.05mm shorter (4.75mm versus 4.80mm), and the operating temperature range is extended to -10°C to 104°C. This part retains PC Pin termination, matching the original SLA2201 mounting interface. The part is active in production with ROHS3 compliance. Operating force is not specified in available documentation.

Both substitutes are ROHS3 compliant and active in production, providing long-term availability compared to the obsolete SLA2201.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1825087-1 be used as a direct replacement for the SLA2201?

A: Electrical and mechanical compatibility is confirmed. The primary difference is termination style: the 1825087-1 uses Solder Turret termination instead of PC Pin. PCB footprint modification is required. All electrical ratings, actuator dimensions, and operating temperature ranges are identical.

Q: What is the difference between the two substitute parts?

A: The TE Connectivity 1825087-1 and CW Industries GS-113-0045 both meet electrical requirements. The 1825087-1 uses Solder Turret termination with Non-Shorting contact timing. The GS-113-0045 retains PC Pin termination matching the original SLA2201. The GS-113-0045 has a 0.05mm shorter actuator and extended temperature range to 104°C.

Q: Is the 0.05mm actuator length difference between the SLA2201 and GS-113-0045 significant?

A: The actuator length difference of 0.05mm (4.80mm versus 4.75mm) is within typical mechanical tolerance for slide switch applications. Compatibility depends on specific panel cutout and actuator clearance specifications in the end application.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the TE Connectivity 1825087-1 and CW Industries GS-113-0045 are ROHS3 compliant, matching the compliance status of the original SLA2201.

Q: Which substitute should be selected for new designs?

A: Selection depends on termination requirements. For PC Pin termination compatibility with existing PCB layouts, the CW Industries GS-113-0045 is recommended. For applications requiring solder turret termination and non-shorting contact timing, the TE Connectivity 1825087-1 is appropriate.
