APEM Inc. SLB22804 Equivalent & Substitute Parts

Part Overview

The APEM Inc. SLB22804 is a slide switch with DPDT (Double Pole Double Throw) configuration rated for 300mA at 125V AC and 30V DC. This component features through-hole mounting with PC pin termination and epoxy sealed terminals. The part is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLB22804 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Circuit configuration (DPDT required)
• Switch function (On-On operation)
• Current rating capability (minimum 300mA)
• Voltage rating (minimum 125V AC)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Operating temperature range (-20°C to 85°C)
• Contact finish (Silver preferred for compatibility)
• RoHS compliance status

Two substitute parts meet these criteria: TE Connectivity ALCOSWITCH Switches part numbers 1825289-1 and 1825261-2. The 1825289-1 provides direct electrical equivalence with matching current and voltage ratings. The 1825261-2 operates at reduced voltage and current levels but maintains DPDT configuration and through-hole mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity ALCOSWITCH Switches 1825289-1 is the primary substitute for the SLB22804. This part maintains electrical equivalence with 300mA current rating at 125V AC, identical mounting and termination specifications, and matching operating temperature range. The 1825289-1 is currently in active production status with ROHS3 compliance and extended electrical life rating of 15,000 cycles compared to the original 10,000 cycles.

The TE Connectivity ALCOSWITCH Switches 1825261-2 serves as a secondary substitute option for applications operating at reduced voltage and current levels (20V AC/DC, 0.4VA). This part is suitable only for circuits where the lower electrical ratings are acceptable. The gold contact finish on the 1825261-2 differs from the silver finish of the original part.

Both substitute parts are manufactured by TE Connectivity ALCOSWITCH Switches, carry active product status, and maintain ROHS3 compliance and through-hole PC pin termination compatibility with the obsolete SLB22804.

Frequently Asked Questions (FAQ)

Q: Can the 1825289-1 be used as a direct replacement for the SLB22804?

A: Yes. The 1825289-1 matches the critical electrical parameters: 300mA current rating, 125V AC voltage rating, DPDT configuration, On-On switch function, through-hole mounting, and PC pin termination. Operating temperature range and RoHS compliance are identical.

Q: What are the limitations of using the 1825261-2 as a substitute?

A: The 1825261-2 operates at significantly lower voltage (20V AC/DC) and current (0.4VA) ratings compared to the SLB22804 (125V AC, 30V DC, 300mA). This part is suitable only for low-voltage applications. The contact finish is gold rather than silver.

Q: Are there mechanical differences between the substitute parts and the original?

A: Yes. The 1825289-1 has an actuator length of 4.50mm and switch travel of 4.00mm, compared to the SLB22804 specifications of 4.00mm actuator length and 3.20mm switch travel. The 1825261-2 has reduced actuator length (2.30mm) and switch travel (2.00mm). Physical dimensions should be verified for PCB layout compatibility.

Q: Do the substitute parts have the same contact material?

A: The SLB22804 uses silver contact finish. The 1825289-1 also uses silver contact finish. The 1825261-2 uses gold contact finish, which may affect compatibility in specific circuit applications.

Q: What is the difference in operating force between these parts?

A: The SLB22804 has an operating force of 220gf. Both substitute parts (1825289-1 and 1825261-2) have an operating force of 600gf, requiring greater actuation force.

Q: Are all parts RoHS compliant?

A: Yes. The SLB22804, 1825289-1, and 1825261-2 are all ROHS3 compliant.
