SLB12814 Equivalent & Substitute Parts

Part Overview

The SLB12814 is a slide switch manufactured by APEM Inc., configured as a Single Pole Double Throw (SPDT) switch with On-On functionality. This component is rated for 300mA at 125V AC and 30V DC, featuring through-hole mounting with PC pin termination and epoxy sealed terminals. The product 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 of the SLB12814 is based on the following critical parameters that must be maintained or exceeded:

• Circuit Configuration: SPDT topology required for functional equivalence
• Switch Function: On-On operation for proper circuit behavior
• Mounting Type: Through-hole with PC pin termination for PCB compatibility
• Voltage and Current Ratings: Substitute must support the application's electrical requirements
• Operating Temperature Range: -20°C to 85°C minimum
• Compliance: RoHS3 compliance required for regulatory alignment

The substitute part 1825257-2 (TE Connectivity ALCOSWITCH Switches) meets the core functional requirements of SPDT configuration and On-On switching with through-hole PC pin mounting. However, electrical ratings differ and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 1825257-2 provides functional SPDT switching capability with active product status and ROHS3 compliance. This substitute is suitable for applications where the electrical requirements do not exceed 0.4VA at 20V AC/DC. Applications requiring the full 300mA at 125V AC or 30V DC ratings of the original SLB12814 cannot use this substitute without circuit redesign or voltage/current limiting measures.

The substitute offers improved electrical life (15,000 cycles versus 10,000 cycles) and is currently in active production, ensuring long-term availability. Both components maintain identical operating temperature ranges and through-hole PC pin mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1825257-2 directly replace the SLB12814 in all applications?

A: Direct replacement is limited to applications where the circuit operates at or below 0.4VA and 20V AC/DC. Applications requiring higher voltage or current ratings require circuit evaluation and potential redesign.

Q: What are the key differences between these two switches?

A: The primary differences are electrical ratings (current and voltage capacity) and product status. The SLB12814 is rated for higher power (300mA at 125V AC), while the 1825257-2 is rated for lower power (0.4VA at 20V AC/DC). The 1825257-2 is currently in active production, whereas the SLB12814 is obsolete.

Q: Are both switches RoHS3 compliant?

A: Yes, both the SLB12814 and 1825257-2 are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.

Q: Do both switches have the same mounting footprint?

A: Both switches use through-hole mounting with PC pin termination. Physical dimensions such as actuator length (4.00mm for SLB12814 versus 5.00mm for 1825257-2) and switch travel (3.20mm versus 2.00mm) differ and must be verified against PCB layout requirements.

Q: What is the mechanical life expectancy of these switches?

A: The SLB12814 does not specify mechanical life. The 1825257-2 specifies 15,000 mechanical cycles. Both components specify electrical life ratings (10,000 and 15,000 cycles respectively).
