Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLB2281R5 is determined by the following critical parameters:

• Circuit Configuration: DPDT topology is mandatory for functional equivalence
• Switch Function: On-On operation must be maintained
• Current Rating: Minimum 300mA capacity required
• Voltage Rating - AC: Minimum 125V AC rating required
• Mounting Type: Through hole, right-angle configuration required for PCB compatibility
• Termination Style: PC pin termination required for board-level integration
• Actuator Length: 5.00mm nominal dimension for mechanical fit
• Contact Finish: Silver finish for electrical performance consistency

The TE Connectivity ALCOSWITCH 1825166-1 meets all mandatory substitution criteria across these parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity ALCOSWITCH 1825166-1

The 1825166-1 is functionally equivalent to the SLB2281R5 across all critical electrical and mechanical parameters. Both components share identical DPDT configuration, 300mA current rating, 125V AC voltage rating, through-hole right-angle mounting, PC pin termination, and 5.00mm actuator length.

Compliance Considerations:

The SLB2281R5 carries ROHS3 compliance certification, while the 1825166-1 status is listed as not applicable. For applications requiring RoHS compliance documentation, the original SLB2281R5 specification should be retained if available from inventory. The 1825166-1 is suitable for applications without explicit RoHS requirements.

Temperature Range Variance:

The 1825166-1 operates within -10°C to 60°C, which is narrower than the SLB2281R5 range of -20°C to 85°C. Applications requiring operation below -10°C or above 60°C must retain the SLB2281R5 or identify alternative sources.

Product Status:

The SLB2281R5 is obsolete. The 1825166-1 is active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 1825166-1 directly replace the SLB2281R5 in all applications?

A: The 1825166-1 is electrically and mechanically compatible with the SLB2281R5 for standard operating conditions. However, applications operating outside the -10°C to 60°C range or requiring RoHS3 compliance documentation must evaluate the temperature and compliance requirements against the 1825166-1 specifications.

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

A: The SLB2281R5 has 3.20mm switch travel, while the 1825166-1 has 2.50mm switch travel. Both are within typical slide switch specifications and should not affect functional performance in standard applications.

Q: Are the operating forces equivalent?

A: The SLB2281R5 requires 220gf operating force, while the 1825166-1 requires 250gf. This 30gf difference is minor and should not impact user experience or system operation in typical applications.

Q: What is the contact timing difference noted for the 1825166-1?

A: The 1825166-1 specifies shorting (MBB - Make Before Break) contact timing. The SLB2281R5 contact timing is not specified. MBB timing ensures continuity is maintained during switching transitions, which is beneficial for most applications.

Q: Are both components suitable for through-hole PCB assembly?

A: Yes. Both the SLB2281R5 and 1825166-1 feature through-hole, right-angle mounting with PC pin termination, making them compatible with standard PCB assembly processes.

Q: What inventory status should influence component selection?

A: The SLB2281R5 has 714 pieces in stock (obsolete status), while the 1825166-1 has 953 pieces available (active production). For new designs or long-term production, the 1825166-1 is recommended due to active product status and sustained availability.
