ASF42 Equivalent & Substitute Parts

Part Overview

The ASF42 is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, classified as a 4PDT (four-pole double-throw) through-hole component. This switch is rated for 300mA AC at 115V and features a screwdriver slot actuator with shorting contact timing. The ASF42 maintains active product status and is suitable for applications requiring reliable switching in industrial and commercial environments.

Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable, while maintaining identical electrical and mechanical performance specifications.

Engineering Selection Recommendations

Both the ASF42 and 2-1825011-1 are functionally equivalent 4PDT slide switches from TE Connectivity ALCOSWITCH Switches with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

Compliance Considerations: The 2-1825011-1 carries ROHS3 compliance certification and REACH Unaffected status, providing documented regulatory compliance for applications subject to these requirements. The ASF42 does not carry these certifications.

Packaging Considerations: The ASF42 is supplied in standard packaging, while the 2-1825011-1 is supplied in tube packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Availability: Both parts maintain active product status with current inventory. The 2-1825011-1 has 1637 units in stock, while the ASF42 has 1185 units in stock.

For applications requiring regulatory compliance documentation, the 2-1825011-1 is the appropriate selection. For applications without specific compliance requirements, either part provides equivalent performance.

Frequently Asked Questions (FAQ)

Q: Can the 2-1825011-1 be used as a direct replacement for the ASF42?
