ASF22 Equivalent & Substitute Parts

Part Overview

The ASF22 is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Double Pole Double Throw (DPDT) switch with a 300mA AC current rating at 115V. This through-hole mounted component features a screwdriver slot actuator and is designed for On-On switching applications with shorting contact timing. The ASF22 is classified as an active product with 973 units currently in stock.

Identifying equivalent and substitute parts for the ASF22 becomes necessary when addressing supply chain constraints, design revisions requiring updated compliance certifications, or inventory optimization across manufacturing operations. Substitute parts must maintain identical electrical performance and mechanical compatibility to ensure direct replacement without circuit redesign.

• Contact timing must be Shorting (MBB)
• Switch function must be On-On

Mechanical Parameters:

• Mounting type must be Through Hole
• Termination style must be PC Pin
• Actuator type must be Screwdriver Slot
• Switch travel must be 2.79mm
• Operating temperature range must encompass -40°C to 80°C
• Mechanical and electrical life must be 15,000 cycles minimum

Manufacturer Consistency: All substitute parts are sourced from TE Connectivity ALCOSWITCH Switches to ensure design consistency and quality standards alignment.

Parameter Comparison

Engineering Selection Recommendations

The ASF22 and 1825011-1 are electrically and mechanically equivalent components. All functional parameters, including circuit configuration, current and voltage ratings, actuator specifications, and lifecycle ratings, are identical between the two parts.

The primary distinction between these components is their regulatory compliance status. The 1825011-1 carries ROHS3 compliance certification and REACH Unaffected status, whereas the ASF22 is classified as RoHS non-compliant with vendor-undefined REACH status. For applications subject to RoHS3 or REACH regulatory requirements, the 1825011-1 is the appropriate selection. For applications without such regulatory constraints, either part satisfies the electrical and mechanical requirements.

Both components maintain active product status with TE Connectivity ALCOSWITCH Switches, ensuring continued availability and manufacturing support. The 1825011-1 currently maintains higher inventory levels (2097 units) compared to the ASF22 (973 units).

Frequently Asked Questions (FAQ)

Q: Can the 1825011-1 be used as a direct replacement for the ASF22 in existing designs?

A: Yes. The 1825011-1 is electrically and mechanically equivalent to the ASF22. All electrical parameters (DPDT configuration, 300mA AC, 115V AC, shorting contact timing, On-On function) and mechanical parameters (through-hole mounting, PC pin termination, screwdriver slot actuator, 2.79mm travel, 15,000 cycle life) are identical. Direct substitution in PCB layouts and circuit designs is supported without modification.

Q: What is the significance of the RoHS3 compliance difference?

A: RoHS3 compliance indicates that the 1825011-1 meets the Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials in electrical and electronic equipment. The ASF22 does not carry this certification. For applications subject to RoHS3 regulatory requirements or customer specifications mandating RoHS3 compliance, the 1825011-1 must be selected. For applications without such requirements, both parts are functionally equivalent.

Q: Are there packaging differences between these parts?

A: No. Both the ASF22 and 1825011-1 are supplied in tube packaging, maintaining identical handling and storage requirements.

Q: What is the operating force specification, and does it affect substitution?

A: Both parts specify an operating force of 950gf (gram-force), indicating the force required to actuate the switch. This parameter is identical between the ASF22 and 1825011-1, confirming mechanical equivalence and ensuring consistent user interface behavior in applications.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both the ASF22 and 1825011-1 support the identical operating temperature range of -40°C to 80°C. Selection between these parts for temperature-dependent applications is not differentiated by thermal specifications.

Q: What does the REACH Unaffected status mean for the 1825011-1?

A: REACH Unaffected status indicates that the 1825011-1 is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory requirements. The ASF22 carries vendor-undefined REACH status. For applications requiring documented REACH compliance status, the 1825011-1 provides explicit regulatory clarity.
