ASF22L Equivalent & Substitute Parts

Part Overview

The ASF22L 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 surface mount component features a screwdriver slot actuator, copper alloy contacts with silver finish, and gull wing termination. The ASF22L is classified as obsolete, making identification of equivalent and substitute parts essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASF22L is determined by electrical and mechanical parameter equivalence across the following critical specifications:

Electrical Parameters: Circuit configuration (DPDT), current rating (300mA AC), voltage rating (115V AC), contact timing (Shorting MBB), and switch function (On-On) must remain constant across all substitutes.

Mechanical Parameters: Contact material (Copper Alloy), contact finish (Silver), switch travel (2.79mm), mechanical life (15,000 cycles), electrical life (15,000 cycles), and operating force (950gf) must be identical.

Environmental Parameters: Operating temperature range (-40°C to 80°C) and actuator material (Polyamide PA46, Nylon 4/6) must be maintained.

The substitute parts identified for ASF22L differ in mounting technology and product status but maintain full electrical and mechanical equivalence. Part 1825011-7 represents a direct functional equivalent with surface mount gull wing termination in active production status. Part ASE22 provides functional equivalence with through-hole mounting technology, representing a design alternative for applications requiring different PCB integration methods.

Parameter Comparison

Engineering Selection Recommendations

For Direct Surface Mount Replacement: Part 1825011-7 is the primary substitute for ASF22L. Both components share identical electrical specifications, mechanical characteristics, and surface mount gull wing termination. Part 1825011-7 is in active production status with ROHS3 compliance certification, providing supply chain continuity and regulatory alignment. This part maintains the same PCB footprint and assembly process compatibility as the original ASF22L.

For Through-Hole Design Integration: Part ASE22 provides functional electrical and mechanical equivalence with alternative mounting technology. This part is suitable for applications requiring through-hole PCB integration rather than surface mount assembly. ASE22 is in active production status with ROHS3 compliance. Design implementation requires PCB layout modification to accommodate PC pin termination instead of gull wing termination.

Compliance Considerations: Both substitute parts carry ROHS3 compliance certification, whereas the obsolete ASF22L does not have applicable RoHS status. For applications subject to RoHS regulatory requirements, either substitute part satisfies compliance obligations.

Frequently Asked Questions (FAQ)

Q: Can 1825011-7 be used as a direct replacement for ASF22L without PCB modification?

A: Yes. Part 1825011-7 maintains identical electrical specifications, mechanical characteristics, and surface mount gull wing termination. No PCB layout modification is required for direct substitution.

Q: What is the primary difference between 1825011-7 and ASE22?

A: The primary difference is mounting technology. Part 1825011-7 uses surface mount gull wing termination, while ASE22 uses through-hole PC pin termination. Both parts are electrically and mechanically equivalent. Selection depends on PCB design requirements.

Q: Is ASE22 suitable for applications originally designed for ASF22L?

A: ASE22 provides electrical and mechanical equivalence but requires PCB redesign due to different termination style and mounting type. Through-hole mounting is not compatible with surface mount PCB layouts designed for ASF22L.

Q: What is the inventory status for substitute parts?

A: Part 1825011-7 has 1,640 pieces in stock. Part ASE22 has 846 pieces in stock. Both parts are in active production.

Q: Are there compliance differences between ASF22L and its substitutes?

A: Yes. ASF22L has no applicable RoHS status. Both substitute parts (1825011-7 and ASE22) are ROHS3 compliant. For applications requiring RoHS compliance, substitute parts satisfy regulatory requirements.

Q: What packaging options are available for substitute parts?

A: Part 1825011-7 is supplied in tube packaging. Part ASE22 is supplied in bulk packaging. Packaging selection may affect procurement and assembly process requirements.
