ASF22GL Equivalent & Substitute Parts

Part Overview

The ASF22GL is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a DPDT (Double Pole Double Throw) surface mount component with a 0.4VA current rating at 20V. This switch features a screwdriver slot actuator, gold-plated copper alloy contacts, and gull wing termination for surface mount applications. The ASF22GL is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing design requirements and procurement needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASF22GL is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish valid substitutes:

Electrical Equivalence Requirements:

• DPDT circuit configuration
• Shorting (MBB) contact timing
• On-On switch function
• 0.4VA current rating (AC/DC)
• 20V AC and DC voltage ratings
• Copper alloy contacts with gold finish

Mechanical Equivalence Requirements:

• 2.79mm switch travel
• 950gf operating force
• 15,000 cycle mechanical and electrical life
• -40°C to 80°C operating temperature range
• Polyamide (PA46) nylon 4/6 actuator material

Substitutes are grouped into two categories:

1. Direct Electrical and Mechanical Equivalent (Surface Mount): Part 1825011-5 maintains identical electrical specifications and surface mount termination (gull wing), with the distinction of active product status and improved compliance certifications.

2. Functional Equivalent with Mounting Variation (Through Hole): Part ASE22G provides electrical equivalence but differs in mounting technology (through hole with PC pin termination instead of surface mount with gull wing termination), representing a design-level substitution requiring PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No PCB Modification Required):

Part 1825011-5 is the primary substitute for ASF22GL. This part maintains identical electrical specifications, mechanical performance, and surface mount form factor. The 1825011-5 offers the additional advantage of active product status, ensuring continued availability and supply chain stability. The part achieves ROHS3 compliance and REACH unaffected status, providing superior regulatory positioning compared to the obsolete ASF22GL. Selection of 1825011-5 is appropriate for applications requiring immediate substitution without design revision.

For Design Flexibility (PCB Modification Required):

Part ASE22G provides functional electrical equivalence but requires PCB layout modification due to through-hole mounting technology and PC pin termination. This part is suitable for applications where PCB redesign is feasible and through-hole mounting is preferred for mechanical robustness or assembly process compatibility. The ASE22G maintains active product status but does not achieve RoHS3 compliance.

Compliance Considerations:

The ASF22GL is RoHS non-compliant with vendor-undefined REACH status. The 1825011-5 substitute achieves ROHS3 compliance and REACH unaffected status, making it the preferred choice for applications subject to environmental regulations or customer compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can 1825011-5 be used as a direct replacement for ASF22GL without PCB modification?

A: Yes. The 1825011-5 maintains identical electrical specifications (DPDT, 0.4VA, 20V), mechanical performance (15,000 cycles, 950gf operating force), and surface mount termination (gull wing). No PCB layout modification is required for substitution.

Q: What is the primary difference between 1825011-5 and ASF22GL?

A: The 1825011-5 is an active product with ROHS3 compliance and REACH unaffected status, whereas the ASF22GL is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Why is ASE22G listed as a substitute if it requires PCB modification?

A: The ASE22G provides functional electrical equivalence across all critical parameters (DPDT circuit, 0.4VA current, 20V voltage, 15,000 cycle life). However, it uses through-hole mounting with PC pin termination instead of surface mount gull wing termination. This part is suitable for applications where PCB redesign is acceptable or preferred.

Q: What packaging differences exist between the substitute parts?

A: The ASF22GL is supplied in tape seal packaging. The 1825011-5 is supplied in tube packaging. The ASE22G is supplied in bulk packaging. Packaging selection should align with assembly process requirements and inventory management practices.

Q: Are there any electrical performance differences between the three parts?

A: No. All three parts maintain identical electrical specifications: DPDT configuration, shorting (MBB) contact timing, on-on switch function, 0.4VA current rating, 20V AC/DC voltage rating, copper alloy gold-plated contacts, and 15,000 cycle electrical life.

Q: Which substitute part should be selected for new designs?

A: The 1825011-5 is the recommended substitute for new designs. It provides direct form-factor compatibility with the ASF22GL, active product status ensuring long-term availability, and superior compliance certifications (ROHS3 compliant, REACH unaffected).

Q: Can ASE22G be used in applications originally designed for ASF22GL?

A: The ASE22G provides electrical and mechanical equivalence but requires PCB layout modification due to different mounting technology (through-hole versus surface mount). Substitution is feasible only if PCB redesign is acceptable within project constraints.

Q: What is the operating force difference between these parts?

A: All three parts have identical operating force specifications of 950gf. No performance difference exists in actuator force requirements.

Q: Are there temperature rating differences between the substitute parts?

A: No. All three parts maintain identical operating temperature range of -40°C to 80°C.
