ASF22RG Equivalent & Substitute Parts

Part Overview

The ASF22RG is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Double Pole Double Throw (DPDT) switch with a rated capacity of 0.4VA at 20V. This component features a through-hole, right-angle mounting configuration with a screwdriver slot actuator and gold-plated copper alloy contacts. The ASF22RG maintains Active product status with 1,112 units currently in stock.

Substitute parts become necessary when the primary component reaches end-of-life status, inventory depletion, or when design requirements necessitate alternative configurations within the same electrical and mechanical parameter range. The ASF22RG series accommodates direct substitution with compatible variants that maintain identical electrical ratings and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASF22RG is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Circuit configuration must be DPDT
• Contact timing must be Shorting (MBB)
• Switch function must be On-On
• Current rating must be 0.4VA (AC/DC)
• Voltage ratings must be 20V (both AC and DC)

Mechanical Equivalence Requirements:

• Actuator type must be Screwdriver Slot
• Actuator length must be Flush
• Contact material must be Copper Alloy
• Contact finish must be Gold
• Mounting type must be Through Hole, Right Angle
• Termination style must be PC Pin

Performance Equivalence Requirements:

• Operating temperature range must be -40°C to 80°C
• Switch travel must be 2.79mm
• Mechanical life must be 15,000 cycles
• Electrical life must be 15,000 cycles
• Operating force must be 950gf

Parts meeting all specified parameters are classified as direct substitutes. The part 1825011-4 satisfies all electrical, mechanical, and performance requirements for direct substitution with the ASF22RG.

Engineering Selection Recommendations

ASF22RG (Primary Selection)

The ASF22RG is the recommended component for new designs and applications requiring active product support. This part maintains Active product status with confirmed inventory availability of 1,112 units. The ASF22RG provides continuity of supply and manufacturer support for the specified electrical and mechanical requirements.

1825011-4 (Substitute Selection)

The part 1825011-4 is electrically and mechanically equivalent to the ASF22RG across all specified parameters. However, this component carries Obsolete product status, indicating discontinued manufacturing and limited long-term availability. Current inventory stands at 863 units. Selection of 1825011-4 is appropriate only when ASF22RG supply is unavailable and immediate component procurement is required. The Obsolete status indicates this part should not be selected for new designs or applications with extended production timelines.

Both parts are manufactured by TE Connectivity ALCOSWITCH Switches and share identical electrical ratings, mechanical configurations, and performance characteristics. The choice between these parts is determined by product lifecycle status and supply chain requirements rather than functional differences.

Frequently Asked Questions (FAQ)

Q: Can 1825011-4 be used as a direct replacement for ASF22RG in existing designs?

A: Yes. The 1825011-4 is electrically and mechanically equivalent to the ASF22RG. All critical parameters including circuit configuration (DPDT), current rating (0.4VA), voltage rating (20V AC/DC), actuator type (Screwdriver Slot), mounting configuration (Through Hole, Right Angle), and performance specifications (15,000 cycle life) are identical. Direct substitution is permissible from a functional standpoint.

Q: Why is 1825011-4 listed as Obsolete if it is equivalent to ASF22RG?

A: Product status reflects manufacturing and supply availability rather than functional capability. The Obsolete designation indicates that 1825011-4 is no longer in active production. While the part remains electrically and mechanically equivalent, its Obsolete status means inventory is finite and manufacturer support is limited. For applications requiring long-term component availability, ASF22RG is the appropriate selection.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by equivalence across electrical parameters (DPDT circuit, 0.4VA current rating, 20V voltage rating, Shorting contact timing, On-On function), mechanical parameters (Screwdriver Slot actuator, Flush length, Copper Alloy contacts with Gold finish, Through Hole Right Angle mounting, PC Pin termination), and performance specifications (2.79mm travel, 15,000 cycle mechanical and electrical life, 950gf operating force, -40°C to 80°C temperature range).

Q: Are there any compliance or certification differences between ASF22RG and 1825011-4?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9050) classifications. RoHS Status is Not Applicable for both components. The 1825011-4 specifies Moisture Sensitivity Level (MSL) of 1 (Unlimited), while ASF22RG lists MSL as Not Applicable. REACH Status is Vendor Undefined for both parts.

Q: What is the difference in current inventory between these parts?

A: ASF22RG has 1,112 units in stock, while 1825011-4 has 863 units available. The higher inventory level for ASF22RG, combined with its Active product status, makes it the preferred selection for applications with flexible procurement timelines.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts feature identical Through Hole, Right Angle mounting configurations with PC Pin termination. PCB footprints and mounting hole patterns are equivalent. No design modifications are required for substitution.
