Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AVT32023 are grouped based on the following substitution criteria:

Primary Matching Parameters:

• Circuit configuration: SPDT (Single Pole Double Throw)
• Switch function: On-Mom (momentary operation)
• Actuator type: Round pin plunger
• Mounting type: Chassis mount
• Termination style: Solder connection (lug or turret)

Electrical Rating Compatibility: Substitutes are acceptable when they meet or exceed the voltage and current requirements of the application. The AVT32023 operates at 3A/125V AC and 30V DC. Substitute parts with higher current ratings (4A, 5A) or higher AC voltage ratings (250V) are electrically compatible for applications requiring the AVT32023 specifications.

Mechanical Compatibility: All substitute parts maintain the same operating position (0.330" / 8.4mm), ensuring mechanical interchangeability in chassis-mounted applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents (3A Rating): The AVT32023 operates at 3A/125V AC. Among the listed substitutes, 11SM703-T provides the closest electrical match with 4A AC rating at 250V AC, exceeding the original specification and suitable for direct replacement in 125V AC applications. This part maintains Active product status and RoHS compliance.

Higher Current Capacity Substitutes (5A Rating): Parts 1SM1-T, 22SM22-T, 22SM426-T, and 22SM82-T all provide 5A ratings at 250V AC, offering increased current capacity and voltage headroom. These are suitable for applications where the AVT32023 is specified but higher electrical margins are acceptable. All maintain Active status and RoHS compliance.

Lower Current Substitutes: 11SM76-T (1A) and 11SM1777-T (100mA) are electrically limited compared to the AVT32023 and are suitable only for applications with reduced current requirements.

Compliance and Availability: All substitute parts are Active status with RoHS compliance. Honeywell Sensing and Productivity Solutions parts offer extended operating temperature ranges (-55°C to 125°C) compared to the AVT32023 (-25°C to 85°C), providing thermal margin in demanding environments.

Frequently Asked Questions (FAQ)

Q: Can I use a Honeywell 11SM703-T to replace an AVT32023? A: Yes. The 11SM703-T maintains SPDT circuit configuration, round pin plunger actuator, and chassis mount design. Its 4A/250V AC rating exceeds the AVT32023 specification of 3A/125V AC, making it electrically compatible for direct substitution.

Q: What is the difference between solder lug and solder turret termination? A: Both are solder-based termination methods suitable for PCB or chassis mounting. Solder lug termination (AVT32023) uses a flat tab, while solder turret termination (Honeywell parts) uses a cylindrical post. Both are compatible with standard solder connection processes.

Q: Are the 5A-rated Honeywell parts (1SM1-T, 22SM22-T, 22SM426-T, 22SM82-T) interchangeable? A: All four parts share identical electrical ratings (5A/250V AC/DC) and mechanical specifications (round pin plunger, chassis mount, 0.330" operating position). They differ in operating force and mechanical life characteristics. Selection depends on application-specific force requirements and cycle life expectations.

Q: Why does 11SM1777-T have a 100mA rating when the AVT32023 is 3A? A: The 11SM1777-T is a lower-current variant within the Honeywell SM series. It is not suitable as a direct substitute for the AVT32023 in applications requiring 3A capacity, but may be used in lower-current applications where the AVT32023 is over-specified.

Q: What packaging options are available for these substitutes? A: AVT32023 is supplied in Bulk packaging. Honeywell substitutes are available in Bulk (11SM1777-T, 11SM703-T, 22SM22-T, 22SM426-T, 22SM82-T) or Tray (1SM1-T) packaging. Packaging selection does not affect electrical or mechanical compatibility.

Q: Do all substitutes meet RoHS requirements? A: Yes. The AVT32023 is RoHS3 compliant. All listed Honeywell substitutes are RoHS compliant, meeting regulatory requirements for lead-free and restricted substance compliance.
