Equivalent & Substitute Parts for Honeywell 11SM23-H2

Part Overview

The Honeywell 11SM23-H2 is a snap action switch with Single Pole Double Throw (SPDT) configuration, rated for 1A at 125V AC and 30V DC. This through-hole mounted switch features a round pin plunger actuator and is designed for on-momentary switching applications. The part is currently active in production with full RoHS compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct functional replacement in circuit designs, subject to application-specific current and voltage requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 11SM23-H2 is determined by the following critical parameters:

Electrical Compatibility:

• Circuit configuration must be SPDT
• Switch function must be On-Mom
• Voltage rating must meet or exceed 125V AC requirement
• Current rating must meet or exceed 1A requirement

Mechanical Compatibility:

• Actuator type must be Round (Pin Plunger)
• Mounting type must be Through Hole
• Termination style must be PC Pin
• Operating position must be 0.330" (8.4mm)

Environmental & Compliance:

• Operating temperature range must encompass application requirements
• RoHS compliance status must be acceptable for end-use market
• Mechanical life must support application cycle requirements

The ZF Electronics DB2CC1AA meets these core substitution criteria with the following considerations: it provides higher current capacity (10A AC versus 1A AC/DC), maintains identical voltage rating (125V AC), shares identical mechanical interface parameters, and maintains equivalent mechanical life rating.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (11SM23-H2): The Honeywell 11SM23-H2 is the specified component for applications requiring 1A current capacity at 125V AC or 30V DC with operating temperatures down to -55°C. This part maintains active production status with full RoHS compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute Part Selection (DB2CC1AA): The ZF Electronics DB2CC1AA is electrically and mechanically compatible for applications where current requirements do not exceed 10A AC at 125V AC. This substitute provides higher current capacity margin and includes IP50 dust protection. The operating temperature range (-40°C to 120°C) is narrower than the primary part; applications requiring operation below -40°C must use the 11SM23-H2. The DB2CC1AA maintains ROHS3 compliance and equivalent mechanical life rating.

Compliance Considerations: Both parts carry equivalent RoHS compliance status suitable for EU market applications. The DB2CC1AA includes REACH Unaffected designation. Both parts share identical ECCN (EAR99) and HTSUS (8536.50.7000) classifications.

Frequently Asked Questions (FAQ)

Q: Can the DB2CC1AA replace the 11SM23-H2 in all applications?

A: The DB2CC1AA is mechanically and electrically compatible for SPDT on-momentary switching at 125V AC. However, applications requiring DC voltage operation must use the 11SM23-H2, as the DB2CC1AA DC rating is not specified. Applications requiring operation below -40°C must use the 11SM23-H2 due to its extended temperature range (-55°C to 125°C).

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

A: The 11SM23-H2 requires 141gf operating force, while the DB2CC1AA requires 250gf. This difference affects actuator design and mechanical interface considerations. Applications with force-sensitive actuator mechanisms must account for this parameter difference.

Q: Are both parts through-hole mounted with identical pin configurations?

A: Yes. Both parts feature through-hole mounting with PC pin termination style and identical operating position of 0.330" (8.4mm). PCB layout and mechanical mounting are directly compatible.

Q: What is the significance of the IP50 rating on the DB2CC1AA?

A: The DB2CC1AA includes IP50 dust protection, indicating sealed design against dust ingress. The 11SM23-H2 ingress protection rating is not specified. Applications in dusty or contaminated environments may benefit from the DB2CC1AA's sealed design.

Q: Can I use the DB2CC1AA in a 1A circuit designed for the 11SM23-H2?

A: Yes. The DB2CC1AA is rated for 10A AC at 125V, which exceeds the 1A requirement. Current capacity is a maximum rating; operating at lower current levels is acceptable. Verify that DC voltage operation is not required, as the DB2CC1AA DC rating is not specified.

Q: What is the mechanical life expectancy for both parts?

A: Both the 11SM23-H2 and DB2CC1AA are rated for 10,000,000 mechanical cycles, providing equivalent durability for high-cycle applications.
