Honeywell 12CX5 Snap Action Switch SPDT x2 Equivalent & Substitute Parts

Part Overview

The Honeywell 12CX5 is a dual SPDT snap action switch rated for 20A AC at 120V, designed for chassis mount applications with explosion-proof construction and IP66 ingress protection. This component is classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing system support and new design implementations. The 12CX5 operates with side rotary actuation and screw terminal connections, serving applications requiring reliable switching with high environmental resistance.

Substitute Part Grouping Explanation

Substitution of the Honeywell 12CX5 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Dual SPDT circuit configuration (SPDT x 2)
• 20A AC current rating at 120V AC
• 500mA DC current rating at 125V DC
• Momentary (On-Mom) switch function

Mechanical & Environmental Equivalence Criteria:

• Side rotary actuator without lever
• Chassis mount configuration
• Screw terminal connections
• IP66 ingress protection rating
• Explosion-proof construction
• Operating temperature range -25°C to 85°C

Compliance Equivalence Criteria:

• RoHS compliant status
• Identical ECCN and HTSUS classifications

The substitute part 12CX2 meets all these criteria with identical electrical, mechanical, and environmental specifications. The primary distinction is product status: 12CX5 is obsolete while 12CX2 is active production.

Parameter Comparison

Engineering Selection Recommendations

The Honeywell 12CX2 is the direct functional equivalent for the obsolete 12CX5 snap action switch. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the CX series and share identical electrical ratings, mechanical specifications, and environmental certifications.

For Obsolescence Mitigation: The 12CX2 is classified as active production status, ensuring continued availability and supply chain reliability. This addresses the primary limitation of the 12CX5, which is no longer manufactured.

For Compliance Continuity: Both parts maintain identical RoHS compliance status and carry the same ECCN (EAR99) and HTSUS (8536.50.9055) classifications, ensuring regulatory and trade compliance equivalence.

For System Integration: Electrical and mechanical parameters are fully identical across all switching characteristics, actuator specifications, and environmental ratings. Direct substitution is supported without circuit redesign or mechanical modification.

Packaging Consideration: The 12CX2 is supplied in bulk packaging, whereas the 12CX5 was supplied in standard packaging. Procurement quantities should account for this packaging difference.

Frequently Asked Questions (FAQ)

Q: Can the 12CX2 directly replace the 12CX5 in existing applications?

A: Yes. The 12CX2 is electrically and mechanically identical to the 12CX5 across all specified parameters. Direct substitution is supported without circuit modification or mechanical redesign.

Q: What is the primary reason for substitution?

A: The 12CX5 is classified as obsolete and is no longer in active production. The 12CX2 is the active production equivalent with identical specifications.

Q: Are the electrical ratings identical?

A: Yes. Both parts are rated for 20A AC at 120V and 500mA DC at 125V with dual SPDT momentary switching function.

Q: Do both parts meet the same environmental specifications?

A: Yes. Both parts feature IP66 ingress protection, explosion-proof construction, and operate across the identical temperature range of -25°C to 85°C.

Q: Is RoHS compliance maintained with the substitute?

A: Yes. The 12CX2 maintains RoHS compliant status identical to the 12CX5.

Q: What is the difference between the two parts?

A: The primary differences are product status (12CX5 is obsolete; 12CX2 is active) and packaging format (12CX2 is supplied in bulk packaging). All electrical, mechanical, and environmental specifications are identical.

Q: Are the actuator and mounting specifications the same?

A: Yes. Both parts feature side rotary actuation without lever, chassis mount configuration, and screw terminal connections.

Q: Can the 12CX2 be used in new designs?

A: Yes. The 12CX2 is recommended for new designs as it is in active production with full availability and supply chain support.
