Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLM22031 is based on electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Coil voltage: 110–120VAC (identical)
• Contact current rating: 20A (identical)
• Maximum switching voltage: 600VAC (identical)
• Coil power: 600VA (identical)
• Auxiliary contacts feature (present in both)

Mechanical Compatibility Criteria:

• Mounting type: Chassis Mount (identical)
• Termination style: Screw Terminal (identical)
• Manufacturer: Siemens (identical)

Functional Difference: The CLM32031 substitute operates as a 3-pole contactor (3PST-NO) compared to the 2-pole configuration (DPST-NO) of the CLM22031. This represents an expansion in switching capability while maintaining all other electrical and mechanical parameters. The CLM32031 is classified as active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The CLM32031 serves as the direct substitute for the obsolete CLM22031 based on electrical and mechanical parameter alignment. Both components maintain identical coil voltage (110–120VAC), current rating (20A), maximum switching voltage (600VAC), and coil power (600VA) specifications. Mounting configuration and termination style are identical, ensuring physical compatibility in existing installations.

The primary functional distinction is the pole configuration: CLM32031 provides 3-pole switching capability versus the 2-pole configuration of CLM22031. This expanded capability does not compromise backward compatibility in applications requiring 2-pole operation, as the additional pole remains available for extended circuit control.

The CLM32031 holds active product status with Siemens, ensuring continued manufacturing, technical support, and supply chain availability. Both components share identical compliance classifications (RoHS non-compliant, REACH Unaffected, ECCN EAR99), maintaining regulatory consistency in system design.

Frequently Asked Questions (FAQ)

Q: Can the CLM32031 directly replace the CLM22031 in existing installations?

A: Yes. The CLM32031 maintains identical electrical parameters (coil voltage, current rating, switching voltage, coil power) and mechanical specifications (mounting type, termination style) as the CLM22031. The 3-pole configuration of the CLM32031 provides additional switching capability while preserving all core functional requirements of the 2-pole CLM22031.

Q: What is the primary reason for substitution?

A: The CLM22031 is classified as obsolete product status. The CLM32031 is an active Siemens product, ensuring ongoing availability, manufacturing support, and supply chain continuity.

Q: Are there differences in packaging between these parts?

A: The CLM22031 is specified with dash packaging notation, while the CLM32031 is packaged in boxes. Both components utilize identical screw terminal termination and chassis mount configuration.

Q: Do both parts comply with the same regulatory standards?

A: Yes. Both CLM22031 and CLM32031 share identical RoHS status (non-compliant), REACH status (Unaffected), and ECCN classification (EAR99), maintaining regulatory consistency in system applications.

Q: What is the inventory status of these parts?

A: The CLM22031 has 928 pieces in stock as new original inventory. The CLM32031 has 1070 pieces in stock as new original inventory, providing robust supply availability for the active substitute model.

Q: How does the 3-pole configuration of CLM32031 affect circuit design compared to the 2-pole CLM22031?

A: The CLM32031 provides an additional switching pole (3PST-NO versus DPST-NO), enabling control of three independent circuits simultaneously. Applications requiring only 2-pole switching can utilize the CLM32031 with the third pole left unconnected, maintaining full compatibility with CLM22031 circuit designs.
