CMD24125 Solid State Relay SPST-NO 125A 24-280V Equivalent & Substitute Parts

Part Overview

The CMD24125 is a solid state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 125A load current and 24-280V AC output. Manufactured by Sensata-Crydom in a hockey puck chassis mount package with screw terminal connections, this component is classified as obsolete. Due to its obsolete status, identifying active equivalent and substitute parts is essential for system maintenance, redesign, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CMD24125 is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC, Zero Cross
• Input voltage range: 3 ~ 32VDC
• Load voltage range: 24 V ~ 280 V
• Load current rating: 125 A
• Mounting type: Chassis Mount
• Package type: Hockey Puck
• Termination style: Screw Terminal

All substitute parts listed maintain identical electrical specifications and mechanical form factors. The primary distinction between substitutes is product status (active vs. obsolete) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using CMD24125, the following active substitutes are electrically and mechanically equivalent:

84137080 (Sensata Technologies, GN Series): This part maintains full electrical and mechanical compatibility with CMD24125. Classified as active product status with RoHS compliance certification. Suitable for new designs and system replacements where Sensata Technologies sourcing is acceptable.

CWD24125 (Sensata-Crydom, CW24 Series): This part maintains full electrical and mechanical compatibility with CMD24125. Classified as active product status with ROHS3 compliance certification and REACH compliance status. Recommended for applications requiring enhanced regulatory compliance documentation or where Sensata-Crydom continuity is preferred.

Both substitutes provide identical electrical performance and physical form factor compatibility. Selection between them depends on supply chain preferences, compliance documentation requirements, and manufacturer sourcing strategy.

Frequently Asked Questions (FAQ)

Q: Can 84137080 directly replace CMD24125 in existing applications? A: Yes. The 84137080 maintains identical electrical specifications (125A at 24-280V AC output, 3-32VDC input), circuit configuration (SPST-NO with zero cross), mounting type (chassis mount), and package form factor (hockey puck with screw terminals). No circuit modifications are required.

Q: What is the difference between CWD24125 and 84137080? A: Both parts are electrically and mechanically identical to CMD24125. The primary differences are manufacturer designation (Sensata-Crydom vs. Sensata Technologies), series designation (CW24 vs. GN), and compliance certifications (ROHS3 vs. RoHS). Electrical performance and physical compatibility are equivalent.

Q: Why is CMD24125 listed as obsolete? A: CMD24125 is no longer in active production. The active equivalents 84137080 and CWD24125 represent the current product line offerings from Sensata for this relay specification.

Q: Are there any packaging differences between these parts? A: All three parts use identical hockey puck chassis mount packages with screw terminal connections. Packaging format (bulk) is consistent across active substitutes.

Q: Which substitute should be selected for new designs? A: Both 84137080 and CWD24125 are suitable for new designs. Selection should be based on supply chain availability, preferred manufacturer relationship, and specific compliance requirements (ROHS3 vs. RoHS). Electrical performance is identical.

Q: Is the input voltage range identical across all parts? A: Yes. All parts operate with 3-32VDC input voltage range and are rated for 24-280V AC load voltage with 125A maximum load current.
