CMA60125 Solid State Relay SPST-NO 125A 48-660V Equivalent & Substitute Parts

Part Overview

The CMA60125 is a solid state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 125A load current across 48V to 660V output range. This component features a hockey puck form factor with screw terminal connections and zero-cross AC output switching. The CMA60125 is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs requiring this functional specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CMA60125 are qualified based on the following critical parameters that must remain constant:

• Circuit configuration: SPST-NO (1 Form A)
• Load current rating: 125 A
• Output voltage range: 48 V ~ 660 V
• Package / case: Hockey Puck
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Output type: AC, Zero Cross
• RoHS compliance

The substitute parts listed below maintain these core electrical and mechanical specifications. Variations in input voltage range and product status are noted but do not affect functional substitution for applications within the specified load and output voltage parameters.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (84137181, CWA48125, HA60125) are active products with current manufacturing status, providing supply continuity for applications previously using the obsolete CMA60125. All substitute parts maintain RoHS compliance and identical electrical ratings for load current and output voltage specifications.

The 84137181 and CWA48125 are manufactured by Sensata Technologies, maintaining the original equipment manufacturer lineage. The HA60125 is manufactured by Sensata-Crydom, a related manufacturer within the Sensata group.

All substitute parts accept input voltage ranges of 90 ~ 280 VAC, which encompasses the original CMA60125 input specification of 90 ~ 140 VAC. This expanded input range provides additional operational flexibility without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CMA60125 be directly replaced with any of the listed substitute parts?

A: Yes. The substitute parts 84137181, CWA48125, and HA60125 maintain identical circuit configuration, load current rating, output voltage range, package form factor, mounting type, and termination style. Direct mechanical and electrical substitution is supported for applications operating within the specified parameters.

Q: What is the significance of the expanded input voltage range in the substitute parts?

A: The substitute parts accept 90 ~ 280 VAC input, compared to the CMA60125 specification of 90 ~ 140 VAC. This expanded range does not affect substitution compatibility; it represents an enhancement in the substitute designs that provides broader operational flexibility for control circuits.

Q: Are all substitute parts RoHS compliant?

A: Yes. The CMA60125 and all three substitute parts (84137181, CWA48125, HA60125) are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What is the difference between the Sensata Technologies and Sensata-Crydom manufactured parts?

A: Both manufacturers are part of the Sensata Technologies group. The HA60125 (Sensata-Crydom) and the 84137181 and CWA48125 (Sensata Technologies) are functionally equivalent for the specified application parameters. Selection may be based on availability, lead time, or existing supply chain preferences.

Q: Does the hockey puck package form factor remain consistent across all substitute parts?

A: Yes. All substitute parts maintain the hockey puck package / case configuration with chassis mount orientation and screw terminal connections, ensuring mechanical compatibility with existing mounting and connection infrastructure.
