CMA6090 Equivalent & Substitute Parts Reference

Part Overview

The CMA6090 is a solid-state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 90A load current at 48-660V output voltage range. Manufactured by Sensata-Crydom, this hockey puck-style chassis mount relay features AC zero-cross switching and screw terminal connections. The CMA6090 is designated as Last Time Buy, indicating production discontinuation. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications requiring this relay specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CMA6090 are qualified based on the following critical parameters:

Mandatory Compatibility Criteria:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC, Zero Cross
• Load voltage range: 48 V – 660 V (minimum)
• Package style: Hockey Puck
• Mounting type: Chassis Mount
• Termination style: Screw Terminal

Allowable Variations:

• Load current rating: Equal to or greater than 90 A
• Input voltage range: Equal to or greater than the original specification
• Product status: Active or Last Time Buy
• RoHS compliance: RoHS Compliant or ROHS3 Compliant

Three substitute parts meet these criteria: HA6090, CWA4890, and 84137141. Each maintains the core electrical and mechanical specifications while offering different product lifecycle statuses and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

HA6090 is the direct functional equivalent to CMA6090. Both parts share identical load current (90 A) and load voltage specifications. HA6090 is in Active product status with expanded input voltage range (90–280 VAC versus 90–140 VAC), providing greater design flexibility. RoHS compliance is maintained. This part is recommended as the primary substitute for new designs and ongoing production.

CWA4890 maintains the same 90 A load current and 48–660 V load voltage range as CMA6090. Input voltage range is expanded to 90–280 VAC. Product status is Active with ROHS3 compliance and REACH compliance documentation. This part is suitable for applications requiring enhanced regulatory compliance documentation.

84137141 is rated for 100 A load current, exceeding the CMA6090 specification by 10 A. All other electrical parameters remain compatible. Product status is Active with ROHS3 compliance and REACH compliance. This part is appropriate for applications where higher current capacity provides design margin or future load growth accommodation.

Frequently Asked Questions (FAQ)

Q: Can HA6090 be used as a direct replacement for CMA6090? A: Yes. HA6090 maintains identical load current (90 A) and load voltage range (48–660 V) specifications. The expanded input voltage range (90–280 VAC) is a superset of CMA6090's range (90–140 VAC), ensuring compatibility in all applications where CMA6090 was specified.

Q: What is the difference between CWA4890 and HA6090? A: Both parts are functionally equivalent to CMA6090 with identical 90 A load current and 48–660 V load voltage specifications. CWA4890 carries ROHS3 and REACH compliance certifications, while HA6090 carries RoHS compliance. Selection depends on regulatory requirements for the end application.

Q: Can 84137141 be substituted for CMA6090 in all applications? A: 84137141 is electrically compatible with CMA6090 across all specified parameters. The 100 A current rating exceeds the 90 A requirement, providing additional capacity margin. Mechanical compatibility (hockey puck package, screw terminals, chassis mount) is identical. Substitution is valid for all CMA6090 applications.

Q: Are all substitute parts available in the same hockey puck package? A: Yes. CMA6090, HA6090, CWA4890, and 84137141 are all packaged in hockey puck style with screw terminal connections and chassis mount configuration, ensuring mechanical interchangeability.

Q: What compliance certifications should I verify for my application? A: CMA6090 and HA6090 carry RoHS compliance. CWA4890 and 84137141 carry ROHS3 compliance. CWA4890 and 84137141 also carry REACH compliance documentation. Verify which certifications are required by your end-use application and regulatory jurisdiction before final part selection.
