Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMD6050 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CWD4850 qualifies as a direct equivalent based on the following criteria:

• Identical circuit configuration (SPST-NO, 1 Form A)
• Identical output type (AC, Zero Cross)
• Identical input voltage range (4 ~ 32VDC)
• Identical load voltage range (48V ~ 660V)
• Identical load current rating (50A)
• Identical mounting type (Chassis Mount)
• Identical package type (Hockey Puck)
• Identical termination style (Screw Terminal)
• Equivalent regulatory compliance (RoHS3 Compliant vs. RoHS Compliant)

Both parts are manufactured by Sensata-Crydom and maintain active product status. The CWD4850 belongs to the CW48 series, while the CMD6050 belongs to the CMD60 series, representing different product lines within the manufacturer's SSR portfolio.

Parameter Comparison

Engineering Selection Recommendations
