Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAY10-330J4AS is determined by strict equivalence across the following critical parameters:

• Resistance value: 33 Ohm
• Tolerance: ±5%
• Circuit topology: Isolated configuration
• Number of resistor elements: 4
• Power rating per element: 63mW
• Temperature coefficient: ±250ppm/°C
• Operating temperature range: -55°C ~ 125°C
• Package specification: 0804, Convex, Long Side Terminals
• Pin count: 8
• Surface mount compatibility

The CAY10A-330J4AS qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction is product status: CAY10A-330J4AS is active production, whereas CAY10-330J4AS is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The CAY10A-330J4AS is the direct substitute for the obsolete CAY10-330J4AS. Both parts maintain identical electrical specifications and mechanical compatibility. The CAY10A-330J4AS carries active product status with automotive AEC-Q200 qualification, providing enhanced availability and supply chain continuity. Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and automotive applications. The maximum seated height difference of 0.002" (0.05mm) between the two parts is negligible for standard PCB assembly processes and does not affect circuit performance or board layout compatibility.
