Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAY10-473J4AS is determined by strict equivalence across the following critical parameters:

• Resistance value: 47kΩ
• Tolerance: ±5%
• Circuit topology: Isolated configuration
• Number of resistor elements: 4
• Power rating per element: 63mW
• Temperature coefficient: ±250ppm/°C
• Package form factor: 0804 with convex, long side terminals
• Pin count: 8
• Operating temperature range: -55°C to 125°C
• Surface mount compatibility

The CAY10A-473J4AS meets all substitution criteria as an active-status alternative within the same product family, offering identical electrical specifications and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CAY10A-473J4AS is the direct substitute for the obsolete CAY10-473J4AS. Both components maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the CAY10A-473J4AS carries active status with confirmed current availability, whereas the CAY10-473J4AS is obsolete. Both components satisfy ROHS3 compliance and REACH unaffected requirements. The seated height differential of 0.002" (0.05mm) between the two parts remains within typical PCB assembly tolerances and does not affect functional compatibility. Selection of the CAY10A-473J4AS is appropriate for new designs and replacement applications requiring active component sourcing.

Frequently Asked Questions (FAQ)

Q: Can the CAY10A-473J4AS directly replace the CAY10-473J4AS in existing designs?

A: Yes. Both components share identical electrical specifications (47kΩ, ±5% tolerance, 63mW per element, ±250ppm/°C) and mechanical form factor (0804 package, 8-pin surface mount). The 0.002" height difference is within standard PCB assembly tolerances.

Q: What is the primary reason for substitution?

A: The CAY10-473J4AS is obsolete. The CAY10A-473J4AS provides equivalent functionality with active product status and current inventory availability.

Q: Are there compliance differences between the two parts?

A: No. Both components are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1, Unlimited).

Q: Does the package designation differ between these parts?

A: Both use the 0804 package with convex, long side terminals. Mechanical dimensions and pin configuration are identical, ensuring PCB layout compatibility.
