Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAY10-220J4AS is determined by strict equivalence across the following critical parameters:

• Resistance value: 22 Ohm
• Tolerance: ±5%
• Number of resistors: 4
• Circuit configuration: Isolated
• Power per element: 63mW
• Temperature coefficient: ±250ppm/°C
• Operating temperature range: -55°C to 125°C
• Package type: 0804, Convex, Long Side Terminals
• Mounting type: Surface Mount
• Pin count: 8

The CAY10A-220J4AS meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The CAY10A-220J4AS is the direct substitute for the obsolete CAY10-220J4AS. Both parts are manufactured by Bourns Inc. and maintain identical electrical specifications, package dimensions, and compliance certifications. The CAY10A-220J4AS carries active product status, ensuring ongoing availability and supply chain continuity. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. 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 functional performance or board layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CAY10A-220J4AS be used as a direct replacement for the CAY10-220J4AS?

A: Yes. The CAY10A-220J4AS is electrically and mechanically equivalent to the CAY10-220J4AS across all critical parameters including resistance value, tolerance, power rating, temperature coefficient, operating temperature range, and package configuration.

Q: What is the difference between the CAY10-AS and CAY10A-AS series?

A: The CAY10A-AS series represents the active product line continuation of the obsolete CAY10-AS series. Electrical and mechanical specifications remain identical; the primary difference is product status and availability.

Q: Are there any PCB layout considerations when substituting these parts?

A: No significant layout changes are required. Both parts use identical 0804 package dimensions and 8-pin configurations. The 0.002" (0.05mm) height difference is within standard PCB assembly tolerances.

Q: Do both parts meet automotive qualification standards?

A: The CAY10A-220J4AS is qualified to AEC-Q200 automotive standards. The CAY10-220J4AS does not list automotive applications in the provided specifications.

Q: Are both parts available in the same packaging format?

A: The CAY10-220J4AS is available in standard packaging. The CAY10A-220J4AS is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly.
