Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAY16-103J4AS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 10k Ohm
• Tolerance: ±5%
• Circuit configuration: Isolated (4 independent resistors)
• Power rating per element: 63mW
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 125°C
• Pin count: 8

Mechanical Parameters:

• Package type: 1206 (3216 Metric)
• Terminal configuration: Convex, Long Side Terminals
• Mounting method: Surface Mount

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1

The CAY16A-103J4AS meets all electrical and mechanical requirements for direct substitution. Both components share identical resistance, tolerance, power rating, temperature coefficient, and package specifications. The primary distinction is product status: CAY16A-103J4AS is active production, while CAY16-103J4AS is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The CAY16A-103J4AS is the direct equivalent substitute for the obsolete CAY16-103J4AS. Both components are manufactured by Bourns Inc. and maintain identical electrical specifications, mechanical dimensions, and compliance certifications.

Selection Basis:

The CAY16A-103J4AS is recommended for new designs and production continuity due to its active product status. This component carries ROHS3 compliance and maintains full electrical and thermal performance equivalence with the original part.

The primary operational difference is packaging format: CAY16A-103J4AS is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations. The original CAY16-103J4AS was supplied in bulk packaging.

Both components are suitable for applications requiring isolated resistor networks with stable performance across the -55°C to 125°C operating range and are compatible with standard surface mount assembly processes for 1206 package components.

Frequently Asked Questions (FAQ)

Q: Can the CAY16A-103J4AS be used as a direct replacement for the CAY16-103J4AS?

A: Yes. The CAY16A-103J4AS is a direct electrical and mechanical equivalent. All critical parameters including resistance value, tolerance, power rating, temperature coefficient, pin configuration, and package dimensions are identical. The components are interchangeable at the circuit level.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging format. The CAY16-103J4AS is obsolete and supplied in bulk packaging. The CAY16A-103J4AS is in active production and supplied in Tape & Reel format, which is standard for automated surface mount assembly.

Q: Are there any thermal or electrical performance differences?

A: No. Both components operate across -55°C to 125°C with identical ±200ppm/°C temperature coefficient and 63mW power per element. Electrical performance is equivalent.

Q: Will the CAY16A-103J4AS fit the same PCB footprint?

A: Yes. Both components use the 1206 (3216 Metric) package with convex, long side terminals. PCB footprints are identical, and no layout modifications are required.

Q: Are both components RoHS compliant?

A: Yes. Both the CAY16-103J4AS and CAY16A-103J4AS are ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging is used for manual handling and small-quantity applications. Tape & Reel packaging is designed for automated pick-and-place assembly equipment used in high-volume manufacturing. The component specifications and performance are identical; only the delivery format differs.
