Substitute Part Grouping Explanation

Substitution eligibility for the CAY16-181J8LF is determined by strict equivalence across the following parameters: resistance value (180 Ohm), tolerance (±5%), number of resistors (8), circuit topology (isolated), power rating per element (62.5mW), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 125°C), pin count (16), and package configuration (1506 with convex, long side terminals). The EXB-2HV181JV from Panasonic Electronic Components meets all these criteria and qualifies as a direct functional equivalent. The substitute maintains identical electrical specifications and mechanical compatibility while offering active product status and automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

The EXB-2HV181JV is the qualified substitute for the CAY16-181J8LF. Both components are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications. The Panasonic part carries active product status, ensuring long-term availability and supply chain stability compared to the obsolete Bourns component. The EXB-2HV181JV includes automotive AEC-Q200 qualification, providing additional reliability assurance for applications requiring automotive-grade components. The marginal difference in seated height (0.022" versus 0.024") is within typical PCB assembly tolerances and does not affect functional compatibility or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can the EXB-2HV181JV be used as a direct replacement for the CAY16-181J8LF?

A: Yes. Both components share identical electrical specifications (180 Ohm, ±5% tolerance, 62.5mW per element, ±200ppm/°C temperature coefficient, -55°C to 125°C operating range) and mechanical compatibility (1506 package, 16 pins, surface mount). Pin-for-pin substitution is supported without circuit modification.

Q: What is the significance of the product status difference?

A: The CAY16-181J8LF is classified as obsolete, indicating Bourns has discontinued production and support. The EXB-2HV181JV maintains active status, ensuring continued manufacturing, technical support, and procurement availability from Panasonic.

Q: Does the height difference between the two parts affect PCB assembly?

A: The seated height difference (0.022" for EXB-2HV181JV versus 0.024" for CAY16-181J8LF) is 0.002" and falls within standard PCB assembly tolerances. No design modifications are required.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the CAY16-181J8LF and EXB-2HV181JV are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What additional qualification does the Panasonic part offer?

A: The EXB-2HV181JV carries automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability standards. The Bourns part does not specify this qualification.
