Parameter Comparison

Engineering Selection Recommendations

Both the RP104PJ822CS and YC124-JR-078K2L are Active product status components with full RoHS3 compliance and REACH Unaffected designation, confirming regulatory alignment for current and future applications. The electrical parameters are identical across resistance, tolerance, power rating, and temperature coefficient specifications. The mechanical footprint and pin configuration are equivalent, supporting direct PCB layout compatibility.

The YC124-JR-078K2L exhibits a maximum seated height of 0.022" (0.55mm) compared to 0.018" (0.45mm) for the RP104PJ822CS. This 0.004" (0.10mm) height differential is within typical PCB assembly tolerances and does not restrict substitution in standard surface-mount applications. Component selection should be based on supply availability, lead time requirements, and procurement cost considerations, as both parts satisfy identical functional and compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the YC124-JR-078K2L directly replace the RP104PJ822CS on an existing PCB?

A: Yes. Both components share identical electrical specifications (8.2k Ohm, ±5% tolerance, 62.5mW per element, ±200ppm/°C), pin configuration (8-pin isolated network), and package footprint (0804, Convex, Long Side Terminals). The 0.004" height difference is within standard assembly tolerances and does not affect PCB clearance or functionality.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components are RoHS3 compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited) rating. Regulatory and environmental certifications are equivalent.

Q: What is the significance of the "Isolated" circuit type?

A: The Isolated circuit type indicates that each of the four resistor elements operates independently with no internal connections between resistors. This configuration is critical for applications requiring separate signal paths or independent biasing networks. Both substitute parts maintain this isolation topology.

Q: Does packaging format affect substitution eligibility?

A: The RP104PJ822CS is supplied in standard packaging, while the YC124-JR-078K2L is available in Cut Tape (CT) format. Packaging format does not affect electrical or mechanical compatibility; it only impacts handling, storage, and automated assembly processes. Component functionality remains identical regardless of packaging presentation.

Q: What operating conditions are supported by both parts?

A: Both components operate across the temperature range of -55°C to 155°C with a temperature coefficient of ±200ppm/°C. This specification ensures stable resistance values across industrial, automotive, and extended-temperature applications.
