Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN102PJ3R0CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 3 Ohms
• Tolerance: ±5%
• Number of resistor elements: 2
• Power per element: 62.5mW
• Circuit configuration: Isolated
• Pin count: 4
• Package form factor: 0404 (1010 Metric)
• Mounting technology: Surface Mount
• Operating temperature range: -55°C ~ 155°C
• Environmental compliance: ROHS3 Compliant, REACH Unaffected

Allowable Variation Parameters:

• Temperature coefficient: ±250ppm/°C to ±300ppm/°C (tighter specifications acceptable)
• Package geometry: Concave or Convex (both 0404 metric dimensions)
• Product status: Active preferred over Obsolete
• Packaging format: Tape & Reel acceptable for procurement

The YC122-JR-073RL from YAGEO meets all mandatory matching criteria and represents a direct functional equivalent with improved temperature coefficient performance (±250ppm/°C versus ±300ppm/°C) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The YC122-JR-073RL is the qualified substitute for the obsolete RN102PJ3R0CS based on the following engineering criteria:

Functional Equivalence: Both components deliver identical electrical performance across all critical parameters: 3 Ohm resistance, ±5% tolerance, 2-element isolated configuration, 62.5mW power per element, and 4-pin surface mount package in 0404 (1010 Metric) form factor.

Compliance Status: The YC122-JR-073RL maintains full ROHS3 compliance and REACH unaffected status, matching the environmental regulatory requirements of the original part. Additionally, the YAGEO part carries AEC-Q200 automotive qualification, providing enhanced reliability documentation for applications requiring automotive-grade components.

Temperature Performance: The YC122-JR-073RL exhibits superior temperature coefficient stability at ±250ppm/°C compared to the RN102PJ3R0CS specification of ±300ppm/°C, representing a tighter tolerance that enhances long-term accuracy across the full -55°C to 155°C operating range.

Physical Compatibility: Both parts occupy identical footprint dimensions (1.00mm x 1.00mm) with negligible height difference (0.40mm versus 0.45mm seated height). The geometric variation from concave to convex package profile does not affect PCB placement or reflow soldering processes for standard surface mount assembly.

Product Availability: The YC122-JR-073RL maintains active product status with established supply chain availability, eliminating procurement risk associated with the obsolete RN102PJ3R0CS designation.

Frequently Asked Questions (FAQ)

Q: Can the YC122-JR-073RL be used as a direct replacement for the RN102PJ3R0CS without circuit redesign?

A: Yes. The YC122-JR-073RL meets all mandatory electrical and mechanical specifications for direct substitution. Identical resistance value, tolerance, power rating, pin configuration, and operating temperature range ensure functional compatibility without circuit modification.

Q: What is the significance of the temperature coefficient difference (±250ppm/°C versus ±300ppm/°C)?

A: The YC122-JR-073RL temperature coefficient is tighter, meaning resistance values remain more stable across temperature variations. This represents improved performance and is acceptable for any application originally designed for the RN102PJ3R0CS.

Q: Does the package geometry change from concave to convex affect assembly or performance?

A: No. Both geometries maintain identical footprint dimensions (1.00mm x 1.00mm) and are compatible with standard surface mount assembly processes. The height difference (0.40mm versus 0.45mm) is negligible for PCB layout and reflow soldering.

Q: Is the AEC-Q200 qualification on the YC122-JR-073RL relevant for non-automotive applications?

A: AEC-Q200 qualification indicates enhanced reliability testing and quality assurance. While not required for non-automotive use, it provides additional confidence in component performance and longevity across all application categories.

Q: What is the procurement advantage of switching to the YC122-JR-073RL?

A: The YC122-JR-073RL maintains active product status with established supply chain availability, eliminating obsolescence risk. The RN102PJ3R0CS is classified as obsolete, making future procurement increasingly difficult.

Q: Are there any electrical performance differences that would affect circuit behavior?

A: No. Both components deliver identical electrical characteristics within the specified tolerance bands. The improved temperature coefficient of the YC122-JR-073RL represents enhanced stability, not a deviation from original performance requirements.
