Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN104PJ820CS is determined by the following critical parameters:

Electrical Parameters (Must Match):

• Resistance value: 82 Ohm
• Tolerance: ±5%
• Number of resistors: 4
• Circuit topology: Isolated
• Power per element: 62.5mW
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Pin count: 8

Mechanical Parameters (Must Match):

• Package designation: 0804
• Mounting type: Surface Mount
• Physical dimensions: 0.079" L x 0.039" W (2.00mm x 1.00mm)

Compliance Parameters (Must Match):

• RoHS3 Compliance
• Moisture Sensitivity Level 1

The YC124-JR-0782RL from YAGEO meets all electrical and compliance requirements. Physical terminal configuration differs (convex vs. concave), and maximum seated height varies by 0.002" (0.05mm), which remains within acceptable PCB assembly tolerances for 0804 package class components.

Parameter Comparison

Engineering Selection Recommendations

The YC124-JR-0782RL is a direct functional equivalent for the obsolete RN104PJ820CS. Selection rationale is based on the following factors:

Electrical Equivalence: All critical electrical parameters match exactly, including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. The isolated 4-resistor network topology is identical.

Compliance Alignment: Both components maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with current manufacturing and environmental standards.

Product Status: The YC124-JR-0782RL is active production status, providing long-term availability and supply chain stability compared to the obsolete RN104PJ820CS.

Physical Compatibility: Terminal configuration differs (convex vs. concave), but both utilize long-side terminal design in 0804 package. Height difference of 0.002" (0.05mm) is within standard PCB assembly tolerances and does not impact reflow soldering or component placement.

Packaging Availability: YC124-JR-0782RL is available in Tape & Reel format, supporting automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can YC124-JR-0782RL replace RN104PJ820CS in existing designs without PCB modification?

A: Yes. Both components share identical electrical specifications, pin count (8), and 0804 package dimensions (0.079" L x 0.039" W). The terminal configuration difference (convex vs. concave) does not require PCB redesign, as both utilize long-side terminal placement. Height variation of 0.002" (0.05mm) is within standard surface mount assembly tolerances.

Q: What is the significance of the terminal configuration difference?

A: Terminal configuration (concave vs. convex) refers to the physical profile of the component body. This difference does not affect electrical performance or PCB footprint compatibility. Both configurations are designed for standard 0804 package reflow soldering processes.

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

A: No. Both components are ROHS3 compliant and carry MSL Level 1 rating. Compliance certifications are equivalent.

Q: Why is the RN104PJ820CS listed as obsolete?

A: Product status reflects manufacturer discontinuation. The YC124-JR-0782RL provides functional continuity for applications previously using the Samsung component.

Q: What is the difference between the HTSUS codes listed for each part?

A: HTSUS codes (8533.21.0010 vs. 8533.21.0020) reflect tariff classification differences based on manufacturer origin and packaging format. Both codes classify these components as resistor networks/arrays. This difference does not affect technical compatibility or performance.

Q: Can these parts be used interchangeably in automotive applications?

A: The YC124-JR-0782RL is qualified for automotive AEC-Q200 applications. Design requirements should be verified against specific application standards and qualification documentation.
