RP104PJ820CS 82 Ohm Isolated 4-Resistor Network Array Equivalent & Substitute Parts

Part Overview

The RP104PJ820CS is a surface-mount resistor network array manufactured by Samsung Electro-Mechanics. This component is a 4-resistor isolated network with 82 Ohm resistance per element, rated at 62.5mW power dissipation per element, and housed in a 0804 package with convex, long-side terminals. The part is currently in active production status. Substitute parts are identified when original inventory becomes unavailable, when supply chain constraints occur, or when design flexibility permits equivalent component selection within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the RP104PJ820CS are qualified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Primary Matching Criteria:

• Resistance value: 82 Ohm (exact match required)
• Tolerance: ±5% (exact match required)
• Number of resistors: 4 (exact match required)
• Circuit type: Isolated (exact match required)
• Power per element: 62.5mW (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Package type: 0804, Convex, Long Side Terminals (exact match required)
• Number of pins: 8 (exact match required)
• Mounting type: Surface Mount (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria without exception. Physical dimensions (length, width, and seated height) may vary within acceptable manufacturing tolerances and do not disqualify substitution when all electrical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

RP104PJ820CS (Samsung Electro-Mechanics) - Primary Selection

The RP104PJ820CS is the original specified component with active production status. Current inventory of 920 pieces is available. This part is recommended for new designs and ongoing production when supply is confirmed.

MNR04MRAPJ820 (Rohm Semiconductor) - Secondary Selection

The MNR04MRAPJ820 is electrically and mechanically equivalent to the RP104PJ820CS. However, this part is discontinued at DiGi Electronics, indicating limited future availability. The seated height is 0.020" (0.50mm) compared to 0.018" (0.45mm) for the Samsung part. This 0.002" difference is within typical PCB assembly tolerances and does not affect circuit performance. Inventory of 3406 pieces is currently available. This part is suitable for substitution only when Samsung supply is exhausted and the height variation is acceptable for the application.

YC124-JR-0782RL (YAGEO) - Recommended Substitute

The YC124-JR-0782RL is electrically and mechanically equivalent to the RP104PJ820CS. This part maintains active production status with the highest current inventory of 16,393 pieces. The seated height is 0.022" (0.55mm), representing a 0.004" maximum difference from the Samsung specification. This variation is within standard PCB assembly tolerances. YAGEO qualification includes automotive AEC-Q200 compliance, DDRAM, and SDRAM applications, indicating broad industrial acceptance. This part is the preferred substitute when Samsung supply is unavailable.

Compliance Summary

All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All parts carry MSL 1 (Unlimited) moisture sensitivity rating, requiring no special storage precautions.

Frequently Asked Questions (FAQ)

Q1: Can MNR04MRAPJ820 be used as a direct replacement for RP104PJ820CS?

A: Yes. The MNR04MRAPJ820 meets all electrical specifications (82 Ohm, ±5%, 62.5mW per element, ±200ppm/°C, -55°C to 155°C operating range) and physical requirements (0804 package, 8-pin isolated configuration, surface mount). The seated height difference of 0.002" (0.50mm vs. 0.45mm) is within standard PCB assembly tolerances and does not affect circuit function. However, this part is discontinued at DiGi Electronics, limiting future availability.

Q2: Is YC124-JR-0782RL suitable for applications requiring the RP104PJ820CS?

A: Yes. The YC124-JR-0782RL is electrically identical to the RP104PJ820CS across all specified parameters. The seated height of 0.022" (0.55mm) represents a 0.004" maximum variation from the Samsung specification, which is within acceptable PCB assembly tolerances. YAGEO's active production status and higher inventory (16,393 pieces) make this the preferred substitute when Samsung supply is constrained.

Q3: What is the significance of the seated height differences among these parts?

A: Seated height variations of 0.002" to 0.004" among these parts are within standard surface-mount assembly tolerances (typically ±0.010" or greater). These differences do not affect electrical performance, PCB routing, or component placement accuracy in standard manufacturing processes. Height variations become relevant only in applications with extreme space constraints or specialized assembly requirements.

Q4: Are all three parts suitable for automotive applications?

A: The RP104PJ820CS and MNR04MRAPJ820 specifications do not explicitly list automotive qualification. The YC124-JR-0782RL carries AEC-Q200 automotive qualification, DDRAM, and SDRAM application ratings. For automotive applications, YC124-JR-0782RL is the recommended choice among the three options.

Q5: What is the difference between "Active" and "Discontinued at DiGi Electronics" product status?

A: "Active" status indicates the manufacturer continues production and the part is available through distribution channels. "Discontinued at DiGi Electronics" indicates the specific distributor has ceased stocking the part, though the manufacturer may continue production through other channels. For long-term supply security, parts with "Active" status are preferred.

Q6: Do these parts require special handling or storage conditions?

A: No. All three parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture-related storage restrictions. Standard ESD precautions for surface-mount components apply.

Q7: Can these parts be intermixed in the same production batch?

A: Yes. All three parts are electrically and mechanically equivalent within specified tolerances. However, manufacturing best practices recommend using a single part number per production run to maintain traceability and simplify quality documentation.
