RP102PJ102CS - 2 Resistor Network Array 1K Ohm 0404 Surface Mount

Part Overview

The RP102PJ102CS is a 2-element isolated resistor network array manufactured by Samsung Electro-Mechanics. This surface mount component features dual 1K Ohm resistors with ±5% tolerance in a compact 0404 (1010 Metric) package. The part is currently active in production and widely available. Alternative part numbers are identified to support supply chain continuity, design flexibility, and inventory optimization when the primary component experiences availability constraints or when equivalent electrical and mechanical specifications are required for specific applications.

Parameter Comparison

Engineering Selection Recommendations

RP102PJ102CS (Samsung Electro-Mechanics): This is the primary component specification. It maintains active production status with ROHS3 compliance and demonstrates high stock availability (1143 units). Selection of this part is appropriate for new designs and ongoing production.

YC122-JR-071KL (YAGEO): This substitute offers active production status equivalent to the primary part. It provides ROHS3 compliance and superior inventory availability (8736 units) compared to the primary manufacturer. The part is qualified for automotive applications meeting AEC-Q200 standards, supporting extended temperature operational reliability. Selection of this part is supported when primary component allocation is constrained or when automotive-grade qualification is required.

MNR02MRAPJ102 (Rohm Semiconductor): This substitute meets all electrical and mechanical parameters and provides ROHS3 compliance. However, the part is discontinued at DiGi Electronics, which may create long-term supply risk. Selection of this part is not recommended for new designs or when longer product lifecycle is required. It may be considered only for specific legacy applications where supplier relationship or existing inventory justifies use.

Frequently Asked Questions (FAQ)

Q: Are all three parts electrically interchangeable? A: Yes. All three parts share identical electrical specifications: 1k Ohm resistance, ±5% tolerance, 62.5mW power per element, ±200ppm/°C temperature coefficient, and -55°C to 155°C operating range. They function equivalently in circuit designs utilizing these parameters.

Q: Are all three parts mechanically interchangeable? A: Yes. All three parts use the identical 0404 (1010 Metric) surface mount package with 4 pins. They are compatible with the same PCB footprint and mounting process. Minor height differences (0.018" vs 0.016") do not affect mechanical interchangeability for standard assembly processes.

Q: What is the primary reason to consider a substitute part? A: Substitute parts address supply chain constraints affecting the primary component. When RP102PJ102CS allocation is limited or delivery schedules are extended, equivalent parts from alternative manufacturers provide design continuity without circuit redesign.

Q: Which substitute part is recommended as a first alternative? A: YC122-JR-071KL is the recommended first alternative. It maintains active production status, provides the highest inventory availability, and includes automotive-grade qualification for applications requiring extended reliability assurance.

Q: Can MNR02MRAPJ102 be used in new designs? A: MNR02MRAPJ102 is not recommended for new designs. Its discontinued status at DiGi Electronics creates procurement risk for long-term production support. This part should be reserved for legacy applications only.

Q: Does package selection affect PCB layout requirements? A: No. All three parts use identical 0404 (1010 Metric) packages with the same footprint dimensions (0.039" L x 0.039" W). PCB layout modifications are not required when switching between equivalent parts.

Q: Are there compliance differences between the three parts? A: No significant compliance differences exist. All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. YC122-JR-071KL adds automotive AEC-Q200 qualification, extending reliability assurance for automotive applications.
