RP164PJ302CS Equivalent & Substitute Parts

Part Overview

The RP164PJ302CS is a 4-resistor isolated network array manufactured by Samsung Electro-Mechanics, featuring 3kΩ resistors with ±5% tolerance in a 1206 surface mount package. This component is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing design requirements and production continuity. The part operates across a temperature range of -55°C to 155°C with a temperature coefficient of ±200ppm/°C and is RoHS3 compliant with unlimited moisture sensitivity rating.

Substitute Part Grouping Explanation

Substitution of the RP164PJ302CS is determined by strict equivalence across the following critical parameters: resistance value (3kΩ), circuit topology (isolated 4-resistor network), package form factor (1206 with 8 pins), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3, REACH Unaffected).

The identified substitute parts maintain these core specifications while varying in tolerance grade and power dissipation capacity. The YC164-JR-073KL from YAGEO provides direct functional equivalence with identical tolerance (±5%) and power rating (62.5mW per element), with the addition of automotive-grade qualification (AEC-Q200). The RAVF164DFT3K00 from Stackpole Electronics Inc represents an upgraded alternative, offering improved tolerance (±1%) and increased power dissipation (100mW per element) while maintaining all other critical parameters and automotive qualification.

Engineering Selection Recommendations

The YC164-JR-073KL from YAGEO serves as the direct functional equivalent to the obsolete RP164PJ302CS. Both components share identical electrical specifications (3kΩ, ±5% tolerance, 62.5mW per element) and mechanical form factor. The YAGEO part is currently in active production status with automotive-grade qualification (AEC-Q200), ensuring long-term availability and supply chain stability.

The RAVF164DFT3K00 from Stackpole Electronics Inc functions as an upgraded alternative for applications requiring enhanced precision and power handling. This part maintains all core specifications while offering tighter tolerance (±1% versus ±5%) and increased power dissipation capacity (100mW versus 62.5mW per element). The RAVF164DFT3K00 also carries automotive-grade qualification (AEC-Q200) and active production status.

Both substitute parts are RoHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the original component. Selection between the two substitutes depends on application-specific requirements for tolerance grade and thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the YC164-JR-073KL directly replace the RP164PJ302CS without circuit modification?

A: Yes. The YC164-JR-073KL maintains identical electrical and mechanical specifications, including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. The 1206 package form factor and 8-pin configuration are identical, enabling direct substitution in existing PCB layouts.

Q: What is the difference between the YC164-JR-073KL and RAVF164DFT3K00 substitutes?

A: The primary differences are tolerance grade and power dissipation capacity. The YC164-JR-073KL matches the original RP164PJ302CS with ±5% tolerance and 62.5mW per element. The RAVF164DFT3K00 offers improved tolerance (±1%) and higher power rating (100mW per element). Both maintain identical resistance value, temperature coefficient, and operating temperature range.

Q: Are there height differences between the substitute parts and the original?

A: The YC164-JR-073KL has a maximum seated height of 0.028" (0.70mm), compared to 0.024" (0.60mm) for the RP164PJ302CS and RAVF164DFT3K00. This 0.004" (0.10mm) difference may require verification in applications with tight vertical clearance constraints.
