• Circuit type: Isolated configuration (4-resistor network)
• Package: 1206 (3216 Metric) with 8 pins
• Tolerance: ±5% or better
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: Minimum -55°C ~ 155°C
• Mounting type: Surface Mount
• RoHS3 compliance

Substitution Categories:

Direct Equivalents maintain all electrical and mechanical specifications within the original design envelope. These parts are pin-compatible and functionally interchangeable without circuit modification.

Upgrade Substitutes exceed the original specifications in tolerance or power rating while maintaining full backward compatibility. These parts provide enhanced performance margins and are suitable for designs requiring improved precision or thermal headroom.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, No Circuit Modification Required):

The YC164-JR-0718RL from YAGEO is the primary direct equivalent. This part maintains identical electrical specifications (18 Ohm ±5%, 62.5mW per element, ±200ppm/°C) and operating temperature range (-55°C ~ 155°C). The part is currently in active production status with AEC-Q200 automotive qualification, ensuring long-term availability and supply chain stability. The YC164-JR-0718RL is suitable for designs where the original RP164PJ180CS specifications must be preserved exactly.

The 742X083180JP from CTS Resistor Products is a secondary direct equivalent with nearly identical specifications. This part features 63mW power per element (marginally higher than the original 62.5mW) and maintains ±5% tolerance and ±200ppm/°C temperature coefficient. The operating temperature range is -55°C ~ 125°C, which is narrower than the original part. The 742X083180JP is appropriate for applications where the upper temperature limit does not exceed 125°C and the slightly higher power rating is acceptable.

For Enhanced Performance (Upgrade Substitute):

The RAVF164DFT18R0 from Stackpole Electronics Inc is an upgrade substitute offering improved tolerance (±1% versus ±5%) and higher power rating (100mW per element versus 62.5mW). This part maintains the full operating temperature range (-55°C ~ 155°C) and is AEC-Q200 qualified. The RAVF164DFT18R0 is suitable for designs requiring tighter resistance tolerance or applications with higher thermal stress. This part is pin-compatible and requires no circuit modification.

Compliance and Availability:

All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental specifications. All active substitutes carry AEC-Q200 automotive qualification, providing design confidence for automotive and industrial applications. Current inventory levels support immediate procurement for all recommended substitutes.

Frequently Asked Questions (FAQ)

Q: Can the YC164-JR-0718RL replace the RP164PJ180CS without any circuit modifications?

A: Yes. The YC164-JR-0718RL is pin-compatible with identical electrical specifications (18 Ohm ±5%, 62.5mW per element, ±200ppm/°C) and the same operating temperature range (-55°C ~ 155°C). No circuit modifications are required for direct substitution.

Q: What is the difference between the 742X083180JP and YC164-JR-0718RL?

A: Both parts are direct equivalents with 18 Ohm ±5% resistance and ±200ppm/°C temperature coefficient. The primary difference is the operating temperature range: the 742X083180JP operates from -55°C ~ 125°C, while the YC164-JR-0718RL operates from -55°C ~ 155°C. The 742X083180JP has a marginally higher power rating (63mW versus 62.5mW per element). Select based on your application's maximum operating temperature requirement.

Q: When should I use the RAVF164DFT18R0 upgrade substitute?

A: Use the RAVF164DFT18R0 when your design requires tighter resistance tolerance (±1% versus ±5%) or when thermal margins are critical due to higher power dissipation. The 100mW per element rating provides 60% more power headroom than the original 62.5mW specification. This part is fully backward compatible and requires no circuit changes.

Q: Are all substitute parts automotive qualified?

A: The YC164-JR-0718RL, 742X083180JP, and RAVF164DFT18R0 all carry AEC-Q200 automotive qualification. The original RP164PJ180CS does not specify AEC-Q200 qualification. If automotive qualification is required for your application, select from the three active substitutes listed above.

Q: What is the package compatibility between these parts?

A: All parts use the 1206 (3216 Metric) surface mount package with 8 pins, convex long side terminals. Physical dimensions are identical (0.126" L x 0.063" W / 3.20mm x 1.60mm), ensuring PCB footprint compatibility. Height variations are minimal (0.024" to 0.028" seated height), which does not affect assembly or clearance in standard designs.

Q: Why is the RP164PJ180CS marked as obsolete?

A: The RP164PJ180CS is classified as obsolete by Samsung Electro-Mechanics. The recommended substitutes (YC164-JR-0718RL, 742X083180JP, RAVF164DFT18R0) are all in active production status, ensuring long-term availability and supply chain continuity for new designs and ongoing production support.

Q: Can I mix different substitute parts in the same design?

A: Yes, all recommended substitutes are electrically and mechanically compatible. However, for consistency in manufacturing and quality control, it is preferable to standardize on a single part number per design. If multiple substitutes are used, ensure that tolerance and temperature range specifications meet the most stringent requirements of your application.
