Package: 1206 (3216 Metric) with 8 pins
Mounting type: Surface mount
Pin count and terminal configuration: Long side terminals

Performance Parameters Affecting Substitution:

Tolerance: ±5% or better (tighter tolerances are acceptable upgrades)

Engineering Selection Recommendations

Direct Equivalent (Active Status):

The YC164-JR-0720KL from YAGEO provides direct functional equivalence to the RP164PJ203CS. Both parts share identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The YC164-JR-0720KL carries active product status with AEC-Q200 automotive qualification, ensuring continued availability and supply chain reliability. This part is suitable for direct replacement in existing designs without circuit modification.

Upgrade Options (Enhanced Performance):

The ACASA2002E2002P100 from Vishay Beyschlag/Draloric/BC Components represents a precision upgrade with ±0.25% tolerance, ±25ppm/°C temperature coefficient, and 100mW power per element. This part is designated for voltage divider applications requiring TCR matching and delivers superior stability characteristics. Operating temperature range is limited to -55°C to 125°C, which is acceptable for applications not requiring the full 155°C upper limit of the original part.

The ACASA200222002P100 offers professional-grade performance with ±0.5% tolerance and ±50ppm/°C temperature coefficient at 100mW power per element, providing a mid-tier upgrade path with the same temperature range limitation.

The RAVF164DFT20K0 from Stackpole Electronics Inc maintains the full -55°C to 155°C operating range with ±1% tolerance and 100mW power per element. This part carries AEC-Q200 automotive qualification and is suitable for applications requiring extended temperature operation without precision matching requirements.

Not Recommended for New Designs:

The ACASA2002E2002P1AT, while offering precision specifications and automotive qualification, carries a "Not For New Designs" status and should be reserved for legacy system maintenance only.

Frequently Asked Questions (FAQ)

Q: Can the YC164-JR-0720KL be used as a direct replacement for the RP164PJ203CS?

A: Yes. The YC164-JR-0720KL is a direct equivalent with matching resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Both parts use identical 1206 package configuration with 8 pins and long side terminals. The YC164-JR-0720KL is active and widely available.

Q: What is the difference between the ACASA2002E2002P100 and ACASA200222002P100?

A: Both are Vishay precision upgrades with enhanced power ratings (100mW vs. 62.5mW). The ACASA2002E2002P100 provides tighter tolerance (±0.25% vs. ±0.5%) and superior temperature coefficient (±25ppm/°C vs. ±50ppm/°C). The ACASA2002E2002P100 includes resistor matching ratio of ±0.05% and resistor-ratio-drift specification of ±7.5ppm/°C, making it suitable for precision voltage divider applications.

Q: Are there temperature range limitations with the upgrade options?

A: The ACASA2002E2002P100 and ACASA200222002P100 operate to 125°C maximum, which is 30°C lower than the original RP164PJ203CS specification of 155°C. The YC164-JR-0720KL and RAVF164DFT20K0 maintain the full -55°C to 155°C range. Verify application temperature requirements before selection.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance profile of the original RP164PJ203CS.

Q: Which substitute part is recommended for automotive applications?

A: The YC164-JR-0720KL, ACASA2002E2002P1AT, and RAVF164DFT20K0 all carry AEC-Q200 automotive qualification. The YC164-JR-0720KL is the preferred choice for new automotive designs due to active product status and direct specification equivalence.

Q: Can precision upgrade parts be used in applications designed for ±5% tolerance?

A: Yes. Parts with tighter tolerance specifications (±0.25%, ±0.5%, ±1%) are functionally compatible with circuits designed for ±5% tolerance. The tighter tolerance represents improved performance and does not create incompatibility. However, verify that enhanced temperature coefficient stability does not introduce unintended circuit behavior changes in temperature-sensitive applications.

Q: What is the physical dimension difference between the main part and substitutes?

A: All parts use the 1206 (3216 Metric) package. The RP164PJ203CS and RAVF164DFT20K0 share identical dimensions: 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.024" (0.60mm) maximum seated height. The Vishay precision parts (ACASA series) have slightly different dimensions: 0.126" L × 0.059" W (3.20mm × 1.50mm) with 0.022" (0.55mm) maximum seated height. These dimensional variations remain within standard 1206 package tolerances and do not affect PCB footprint compatibility.
