Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT1R20 be used as a direct replacement for the RP164PJ1R2CS without PCB modifications?

A: Yes. Both components share identical package designation (1206 with convex, long side terminals), pin count (8), and physical dimensions (0.126" L x 0.063" W). No PCB layout changes are required.

Q: What are the key electrical differences between these two parts?

A: The primary differences are power rating and temperature coefficient. The RAVF164DJT1R20 provides 100mW per element versus 62.5mW for the RP164PJ1R2CS, and maintains a tighter temperature coefficient of ±200ppm/°C versus ±300ppm/°C. Both maintain identical 1.2 Ohm resistance and ±5% tolerance.

Q: Why is the RP164PJ1R2CS listed as obsolete?

A: The RP164PJ1R2CS is classified as obsolete by Samsung Electro-Mechanics. The RAVF164DJT1R20 from Stackpole Electronics Inc is an active product with equivalent specifications and superior performance characteristics.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and carry MSL 1 (unlimited) moisture sensitivity rating. The RAVF164DJT1R20 additionally carries AEC-Q200 automotive qualification, which is not specified for the RP164PJ1R2CS.
