Engineering Selection Recommendations

Primary Substitute: RAVF164DJT8R20

The RAVF164DJT8R20 is the qualified substitute for the obsolete RP164PJ8R2CS. Selection rationale is based on the following engineering factors:

Compliance & Certification:

• Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1)
• RAVF164DJT8R20 carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components
• Both parts are classified as REACH Unaffected and carry EAR99 ECCN designation

Product Status & Availability:

• RP164PJ8R2CS is obsolete, creating supply chain risk
• RAVF164DJT8R20 maintains active product status, ensuring long-term procurement availability and manufacturing continuity

Electrical Performance:

• Power per element rating of 100mW in the substitute exceeds the original 62.5mW specification, providing thermal margin in applications
• Temperature coefficient of ±200ppm/°C in the substitute is superior to the original ±300ppm/°C, delivering improved temperature stability
• All other electrical parameters (resistance, tolerance, circuit configuration) are identical

Physical & Mechanical Compatibility:

• Identical package dimensions and pin configuration enable direct PCB footprint compatibility
• Seated height difference of 0.01mm (0.61mm vs 0.60mm) is negligible for assembly and clearance considerations
• Surface mount configuration and convex long-side terminal design are identical

The RAVF164DJT8R20 is suitable for direct replacement in all applications where the RP164PJ8R2CS was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT8R20 be used as a direct replacement for the RP164PJ8R2CS?

A: Yes. The RAVF164DJT8R20 is a direct functional substitute. Both parts share identical resistance values (8.2 Ohm), tolerance (±5%), element count (4), circuit configuration (isolated), package type (1206 convex), pin count (8), and operating temperature range (-55°C to 155°C). Physical dimensions and mounting characteristics are identical, enabling direct PCB footprint compatibility without design modification.

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

A: The primary differences are: (1) Product status—RP164PJ8R2CS is obsolete while RAVF164DJT8R20 is active; (2) Power per element—100mW vs 62.5mW; (3) Temperature coefficient—±200ppm/°C vs ±300ppm/°C; (4) Manufacturer—Stackpole vs Samsung; (5) Automotive qualification—RAVF164DJT8R20 carries AEC-Q200 certification. The substitute offers improved electrical performance and long-term availability.

Q: Are there any package or pinout differences?

A: No. Both parts use the 1206 (3216 Metric) package with convex long-side terminals and 8-pin configuration. Seated height differs by only 0.01mm (0.61mm vs 0.60mm), which is negligible for PCB assembly and clearance. Direct footprint compatibility is confirmed.

Q: Does the higher power rating of the substitute affect circuit operation?

A: No. A higher power per element rating (100mW vs 62.5mW) indicates the substitute can dissipate more power without exceeding temperature limits. This provides additional thermal margin and does not alter circuit behavior when operating within the original design specifications.

Q: Is the improved temperature coefficient of the substitute beneficial?

A: Yes. The RAVF164DJT8R20 temperature coefficient of ±200ppm/°C is superior to the original ±300ppm/°C specification. This means resistance values remain more stable across the operating temperature range, improving circuit performance and reducing temperature-related drift.

Q: What is the significance of AEC-Q200 qualification on the substitute?

A: AEC-Q200 is an automotive industry qualification standard for passive components. The RAVF164DJT8R20 carries this certification, indicating it meets stringent automotive reliability and quality requirements. This certification is beneficial for applications requiring automotive-grade components but does not restrict use in non-automotive applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the RP164PJ8R2CS and RAVF164DJT8R20 are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What should be considered when transitioning from the obsolete part to the substitute?

A: Transition considerations include: (1) Confirming PCB footprint compatibility (confirmed—identical dimensions); (2) Verifying circuit performance with improved temperature coefficient (beneficial); (3) Ensuring procurement of the substitute from authorized distributors; (4) Updating component specifications and bill of materials documentation. No circuit redesign is required.
