Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ2R2CS is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.2 Ohm
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit configuration: Isolated
• Number of pins: 8
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Mounting type: Surface Mount
• Operating temperature range: -55°C ~ 155°C

Allowable Parameter Variations:

• Power per element: Substitute must equal or exceed 62.5mW
• Temperature coefficient: Substitute must equal or be superior (lower absolute value)
• RoHS and MSL compliance: Must maintain or exceed compliance level

The RAVF164DJT2R20 from Stackpole Electronics Inc satisfies all mandatory parameters and demonstrates superior performance in power rating (100mW vs 62.5mW) and temperature coefficient stability (±200ppm/°C vs ±300ppm/°C).

Engineering Selection Recommendations

The RAVF164DJT2R20 is a direct functional substitute for the obsolete RP164PJ2R2CS. Selection is based on the following engineering criteria:

Product Status Alignment: The RP164PJ2R2CS is classified as obsolete, creating supply chain risk. The RAVF164DJT2R20 maintains active production status, ensuring long-term availability and supply continuity.

Compliance Certification: Both components maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating. The RAVF164DJT2R20 carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

Performance Enhancement: The substitute part delivers superior electrical performance through increased power dissipation capability (100mW vs 62.5mW per element) and improved temperature stability (±200ppm/°C vs ±300ppm/°C). These enhancements provide design margin without introducing compatibility constraints.

Physical and Electrical Equivalence: Identical package geometry, pin configuration, resistance value, tolerance, and operating temperature range ensure direct PCB-level compatibility and circuit performance equivalence.

Frequently Asked Questions (FAQ)

Q: Can RAVF164DJT2R20 be used as a direct replacement for RP164PJ2R2CS in existing designs?

A: Yes. The RAVF164DJT2R20 is electrically and mechanically equivalent. Identical resistance value (2.2 Ohm), tolerance (±5%), package type (1206 Convex), pin count (8), and operating temperature range (-55°C ~ 155°C) ensure direct substitution without circuit modification. The substitute's superior power rating and temperature coefficient provide additional design margin.

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

A: The primary differences are: (1) Product status—RP164PJ2R2CS is obsolete while RAVF164DJT2R20 is active; (2) Power per element—100mW vs 62.5mW; (3) Temperature coefficient—±200ppm/°C vs ±300ppm/°C; (4) Manufacturer—Stackpole vs Samsung; (5) Packaging—Tape & Reel vs standard packaging; (6) Automotive qualification—RAVF164DJT2R20 carries AEC-Q200 certification.

Q: Are there any height or dimensional concerns when substituting?

A: No. Both components share identical length and width dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm). Maximum seated heights are functionally equivalent (0.024" / 0.61mm vs 0.024" / 0.60mm), presenting no PCB assembly or clearance issues.

Q: Does the higher power rating of RAVF164DJT2R20 affect circuit operation?

A: No. Higher power rating indicates greater thermal capacity and does not alter electrical behavior. The component will operate identically to the original part under identical circuit conditions. The increased power capability provides design margin for thermal stress scenarios.

Q: Is the AEC-Q200 qualification on RAVF164DJT2R20 relevant for non-automotive applications?

A: AEC-Q200 qualification indicates enhanced reliability testing and quality assurance. While not required for non-automotive applications, this certification provides additional confidence in component reliability and consistency across manufacturing batches.

Q: What is the significance of the ±200ppm/°C temperature coefficient improvement?

A: Lower temperature coefficient indicates superior resistance stability across the operating temperature range (-55°C ~ 155°C). The RAVF164DJT2R20's ±200ppm/°C specification provides tighter resistance tolerance maintenance compared to the original ±300ppm/°C, reducing circuit performance drift in temperature-sensitive applications.

Q: Can these parts be mixed in the same production batch?

A: Yes. Both components meet identical electrical and mechanical specifications for the 2.2 Ohm 4-resistor isolated network array in 1206 package. Identical RoHS3 compliance and MSL Level 1 rating ensure compatibility in manufacturing processes and supply chain handling.
