Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ2R7CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.7 Ohm
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: Isolated
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals
• Number of pins: 8
• Mounting type: Surface Mount
• Operating temperature range: -55°C ~ 155°C

Allowable Variation Parameters:

• Power per element: Must meet or exceed 62.5mW
• Temperature coefficient: May vary within acceptable limits for the application
• Product status: Active parts are preferred for obsolete parts

The RAVF164DJT2R70 from Stackpole Electronics Inc satisfies all mandatory matching parameters and exceeds the power rating specification, making it a direct functional equivalent.

Engineering Selection Recommendations

The RAVF164DJT2R70 is a direct functional substitute for the obsolete RP164PJ2R7CS. Selection is based on the following engineering criteria:

Electrical Compatibility: Both parts share identical resistance values, tolerance, circuit topology, and operating temperature range. The RAVF164DJT2R70 provides superior power dissipation capability (100mW versus 62.5mW per element), ensuring adequate thermal margin in applications originally designed for the Samsung part.

Mechanical Compatibility: Package dimensions, pin count, and mounting configuration are identical. Both components use 1206 (3216 Metric) convex, long side terminal packages suitable for standard surface mount assembly processes.

Regulatory Compliance: Both parts are ROHS3 compliant and REACH unaffected. The RAVF164DJT2R70 carries AEC-Q200 automotive qualification, indicating enhanced reliability screening and process controls.

Product Status: The transition from an obsolete Samsung part to an active Stackpole part ensures long-term supply chain availability and manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT2R70 be used as a direct replacement for the RP164PJ2R7CS without circuit modifications?

A: Yes. Both parts are electrically and mechanically identical in all critical parameters. The RAVF164DJT2R70 exceeds the power rating specification, providing additional thermal margin without requiring design changes.

Q: What is the significance of the higher power rating (100mW vs. 62.5mW) on the substitute part?

A: The higher power rating indicates greater thermal dissipation capability. This provides design margin and does not negatively impact circuit performance. Applications designed for 62.5mW operation will function within the thermal limits of the 100mW-rated substitute.

Q: Are the package dimensions identical between the two parts?

A: Yes. Both parts use the 1206 (3216 Metric) package with convex, long side terminals. Physical dimensions are 0.126" L x 0.063" W (3.20mm x 1.60mm), with maximum seated heights of 0.024" (0.61mm and 0.60mm respectively). These dimensions are compatible with standard surface mount assembly equipment and PCB layouts.

Q: What does the AEC-Q200 qualification on the substitute part indicate?

A: AEC-Q200 is an automotive industry qualification standard that certifies component reliability through accelerated life testing and process controls. This qualification enhances confidence in long-term performance and supply chain stability, though it is not required for non-automotive applications.

Q: How do the temperature coefficients differ, and does this affect substitution?

A: The RP164PJ2R7CS has a temperature coefficient of ±300ppm/°C, while the RAVF164DJT2R70 has ±200ppm/°C. The lower coefficient on the substitute part indicates superior temperature stability. This is a favorable characteristic that does not restrict substitution.

Q: Is the RAVF164DJT2R70 available in the same packaging format as the original part?

A: The RAVF164DJT2R70 is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. The RP164PJ2R7CS packaging format was not specified in the original documentation. Both formats are compatible with automated assembly processes.
