Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ3R9CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 3.9 Ohm
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit configuration: Isolated
• Number of pins: 8
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Operating temperature range: -55°C ~ 155°C minimum
• Mounting type: Surface Mount

Allowable Variation Parameters:

• Power per element: Substitute must equal or exceed 62.5mW
• Temperature coefficient: Substitute may differ from ±300ppm/°C
• Product status: Active or Obsolete
• Packaging format: May differ (Tape & Reel vs. other formats)

The RAVF164DJT3R90 from Stackpole Electronics Inc qualifies as a direct substitute based on matching all mandatory parameters while providing enhanced power dissipation capability (100mW per element versus 62.5mW) and improved temperature stability (±200ppm/°C versus ±300ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

The RAVF164DJT3R90 is a qualified substitute for the RP164PJ3R9CS based on the following engineering criteria:

Functional Equivalence: Both components share identical electrical specifications for resistance value, tolerance, circuit isolation, and pin configuration. The 1206 package geometry and surface mount characteristics ensure mechanical and electrical compatibility in existing PCB layouts without design modification.

Compliance Status: Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), satisfying environmental and reliability requirements. The RAVF164DJT3R90 carries AEC-Q200 automotive qualification, indicating enhanced reliability validation.

Performance Enhancement: The substitute provides superior performance margins through increased power dissipation (100mW versus 62.5mW per element) and tighter temperature coefficient specification (±200ppm/°C versus ±300ppm/°C), resulting in improved thermal stability and reduced drift over the operating temperature range.

Supply Continuity: The RP164PJ3R9CS is obsolete with limited inventory availability. The RAVF164DJT3R90 maintains active production status, ensuring long-term procurement availability and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT3R90 be used as a direct replacement for the RP164PJ3R9CS without PCB modifications?

A: Yes. Both components utilize identical 1206 (3216 Metric) package geometry with convex, long side terminals and 8-pin configuration. No PCB layout changes are required for mechanical or electrical compatibility.

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

A: The increased power per element rating provides additional thermal margin and allows the component to operate safely at higher current levels without exceeding temperature limits. This represents an enhancement over the original specification and does not create compatibility issues.

Q: Does the improved temperature coefficient (±200ppm/°C) of the substitute affect circuit performance?

A: The tighter temperature coefficient of the RAVF164DJT3R90 results in reduced resistance drift across the -55°C to 155°C operating range. This improves circuit stability and accuracy, representing a performance benefit with no negative impact on compatibility.

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

A: Both parts are ROHS3 compliant with MSL 1 rating. The RAVF164DJT3R90 additionally carries AEC-Q200 automotive qualification, indicating validation for automotive applications. This certification does not restrict use in non-automotive applications.

Q: What packaging formats are available for the RAVF164DJT3R90?

A: The RAVF164DJT3R90 is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement process, as the original RP164PJ3R9CS packaging format was not specified in available documentation.

Q: Is the RAVF164DJT3R90 suitable for high-reliability applications?

A: Yes. The AEC-Q200 qualification of the RAVF164DJT3R90 indicates compliance with automotive reliability standards, including thermal cycling, vibration, and humidity testing. This qualification supports use in demanding industrial and automotive environments.
