Key Parameters

Substitute Part Grouping Explanation

Substitution of the RP164PJ120CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 12 Ohm
• Tolerance: ±5%
• Circuit type: Isolated
• Number of resistors: 4
• Number of pins: 8
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Mounting type: Surface Mount

Allowable Variation:

• Power per element: The substitute may exceed the original specification (62.5mW minimum required)
• Product status: Active substitutes are acceptable for obsolete parts
• Packaging format: Tape & Reel (TR) is compatible with original packaging requirements

The RAVF164DJT12R0 from Stackpole Electronics Inc meets all mandatory matching parameters and qualifies as a direct substitute.

Engineering Selection Recommendations

The RAVF164DJT12R0 is a qualified substitute for the RP164PJ120CS based on the following engineering criteria:

Compliance & Certification Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in existing designs. The substitute carries AEC-Q200 automotive qualification, which provides additional reliability assurance beyond the original part specification.

Product Status Advantage: The RP164PJ120CS is classified as obsolete, creating supply chain risk. The RAVF164DJT12R0 maintains active product status with documented inventory availability, ensuring long-term procurement viability.

Electrical Performance: The substitute component exceeds the original power rating (100mW vs. 62.5mW per element), providing enhanced thermal margin without altering circuit behavior. All other electrical parameters—resistance, tolerance, temperature coefficient, and operating range—are identical.

Physical & Mechanical Compatibility: Dimensional specifications are equivalent within manufacturing tolerances. Both components use identical 1206 (3216 Metric) convex package geometry with long side terminals, ensuring direct PCB footprint compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT12R0 be used as a direct replacement for the RP164PJ120CS without circuit modification?

A: Yes. The substitute meets all mandatory electrical and mechanical parameters. Identical resistance value, tolerance, circuit isolation, pin configuration, and package geometry ensure direct compatibility. No circuit redesign is required.

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

A: The increased power rating provides additional thermal headroom during operation. This does not alter circuit function but reduces thermal stress on the component, potentially extending operational life in thermally demanding applications.

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

A: Both components are ROHS3 compliant and REACH unaffected. The substitute carries additional AEC-Q200 automotive qualification, which is a superset of the original part's compliance profile and does not create incompatibility.

Q: Does the packaging format difference (original vs. Tape & Reel) affect compatibility?

A: No. Tape & Reel (TR) packaging is a standard surface mount delivery format compatible with automated assembly processes. The component itself is identical; only the delivery method differs.

Q: What is the physical dimension tolerance between the two parts?

A: Both components conform to the 1206 (3216 Metric) standard. Height specifications are equivalent (0.024" maximum, with substitute at 0.60mm vs. original at 0.61mm), representing negligible variation within manufacturing tolerance and PCB assembly clearance requirements.

Q: Is the ±200ppm/°C temperature coefficient critical for substitution?

A: Yes. Temperature coefficient directly affects resistor value stability across the operating range. Both parts specify identical ±200ppm/°C performance, ensuring equivalent thermal behavior in temperature-sensitive applications.

Q: Can the RAVF164DJT12R0 be used in automotive applications?

A: Yes. The substitute carries AEC-Q200 qualification, which certifies suitability for automotive environments. The original RP164PJ120CS does not specify automotive qualification, making the substitute suitable for a broader application range.
