Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ181CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 180 Ohm
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit configuration: Isolated
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Number of pins: 8
• Mounting type: Surface Mount

Allowable Variation:

• Power per element: Substitute parts may exceed the 62.5mW specification of the main part, provided the higher power rating does not introduce thermal or reliability concerns in the application circuit.

The RAVF164DJT180R from Stackpole Electronics Inc meets all mandatory parameters and exceeds the power specification at 100mW per element, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The RAVF164DJT180R is a direct functional substitute for the obsolete RP164PJ181CS. Both components share identical electrical specifications for resistance, tolerance, temperature coefficient, and operating temperature range. The substitute part maintains full compatibility with the 1206 package footprint and pin configuration.

The RAVF164DJT180R offers the following advantages:

• Active Product Status: Currently manufactured and available through distribution channels, ensuring long-term supply continuity.
• Enhanced Power Rating: The 100mW per element specification exceeds the original 62.5mW rating, providing additional thermal margin in applications where power dissipation is a design consideration.
• Automotive Qualification: AEC-Q200 certification qualifies this component for automotive applications, extending its use beyond the original part's scope.
• Regulatory Compliance: ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Physical dimensions and height specifications are equivalent, confirming PCB layout and assembly compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT180R be used as a direct replacement for the RP164PJ181CS without PCB modifications?

A: Yes. Both components share identical package dimensions (1206 / 3216 Metric), pin count (8), pin configuration (Convex, Long Side Terminals), and mounting type (Surface Mount). No PCB layout changes are required.

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

A: The substitute part's 100mW per element specification provides additional thermal headroom. This higher rating does not affect electrical performance in circuits designed for the original 62.5mW specification. The substitute will operate at lower junction temperatures under identical load conditions.

Q: Are the electrical characteristics identical between the two parts?

A: Yes. Both parts specify 180 Ohm resistance, ±5% tolerance, ±200ppm/°C temperature coefficient, and -55°C to 155°C operating temperature range. Electrical performance is equivalent.

Q: Why is the RAVF164DJT180R classified as Active while the RP164PJ181CS is Obsolete?

A: The RP164PJ181CS has been discontinued by Samsung Electro-Mechanics. The RAVF164DJT180R remains in active production by Stackpole Electronics Inc, ensuring availability for new designs and production support.

Q: Does the AEC-Q200 qualification of the substitute part affect its use in non-automotive applications?

A: No. AEC-Q200 qualification indicates the part meets automotive reliability standards. This certification does not restrict use in other applications and represents an additional quality assurance measure.

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

A: Both parts are ROHS3 compliant and REACH unaffected. Regulatory status is equivalent. The substitute part's automotive qualification (AEC-Q200) represents an additional certification not present in the original part.
