Key Parameters

Substitute Part Grouping Explanation

Substitution of the RP164PJ3R0CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 3 Ohm
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: Isolated
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals
• Number of pins: 8
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Height - Seated (Max): 0.024" (0.60mm)

Allowable Variation:

• Power Per Element: The substitute part may exceed the original specification (62.5mW minimum requirement). Higher power rating provides enhanced thermal margin without affecting circuit compatibility.

The RAVF164DJT3R00 from Stackpole Electronics Inc satisfies all mandatory parameters and exceeds the power per element specification, qualifying as a direct substitute.

Engineering Selection Recommendations

The RAVF164DJT3R00 is the qualified substitute for the obsolete RP164PJ3R0CS based on the following engineering criteria:

Product Status Alignment: The RP164PJ3R0CS is classified as obsolete, creating supply chain risk. The RAVF164DJT3R00 maintains active product status, ensuring long-term availability and manufacturing support.

Compliance & Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental regulatory requirements. The RAVF164DJT3R00 carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

Electrical & Mechanical Equivalence: All critical electrical parameters—resistance value, tolerance, temperature coefficient, and operating temperature range—are identical. Physical dimensions, pin configuration, and package geometry are fully compatible, enabling direct board-level substitution without layout modifications.

Power Rating Enhancement: The RAVF164DJT3R00 provides 100mW power per element compared to the original 62.5mW specification. This increased thermal capacity represents a design margin improvement and does not introduce compatibility issues in circuits designed for the lower power rating.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT3R00 be used as a direct replacement for the RP164PJ3R0CS without circuit modifications?

A: Yes. The RAVF164DJT3R00 is electrically and mechanically equivalent across all critical parameters. Identical resistance value, tolerance, temperature coefficient, operating temperature range, and package configuration enable direct substitution. No circuit design changes are required.

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 in the RAVF164DJT3R00 provides additional thermal margin. Circuits designed for the original 62.5mW specification operate within the substitute's thermal envelope with enhanced reliability. The higher rating does not affect electrical performance or compatibility.

Q: Are there packaging differences between the two parts?

A: No. Both parts use identical 1206 (3216 Metric) surface mount packages with convex, long side terminals. Physical dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm) and maximum seated height (0.024" / 0.60mm) are identical, ensuring compatibility with existing PCB layouts and assembly processes.

Q: What compliance certifications apply to the substitute part?

A: The RAVF164DJT3R00 is ROHS3 compliant and REACH unaffected. Additionally, it carries AEC-Q200 automotive qualification, meeting automotive industry reliability standards. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: Why is the original RP164PJ3R0CS classified as obsolete?

A: Obsolescence reflects Samsung Electro-Mechanics' discontinuation of this product line. The RAVF164DJT3R00 from Stackpole Electronics Inc provides functional equivalence with active manufacturing status, ensuring continued supply availability for new designs and production support.

Q: Are there any temperature or environmental operating differences?

A: No. Both parts operate across the identical temperature range of -55°C to 155°C with matching ±200ppm/°C temperature coefficient. Environmental compliance and moisture sensitivity classifications are equivalent.
