Key Parameters

Substitute Part Grouping Explanation

Substitution of the RP164PJ4R7CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 4.7 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
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Operating temperature range: -55°C ~ 155°C

Allowable Parameter Variations:

• Power per element: May exceed the original 62.5mW specification
• Temperature coefficient: May be equal to or better (lower absolute value) than ±300ppm/°C
• Product status: Active status preferred for long-term availability
• Compliance certifications: Must maintain ROHS3 compliance and MSL 1 rating

The RAVF164DJT4R70 from Stackpole Electronics Inc qualifies as a direct substitute based on these criteria.

The temperature coefficient of ±200ppm/°C is superior to the original ±300ppm/°C, indicating better frequency stability and temperature performance.

3. Product Status: The RAVF164DJT4R70 maintains active manufacturing status, ensuring long-term availability and supply chain continuity.

4. Compliance Alignment: Both components maintain ROHS3 compliance and MSL 1 rating, meeting environmental and moisture sensitivity requirements.

5. Physical Compatibility: Identical package dimensions, pin configuration, and mounting type ensure direct PCB compatibility without layout modifications.

6. Automotive Qualification: The substitute carries AEC-Q200 automotive qualification, extending its applicability to automotive and high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT4R70 be used as a direct replacement for the RP164PJ4R7CS without PCB modifications?

A: Yes. Both components share identical package dimensions (1206/3216 Metric), pin count (8), pin configuration (isolated network), 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?

A: The higher power rating indicates the substitute can dissipate more thermal energy per resistor element. This provides additional design margin and does not create compatibility issues. The substitute will operate within the same temperature range as the original.

Q: Does the improved temperature coefficient (±200ppm/°C vs. ±300ppm/°C) affect circuit performance?

A: The lower temperature coefficient of the substitute indicates superior stability across temperature variations. This is a performance improvement that does not compromise compatibility. Circuits designed for the original specification will operate within acceptable parameters with the substitute.

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

A: Both components are ROHS3 compliant with MSL 1 rating. The substitute additionally carries AEC-Q200 automotive qualification, which is a superset qualification that does not restrict use in non-automotive applications.

Q: Why is the original RP164PJ4R7CS classified as obsolete?

A: Product obsolescence is determined by the manufacturer and typically reflects end-of-life decisions based on market demand and manufacturing priorities. The RAVF164DJT4R70 provides equivalent functionality with enhanced specifications and active manufacturing support.

Q: What packaging options are available for the RAVF164DJT4R70?

A: The substitute is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly operations.

Q: Are there any electrical parameter restrictions when substituting the RAVF164DJT4R70 for the RP164PJ4R7CS?

A: No electrical restrictions apply. The substitute meets or exceeds all critical electrical specifications of the original part. Circuit designs validated for the RP164PJ4R7CS will function correctly with the RAVF164DJT4R70.
