Key Parameters

Substitute Part Grouping Explanation

Substitution of the RP164PJ430CS is determined by the following critical electrical and mechanical parameters that must match or exceed the original specifications:

Required Matching Parameters:

• Resistance value: 43 Ohms
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: 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
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)

Acceptable Parameter Variation:

• Power per element may exceed the original 62.5mW specification, as higher power ratings provide design margin without circuit impact
• Regulatory compliance certifications (RoHS, REACH) must be maintained at or above the original level

Parameter Comparison

Engineering Selection Recommendations

The RAVF164DJT43R0 manufactured by Stackpole Electronics Inc. is a direct functional equivalent to the obsolete RP164PJ430CS. All critical electrical parameters match precisely: 43 Ohm resistance, ±5% tolerance, ±200ppm/°C temperature coefficient, and -55°C to 155°C operating range. The package, pinout, and mounting specifications are identical.

The RAVF164DJT43R0 offers superior product status as an active component, ensuring long-term supply availability. The increased power rating per element (100mW versus 62.5mW) provides additional design margin without altering circuit behavior. Both components maintain full RoHS3 and REACH compliance with equivalent moisture sensitivity ratings.

For applications requiring automotive qualification, the RAVF164DJT43R0 carries AEC-Q200 certification, providing formal automotive-grade reliability assurance. This substitution requires no circuit modifications or board redesign.

Frequently Asked Questions (FAQ)

Q: Are the RP164PJ430CS and RAVF164DJT43R0 pin-compatible? A: Yes. Both components feature 8-pin configurations in identical 1206 (3216 Metric) packages with convex, long side terminals. Direct PCB footprint compatibility is assured.

Q: Can the RAVF164DJT43R0 be used in all applications designed for the RP164PJ430CS? A: Yes. The RAVF164DJT43R0 meets or exceeds all electrical specifications of the original component. The higher power rating per element (100mW) is a design improvement that maintains circuit functionality across all operating conditions.

Q: What is the impact of the different height specifications (0.61mm vs. 0.60mm)? A: The 0.01mm difference falls within standard PCB assembly tolerances and produces no practical impact on board clearance, stacking, or mechanical assembly. Both components conform to the same package specification.

Q: Is the RAVF164DJT43R0 certified for automotive applications? A: Yes. The RAVF164DJT43R0 carries AEC-Q200 automotive qualification. The original RP164PJ430CS does not explicitly list automotive certification in the provided specifications.

Q: How does the different packaging format affect part selection? A: The RP164PJ430CS is listed with unspecified packaging, while the RAVF164DJT43R0 is supplied in Tape & Reel (TR) format. This difference affects only handling and storage; the component itself is identical. Tape & Reel packaging is the standard format for high-volume production environments.

Q: Are there any performance differences between these components? A: No. All critical performance parameters are identical: resistance value, tolerance, temperature coefficient, temperature range, and circuit isolation topology. The increased power dissipation capability of the RAVF164DJT43R0 represents a design enhancement rather than a performance difference.
