Substitute Part Grouping Explanation

Substitution of the RP164PJ433CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Resistance value: 43kΩ
• 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
• Physical dimensions: 0.126" L × 0.063" W (3.20mm × 1.60mm)

Allowable Variation:

• Power per element: Substitute parts may exceed the original specification (62.5mW minimum required)
• Product status: Active parts are preferred over obsolete classifications
• Packaging format: Tape & Reel acceptable for production environments

The RAVF164DJT43K0 from Stackpole Electronics Inc satisfies all mandatory matching criteria while providing enhanced power dissipation capability (100mW per element) and active product status.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT43K0 be used as a direct replacement for the RP164PJ433CS in existing designs?

A: Yes. The RAVF164DJT43K0 is electrically and mechanically equivalent across all critical parameters. Identical resistance value, tolerance, temperature coefficient, operating range, package type, and pin configuration enable direct substitution without circuit redesign or PCB modification.

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

A: The increased power per element rating on the RAVF164DJT43K0 indicates enhanced thermal dissipation capability. This does not alter electrical performance in applications designed for the original 62.5mW specification; it provides additional thermal margin and may extend component life in high-current applications.

Q: Are there packaging differences between these parts?

A: Both parts use identical 1206 (3216 Metric) surface mount packages with convex, long side terminals. The Stackpole part is supplied in Tape & Reel format, standard for production environments. Physical dimensions and height specifications are equivalent.

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

A: No. AEC-Q200 qualification indicates automotive-grade reliability testing and is not restrictive. The part functions identically in industrial, consumer, and other non-automotive applications.

Q: What is the impact of the ±200ppm/°C temperature coefficient across the operating range?

A: The temperature coefficient applies uniformly to both parts across the -55°C to 155°C operating range. Resistance drift is identical between the RP164PJ433CS and RAVF164DJT43K0, ensuring equivalent performance in temperature-sensitive applications.

Q: Are there any electrical performance differences in isolated circuit configuration?

A: No. Both parts implement identical isolated circuit topology with four independent resistor elements. Electrical isolation between elements is equivalent.
