Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ823CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 82kΩ
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: Isolated
• Package designation: 1206 (3216 Metric), Convex, Long Side Terminals
• Number of pins: 8
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Mounting type: Surface Mount

Allowable Variation:

• Power per element: Substitute must equal or exceed 62.5mW minimum
• Product status: Active status preferred for long-term availability

The RAVF164DJT82K0 from Stackpole Electronics Inc qualifies as a direct substitute, meeting all mandatory parameters while providing enhanced power rating (100mW per element) and active product status.

Engineering Selection Recommendations

Primary Substitute: RAVF164DJT82K0

The RAVF164DJT82K0 is the qualified equivalent for RP164PJ823CS replacement. Selection rationale:

1. Electrical Equivalence: All critical electrical parameters match or exceed the original specification. The 100mW power per element rating provides 60% additional power dissipation margin compared to the 62.5mW original specification, enhancing thermal performance and reliability margin.

2. Physical Compatibility: Identical package dimensions (1206/3216 Metric), terminal configuration (convex, long-side), and pin count (8) ensure direct PCB footprint compatibility without layout modification.

3. Compliance Alignment: Both components maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity classification (MSL 1), ensuring regulatory and environmental compatibility.

4. Product Status: The substitute maintains active product status with Stackpole Electronics Inc, providing long-term procurement availability and supply chain continuity compared to the obsolete original part.

5. Thermal Performance: Identical temperature coefficient (±200ppm/°C) and operating range (-55°C to 155°C) ensure thermal behavior consistency across the application temperature envelope.

Frequently Asked Questions (FAQ)

Q: Can RAVF164DJT82K0 be used as a direct replacement for RP164PJ823CS without circuit modification?

A: Yes. The substitute part maintains identical electrical specifications (82kΩ ±5%, ±200ppm/°C, -55°C to 155°C operating range) and physical package configuration (1206 Convex, 8-pin). No circuit design changes are required. The higher power rating (100mW vs. 62.5mW per element) provides additional thermal margin without affecting circuit function.

Q: What is the significance of the "Isolated" circuit type designation?

A: Isolated circuit type indicates that the four resistor elements within the array are electrically independent with no internal connections between them. This configuration allows each resistor to function independently in the circuit. Substitutes must maintain this isolation characteristic to preserve circuit functionality.

Q: Are there any packaging differences between the main part and substitute?

A: Both components use identical 1206 (3216 Metric) surface mount packages with convex, long-side terminals. Physical dimensions are 0.126" L x 0.063" W (3.20mm x 1.60mm). Maximum seated heights are equivalent (0.61mm vs. 0.60mm), representing negligible variation within manufacturing tolerance. PCB assembly processes and equipment settings require no adjustment.

Q: Why is product status (Obsolete vs. Active) important for component selection?

A: Active product status indicates ongoing manufacturing and supplier support. The RAVF164DJT82K0 active status ensures continued availability for future procurement, design revisions, and production runs. Obsolete parts face eventual supply discontinuation, making active equivalents preferable for long-term design sustainability.

Q: Does the higher power rating of RAVF164DJT82K0 (100mW vs. 62.5mW) affect circuit behavior?

A: No. Power rating represents the maximum power dissipation capability per resistor element. A higher rating does not alter resistance value, tolerance, temperature coefficient, or electrical performance. It only indicates greater thermal capacity, which provides design margin and improved reliability under identical operating conditions.

Q: Are compliance certifications identical between the two parts?

A: Yes. Both RP164PJ823CS and RAVF164DJT82K0 maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity classification. Regulatory and environmental requirements are fully aligned, eliminating compliance concerns for substitution.
