Substitute Part Grouping Explanation

Substitute parts for the RGC0805FTC82K5 are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 82.5 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (physical and electrical compatibility)
• Composition: Thick Film (material consistency)
• Temperature Coefficient: ±50ppm/°C (thermal stability equivalence)
• Operating Temperature Range: -55°C ~ 155°C (environmental compatibility)

Allowable Variations:

• Tolerance: May be equal to or tighter than ±1% (±0.1% or ±0.5% acceptable)
• Power Rating: May be equal to or greater than 0.125W (0.25W acceptable)
• Manufacturer: Different manufacturer permitted if all parameters align
• Additional Features: Automotive AEC-Q200 certification and pulse withstanding capability are enhancements that do not disqualify substitution

The two substitute parts listed (ERJ-PB6B8252V and ERJ-PB6D8252V) meet all mandatory matching criteria while offering improved tolerance and higher power ratings, making them suitable direct replacements.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified replacements for the RGC0805FTC82K5 based on electrical and mechanical compatibility. Selection between alternatives should be based on the following factors:

ERJ-PB6B8252V (±0.1% Tolerance): This part offers the tightest tolerance specification and is suitable for applications requiring precision resistor networks or high-accuracy signal conditioning circuits. The automotive AEC-Q200 certification indicates suitability for automotive and industrial environments with stringent reliability requirements.

ERJ-PB6D8252V (±0.5% Tolerance): This part provides a balance between tolerance performance and cost-effectiveness. The ±0.5% tolerance is tighter than the original ±1% specification while maintaining broader availability. Automotive AEC-Q200 certification and pulse withstanding capability make this part suitable for high-reliability applications.

Both substitute parts feature doubled power rating (0.25W versus 0.125W), providing additional thermal margin in applications with variable load conditions. The marginal increase in seated height (0.028" versus 0.024") is within typical PCB design tolerances for 0805 components and does not present assembly or clearance concerns.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PB6B8252V and ERJ-PB6D8252V be used interchangeably with RGC0805FTC82K5?

A: Yes. Both parts share identical resistance values, package dimensions, and operating temperature ranges. The primary differences are tolerance specifications (tighter on substitutes) and power ratings (higher on substitutes), which make them functionally compatible and electrically superior for direct replacement applications.

Q: What is the significance of the tolerance difference between ±1% and ±0.1% or ±0.5%?

A: Tolerance defines the maximum deviation of actual resistance from the nominal 82.5 kOhms value. The original part allows ±825 Ohms deviation, while ERJ-PB6B8252V limits deviation to ±82.5 Ohms and ERJ-PB6D8252V to ±412.5 Ohms. Tighter tolerance is beneficial in precision circuits but not required for general-purpose applications.

Q: Does the increased power rating of substitute parts affect circuit performance?

A: No. Power rating indicates maximum power dissipation capability. Using a part with higher power rating does not change circuit behavior; it only provides additional thermal headroom. The substitute parts will dissipate identical power to the original part in the same circuit.

Q: Are there physical compatibility concerns with the increased seated height?

A: No. The increase from 0.024" to 0.028" maximum seated height is within standard PCB design tolerances for 0805 components. This marginal difference does not affect assembly, soldering, or clearance in typical applications.

Q: What does AEC-Q200 certification indicate?

A: AEC-Q200 is an automotive industry standard qualification for passive components. It certifies that the part meets stringent reliability, temperature cycling, and performance requirements for automotive applications. This certification is an enhancement and does not restrict use in non-automotive applications.

Q: Are all parts ROHS3 compliant?

A: Yes. The main part and both substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
