Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Compatibility Parameters:

Resistance value: 82 kOhms (exact match required)
Package: 0805 (2012 Metric) (exact match required)
Composition: Thin Film (exact match required)
Operating temperature range: Must encompass or equal -55°C ~ 155°C minimum
RoHS compliance: ROHS3 Compliant (required)
Moisture Sensitivity Level: 1 (Unlimited) (required)

Allowable Variations:

Tolerance: May be equal to or tighter than ±0.5%
Power rating: May be equal to or greater than 0.125W
Temperature coefficient: May be equal to or lower than ±25ppm/°C
Certifications: Additional automotive AEC-Q200 qualification is permissible

All substitute parts listed maintain the 82 kOhms resistance value, 0805 package format, and thin film composition. Variations in tolerance, power rating, and temperature coefficient represent upgrades or alternative specifications within the same functional category.

Engineering Selection Recommendations

Direct Substitutes (Identical Specifications): RT0805BRD0782KL from YAGEO provides identical electrical and mechanical specifications with improved tolerance (±0.1% vs ±0.5%). This part maintains the same power rating, temperature coefficient, and operating range while offering higher precision.

Automotive-Qualified Alternatives: ERA-6AEB823V, ERA-6APB823V, ERA-6ARB823V, and ERA-6ARW823V from Panasonic, along with RG2012P-823-B-T5 from Susumu, carry AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade reliability. ERA-6ARW823V offers the tightest tolerance (±0.05%) and lowest temperature coefficient (±10ppm/°C) among Panasonic options.

Enhanced Power Rating Option: TNPW080582K0BEEA from Vishay Dale provides double the power rating (0.26W vs 0.125W) with extended operating temperature range (-55°C ~ 175°C vs -55°C ~ 155°C). This part includes anti-sulfur and moisture-resistant features with AEC-Q200 qualification.

Matched Tolerance Alternative: RNCF0805DTE82K0 from Stackpole Electronics maintains the original ±0.5% tolerance while providing double the power rating (0.25W) and AEC-Q200 qualification.

All listed substitutes maintain ROHS3 compliance and MSL Level 1 rating.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with tighter tolerance than the original? A: Yes. Parts with tolerance specifications tighter than ±0.5% (such as ±0.1% or ±0.05%) are direct functional upgrades and maintain full compatibility. Tighter tolerance improves circuit accuracy without introducing incompatibility.

Q: What is the difference between automotive-qualified and non-automotive parts? A: Automotive-qualified parts (AEC-Q200) undergo additional reliability testing and qualification procedures required for automotive applications. Non-automotive parts (such as RT0805DRD0782KL and RT0805BRD0782KL) are suitable for general-purpose applications but lack automotive certification.

Q: Can I substitute a part with higher power rating? A: Yes. Parts with equal or higher power ratings are mechanically and electrically compatible. Higher power ratings provide additional thermal margin and do not affect circuit operation in applications designed for lower power ratings.

Q: Are all substitute parts available in the same package format? A: Yes. All listed substitutes use the 0805 (2012 Metric) package. Physical dimensions and PCB footprint compatibility are maintained across all alternatives.

Q: What does temperature coefficient mean, and does a lower value matter? A: Temperature coefficient (ppm/°C) indicates how much the resistance value changes per degree Celsius. Lower values (such as ±10ppm/°C vs ±25ppm/°C) indicate better stability across temperature variations. For precision analog circuits, lower temperature coefficients improve performance consistency.

Q: Is the RT0805DRD0782KL still in production? A: Yes. The part maintains Active product status with 685 units in current inventory. However, RT0805BRD0782KL from the same manufacturer offers improved specifications with significantly higher availability (16854 units).
