Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0784K5L is determined by the following criteria:

Primary Substitution Parameters:

• Resistance value: 84.5 kOhms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or broader range acceptable)
• Moisture sensitivity: MSL 1 (Unlimited) (equal or lower MSL acceptable)

Secondary Substitution Parameters:

• Tolerance: ±1% or better (tighter tolerance acceptable as upgrade)
• Power rating: 0.125W minimum (higher power rating acceptable as upgrade)
• Temperature coefficient: ±50ppm/°C or better (lower coefficient acceptable as upgrade)
• RoHS compliance: ROHS3 or equivalent (maintained or improved)

The substitute parts identified below meet the primary parameters and represent either direct equivalents or performance upgrades within the allowed electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD0784K5L (YAGEO Upgrade): This part provides improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical power rating, package, and RoHS3 compliance. Selection is appropriate for applications requiring tighter resistance accuracy without changing thermal or compliance characteristics.

8-2176093-8 (TE Connectivity Direct Substitute): This part matches the 84.5 kOhms resistance and 0805 package with improved tolerance (±0.1%) and higher power rating (0.25W versus 0.125W). However, this part is RoHS non-compliant, making it unsuitable for applications requiring ROHS3 compliance. Selection is limited to legacy systems or applications where RoHS compliance is not mandated.

ERA-6AEB8452V (Panasonic Upgrade): This part delivers improved tolerance (±0.1%), lower temperature coefficient (±25ppm/°C), and AEC-Q200 automotive qualification while maintaining ROHS3 compliance and identical power rating and package. Selection is appropriate for automotive applications or systems requiring automotive-grade component reliability.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0784K5L replace RT0805FRE0784K5L in any application?

A: Yes. RT0805BRD0784K5L is a direct upgrade offering tighter tolerance and lower temperature coefficient. All electrical, thermal, and compliance parameters remain compatible or improved. No circuit redesign is required.

Q: Is 8-2176093-8 suitable for RoHS-compliant applications?

A: No. The 8-2176093-8 is RoHS non-compliant. It cannot be used in applications requiring ROHS3 compliance. Use RT0805BRD0784K5L or ERA-6AEB8452V instead.

Q: What is the difference between the main part and ERA-6AEB8452V?

A: ERA-6AEB8452V offers improved tolerance (±0.1% versus ±1%), lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), and AEC-Q200 automotive qualification. All other parameters including power rating, package, and RoHS compliance remain equivalent.

Q: Can I use a higher power-rated resistor (8-2176093-8 at 0.25W) in place of the 0.125W main part?

A: Yes. Higher power rating is acceptable and provides additional thermal margin. The 0.25W rating does not negatively impact circuit performance. However, verify RoHS compliance requirements before selection.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging and use the 0805 (2012 Metric) package. No PCB layout or assembly process changes are required.

Q: Which substitute part should I select for automotive applications?

A: ERA-6AEB8452V is the appropriate choice for automotive applications due to AEC-Q200 qualification. It maintains ROHS3 compliance and provides performance upgrades over the main part.
