Engineering Selection Recommendations

RT0805BRD0786R6L (YAGEO): Direct upgrade within the same manufacturer series. Improves tolerance to ±0.1% and reduces temperature coefficient to ±25ppm/°C while maintaining identical power rating and package dimensions. Maintains ROHS3 compliance and unlimited MSL rating. Recommended for applications requiring improved tolerance performance without changing supplier.

1-2176091-8 (TE Connectivity): Provides ±0.1% tolerance and ±25ppm/°C temperature coefficient with increased power rating of 0.25W (1/4W). Height increases to 0.026" (0.65mm) maximum. ROHS3 compliant with unlimited MSL. Suitable for applications requiring higher power dissipation capability or when TE Connectivity supply chain is preferred.

ERA-6AEB86R6V (Panasonic): Offers ±0.1% tolerance and ±25ppm/°C temperature coefficient with AEC-Q200 automotive qualification. Maintains 0.125W power rating and 0.024" (0.60mm) maximum height. ROHS3 compliant with unlimited MSL. Recommended for automotive applications or when automotive-grade reliability is required.

All three substitutes are active production parts with adequate inventory availability and maintain full compatibility with the original part's operating temperature range and package footprint.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0786R6L replace RT0805FRE0786R6L in any application?

A: Yes. RT0805BRD0786R6L is a direct upgrade offering improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). All other parameters including resistance, power rating, package, and operating temperature are identical. No circuit modifications required.

Q: What is the primary difference between 1-2176091-8 and the other substitutes?

A: 1-2176091-8 has a higher power rating of 0.25W (1/4W) compared to 0.125W (1/8W) for the other parts. Maximum seated height is also 0.026" (0.65mm) versus 0.024" (0.60mm). This higher power rating allows greater current handling capability. Verify PCB layout clearance before substitution.

Q: Is ERA-6AEB86R6V suitable for non-automotive applications?

A: Yes. ERA-6AEB86R6V meets all electrical and mechanical requirements for the original part. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits. It provides equivalent or superior performance to the original part.

Q: Do all substitute parts have the same package footprint?

A: All parts use 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Maximum seated height is 0.024" (0.60mm) for RT0805BRD0786R6L and ERA-6AEB86R6V, and 0.026" (0.65mm) for 1-2176091-8. Verify PCB design clearance if height is a constraint.

Q: Can tolerance be relaxed when substituting?

A: No. Substitute parts must have tolerance equal to or tighter than the original ±1%. All listed substitutes offer ±0.1% tolerance, which is acceptable. Selecting a part with looser tolerance is not permitted.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All three substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original part's environmental compliance status.
