Engineering Selection Recommendations

5-2176091-1 (TE Connectivity) provides direct substitution with improved specifications. This part maintains the same 0805 package and operating temperature range while offering tighter tolerance (±0.1% versus ±0.25%) and higher power rating (0.25W versus 0.125W). The temperature coefficient is improved to ±25ppm/°C. This part is suitable for applications where enhanced precision and thermal stability are beneficial within the same footprint. ROHS3 compliance and MSL Level 1 rating are maintained.

ERA-6AEB1910V (Panasonic) serves as an upgrade option with automotive-grade qualification (AEC-Q200). This part matches the original power rating (0.125W) and seated height (0.024"), providing a direct mechanical fit. Tolerance and temperature coefficient are improved to ±0.1% and ±25ppm/°C respectively. The AEC-Q200 certification indicates suitability for automotive applications requiring enhanced reliability standards. ROHS3 compliance and MSL Level 1 rating are maintained.

All three parts are currently active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 5-2176091-1 be used as a direct replacement for RT0805CRE07191RL?

A: Yes. Both parts share identical resistance value (191 Ohms), package type (0805), composition (thin film), and operating temperature range (-55°C to 155°C). The substitute offers improved tolerance (±0.1% versus ±0.25%), lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), and higher power rating (0.25W versus 0.125W). The seated height difference (0.026" versus 0.024") remains within 0805 package specifications.

Q: What is the difference between the two substitute parts?

A: 5-2176091-1 provides higher power dissipation capability (0.25W versus 0.125W) in the same package. ERA-6AEB1910V maintains the original power rating (0.125W) but includes AEC-Q200 automotive qualification. Both substitutes offer identical tolerance (±0.1%) and temperature coefficient (±25ppm/°C) improvements over the main part.

Q: Are all three parts ROHS3 compliant?

A: Yes. RT0805CRE07191RL, 5-2176091-1, and ERA-6AEB1910V are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Can ERA-6AEB1910V be used in non-automotive applications?

A: Yes. AEC-Q200 certification indicates automotive-grade reliability but does not restrict use in other applications. The part meets all electrical and mechanical specifications for general industrial and commercial use.

Q: What is the significance of the temperature coefficient difference?

A: Temperature coefficient (±50ppm/°C for the main part versus ±25ppm/°C for substitutes) indicates resistance value stability across temperature variations. Lower values represent better stability. Both substitute parts provide superior temperature stability, which is beneficial in precision measurement circuits and temperature-sensitive applications.

Q: Are the physical dimensions compatible with the original PCB layout?

A: Yes. All three parts use the 0805 (2012 Metric) package with identical length and width (0.079" L x 0.049" W). Seated height variations (0.024" to 0.026") are within standard 0805 package tolerances and do not affect PCB assembly compatibility.
