Substitute Part Grouping Explanation

Substitute parts for the AT0805DRD07191RL are qualified based on the following criteria:

• Identical resistance value: 191 Ohms
• Identical package: 0805 (2012 Metric)
• Identical composition: Thin Film
• Identical temperature coefficient: ±25ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical MSL rating: MSL 1 (Unlimited)
• Identical RoHS compliance: ROHS3 Compliant
• Tolerance equal to or tighter than ±0.5%
• Power rating equal to or greater than 0.125W

Two substitute parts meet these criteria: the TE Connectivity 5-2176091-1 and the Panasonic ERA-6AEB1910V. Both parts maintain the same physical footprint, electrical characteristics, and environmental ratings as the original part.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and MSL 1 ratings, ensuring compatibility in standard PCB assembly processes.

The AT0805DRD07191RL and ERA-6AEB1910V both carry AEC-Q200 automotive qualification. Selection between these two depends on application requirements: the original part offers ±0.5% tolerance with anti-sulfur coating, while the ERA-6AEB1910V provides tighter ±0.1% tolerance with identical power rating and automotive certification.

The TE Connectivity 5-2176091-1 offers tighter ±0.1% tolerance and higher 0.25W power rating but lacks AEC-Q200 automotive qualification. This part is suitable for non-automotive applications where enhanced power dissipation capability is beneficial.

Height variation between the TE Connectivity part (0.026" maximum) and the other two parts (0.024" maximum) is within typical PCB assembly tolerances but should be verified for applications with strict height constraints.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-2176091-1 replace the AT0805DRD07191RL in automotive applications?

A: The TE Connectivity part lacks AEC-Q200 automotive qualification. For automotive applications, use the ERA-6AEB1910V, which maintains AEC-Q200 certification while providing tighter tolerance.

Q: What is the difference between ±0.5% and ±0.1% tolerance?

A: Tolerance specifies the maximum deviation from the nominal resistance value. The ±0.1% tolerance parts (5-2176091-1 and ERA-6AEB1910V) provide more precise resistance values compared to the ±0.5% tolerance of the original part. Selection depends on circuit accuracy requirements.

Q: Are all three parts physically interchangeable?

A: All three parts use the 0805 (2012 Metric) package with identical length and width (0.079" x 0.049"). The TE Connectivity part has a maximum seated height of 0.026" compared to 0.024" for the other two parts. Verify height clearance for your specific PCB layout.

Q: Can I use a higher power-rated resistor as a substitute?

A: Yes. The TE Connectivity 5-2176091-1 with 0.25W rating can replace the 0.125W original part. Higher power rating provides additional thermal margin and does not negatively affect circuit performance in this application category.

Q: What does MSL 1 (Unlimited) mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All three parts share this rating.
