Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0603CRE07191RL are qualified based on the following criteria:

• Identical resistance value: 191 Ohms
• Identical package: 0603 (1608 Metric)
• Identical power rating: 0.1W
• Identical operating temperature range: -55°C ~ 155°C
• Identical composition: Thin Film
• Identical termination count: 2
• Identical RoHS3 compliance and MSL rating

Substitutes may offer improved tolerance (±0.1% versus ±0.25%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C). Additional qualifications such as automotive AEC-Q200 certification represent enhanced reliability for specific applications but do not affect basic electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

RT0603BRD07191RL represents a direct upgrade path within the YAGEO RT series, offering improved tolerance specification (±0.1% versus ±0.25%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package, power rating, and operating temperature range. Both components share ROHS3 compliance and unlimited moisture sensitivity rating.

ERA-3AEB1910V from Panasonic Electronic Components provides equivalent electrical performance with identical tolerance and temperature coefficient specifications. This part includes AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability. All three parts maintain full compatibility in 0603 package footprints and identical electrical operating parameters.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRD07191RL be used as a direct replacement for RT0603CRE07191RL?

A: Yes. Both parts share identical resistance (191 Ohms), power rating (0.1W), package (0603), operating temperature range (-55°C ~ 155°C), and RoHS3 compliance. RT0603BRD07191RL offers improved tolerance (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C).

Q: What is the difference between RT0603CRE07191RL and ERA-3AEB1910V?

A: Both parts are electrically equivalent with identical resistance, power rating, package, and operating temperature. ERA-3AEB1910V includes AEC-Q200 automotive qualification. RT0603CRE07191RL has ±0.25% tolerance and ±50ppm/°C temperature coefficient, while ERA-3AEB1910V has ±0.1% tolerance and ±25ppm/°C temperature coefficient.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 0603 (1608 Metric) package with identical dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm) and maximum seated height (0.022" / 0.55mm). They are footprint-compatible for direct PCB substitution.

Q: Does the improved tolerance of substitute parts affect circuit performance?

A: Tolerance improvement from ±0.25% to ±0.1% reduces resistor value variation. This affects circuits where precise resistance values are critical. The reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C) provides better stability across the -55°C ~ 155°C operating range.

Q: Is AEC-Q200 certification required for non-automotive applications?

A: No. AEC-Q200 certification is specific to automotive applications. For non-automotive use, RT0603CRE07191RL and RT0603BRD07191RL are fully qualified. ERA-3AEB1910V remains compatible but the automotive qualification provides no additional benefit outside automotive environments.
