Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE07191RL is determined by the following mandatory parameters:

• Resistance value: 191 Ohms (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 wider range acceptable)
• RoHS compliance: ROHS3 Compliant (equal or higher compliance acceptable)
• Moisture sensitivity: MSL Level 1 or better (equal or lower MSL acceptable)

Tolerance, temperature coefficient, and power rating may vary within acceptable engineering limits for the application. Substitute parts must maintain electrical and mechanical compatibility with the original design footprint and thermal requirements.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the RT0805FRE07191RL within the specified 0805 package footprint.

The 5-2176091-1 (TE Connectivity) offers improved tolerance (±0.1% versus ±1%) and higher power rating (0.25W versus 0.125W), with lower temperature coefficient (±25ppm/°C). The increased height (0.026" maximum seated height) must be verified against PCB clearance constraints. This part is suitable for applications requiring enhanced precision and thermal headroom.

The ERA-6AEB1910V (Panasonic) provides improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C) while maintaining the original power rating (0.125W) and height profile (0.024" maximum seated height). This part carries AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications. All three parts are ROHS3 compliant with MSL Level 1 rating and identical operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can the 5-2176091-1 be used as a direct replacement for the RT0805FRE07191RL?

A: Yes, the 5-2176091-1 is electrically and mechanically compatible. The 0.002" (0.05mm) increase in maximum seated height must be verified against PCB assembly clearances. The higher power rating (0.25W) and improved tolerance (±0.1%) provide additional design margin.

Q: What is the advantage of the ERA-6AEB1910V over the original RT0805FRE07191RL?

A: The ERA-6AEB1910V offers improved tolerance (±0.1% versus ±1%), lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), and AEC-Q200 automotive qualification. It maintains the same power rating and height profile as the original part.

Q: Are all three parts suitable for high-temperature applications?

A: Yes. All three parts share the same operating temperature range of -55°C to 155°C and are rated for continuous operation within this range.

Q: Do tolerance differences affect circuit performance?

A: Tolerance differences may impact circuits with tight resistance specifications. The RT0805FRE07191RL carries ±1% tolerance, while both substitute parts offer ±0.1% tolerance, providing tighter resistance control for precision applications.

Q: Are there any PCB assembly considerations when substituting these parts?

A: The 5-2176091-1 has a maximum seated height of 0.026" compared to 0.024" for the original and ERA-6AEB1910V. Verify clearance above the component during PCB design and assembly planning.

Q: Do all parts meet environmental compliance requirements?

A: Yes. All three parts are ROHS3 compliant, carry MSL Level 1 (Unlimited) moisture sensitivity rating, and are classified as EAR99 for export control purposes.
