Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE07191RL is determined by the following critical parameters:

• Resistance Value: Must be 191 Ohms (exact match required)
• Package Type: Must be 0402 (1005 Metric) for PCB footprint compatibility
• Power Rating: Must be 0.063W (1/16W) minimum
• Composition: Thin film construction required for performance consistency
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Compliance: ROHS3 compliance required for regulatory alignment

All substitute parts listed meet these core requirements. Variations in tolerance, temperature coefficient, and manufacturer-specific features represent performance enhancements or application-specific optimizations rather than functional incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

CPF0402B191RE1 (TE Connectivity Passive Product): Offers ±0.1% tolerance with ±25ppm/°C temperature coefficient. Maintains full -55°C to 155°C operating range with ROHS3 compliance. Suitable for general industrial and commercial applications requiring improved tolerance performance over the original specification.

ERA-2AEB1910X (Panasonic Electronic Components): Provides ±0.1% tolerance with ±25ppm/°C temperature coefficient and AEC-Q200 automotive qualification. Maintains full -55°C to 155°C operating range with ROHS3 compliance. Specified for automotive and mission-critical applications where automotive-grade component certification is required.

RN73C1E191RBTDF (TE Connectivity Passive Product): Delivers ±0.1% tolerance with superior ±10ppm/°C temperature coefficient. Maintains full -55°C to 155°C operating range with ROHS3 compliance. Specified for precision applications where minimal temperature-dependent resistance drift is critical.

RR0510P-1910-D (Susumu): Provides ±0.5% tolerance with ±25ppm/°C temperature coefficient and ROHS3 compliance. Operating temperature range limited to -55°C to 125°C. Suitable for cost-optimized applications where the reduced upper temperature limit does not conflict with system requirements.

Frequently Asked Questions (FAQ)

Q: Can I directly substitute RT0402FRE07191RL with any of these parts without PCB redesign?

A: Yes. All substitute parts use identical 0402 (1005 Metric) package dimensions and footprints. Direct PCB-level substitution is mechanically and electrically compatible without layout modifications.

Q: What is the primary difference between the original part and the substitute options?

A: The original RT0402FRE07191RL specifies ±1% tolerance with ±50ppm/°C temperature coefficient. All substitute parts offer improved tolerance (±0.1% to ±0.5%) and reduced temperature coefficients (±10ppm/°C to ±25ppm/°C), resulting in superior stability and accuracy across operating conditions.

Q: Which substitute part should I select for automotive applications?

A: ERA-2AEB1910X carries AEC-Q200 automotive qualification and is specified for automotive-grade component requirements. Other substitutes lack automotive certification.

Q: Is there a substitute option with the lowest temperature coefficient?

A: RN73C1E191RBTDF provides the lowest temperature coefficient at ±10ppm/°C, making it optimal for precision analog circuits where temperature-dependent resistance variation must be minimized.

Q: Does RR0510P-1910-D have any operational limitations compared to other substitutes?

A: RR0510P-1910-D operates to a maximum of 125°C, compared to 155°C for all other options. Applications requiring full -55°C to 155°C range should use alternative substitutes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's regulatory status.

Q: What is the impact of tolerance differences on circuit performance?

A: Tighter tolerance specifications (±0.1% vs ±1%) reduce resistance value variation across production batches. In precision applications such as gain-setting resistors or reference networks, this improves circuit accuracy and reduces calibration requirements.
