Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 15.4 kOhms (exact match required)
• Package: 0805 (2012 Metric) (physical and electrical compatibility)
• Composition: Thin Film (electrical performance characteristics)
• Operating temperature range: -55°C to 155°C (minimum requirement)

Tolerance Upgrade Path: Parts with ±0.1% tolerance are direct upgrades to the ±1% specification and are electrically interchangeable. Tighter tolerance does not restrict application scope.

Power Rating Consideration: The RT0805FRE0715K4L operates at 0.125W. Substitute 2-2176093-1 provides 0.25W rating in the same package, offering higher power dissipation capability while maintaining all other electrical parameters.

Automotive Qualification: ERA-6AEB1542V and RG2012P-1542-B-T5 include AEC-Q200 automotive qualification. This certification is an enhancement and does not restrict use in non-automotive applications.

Temperature Coefficient: The main part specifies ±50ppm/°C. Substitute parts with ±25ppm/°C provide improved temperature stability and are functionally superior.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD0715K4L (YAGEO): Direct upgrade within the same manufacturer series. Improves tolerance to ±0.1% and reduces temperature coefficient to ±25ppm/°C while maintaining identical power rating and package. Recommended for applications requiring tighter tolerance control without changing supplier.

2-2176093-1 (TE Connectivity): Suitable when higher power dissipation capacity is required. Provides 0.25W rating with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Maintains 0805 package compatibility. Recommended for thermal margin applications.

ERA-6AEB1542V (Panasonic): Automotive-qualified option with AEC-Q200 certification. Matches the main part's 0.125W power rating with improved ±0.1% tolerance and ±25ppm/°C temperature coefficient. Recommended for automotive applications or when AEC-Q200 compliance is specified.

RG2012P-1542-B-T5 (Susumu): Automotive-qualified with anti-sulfur feature and AEC-Q200 certification. Provides ±0.1% tolerance and ±25ppm/°C temperature coefficient in 0.125W rating. Recommended for harsh automotive environments or when sulfur resistance is required.

All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) rating.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0715K4L replace RT0805FRE0715K4L directly? A: Yes. Both parts share identical resistance, power rating, package, and operating temperature range. The substitute offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct upgrade.

Q: What is the difference between 0.125W and 0.25W power ratings? A: Power rating indicates maximum continuous power dissipation. The 0.25W rating of 2-2176093-1 allows higher current handling in the same physical package. Selection depends on circuit power requirements. A 0.25W part can be used in applications designed for 0.125W without derating concerns.

Q: Are automotive-qualified parts usable in non-automotive applications? A: Yes. AEC-Q200 certification indicates enhanced reliability testing and qualification. Parts meeting automotive standards are suitable for any application, including non-automotive designs.

Q: What does anti-sulfur feature mean? A: Anti-sulfur coating protects the resistor from sulfur-containing environmental contaminants, particularly relevant in industrial and automotive environments with high sulfur exposure. This feature does not affect electrical performance in standard environments.

Q: Can I mix different substitute parts in the same design? A: Yes, provided all parts meet the circuit's electrical requirements. All listed substitutes maintain the same 15.4 kOhms resistance, 0805 package, and operating temperature range. Verify power dissipation requirements and tolerance specifications for your specific application.

Q: What does ±1% vs ±0.1% tolerance mean for circuit performance? A: Tolerance specifies the maximum deviation from the nominal 15.4 kOhms value. ±1% allows ±154 Ohms deviation; ±0.1% allows ±15.4 Ohms deviation. Tighter tolerance is required in precision circuits, filters, and reference networks where resistance accuracy directly affects performance.

Q: Are all parts ROHS3 compliant? A: Yes. All listed parts meet ROHS3 compliance requirements and are suitable for applications with RoHS restrictions.
