Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805CRE0740K2L is determined by the following mandatory parameters:

• Resistance Value: Must be 40.2 kOhms (exact match required)
• Package Type: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Composition: Thin film construction required
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Termination Count: Must be 2 terminations
• RoHS Compliance: Must be RoHS3 compliant

Tolerance, power rating, and temperature coefficient may vary within acceptable engineering parameters. Substitute parts with improved tolerance (±0.1% vs ±0.25%) or higher power ratings (0.25W vs 0.125W) are acceptable upgrades. Automotive AEC-Q200 certification and anti-sulfur features represent enhanced specifications suitable for demanding applications.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD0740K2L (YAGEO): Direct upgrade within the same manufacturer series. Maintains identical package and power rating while improving tolerance from ±0.25% to ±0.1% and reducing temperature coefficient from ±50ppm/°C to ±25ppm/°C. Suitable for applications requiring tighter tolerance specifications without automotive requirements.

5-2176093-8 (TE Connectivity): Provides ±0.1% tolerance and ±25ppm/°C temperature coefficient with increased power rating of 0.25W (1/4W). Appropriate for applications with higher power dissipation margins or where additional thermal headroom is beneficial. Maintains identical package dimensions and operating temperature range.

ERA-6AEB4022V (Panasonic): Offers ±0.1% tolerance with AEC-Q200 automotive qualification. Suitable for automotive and high-reliability applications requiring automotive-grade component certification. Maintains 0.125W power rating and identical package specifications.

RG2012P-4022-B-T5 (Susumu): Combines ±0.1% tolerance with AEC-Q200 automotive qualification and anti-sulfur feature. Designed for automotive environments with corrosive exposure risk. Maintains 0.125W power rating with lowest maximum seated height (0.020" vs 0.024-0.026") among substitute options.

All substitute parts maintain RoHS3 compliance, MSL 1 rating, and identical operating temperature range (-55°C to 155°C). Selection should be based on specific application requirements for tolerance, power dissipation, automotive qualification, and environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0740K2L replace RT0805CRE0740K2L directly?

A: Yes. Both parts share identical resistance value (40.2 kOhms), package (0805), power rating (0.125W), and operating temperature range (-55°C to 155°C). RT0805BRD0740K2L provides improved tolerance (±0.1% vs ±0.25%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct upgrade.

Q: What is the difference between 5-2176093-8 and other substitutes?

A: 5-2176093-8 is manufactured by TE Connectivity and features a higher power rating of 0.25W (1/4W) compared to 0.125W in other options. This provides additional thermal margin for applications with higher power dissipation. All other electrical and mechanical parameters remain compatible.

Q: Are ERA-6AEB4022V and RG2012P-4022-B-T5 suitable for automotive applications?

A: Both parts carry AEC-Q200 automotive qualification. ERA-6AEB4022V is standard automotive-grade. RG2012P-4022-B-T5 adds anti-sulfur feature for enhanced corrosion resistance in harsh automotive environments. Both maintain identical 0805 package and -55°C to 155°C operating range.

Q: Does package size differ among substitute parts?

A: All parts use 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Maximum seated height varies slightly: RT0805CRE0740K2L and ERA-6AEB4022V at 0.024" (0.60mm), 5-2176093-8 at 0.026" (0.65mm), and RG2012P-4022-B-T5 at 0.020" (0.50mm). These variations are within standard PCB assembly tolerances.

Q: Can I use a substitute with higher tolerance in a precision circuit?

A: Tolerance selection depends on circuit requirements. RT0805CRE0740K2L at ±0.25% is suitable for general-purpose applications. All substitute parts offer ±0.1% tolerance, which is appropriate for precision analog circuits, reference networks, and applications requiring tighter component matching.

Q: What does MSL 1 rating mean for these parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture baking requirements. All listed parts carry MSL 1 rating, meaning they can be stored and handled under standard conditions without special moisture control procedures.
