Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Resistance Value: All substitute parts must be 2.37 kOhms
• Tolerance: All substitute parts must maintain ±0.1% tolerance
• Package: All substitute parts must use 0805 (2012 Metric) package
• Composition: All substitute parts must be thin film construction
• Temperature Coefficient: All substitute parts must be ±25ppm/°C
• Compliance: All substitute parts must be ROHS3 compliant and AEC-Q200 rated

The substitute parts are grouped into two categories based on power rating compatibility:

Category A (Direct Substitutes - Lower Power Rating): ERA-6AEB2371V, RG2012P-2371-B-T5, and RT0805BRD072K37L operate at 0.125W (1/8W), which is lower than the main part's 0.26W rating. These are suitable for applications where the circuit design does not require the full 0.26W dissipation capability.

Category B (Manufacturer Recommended - Equivalent Power Rating): 4-2176092-9 operates at 0.25W (1/4W), which closely matches the main part's 0.26W rating and represents the manufacturer-recommended alternative.

Parameter Comparison

Engineering Selection Recommendations

For Automotive AEC-Q200 Applications: ERA-6AEB2371V (Panasonic) and RG2012P-2371-B-T5 (Susumu) are direct substitutes with AEC-Q200 qualification. Both maintain the required tolerance, temperature coefficient, and operating temperature range. RG2012P-2371-B-T5 includes anti-sulfur coating matching the original part's environmental protection. ERA-6AEB2371V offers higher inventory availability (14,253 units) and alternative packaging options.

For Power Dissipation Matching: 4-2176092-9 (TE Connectivity) provides the closest power rating at 0.25W, approximating the original 0.26W specification. This part is suitable for applications where power dissipation margins are critical. Note that this part does not carry AEC-Q200 rating.

For General Industrial Applications: RT0805BRD072K37L (YAGEO) meets all electrical parameters with 11,656 units in stock. This part does not carry AEC-Q200 rating and lacks anti-sulfur coating, making it suitable for non-automotive environments.

For Thermal Margin Considerations: The main part TNPW08052K37BEEA operates to 175°C, while all substitute parts are rated to 155°C maximum. Applications requiring operation above 155°C must retain the original part.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB2371V replace TNPW08052K37BEEA in automotive applications?

A: ERA-6AEB2371V is electrically and mechanically compatible with AEC-Q200 qualification. The lower power rating (0.125W vs. 0.26W) is acceptable if circuit analysis confirms power dissipation does not exceed 0.125W. The operating temperature range is reduced to 155°C maximum.

Q: What is the difference between the substitute parts?

A: All substitute parts share identical resistance (2.37 kOhms), tolerance (±0.1%), and package (0805). Differences exist in power rating, operating temperature maximum, AEC-Q200 qualification, anti-sulfur coating, and packaging format. RG2012P-2371-B-T5 and ERA-6AEB2371V are AEC-Q200 rated; 4-2176092-9 and RT0805BRD072K37L are not.

Q: Is the 0805 package dimension identical across all parts?

A: All parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Seated height varies between 0.020" and 0.026", which may affect PCB layout clearance in space-constrained designs.

Q: Which substitute part has the best inventory availability?

A: Panasonic ERA-6AEB2371V has the highest inventory with 14,253 units in stock, followed by YAGEO RT0805BRD072K37L with 11,656 units.

Q: Can I use a lower power-rated substitute in a high-power dissipation circuit?

A: No. Using a 0.125W part in a circuit designed for 0.26W dissipation will cause component failure. Circuit analysis must confirm actual power dissipation before selecting a lower-rated substitute.

Q: What is the significance of anti-sulfur coating?

A: Anti-sulfur coating protects the resistor in environments with hydrogen sulfide exposure. TNPW08052K37BEEA and RG2012P-2371-B-T5 include this feature. Other substitutes lack this protection and are unsuitable for sulfur-rich environments.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original part's environmental compliance.
