Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-1741-D-T5 is permissible when the following criteria are met:

Mandatory Matching Parameters:

• Resistance value: 1.74 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Number of Terminations: 2
• Automotive AEC-Q200 rating

Allowable Upgrade Parameters: Substitute parts may exceed the original specifications in the following areas without compromising compatibility:

• Tolerance: Tighter tolerance (lower percentage) is acceptable
• Power Rating: Higher power dissipation rating is acceptable
• Operating Temperature Range: Extended upper temperature limit is acceptable
• Temperature Coefficient: Equivalent or better stability is acceptable

The TNPW08051K74BYEA from Vishay Dale qualifies as a direct substitute based on identical resistance, package, composition, and AEC-Q200 rating, with improvements in tolerance (±0.1% vs ±0.5%), power rating (0.26W vs 0.125W), and maximum operating temperature (175°C vs 155°C).

Engineering Selection Recommendations

Primary Part Selection: The RG2012N-1741-D-T5 (Susumu) is the specified component and should be used when design requirements explicitly call for this part number and when inventory availability permits.

Substitute Part Selection: The TNPW08051K74BYEA (Vishay Dale) is a qualified substitute when:

• The original part is unavailable or subject to supply constraints
• Design specifications permit tolerance of ±0.1% or tighter
• Operating conditions do not exceed 175°C maximum temperature
• PCB layout accommodates a maximum seated height of 0.022" (0.55mm)
• Automotive AEC-Q200 qualification is required

Both parts maintain ROHS3 compliance, MSL 1 rating, and identical electrical performance at the nominal 1.74 kOhms resistance value. The substitute part provides enhanced performance margins through higher power rating and extended temperature range, making it suitable for applications with more demanding thermal or reliability requirements.

Frequently Asked Questions (FAQ)

Q: Can TNPW08051K74BYEA replace RG2012N-1741-D-T5 in all applications?

A: The TNPW08051K74BYEA is mechanically and electrically compatible with the RG2012N-1741-D-T5 in applications where the maximum seated height of 0.022" (0.55mm) does not conflict with PCB design constraints. The substitute part's tighter tolerance and higher power rating do not create incompatibility issues.

Q: What is the significance of the tolerance difference between ±0.5% and ±0.1%?

A: Both parts deliver the same nominal 1.74 kOhms resistance value. The ±0.1% tolerance on the substitute part represents a tighter manufacturing specification, resulting in resistors with values closer to the nominal specification. This provides improved circuit accuracy when required by design specifications.

Q: Are there thermal performance differences between these parts?

A: The TNPW08051K74BYEA has a higher power rating (0.26W vs 0.125W) and extended operating temperature range (-55°C ~ 175°C vs -55°C ~ 155°C). These characteristics allow the substitute part to operate in higher temperature environments and dissipate more power without exceeding rated limits.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the RG2012N-1741-D-T5 and TNPW08051K74BYEA carry AEC-Q200 automotive qualification and ROHS3 compliance, making them suitable for automotive applications.

Q: What is the physical size difference between these parts?

A: Both parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). The seated height differs slightly: RG2012N-1741-D-T5 is 0.020" (0.50mm) maximum, while TNPW08051K74BYEA is 0.022" (0.55mm) maximum. This 0.002" (0.05mm) difference is negligible for most PCB designs but should be verified for space-constrained applications.

Q: Is moisture sensitivity a concern for either part?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations during storage or handling.
