Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-2151-P-T1 is determined by the following critical parameters:

Primary Substitution Criteria (Must Match):

• Resistance value: 2.15 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant

Secondary Substitution Criteria (Allowable Variation):

• Tolerance: ±0.02% or tighter (lower tolerance values are acceptable)
• Power Rating: 0.125W or higher (higher power ratings are acceptable)
• Temperature Coefficient: ±10ppm/°C or better (lower values are acceptable)
• Automotive AEC-Q200 rating: Preferred for automotive applications but not mandatory for all use cases

Substitute parts are classified into two categories:

Upgrade Substitute: Direct replacement with improved or equivalent specifications and active product status.

Similar Substitute: Functionally compatible component with acceptable parameter variations within engineering tolerances.

Engineering Selection Recommendations

RG2012V-2151-P-T1 (Upgrade Substitute - Recommended Primary Choice)

The RG2012V-2151-P-T1 is the preferred substitute for the obsolete RG2012N-2151-P-T1. This component is manufactured by Susumu and maintains identical electrical specifications with the exception of an improved temperature coefficient (±5ppm/°C versus ±10ppm/°C). The upgrade substitute carries active product status, ensuring long-term availability and supply chain continuity. Both components share identical resistance value, tolerance, power rating, package configuration, and automotive AEC-Q200 qualification. Physical dimensions and seated height are identical, enabling direct board-level substitution without layout modifications. ROHS3 compliance and MSL 1 rating are maintained.

RN73C2A2K15BTDF (Similar Substitute - Secondary Choice)

The RN73C2A2K15BTDF manufactured by TE Connectivity Passive Product serves as a functionally compatible alternative when the primary upgrade substitute is unavailable. This component maintains the same 2.15 kOhms resistance value, 0805 package, thin film composition, and operating temperature range. The tolerance specification is relaxed to ±0.1% (compared to ±0.02%), and the power rating is reduced to 0.1W (1/10W) versus the original 0.125W. The seated height is increased to 0.026" (0.65mm) from 0.020" (0.50mm), requiring verification of board clearance in height-constrained applications. This component lacks automotive AEC-Q200 certification and anti-sulfur coating. Selection of this substitute is appropriate for non-automotive applications or where tolerance relaxation and reduced power dissipation are acceptable.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-2151-P-T1 be used as a direct replacement for RG2012N-2151-P-T1?

A: Yes. The RG2012V-2151-P-T1 is a direct substitute with identical electrical and mechanical specifications. The improved temperature coefficient (±5ppm/°C) provides enhanced performance. Both components are manufactured by Susumu, share the same 0805 package, and maintain AEC-Q200 automotive qualification.

Q: What are the key differences between RG2012V-2151-P-T1 and RN73C2A2K15BTDF?

A: The primary differences are tolerance (±0.02% versus ±0.1%), power rating (0.125W versus 0.1W), seated height (0.020" versus 0.026"), and automotive certification (AEC-Q200 present versus absent). The RN73C2A2K15BTDF is suitable for applications where these parameter variations are acceptable.

Q: Is the RN73C2A2K15BTDF suitable for automotive applications?

A: The RN73C2A2K15BTDF lacks automotive AEC-Q200 certification and anti-sulfur coating. For automotive applications requiring these qualifications, the RG2012V-2151-P-T1 is the appropriate choice.

Q: Will the increased seated height of RN73C2A2K15BTDF (0.026" versus 0.020") cause assembly issues?

A: The height difference of 0.006" (0.15mm) must be evaluated against specific board design constraints. Applications with tight vertical clearance requirements should use the RG2012V-2151-P-T1 to maintain original specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both RG2012V-2151-P-T1 and RN73C2A2K15BTDF are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original component.

Q: What is the impact of the tolerance difference between RG2012N-2151-P-T1 (±0.02%) and RN73C2A2K15BTDF (±0.1%)?

A: The RN73C2A2K15BTDF tolerance is wider by a factor of five. For precision analog circuits, signal conditioning, or reference applications requiring tight tolerance control, the RG2012V-2151-P-T1 with ±0.02% tolerance is the appropriate selection.

Q: Can RG2012V-2151-P-T1 be used in applications originally designed for RG2012N-2151-P-T1?

A: Yes. The RG2012V-2151-P-T1 meets or exceeds all electrical and mechanical requirements of the original component. The improved temperature coefficient provides superior performance in temperature-sensitive applications.
