Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-274-B-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 270 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Automotive AEC-Q200 qualification
• RoHS3 compliance
• Moisture Sensitivity Level: 1

Allowable Variation Parameters:

• Tolerance: ±0.1% or tighter (±0.05%)
• Power rating: 0.125W or higher
• Temperature coefficient: ±10ppm/°C or ±25ppm/°C
• Operating temperature range: -55°C to 155°C or extended to 175°C
• Packaging format: Bulk or Tape & Reel (TR)
• Product status: Active or Obsolete

Substitute parts must maintain electrical performance within the specified resistance, tolerance, and power dissipation requirements while preserving mechanical compatibility and automotive qualification standards.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Specifications): RG2012N-274-B-T5 is the direct active equivalent to RG2012N-274-B-T1. Both parts share identical electrical specifications (270 kOhms ±0.1%, 0.125W, ±10ppm/°C) and mechanical compatibility. The primary difference is packaging format (Tape & Reel versus Bulk) and active product status. This part is recommended for direct replacement in production environments.

Tolerance-Enhanced Alternatives: RG2012N-274-W-T1 and RG2012N-274-W-T5 offer improved tolerance (±0.05% versus ±0.1%) while maintaining all other electrical and mechanical parameters. These parts are suitable for applications requiring tighter resistance accuracy. Both are active products supplied in Tape & Reel format.

Alternative Manufacturer Option: TNPW0805270KBYEA (Vishay Dale) provides equivalent 270 kOhms ±0.1% resistance with enhanced power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C to 175°C). This part maintains AEC-Q200 qualification and RoHS3 compliance. Selection of this alternative is appropriate when higher power dissipation capability or extended temperature performance is required.

Temperature Coefficient Variant: RG2012P-274-B-T5 differs only in temperature coefficient (±25ppm/°C versus ±10ppm/°C). This part is suitable for applications where the relaxed temperature coefficient specification is acceptable.

All substitute parts maintain automotive AEC-Q200 qualification, RoHS3 compliance, and Moisture Sensitivity Level 1 rating, ensuring compatibility with automotive and high-reliability design requirements.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-274-B-T5 be used as a direct replacement for RG2012N-274-B-T1?

A: Yes. RG2012N-274-B-T5 is electrically and mechanically identical to RG2012N-274-B-T1. The only difference is packaging format (Tape & Reel versus Bulk). Both parts have identical resistance (270 kOhms), tolerance (±0.1%), power rating (0.125W), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C to 155°C). RG2012N-274-B-T5 is an active product, making it the preferred choice for new production.

Q: What is the difference between RG2012N-274-B-T5 and RG2012P-274-B-T5?

A: The primary difference is temperature coefficient. RG2012N-274-B-T5 has ±10ppm/°C, while RG2012P-274-B-T5 has ±25ppm/°C. All other specifications are identical. Selection depends on the application's temperature stability requirements.

Q: Are the RG2012N-274-W variants (±0.05% tolerance) compatible with designs specified for ±0.1% tolerance?

A: Yes. The RG2012N-274-W variants (RG2012N-274-W-T1 and RG2012N-274-W-T5) have tighter tolerance (±0.05%) than the original specification (±0.1%). Tighter tolerance is a performance enhancement and does not create compatibility issues. These parts are suitable for applications requiring improved accuracy.

Q: Can TNPW0805270KBYEA replace RG2012N-274-B-T1?

A: Yes, with considerations. TNPW0805270KBYEA is electrically compatible (270 kOhms ±0.1%, ±10ppm/°C) and maintains AEC-Q200 qualification and RoHS3 compliance. Differences include higher power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C to 175°C). Physical dimensions are nearly identical (0.079" L x 0.049" W). This part is suitable for replacement and offers enhanced performance margins.

Q: What does the packaging designation "T1" versus "T5" mean?

A: "T1" indicates Bulk packaging, while "T5" indicates Tape & Reel (TR) packaging. Both formats contain the same component. Selection depends on assembly process requirements. Tape & Reel format is standard for automated pick-and-place assembly, while Bulk format is used for manual assembly or lower-volume applications.

Q: Are all substitute parts RoHS3 compliant and AEC-Q200 qualified?

A: Yes. All substitute parts listed maintain ROHS3 compliance and automotive AEC-Q200 qualification, ensuring compatibility with automotive and high-reliability design standards.

Q: What is Moisture Sensitivity Level 1?

A: Moisture Sensitivity Level 1 indicates unlimited shelf life without moisture control requirements. The component does not require special storage conditions or baking procedures prior to assembly, providing maximum handling flexibility.
