Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-331-B-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 330 Ohms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W minimum
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C minimum
• Automotive AEC-Q200 qualification (where applicable)
• RoHS3 compliance

Allowable Variations:

• Tolerance: Can be equal or tighter (±0.1%, ±0.05%, ±0.02%)
• Temperature coefficient: Can be equal or lower (±10ppm/°C, ±5ppm/°C)
• Power rating: Can exceed 0.125W (0.26W acceptable)
• Packaging format: Bulk or Tape & Reel (TR)
• Manufacturer: Susumu, YAGEO, Vishay Dale (qualified suppliers)

Substitute parts are grouped into direct equivalents (matching tolerance and temperature coefficient) and upgrades (improved tolerance or temperature stability).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Identical Specifications): RG2012N-331-B-T5 is the direct active equivalent to RG2012N-331-B-T1. Both parts share identical electrical specifications (330Ω ±0.1%, ±10ppm/°C, 0.125W) and automotive AEC-Q200 qualification. The primary difference is packaging format (Tape & Reel vs. Bulk) and active product status. This part is recommended for direct replacement in production environments.

Susumu RG Series Upgrades (Improved Tolerance): RG2012N-331-W-T1 and RG2012N-331-W-T5 offer tighter tolerance (±0.05%) while maintaining identical temperature coefficient (±10ppm/°C) and AEC-Q200 qualification. These upgrades are suitable for applications requiring enhanced precision without thermal performance changes.

Susumu RG Series Upgrades (Improved Temperature Stability): RG2012V-331-B-T5, RG2012V-331-W-T1, RG2012V-331-W-T5, and RG2012V-331-P-T1 feature reduced temperature coefficient (±5ppm/°C) compared to the original part (±10ppm/°C). RG2012V-331-P-T1 additionally provides the tightest tolerance (±0.02%). All maintain AEC-Q200 qualification and are suitable for temperature-sensitive applications.

Alternative Manufacturer Options: RT0805WRB07330RL (YAGEO) provides ±0.05% tolerance and ±10ppm/°C temperature coefficient in active status. This part lacks AEC-Q200 qualification and is suitable only for non-automotive applications.

TNPW0805330RBYEA (Vishay Dale) matches the original tolerance (±0.1%) and temperature coefficient (±10ppm/°C) with AEC-Q200 qualification. This part features higher power rating (0.26W vs. 0.125W) and extended operating temperature range (-55°C ~ 175°C), making it suitable for higher thermal stress environments.

Product Status Consideration: All substitute parts listed are in active production status, ensuring long-term availability and supply chain stability compared to the obsolete RG2012N-331-B-T1.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-331-B-T5 be used as a direct replacement for RG2012N-331-B-T1?

A: Yes. RG2012N-331-B-T5 is electrically and mechanically identical to RG2012N-331-B-T1. Both parts specify 330Ω ±0.1%, 0.125W power rating, ±10ppm/°C temperature coefficient, and AEC-Q200 qualification. The difference is packaging format (Tape & Reel vs. Bulk) and active product status. No circuit redesign is required.

Q: What is the difference between RG2012N and RG2012V series parts?

A: The RG2012V series features improved temperature coefficient (±5ppm/°C) compared to RG2012N series (±10ppm/°C). Both series maintain identical resistance, tolerance options, power rating, and AEC-Q200 qualification. RG2012V is recommended for applications with strict temperature stability requirements.

Q: Can I use TNPW0805330RBYEA as a substitute?

A: TNPW0805330RBYEA is electrically compatible (330Ω ±0.1%, ±10ppm/°C, AEC-Q200). However, it features higher power rating (0.26W vs. 0.125W) and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C). Physical dimensions differ slightly (height 0.55mm vs. 0.50mm). Verify PCB layout clearance before substitution.

Q: Is RT0805WRB07330RL suitable for automotive applications?

A: RT0805WRB07330RL lacks AEC-Q200 qualification and is not suitable for automotive applications. This part is restricted to consumer and industrial applications only.

Q: What tolerance should I select for my application?

A: Tolerance selection depends on circuit requirements. The original part specifies ±0.1%. Tighter tolerances (±0.05%, ±0.02%) are available in RG2012N-331-W and RG2012V-331-P variants for precision-critical circuits. Standard ±0.1% tolerance is adequate for general-purpose applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, matching the environmental compliance of the original RG2012N-331-B-T1.

Q: What is the difference between T1 and T5 packaging designations?

A: T1 and T5 designations indicate different tape reel specifications for automated assembly. Both are Tape & Reel (TR) packaging formats. Selection depends on assembly equipment compatibility. Electrical specifications remain identical between T1 and T5 variants of the same part number.

Q: Can I upgrade to a tighter tolerance part without circuit changes?

A: Yes. Upgrading from ±0.1% to ±0.05% or ±0.02% tolerance does not require circuit modifications. Tighter tolerance parts are direct substitutes that improve circuit accuracy without affecting functionality or compatibility.
