Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-6812-B-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 68.1 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 ~ 155°C or extended to -55°C ~ 175°C
• Packaging format: Bulk or Tape & Reel (TR)

Substitute parts are grouped into three categories: direct equivalents (identical specifications with different packaging), upgrades (enhanced tolerance or power rating), and similar alternatives (different manufacturers with equivalent performance).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for Obsolete Part Replacement):

RG2012N-6812-B-T5 is the direct equivalent to RG2012N-6812-B-T1. Both parts are manufactured by Susumu with identical electrical specifications (68.1 kΩ ±0.1%, 0.125W, ±10ppm/°C). The only difference is packaging format: the original uses bulk packaging while the substitute uses Tape & Reel format. RG2012N-6812-B-T5 is currently active in production, ensuring long-term availability and supply chain continuity.

Enhanced Tolerance Alternatives (Upgrade Options):

RG2012N-6812-W-T1 and RG2012N-6812-W-T5 offer tighter tolerance specifications (±0.05% versus ±0.1%) while maintaining all other electrical and mechanical parameters. Both are manufactured by Susumu and carry active product status. These parts are suitable for applications requiring higher precision without modification to circuit design.

Cross-Manufacturer Alternatives:

TNPW080568K1BYEA (Vishay Dale) provides equivalent resistance and tolerance with enhanced power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C). This part is suitable for applications with higher thermal stress or power dissipation requirements.

ERA-6AEB6812V (Panasonic Electronic Components) matches the original part's resistance, tolerance, and power rating. The temperature coefficient specification differs (±25ppm/°C versus ±10ppm/°C), which may impact precision applications requiring tighter thermal stability. This part is suitable for general-purpose applications where the broader temperature coefficient is acceptable.

All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with automotive and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-6812-B-T5 be used as a direct replacement for RG2012N-6812-B-T1?

A: Yes. RG2012N-6812-B-T5 is electrically and mechanically identical to RG2012N-6812-B-T1. The only difference is packaging format (Tape & Reel versus bulk). Both parts have identical resistance (68.1 kΩ), tolerance (±0.1%), power rating (0.125W), and temperature specifications. RG2012N-6812-B-T5 is currently in active production.

Q: What is the difference between the RG2012N-6812-B and RG2012N-6812-W series?

A: The primary difference is tolerance specification. The B-series (RG2012N-6812-B-T1 and RG2012N-6812-B-T5) offers ±0.1% tolerance, while the W-series (RG2012N-6812-W-T1 and RG2012N-6812-W-T5) offers tighter ±0.05% tolerance. All other specifications remain identical. The W-series is suitable for precision applications requiring higher accuracy.

Q: Can TNPW080568K1BYEA replace RG2012N-6812-B-T1 in all applications?

A: TNPW080568K1BYEA is mechanically and electrically compatible with RG2012N-6812-B-T1 for most applications. The key differences are higher power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). The higher power rating provides additional thermal margin. Both parts maintain AEC-Q200 qualification and ROHS3 compliance.

Q: What is the significance of the T1 and T5 suffixes in Susumu part numbers?

A: The T1 and T5 suffixes indicate packaging format. T1 denotes bulk packaging, while T5 denotes Tape & Reel (TR) packaging. Electrical and mechanical specifications are identical between T1 and T5 variants. Selection depends on manufacturing process requirements and inventory management preferences.

Q: How does the temperature coefficient affect part selection?

A: Temperature coefficient (ppm/°C) specifies resistance change per degree Celsius. RG2012N-6812-B-T1 and most Susumu alternatives have ±10ppm/°C, while ERA-6AEB6812V has ±25ppm/°C. Lower temperature coefficients provide better stability across temperature ranges. For precision analog circuits, ±10ppm/°C is preferred. For general-purpose applications, ±25ppm/°C is acceptable.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed (RG2012N-6812-B-T5, RG2012N-6812-W-T1, RG2012N-6812-W-T5, TNPW080568K1BYEA, and ERA-6AEB6812V) carry AEC-Q200 automotive qualification, ensuring compatibility with automotive and high-reliability applications.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture exposure precautions. All parts listed have MSL 1 rating, meaning they do not require special moisture-controlled storage or handling procedures prior to assembly.
