Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCU08050D1202BP100 are qualified based on the following criteria:

Electrical Parameters (Critical for Substitution):

• Resistance value: 12 kOhms (exact match required)
• Tolerance: ±0.1% or tighter (±0.05% acceptable as upgrade)
• Power rating: 0.125W minimum
• Composition: Thin film technology
• Temperature coefficient: ±25ppm/°C or better

Mechanical Parameters (Required for Board Compatibility):

• Package: 0805 (2012 Metric)
• Dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2
• Height seated (max): 0.022" to 0.024" (0.55mm to 0.60mm)

Compliance & Environmental:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Operating temperature range: -55°C minimum to 125°C minimum

Parts meeting all electrical and mechanical criteria are classified as direct substitutes. Parts with improved specifications (lower temperature coefficient, tighter tolerance, automotive qualification) are classified as upgrades.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Equivalent Performance):

ERA-6AEB123V, RG2012P-123-B-T5, and RT0805BRD0712KL are direct functional equivalents to the MCU08050D1202BP100. All three maintain the 12 kOhms ±0.1% specification, 0.125W power rating, and ±25ppm/°C temperature coefficient. These parts are Active status and RoHS3 compliant. Selection among these three depends on packaging preference (Cut Tape vs. Tape & Reel) and feature requirements. RG2012P-123-B-T5 includes anti-sulfur coating matching the original part's environmental protection.

Upgrade Options (Enhanced Specifications):

ERA-6APB123V, ERA-6ARB123V, and ERA-6ARW123V offer improved performance characteristics while maintaining full compatibility. ERA-6APB123V reduces temperature coefficient to ±15ppm/°C. ERA-6ARB123V further improves to ±10ppm/°C. ERA-6ARW123V provides the tightest tolerance at ±0.05% with ±10ppm/°C temperature coefficient, suitable for applications requiring enhanced precision. All three upgrades include Automotive AEC-Q200 qualification and extended operating temperature to 155°C. These parts are Active status and RoHS3 compliant.

All substitute and upgrade parts are available in Active status with unlimited moisture sensitivity rating (MSL 1), ensuring long-term storage and handling compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB123V replace MCU08050D1202BP100 directly on the PCB?

A: Yes. ERA-6AEB123V is a direct substitute with identical electrical specifications (12 kOhms ±0.1%, 0.125W, ±25ppm/°C) and mechanical compatibility (0805 package, 2.00mm x 1.25mm dimensions). The only difference is packaging format (Cut Tape & Digi-Reel vs. Tape & Reel) and extended operating temperature range (-55°C to 155°C vs. -55°C to 125°C), which does not affect board-level compatibility.

Q: What is the difference between direct substitutes and upgrade parts?

A: Direct substitutes (ERA-6AEB123V, RG2012P-123-B-T5, RT0805BRD0712KL) match all electrical and mechanical parameters of the original part. Upgrade parts (ERA-6APB123V, ERA-6ARB123V, ERA-6ARW123V) maintain compatibility but offer improved specifications such as lower temperature coefficient (±15ppm/°C or ±10ppm/°C) or tighter tolerance (±0.05%), making them suitable for higher-precision applications.

Q: Does the anti-sulfur feature of MCU08050D1202BP100 affect substitute selection?

A: The anti-sulfur feature is an environmental protection characteristic. RG2012P-123-B-T5 includes anti-sulfur coating. Other direct substitutes (ERA-6AEB123V, RT0805BRD0712KL) do not specify this feature but maintain equivalent electrical performance. Selection depends on application environment and corrosion resistance requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute and upgrade parts are RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original part's environmental compliance status.

Q: Can ERA-6ARW123V be used in place of MCU08050D1202BP100?

A: Yes. ERA-6ARW123V is mechanically and electrically compatible with enhanced specifications. It provides ±0.05% tolerance (tighter than the original ±0.1%) and ±10ppm/°C temperature coefficient (better than ±25ppm/°C). These improvements ensure full backward compatibility while offering superior precision performance.

Q: What packaging formats are available for these substitutes?

A: MCU08050D1202BP100, ERA-6APB123V, ERA-6ARB123V, and ERA-6ARW123V are supplied in Tape & Reel (TR) format. ERA-6AEB123V and RG2012P-123-B-T5 are supplied in Cut Tape (CT) & Digi-Reel format. Packaging selection depends on assembly process requirements and volume handling.

Q: Do substitute parts support the same operating temperature range?

A: MCU08050D1202BP100 operates from -55°C to 125°C. Direct substitutes ERA-6AEB123V, RG2012P-123-B-T5, and RT0805BRD0712KL, as well as all upgrade parts, extend the upper limit to 155°C. This extended range does not affect compatibility in applications operating within the original -55°C to 125°C specification.
