Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-2801-W-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.8 kOhms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Automotive AEC-Q200 qualification
• RoHS3 compliance

Allowable Variation Parameters:

• Tolerance: Equal to or tighter than ±0.05%
• Temperature coefficient: Equal to or lower absolute value
• Operating temperature range: Equal to or wider than -55°C ~ 155°C
• Packaging format: Bulk or Tape & Reel (TR)
• Manufacturer: Susumu or qualified alternative manufacturers

Substitute parts are grouped into two categories:

Direct Susumu Equivalents: Parts from the RG series (RG2012P, RG2012V, RG2012N variants) that maintain identical electrical specifications with different packaging formats or enhanced performance characteristics.

Cross-Manufacturer Equivalent: The TNPU08052K80AZEN00 from Vishay Dale meets all mandatory electrical and mechanical parameters with equivalent AEC-Q200 automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

The RG2012P-2801-W-T5 provides direct functional equivalence to the obsolete RG2012P-2801-W-T1. Both parts maintain ±0.05% tolerance, ±25ppm/°C temperature coefficient, and identical operating temperature range. The primary difference is packaging format: RG2012P-2801-W-T5 is supplied in Tape & Reel format, standard for automated assembly processes. This part is active and in stock.

For Enhanced Performance (Tighter Tolerance):

The RG2012V-2801-P-T1 offers ±0.02% tolerance with ±5ppm/°C temperature coefficient, representing improved precision over the original specification. This part is suitable for applications requiring tighter resistance tolerances while maintaining full AEC-Q200 automotive qualification and identical package dimensions.

For Improved Temperature Stability:

The RG2012V-2801-W-T1 and RG2012V-2801-W-T5 both feature ±5ppm/°C temperature coefficient compared to the original ±25ppm/°C, providing superior temperature stability across the full -55°C to 155°C operating range. Both maintain ±0.05% tolerance and are available in Tape & Reel packaging.

The RG2012N-2801-W-T1 provides intermediate temperature stability at ±10ppm/°C with ±0.05% tolerance.

For Cross-Manufacturer Sourcing:

The TNPU08052K80AZEN00 from Vishay Dale is electrically equivalent with ±0.05% tolerance and ±5ppm/°C temperature coefficient. This part carries AEC-Q200 automotive qualification and moisture-resistant thin film construction. Operating temperature range is -55°C to 125°C, which is 30°C narrower than the Susumu parts. This part is suitable for applications not requiring the full 155°C upper temperature limit.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and 0805 package dimensions.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-2801-W-T5 be used as a direct replacement for RG2012P-2801-W-T1?

A: Yes. Both parts have identical electrical specifications: 2.8 kOhms ±0.05%, 0.125W power rating, ±25ppm/°C temperature coefficient, and -55°C to 155°C operating range. The difference is packaging format: RG2012P-2801-W-T1 is supplied in bulk, while RG2012P-2801-W-T5 is supplied in Tape & Reel format. RG2012P-2801-W-T5 is the active production equivalent.

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

A: The RG2012V series has a temperature coefficient of ±5ppm/°C, while the RG2012N series has ±10ppm/°C. Both maintain ±0.05% tolerance and identical operating temperature range. The RG2012V series provides superior temperature stability for precision applications.

Q: Can the RG2012V-2801-P-T1 replace the original RG2012P-2801-W-T1?

A: Yes. The RG2012V-2801-P-T1 has tighter tolerance (±0.02% versus ±0.05%), lower temperature coefficient (±5ppm/°C versus ±25ppm/°C), and identical operating temperature range. This represents an upgrade in performance characteristics while maintaining full compatibility with the 0805 package footprint and AEC-Q200 qualification.

Q: Is the TNPU08052K80AZEN00 suitable for all applications using RG2012P-2801-W-T1?

A: The TNPU08052K80AZEN00 is suitable for applications where the operating temperature does not exceed 125°C. The original part and Susumu equivalents support operation to 155°C. For applications requiring the full temperature range, Susumu parts are required. For applications within -55°C to 125°C, the Vishay Dale part is electrically and mechanically compatible.

Q: What does the "T1" and "T5" designation mean in Susumu part numbers?

A: The suffix indicates packaging format. "T1" denotes bulk packaging, while "T5" denotes Tape & Reel (TR) packaging. Electrical specifications are identical between T1 and T5 variants of the same base part number.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, meeting automotive reliability and quality standards. All parts are ROHS3 compliant and have MSL 1 (unlimited) moisture sensitivity rating.

Q: Can I use RG2012V-2801-W-T1 in place of RG2012P-2801-W-T1 without circuit redesign?

A: Yes. The RG2012V-2801-W-T1 is a direct mechanical and electrical substitute. It has identical resistance value, tolerance, power rating, and package dimensions. The improved temperature coefficient (±5ppm/°C versus ±25ppm/°C) provides better performance without requiring any circuit modifications.
