Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-2941-W-T1 is determined by the following critical parameters:

Electrical Parameters:

• Resistance value: 2.94 kOhms (exact match required)
• Tolerance: ±0.05% or tighter (lower tolerance values are acceptable upgrades)
• Power rating: 0.125W minimum
• Temperature coefficient: ±25ppm/°C or better (lower values represent improved stability)

Mechanical Parameters:

• Package type: 0805 (2012 Metric) only
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Height seated maximum: 0.020" (0.50mm) or less

Compliance & Environmental:

• AEC-Q200 automotive qualification (required)
• Anti-sulfur coating (required)
• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)
• Operating temperature range: -55°C minimum to 155°C maximum (or compatible subset)

Packaging Format:

• Original part uses bulk packaging; substitutes may use Tape & Reel (TR) format for active production parts

Substitute parts are grouped into three categories: Direct Substitutes (identical electrical and mechanical specifications with different packaging), Upgrade Substitutes (improved temperature coefficient or tolerance), and Similar Substitutes (alternative manufacturer with compatible specifications).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Identical Electrical Performance):

RG2012P-2941-W-T5 is the direct substitute for RG2012P-2941-W-T1. Both parts share identical electrical specifications (2.94 kΩ, ±0.05% tolerance, ±25ppm/°C temperature coefficient, -55°C to 155°C operating range). The only difference is packaging format: the original uses bulk packaging while the substitute uses Tape & Reel format. Both are Susumu RG series components with active product status, AEC-Q200 qualification, anti-sulfur coating, and ROHS3 compliance.

Upgrade Substitution (Improved Specifications):

RG2012N-2941-W-T1, RG2012V-2941-W-T1, RG2012V-2941-W-T5, and RG2012V-2941-P-T1 offer improved temperature coefficient performance compared to the original part. RG2012N-2941-W-T1 provides ±10ppm/°C stability. RG2012V series parts provide ±5ppm/°C stability, with RG2012V-2941-P-T1 additionally offering tighter tolerance at ±0.02%. All upgrade substitutes maintain the same resistance value, power rating, package type, and automotive qualification. All are active Susumu products with ROHS3 compliance.

Alternative Manufacturer Substitution:

TNPU08052K94AZEN00 (Vishay Dale TNPU e3 series) provides equivalent electrical performance with 2.94 kΩ resistance, ±0.05% tolerance, and ±5ppm/°C temperature coefficient. This part is AEC-Q200 qualified with anti-sulfur and moisture-resistant coating. The operating temperature range is -55°C to 125°C, which is narrower than the original part's -55°C to 155°C range. Physical dimensions are compatible (0805 package), with maximum seated height of 0.022" (0.55mm) compared to the original 0.020" (0.50mm). This part is active and ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-2941-W-T5 be used as a direct replacement for RG2012P-2941-W-T1?

A: Yes. RG2012P-2941-W-T5 is electrically and mechanically identical to RG2012P-2941-W-T1. The difference is packaging format: bulk versus Tape & Reel. Both parts have identical resistance (2.94 kΩ), tolerance (±0.05%), power rating (0.125W), temperature coefficient (±25ppm/°C), and operating range (-55°C to 155°C). Both are AEC-Q200 qualified Susumu components.

Q: What is the advantage of using RG2012V-2941-W-T1 instead of the original RG2012P-2941-W-T1?

A: RG2012V-2941-W-T1 provides superior temperature stability with a temperature coefficient of ±5ppm/°C compared to the original ±25ppm/°C. All other electrical parameters remain identical. This upgrade is beneficial for applications requiring tighter frequency or resistance stability across the operating temperature range.

Q: Is TNPU08052K94AZEN00 fully compatible with RG2012P-2941-W-T1?

A: TNPU08052K94AZEN00 is mechanically and electrically compatible for most applications. Both parts share the same resistance value (2.94 kΩ), tolerance (±0.05%), power rating (0.125W), package type (0805), and AEC-Q200 qualification. The Vishay Dale part has a narrower operating temperature range (-55°C to 125°C versus -55°C to 155°C) and slightly greater seated height (0.022" versus 0.020"). Applications requiring operation above 125°C require the Susumu part.

Q: Can I use RG2012V-2941-P-T1 as a substitute?

A: Yes. RG2012V-2941-P-T1 is a compatible upgrade with tighter tolerance (±0.02% versus ±0.05%) and superior temperature coefficient (±5ppm/°C versus ±25ppm/°C). All mechanical parameters and package type are identical. This part is suitable for applications requiring higher precision and stability.

Q: What is the difference between Tape & Reel and bulk packaging?

A: Tape & Reel (TR) packaging is the standard format for automated assembly processes, with components wound on continuous tape for pick-and-place equipment. Bulk packaging is loose component format. Electrically and mechanically, the parts are identical. Tape & Reel format is standard for active production parts.

Q: Does the Vishay Dale TNPU08052K94AZEN00 have the same anti-sulfur properties?

A: Yes. TNPU08052K94AZEN00 includes anti-sulfur coating and adds moisture-resistant properties. Both the original Susumu part and the Vishay Dale substitute are AEC-Q200 qualified with anti-sulfur coating and Moisture Sensitivity Level 1.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (RG2012P-2941-W-T5, RG2012N-2941-W-T1, RG2012V-2941-W-T1, RG2012V-2941-W-T5, RG2012V-2941-P-T1, and TNPU08052K94AZEN00) are ROHS3 compliant, matching the original part's environmental compliance status.
