Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-304-W-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 300 kOhms
• Tolerance: ±0.05%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Automotive AEC-Q200 qualification
• RoHS3 compliance

Allowable Variation Parameters:

• Temperature coefficient (±25ppm/°C, ±10ppm/°C, or ±5ppm/°C)
• Operating temperature range (minimum -55°C, maximum up to 155°C or 125°C)
• Packaging format (Tape & Reel acceptable for direct substitution)
• Manufacturer (Susumu or equivalent qualified suppliers)
• Product status (Active preferred over Obsolete)

Substitute parts must maintain identical electrical specifications for resistance, tolerance, and power rating. Physical package dimensions and termination count must remain consistent. All substitutes must retain automotive-grade qualification and environmental compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred): RG2012P-304-W-T5 is the primary direct substitute for RG2012P-304-W-T1. Both components are manufactured by Susumu with identical electrical specifications, temperature coefficient, and operating temperature range. The RG2012P-304-W-T5 is currently in active production status with substantial inventory availability (9900 Pcs), ensuring supply chain continuity. The only difference is packaging format (Tape & Reel versus bulk), which does not affect electrical or mechanical compatibility.

Enhanced Performance Alternative: RG2012N-304-W-T5 offers improved temperature stability with a ±10ppm/°C coefficient compared to the original ±25ppm/°C specification. This Susumu component maintains all other electrical and mechanical parameters while providing superior precision characteristics. Active production status and adequate inventory (1197 Pcs) support design implementation.

Cross-Manufacturer Substitute: TNPU0805300KAZEN00 (Vishay Dale) provides functional equivalence with additional moisture-resistant coating. This component features the tightest temperature coefficient (±5ppm/°C) among available substitutes. The maximum seated height is 0.022" (0.55mm) compared to 0.020" (0.50mm) for Susumu parts, and the upper operating temperature limit is 125°C rather than 155°C. These dimensional and thermal differences require design verification for space-constrained or high-temperature applications.

All substitute parts maintain AEC-Q200 automotive qualification, anti-sulfur coating, RoHS3 compliance, and MSL 1 moisture sensitivity rating, ensuring compatibility with existing reliability and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-304-W-T5 be used as a direct replacement for RG2012P-304-W-T1?

A: Yes. Both components share identical electrical specifications (300 kOhms ±0.05%, 0.125W), package dimensions (0805 / 2012 Metric), temperature coefficient (±25ppm/°C), and operating range (-55°C ~ 155°C). The difference in packaging format (Tape & Reel versus bulk) does not affect electrical or mechanical compatibility. RG2012P-304-W-T5 is the recommended substitute due to active production status.

Q: What is the difference between RG2012P-304-W-T5 and RG2012N-304-W-T5?

A: The primary difference is temperature coefficient: RG2012P-304-W-T5 has ±25ppm/°C while RG2012N-304-W-T5 has ±10ppm/°C. Both maintain identical resistance (300 kOhms), tolerance (±0.05%), power rating (0.125W), and package specifications. RG2012N-304-W-T5 provides superior temperature stability for precision applications requiring tighter tolerance maintenance across the operating range.

Q: Is TNPU0805300KAZEN00 compatible with designs using RG2012P-304-W-T1?

A: TNPU0805300KAZEN00 is electrically compatible with identical resistance, tolerance, and power specifications. However, two physical differences require consideration: maximum seated height is 0.022" (0.55mm) versus 0.020" (0.50mm), and the upper operating temperature limit is 125°C versus 155°C. Applications with space constraints or operating above 125°C require design verification before substitution.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. RG2012P-304-W-T5, RG2012N-304-W-T5, and TNPU0805300KAZEN00 all carry AEC-Q200 automotive qualification, meeting the same reliability standards as the original RG2012P-304-W-T1.

Q: What is the moisture sensitivity level for these components?

A: All listed components, including the original and all substitutes, have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Can these resistors be used in high-temperature applications above 125°C?

A: RG2012P-304-W-T5 and RG2012N-304-W-T5 are rated to 155°C and support high-temperature applications. TNPU0805300KAZEN00 is limited to 125°C maximum operating temperature and is not suitable for applications requiring operation above this threshold.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RG2012P-304-W-T5, RG2012N-304-W-T5, and TNPU0805300KAZEN00 are all ROHS3 compliant, maintaining environmental compliance equivalent to the original component.
