Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-1872-C-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 18.7 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (physical and electrical footprint compatibility)
• Composition: Thin Film (electrical performance characteristics)
• Automotive AEC-Q200 rating (quality and reliability standard)
• RoHS3 compliance (regulatory requirement)
• Moisture Sensitivity Level 1 (handling and storage compatibility)

Allowable Variation Parameters:

• Tolerance: Can be equal to or tighter (lower) than ±0.25%
• Power Rating: Can be equal to or higher than 0.125W
• Operating Temperature Range: Can be equal to or wider than -55°C ~ 155°C
• Temperature Coefficient: Must remain ±10ppm/°C

All identified substitute parts maintain the mandatory compatibility parameters while offering improved tolerance specifications and active product status.

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The Susumu RG2012N-1872-B-T5, RG2012N-1872-W-T1, and RG2012N-1872-W-T5 are direct substitutes from the same manufacturer series. All three parts maintain identical mechanical compatibility, electrical performance characteristics, and automotive AEC-Q200 certification. These parts offer improved tolerance specifications (±0.1% and ±0.05% respectively) compared to the original ±0.25%, while maintaining the same power rating and operating temperature range. All three are classified as active products with current manufacturing status.

Secondary Substitute (Vishay Dale TNPW080518K7BYEA):

The Vishay Dale TNPW080518K7BYEA provides cross-manufacturer substitution capability. This part maintains identical resistance, tolerance (±0.1%), package, composition, and AEC-Q200 certification. The TNPW080518K7BYEA offers an extended operating temperature range (-55°C ~ 175°C) and increased power rating (0.26W) compared to the original specification. This part is classified as active with current manufacturing status and includes moisture-resistant coating in addition to anti-sulfur protection.

All substitute parts are ROHS3 compliant, maintain Moisture Sensitivity Level 1, and are suitable for direct replacement in applications requiring the RG2012N-1872-C-T5.

Frequently Asked Questions (FAQ)

Q: Can the RG2012N-1872-B-T5 be used as a direct replacement for the RG2012N-1872-C-T5?

A: Yes. The RG2012N-1872-B-T5 maintains identical resistance (18.7 kOhms), package (0805), power rating (0.125W), and operating temperature range (-55°C ~ 155°C). The improved tolerance specification (±0.1% versus ±0.25%) provides enhanced accuracy without affecting compatibility. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance.

Q: What is the difference between the RG2012N-1872-W-T1 and RG2012N-1872-W-T5?

A: Both parts are identical in all electrical and mechanical parameters. The difference lies in packaging and tape configuration (T1 versus T5 designations). Both offer ±0.05% tolerance, which is tighter than the original ±0.25%. Selection between these parts depends on tape reel specifications required by manufacturing equipment.

Q: Is the Vishay Dale TNPW080518K7BYEA suitable for applications with higher temperature requirements?

A: The TNPW080518K7BYEA operates across -55°C ~ 175°C, extending 20°C above the original part's upper limit of 155°C. This part is suitable for applications requiring the extended temperature range. The increased power rating (0.26W versus 0.125W) provides additional thermal margin in power-dissipation-limited applications.

Q: Are all substitute parts automotive-qualified?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification, matching the original RG2012N-1872-C-T5 specification. This certification ensures compliance with automotive reliability and quality standards.

Q: What is the significance of the ±10ppm/°C temperature coefficient across all parts?

A: The temperature coefficient specifies resistance change per degree Celsius of temperature variation. All parts, including the original and substitutes, maintain identical ±10ppm/°C performance, ensuring consistent circuit behavior across the operating temperature range.

Q: Can the higher power-rated TNPW080518K7BYEA be used in space-constrained applications?

A: The TNPW080518K7BYEA maintains the same 0805 (2012 Metric) package footprint as the original part. The maximum seated height is 0.022" (0.55mm) compared to 0.020" (0.50mm) for the original. This 0.05mm difference is negligible for most applications but should be verified for height-critical PCB designs.

Q: Are all parts RoHS3 compliant?

A: Yes. All parts listed, including the original RG2012N-1872-C-T5 and all substitutes, are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.
