Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Tolerance ±0.1%):

RG2012N-2372-B-T5 is the primary direct equivalent from Susumu. This part maintains all electrical and mechanical specifications of the RG2012N-2372-B-T1 while offering active product status and improved supply chain availability. The only difference is packaging format (Tape & Reel), which is standard for current production.

ERA-6AEB2372V from Panasonic Electronic Components is a qualified direct equivalent. This part maintains the ±0.1% tolerance and all AEC-Q200 automotive specifications. The temperature coefficient is ±25ppm/°C compared to ±10ppm/°C in the original part. This part offers significantly higher inventory availability (19,039 units in stock).

TNPW080523K7BYEA from Vishay Dale is a qualified direct equivalent with enhanced power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C to 175°C). This part provides additional thermal margin and is suitable for applications requiring higher power dissipation capability.

Upgrade Equivalents (Improved Tolerance ±0.05%):

RG2012N-2372-W-T1 and RG2012N-2372-W-T5 from Susumu offer tighter tolerance specification (±0.05%) while maintaining all other parameters. These parts are suitable for applications requiring higher precision than the original ±0.1% specification. Both are active products with good availability.

Selection Criteria:

For direct replacement in existing designs, select RG2012N-2372-B-T5 to maintain identical specifications with active product status. For applications requiring higher precision, select RG2012N-2372-W-T1 or RG2012N-2372-W-T5. For maximum supply availability and extended temperature range, select ERA-6AEB2372V or TNPW080523K7BYEA respectively. All substitute parts maintain AEC-Q200 automotive qualification and RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-2372-B-T5 be used as a direct replacement for RG2012N-2372-B-T1?

A: Yes. RG2012N-2372-B-T5 is a direct equivalent with identical electrical specifications (23.7 kOhms ±0.1%, 0.125W, ±10ppm/°C) and mechanical package (0805). The only difference is packaging format (Tape & Reel), which is standard for active production. Both parts are Susumu RG series thin film resistors with AEC-Q200 qualification.

Q: What is the difference between the RG2012N-2372-B-T1 and RG2012N-2372-W-T1?

A: The primary difference is tolerance specification. The RG2012N-2372-W-T1 offers ±0.05% tolerance compared to ±0.1% in the RG2012N-2372-B-T1. All other parameters including resistance value, power rating, package, temperature coefficient, and operating temperature range are identical. The W-series provides higher precision for applications requiring tighter tolerance control.

Q: Are cross-manufacturer substitutes available?

A: Yes. ERA-6AEB2372V (Panasonic) and TNPW080523K7BYEA (Vishay Dale) are qualified substitutes from alternative manufacturers. Both maintain the 23.7 kOhms resistance value, ±0.1% tolerance, 0805 package, and AEC-Q200 automotive qualification. ERA-6AEB2372V has higher inventory availability. TNPW080523K7BYEA offers higher power rating (0.26W) and extended temperature range (-55°C to 175°C).

Q: What is the significance of the packaging designation (T1 versus T5)?

A: The T1 and T5 designations refer to packaging format and tape specifications. T1 and T5 both indicate Tape & Reel packaging suitable for automated assembly. These designations do not affect electrical performance or mechanical compatibility. Selection between T1 and T5 is based on equipment compatibility and supply availability.

Q: Can TNPW080523K7BYEA be used in place of RG2012N-2372-B-T1?

A: Yes. TNPW080523K7BYEA is a qualified substitute with identical resistance (23.7 kOhms), tolerance (±0.1%), package (0805), and AEC-Q200 rating. The TNPW part offers higher power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C to 175°C versus -55°C to 155°C). These are performance enhancements suitable for applications requiring additional thermal margin.

Q: Is the temperature coefficient difference between ERA-6AEB2372V (±25ppm/°C) and RG2012N-2372-B-T1 (±10ppm/°C) significant?

A: The temperature coefficient difference is a measurable parameter. ERA-6AEB2372V has a higher temperature coefficient (±25ppm/°C) compared to the original part (±10ppm/°C). For applications operating across the full temperature range (-55°C to 155°C), this results in greater resistance variation. ERA-6AEB2372V is suitable for applications where this level of temperature stability is acceptable. For applications requiring the original ±10ppm/°C specification, select RG2012N-2372-B-T5, RG2012N-2372-W-T1, RG2012N-2372-W-T5, or TNPW080523K7BYEA.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (RG2012N-2372-B-T5, RG2012N-2372-W-T1, RG2012N-2372-W-T5, ERA-6AEB2372V, and TNPW080523K7BYEA) are RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All parts maintain compliance with automotive AEC-Q200 qualification.
