Engineering Selection Recommendations
Direct Equivalent (Same Specifications):
RG2012P-1073-B-T5 (Susumu) is the direct equivalent replacement for the obsolete RG2012P-1073-B-T1. Both components share identical electrical specifications: 107 kOhms ±0.1% tolerance, 0.125W power rating, ±25ppm/°C temperature coefficient, and automotive AEC-Q200 qualification. The primary difference is packaging format (Tape & Reel vs. bulk), which does not affect electrical performance. This part is currently in active production status with 745 units in stock.
ERA-6AEB1073V (Panasonic) provides direct electrical equivalence with identical resistance, tolerance, power rating, and temperature coefficient. This component maintains AEC-Q200 automotive qualification and ROHS3 compliance. Panasonic ERA-6A series offers high inventory availability (14,033 units) and active production status.

Frequently Asked Questions (FAQ)
Q: Can RG2012P-1073-B-T5 be used as a direct replacement for RG2012P-1073-B-T1?
A: Yes. RG2012P-1073-B-T5 is the direct equivalent replacement. Both components have identical electrical specifications: 107 kOhms ±0.1%, 0.125W power rating, ±25ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. The only difference is packaging format (Tape & Reel), which does not affect circuit performance.
Q: What is the difference between the "B" and "W" designations in Susumu part numbers?
A: The "B" designation indicates ±0.1% tolerance, while "W" indicates ±0.05% tolerance. The "W" series provides tighter tolerance specifications for precision applications. Both maintain identical package dimensions and power ratings.
Q: Are non-AEC-Q200 parts acceptable substitutes?
A: Non-AEC-Q200 parts such as RT0805BRD07107KL and RP73D2A107KBTDF meet all electrical and mechanical specifications but lack automotive qualification. These parts are acceptable only if the application does not require automotive-grade reliability certification. Original design specifications should be reviewed to determine if AEC-Q200 qualification is mandatory.
Q: Can parts with higher power ratings (0.25W or 0.26W) be used in place of the 0.125W original?
A: Yes. Higher power-rated components (9-2176093-7, TNPW0805107KBEEA, TNPW0805107KBEEN) are physically compatible and electrically equivalent. The increased power rating provides additional thermal margin and does not negatively affect circuit operation. Physical dimensions remain within 0805 package specifications.
Q: What is the significance of temperature coefficient values?
A: Temperature coefficient (ppm/°C) indicates how much the resistance value changes per degree Celsius. Lower values represent better stability. The original part has ±25ppm/°C; upgraded alternatives with ±10ppm/°C or ±15ppm/°C provide superior temperature stability, reducing resistance drift in temperature-sensitive applications.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the environmental compliance status of the original RG2012P-1073-B-T1.
Q: What is Moisture Sensitivity Level (MSL) 1?
A: MSL 1 indicates unlimited shelf life without moisture exposure precautions. All listed parts carry MSL 1 rating, requiring no special moisture control during storage or handling.
Q: Can ERA-6AEB1073V be used in automotive applications?
A: Yes. ERA-6AEB1073V carries AEC-Q200 automotive qualification, making it suitable for automotive applications. This part is functionally equivalent to the original RG2012P-1073-B-T1 for automotive use.
Q: What is the difference between TNPW0805107KBEEA and TNPW0805107KBEEN?
A: Both parts are electrically and mechanically identical with 107 kOhms ±0.1%, 0.26W power rating, and ±25ppm/°C temperature coefficient. The difference is in packaging or tape configuration. Both are suitable substitutes with equivalent performance.
Q: Is the extended temperature range (-55°C to 175°C) of TNPW series beneficial?
A: The extended upper temperature limit of 175°C (versus 155°C for the original) provides additional thermal margin in high-temperature environments. This is beneficial for applications operating near the upper temperature limit but is not required if the original 155°C specification is sufficient.
