Engineering Selection Recommendations
Primary Substitutes (Susumu RG Series - Active Status):
The Susumu RG2012N and RG2012V series parts provide direct substitution with improved specifications. All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and identical 0805 package geometry.
RG2012N Series (±10ppm/°C Temperature Coefficient):
- RG2012N-4641-B-T5: Tighter tolerance (±0.1%) with active product status
- RG2012N-4641-W-T1 and RG2012N-4641-W-T5: Highest tolerance precision (±0.05%) within N-series
RG2012V Series (±5ppm/°C Temperature Coefficient):
- RG2012V-4641-B-T5: ±0.1% tolerance with improved temperature stability
- RG2012V-4641-P-T1: Highest precision option (±0.02%) with superior temperature coefficient
- RG2012V-4641-W-T1 and RG2012V-4641-W-T5: ±0.05% tolerance with enhanced temperature performance
Alternative Manufacturer:
TNPW08054K64BYEA (Vishay Dale TNPW e3 series) provides equivalent substitution with extended operating temperature range (-55°C to 175°C) and higher power rating (0.26W). This part maintains AEC-Q200 qualification and ROHS3 compliance with ±0.1% tolerance and ±10ppm/°C temperature coefficient.
Selection Basis:
All substitute parts are active products with established supply chains. Selection between Susumu and Vishay alternatives depends on application requirements for temperature coefficient precision and maximum operating temperature.

The Vishay TNPW option provides higher power dissipation capability if thermal margin is required.
Frequently Asked Questions (FAQ)
Q: Can RG2012N-4641-B-T5 directly replace RG2012N-4641-C-T5?
A: Yes. Both parts share identical resistance (4.64 kOhms), package (0805), power rating (0.125W), and operating temperature range (-55°C to 155°C). RG2012N-4641-B-T5 provides tighter tolerance (±0.1% versus ±0.25%) and is an active product with established supply availability.
Q: What is the difference between RG2012N and RG2012V series?
A: The primary difference is temperature coefficient. RG2012N series has ±10ppm/°C while RG2012V series has ±5ppm/°C. Both series maintain identical resistance, package, power rating, and operating temperature range. RG2012V provides superior temperature stability for precision applications.
Q: Is the Vishay TNPW08054K64BYEA compatible with the original part?
A: Yes, with noted differences. TNPW08054K64BYEA maintains identical resistance (4.64 kOhms), package (0805), and tolerance (±0.1%). It provides higher power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C to 175°C). Both parts carry AEC-Q200 qualification and ROHS3 compliance.
Q: Why is the original RG2012N-4641-C-T5 marked obsolete?
A: Obsolescence reflects manufacturer discontinuation. Active substitute parts from Susumu's RG2012N and RG2012V series provide equivalent or superior performance with continued supply availability and support.
Q: Can I use a substitute part with tighter tolerance (±0.05% or ±0.02%) in place of the ±0.25% original?
A: Yes. Tighter tolerance specifications are acceptable substitutions. Parts with ±0.05% or ±0.02% tolerance will perform within the original ±0.25% specification window while providing improved accuracy for precision circuit applications.
Q: What packaging format should I specify for procurement?
A: The original part was supplied in bulk format. All active substitute parts are available in Tape & Reel (TR) packaging, which is standard for automated assembly processes. Confirm packaging compatibility with your manufacturing process requirements.
Q: Are all substitute parts AEC-Q200 qualified?
A: Yes. All listed substitute parts maintain AEC-Q200 automotive qualification, meeting the same reliability and quality standards as the original RG2012N-4641-C-T5.
