Engineering Selection Recommendations

Susumu RG Series (N-suffix variants): The RG2012N-8661-B-T5, RG2012N-8661-W-T1, and RG2012N-8661-W-T5 are direct Susumu replacements maintaining the same temperature coefficient (±10ppm/°C) as the original part. These components are active products with improved tolerance specifications (±0.1% and ±0.05% respectively) while preserving all electrical and mechanical compatibility. Selection among these three depends on tolerance requirements for the application.

Susumu RG Series (V-suffix variants): The RG2012V-8661-B-T5, RG2012V-8661-P-T1, RG2012V-8661-W-T1, and RG2012V-8661-W-T5 represent enhanced performance alternatives from Susumu. These parts feature improved temperature coefficient (±5ppm/°C) compared to the original ±10ppm/°C specification, providing superior temperature stability. Tolerance options range from ±0.02% to ±0.1%. All V-suffix variants are active products suitable for applications requiring tighter temperature performance.

Vishay Dale TNPW08058K66BYEA: The TNPW08058K66BYEA from Vishay Dale offers cross-manufacturer compatibility with enhanced power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). This part maintains ±0.1% tolerance and AEC-Q200 automotive qualification. The higher power rating provides additional design margin in applications where thermal dissipation is a consideration.

All listed substitutes are ROHS3 compliant, AEC-Q200 rated, and feature anti-sulfur construction with MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-8661-B-T5 directly replace RG2012N-8661-C-T5?

A: Yes. The RG2012N-8661-B-T5 is a direct replacement with identical electrical and mechanical specifications except for improved tolerance (±0.1% versus ±0.25%). Both parts share the same resistance value, power rating, package, temperature coefficient, and operating range. The tighter tolerance of the substitute part is compatible with applications designed for the original part.

Q: What is the difference between RG2012N and RG2012V series?

A: The primary difference is temperature coefficient. RG2012N variants have ±10ppm/°C temperature coefficient, while RG2012V variants have ±5ppm/°C. The V-series provides superior temperature stability. Both series maintain identical resistance, power rating, package, and AEC-Q200 qualification.

Q: Is TNPW08058K66BYEA suitable for applications designed for RG2012N-8661-C-T5?

A: Yes, with consideration of the higher power rating. The TNPW08058K66BYEA maintains the same 8.66 kOhms resistance, 0805 package, AEC-Q200 rating, and anti-sulfur construction. The 0.26W power rating (versus 0.125W) and extended temperature range (-55°C ~ 175°C) represent improvements. The ±0.1% tolerance is tighter than the original ±0.25%.

Q: Can I use a substitute part with tighter tolerance than the original specification?

A: Yes. A substitute part with tighter tolerance (lower percentage value) is fully compatible with applications designed for the original part. Tighter tolerance represents improved performance and does not create compatibility issues.

Q: What packaging format should I specify for procurement?

A: All active substitute parts are available in Tape & Reel (TR) packaging format, which is the standard for production procurement. The original obsolete part was supplied in bulk format; TR packaging is the current industry standard for equivalent components.

Q: Are all substitute parts automotive-qualified?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification, matching the original part's rating. All are ROHS3 compliant and feature anti-sulfur construction with MSL 1 moisture sensitivity rating.

Q: Which substitute offers the best temperature stability?

A: The RG2012V-8661-P-T1 offers the best combination of temperature stability (±5ppm/°C) and tolerance (±0.02%). For applications requiring only improved temperature coefficient without the tightest tolerance, the RG2012V series variants with ±5ppm/°C are suitable alternatives.
