Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The Susumu RG2012N and RG2012V series parts provide direct substitution with improved specifications. All listed Susumu alternatives maintain AEC-Q200 automotive qualification, anti-sulfur construction, and ROHS3 compliance. Selection between these parts depends on tolerance and temperature coefficient requirements:

• RG2012N-1741-B-T5 and RG2012N-1741-W-T5 / RG2012N-1741-W-T1: Offer tighter tolerance (±0.1% or ±0.05%) while maintaining the ±10ppm/°C temperature coefficient of the original part. These are active products with established supply availability.

• RG2012V Series (RG2012V-1741-B-T5, RG2012V-1741-P-T1, RG2012V-1741-W-T1, RG2012V-1741-W-T5): Provide superior temperature coefficient performance at ±5ppm/°C with tolerance options ranging from ±0.02% to ±0.1%. These parts are active and suitable for applications requiring enhanced thermal stability.

Alternative Manufacturer Substitute:

The TNPW08051K74BYEA from Vishay Dale is an active alternative that maintains the 1.74 kOhms resistance, ±0.1% tolerance, and AEC-Q200 qualification. This part offers increased power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). The TNPW08051K74BYEA is suitable for applications where higher power dissipation capability or wider temperature operation is beneficial.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, AEC-Q200 automotive qualification, anti-sulfur construction, and MSL 1 (Unlimited) moisture sensitivity rating. All parts are available in Tape & Reel packaging format.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-1741-C-T5 be directly replaced with any of the listed substitutes?

A: Yes. All listed substitute parts are electrically and mechanically compatible. They share the same 1.74 kOhms resistance value, 0805 package, thin film composition, anti-sulfur construction, and AEC-Q200 automotive qualification. The substitutes offer equal or improved tolerance and temperature coefficient specifications.

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

A: The primary difference is temperature coefficient. RG2012N series parts have ±10ppm/°C temperature coefficient, while RG2012V series parts have ±5ppm/°C temperature coefficient. Both series maintain identical resistance values, package types, and automotive qualifications. RG2012V selection is appropriate for applications requiring superior thermal stability.

Q: Why does TNPW08051K74BYEA have a higher power rating (0.26W) than the original part (0.125W)?

A: The TNPW08051K74BYEA is a different product line from Vishay Dale with enhanced power dissipation capability. The higher power rating does not affect compatibility; it provides additional design margin for applications with higher current requirements. The part maintains the same 1.74 kOhms resistance, ±0.1% tolerance, and 0805 package format.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, matching the original part's packaging format. This ensures compatibility with standard automated assembly equipment.

Q: What tolerance should I select if the original design specification requires ±0.25% tolerance?

A: Any substitute part with tolerance equal to or tighter than ±0.25% is acceptable. Options include ±0.1% (RG2012N-1741-B-T5, RG2012V-1741-B-T5, TNPW08051K74BYEA), ±0.05% (RG2012N-1741-W-T1, RG2012N-1741-W-T5, RG2012V-1741-W-T1, RG2012V-1741-W-T5), or ±0.02% (RG2012V-1741-P-T1). Tighter tolerance provides improved circuit accuracy without affecting mechanical or electrical compatibility.

Q: Is the extended operating temperature range of TNPW08051K74BYEA (-55°C ~ 175°C) a compatibility concern?

A: No. The extended temperature range is a specification enhancement that does not affect compatibility. If the original design operates within -55°C ~ 155°C, the TNPW08051K74BYEA will function correctly within this range. The extended range provides additional design margin for future applications.

Q: Can I use RG2012V-1741-P-T1 with ±0.02% tolerance in place of the original ±0.25% part?

A: Yes. The ±0.02% tolerance is tighter than the original ±0.25% specification, making it a direct upgrade. The part maintains all other electrical and mechanical parameters, including resistance value, power rating, package type, and automotive qualifications. The improved tolerance provides enhanced circuit precision.
