Engineering Selection Recommendations

RG2012P-4322-W-T5 (Direct Packaging Substitute)

The RG2012P-4322-W-T5 is a direct electrical equivalent to the RG2012P-4322-W-T1, manufactured by Susumu with identical specifications. The primary difference is packaging format: the RG2012P-4322-W-T5 is supplied in Tape & Reel format versus bulk packaging. This part is currently active in production and maintains all electrical, thermal, and compliance characteristics of the original component. Selection of this part eliminates obsolescence risk while preserving exact performance parameters.

RG2012N-4322-W-T1 (Enhanced Temperature Coefficient)

The RG2012N-4322-W-T1 is an active Susumu product offering improved temperature stability with a ±10ppm/°C coefficient compared to the ±25ppm/°C of the original part. All other electrical specifications, package dimensions, and automotive qualifications remain identical. This part is supplied in Tape & Reel format. Selection of this part provides superior temperature performance while maintaining full compatibility with the original design.

TNPU080543K2AZEN00 (Cross-Manufacturer Equivalent)

The TNPU080543K2AZEN00 is manufactured by Vishay Dale and provides equivalent electrical performance with a superior temperature coefficient of ±5ppm/°C. This part includes moisture-resistant coating in addition to anti-sulfur protection. The operating temperature range extends to 125°C maximum, which is 30°C lower than the original specification. This part is supplied in Tape & Reel format and is currently active. Selection of this part is appropriate for applications where the maximum operating temperature does not exceed 125°C and where enhanced temperature stability is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the RG2012P-4322-W-T5 be used as a direct replacement for the RG2012P-4322-W-T1?

A: Yes. The RG2012P-4322-W-T5 is electrically and mechanically identical to the RG2012P-4322-W-T1. The only difference is the packaging format (Tape & Reel versus bulk). Both parts share the same resistance value, tolerance, power rating, package dimensions, and automotive qualifications.

Q: What is the difference between the RG2012N-4322-W-T1 and the RG2012P-4322-W-T1?

A: The RG2012N-4322-W-T1 has a temperature coefficient of ±10ppm/°C compared to ±25ppm/°C for the RG2012P-4322-W-T1. This means the RG2012N-4322-W-T1 exhibits superior stability across temperature variations. All other specifications, including resistance, tolerance, power rating, and package format, are identical.

Q: Is the TNPU080543K2AZEN00 suitable for all applications using the RG2012P-4322-W-T1?

A: The TNPU080543K2AZEN00 is suitable for applications where the maximum operating temperature does not exceed 125°C. The original RG2012P-4322-W-T1 is rated to 155°C. If your application requires operation above 125°C, the TNPU080543K2AZEN00 is not appropriate. For applications operating at or below 125°C, this part provides equivalent performance with enhanced temperature coefficient stability.

Q: What does the packaging designation "Tape & Reel" mean?

A: Tape & Reel (TR) is an automated packaging format where components are mounted on a continuous carrier tape wound on a reel. This format is standard for high-volume manufacturing and automated assembly processes. Bulk packaging refers to components supplied loose or in trays. Both formats contain identical components; the difference is in handling and assembly methodology.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed—RG2012P-4322-W-T5, RG2012N-4322-W-T1, and TNPU080543K2AZEN00—carry AEC-Q200 automotive qualification. This certification confirms compliance with automotive reliability and quality standards.

Q: What is the significance of the ±0.05% tolerance specification?

A: The ±0.05% tolerance indicates the maximum allowable deviation from the nominal 43.2 kOhms resistance value. This is a precision tolerance specification. All substitute parts maintain this same tolerance, ensuring consistent performance in precision circuit applications.

Q: Can I mix different substitute parts in the same design?

A: Yes, provided your circuit design accommodates the allowable variations in temperature coefficient. If your design is sensitive to temperature coefficient performance, use parts with matching or superior specifications. The RG2012N-4322-W-T1 and TNPU080543K2AZEN00 offer improved temperature stability compared to the original RG2012P-4322-W-T1.
