Frequently Asked Questions (FAQ)

Q: Can RG2012P-7872-W-T5 be used as a direct replacement for RG2012P-7872-W-T1?

A: Yes. The RG2012P-7872-W-T5 is electrically and mechanically equivalent to the RG2012P-7872-W-T1. Both components feature identical resistance (78.7 kOhms), tolerance (±0.05%), power rating (0.125W), package (0805), and temperature coefficient (±25ppm/°C). The only difference is packaging format and product status. Direct substitution is valid for all applications.

Q: What is the difference between RG2012P-7872-W-T5 and RG2012N-7872-W-T1?

A: The primary difference is temperature coefficient. RG2012P-7872-W-T5 has a temperature coefficient of ±25ppm/°C, while RG2012N-7872-W-T1 has ±10ppm/°C. The RG2012N-7872-W-T1 provides superior temperature stability. All other parameters, including resistance, tolerance, power rating, and package, are identical. Both are active products available in Tape & Reel packaging.

Q: Why is the main part RG2012P-7872-W-T1 marked as obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued production of this specific part number. Substitute parts with active status (RG2012P-7872-W-T5 and RG2012N-7872-W-T1) are available to ensure design continuity and supply chain reliability.

Q: Are the substitute parts compatible with existing PCB designs for RG2012P-7872-W-T1?

A: Yes. Both substitute parts maintain identical package dimensions (0805 / 2012 Metric), footprint, and termination configuration (2 terminations). PCB layouts and assembly processes require no modification.

Q: What is the significance of Tape & Reel packaging for the substitute parts?

A: Tape & Reel (TR) packaging is the standard format for automated PCB assembly processes. This packaging format does not affect electrical performance or component functionality. It provides improved handling efficiency in high-volume manufacturing environments compared to bulk packaging.

Q: Are both substitute parts AEC-Q200 qualified?

A: Yes. Both RG2012P-7872-W-T5 and RG2012N-7872-W-T1 carry AEC-Q200 automotive qualification, anti-sulfur coating, and ROHS3 compliance, matching the main part specifications.

Q: Which substitute should be selected for new designs?

A: For new designs, RG2012N-7872-W-T1 is recommended due to its superior temperature coefficient (±10ppm/°C), providing enhanced precision and stability. For direct replacement of existing designs, RG2012P-7872-W-T5 offers electrical equivalence with active product status.
