Engineering Selection Recommendations

RG2012P-82R5-W-T5 (Direct Substitute)

This part provides direct electrical and mechanical equivalence to the RG2012P-82R5-W-T1. The primary distinction is product status: RG2012P-82R5-W-T5 is active and available in Tape & Reel packaging format, addressing the obsolescence of the main part. Temperature coefficient remains at ±25ppm/°C, maintaining identical thermal performance characteristics. This substitute is suitable for applications requiring no change to thermal stability specifications.

RG2012N-82R5-W-T1 (Upgrade Substitute)

This part offers enhanced performance through a reduced temperature coefficient of ±10ppm/°C compared to the main part's ±25ppm/°C specification. All other electrical and mechanical parameters remain identical. RG2012N-82R5-W-T1 is active and supplied in Tape & Reel format. This substitute is applicable for designs where improved temperature stability is beneficial or required.

Both substitutes maintain full compliance with AEC-Q200 automotive qualification, ROHS3 environmental standards, and identical mechanical footprint for direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-82R5-W-T5 be used as a direct replacement for RG2012P-82R5-W-T1?

A: Yes. RG2012P-82R5-W-T5 is electrically and mechanically identical to RG2012P-82R5-W-T1. The difference is packaging format (Tape & Reel versus bulk) and active product status. Both parts share identical resistance, tolerance, power rating, temperature coefficient, and package dimensions.

Q: What is the advantage of RG2012N-82R5-W-T1 over the main part?

A: RG2012N-82R5-W-T1 provides a temperature coefficient of ±10ppm/°C compared to ±25ppm/°C in RG2012P-82R5-W-T1. This results in improved stability across the -55°C to 155°C operating range. All other specifications remain equivalent.

Q: Are these parts interchangeable on the PCB?

A: Yes. All three parts share identical 0805 (2012 Metric) package dimensions: 0.079" L x 0.049" W with maximum seated height of 0.020". PCB footprints and assembly processes require no modification.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging is used for manual assembly or small-volume applications. Tape & Reel format is standard for automated pick-and-place assembly. Both formats contain the same component; packaging affects handling and assembly methodology only.

Q: Are all three parts AEC-Q200 qualified?

A: Yes. RG2012P-82R5-W-T1, RG2012P-82R5-W-T5, and RG2012N-82R5-W-T1 all carry AEC-Q200 automotive qualification and anti-sulfur coating, suitable for automotive applications.

Q: Do these parts require different storage or handling procedures?

A: No. All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Which substitute should be selected for new designs?

A: For new designs, either RG2012P-82R5-W-T5 or RG2012N-82R5-W-T1 is appropriate. RG2012N-82R5-W-T1 is recommended if improved temperature stability is a design requirement. Both are active products with established supply chains.
