Frequently Asked Questions (FAQ)

Q: Can RG2012P-8451-W-T5 be used as a direct replacement for RG2012P-8451-W-T1?

A: Yes. RG2012P-8451-W-T5 is electrically and mechanically identical to RG2012P-8451-W-T1. The difference is packaging format (Tape & Reel versus bulk) and active production status. Both parts meet identical electrical specifications: 8.45 kOhms ±0.05%, 0.125W, 0805 package, ±25ppm/°C temperature coefficient, and AEC-Q200 automotive qualification.

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

A: The RG2012N series (RG2012N-8451-W-T1) provides ±10ppm/°C temperature coefficient. The RG2012V series provides ±5ppm/°C temperature coefficient. Both series maintain the same 8.45 kOhms resistance, 0.125W power rating, and 0805 package. The RG2012V series offers superior temperature stability for precision applications.

Q: Is RG2012V-8451-P-T1 compatible with designs specified for RG2012P-8451-W-T1?

A: Yes. RG2012V-8451-P-T1 is mechanically and functionally compatible. It provides tighter tolerance (±0.02% versus ±0.05%) and superior temperature coefficient (±5ppm/°C versus ±25ppm/°C). These are performance enhancements that do not compromise compatibility. The part occupies identical footprint (0805 package, 2.00mm x 1.25mm) and operates across the same temperature range (-55°C to 155°C).

Q: What does the "T1" and "T5" designation indicate?

A: The suffix designates packaging format and tape configuration. T1 and T5 both indicate Tape & Reel packaging suitable for automated assembly. Both formats are compatible with standard pick-and-place equipment. The original RG2012P-8451-W-T1 was supplied in bulk format; T1 and T5 variants provide equivalent parts in standard production packaging.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, anti-sulfur construction, and ROHS3 compliance. All parts are rated for -55°C to 155°C operating temperature range and maintain Moisture Sensitivity Level 1 (Unlimited).

Q: Which substitute part should be selected for new designs?

A: For new designs requiring specifications identical to RG2012P-8451-W-T1, select RG2012P-8451-W-T5. For applications benefiting from improved temperature stability, RG2012V-8451-W-T1 or RG2012V-8451-W-T5 are recommended.
