Engineering Selection Recommendations

Direct Replacement (Electrical Equivalence):

RG2012P-682-B-T5 and RT0805CRD076K8L provide direct electrical equivalence to the RG2012P-682-C-T5. Both maintain identical tolerance (±0.25%), temperature coefficient (±25ppm/°C), and power rating specifications. RG2012P-682-B-T5 is available in Cut Tape & Digi-Reel format, while RT0805CRD076K8L (YAGEO) is available in Tape & Reel format. Both are active products with full AEC-Q200 and ROHS3 compliance.

Performance Upgrade Options:

Susumu RG series parts with improved specifications are available as active alternatives:

RG2012N-682-B-T5 and RG2012N-682-W-T5: Offer tighter tolerance (±0.1% and ±0.05% respectively) with improved temperature coefficient (±10ppm/°C) while maintaining ±25ppm/°C or better performance envelope.
RG2012V-682-B-T5, RG2012V-682-W-T1, RG2012V-682-W-T5, and RG2012V-682-P-T1: Provide superior temperature stability with ±5ppm/°C coefficient. RG2012V-682-P-T1 offers the tightest tolerance specification (±0.02%) for precision applications.

All substitute parts maintain identical 0805 package dimensions, power rating, operating temperature range, and automotive qualification status. Selection between alternatives depends on tolerance and temperature coefficient requirements of the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-682-W-T5 be used as a direct replacement for RG2012P-682-C-T5?

A: Yes. RG2012N-682-W-T5 is electrically compatible. It maintains the same 6.8 kOhms resistance, 0.125W power rating, 0805 package, and operating temperature range. The tolerance is tighter (±0.05% versus ±0.25%), and the temperature coefficient is improved (±10ppm/°C versus ±25ppm/°C), making it a suitable upgrade. Packaging format differs (Tape & Reel versus original format), which may affect procurement logistics but not circuit performance.

Q: What is the difference between RG2012P and RG2012N and RG2012V series designations?

A: The letter designation indicates temperature coefficient performance. RG2012P series has ±25ppm/°C, RG2012N series has ±10ppm/°C, and RG2012V series has ±5ppm/°C. All three series are compatible for the same 6.8 kOhms 0805 package application. Selection depends on circuit requirements for temperature stability.

Q: Is RT0805CRD076K8L from YAGEO equivalent to the Susumu RG2012P-682-C-T5?

A: Yes. RT0805CRD076K8L provides electrical equivalence with matching 6.8 kOhms resistance, ±0.25% tolerance, ±25ppm/°C temperature coefficient, 0.125W power rating, and 0805 package. It is an active product with ROHS3 compliance. The primary difference is manufacturer (YAGEO versus Susumu) and physical height (0.024" maximum versus 0.020" maximum seated height).

Q: What does the letter suffix in part numbers (B, C, W, P) indicate?

A: The letter suffix indicates tolerance specification. C denotes ±0.25%, B denotes ±0.1%, W denotes ±0.05%, and P denotes ±0.02%. Tighter tolerance letters represent improved precision specifications.

Q: Can I substitute a part with tighter tolerance than the original specification?

A: Yes. Substituting with tighter tolerance (lower percentage value) is acceptable and represents an upgrade. For example, replacing ±0.25% with ±0.05% improves circuit accuracy without introducing incompatibility. The component will perform within the original design requirements while offering enhanced precision.

Q: What is the significance of the T1 and T5 suffixes in part numbers?

A: T1 and T5 designate packaging format and tape specifications for automated assembly. T1 typically indicates Cut Tape & Digi-Reel format, while T5 indicates standard Tape & Reel format. Both are compatible for the same circuit application; selection depends on procurement and assembly equipment compatibility.

Q: Are all listed substitutes AEC-Q200 qualified?

A: All Susumu RG series parts listed are AEC-Q200 qualified. RT0805CRD076K8L from YAGEO does not carry AEC-Q200 designation in the provided specifications. For automotive applications requiring AEC-Q200 compliance, Susumu RG series alternatives are required.

Q: What is the physical size difference between substitute parts?

A: All parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Maximum seated height varies slightly: Susumu RG series parts are 0.020" maximum, while RT0805CRD076K8L is 0.024" maximum. This minor height difference does not affect PCB layout compatibility for standard 0805 footprints.
