• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Features: Anti-Sulfur, Automotive AEC-Q200 (exact match required)
• Temperature Coefficient: ±5ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) (exact match required)
• Height - Seated (Max): 0.020" (0.50mm) (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variation Parameter:

• Tolerance: Substitutes with equal or tighter (lower) tolerance values are acceptable. The main part specifies ±0.25%; substitutes with ±0.1%, ±0.05%, or ±0.02% tolerance are functionally compatible.

All substitute parts listed maintain identical electrical performance characteristics and mechanical compatibility while offering improved tolerance specifications or active product status.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts (RG2012V-301-B-T5, RG2012V-301-P-T1, RG2012V-301-W-T1, and RG2012V-301-W-T5) are direct functional equivalents to the RG2012V-301-C-T5 with the following considerations:

Product Status: The main part RG2012V-301-C-T5 is classified as obsolete. All substitute parts are active products with confirmed inventory availability, ensuring long-term supply chain continuity and design sustainability.

Tolerance Specifications: All substitute parts feature equal or superior tolerance performance compared to the main part. The main part specifies ±0.25% tolerance. Substitute options provide tighter tolerances: RG2012V-301-B-T5 (±0.1%), RG2012V-301-W-T1 and RG2012V-301-W-T5 (±0.05%), and RG2012V-301-P-T1 (±0.02%). Tighter tolerance specifications enhance circuit accuracy and performance stability without introducing compatibility issues.

Compliance and Certifications: All parts maintain identical AEC-Q200 automotive qualification, ROHS3 compliance, and anti-sulfur construction. Moisture Sensitivity Level 1 (Unlimited) is consistent across all options, eliminating moisture-related handling constraints.

Electrical and Mechanical Compatibility: Resistance value (300 Ohms), power rating (0.125W), package type (0805), physical dimensions, temperature coefficient (±5ppm/°C), and operating temperature range (-55°C ~ 155°C) are identical across all parts, ensuring direct pin-for-pin and functional compatibility.

Selection Criteria: Component selection should be based on application tolerance requirements. For applications requiring the original ±0.25% tolerance specification, RG2012V-301-B-T5 provides the closest match with improved product status. For applications benefiting from enhanced precision, RG2012V-301-P-T1 (±0.02%) offers the tightest tolerance specification. RG2012V-301-W-T1 and RG2012V-301-W-T5 provide intermediate tolerance performance (±0.05%) with active product status.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-301-B-T5, RG2012V-301-P-T1, RG2012V-301-W-T1, or RG2012V-301-W-T5 be used as direct replacements for RG2012V-301-C-T5?

A: Yes. All four substitute parts are direct functional equivalents. They maintain identical resistance value (300 Ohms), power rating (0.125W), package type (0805), physical dimensions, temperature coefficient, operating temperature range, and AEC-Q200 automotive qualification. The substitute parts feature equal or tighter tolerance specifications, which are compatible with applications designed for the original part.

Q: What is the difference between the substitute parts?

A: The primary difference among substitute parts is tolerance specification. RG2012V-301-B-T5 provides ±0.1% tolerance, RG2012V-301-W-T1 and RG2012V-301-W-T5 provide ±0.05% tolerance, and RG2012V-301-P-T1 provides ±0.02% tolerance. All other electrical and mechanical parameters are identical. Tighter tolerance specifications enhance circuit precision without affecting physical compatibility or thermal performance.

Q: Are there packaging differences between substitute parts?

A: The main part RG2012V-301-C-T5 does not specify packaging format in the provided data. All substitute parts are supplied in Tape & Reel (TR) packaging format. The 0805 (2012 Metric) package type, physical dimensions (0.079" L x 0.049" W), and height (0.020" max) are identical across all parts, ensuring compatibility with standard surface-mount assembly equipment and PCB layouts.

Q: Why is the main part RG2012V-301-C-T5 classified as obsolete?

A: The RG2012V-301-C-T5 is classified as obsolete, indicating it is no longer in active production. The substitute parts listed are active products with confirmed inventory availability, ensuring design continuity and supply chain reliability for new designs and production requirements.

Q: Do all substitute parts meet automotive qualification standards?

A: Yes. All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, anti-sulfur construction, and Moisture Sensitivity Level 1 (Unlimited). These certifications and features are identical to the main part, ensuring compatibility with automotive and industrial applications requiring these specifications.

Q: Which substitute part should be selected for maximum precision?

A: RG2012V-301-P-T1 provides the tightest tolerance specification at ±0.02%, offering maximum precision for applications requiring enhanced accuracy. This part is suitable for precision measurement circuits, reference networks, and applications where tolerance stack-up must be minimized.

Q: Are there temperature performance differences between substitute parts?

A: No. All substitute parts maintain identical temperature coefficient (±5ppm/°C) and operating temperature range (-55°C ~ 155°C). Temperature performance is consistent across all options, ensuring equivalent thermal stability and reliability across the specified operating environment.

Q: Can substitute parts be mixed in the same design or production batch?

A: Yes. All substitute parts are functionally equivalent and maintain identical electrical and mechanical specifications except for tolerance. Mixing parts with different tolerance specifications in the same design is acceptable if the circuit design accommodates the tolerance range of the loosest specification used. For consistency and simplified inventory management, using a single substitute part across a design is recommended.
