Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-4871-C-T5 is determined by strict equivalence in the following parameters:

Fixed Parameters (Non-Negotiable):

• Resistance value: 4.87 kOhms
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive rating: AEC-Q200
• Anti-sulfur construction
• RoHS3 compliance

Variable Parameter (Allows Substitution):

• Tolerance: The main part specifies ±0.25%. Substitute parts with equal or tighter (lower) tolerance values are electrically compatible and functionally superior for precision applications.

All substitute parts maintain identical mechanical dimensions (0.079" L × 0.049" W, 2.00mm × 1.25mm), height (0.020" maximum seated), and termination count (2). All substitute parts are active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: RG2012V-4871-W-T1 or RG2012V-4871-W-T5

Both variants offer ±0.05% tolerance with active product status. These parts provide improved tolerance performance over the obsolete RG2012V-4871-C-T5 while maintaining all electrical and mechanical specifications. The selection between T1 and T5 packaging variants depends on supply chain and reel configuration requirements; both are functionally equivalent.

Secondary Recommendation: RG2012V-4871-B-T5

This part provides ±0.1% tolerance with active status. It represents a moderate tolerance improvement suitable for applications where the original ±0.25% specification is adequate but enhanced precision is beneficial.

Precision-Critical Applications: RG2012V-4871-P-T1

For circuits requiring maximum tolerance control, the RG2012V-4871-P-T1 delivers ±0.02% tolerance. This part is appropriate for precision analog circuits, reference networks, and measurement instrumentation where tolerance stack-up must be minimized.

All substitute parts carry identical AEC-Q200 automotive qualification, anti-sulfur construction, and RoHS3 compliance as the original part. All substitute parts are currently in active production status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-4871-C-T5 be directly replaced with any of the substitute parts?

A: Yes. All substitute parts are direct replacements. They maintain identical resistance value (4.87 kOhms), power rating (0.125W), package (0805), composition (thin film), temperature coefficient (±5ppm/°C), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200). The substitute parts feature equal or superior tolerance specifications.

Q: What is the difference between the tolerance specifications?

A: Tolerance defines the maximum deviation from the nominal 4.87 kOhms resistance value. The main part specifies ±0.25%, meaning the actual resistance can range from 4.8478 kOhms to 4.8922 kOhms. Substitute parts with tighter tolerances (±0.1%, ±0.05%, ±0.02%) provide narrower resistance ranges, reducing circuit performance variation. Selection depends on circuit tolerance requirements.

Q: Are the packaging variants (T1 vs. T5) interchangeable?

A: The T1 and T5 designations refer to reel packaging configurations. Both variants contain identical components and are electrically and mechanically equivalent. Selection is based on supply chain availability and manufacturing line compatibility, not functional performance.

Q: Does the obsolete status of RG2012V-4871-C-T5 affect circuit performance?

A: No. The obsolete status indicates the part is no longer manufactured. However, existing inventory remains functional. Substitution with active parts ensures future availability and supply chain continuity for production and field service applications.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification, anti-sulfur construction, and RoHS3 compliance identical to the original part. They are suitable for automotive and industrial applications requiring automotive-grade reliability standards.

Q: What is the physical footprint compatibility?

A: All parts use the 0805 (2012 Metric) package with identical dimensions: 0.079" length × 0.049" width (2.00mm × 1.25mm) and 0.020" maximum seated height. PCB footprints and assembly processes require no modification.
