Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-4870-C-T5 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 487 Ohms (exact match required)
• Package format: 0805 (2012 Metric) (physical and electrical compatibility)
• Power rating: 0.125W (1/8W) (thermal design compatibility)
• Composition: Thin Film (electrical performance characteristics)
• Features: Anti-Sulfur, Automotive AEC-Q200 (environmental and reliability requirements)
• Temperature coefficient: ±5ppm/°C (temperature stability)
• Operating temperature range: -55°C ~ 155°C (thermal operating envelope)
• Compliance: ROHS3, REACH Unaffected (regulatory requirements)

Variable Parameter (Substitution Basis):

• Tolerance: The main part specifies ±0.25%. Substitute parts with equal or tighter (lower) tolerance values are functionally equivalent and directly interchangeable, as they meet or exceed the original specification.

All four substitute parts listed maintain identical values across all mandatory parameters. Tolerance variations represent upgrades to higher precision specifications while preserving full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitution Candidates:

All four substitute parts are direct functional equivalents to the RG2012V-4870-C-T5. Selection among active alternatives is based on tolerance requirements and product availability:

RG2012V-4870-W-T5 (±0.05% tolerance, 1072 units in stock) is the preferred substitute when tolerance specifications permit. This part maintains identical packaging (Tape & Reel), active product status, and full AEC-Q200 automotive qualification. The tighter tolerance represents an upgrade path for applications requiring improved precision while maintaining all other electrical and mechanical characteristics.

RG2012V-4870-W-T1 (±0.05% tolerance, 989 units in stock) provides equivalent electrical performance with alternative packaging configuration (Tape & Reel). Selection between RG2012V-4870-W-T5 and RG2012V-4870-W-T1 depends on specific tape reel specifications required by manufacturing processes.

RG2012V-4870-B-T5 (±0.1% tolerance, 666 units in stock) serves applications where moderate tolerance improvement is acceptable. This part maintains the same packaging format as the original part.

RG2012V-4870-P-T1 (±0.02% tolerance, 678 units in stock) is specified for applications requiring the highest precision. This part delivers the tightest tolerance specification available within the equivalent parts group.

All substitute parts carry active product status, ensuring long-term availability and supply chain continuity. ROHS3 compliance and AEC-Q200 automotive qualification are maintained across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-4870-B-T5, RG2012V-4870-P-T1, RG2012V-4870-W-T1, and RG2012V-4870-W-T5 be used as direct replacements for RG2012V-4870-C-T5?

A: Yes. All four parts are direct functional equivalents. They maintain identical resistance values (487 Ohms), power ratings (0.125W), package formats (0805), composition (thin film), automotive qualification (AEC-Q200), and operating temperature ranges (-55°C ~ 155°C). The substitute parts feature equal or tighter tolerance specifications, making them fully compatible with designs originally specified for the RG2012V-4870-C-T5.

Q: What is the difference between the substitute parts?

A: The substitute parts differ only in tolerance specification. RG2012V-4870-P-T1 offers ±0.02% tolerance (highest precision), RG2012V-4870-B-T5 and RG2012V-4870-W-T5 and RG2012V-4870-W-T1 offer ±0.1%, ±0.05%, and ±0.05% tolerances respectively. All other electrical and mechanical parameters remain identical. Selection depends on the precision requirements of the specific application.

Q: Are there packaging differences between the substitute parts?

A: All substitute parts use Tape & Reel (TR) packaging in the 0805 (2012 Metric) form factor. Physical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and maximum seated height (0.020", 0.50mm) are identical across all parts. Packaging differences relate to tape reel specifications, which are determined by manufacturing and assembly equipment requirements.

Q: Does the obsolete status of RG2012V-4870-C-T5 affect circuit performance?

A: No. The obsolete status indicates that the original part is no longer manufactured. However, the electrical and mechanical specifications remain valid. The substitute parts, all with active product status, provide identical performance characteristics and are suitable for new designs and production runs.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts carry automotive AEC-Q200 qualification and anti-sulfur construction, meeting the same reliability and environmental standards as the original part. ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) are maintained across all alternatives.

Q: Which substitute part should be selected for highest precision applications?

A: RG2012V-4870-P-T1 provides the tightest tolerance specification at ±0.02%, suitable for precision analog circuits, reference networks, and measurement applications where resistance accuracy is critical.

Q: Can substitute parts be mixed within a single assembly?

A: Yes. All substitute parts are electrically and mechanically equivalent. However, design documentation and bill of materials should specify a single part number to maintain consistency in procurement, traceability, and quality control processes.
