Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-7871-P-T1 is determined by the following critical parameters:

Electrical Parameters:

• Resistance value: 7.87 kOhms (exact match required)
• Tolerance: ±0.02% (exact match required)
• Power rating: 0.125W minimum (equal or higher acceptable)

Mechanical Parameters:

• Package type: 0805 (2012 Metric) (exact match required)
• Physical dimensions: 0.079" L x 0.049" W, 0.020" max height (exact match required)
• Number of terminations: 2 (exact match required)

Compliance & Environmental Parameters:

• Composition: Thin Film (exact match required)
• Features: Anti-Sulfur, Automotive AEC-Q200 (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (exact match required)

The RG2012V-7871-P-T1 qualifies as a direct substitute based on matching all critical electrical, mechanical, and compliance parameters. The primary distinction is product status (active vs. obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can RG2012V-7871-P-T1 be used as a direct replacement for RG2012P-7871-P-T1?

A: Yes. Both components share identical resistance value (7.87 kOhms), tolerance (±0.02%), power rating (0.125W), package type (0805), and automotive AEC-Q200 qualification. Physical dimensions and termination count are identical, enabling direct PCB substitution without layout modifications.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and packaging format. RG2012P-7871-P-T1 is obsolete with standard packaging, while RG2012V-7871-P-T1 is active with Tape & Reel packaging. Additionally, RG2012V-7871-P-T1 features a superior temperature coefficient (±5ppm/°C vs. ±25ppm/°C).

Q: Are there any compatibility concerns with automated assembly?

A: No. Both components use identical 0805 (2012 Metric) package specifications. RG2012V-7871-P-T1 in Tape & Reel format is optimized for automated pick-and-place assembly, while RG2012P-7871-P-T1 standard packaging may require manual handling or custom feeder configuration.

Q: Do both parts meet automotive standards?

A: Yes. Both RG2012P-7871-P-T1 and RG2012V-7871-P-T1 carry AEC-Q200 automotive qualification and are rated for -55°C ~ 155°C operating temperature range, suitable for automotive and industrial applications.

Q: What is the impact of the temperature coefficient difference?

A: RG2012V-7871-P-T1 exhibits a tighter temperature coefficient (±5ppm/°C) compared to RG2012P-7871-P-T1 (±25ppm/°C). This results in improved resistance stability across the operating temperature range, beneficial for precision analog circuits and measurement applications.

Q: Are there any environmental or compliance differences?

A: No. Both components are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Environmental and regulatory compliance profiles are identical.
