Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-1821-C-T5 is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Resistance value: 1.82 kOhms
• Power rating: 0.125W (1/8W)
• Package format: 0805 (2012 Metric)
• Composition: Thin Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Physical dimensions: 0.079" L x 1.25mm W, 0.020" max height
• Compliance: ROHS3, AEC-Q200

Variable Parameters (Substitution Basis):

• Tolerance: The main part specifies ±0.25%. Substitute parts with tighter tolerances (±0.1%, ±0.05%, ±0.02%) are electrically compatible and represent performance upgrades.
• Product status: The main part is obsolete. All substitute parts are active and available.
• Packaging format: The main part uses bulk packaging. Substitute parts are supplied in Tape & Reel (TR) format, which is standard for production environments.

All substitute parts maintain identical electrical performance in circuits designed for the RG2012V-1821-C-T5 while offering improved tolerance specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Criteria:

Frequently Asked Questions (FAQ)

Q: Can RG2012V-1821-C-T5 be directly replaced with any of the substitute parts?

A: Yes. All four substitute parts are direct replacements. They maintain identical resistance value (1.82 kOhms), power rating (0.125W), package format (0805), composition (thin film), temperature coefficient (±5ppm/°C), operating range (-55°C to 155°C), and automotive certifications (AEC-Q200). The substitutes offer tighter tolerance specifications, which are compatible with circuits designed for the original ±0.25% tolerance.

Q: What is the difference between the substitute parts?

A: The substitute parts differ only in tolerance specification and packaging format. RG2012V-1821-B-T5 offers ±0.1% tolerance, RG2012V-1821-W-T1 and RG2012V-1821-W-T5 offer ±0.05% tolerance, and RG2012V-1821-P-T1 offers ±0.02% tolerance. All are supplied in Tape & Reel format. Tighter tolerance specifications provide improved accuracy for precision applications.

Q: Why is the main part listed as obsolete?

A: The RG2012V-1821-C-T5 is classified as obsolete, indicating it is no longer in active production. All substitute parts are active products with current manufacturing and inventory availability, ensuring long-term supply chain reliability.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification and anti-sulfur construction, identical to the main part. They are approved for automotive-grade applications across the full operating temperature range of -55°C to 155°C.

Q: What is the significance of the packaging format difference?

A: The main part uses bulk packaging, while all substitutes are supplied in Tape & Reel (TR) format. Tape & Reel is the standard packaging for automated assembly and production environments. This format difference does not affect electrical or mechanical compatibility; it reflects modern manufacturing practices.

Q: Which substitute should be selected for maximum precision?

A: RG2012V-1821-P-T1 provides the tightest tolerance specification at ±0.02%, suitable for precision measurement, calibration, and high-accuracy analog circuits. This part is active with 949 units in stock.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the environmental and regulatory compliance of the main part.
