Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-2551-C-T5 is determined by the following critical parameters that must remain constant across all equivalent parts:

Fixed Parameters (Non-Negotiable):

• Resistance value: 2.55 kOhms
• Power rating: 0.125W (1/8W)
• Package format: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Features: Anti-Sulfur, Automotive AEC-Q200
• Compliance: ROHS3, REACH Unaffected, MSL 1

Variable Parameter (Substitution Basis):

• Tolerance: The RG2012V-2551-C-T5 specifies ±0.25% tolerance. Substitute parts with equal or tighter (lower) tolerance values are electrically compatible and functionally superior for precision-critical applications.

All substitute parts listed maintain identical mechanical dimensions, thermal characteristics, and automotive qualification ratings. Tolerance improvements represent upgrades in resistive accuracy without compromising circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitution Candidates:

The RG2012V-2551-B-T5, RG2012V-2551-W-T1, and RG2012V-2551-W-T5 are direct functional equivalents with tighter tolerance specifications (±0.1% and ±0.05% respectively) compared to the original ±0.25%. These parts maintain identical mechanical, thermal, and electrical characteristics while offering improved resistive accuracy. All three are classified as active products with current manufacturing status.

Premium Substitution Option:

The RG2012V-2551-P-T1 represents the highest precision alternative with ±0.02% tolerance, suitable for applications requiring exceptional resistive accuracy. This part maintains all other electrical and mechanical specifications identical to the main part while providing superior tolerance performance.

Compliance and Certification:

All substitute parts retain full AEC-Q200 automotive qualification, anti-sulfur construction, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1). These certifications ensure compatibility with automotive and high-reliability applications without design modification.

Packaging Consideration:

The main part RG2012V-2551-C-T5 is supplied in standard packaging format. All substitute parts are supplied in Tape & Reel (TR) packaging, which is standard for production environments and compatible with automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-2551-B-T5 be used as a direct replacement for RG2012V-2551-C-T5?

A: Yes. The RG2012V-2551-B-T5 is a direct functional equivalent with identical resistance value (2.55 kOhms), power rating (0.125W), package format (0805), and operating temperature range (-55°C ~ 155°C). The tolerance specification is tighter (±0.1% versus ±0.25%), which represents an improvement in resistive accuracy without affecting circuit compatibility.

Q: What is the difference between the tolerance ratings of these substitute parts?

A: Tolerance defines the maximum allowable deviation from the nominal resistance value. The RG2012V-2551-C-T5 allows ±0.25% deviation. Substitute parts offer tighter tolerances: RG2012V-2551-B-T5 (±0.1%), RG2012V-2551-W-T1 and RG2012V-2551-W-T5 (±0.05%), and RG2012V-2551-P-T1 (±0.02%). Tighter tolerance means more precise resistance values, beneficial for precision-critical circuits.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification, anti-sulfur construction, and identical thermal performance specifications. They are suitable for automotive and high-reliability applications without design modification.

Q: What is the significance of the packaging difference (standard versus Tape & Reel)?

A: The main part RG2012V-2551-C-T5 uses standard packaging, while substitute parts use Tape & Reel (TR) packaging. Tape & Reel is the industry standard for automated assembly and production environments. Both packaging formats contain identical components; the difference is in delivery and handling format only.

Q: Can I use RG2012V-2551-P-T1 in place of RG2012V-2551-C-T5?

A: Yes. The RG2012V-2551-P-T1 is fully compatible with identical mechanical and electrical specifications. It offers superior tolerance performance (±0.02% versus ±0.25%), making it suitable for applications requiring higher resistive precision. All other parameters, including package format, power rating, and temperature range, remain identical.

Q: Why is the original part classified as obsolete?

A: Product obsolescence typically reflects manufacturing discontinuation by the supplier. Active substitute parts with identical or superior specifications are available to ensure design continuity and supply chain reliability for ongoing production.

Q: Are there any thermal or mechanical differences between the main part and substitutes?

A: No. All parts maintain identical thermal coefficients (±5ppm/°C), operating temperature ranges (-55°C ~ 155°C), physical dimensions (0.079" L x 0.049" W), and package format (0805 / 2012 Metric). Differences are limited to tolerance specifications and product status.
