Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-5231-C-T5 is determined by strict equivalence in the following parameters:

Fixed Parameters (Non-Negotiable for Substitution):

• Resistance value: 5.23 kOhms
• Power rating: 0.125W (1/8W)
• Package type: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive rating: AEC-Q200
• Anti-sulfur construction
• RoHS3 compliance

Variable Parameters (Allowed to Differ):

• 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: Active alternatives are preferred over the obsolete main part.
• Packaging format: Tape & Reel (TR) is a standard distribution method compatible with automated assembly.

All identified substitute parts maintain identical electrical performance in resistance, power dissipation, and thermal characteristics while offering improved tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

All substitute parts are electrically and mechanically interchangeable with the RG2012V-5231-C-T5 due to identical resistance value, power rating, package dimensions, and thermal specifications. Selection among alternatives is based on tolerance requirements and product availability status.

Active Product Status: All four substitute parts carry active product status, eliminating long-term supply chain risk associated with the obsolete main part. This is the primary driver for substitution.

Tolerance-Based Selection:

• RG2012V-5231-B-T5 (±0.1% tolerance): Provides improved accuracy over the main part while maintaining standard thin film performance. Suitable for general automotive applications requiring tighter tolerance than ±0.25%.

• RG2012V-5231-W-T5 and RG2012V-5231-W-T1 (±0.05% tolerance): Offer enhanced precision for circuits sensitive to resistor value drift. Both variants are functionally equivalent; selection between them depends on packaging preference (T5 vs. T1 tape specifications).

• RG2012V-5231-P-T1 (±0.02% tolerance): Delivers the highest precision available in this series. Appropriate for precision measurement circuits, calibration networks, or applications requiring minimal resistance variation across temperature and time.

Compliance Verification: All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and anti-sulfur construction, ensuring compatibility with automotive assembly and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-5231-B-T5, RG2012V-5231-W-T5, RG2012V-5231-W-T1, and RG2012V-5231-P-T1 be used interchangeably with RG2012V-5231-C-T5?

A: Yes. All substitute parts are electrically and mechanically interchangeable. They share identical resistance value (5.23 kOhms), power rating (0.125W), package dimensions (0805/2012 Metric), thermal characteristics (±5ppm/°C, -55°C to 155°C), and automotive qualification (AEC-Q200). The substitutes offer equal or superior tolerance specifications.

Q: What is the difference between the substitute parts?

A: The substitute parts differ only in tolerance specification. RG2012V-5231-B-T5 provides ±0.1% tolerance, RG2012V-5231-W-T5 and RG2012V-5231-W-T1 provide ±0.05% tolerance, and RG2012V-5231-P-T1 provides ±0.02% tolerance. All other electrical and mechanical parameters are identical.

Q: Why is the main part RG2012V-5231-C-T5 listed as obsolete?

A: The RG2012V-5231-C-T5 is classified as obsolete, indicating it is no longer in active production. The substitute parts listed are active products with ongoing manufacturing and supply availability.

Q: Are there packaging differences between the substitute parts?

A: The main part is supplied in standard packaging format. All substitute parts are supplied in Tape & Reel (TR) format, which is the standard distribution method for automated assembly processes. The physical component dimensions and electrical characteristics remain unchanged.

Q: Which substitute part should I select for my application?

A: Selection depends on tolerance requirements. If the original ±0.25% tolerance is acceptable, RG2012V-5231-B-T5 (±0.1%) provides a cost-effective upgrade. For applications requiring tighter tolerance control, RG2012V-5231-W-T5 or RG2012V-5231-W-T1 (±0.05%) are appropriate. For precision circuits, RG2012V-5231-P-T1 (±0.02%) delivers maximum accuracy.

Q: Do all substitute parts meet automotive standards?

A: Yes. All substitute parts carry AEC-Q200 qualification, ROHS3 compliance, and anti-sulfur construction, meeting automotive assembly and environmental requirements identical to the main part.

Q: What is the temperature coefficient specification, and is it the same across all parts?

A: The temperature coefficient is ±5ppm/°C for all parts, including the main part and all substitutes. This specification defines the maximum resistance change per degree Celsius across the operating temperature range of -55°C to 155°C.
