Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-1051-B-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.05 kOhms
• Tolerance: ±0.1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Flexible Parameters (Substitution Allowed):

• Power Rating: Substitute parts with equal or higher power ratings are acceptable
• Manufacturer: Different manufacturers permitted
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) formats are interchangeable
• Features: Anti-sulfur and AEC-Q200 certifications are optional enhancements; absence does not preclude substitution
• Height - Seated (Max): Variation within 0.026" (0.65mm) maximum is acceptable for 0805 package

Three substitute parts meet these criteria with full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed are active in production status and ROHS3 compliant, meeting regulatory requirements for current electronic component applications.

RG2012P-1051-B-T5 (Susumu) - Primary specification. Includes anti-sulfur coating and AEC-Q200 automotive qualification. Lowest seated height at 0.020" (0.50mm). Current inventory: 759 units.

ERA-6AEB1051V (Panasonic) - Direct electrical and mechanical equivalent with identical power rating (0.125W). Includes AEC-Q200 automotive qualification matching the primary part. Seated height 0.024" (0.60mm). Highest inventory availability at 28,050 units. Suitable for automotive and industrial applications requiring AEC-Q200 compliance.

RT0805BRD071K05L (YAGEO) - Direct electrical and mechanical equivalent with identical power rating (0.125W). Seated height 0.024" (0.60mm). Inventory: 6,042 units. Suitable for general industrial applications where AEC-Q200 certification is not required.

2-2176092-0 (TE Connectivity) - Higher power rating at 0.25W (1/4W) provides thermal margin in applications with variable load conditions. Seated height 0.026" (0.65mm). Inventory: 1,778 units. Suitable for applications where increased power dissipation capability is beneficial. Does not include AEC-Q200 certification.

Selection between ERA-6AEB1051V and RT0805BRD071K05L depends on automotive qualification requirements. Selection of 2-2176092-0 is appropriate when higher power rating provides design margin without space constraints.

Frequently Asked Questions (FAQ)

Q: Can the 2-2176092-0 substitute for the RG2012P-1051-B-T5 in all applications?

A: The 2-2176092-0 is electrically and mechanically compatible. The higher power rating (0.25W vs. 0.125W) does not create incompatibility. However, the 2-2176092-0 lacks AEC-Q200 automotive certification. Applications requiring automotive qualification must use ERA-6AEB1051V or the primary RG2012P-1051-B-T5 part.

Q: What is the significance of the ±0.1% tolerance specification?

A: The ±0.1% tolerance indicates precision thin film resistor construction. All substitute parts maintain this tolerance specification, ensuring equivalent accuracy in circuit performance. This tolerance is critical for applications requiring stable reference resistances or precision signal conditioning.

Q: Are there physical space constraints when substituting between these parts?

A: All parts use the 0805 (2012 Metric) package with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Seated height varies between 0.020" and 0.026" (0.50mm to 0.65mm). Applications with height-constrained PCB layouts should prioritize RG2012P-1051-B-T5 (0.020" max) or ERA-6AEB1051V and RT0805BRD071K05L (0.024" max). The 2-2176092-0 at 0.026" maximum height is acceptable for most standard PCB designs.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging is supplied on continuous reels suitable for automated pick-and-place assembly equipment. Cut Tape and Digi-Reel packaging (ERA-6AEB1051V) is supplied in smaller quantities on tape strips. Both formats contain identical components. Selection depends on production volume and assembly equipment compatibility.

Q: Why does the RG2012P-1051-B-T5 include anti-sulfur coating?

A: Anti-sulfur coating protects the resistor element from corrosion in high-sulfur environments, extending component reliability in industrial and automotive applications. This feature is not present in the substitute parts. Applications in standard controlled environments do not require this feature.

Q: Is the ±25ppm/°C temperature coefficient specification critical for substitution?

A: Yes. All substitute parts maintain the identical ±25ppm/°C temperature coefficient. This specification determines resistor value stability across the -55°C to 155°C operating range. Substitution is valid only when this parameter matches.

Q: What does ROHS3 compliance indicate?

A: ROHS3 compliance certifies that the component meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All listed parts are ROHS3 compliant, meeting regulatory requirements for sale in regulated markets.

Q: Can these parts be used interchangeably in automotive applications?

A: Parts with AEC-Q200 certification (RG2012P-1051-B-T5 and ERA-6AEB1051V) are qualified for automotive use. The RT0805BRD071K05L and 2-2176092-0 lack this certification and should not be used in applications requiring automotive qualification without additional validation.
