Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-112-P-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.1 kOhms
• Tolerance: ±0.02%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The RG2012V-112-P-T1 qualifies as a direct substitute based on identical electrical specifications, mechanical dimensions, and environmental ratings. The primary distinction is product status (active versus obsolete) and packaging format (Tape & Reel versus standard packaging), with a secondary improvement in temperature coefficient performance.

Parameter Comparison

Engineering Selection Recommendations

The RG2012V-112-P-T1 is the direct functional equivalent for applications currently specified with RG2012N-112-P-T1. Selection of this substitute is supported by:

Product Status: The RG2012V-112-P-T1 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete RG2012N-112-P-T1.

Electrical Equivalence: Both parts deliver identical resistance (1.1 kOhms), tolerance (±0.02%), and power rating (0.125W). The substitute exhibits improved temperature coefficient performance (±5ppm/°C versus ±10ppm/°C), providing enhanced stability across the full operating temperature range of -55°C to 155°C.

Compliance and Certifications: Both components maintain ROHS3 compliance, AEC-Q200 automotive qualification, and identical moisture sensitivity ratings (MSL 1). Anti-sulfur coating is present on both variants, supporting reliability in corrosive environments.

Mechanical Compatibility: Identical 0805 (2012 Metric) package dimensions and termination configuration ensure direct PCB layout compatibility without design modification.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume production environments and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-112-P-T1 be used as a direct replacement for RG2012N-112-P-T1 in existing designs?

A: Yes. Both parts share identical electrical specifications (1.1 kOhms ±0.02%, 0.125W), mechanical dimensions (0805 package), and environmental ratings. The substitute is electrically and mechanically interchangeable without circuit modification.

Q: What is the significance of the temperature coefficient difference between the two parts?

A: The RG2012V-112-P-T1 exhibits a temperature coefficient of ±5ppm/°C compared to ±10ppm/°C for the RG2012N-112-P-T1. This represents improved temperature stability, resulting in tighter resistance tolerance maintenance across the -55°C to 155°C operating range. For precision applications, this provides enhanced performance.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components maintain identical compliance profiles: ROHS3 certification, AEC-Q200 automotive qualification, and MSL 1 moisture sensitivity rating. Both feature anti-sulfur coating for enhanced reliability.

Q: What is the impact of Tape & Reel packaging on component selection?

A: Tape & Reel (TR) packaging is the standard format for automated pick-and-place assembly and high-volume production. This packaging format does not affect electrical or mechanical performance and is compatible with standard SMD assembly equipment.

Q: Why is the RG2012N-112-P-T1 classified as obsolete?

A: Obsolescence indicates that the manufacturer has discontinued production of this specific part variant. The RG2012V-112-P-T1 represents the active production equivalent, ensuring continued availability and supply chain support.

Q: Are there any design considerations when transitioning from RG2012N-112-P-T1 to RG2012V-112-P-T1?

A: No design modifications are required. The parts are mechanically and electrically equivalent. Standard component handling procedures for thin film resistors with MSL 1 rating apply to both variants.
