RG2012P-1872-D-T5 Equivalent & Substitute Parts

Part Overview

The RG2012P-1872-D-T5 is an 18.7 kOhms ±0.5% thin film chip resistor manufactured by Susumu in 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and features anti-sulfur coating with automotive AEC-Q200 qualification. The part operates across -55°C to 155°C with a temperature coefficient of ±25ppm/°C and is RoHS3 compliant with MSL 1 rating. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: resistance value (18.7 kOhms), package format (0805), composition (thin film), operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3). The identified substitute parts maintain these core specifications while varying in tolerance and power rating.

Tolerance upgrades from ±0.5% to ±0.1% represent improved precision and are electrically compatible. Power rating increases from 0.125W to 0.25W provide enhanced thermal margin without affecting circuit operation. All substitute parts are packaged in 0805 format with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maintain the same temperature coefficient and operating range.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain electrical equivalence with the RG2012P-1872-D-T5 across the critical parameters of resistance, package format, composition, temperature range, and RoHS3 compliance.

RT0805BRD0718K7L (YAGEO) and ERA-6AEB1872V (Panasonic) provide tolerance improvement to ±0.1% while maintaining the 0.125W power rating and identical operating specifications. The ERA-6AEB1872V additionally carries AEC-Q200 automotive qualification matching the original part's certification status.

2-2176093-9 (TE Connectivity) offers increased power dissipation capability at 0.25W with ±0.1% tolerance and maintains full electrical compatibility. This part does not carry AEC-Q200 rating and exhibits a maximum seated height of 0.026" compared to the original 0.020", which may require verification in space-constrained applications.

For automotive applications requiring AEC-Q200 compliance, ERA-6AEB1872V is the direct functional equivalent. For general industrial applications, all three substitutes are electrically compatible. The TE Connectivity part provides thermal margin enhancement suitable for higher dissipation scenarios.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0718K7L replace RG2012P-1872-D-T5 in automotive applications?

A: RT0805BRD0718K7L is electrically compatible and maintains all core specifications including package, resistance, temperature range, and RoHS3 compliance. However, it does not carry AEC-Q200 automotive qualification. For applications requiring automotive certification, ERA-6AEB1872V is the appropriate substitute.

Q: What is the significance of the tolerance upgrade from ±0.5% to ±0.1%?

A: The tolerance upgrade represents improved precision in resistance value. All substitute parts with ±0.1% tolerance maintain tighter resistance bands, which may benefit circuits requiring higher accuracy. This is a performance enhancement and does not affect backward compatibility.

Q: Is the 2-2176093-9 suitable for direct replacement in space-constrained PCB layouts?

A: The 2-2176093-9 has a maximum seated height of 0.026" (0.65mm) compared to the original part's 0.020" (0.50mm). In applications with minimal clearance above the component, this height difference must be evaluated against available board space.

Q: Are all substitute parts available in Tape & Reel packaging?

A: All identified substitute parts are supplied in Tape & Reel (TR) packaging format, maintaining consistency with the original part's packaging specification.

Q: What is the impact of the power rating difference in 2-2176093-9?

A: The 2-2176093-9 is rated for 0.25W (1/4W) compared to the original 0.125W (1/8W). This higher power rating provides additional thermal margin and does not negatively affect circuit operation. The component remains suitable for applications designed for 0.125W dissipation.

Q: Do all substitute parts maintain the same temperature coefficient?

A: All substitute parts maintain the ±25ppm/°C temperature coefficient and operate across the identical -55°C to 155°C temperature range as the original RG2012P-1872-D-T5.
