RG2012P-7873-D-T5 Equivalent & Substitute Parts

Part Overview

The RG2012P-7873-D-T5 is a 787 kOhms ±0.5% thin film chip resistor manufactured by Susumu in 0805 (2012 Metric) package format. This surface-mount device is rated for 0.125W (1/8W) power dissipation and is qualified to AEC-Q200 automotive standards with anti-sulfur coating. The part is active in production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent resistance values, power ratings, and package specifications are maintained while offering improved tolerance or alternative qualified sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-7873-D-T5 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain constant across all substitute parts:

• Resistance value of 787 kOhms
• Power rating of 0.125W (1/8W)
• Package format of 0805 (2012 Metric)
• Thin film composition
• Temperature coefficient of ±25ppm/°C
• Operating temperature range of -55°C to 155°C
• Two terminations
• RoHS3 compliance
• MSL rating of 1

Tolerance specifications may be improved (reduced) in substitute parts, as a tighter tolerance is functionally superior and maintains backward compatibility. All identified substitutes meet or exceed the original part's tolerance specification while maintaining identical electrical performance across the specified operating range.

Parameter Comparison

Engineering Selection Recommendations

Both identified substitute parts are functionally equivalent to the RG2012P-7873-D-T5 and are suitable for direct replacement in applications requiring 787 kOhms ±0.5% or tighter tolerance thin film resistors in 0805 package format.

ERA-6AEB7873V (Panasonic Electronic Components): This substitute offers ±0.1% tolerance, representing a fourfold improvement over the original specification. The part maintains AEC-Q200 automotive qualification and is active in production status. The seated height of 0.024" (0.60mm) is 0.004" greater than the original part and must be verified for clearance in space-constrained applications.

RT0805BRD07787KL (YAGEO): This substitute also provides ±0.1% tolerance with identical electrical specifications. The part is active in production status with RoHS3 compliance. The seated height of 0.024" (0.60mm) matches the Panasonic substitute and requires clearance verification in compact layouts.

Both substitutes maintain full compliance with RoHS3 and REACH requirements. Selection between substitutes should be based on supply chain availability, lead time requirements, and PCB layout constraints related to component height.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB7873V or RT0805BRD07787KL be used as direct replacements for RG2012P-7873-D-T5?

A: Yes. Both substitute parts maintain identical resistance value, power rating, package format, temperature coefficient, and operating temperature range. The improved tolerance specifications (±0.1% versus ±0.5%) provide enhanced precision while maintaining backward compatibility.

Q: What is the significance of the tolerance improvement in the substitute parts?

A: The substitute parts offer ±0.1% tolerance compared to the original ±0.5% tolerance. This represents a fourfold reduction in allowable resistance deviation, resulting in tighter circuit performance and improved predictability in precision applications. Tighter tolerance is functionally superior and does not create compatibility issues.

Q: Are there height differences between the original part and substitutes?

A: Yes. The RG2012P-7873-D-T5 has a maximum seated height of 0.020" (0.50mm), while both ERA-6AEB7873V and RT0805BRD07787KL have maximum seated heights of 0.024" (0.60mm). This 0.004" difference must be evaluated for PCB layout clearance, particularly in applications with height-constrained component placement or stacked configurations.

Q: Do all parts maintain automotive qualification?

A: The RG2012P-7873-D-T5 and ERA-6AEB7873V both carry AEC-Q200 automotive qualification. The RT0805BRD07787KL does not list AEC-Q200 qualification in the provided specifications. For automotive applications requiring AEC-Q200 compliance, ERA-6AEB7873V is the appropriate substitute.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts—RG2012P-7873-D-T5, ERA-6AEB7873V, and RT0805BRD07787KL—are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level).

Q: What packaging format is used for all parts?

A: All parts are supplied in Tape & Reel (TR) format, maintaining consistency with standard surface-mount assembly processes.
