Engineering Selection Recommendations
Direct Equivalent Substitutes (Identical Specifications):
The RG2012P-2873-B-T5 is the primary direct equivalent. This part maintains identical electrical and mechanical specifications to the obsolete RG2012P-2873-B-T1, with the distinction of active product status and Tape & Reel packaging. Both components are manufactured by Susumu within the RG series, feature AEC-Q200 automotive qualification, and operate across the full -55°C to 155°C temperature range.
The ERA-6AEB2873V (Panasonic Electronic Components, ERA-6A series) provides an alternative direct equivalent with identical resistance, tolerance, power rating, and temperature coefficient. This part carries AEC-Q200 qualification and is actively produced with substantial inventory availability.
The RT0805BRD07287KL (YAGEO, RT series) matches all critical electrical parameters and operates within the required temperature range. This part is supplied in Cut Tape and Digi-Reel packaging formats and maintains active production status.
Upgraded Substitutes (Superior Performance):
The RG2012N-2873-B-T5 offers improved temperature coefficient performance (±10ppm/°C versus ±25ppm/°C) while maintaining all other specifications. This upgrade reduces temperature-induced resistance drift and is suitable for precision applications requiring enhanced stability.
The RG2012N-2873-W-T1 provides the tightest tolerance specification (±0.05% versus ±0.1%) combined with improved temperature coefficient (±10ppm/°C). This upgrade is appropriate for high-precision analog circuits and measurement applications.
The RG2012P-2873-W-T5 offers improved tolerance (±0.05%) while maintaining the original temperature coefficient, suitable for applications requiring tighter resistance accuracy.

Frequently Asked Questions (FAQ)
Q: Can RG2012P-2873-B-T5 be used as a direct replacement for RG2012P-2873-B-T1?
A: Yes. The RG2012P-2873-B-T5 is a direct equivalent with identical electrical specifications (287 kΩ, ±0.1%, 0.125W, ±25ppm/°C) and mechanical package (0805). The primary difference is packaging format (Tape & Reel versus bulk) and active product status. Both components are manufactured by Susumu and carry AEC-Q200 qualification.
Q: What is the difference between the RG2012P and RG2012N series?
A: The RG2012N series offers improved temperature coefficient performance (±10ppm/°C) compared to the RG2012P series (±25ppm/°C). Both series maintain identical resistance values, tolerance options, and power ratings. The RG2012N is suitable for applications requiring enhanced temperature stability.
Q: Are there tolerance upgrade options available?
A: Yes. The RG2012N-2873-W-T1 and RG2012P-2873-W-T5 provide ±0.05% tolerance (tighter than the original ±0.1%). These upgrades are applicable in precision analog circuits, reference networks, and measurement instrumentation where tighter resistance accuracy is required.
Q: Can parts with higher power ratings be substituted?
A: Yes, with design consideration. The 3-2176094-7 (0.25W), TNPW0805287KBEEA (0.26W), and TNPW0805287KBEEN (0.26W) provide increased power dissipation capability. These parts are physically compatible with 0805 package footprints and can be used in applications where thermal margin or power handling requirements exceed 0.125W. Verify PCB thermal design and component placement for optimal performance.
Q: Which substitute parts carry automotive AEC-Q200 qualification?
A: The following parts maintain AEC-Q200 qualification: RG2012P-2873-B-T5, RG2012N-2873-B-T5, RG2012N-2873-W-T1, RG2012P-2873-W-T5, ERA-6AEB2873V, TNPW0805287KBEEA, and TNPW0805287KBEEN. These parts are suitable for automotive and high-reliability applications requiring automotive-grade component certification.
Q: What packaging formats are available for substitute parts?
A: Substitute parts are available in multiple packaging formats: Tape & Reel (TR) for automated assembly, Cut Tape (CT) with Digi-Reel for manual or semi-automated placement, and bulk packaging. Verify packaging compatibility with assembly equipment and procurement requirements before component selection.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) rating, meeting regulatory requirements for lead-free and hazardous substance restrictions.
Q: What is the temperature coefficient significance in resistor selection?
A: Temperature coefficient specifies resistance change per degree Celsius. The original RG2012P-2873-B-T1 exhibits ±25ppm/°C drift. Upgraded alternatives with ±10ppm/°C or ±15ppm/°C provide reduced temperature-induced resistance variation, improving circuit stability across the -55°C to 155°C operating range. Selection depends on application sensitivity to resistance drift.
Q: Can ERA-6AEB2873V or RT0805BRD07287KL be used without AEC-Q200 qualification concerns?
A: The ERA-6AEB2873V carries AEC-Q200 qualification and is suitable for automotive applications. The RT0805BRD07287KL does not carry AEC-Q200 certification. For automotive or high-reliability applications requiring automotive-grade qualification, select ERA-6AEB2873V or other AEC-Q200 qualified alternatives. For general industrial applications, RT0805BRD07287KL provides equivalent electrical performance.
