Engineering Selection Recommendations
Direct Equivalent (Identical Specifications):
RG2012P-750-B-T5 is the direct equivalent to RG2012P-750-B-T1. Both parts share identical electrical and mechanical specifications with matching tolerance (±0.1%), power rating (0.125W), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C to 155°C). The primary difference is product status: RG2012P-750-B-T5 is active with 11,008 pieces in stock, whereas the original part is obsolete. This part maintains all automotive AEC-Q200 and anti-sulfur features of the original design.
Upgraded Alternatives (Enhanced Performance):
RG2012N-750-B-T5 and RG2012N-750-W-T5 offer improved temperature coefficient performance (±10ppm/°C versus ±25ppm/°C). RG2012N-750-W-T5 additionally provides tighter tolerance (±0.05% versus ±0.1%). Both maintain identical power rating, package, and operating temperature range. These upgrades are suitable for applications requiring superior temperature stability.
RG2012P-750-W-T5 provides tighter tolerance (±0.05%) while maintaining the original temperature coefficient (±25ppm/°C) and all other specifications.
Higher Power Rating Alternatives:
1-2176091-2 (TE Connectivity) and TNPW080575R0BEEA/TNPW080575R0BEEN (Vishay Dale) provide increased power dissipation capability (0.25W and 0.26W respectively) while maintaining 75 Ohm resistance, ±0.1% tolerance, and 0805 package. These parts are suitable for applications where thermal margin is required. TNPW series additionally extends operating temperature to 175°C.
Cross-Manufacturer Equivalents:
ERA-6AEB750V (Panasonic) and RT0805BRD0775RL (YAGEO) provide electrically identical specifications to the original part with AEC-Q200 qualification (Panasonic) or standard thin film construction (YAGEO). Both maintain 0.125W power rating and full operating temperature range.
MCU08050D7509BP100 (Vishay Beyschlag) provides equivalent specifications with anti-sulfur coating but operates to 125°C maximum, which is 30°C below the original specification. This part is suitable only for applications not requiring the full -55°C to 155°C range.

Frequently Asked Questions (FAQ)
Q: Can RG2012P-750-B-T5 be used as a direct replacement for RG2012P-750-B-T1?
A: Yes. RG2012P-750-B-T5 is a direct equivalent with identical electrical and mechanical specifications. The only difference is product status: the original is obsolete while the substitute is active. All performance characteristics, including tolerance, power rating, temperature coefficient, and operating range, are identical.
Q: What is the difference between the Susumu RG2012N and RG2012P series?
A: The primary difference is temperature coefficient. RG2012N series has ±10ppm/°C while RG2012P series has ±25ppm/°C. The "N" designation indicates improved temperature stability. Both series maintain identical resistance, tolerance options, power rating, and package specifications.
Q: Can I use TNPW080575R0BEEA instead of RG2012P-750-B-T1?
A: Yes, with consideration for power rating. TNPW080575R0BEEA provides 0.26W power dissipation versus the original 0.125W, offering greater thermal margin. All other electrical specifications match: 75 Ohm resistance, ±0.1% tolerance, ±25ppm/°C temperature coefficient, and -55°C to 155°C operating range. The extended temperature capability to 175°C is an additional benefit. Both parts carry AEC-Q200 qualification and anti-sulfur coating.
Q: Why does MCU08050D7509BP100 have a lower maximum operating temperature?
A: MCU08050D7509BP100 operates to 125°C maximum, which is 30°C below the original specification of 155°C. This part is suitable only for applications where the full temperature range is not required. For designs requiring operation to 155°C, select alternative parts that maintain the full range.
Q: Are all substitute parts available in Tape & Reel packaging?
A: Yes. All substitute parts listed are supplied in Tape & Reel (TR) packaging, consistent with the original part's packaging format for automated assembly.
Q: What is the significance of the "W" designation in RG2012N-750-W-T5?
A: The "W" designation indicates tighter tolerance specification of ±0.05% compared to ±0.1% in the "B" designation. RG2012N-750-W-T5 provides superior tolerance performance while maintaining all other specifications including the improved ±10ppm/°C temperature coefficient.
Q: Can I substitute a higher tolerance part (±0.1%) with a tighter tolerance part (±0.05%)?
A: Yes. Tighter tolerance is a performance upgrade and is compatible with designs specified for ±0.1% tolerance. The part will perform within the original tolerance specification while providing additional accuracy margin.
Q: Which substitute part offers the best overall performance upgrade?
A: RG2012N-750-W-T5 provides the most comprehensive performance upgrade with ±0.05% tolerance (tightest available), ±10ppm/°C temperature coefficient (most stable), while maintaining all other original specifications including 0.125W power rating, AEC-Q200 qualification, and anti-sulfur coating.
Q: Are there any compliance differences between substitute parts?
A: All substitute parts maintain ROHS3 compliance and MSL 1 rating. AEC-Q200 automotive qualification is present in Susumu RG series, Panasonic ERA-6AEB750V, and Vishay Dale TNPW series. Parts without AEC-Q200 designation (TE Connectivity 1-2176091-2, YAGEO RT0805BRD0775RL, Vishay Beyschlag MCU series) are suitable for non-automotive applications or where automotive qualification is not required.
Q: What is the inventory status of substitute parts?
A: RG2012P-750-B-T5 has the highest inventory at 11,008 pieces. ERA-6AEB750V (Panasonic) has 27,328 pieces available. RT0805BRD0775RL (YAGEO) has 9,208 pieces. TNPW080575R0BEEA has 5,792 pieces. Other parts have lower inventory levels ranging from 637 to 4,587 pieces. Original RG2012P-750-B-T1 has 786 pieces remaining.
