Frequently Asked Questions (FAQ)
Q: Can RG2012P-753-B-T5 directly replace RG2012P-753-B-T1?
A: Yes. RG2012P-753-B-T5 is electrically and mechanically identical to RG2012P-753-B-T1. The only difference is packaging format (Tape & Reel vs. Bulk). Both have 75 kOhms ±0.1%, 0.125W power rating, ±25ppm/°C temperature coefficient, and -55°C to 155°C operating range. RG2012P-753-B-T5 is active with significantly higher inventory availability.
Q: What is the difference between RG2012N and RG2012P series?
A: The RG2012N series has a temperature coefficient of ±10ppm/°C, while RG2012P series has ±25ppm/°C. Both series meet the original specification. RG2012N provides superior temperature stability for precision applications.
Q: Can I use a ±0.05% tolerance part instead of ±0.1%?
A: Yes. A ±0.05% tolerance part exceeds the ±0.1% requirement and is fully compatible. RG2012N-753-W-T5 and RG2012P-753-W-T5 offer this tighter tolerance.
Q: What is the difference between TNPW080575K0BEEA and TNPW080575K0BEEN?
A: Both parts are electrically identical: 75 kOhms ±0.1%, 0.26W power rating, ±25ppm/°C temperature coefficient, and -55°C to 175°C operating range. The difference is in the packaging suffix (BEEA vs. BEEN), which indicates different tape and reel configurations. Both are automotive AEC-Q200 qualified.
Q: Can I use a 0.25W or 0.26W rated resistor in place of a 0.125W rated resistor?
A: Yes. Higher power ratings are acceptable substitutes. The 0.125W specification represents the maximum power dissipation requirement. Parts rated for 0.25W or 0.26W can safely handle this load. TE Connectivity 8-2176093-3 (0.25W) and Vishay Dale TNPW parts (0.26W) are suitable alternatives.
Q: Are non-automotive qualified parts acceptable for automotive applications?
A: No. For automotive applications, use only AEC-Q200 qualified parts. MCU08050D7502BP500, RT0805BRD0775KL, and 8-2176093-3 lack automotive qualification and are not suitable for automotive designs.
Q: What is the operating temperature limitation of MCU08050D7502BP500?
A: MCU08050D7502BP500 has an operating temperature range of -55°C to 125°C, which is narrower than the original RG2012P-753-B-T1 specification of -55°C to 155°C. This part is unsuitable for applications requiring operation above 125°C.
Q: Can I use ERA-6AEB753V as a direct replacement?
A: Yes. ERA-6AEB753V (Panasonic) is a direct electrical and mechanical equivalent with identical specifications: 75 kOhms ±0.1%, 0.125W, ±25ppm/°C, -55°C to 155°C, and AEC-Q200 qualification. The only difference is the packaging format (Cut Tape & Digi-Reel vs. Bulk).
Q: What is the difference between Cut Tape and Tape & Reel packaging?
A: Cut Tape (CT) and Tape & Reel (TR) are different packaging and delivery formats. Cut Tape is supplied in smaller quantities on individual tape strips, while Tape & Reel is supplied on continuous reels for automated assembly. Both formats contain electrically identical components. Selection depends on production volume and assembly equipment compatibility.
Q: Why is RG2012P-753-B-T1 obsolete?
A: Product obsolescence is determined by the manufacturer. RG2012P-753-B-T5 is the active replacement from Susumu with identical specifications and higher inventory availability.
Q: Can I mix different manufacturers' parts in the same design?
A: Yes. All listed substitute parts meet the same electrical and mechanical specifications. However, verify that your design does not have specific manufacturer requirements or qualification restrictions before mixing parts from different manufacturers.
