Parameter Comparison

Engineering Selection Recommendations

RT0805BRD0751R1L (YAGEO): Direct upgrade offering tighter tolerance (±0.1% vs ±1%) and improved temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical power rating and package. Suitable for applications requiring enhanced precision. High inventory availability.

RT0805DRE0751R1L (YAGEO): Mid-tolerance option (±0.5%) with standard temperature coefficient. Maintains original power rating and package compatibility. Appropriate for applications where ±1% tolerance is not critical but improved performance over standard grade is desired.

9-1625868-5 (TE Connectivity Passive Product): Provides increased power dissipation capability (0.25W vs 0.125W) with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Suitable for applications requiring higher thermal headroom while maintaining electrical precision. Identical footprint and height compatibility confirmed.

ERA-6AEB51R1V (Panasonic Electronic Components): Automotive-grade AEC-Q200 certified thin film resistor with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Maintains 0.125W power rating and 0805 package. Highest inventory availability. Recommended for automotive applications or where AEC-Q200 qualification is required.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical operating temperature range (-55°C ~ 155°C).

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0751R1L replace RT0805FRE0751R1L in any application? A: Yes. RT0805BRD0751R1L is electrically and mechanically compatible. It provides superior tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it suitable for all applications where the original part is specified.

Q: What is the difference between RT0805DRE0751R1L and RT0805BRD0751R1L? A: Both are YAGEO 0805 thin film resistors with 51.1 Ohms resistance. RT0805BRD0751R1L offers ±0.1% tolerance and ±25ppm/°C temperature coefficient, while RT0805DRE0751R1L offers ±0.5% tolerance and ±50ppm/°C temperature coefficient. Selection depends on precision requirements.

Q: When should I use 9-1625868-5 instead of the YAGEO alternatives? A: Use 9-1625868-5 when your application requires higher power dissipation (0.25W vs 0.125W) or when TE Connectivity supply chain preference is established. It maintains ±0.1% tolerance and ±25ppm/°C temperature coefficient.

Q: Is ERA-6AEB51R1V suitable for non-automotive applications? A: Yes. ERA-6AEB51R1V is AEC-Q200 certified but not restricted to automotive use. It is a general-purpose thin film resistor with ±0.1% tolerance and ±25ppm/°C temperature coefficient, suitable for any precision analog application.

Q: Are all substitute parts available in the same packaging format? A: RT0805FRE0751R1L, RT0805BRD0751R1L, RT0805DRE0751R1L, and 9-1625868-5 are supplied in Tape & Reel (TR) format. ERA-6AEB51R1V is supplied in Cut Tape (CT) & Digi-Reel® format. Both formats are standard for SMD component distribution.

Q: What is the maximum height difference between substitute parts? A: RT0805FRE0751R1L, RT0805BRD0751R1L, RT0805DRE0751R1L, and ERA-6AEB51R1V have maximum seated height of 0.024" (0.60mm). 9-1625868-5 has maximum seated height of 0.026" (0.65mm), a difference of 0.002" (0.05mm), which is within standard PCB assembly tolerances.

Q: Do all parts meet RoHS3 compliance? A: Yes. All listed substitute parts are ROHS3 compliant and maintain MSL Level 1 (Unlimited) moisture sensitivity rating.
