Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0805FRE071K47L are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain the same resistance value (1.47 kOhms) and operating temperature range (-55°C ~ 155°C).

Mechanical Compatibility: All substitute parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm).

Composition: All substitute parts are thin film resistors, ensuring consistent performance characteristics.

Allowed Variation Parameters:

• Tolerance may be tighter (±0.5%, ±0.1%) than the original ±1%
• Power rating may be equal or higher (0.125W or 0.25W)
• Temperature coefficient may be equal or lower (±50ppm/°C or ±25ppm/°C)
• Manufacturer and series may differ
• Certifications and ratings may be enhanced (e.g., AEC-Q200 automotive qualification)

Parameter Comparison

Engineering Selection Recommendations

For Standard Applications: RT0805DRE071K47L provides improved tolerance (±0.5%) over the original ±1% specification while maintaining identical power rating and YAGEO manufacturing consistency.

For Precision Circuits: RT0805BRD071K47L or ERA-6AEB1471V offer ±0.1% tolerance with reduced temperature coefficient (±25ppm/°C), suitable for applications requiring tighter resistive accuracy.

For Automotive Applications: ERA-6AEB1471V is the only substitute qualified to AEC-Q200 automotive standard, appropriate for automotive-grade circuit designs.

For Higher Power Dissipation: RP73PF2A1K47BTDF provides doubled power rating (0.25W vs. 0.125W) while maintaining ±0.1% tolerance and ±25ppm/°C temperature coefficient, suitable for applications with increased thermal requirements.

Compliance Consideration: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage practices.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD071K47L be used as a direct replacement for RT0805FRE071K47L?

A: Yes. Both parts share identical resistance (1.47 kOhms), package (0805), power rating (0.125W), and operating temperature range (-55°C ~ 155°C). RT0805BRD071K47L offers improved tolerance (±0.1% vs. ±1%) and lower temperature coefficient (±25ppm/°C vs. ±50ppm/°C), making it a compatible upgrade.

Q: What is the difference between RT0805DRE071K47L and RT0805BRD071K47L?

A: Both are YAGEO thin film resistors in 0805 package with 1.47 kOhms resistance. RT0805DRE071K47L has ±0.5% tolerance and ±50ppm/°C temperature coefficient. RT0805BRD071K47L has tighter ±0.1% tolerance and lower ±25ppm/°C temperature coefficient. Selection depends on circuit precision requirements.

Q: Is RP73PF2A1K47BTDF compatible with the original part?

A: Yes, mechanically and electrically compatible. RP73PF2A1K47BTDF maintains the 0805 package footprint and 1.47 kOhms resistance. The key difference is higher power rating (0.25W vs. 0.125W), making it suitable for applications with greater power dissipation requirements.

Q: Why would I choose ERA-6AEB1471V over other substitutes?

A: ERA-6AEB1471V is the only substitute with AEC-Q200 automotive qualification. Select this part for automotive-grade applications requiring automotive industry certification. It also provides ±0.1% tolerance and ±25ppm/°C temperature coefficient.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, maintaining supply chain compatibility with the original RT0805FRE071K47L.

Q: Can I use a substitute part with higher tolerance (e.g., ±0.1%) in place of the original ±1% specification?

A: Yes. Tighter tolerance is always compatible with applications designed for looser tolerance. The substitute will meet or exceed the original specification requirements.
